    TABLE FOR A PRESSING DEVICE
    The present invention relates to an attachment for a manually or motor-driven, hand-held pressing device, wherein the attachment comprises a base body and two rotatably mounted thereon levers, which are actuated by the pressing device, according to the preamble of claim 1.
    STATE OF THE ART
    Manual or motor driven, hand-held pressing devices are used with attachments. Different attachments can be used. In the construction of houses or in the renovation of flats and houses, attachments are used for said pressing devices with which one can press fittings (pipes) together. A pressing device with a fitting for pressing fittings is also referred to as a fitting press machine or Fittingpresszange. Since they are used in house construction, they represent a standard tool for installers, for example. Fitting press machine and Fittingpresszange each consist, as mentioned, of a pressing device and a top, wherein the pressing device actuates the attachment. In the case of the fitting press machine, this is motor-driven and driven manually in the case of the Fittingpresszange. The principle is the same in both cases, the pressing device actuated, motorized or manually, two levers of the essay, which are arranged rotatably mounted on a base body of the essay. The article also has elements which, controlled by the levers, press the pipes to be pressed. For walls, in particular plasterboard walls, an elevation is often used. In this case, U-shaped metal posts between the floor and ceiling are often mounted in cross-section and wall plates, such as plasterboard, attached, which form the wall in a row.
    To be able to lay all kinds of lines in the walls, it is necessary to create through holes in the uprights. This often happens inelegant and expensive with the help of a flex.
    This type of production of through holes not only has the disadvantage of being expensive, but also affects the stayer in terms of their stability. With the Flex, the cuts are often set uncontrollably and thereby too long cuts are produced, which affect the stability of the stayer.
    Another disadvantage is that the through holes often have sharp corners or edges at which people injure themselves or the durchzufädelnden lines can be damaged. Due to the sparking there is also a risk of fire.
    OBJECT OF THE INVENTION
    The aim of the present invention is therefore to avoid this disadvantage and to provide an attachment for pressing devices with which through-openings workpieces, preferably profile components or metal posts can be made easily and quickly. Furthermore, the
    Stability of the uprights should not be impaired and no sharp corners or edges should be created so that persons can not injure themselves and the lines to be threaded through can not be damaged.
    PRESENTATION OF THE INVENTION
    According to the invention, this is achieved in an attachment for a manually or motor-driven, hand-held pressing device, the attachment comprising a base body and two rotatably mounted levers which are actuatable by the pressing device, achieved in that the attachment a die and a punch comprising, which are arranged movable against each other along an actuating axis, and the levers are provided to drive the die and the punch, wherein the punch has a cutting edge and the die an abutment for cutting through holes in profile components, preferably metal stand.
    It has been found that the passage opening can be generated quickly and easily with the aid of the attachment according to the invention, whereby the stability of the metal posts is not impaired. In addition, the through hole has no sharp edges or corners where people can injure themselves or the cables to be laid can be damaged.
    Since the attachment according to the invention to all standard pressing devices, so in particular for
    Pressing devices of fitting press machines, it is particularly easy, the fitting press machine for cutting through holes in profile components, preferably
    To use metal stand, it only has to be replaced the essay.
    The die and the stamp are actuated by the levers in that they are moved towards each other by the levers and the pressure necessary for the cut is built up. The receiving space serves to receive the separated part of the post, which falls out of the receiving space after the divergence of die and punch or can be easily removed. The cutting edge is in the final position near the inner surface of the side wall comprising the receiving space, whereby the part of the post to be separated can be efficiently cut.
    In order to ensure a stable and simple guidance of the die and the punch, it is provided in a preferred embodiment of the attachment according to the invention that the die are arranged on a first and the punch on a second each movably mounted on the attachment carrier. The carriers may be square or cylindrical and their attachment to the die or stamp is preferably carried out interchangeably. It is understood by movably mounted, that the two carriers are attached to the body of the essay so that they can still move along the actuation axis against each other. Mounted may mean that the carriers are arranged displaceably at least in sections along the actuation axis in guide elements, or that they are movably arranged by means of bearings. Furthermore, it is provided that first and second carriers are each moved by one of the two levers in order to move the carriers towards and away from one another along the actuation axis. Actuation of the die and punch by the levers via the carrier is a particularly simple possibility. This gives the carriers the task of ensuring the correct guidance. What is attached to each of the two supports is variable and can also be subsequently changed.
    According to a further embodiment variant of the attachment according to the invention, it is provided that first and second carriers are each provided with a recess into which in each case a first end region of one of the two levers engages in order to move the carriers towards and away from one another along the actuation axis. This recess can be designed as a slot, in which the matching end portion of the lever is introduced. In this case, in the recess, a contact surface, which represents the contact between the lever and the carrier, bent about an axis orthogonal to the actuating axis and the associated part of the lever to be straight, or vice versa, whereby a good power transmission is provided. The lever can thus guide the movement of the wearer in the direction of the other wearer or even away from it.
    According to a further embodiment variant of the attachment according to the invention, it is provided that the levers of the pressing device can each be actuated in a second end region, wherein the second end region is arranged on a side of the levers opposite the first end region with respect to a rotatable mounting of each lever , Ideally, the contact surface at which the pressing device contacts the respective lever is bent or executed in the form of a curve. The shape of the bend defines the translation or the speed of rotation of the lever. This makes it possible to optimally transfer the force of the pressing device to the carrier and thus also subsequently to the die and the punch.
    In order to be able to control the movement of the two carriers most optimally, it is provided in a further embodiment variant of the attachment according to the invention that first and second carriers are each guided in a guide element arranged on the attachment. This guide element can be designed to be elongate along the actuating axis and have a recess corresponding to the recess of the respective lever.
    According to a further embodiment variant of the attachment according to the invention, it is provided that the first and second supports are each elongated, preferably cylindrical, wherein the longitudinal axes of the first and second support are each identical to the actuation axis. This means that the respective lever leads the first and second, elongated carrier along the actuating axis. The elongated shape allows good handling and storage and is thus easy and inexpensive to implement.
    According to a particularly preferred embodiment variant of the attachment according to the invention, it is provided that the die is arranged in an end region of the first and the punch facing the die in an end region of the second support facing the die. In this case, the die or the punch is arranged centrally on the respective carrier. This represents a particularly simple embodiment.
    According to a further embodiment variant of the attachment according to the invention, it is provided that the punch has a side wall enclosing the actuating axis with at least one edge facing the die, wherein the edge facing at least one of the die is designed as a cutting edge. In the direction of the actuating axis, the shape of the edge may have corners or be round, the shape defines the shape of the through holes to be cut in the profile components. Thus, the shape of the through holes can be made different. Because the edge is designed as a cutting edge, an easily manufactured and stable cutting edge is available.
    According to a further embodiment variant of the attachment according to the invention, it is provided that the die has a receiving space for receiving at least one cut-out part of the profile components, preferably metal posts. This receiving space is open on the side facing the stamp and serves to receive both the cut-out part of the profile components, as well as a part of the punch at the end of the cut. Therefore, according to a further embodiment variant of the attachment according to the invention, provision is made for the side wall of the stamp to project into the receiving space at least in sections in an end position in which the cutting edge has cut through the passage opening. Die and punch are thus cup-shaped and pushed into one another.
    According to a further embodiment variant of the attachment according to the invention, it is provided that the die has a side wall enclosing the actuation axis, which limits the receiving space normally to the actuation axis, the side wall having an end face facing the stamp, which forms the abutment of the die. The face of the sidewall is that part of the sidewall of the die which is closest to the die and faces. This end face of the side wall is applied to the profile components at the point to be cut and provides the abutment for the punch during the cut.
    In order to be able to guide the cutting edge close to the side wall, in a further embodiment variant of the attachment according to the invention it is provided that an inner surface of the side wall of the die is aligned parallel to the actuating axis.
    According to a further embodiment variant of the attachment according to the invention, it is provided that the cutting edge of the stamp has a closed circumference about the actuation axis. Thus, the cut-out part of the profile component can be completely removed. If the cutting edge of the punch is not closed around the actuating axis, the point where the cut was made must first be bent to the side in order to release the through hole.
    According to a further embodiment of the attachment according to the invention it is provided that all points of the cutting edge have the same distance to the inner surface of the side wall of the die, whereby the sheath has the same course as the side wall of the die and the distance can be preferably kept so low that the Profile components are kept stable during the cut.
    According to a further embodiment of the attachment according to the invention it is provided that the side wall of the die is rotationally symmetrical with respect to the actuating axis, which represents a particularly simple and cost-effective variant. For this reason, it is provided in a further embodiment of the article according to the invention that the side wall of the punch is formed in relation to the actuating axis is substantially rotationally symmetrical.
    According to a further embodiment variant of the attachment according to the invention, it is provided that the matrix is detachably arranged on the first and the punch is detachably arranged on the second support. It is conceivable that the stamp on the first and the die on the second carrier are each arranged screwed. The advantage is that different matrices and stamps can be used (for example with different diameters). The thread also serves to be able to quickly and easily unscrew a die or a stamp on the support or to be able to remove, so that different matrices, for example, for different hole sizes can be easily changed.
    In order to be able to generate a round passage opening, it is provided in a further embodiment variant of the attachment according to the invention that the cutting edge of the punch is rotationally symmetrical with respect to the actuation axis. This is a particularly easy to manufacture variant and the cut also creates no sharp edge.
    According to a further embodiment of the attachment according to the invention it is provided that the side wall of the punch has an outer surface which is tapered running to the actuating axis, wherein the distance of the outer surface decreases to the actuating axis with increasing distance to the die. It is understood by conical that an outer circumference of the rotationally symmetrical side wall, which is closer to the die, is greater than a farther removed. The circumference decreases with increasing distance to the matrix. If the front part of the punch, which comprises the cutting edge, penetrates into the receiving space of the die after cutting, then, as the punch is withdrawn, it does not become so easily wedged in the cut workpiece due to the conical outer shape of its side wall.
    According to a further embodiment variant of the attachment according to the invention, it is provided that one of the two supports has a guide extension which, upon actuation of the attachment between an actuation position, in which die and punches intersect the profile components, and reaches the end position in a guide opening of the other support provided for this purpose is. This guide extension is arranged centrally on the actuating axis, running elongated and thus displaceable with its longitudinal axis along the actuating axis. The guide extension protrudes into the spaced space between the die and punch in an initial position in which the levers have not yet been actuated by the pressing device and can be introduced into a predrilled hole in the profile component. Before the stamp contacts the profile component, the guide extension can already be introduced into the guide opening upon actuation. Thus, the stamp is given a guide and thus a lateral support at the time of the cut. It is conceivable to arrange the guide extension detachable.
    In order to enable an independent return of the die and punch from the end position, it is provided according to a further embodiment of the article according to the invention that a spring connecting these is attached to the two rotatably mounted levers, which exerts a pressure on the two levers in the end position, to be able to return the two rotatably mounted lever from the end position to a starting position in which the die and the stamp are spaced from each other. The nature of the spring is not critical, it can therefore be performed as a simple, slightly curved metal rod, which is inexpensive to manufacture the spring.
    According to a further embodiment variant of the attachment according to the invention, it is provided that on an outer surface of the side wall of the punch a stop ring enclosing it at least partially is arranged, which is present in the actuation position on the side facing the punch of the side wall of the die to the punch from the receiving space of the die to be able to push out or to push the stamp away from the die.
    It is therefore provided according to a further embodiment of the attachment according to the invention that the stop ring is arranged in a direction corresponding to the actuating axis displaceable on the outer surface of the side wall of the punch. By slidably understood that the stop ring can change its position relative to the outer surface of the side wall of the punch according to the direction of the actuating axis. Thus, a pressure can be built up at this point and make the cutting a clean cut. The slidable design allows sliding of the cutting edge into the receiving space of the die.
    According to a further embodiment of the attachment according to the invention it is provided that at least one Abdrückfeder is arranged on the punch, which connects the stop ring and the punch together and exerts a pressure in the direction corresponding to the actuating axis on punch and stop ring to move the stop ring in the direction of the die , Thus, after removal of the essay from the uprights of the stop ring can be independently brought back to its original position.
    According to a further embodiment variant of the attachment according to the invention, it is provided that the outer surface of the side wall of the punch has a stop edge and the stop ring has a stop lip associated with the stop edge in order to limit the movement of the stop ring in the direction of the die.
    According to a further embodiment variant of the attachment according to the invention, it is provided that the die has a region which is located at the bottom of the receiving space and rises in the direction of the punch, which partially bridges the receiving space in the direction corresponding to the actuating axis and which in the end position is in contact with the side wall of the punch partially overlapped with respect to the actuation axis in order to bend the part of the profile component cut off by the cutting edge, preferably metal posts. This area can be designed as a rotationally symmetrical wall about the actuation axis or as a central elevation. The cut part can be more easily removed from the receiving space as a result of its bending after the cut.

The article 1 has a base body 37, which is attachable to the pressing device. On the main body 37, two levers 3a, b are rotatably mounted, which are actuated by the pressing device. In addition, two guide elements 11a, b are arranged on the main body 37, which define an actuating axis 6 due to their longitudinal extent and in which a first 12a and second carrier 12b are guided along the actuating axis 6 against each other and from each other.
    First and second carrier 12a, b may be rotationally symmetrical or angular and each have a recess 26a, b for contacting by the lever 3a, b (see.
    Fig. 2). The two supports 12a, b each have an end region 13a or 13b, a die 4 being detachably secured in the end region 13a of the first support 12a and a die 5 in the end region 13b of the second support 12b.
    Both punch 5 and die 4 are connected in the present embodiment via a thread 14 a, 15 a and 14 b, 15 b with the respective carrier 12 a and 12 b. However, other releasable fasteners are also conceivable in order to be able to attach different shapes or sizes of punches or dies for cutting through openings of most different shape on the supports 12a, b.
    In detail, the die 4 has a preferably rotationally symmetrical side wall 8, which together with a bottom 38 forms a receiving space 7 (FIG. 1) which is open on its side facing the punch 5. The side wall 8 is rotationally symmetrical and preferably has an inner surface 32 which extends parallel to the actuating axis.
    The punch 5 also has a preferably rotationally symmetrical side wall 16, whereby also the cup-shaped punch 5 is not necessarily open on the side facing the die 4. An edge 24 of the die 4 facing side of the side wall 16 is formed by the die 4 side facing the side wall 16 and an outer surface 17 of the side wall 16. This edge 24 is formed as a preferably rotationally symmetric cutting edge 9, with the help of the passage openings in the profile components, preferably metal frames 2 can be cut. In the present case, the cutting edge 9 is formed in three parts, so that correct way actually provided three offset by 120 ° cutting. For the sake of clarity, however, in the subject description, only "the " Cutting edge 9 referenced.
    By fixing the die 4 and punch 5 on the first 12a and second support 12b, and along the actuating axis 6 movable storage of the support 12a, b in the respective guide element 11a, b, it is possible, die 4 and 5 punch each other and away from each other to move.
    An elevation 27 arranged in the receiving space 7 extends from the bottom 38 of the cup-shaped receiving space 7 in the direction of the punch 5.
    The outer surface 17 of the side wall 16 of the punch 5 is conically designed such that the circumference of the side wall 16 in the direction of the die 4, parallel to the actuating axis 6, increases and decreases in the reverse direction.
    On the outer surface 17 of the rotationally symmetrical side wall 16, a rotationally symmetrical side wall 16 comprehensive stop ring 22 is arranged. This stop ring 22 is also rotationally symmetrical and template 4 and 5 stamp against each other, so suggests the die 4 facing side of the stop ring 22 to a punch 5 facing end 25 of the side wall 8 of the die 4 to each other. In order to prevent falling of the stop ring 22, this has a stop edge 33 and the
    Outside surface 17 of the side wall 16 of the punch 5 on a stop lip 34, which overlap in the direction of the actuation axis 6. An abdrückfeder 23 arranged between the side wall 16 and stop ring 22 pushes the stop ring 22 in the direction of the die 4. However, this is only so far possible until the stop edge 33 abuts the stop lip 34.
    The stop ring 22 is movable along the actuating axis 6, whereby after abutment of the stop ring 22 on the side wall 8 of the part of the side wall 16 of the punch 5 with the cutting edge 9 can partially penetrate into the receiving space 7, wherein the Abdrückfeder 23 is tensioned.
    Each of the two levers 3a, b has a first end region 28, which is arranged on the side of the respective lever 3a, b facing the respectively closest carrier 12a, b, and a second, the first end region 28, with respect to the rotatable mounting 30 , opposite to the respective lever 3a, b arranged end portion 29, on which the pressing device engages.
    The first end region 28a engages in the recess 26a of the first support 12a and contacts it there, likewise the first end region 28b engages in the recess 26b of the second support 12b. In this case, in the recess 26a, b, a contact surface, which represents the contact between the lever 3a, b and support 12a, b. The associated part of the lever 3a, b is bent around an axis orthogonal to the actuating axis. The lever 3a, b can thus guide the movement of the carrier 12a, b in the direction of the other carrier 12a, b or else away from it. The power transmission from the lever 3a, b on the support 12a, b can also be done via a roller.
    Each of the two second end portions 29a, b is curved in the form of a curve to provide the pressing device in each position an ideal point of application.
    The mode of operation of the attachment 1 is the following: In an initial position 20, the die 4 and the punch 5 are spaced from one another, that is, there is a free space between the die 4 and the punch 5 (FIG. 1). The metal upright 2 (FIG. 1) is U-shaped in the plane of the drawing. The device is then applied with the die 4 on a surface of the metal upright 2.
    The levers 3a, b are now pressed apart from the pressing device in the second end regions 29a, b. In this case, the first end regions 28a, b of the levers 3a, b press the two carriers 12a, b toward one another along the actuation axis 6.
    The embodiment variant shown in FIGS. 1 to 4 additionally has a guide extension 18, which is not absolutely necessary for the function of the invention, and which is detachably arranged on the carrier 12a. In the metal upright 2 a pilot hole is mounted, in which the guide extension 18 can be inserted.
