TECHNICAL FIELD
[0001] The present invention relates to punching frames and more particularly to a punch designed to be accommodated by various types of such frames. BACKGROUND
[0002] Punch presses are typically configured to hold a plurality of tools to form a variety of shapes and sizes of notches i and / or holes in blade workpieces, for example, formed from blade metal. Tools of this type commonly include at least one punch frame and corresponding mold. In a multi-station punch press tower, a rotating tower is commonly used to hold a plurality of punch frames above a workpiece support surface, while a corresponding plurality of mold receiving frames is located below the workpiece support surface. In some cases, once a first set of tools has been used, it is exchanged for a second set of tools, then a third set, and so on. In some cases, the machine tool includes an elongated rail for storing the tool set in cartridges. The cartridges, for example, can be slidably engaged with the rail so that they can be slid back and forth in the direction in the mounting position. Once a first workpiece has been completely processed using the desired sequence of tool sets, a second workpiece can be processed, in some cases by starting over with the first tool set.
[0003] A conventional puncture frame includes a puncture guide and a puncture body or holder, as well as a puncture tip, which can be fixed either reliably or releasably to the puncture body. The body and the punch tip are slidably engaged within the limits of the punch guide for reciprocal and axial movement along a longitudinal central geometric axis of the punch guide. Such a punch frame and corresponding die are mounted on a press and located in a working position of the press, for example, below the piston (or integrally connected to the piston). In this way, when downward force is provided on the piston flange, the puncture tip is expelled from the puncture guide in response and through an opening in an extractor plate to form a notch or hole through a piece. blade work. The extractor plate, which is attached to one end of the puncture guide, prevents the workpiece from following the puncture tip by retracting it back into the puncture guide.
[0004] People skilled in the art know that puncture frames require regular maintenance and modification, for example, to sharpen or replace worn puncture tips, and to replace puncture tips of one shape (or projection) with those of alternative shape for defer press operations. In the case of puncture tips configured to be releasably attached to puncture bodies, these tips are generally frame-specific, that is, not interchangeable with other types of puncture frame. As a result, regular maintenance and modification to different puncture frames can involve a large amount of time and expense when it comes to maintaining sufficient stock of replacement puncture tips for each of the frames.

[0061] The following detailed description is exemplificative in nature and is not intended to limit the scope, applicability, or configuration of the invention in any way. Instead, the following description provides practical illustrations for implementing exemplary ■ modalities of the present invention. Examples of constructions, materials and dimensions are provided for selected elements, and all other elements employ what is known to people skilled in the field of the invention. Persons skilled in the art will recognize that many of the examples provided have suitable alternatives that can be used.
[0062] Figure IA shows a side cross-sectional view of a punch frame 10, according to certain embodiments of the invention. As is generally the case for puncture frames, the illustrated puncture frame 10 includes a puncture guide 12, a puncture body 14, and a puncture tip 16. As shown, the puncture guide 12 includes a side wall 18, with an extractor plate 20 coupled to a first end 22 of the side wall 18 and a spring pack frame (or driver) 24 coupled to a second end 26, opposite of the side wall 18. Various designs of extract plates and package frames springs are well known in the art. 0 versed professional |! in the art you will appreciate that the punching frame modalities described in this document could be configured for use with this extractor plate or other known ones, and spring pack frame designs. More significantly, the next review of this application, the skilled professional will appreciate that, similar to the general adaptability of plates and extractors, the puncture tip embodied in this document is designed to have a wide scope of adaptability with different puncture frame designs, β
[0063] Returning to the reference to the puncture frame 10 of Figure IA, in certain embodiments, the puncture guide 12 is tubular in shape. The invention should not be limited to this, however, since the punch guide 12 can very well take other shapes, for example, multifaceted shapes with discrete sides. As shown, the side wall 18 of the punch guide 12 forms a central cavity 28 for inserting the punch body 14 into it. Like the punch guide 12, in certain embodiments, the punch body 14 is tubular in order to enable the body 14 to slide within the limits of the puncture guide central cavity 28. As shown, a side wall 32 of the body punch 14 defines an opening 30 which passes through it, which is sized to accept a meat 34 within it. In certain embodiments, the opening 30 is defined can generally be perpendicular to the longitudinal extension of the puncture body 14. Therefore, the meat 34, when accommodated by the opening 30, has a longitudinal extension that is generally perpendicular to that of the puncture body 14.
[0064] Figure 1B illustrates an enlarged view of the punch body 14 and the punch tip 16 shown in Figure IA. Concerning frames of the punch tip 16 with the punch body 14, a component used to trigger the arrest or release of the tip 16 in relation to the body 14 is the meat 34. As shown, in certain embodiments, the opening 30 of the puncture body 14 for one side 32a of the side wall of puncture body 32 to the opposite side 32b of the side wall 32. In certain embodiments, the meat 34 is a rod-like body, and is sized to extend from the a side wall side 32a to the opposite side wall side 32b, which results in uniform stiffness over the longitudinal extent of the cam 34 when accommodated by the opening 30. Such stiffness is important when using the cam 34 in securing / releasing the puncture tip 16 in relation to the punch body 14. For example, at different times during the adjustment of the cam, forces are applied to the cam 34 (usually perpendicular to the length of the longitudinal cam) in opposite directions.
[0065] Although the opening of the punch body 30 is shown when passing through both opposite sides 32a and 32b of the side wall of the punch body 32, the opening 30 can alternatively be configured to pass through the one side 32a and still terminate just before passing through the other side 32b. Therefore, although not shown, opening 30 can be defined to form a pocket within the limits of the side 32b of the puncture body side wall 32, in order to retain the front end 34b of the meat 34 and still to prevent such an end I 34b protrude through side 32b. Regardless of whether the punch body opening 30 passes through both opposite sides 32a and 32b of the punch body side wall 32 or not, access can be made with respect to the meat 34 at its insertion point in the side wall 32 Such access allows the meat 34 to be selectively adjusted at opening 30. In certain embodiments, as further detailed below, such adjustment involves rotating meat 34 at opening 30. As detailed below, meat 34 is of a unique shape, which enables (for example, through its rotation I within the limits of the opening of the puncture body 30) a firing of other ancillary components within the limits II of the puncture body 14 to alternatively secure or release the puncture tip 16, as desired .
[0066] In addition to the meat 34, an addition to the ancillary components is a loader body 36, as embodied in Figures 1F and 1G. With reference to Figure 1B, the loader body 36 is inserted into a central cavity 38 of the punch body 14 and is defined with an orifice 40 configured to align with the opening of the punch body 30. Therefore, when inserted into the opening of the punch puncture body 30, cam 34 is further adapted to pass through the hole of the cam body 40. As described later, this coupling of the cam body 36 with cam 34 enables movement of the cam 36 by rotating the cam 34. As detailed later, other ancillary components that enable the tip of I punch 16 to be alternatively secured or released from the punch body 14 may include a plurality of springs 42, 44, and 46, a pusher-retainer 48, and a plurality of wedge members 50.
[0067] Figure 1C shows a perspective view of the punch body 14 and the punch tip 16, both in exploded frame view, according to certain embodiments of the invention. Also shown are the ancillary components mentioned above and used exemplarily when alternatively attaching or releasing the puncture tip 16 in relation to the puncture body 14. With reference to the puncture body 14, the meat 34 is shown before being inserted at the opening of the puncture body 30, and, • - i * as described above, serves as a trigger mechanism for the puncture tip 16 when it is alternatively secured or released. Figure ICC is a perspective view of the punch body 14 and the punch tip 16 as shown in Figure 1C, with extension rod 59 additionally shown, according to certain embodiments of the invention. The use of rod 59, as it should be appreciated, represents an exemplary means by which the punch body 14 can be configured to couple with a spring pack for the puncture frame (for example, when extending through the spring pack and threaded to a rear end).
[0068] Figures ID and IE show enlarged perspective views of cam 34, according to certain embodiments of the invention. Cam 34 includes a portion of 1 head 52 and a portion of stem 54. In certain embodiments, as shown in Figure IE, head portion 52 is configured for rotation with an alien wrench (as shown), Torx type, or similar. In certain embodiments, insertion and subsequent rotation of the meat 34 within the limits of the opening of the puncture body 30 are performed while the puncture body 14 is separated from the puncture guide 12. However, in other designs, the puncture guide 12 is configured with an opening in the side wall 18 inside it to allow rotation of the meat 34 while the punch body 14 is joined to the punch guide 12. For example, back to the reference to Figure 1A, such a punch guide opening could be configured similar to locks on the side wall of the punch guide 18 (like lock 29, shown when accommodating plug 31 to prevent pressure leakage from the punch guide 12). Consequently, as the punch body 14 is inserted into the central cavity 28 of the punch guide 12, the opening of the punch body 30 can be aligned with such a punch guide opening. When configuring the meat head portion 52 to be rotated through such an alien i or Torx type wrench, one end of such an wrench is narrow enough to be easily slid through such a puncture guide opening as well as opening the punch body 30 to rotate the meat 34.
[0069] The connection between the cam 34 (once inserted in the opening of the punch body 30) and the punch body 14 is provided through the use of a member disposed between them, which serves as a connecting member to hold the meat 34 to the body 14. In certain embodiments, as shown in Figure 1C, the member can be a ball 56 which is loaded into a depression 58 of the puncture body 14. The depression 58 is defined to open at the opening of the puncture body 30. Thus, once placed in the depression 58, the ball 56 is dimensioned to extend partially into the opening 30. The meat 34, in certain embodiments as shown in Figure 1D, includes a channel 60 that extends around a external side of the meat head portion 52, the channel 60 being dimensioned to accommodate the portion of the ball 56 that extends into the opening of the punch body 30. In certain embodiments, the channel 60 ii includes an inlet 60a that serves as an entry point for sphere 5 6 as the meat 34 is inserted into the opening of the punch body 30. Once the ball 56 enters the channel '60 and the meat 34 is subsequently rotated, the channel 60 rotates around the ball 56, which thus retain the meat 34 within the limits of the opening of the puncture body 30.
[0070] In certain embodiments, as additionally shown in Figures 1D and 1E, channel 60 includes one or more pockets 60b that extend away from channel 60 and towards (for example, in a direction generally parallel to) the portion of rod 54 of cam 34. In certain embodiments, channel 60 includes at least two such pockets 60b. Pockets 60b, which serve as holding points for ball 56 as channel 60 is rotated around it, are used as locking positions for meat 34 as it is rotated at the opening of the punch body 30. 1 According to further detailed in this document, such locking positions serve as positions in which the punch tip 16 can alternatively be attached to the punch body 14 or released from the punch body 14.
[0071] In connection with the pockets 60b described above, and back to the reference to Figures IA to 1C, a spring 42 is positioned in the opening of the punch body 30 and suspended there through contact with the loader body 36. Being thus, when meat 34 is inserted into IJ opening 30, its stem portion 54 passes through spring 42, while head portion 52 comes into contact with spring 42. Thus, when meat 34 is operationally coupled to the puncture body 14 (through the ball 56 being suspended within the limits of the channel 60) and the cam 34 is rotated into a position so that the ball 56 is on top of one of the pockets 60b, the force of the spring 42 on the portion of head of the meat 52 results in seating the ball 56 within said pocket 60b, which thus locks the meat 34 in such a position. To subsequently move the meat 34 from such a position, an inwardly directed force is applied against the head portion of the meat 52 (for example, through an alien screwdriver) to compress the spring 42. As a result of such an inwardly directed force, the ball 56 is displaced from pocket 60b and is directed back into channel 60 to enable cam rotation 34 to an additional position. The positioning of the cam 34, for securing and releasing the puncture tip 16 with the puncture body ■ is detailed later.
[0072] As additionally shown in i Figures ID and IE, the stem portion 54 of the meat 34 has: first and second separate segments 54a and 54b. As shown, segments 54a and 54b are configured to be out of alignment. In certain embodiments, the first segment 54a has a portion 54a 'that projects in a direction generally perpendicular to the longitudinal geometric axis A of the meat 34, while the second segment 54b has a portion 54b that projects in a generally opposite direction. The projecting portion 54a 'of segment 54a is particularly significant in the operation of the cam 34 as a firing mechanism, particularly through the loader body 36. As in the allusion made above, the enlarged perspective views of the loader body 36 are shown in the Figures 1F and 1G, according to certain embodiments of the invention. Such loader body 36 is configured to function with ancillary components, for example, one or more of the springs 44 and 46, the pusher-retainer 48, and the wedge members 50.
[0073] With reference to Figures 1B and 1C, the spring 4 4 is inserted in the central cavity 38 of the punch body 14 followed by the insertion of the loader body 36 in the cavity 38. As a consequence, the spring 44 provides a force in the body of carrier 36 in an outward direction with respect to the punch body 14 (i.e., towards a front end 14a of the body 14). However, as described above, subsequent insertion of the meat 34 through the opening of the punch body 30 and hole of the magazine body 40; retains the loader body 36 from being forced from the body of; punch 14 by spring 44. In this way, the carrier body 36 j is resiliently deflected towards the front end 14a of the punch body 14, yet the movement of the body 36 is dictated by rotating the cam 34. In particular , as the cam 34 is rotated in the punch body opening 30 so that the projecting portion 54a '(of segment 54a) is oriented towards an end | front 36a of the loader body 36, the body 36 is correspondingly propelled towards the front end 14a of the puncture body 14 and to an elevated (i.e., shallower) position in the central puncture body cavity 38. Such [ positioning of the loader body 36 is possibly best demonstrated in Figure 1B. In contrast, as the cam 34 is rotated in the punch body opening 30 so that the projecting portion 54a 'is oriented towards a rear end 36b of the loader body 36, the body 36 is moved from the front end 14a of the puncture body 14 and to a lowered (i.e., deeper) position 11 in the central puncture body cavity 38. Such positioning of the loader body 36 is possibly best demonstrated in Figure 11. As additionally ■ detailed below, such movement alternative (or positioning) of the loader body 36 is an additional trigger to alternatively hold or release the puncture tip 16 in relation to the puncture body 14.
[0074] With continued reference to Figures 1B and 1C, the spring 46 is inserted into a central cavity 36c of; loader body 36 followed by insertion in the cavity 36c of the pusher-retainer 48 (an enlarged perspective view of which is shown by way of example in Figure 1H). As a consequence, the spring 46 resiliently deflects the pusher-retainer 48 in an outward direction with respect to the loader body 36 (i.e., towards the front end 36a of the body 36). As further detailed below, the pusher-retainer 48 serves two purposes,> assisting in expelling the puncture tip 16 from the puncture body 14, and creating a condition that assists the puncture tip 16 to be inserted into an engaged position with o 1 punching body 14. In certain embodiments, an insertion ring 62 is additionally inserted and secured (for example, within a circular channel) in the central cavity 36c of the carrier body 36. Such a ring 62, once secured within the loader body cavity 36c prevents the pusher-retainer 48 from being forced away from the rear end 36b of the loader body 36 by the action of spring 46. In particular, an outer edge 48a of pusher-retainer 48, when entering in contact with the insert ring 62, prevents further movement out of the pusher-retainer 48 in the central cavity 36c of the loader body 36. However, the invention should not be limited to the use of such insert ring 62. Po For example, in certain embodiments, an II flange or other projecting portion may be coupled to the loader body cavity 36c or machined within it, thereby providing one. substitute for the insertion ring 62 when serving the same function. For this purpose, the surface area of such a rim that can be limited so that it only extends from two internal sides of the cavity 36c, when serving the same function. Next to the insertion ring 62 (or flange or protruding portion (s) of the central loader body cavity 36c, movement of the pusher-retainer 48 is additionally dictated by movement of the loader body 36 and corresponding movement of the wedge members 50, as further detailed below.
[0075] In summary, the cam 34 is configured for adjustment (for example, rotation) once positioned within the opening 30 of the punch body 14 and the orifice 40 of the loader body 36. In certain embodiments, the allowable range of rotation of the meat is dictated by the longitudinal extension of channel 60 defined in the head portion 52 of the meat, as the ball 56 seated on it prevents further rotation of the meat. The channel 60, in certain embodiments, is formed with one or more pockets 60b in which each serves as a rotatable locking position for the meat 34. In certain embodiments, the locking positions include a first position that allows the tip of the punch 16 is attached to the punch body 14 (in which the projecting portion 1 54a 'is oriented towards the front end; 36a of the loader body 36) and a second position that: allows the punch point 16 to be released (or inserted; into) of the punch body 14 (in which the projecting portion 54a 'is oriented towards the rear end 36b of the magazine body 36).
[0076] As mentioned above, although opposite movements of the loader body 36 are alternatively triggered by the rotation of the cam, it is believed that such movements can be as additional triggers to additionally secure or release the puncture tip 16 in relation to the puncture body 14. In certain embodiments, this additional firing involves the wedge members 50. Figures II and 1J show enlarged views of an exemplary wedge member 50. In certain embodiments, and in reference to Figures 1B and 1C, a plurality of the members of wedge 50 is used with the loader body 36, with slits 36d in the body 36 to correspondingly accommodate the members 50. Although three wedge members 50 are exemplified, the invention should not be limited to this. Instead, in certain embodiments,: any number of two or more wedge members 50 may be used, with each positioned correspondingly within one of the slots 36d of the loader body 36. In certain embodiments, as shown, the slits 36d are at the front end 36a of the loader body 36, and are generally defined equidistant around the circumference of the outer surface of the body. Figures IB, IK, IL, and 1M illustrate cross-sectional views of the punch body 14, showing different rotated positions of the cam 36 and corresponding effects on the loader body 36 and the wedge members 50, according to certain modalities of the invention. As further detailed below, with movement of the loader body 36 (by means of rotation of the cam 34), the wedge members 50 are moved correspondingly with respect to the slots of the loader body 36d and grooves 14b of the punch body 14 (located outside slits 36d).
[0077] For example, starting with Figure 1, the punch body 14 is shown without the punch tip 16, with the meat 34 being partially inserted into the opening 30 of the punch body 14 and hole 40 of the loader body 36 As described above, in certain embodiments, the punch body 14 is configured to be coupled in a | operational with the meat 34 by means of a ball and channel connection. As shown, no such connection is yet applicable due to the fact that the head portion 52 of the meat 34 is not yet fully inserted into the punch body opening 30 (as illustrated in the corresponding cross-section I of Figure IKK). In addition, none of the protruding portions 54a ', 54b' of the meat are visible. For that purpose, in certain embodiments, the loader body orifice 40 is defined so as to allow only the insertion of the meat 34 into it when the projecting portions 54a ', 54b' of the meat are generally oriented perpendicular to the puncture body front end 14a. Consequently, there is no force from the meat 34 (via the projecting portion 54a ') being directed I towards the loader body 36, and there is little corresponding force from the loader body 36 on the wedge members 50. As such, the members of wedge 50, when accommodated by the loader body slots 36d, are free to slide into the central cavity 36c of the loader body 36 (as shown).
[0078] In relation to Figure 1L, the body of; punch 14 is shown again without the punch tip 16; however, the cam 34 is shown to be completely inserted into the punch body opening 30 and magazine body hole 40. As such, in embodiments employing the ball and channel type connection described above the punch body 14 and cam 34, sphere 56 (not visible as it is positioned facing behind the meat head portion 52, still illustrated in the corresponding cross section of Figure ILL) is not only located in channel 60, but also in one of the pockets 60b to lock meat 34 in position. As shown, the spring 42 deflects the head portion 52 of the cam 34 so as to keep the ball in such pocket 60b and the cam 34 in such a rotated position. In particular, the illustrated position is to release (or insert) the punch tip 16 with respect to the punch body 14. In such a position, the projecting portion 54a 'of segment 54a is oriented towards the rear end 36b of the loader body 36, which in turn forces the body 36 into (that is, deeper or recessed into) the central puncture body cavity 38. Such an impulse into the loader body 36 in turn allows the members wedge 50 are pulled into (from the puncture body cavity 38) by way of their accommodation through the slots of the loader body 36d. In particular, the wedge members 50 are ■ pulled adjacent to the grooves 14b of the punch body 14. Such pull into the wedge members 50 along with the outward force of the pusher-retainer 48 (by means of its spring 46) results in pusher-retainer 48 in contact and forcing; members 50 protruding from loader body slots 36d and grooves 14b.
[0079] Looking at Figure 1M, the puncture tip 16 is shown to be partially inserted into the central cavity 38 of the puncture body 14. Similar to what is shown in Figure IL, the meat 34 is completely inserted into the body opening punch 30 and loader body hole 40; however, its front end 34b is shown to extend outside the punch body opening 30. Thus, in embodiments employing the ball and channel type connection described above the punch body 14 and cam 34, the ball 56 (again not visible as it is positioned facing behind the meat head portion 52, still illustrated in the corresponding cross section of Figure 1MM) is located in channel 60 and not in one of the> pockets 60b to lock the cam 34 in position . As shown, none of the protruding portions 54a ', 54b' of the meat are visible. In particular, portions 54a ', 54b' are new and generally oriented perpendicular to the front end puncture body 14a, still oriented 180 degrees from their positions described above with respect to the Figure; IK. Consequently, referring to Figure IL, the inwardly directed force applied to the loader body 36 is removed, resulting in the loader body 36 being pushed outward (i.e., towards the front end 14a of the punch body 14) by spring action 44. Such an impulse out of the loader body 36, in turn, forces the wedge members 50 to be pulled out through their accommodation by the loader body slits 36d. In particular, the wedge members 50 come into contact with the front and side surfaces 64 of the grooves 14b of the punch body 14. Such pull out of the wedge members 50 (by means of the loader body 36) in combination with the inclination the front and side surfaces 64 of the grooves 14b results in the wedge members 50 sliding along such surfaces 64, back through the slots of the loader body 36d so as to project into the central cavity 36c of the loader body 36. As shown, contact with the pusher-retainer 48 prevents the wedge members 50 from projecting too far into the central cavity 36c.
[0080] Finally, with reference to Figure 1B, the puncture body 14 is shown with the puncture tip 16 attached to it. Using the ball and channel connection described above the punch body 14 and cam 34, and similar to that described with Figures IL and ILL, ball 56 is located in another of the pockets 60b to lock the cam 34 in position, with the spring 42 deflecting the head portion 52 of the cam 34 so as to keep the ball 56 in such pocket 60b and the cam 34 is such a rotated position. In particular, the illustrated position is to hold the punch tip 16 in relation to the punch body 14. In such a position, the projecting portion 54a 'of the segment 54a is oriented towards the front end 36a of the loader body 36, which, in turn, forces the body 36 outwards (that is, shallower or higher inwards) from the central puncture body cavity 38. Continuing from what has been described above for Figure 1M, such a pull out of the body of puncture 38 loader 36 in turn forces the wedge members 50 further to be pulled out (from the central puncture body cavity 38) by means of their accommodation through the loader body slots 36d. Such additional pulling out of the wedge members 50 (by means of the loader body 36) in combination with the inclination of the II front and side surfaces 64 of the grooves 14b results in the wedge members 50 continuing to slide along such surfaces 64 and in the central cavity 38 of the punch body 14. Such a sliding action results in the wedge members 50 projecting further from the loader body slots 36d and in the central cavity 36c of the loader body 36.
[0081] As it should be appreciated, when inserting the puncture tip 16 in the central puncture body cavity 38, and even more in the central loader body cavity 36c, a coupling hub 16a of the puncture tip 16 contacts and forces the pusher-retainer 48 into the center loader body cavity 36c. Consequently, the pusher-retainer 48 is no longer in an elevated position within the central loader body cavity 36c in order to block the projecting movement of the wedge members 50. Consequently, the wedge members 50 are pushed to overlap the hub 16a of the punch tip 16 (to secure the tip 16 to the punch body 14) given the pull out of the wedge members 50 (by means of the loader body 36) in combination with the inclination of the front and side surfaces 64 of the grooves 14b. In further reference to Figure 1B, as the hub 16a of the punch tip 16 is inserted into the central cavities 38, 36c, movement into the hub 16a is prevented when an upper surface 16e of the hub 16a comes into contact with the ring insert 62. In turn, cam 34 is rotated as described above, with the wedge members! 50 locking hub 16a from its rear.
[0082] Figures 1A to 1M, as detailed above, belong to the modalities mainly associated with. puncture body 14 and the ancillary components used with it for arming / disarming the puncture tip 16 on it. However, the puncture point 16 incorporated into the frame is significant. In particular, a specific combination of the characteristics that belong to the punch tip 16 has been adopted (as further detailed below) to allow the tip 16 to have wide application. For example, these features allow the punch tip 16 to be potentially adaptable with a wide variety of punch body types (and corresponding punch frames) by limiting the complexity of the tip design (for example, to limit the corresponding costs 1 manufacturing). In addition, such a combination of features for the puncture tip 16 contributes to the ease with which the tip 16 can be attached and released from: such types of puncture body.
[0083] When detailing the design of the puncture tip 16, initially, reference is made to the puncture frame 10 of Figure IA, the puncture body 14 thereof, and the wedge members 50 used when additionally securing and releasing the puncture tip puncture 16 thereof. Figures II and 1J show perspective views of one of the wedge members 50, according to certain embodiments of the invention. As illustrated, the wedge member 50 has a curvature along its longitudinal extension so as to be generally compatible with the curvature of the punch tip hub 16a. In certain embodiments (as described above), in addition to the punch tip hub 16a, the wedge members 50 are configured to match the slots 36d of the loader body 36 and one or more of the frontmost surfaces 64 and 66 of the grooves of puncture body 14b.
[0084] In certain embodiments, as shown in Figures II and 1J (and in reference to Figure 1B), the wedge members 50 have main flat surfaces 50aa, 50bb, 50cc, and 50dd on each of their sides 50a, 50b, 50c, and 50d, respectively. Two of the flat surfaces 50aa, and 50cc (located on opposite sides 50a and 50c, respectively) allow firm accommodation of the wedge member 50 within the slot loader body 36d. However, such firm accommodation allows the members 50 to slide into the slits 36d, for example, as a result of contact with other bodies during movement of the loader body 36. In certain embodiments, the flat surfaces 50aa and 50cc run substantially parallel at; corresponding surfaces defining the loader body slits 36d. As described above, in certain embodiments, the flat surface 50bb (side 50b) is configured to match the most frontal surface 64 of each of the punch body grooves 14b. In certain embodiments, the inclined surface 50bb of the wedge members 50 and the more frontal inclined surface 64 of the grooves 14b have approximately the same angle of inclination in order to improve the sliding of the wedge members 50 out of the grooves 14b, as described above with reference to Figures 1B and 1M.
[0085] The side 50d of the wedge members 50 is configured to make contact (and move out of contact) with the puncture tip 16 to secure (and release / insert) the tip 16 with the puncture body 14. As described above, the punch tip 16 was designed to be applicable to a wide variety of punch bodies, having limited complexity in relation to the tip design. Consequently, greater application of the punch tip 16 in relation to various punch frame designs is likely, by avoiding significant manufacturing costs for the punch tip 16.: Throughout the design process, many factors have been considered. Although focus was given to the configuration of the 50d side of the wedge members 50, focus was also given to the corresponding surface (s) of the punch tip 16 which would be configured to match such a wedge member side 50d. For example, one consideration involved how many surfaces of the puncture tip 16 should contact (or stay out of contact) advantageously with the wedge members 50 to secure (or release) the tip 16 relative to the puncture body 14. Other considerations involved (i) how these puncture point surface (s) should be; advantageously shaped, (ii) which surface (s) of the wedge members 50 the puncture tip (s) surface should correspond to advantageously and, in addition, ( iii) how these puncture point surface (s) should align or combine advantageously with the corresponding surface (s) of the wedge members 50.;
[0086] With reference to Figures 2A to 2C, other punch points 16 'and 16 "are incorporated in the present document, in accordance with certain modalities of the invention. However, as will be appreciated, these punch points 16' and 16" "have characteristics similar to that of the puncture tip 16 to configure the puncture tips to be - applicable to a wide variety of puncture bodies (and corresponding puncture frames). In certain embodiments, as further detailed below, these characteristics refer to the design features of the punch tip hub 16a. Particular reference is made: hereafter to Figures 2A and 2B, in which each shows enlarged views of the puncture tip 16 'and its hub 16a' in certain modalities. However, as mentioned above, each of the punch points 16 and 16 "(possibly as best shown in Figures IB and 2C, respectively) shares similar characteristics in relation to the hub design. Consequently, the relevant hub features for the tips punch marks 16 and 16 "are identified with the same reference numerals, iterations still different from the numerals.
[0087] Looking at Figures 2A and 2B (and in reference to Figures 3B and 3C), the puncture tip 16 'is a body with a first end 17a' configured to be attached or released alternately with respect to a puncture body (such as the puncture body 14 ') and a second end 17b' which includes a working end of the tip 16 '. In certain embodiments, the puncture point 16 'is a single integral body; however, it should be appreciated that other designs could involve the puncture point 16 'being composed of separate counted pieces. In further reference to Figures 2A and 3C, the first end 17a 'of the punch tip 16' includes a hub 16a 'which is displaced from the remainder of the tip 16' by a neck or neck region 17c '. As shown, cube 16a 'has an upper area 18a', a side area 18b ', and a lower area 18c'. As shown, the lower area 18c 'of the hub 16a' and the neck 17c 'define a recess 16b' of the punch tip 16 '. In certain embodiments, a surface 16c 'of the lower hub area 18c' is configured to match only the wedge members (such as wedge members 50 'shown in Figure 3C). For this purpose, the punch point 16 'is configured so that the single surface 16c' of the lower hub area 18c 'contacts (or frees itself from contact with) the wedge members 50' when attaching (or releasing) ) the tip 16 'in relation to the puncture body 14'.
[0088] In further reference to Figures 2A and 3C, it was found that a stable coupling is provided for the puncture tip 16 'through contact with such a' single cube surface 16c 'in light of the plurality of wedge members 50' acting on surface 16c '. The hub surface 16c ', as described above, surrounds one of the surfaces that form the recess 16b' of the punch tip 16 '. The cube surface 16c ', in certain embodiments, defines 1 at least a quarter (25%) of the recess 16b'. In certain embodiments, the surface 16c 'represents the unique surface of the cube 16a' which extends between the lateral area of the cube 18b 'and the neck region 17c'. In such a case, the surface 16c 'represents a total surface area between the side cube area 18b' and the neck region 17c 'for the corresponding side 50dd of the wedge member 50' to match with it when attaching the tip punch 16 'to the punch body 14'. Designing the cube surface 16c 'as such a significant area and / or as the single contact surface of the lower area of the cube 16a' allows the punch point 16 'to be flexible in terms of its adaptability to diverge wedge member configurations employed by wide varieties of puncture bodies (and corresponding puncture frames).
[0089] In certain embodiments, the cube surface 16c 'is flat and has an inclination to 1 in relation to the lateral area of cube 18b'. By configuring the hub surface 16c 'to tilt diagonally inward from such a lateral hub area 18b', the way in which the engaging members (such as the wedge members 50 ') can alternatively slide inward (and opposing such a surface 16c ') and sliding outward (and becoming free of the cube surface 16c') by releasing the punch point 16 'is enhanced. Consequently, the general ease ■ by which the puncture point 16 'can alternatively be secured or released from the puncture body 14' is improved. With continued reference to Figure 3C, in certain embodiments, the single cube surface 16c 'is configured to come into contact (or move out of contact with) a corresponding single surface of the wedge members 50'. As shown, the single surface of the wedge members 50 'used in contact with the punch tip surface 16c' is the 50dd side 50d 'surface. Minimizing it: if the number of tip surfaces 16 'and wedge members 50' that are configured to contact them, there is less risk of misalignment between them, as is often the case with groups of contact surfaces. As further illustrated in Figure 3C, the surface 50dd 'has an inclination somewhat similar to that of the cube surface 16c', and such similarity allows for easier contact and manipulation between them (as described above in reference to Figures 1B and 1K to 1M ). It is natural to assume that an ideal design would be for such: sliding surfaces (that is, the cube and wedge member surfaces 16c 'and 50dd') to have the same angle of inclination. However, after careful analysis ,; it was found that this is not the case for the project incorporated into this document.
[0090] Although it is true that a very: large deviation of inclination angle between the puncture point surface 16c 'and the wedge member surface 50dd' is found to decrease the holding force between them, configure the surfaces 16c 'and 50dd' to have substantially the same or near tilt angle (for example, diverge mostly by one degree) significantly increased the difficulty involved with its manufacture. Not only that, but dictating that the contact surfaces 16c 'and 50dd' are substantially the same or almost the same is contrary to the objective described above for setting the punch point 16 'to be universal in its application in relation to various types of puncture frame. As mentioned above, not all puncture bodies can incorporate the exact wedge member design (or all 'wedge members) as provided with the puncture body 14'. Configuring the cube surface 16c 'to be flat and inclined allows the puncture tip cube 16a' of the puncture tip 16 'to exhibit satisfactory holding force without requiring that the surface 16c' matches exactly the corresponding body retaining members of puncture oü inside it. Consequently, the 16 "punch tip is more applicable to a wider variety of punch frames.
[0091] When determining working angles for each of the punch tip surface 16c 'and the wedge member surface 50dd', a wide variety of angle combinations were considered. Regarding the angles considered, they could be measured from a separate surface of the wedge member 50 '. > For example, with reference to Figure 1B and the wedge member 50 'illustrated therein, the flat surface 50c' of the wedge member side 50c could be the reference surface, of which various combinations of inclination angle for the surfaces '16c' and 5 Odd 'could be measured and then tested. As will be appreciated, due to the fact that the wedge members 50 'are moved into the recess 16b' of the punch tip hub 16a ', the punch tip surface 16c' is generally a smaller angle from such a reference surface 50c 'then the 50dd wedge member surface'. Consequently, the angles measured and tested for the puncture point surface 16c 'were smaller than the corresponding angles for the wedge member surface 50dd'.
[0092] In certain modalities, it was found that advantageous working angles, both for holding force and for maneuverability, for; puncture point hub surfaces 16c 'range from about 25 ° to about 55 °, while corresponding advantageous working angles <for the 50dd wedge member surface have been found to range from about 28 ° to about 60 ° °. ; Additionally, in certain modalities, it was found that the difference in angle of inclination between surfaces 50dd 'and 16c', which was found to be advantageous, both for sufficient holding force and for machining purposes, varies from about 2 ° to about 20 °. In preferential modalities, it was found that the difference in inclination: between the surfaces 50dd 'and 16c' is more advantageous when it is in the range of about 5 ° to about 10 °, and more preferable, when it is about 8 °. Referring to the working angles for the punch tip surface 16c ', in preferred modalities, the working angles found: to be more advantageous they were in the range of about 37 ° to about 50 °, and it was found that the corresponding working angles for the wedge member surface 50dd 'are most advantageous in the range of about 43 ° to about 56 °. In more preferred embodiments, it has been found that the working angle for the puncture point surface 16c 'is more advantageous when about 40 °, with the corresponding working angle for the wedge member surface 50dd' being found more advantageous when about 48 °.
[0093] The modalities in focus above involved coupling the punch tips 16, 16 ', and 16 ", and specifically their punch tip hub surfaces 16c, 16c', and 16c", with corresponding surfaces of wedge members for alternatively hold or release the puncture tips 16, 16 ', and 16 "to the puncture bodies: corresponding to puncture frames. However, it should be appreciated that a variety of movable bodies (ie in addition to the wedge members) can be used in puncture body designs to come into contact with puncture tip cubes when attaching puncture tips to puncture bodies, for example, in certain embodiments, moving bodies may involve balls or keys, however, given the adaptability of the cube design incorporated above, the punch points 16, 16 ', and .16 "have a greater chance of applicability in such cases.
[0094] Again, reference is made below specifically to the puncture tip 16 ', yet this description applies equally to the puncture tips 16 and 16 "with their similar hub features. In certain embodiments, the puncture tip 16' involves only a single contact surface 16c 'from hub 16a' to secure and release the punch tip 16 '. As described further, in certain embodiments, the hub contact surface 16c' is configured to be of an inclination angle that offers coupling of sound without the need for the corresponding contact surface 50dd 'of wedge members 50' to be of the same inclination angle, thus the sound coupling between hub 16a 'and moving bodies (such as wedge members 50' ) of a puncture body can be achieved by minimized contact surfaces between them, by also allowing the variation in inclination between the contact surfaces. combines the 16 'puncture tip incorporated to be applicable with a wide variety of puncture frame designs with modification limited to your designs and correspondingly reduced impact of manufacturing costs.
[0095] In the puncture body modalities that: incorporate the ancillary components described in this document, for example, the puncture body 14, determined by the components serves as triggers (for example, the meat 34, the loader body 36, and the wedge members 50) to ■ secure and release the punch tip 16 in relation to the punch body 14. The use of the cam 34 also improves the ease (by rotating the cam 34) by which an operator can easily manipulate and selectively other of the ancillary components to secure or release the puncture tip 16 in relation to the puncture body 14.
[0096] It is also known that the puncture tips for puncture frames are in a wide variety of sizes, types, and configurations. Figures 2A and 2B show perspective views of the puncture tip 16 ', and as: described above, it is similar to the puncture tip 16, but because it has a different tip size or projection (that is, with the tip 16' and its working end 16d 'being both narrower and more correspondingly elongated). As additionally alluded to above, Figure 2C shows another punch point 16 ", similar to punch point 16, still having certain distinctions according to certain modalities of the invention. For example, a distinguishing feature involves the upper surface 16e" of the hub 16a "being defined with a threaded portion 16f. As will be appreciated, the threaded portion 16f 'serves as an alternative coupling means for hub 16" in the case of punching bodies that do not employ wedge members (such as wedge members) 50). As mentioned above, in certain embodiments, the punch point 16 "is configured to be attached to punch bodies that use wedge members to lock / release the punch tip hub 16a. However, the threaded portion 16f allows the puncture point 16 "is alternatively attached to puncture bodies that do not employ such wedge members. In such a case, the punch body may have a threaded male portion which, when threaded on the threaded female portion 16f of hub 16a ", allows the punch point 16" to be secured with such a punch body. As shown, threaded portion 16f comprises a female thread defined within hub 16a "; however, it should be appreciated that hub 16a" may alternatively include a threaded male portion protruding from its hub 16a "that can be coupled with a corresponding threaded female portion defined with the puncture body.
[0097] Referring to the puncture tip 16 'of Figures 2A and 2B, the puncture body 14 1 (shown in Figure 3A) to which it corresponds has a narrow central cavity 38'. Figure 3B illustrates the punch tip 16 'that is attached to such punch body 14' in lateral cross-sectional view, according to certain embodiments of the invention. Also shown are ancillary components ■ similar to those described above in relation to the punch body 14 and punch tip 16, involving the cam 34 '(incorporated in Figures 3D and 3E), loader body 36' (incorporated in Figures 3F and 3G ), springs 42 ', 44', and 46 ', pusher-retainers 48', and wedge members 50 '. To that end, such components have similar uses and functions when attaching and releasing the puncture tip 16 'to the puncture body 14'. This is possibly best seen from Figure 3C, which shows an enlarged partial view of the ancillary components and their use when attaching the puncture tip 16 'to the puncture body 14'. As described above, despite the elongated and narrow configurations of the punch tip 16 'and punch body 14', there is little correspondence restriction in the designs of the punch tip hub 16a 'and the wedge members 50'.
[0098] Similar to what has already been described in relation to the puncture body 14, the puncture tip 16, and the ancillary components used with it, the meat 34 'is configured for rotation once positioned within the puncture body opening. 30'and the loader body hole 40 '. In certain embodiments, the permissible range of the rotating cam is dictated by the longitudinal extension of channel 60 ', as a ball 56' (of similar structure and function to ball 56 described above) retained within channel 60 'prevents further rotation do carne. In certain additional embodiments, the channel 60 'is formed with one or more pockets 60b' in which each serves as a rotatable locking position for the ball 56 ', and the cam 34' within the loader body orifice 40 '. For example, in certain embodiments, the locking positions include a first position which allows the puncture tip 16 * to be attached to the puncture body 14 '(in which the projecting portion 54aaa is oriented towards the front end 36a' of the puncture body loader 36 ') and a second position that allows the punch tip 16' to be released (or inserted into) the punch body 14 '(in which the projecting portion 54aaa is oriented towards the rear end 36b1 of the loader body 36 '). Referring to Figure 3C, and as further described below, even if the punch body 14 'and punch tip 16 (as well as the hub 16a thereof) are elongated, there is little matching effect when configuring the contact hub and surfaces wedge as already detailed above in relation to the hub and wedge member surface 16c and 50d' of the punch tip 16 and wedge members 50.
[0099] Similar to what was described above for the loader body 36 used with the punch body 14 and the punch tip 16, the opposite movements of the loader body 36 '(alternatively triggered by the rotation of the cam) serve as additional triggers for additionally secure or release the punch tip 16 'in relation to the punch body 14'. As described above, this additional firing involves the 50 'wedge members. In certain embodiments, and with reference to Figures 3B and 3C, a plurality of the wedge members 50 'is used with the loader body 36', with slits 36d 'in it to accommodate the members 50' accordingly. In certain embodiments, there are at least two wedge members 50 ', with each adapted to slide into one of the corresponding slots 36d' of the loader body 36 '. In certain embodiments, as shown in Figures 3F and 3G, the slits 36d 'are at the front end 36a' of the loader body 36 ', and are generally defined equidistant around the outer surface thereof. Figures 3C, 3H, 31, and 3J are seen in cross section of the punch body 14 ', showing different rotated positions of the cam 36' and the corresponding effects on the loader body 36 'and the wedge members 50', according to certain embodiments of the invention. As further detailed below, with movement of the loader body 36 '(by rotating the cam 34'), the wedge members 50 'are moved correspondingly with respect to the loader body slots 36d' and grooves 14b 'of the puncture body 14 '(which are external to the slits 36d'). As will be appreciated, the clamping and release processes in relation to the puncture body 14 'and its ancillary components are similar to the corresponding processes already described above in relation to the puncture body 14 and its ancillary components.
[00100] For example, starting with Figure 3H, the punch body 14 'is shown without the punch tip 16', with the meat 34 1 being partially inserted into the punch body opening 30 'and the loader body hole. 40 '. As described above, in certain embodiments, the punch body 14 'is configured to be operationally coupled with the meat 34' through a ball and channel connection. No such connection is still applicable as shown due to the fact that the head portion 52 'of the meat 34' is not yet completely within the punch body opening 30 '. In addition, none of the protruding portions 56aaa, 56bbb of the meat segments 56aa, 56bb are visible. For this purpose, in certain embodiments, the loader body orifice 40 'is defined to allow only the insertion of the meat 34' in it, if its projecting portions 56aaa, 56bb are oriented generally perpendicular to the 'front' end 14a 'of the puncture body. Consequently, there is no force from the cam 34 'being directed to the loader body 36', and little corresponding force from the loader body 36 'to the wedge members 50'. As such, the wedge members 50 ', when accommodated by the loader body slots 36d', are free to slide into the central cavity 36c 'of the loader body 36' (as shown).
[00101] In relation to Figure 31, again, the punch body 14 'is shown without the punch tip 16'; however, cam 34 'is shown to be completely inserted into the punch body opening 30' and magazine body hole 40 '. As such, in modalities that employ the sphere and channel type connection described above the punch body 14 'and flesh 34', the ball 56 '(not visible as it is positioned facing behind the head portion of meat 52 ') is not only located in channel 60', but also in one of the pockets 60b 'to lock meat 34' in position »As shown, spring 42 'resiliently deflects head portion 52' of meat 34 so as to keep the ball in such a pocket 60b 'and the meat 34' in such a rotated position. In particular, the illustrated position is to release / insert the punch tip 16 'in relation to the punch body 14'. In such a position, the projecting portion 54aaa of segment 54aa is oriented towards the rear end 36b 'of the loader body 36' which, in turn, forces the body 36 'inward (i.e. more deeply inward) of the' central puncture body cavity 38 '. Such pull into the loader body 36 ', in turn, allows the wedge members 50' to be pulled inward through their accommodation by the loader body slots; 36d '. As such, the wedge members 50 'are pulled adjacent to the grooves 14b' of the punch body 14 '. Such pull into the wedge members 50 'along with the outward force of the pusher-retainer 48' (by means of its spring 46 ') results in the pusher-retainer 48' coming into contact and forcing the members 50 'further out through from the loader body slots 36d 'and grooves 14b'.
[00102] Looking at Figure 3J, the puncture tip 16 'is shown to be partially inserted in the central cavity 38' of the puncture body 14'. Similar to what is shown in Figure 3H, the cam 34 'is completely inserted into the punch body opening 30' and the magazine body hole 40 '; however, its front end 34b 'is shown to extend outside the punch body opening 30'. Thus, in modalities that employ the connection of the sphere and channel type described above the puncture body 14 * and flesh 34 ', the ball 56' (again not visible as it is positioned facing behind the head portion of meat 52 ') is located in channel 60' and not in one of the pockets 60b 'to lock meat 34' in position. As shown, cam 34 'is rotated so that none of its projecting portions 54aaa, 54bbb are visible. In particular, portions 54aaa, 54bbb are generally perpendicular to the front end 14a 'of the puncture body, still oriented 180 degrees from its orientations described in relation to Figure 3H. Consequently, referring to Figure 3J, the inwardly directed force applied to the loader body 36 'is removed, resulting in the loader body being pushed outward (i.e., towards the front end 14a' of the punch body 14 ' ) through the action of spring 44 '. Such a push out of the loader body 36 'in turn forces the wedge members 50' to be pulled out through their accommodation by the loader body slots 36d '. In particular, the wedge members 50 'come into contact with the front and side surfaces 64' of the grooves 14b 'of the punch body 14'. Such pull out of »the wedge members 50 '(by means of the loader body 36') in combination with the inclination of the front and side surfaces 64 'of the grooves 14b' results in the wedge members 50 'sliding along such surfaces 64 ', back through the loader body slots 36d' and in the central cavity 36c 'of the loader body 36'.
[00103] Finally, with reference to Figure 3C (and Figure 3B), the punch body 14 'is shown with the punch tip 16' attached to it. Using the sphere and channel type connection described above the puncture body 14 'and meat 34', and similar to that described in Figure 31, sphere 56 'is located in another of the pockets 60b' to lock the meat 34 ' in position, with spring 42 'deflecting head portion 52' from cam 34 'so as to hold ball 56' in such pocket 60b 'and cam 34' is in such a rotated position. In particular, the illustrated position is to hold the punch tip 16 'in relation to the punch body 14'. In such a position, the projecting portion 54aaa of segment 54aa is oriented towards the front end 36a 'of the loader body 36' which, in turn, forces the body 36 'outward (i.e. shallower inside) of the central cavity puncture body 38 '.
[00104] Continuing from what was described above for Figure 3J, such a pull out of the loader body 36 'in turn forces the wedge members 50' to be pulled out further through their accommodation by the slits of 36d loader body. Such additional pull out of the wedge members 50 '(by means of the loader body 36') in combination with the inclination of the front and side surfaces 64 'of the grooves 14b'1 results in the wedge members 50' continuing to slide along of such surfaces 64 '. In particular, such a sliding action results in the wedge members 50 'passing further through the loader body slots 36d' in order to expose the coupling hub 16a 'of the punch tip 16' to secure the tip 16 'to the body of puncture 14 '. In further reference to Figure 3B, as the hub 16a 'of the punch tip 16' is inserted into the central punch body cavity 38 'and in turn, the central magazine body cavity 36c', additional movement inward it is prevented by contacting the front surface 16e 'of the hub 16a' with a rim 62 'which protrudes from the central cavity 36c' of the loader body 36 '. As described, the bead 62 'may involve an insertion ring 62' or a plurality of projections extending inwardly relative to the central cavity 36c '. In turn, the cam 34 'is rotated as described above, with the wedge members 50' locking the hub 16a 'from its rear.
[00105] As described above, the contact surfaces; for the punch tip hub 14a 'and the wedge members 50' can be configured similarly to those detailed above in relation to the contact surfaces 16c and 50d 'of the puncture point 16a and wedge members II 50. For this purpose, reference can be made to Figures II and 1J and the corresponding description above in relation to the contact and side surfaces of the wedge members 50 '.' For corresponding illustration in relation to the punch body 14 'and the punch tip 16' for the description referred to above, reference can be made to Figure 3C. Thus, even in cases of puncture assemblies that have a similar style to the puncture frame 10, but which accommodate puncture bodies of different dimensions (such as the puncture body 14 '), the puncture point design incorporated in this document (in relation to the characteristics of the puncture tip 16) remains applicable.
[00106] The testing of the puncture tip design has been further expanded to other styles of puncture body, however adapted to use the same 16 or 16 'puncture tips as described above. Figures 4A and 4B illustrate such an exemplary punch body, i.e., for a non-tower or Trumpf style punch frame, according to certain embodiments of the invention. Looking at: I the enlarged frame view of Figure 4A, the punch body 14 "is configured for use with the punch tip 16 'of Figures 2A and 2B. In certain embodiments, as shown in Figures 4A and 4B, ancillary components ( for example, meat 34 ", loader body 36", springs 42 ", 44", and 4 6 ", pusher-retainer 48", and wedge members 50 ") similar to those detailed above with respect to Figures 3A-3J are used with the puncture body 14 ". Based on this, the corresponding puncture tip 16 '(as shown in Figures 4A I and 4B) is alternately secured and released in relation to such a puncture body 14" following the same procedures described above in relation to Figures 3C, 3H, 31, and 3J, and using the same characteristics for the contact surfaces of the puncture point pub 16a 'and the wedge surfaces 50d'. Thus, even in cases of puncture frames that use different styles of puncture bodies than the puncture bodies 14 or 14 'incorporated in this document, as long as the frames are configured similarly to one of the puncture bodies 14 or 14' (in order to use ancillary components "similar" to them), the puncture point design incorporated in this document (in relation to the characteristics of puncture points 16 and 16 ') remains applicable.
[00107] The test of the puncture tip design has been further expanded to other puncture jig body configurations, 'however adapted to use the same puncture tips 16 or 16' as described above. Figures 5A and 5B show a magazine body for such an exemplary punching body, according to certain embodiments of the invention. Looking at Figure 5A, the loader body 36 "'is shown; with adjustment to hold a puncture tip according to certain modalities of the invention, while Figure 5B shows q loader body 36"' with adjustment to release the tip. puncture according to certain embodiments of the invention. As illustrated, in certain embodiments, the ancillary components1 used with the 36 "'loader body include different variations of meat 34"', spring 46 "'(shown in Figure 5B), pusher-retainer 48"' and wedge members 50 ". Unlike the loader bodies 36 and 36 'already described above, the loader body 36"' works with 50 "wedge members that are rigidly coupled to the body 36" '. As shown, in certain embodiments, such rigid fixation involves an arm 70 that extends between the loader body 36 "'and each of the wedge members 50". While the arms 70 provide a rigid positioning of the 50 "wedge members in relation to the loader body 36" ', the arms 70 are also configured to project outwards (as shown in Figure 5B), particularly when the pusher-retainer 48 '"is released in order to contact the 50 wedge members".
[00108] In certain embodiments, as shown in Figure 5A, the pusher-retainer 48 "'is locked in an inward position relative to the central cavity 36c" "of the loader body 36"'. In certain embodiments, pusher movement -retainer 48 '"is fired by rotating the cam 34'". Starting with Figure 5B, cam 34 "', when rotated in hole 40"' to a first position, triggers a release of the pusher-retainer 48 " '. In turn, the pusher-retainer 48 "'is propelled outward (ie away from the rear end 36b'") of the loader body 36 "'by means of the action of spring 44"' positioned behind the pusher-retainer 48 "'. With such an outward movement, p. The pusher-retainer 48"' comes into contact with the 50 "wedge members, causing them to protrude outward, for example, usually in a perpendicular direction I in with respect to the longitudinal C axis of the loader body 36 "'. Such a projection out of the 50 "wedge members allows the punch tip hub portion (e.g., punch point hub 16a 'of Figures 2A and 2B) to be subsequently inserted into the central cavity of loader body 36c '"along geometry axis C with contact being made with the pusher-retainer 48"' in an inward direction with respect to cavity 36c '". Following the insertion of a puncture hub in the cavity 36c '"(and the positioning inside the pusher-retainer 48"' in such cavity 36c '"), the wedge members 50" project inwards towards the central cavity 36c' "in response (by means of arms 70 returning to their initial straightened orientation), thereby locking the puncture point hub 16a'in place. In turn, the meat 34" 'is rotated in hole 40 "' to a second position, triggering a locking Ido pusher-retainer 48 "'against the resilient inclination Ida spring 44" ".
[00109] In certain embodiments, as shown in Figures 5A and 5B, the wedge members 50 "involve a contact surface of a different shape 50dd" in relation to the corresponding surface 16c 'of the punch tip hub 16a'. Figures 5C and 5D show perspective and side views of one of the 50 "wedge members, according to certain embodiments of the invention. As described above, the pusher-retainer 48" 'is configured to come into contact with the wedge members 50 "when released in order to urge the 50" wedge members in an outward direction I in relation to the central cavity 36c '". Taking this into account, the outward movement of the pusher-retainer 48"' may be adversely affected ( that is, it can get stuck) by the corresponding surfaces 50dd "if defined with edges. As such, in certain embodiments, the surface 50dd" of the wedge members 50 "is curved so that the pusher-retainer 4 8 '" upon its contact with the wedge members 50 "can slide freely along such surfaces ■ wedge member 50dd". Such curved surface 50dd "also works in sufficiently retaining the hub surfaces 16c 'to secure the punch tip 16' with the puncture body 14 "'. As described above, the punch tip hub 16a 'is configured to provide secure coupling even with difference in inclination angle (for example, in the range of about 2 ° to about 15 °) between the contact surfaces of the. puncture point 16a 'and the 50 "wedge member. As a matter of fact, the curved shape of the 50dd "wedge member surfaces does not present a problem. Thus, even in cases of puncture frames that use different puncture body configurations, in order to work with correspondingly different carrier bodies I (such as the loader body 36 "') than the loader bodies 36 or 36' incorporated in this document, the punch tip design incorporated in this document (in relation to the characteristics of the punch tips 16 and 16 ') remains applicable.
[00110] The testing of the puncture tip design has also been expanded to puncture bodies that use certain modifications and / or variations in relation to the components' already described in this document. For example, the ancillary components have been exemplified in this document as being initially triggered using an additional tool (such as an alien or torx wrench), in order to hold or alternatively release the puncture tips in relation to the puncture bodies. However, other punching frames, using different sets of ancillary components, may not require the use of such additional tools.
[00111] Figure 6A is a perspective view of a puncture body 14 "", the puncture tip 16 'of I Figures 2A and 2B and the ancillary components of an additional puncture frame, shown in an enlarged frame view , according to certain embodiments of the invention. As shown, such a punch body 14 "" includes a meat 72 for, (initially firing another of the ancillary components to alternatively secure or release the punch point 16 'in relation to the punch body 14 "". For example, the other components ancillary to the punch body 14 "" includes a plurality of balls 74, a carrier body 36 "", a plurality of springs 44 "" and 46 "", a pusher-retainer 48 "", and a plurality of members wedge 50 '(similar to those described with reference to Figures 3A to 3J).
[00112] As shown, in certain modalities; the meat 72 includes two curved partial portions 72a and 72b, which are configured to couple together to form a ring that has varying segments of thickness around its circumference. The cam 72 is configured to rest on a corresponding channel 76 defined around the circumference of the puncture body. Similar to the meats 34 and 34 'described above, the meat 72, in certain modalities, is rotatable to differ locking positions, which correspond to positions to alternatively secure or release the puncture point 16' in relation to the puncture body 14 "" . However, unlike meat 34 and 34 ', meat 72 is rotatable by hand (and without the use of any additional tools). Figures 6B to 6D show partial lateral cross-sectional views of the punch body 14 "" and the ancillary components, and how the components are located in the grip or release alternatively the punch tip 16 '. The cam 72 is configured to alternatively seat first and second balls 74 'and 74 "in depressions 78 located on opposite surfaces of a rod 80 of the loader body 36"'. As further detailed below, the corresponding movement of the loader body 36 "" depends on which of the first ball 74 'or the second ball 74 "(i.e. any ball 74', 74") is seated. For this purpose, however for use of the meat 72 as the initial firing medium, the steps through which the puncture tip 16 'is alternatively secured or released in relation to the puncture body 14 "" (as detailed below) involve variations in steps already described in this document with reference to Figures 3B, 3H, 31, and 3J.
[00113] Regarding Figure 6B, the punch body 14 "" is shown without the punch tip 16 '. The meat 72 is coupled to the punch body 14 "", coming into contact with each of the balls 74 with a different thickness from the meat 72. As shown, a greater thickness of the meat 72 comes into contact with the first ball 74 'as a lesser thickness of the meat 72 contacts the second ball 74 ". As shown, in certain embodiments, the depressions 78 in the loader body rod 80 are defined in different lengths from a first end 80a of the rod 80. In certain embodiments, the depression 78 corresponding to the first sphere 74 'is defined at an additional distance from such rod end 80a, then the depression 78 corresponding to the second sphere 74 ". Thus, when the first ball 74 'is seated, the carrier body 36 "" is pushed inward (i.e., away from the front end puncture body 14a ""), while, when the second ball 74 "is seated, the loader body 36 "" is pushed outward (that is, towards the front end puncture body 14a ""). The position of the loader body 36 "" shown in Figure 6B is to release (or insert) the tip puncture 16 'in relation to the puncture body 14 "". In such a position, the first ball 74' is locked in its corresponding depression 78, which in turn forces the body 36 "" inwards (that is, more deep) of the central puncture body cavity 38 "". The push into the loader body 36 "", in turn, forces the wedge members 50 'to be pulled in through their accommodation by slits 36d " "of the loader body 36" ". In particular, the wedge members 50 'are pulled adjacent to the grooves 14b" "of the punch body 14" ". a within the wedge members 50 'together with a force out of the pusher-retainer 48 "” (by means of its spring 46 "") results in the pusher-retainer; i 48 "" contacting and forcing the members 50 'further out through the loader body slots 3 6d "" and into the grooves 14b' ". However, as shown,} additionally, the movement out of the pusher -retainer • 48 "" is limited by contact with a flange (for example, insertion ring 62 "") extending inwardly in relation to the central cavity 36c "" of the loader body i 36 "".
[00114] Looking at Figure 6C, the meat 72 is} rotated so that smaller thicknesses of the meat 72 are. > positioned adjacent to each of the first and second spheres 74 'and 74 ". Therefore, none of the spheres« 74', 74 "is seated in their corresponding depression 78 da; loader body rod 80. Continuing from Figure 6B, spring 44 "" further impels loader body 36 "" in an outward direction relative to the body; punch 14 "" (that is, towards the front end 14a "" of the same). Such an impulse out of the loader body 36 "", in turn, causes the wedge members 50 'to be similarly pulled out through} their accommodation by the loader body slots 36d "". In particular, the wedge members 50 'are moved against the front side surfaces 64 "" of the grooves 14b "" of the punch body 14 "". Pulling out the wedge members 50 '(via the loader body 36 "") in combination with the slope of the front side surfaces 64 "" of the grooves 14b "" results in the wedge members 50' sliding along i such surfaces 64 "", back through the slots of the loader body 36d "" and in the central cavity 36c "" of the loader body 36 "". However, the wedge members 50's are prevented from sliding too far taking into account the contact that is made with the outer sides of the pusher-retainer 48 "”. As shown in Figure 6C, the punch tip 16 'is shown as starting to be inserted into the central cavity 38 "" of the punch body 14 "" and can be additionally inserted until the punch tip hub 16a 'passes through the wedge members 50' and faces the protruding rim of the loader body 36 "".
[00115] Finally, with reference to Figure 6D, the puncture body 14 "'is shown with the puncture tip 16"' attached to it. Following the insertion of the punch tip cube 16a 'in the central cavity of the punch body 38 "", the cam 72 is rotated in position so that a greater thickness of cam 72 contacts the second ball 74 "while a thickness smaller of the meat 72 comes into contact with the first ball 74 '. In such a position, the second ball 74 "is locked in its corresponding depression 78. Continuing from what was described above for Figure 6C, the locking of the second ball 74 ", in turn, locks the wedge members 50 'from being pulled further into the puncture body grooves 14b" "due to their accommodation with the loader body slots 36d" "and their contact with the sloping surfaces 64 "" of the puncture body grooves 14b ".
[00116] As should be noted, the design of the punch body illustrated in Figures 6A to 6D has little impact on the configuration of the contact surfaces for the punch tip hub 14a "" and the wedge members 50 '. As such, these surfaces can be configured similarly to those detailed above with respect to contact surfaces 16c 'and 50d' of the punch tip hub 16a 'and wedge members 50'. For this purpose, reference can be made again to Figure IB and the corresponding description above in relation to the configuration and contact surface of the punch tip hub 16a '. Additionally, reference can be made to Figures II and 1J and the corresponding description above in relation to the contact and side surfaces 50d 'of the wedge members 50'. In addition, the workable angle ranges and preferred angles described above (as found favorable for the contact surfaces 16c and 50d 'of the punch tip 16 and wedge members 50) can apply equally to the cube and wedge member surfaces 16c 'e 50d' in relation to the puncture tip 16 'and the wedge members 50', regardless of the narrow and elongated shapes of the puncture body 14 'and the puncture tip 16'. Thus, even in cases of puncture frames that have different mechanisms for firing, the design of the puncture tip incorporated in this document (in relation to the characteristics of the puncture tip 16) remains applicable.
[00117] Figures 7A and 7B are perspective and side views of an additional exemplary 50 "wedge member, according to certain embodiments of the invention. As described above with reference to Figures 5A to 5D, the surface of wedge members in contact with the puncture point hub in puncture frames can be curved In certain embodiments, the wedge members used with puncture bodies to secure / release the puncture point design incorporated in this document may have entirely external lateral surfaces round, as exemplified with the 50 "wedge member.
[00118] Figure 8 is a flow chart of steps for attaching a puncture tip to a puncture body for a puncture frame, according to certain embodiments of the invention. It should be noted that the flowchart can refer to the puncture bodies and puncture tips illustrated in any of Figures TB, 3B, 4B and 6B in this document. However, the steps of the flowchart are described by way of example with reference to the puncture body 14, the puncture tip 16 and the ancillary components shown in Figure 1B.
[00119] Step 82 involves initially providing a puncture body 14 and a plurality of ancillary components used with it. Similar to that already described above, the punch body 14 has a side wall 32 that defines a central cavity 38, which extends along a longitudinal extension of the punch body 14. The plurality of ancillary components includes a flesh 34, a body loader 36 and a plurality of wedge members 50. Loader body 36 is seated in the central puncture body cavity 38, with the cam 34 coupling the puncture body 14 and the loader body 36 via hole 40 and of the aligned opening 30.
[00120] Step 84 involves adjusting the meat 34 in a second position (which corresponds to that shown in Figures IL and ILL). The cam 34 in said second position corresponds to the loader body 36 being lowered in position in the central puncture body cavity 38 and to each of the wedge members 50 being unlocked in the central puncture body cavity 38. The unlocked position of the members wedge 50 corresponds to a puncture configuration of the punch body 14 in relation to a punch tip 16. Step 86 involves confining a punch tip 16 with the punch body 14. The punch tip 16 includes a hub 16a in an end thereof, where the hub 16a is inserted into the central cavity 38 of the punch body 14.
[00121] Step 88 involves adjusting the meat in a first position (which corresponds to that shown in Figure 1B) which corresponds to the loader body 36 being raised in position in the central puncture body cavity 38 and to each of the wedge members 50 being locked in the central cavity of the punch body 38. The locked position of the wedge members 50 corresponds to a locking configuration of the punch body 14 in relation to the punch tip hub 16a.
[00122] In the previous detailed description, the invention has been described with reference to specific modalities. However, it should be noted that various modifications and changes can be made without departing from the scope of the invention as defined in the attached claims.
