354045505560121108 14o47sE 2the opposite outer edge of the salmon tail groove and thereby wedge the support body in a desired axial position inrelation to the base body. The cutting blade in turn is fixed in a desired axial position relativethe support body in the outer groove by means of a number of (usually at least three) clamping jaws,which applies an evenly distributed clamping force against an upper longitudinal edge along the blade, whereby across-sectional V-shaped lower longitudinal edge is pressed against an inclined, lower interface of the groove.
A troublesome disadvantage of previously known cutting tools of the type in question isthat changing inserts and / or knitting blades is cumbersome and time consuming, more precisely as a resultof the fact that the sticking blade is freely movable in the associated grooves in the support body as soon as they are holdingthe clamping jaws loose. This means that the exact, radial of the various cutting blades and insertsdistance from the pipe to be machined must be determined by manual measurement andfine adjustment of the axial position of the blade along the support body. In thatThe position accuracy of the inserts is in the order of 0.1 mm, it is easy to see that the work ofsetting the cutting blades in for example four tan gentily separated tools becomes tricky andtime consuming. In practice, thus, cutting changes or chores in connection with the adjustment ofthe machine for different pipe dimensions, take 1-2 hours. This should be compared with itnormal service life of the individual inserts, which is usually in the range of 10-15 minutes.
The setting times of the machine between periods of operational operation are thus disproportionately long, andentails significant costs.
Objects and features of the inventionThe present invention aims at eliminating the above-mentioned disadvantage ofpreviously known cutting tools and create an improved cutting tool. A primary purpose ofthe invention is therefore to create a cutting tool, the cutting blade of which can be disassembled andreassembled without the need for repeated measurements and fine adjustments of its axial position. Onefurther purpose is to streamline the exact position determination of the inserts in relation tothe center of the machine in connection with the occasions when the dimensions of the pipe or workpiecerequires adjustment of the tool or when other inserts and / or cutting blades need to be mounted inthe tool.
According to the invention, the above-mentioned objects are achieved by between the base body andthe support body is provided with an adjusting body which is actuated by a spring device, which strives todisplace the actuator axially relative to the base body, and against which action the actuator isfixable in a desired position relative to the base body by means of a screw connection, each blankthe cutting blade is fixed in a predetermined position in the groove of the support body by means of partly one657075808590121108 14o47sE 3stop means, partly a screw, which extends through a through hole in the knitting blade and istightened in a threaded hole, which opens into a bottom of the groove.
In one embodiment, the width of the groove between its boundary edges is greater than that of the knitting bladewidth between the two longitudinal edges, to allow assembly and disassembly of the knitting bladewith a side surface facing the bottom of the track. In this case, the through hole in the knitting blade has onekeyhole-like contour shape by including a circular section, the diameter of whichis larger than the diameter of a skull on the screw, partly an elongated section, which extends fromthe round section to an end surface, and has a width which is smaller than that of the screw headdiameter. In this way, disassembly of the blade is allowed by the simple action of unscrewingscrew a few turns and shift the blade so that the round section of the hole is alignedthe screw head, the latter being able to pass through the hole as the blade is taken out of the groove. OnConversely, the plug blade can be reassembled into the groove to retract after tightening the screwits exact radial position relative to the center of the machine.
In yet another embodiment, the cutting blade includes seats and cuts at both ends,wherein the keyhole includes two from a common, circular section running anddiametrically opposite, elongate sections, the end faces of which are located on one and the same axialdistance from a nearby seat resp. notch. In this way, the two inserts can changecarried out quickly and easily without their exact positioning in relation tomachine center is lost.
In another embodiment, the adjusting body of the holder comprises means for releasably receivinga protruding sensor with the task of determining the loosely made and spring-loadedthe position of the adjusting body relative to the base body depending on the distance to a workpiece. Sincethat the sensor is releasably connected to the adjusting body, the same can be done quickly and easilyremoved from the adjusting body after completion of the task, so as not to interfere withthe processing operation.
Summary of the inventive conceptThe invention is based on the idea of eliminating the need for measurement andfine-tune the knitting blade relative to the associated support body and instead ﬂ surface the required onethe setting function of an adjusting body arranged between the support body and the base body, irelation to which the support body assumes a fixed axial position as soon as the adjusting operationexecuted.95100105110115121108 14047SEBrief description of the accompanying drawingsPig.

Detailed description of a possible embodiment of the inventionIn Pig. 1 generally denotes a machine, by means of which a metal tube 2 oranother elongate, cylindrical substance can be cut, more precisely by a so-calledparting operation. In a front stand 3 included in the machine, a number is mountedperipherally spaced cutting tool 4 according to the invention. The example includes four in the machinetools, which are placed with 90 ° pitch. Each tool is associated with a not shownmatardon, e.g. a ball screw, by means of which the tools can be applied linearlyforward movements in the direction of the arrows P, i.e. towards (and from) a geometric center axis Cfor the machine. The front frame 3 includes a central opening 5, which is delimited by onecircumferential hollow edge surface 6, in relation to which the so-called knitting needles, which are included in the tools, canprotrude radially inwards towards the center axis C. Using a non-visiblerotor assembly, the tools can be set in rotation, more specifically in the direction of the arrow R.
Now refer to Pig. 2 showing how the individual tool 4, exceptstick blade 7, includes a holder designated in its entirety by 9, which is composed of threevarious main components, namely a base body 10, a support body 11, and an adjusting body 12.
The bodies 10, 11, 12 have a flat, parallelepipedic basic shape and therefore comecontinue to be referred to as "tiles". The knitting blade 7 also has the same basic shape, although thisis thinner than the plates.
Now refer to Pig. 4 and 5, which in summary illustrate those in the toolthe components were shown both from the front and from behind. The components are alsoillustrated separately in enlarged condition in Pig. 6-10, the selected perspective beingsame as in Pig. 4.
As shown in Pig. 4 and 5 in combination with Pig. 6, includes the base plateTwo plane-parallel surfaces 13, 14, which extend between two flat end surfaces 15, 16, and ofwhich one 13 forms a front side and the other 14 a back side. In addition, delimitedthe base plate 10 of two mutually parallel, upper and lower longitudinal edges 17, 18, which arecross-section V-shaped to guide the base plate linearly relative to a guide included in the machine framein connection with the reciprocating feed movements of the tool. These longitudinal edges 17, 18 arealso parallel to an imaginary geometric axis A, which defines an axial extent for both155160165170175180121108 14o47sE 6the base plate 10 as the tool holder 9 in its entirety. Adjacent to the end face 15 is in the front13 takes out a socket 19, which in addition to a flat bottom 20 is delimited by an end wall 21 and twoparallel side walls 22. The bottom 20 opens into four threaded holes 23. In the end wall 21 opensfurthermore a number of cylindrical seats 24. As can be seen from Fig. 5, a socket 25 is also recessed inthe back of the base plate 14. This socket has the task of receiving a coupling (not shown) toconnect the base plate to the feeder, which handles the feed movements of the tool.
As further shown in Figs. 6 and 7, a bottom plate 26 is fixedmounted in the socket 19, more precisely by being held against the bottom 20 by means offour pipe screws 27, which in addition to a head 28 partly comprise an external thread 29 fortightening in a cooperating hole 23, partly an internal thread (not visible). Bottom plate 26front consists of a so-called serration surface 30, of a kind including longitudinal ridges andgrooves with straight shape. The skulls 28 are recessed relative to the serration surface 30, thenthe pipe screws are tightened in the threaded holes 23.
The adjusting plate 12 (see Fig. 8 in combination with Figs. 4 and 5) includes fourelongated holes 31, which extend continuously between the front side 32 and the back side 33 of the plate.
The holes 31 are intended for fastening screws 34, the male threads of which can be tightened in the pipe screws 27female threads. These fastening screws 34 are provided with skulls 35, which are attachable to countersunkshoulder surfaces 36 in the holes 31. In one of two opposite, flat end surfaces 37, a cylindricalseat 38 for receiving a releasably mounted sensor 39, the function of which will bedescribed later. The back 33 of the adjusting plate 12 (see Fig. 5) has the form of a serration surface arrangedto cooperate with the serration surface 30 of the bottom plate 26. When the ridges in one serration surface gripinto the grooves in the other, a distinct rectilinear guide of the adjusting plate is obtained, as thisdisplaced axially relative to the base plate. An axial is formed in the front side 32 of the adjusting plate 12running ridge 40, the length of which may be greater than the length of the adjusting plate 12 itself. In the ridge's 40 back surface41 opens a seat 42 for a pin 43 with a conical, free end 44. In addition, two pairs extendthrough, threaded holes 45 between the front and backs of the adjusting plate. With the adjusting plate 12cooperates a spring device in the form of a lamella 46, and a plurality of compression springs 47, which act againstthe lamellae. More specifically, four helical springs are provided, which are mounted in themseats 24, which open into the end surface 21 of the housing 19. The spring device always strives to displacethe adjusting plate 12 in the direction of the end surface 15 of the base plate 10.
From Fig. 9 in combination with Figs. 4 and 5, it appears that the parallelepipedicthe support plate 11 comprises two plane-parallel surfaces 48, 49, of which the former forms a185190195200205210121108 14o47sE 7front and the latter a back. Otherwise, the support plate is delimited by the upper and loweredge surfaces 50, 51 (see also Fig. 13), and two opposite, flat end surfaces 52, 53.
An axially running channel 54 is formed in the rear side 49 of the support plate 11, in whichthe ridge 40 of the adjusting plate 12 can engage to form a guide between the two plates. As the bestAs can be seen from Fig. 11, a number (in example five) is axially spaced apart in the bottom of the gutter 54.seats in the form of shallow pits 55 with a spherical shape. The pin 43 can be brought into engagement with anygroup 55.
The front side 48 of the carrier plate 11 has a groove 56 for receiving itsticking blade 7. This groove 56 is delimited by a flat bottom surface 57 and two edge surfaces 58, 59, whichrun parallel to each other and of which the lower 58 is inclined at an acute anglerelative to the bottom surface 57 (see Fig. 13). As best seen in Fig. 9, a threaded hole 60 opens into itthe bottom surface of the groove 57. More specifically, the hole includes a female thread 61, which is recessed inthe hole to be removed from the plane of the bottom surface via an unthreaded, cylindrical surface 62 with a larger oneinner diameter than the thread 61.
The support plate 11 also includes three pairs of through holes 6la / 6lb, 62a / 62b and63a / 63b, for a pair of fixing screws 64, each with its own head 65, which have a cylindrical shape. In eachone of said holes is an annular shoulder surface (indicated at 66), against which the screw headcan be tightened in a recessed condition.
Now refer to Pig. 10, which illustrates the design of the knitting blade 7. OnTraditionally, this leaflet has an elongated, rectangular base shape, and comprises twoplane-parallel side surfaces 67, two opposite and mutually parallel longitudinal edges 68, and twoopposite ends 69 in the form of flat surfaces. In the area of a corner between a single longitudinal edge 68and an end surface 69, a seat 70 is formed, in which a replaceable insert 71 (usually of cemented carbide)can be applied. In the example shown, the knitting blade is designed with two diagonally opposite seats70 for receiving two inserts, one of which can operatively replace the other throughturning of the knitting blade. The two longitudinal edges 68 are cross-sectionally V-shaped in thatinclude two tru ankle surfaces located at an obtuse angle to each other, one of which canbe applied to the edge surface 58 (see Fig. 13).
In the knitting blade 7, the recess is a hole denoted in its entirety by 72, which extendscontinuous between the two side surfaces 67. This hole 72 has a keyhole-like shapecontour shape by including a circular, middle section 73 and two elongated sections215220225230235240121108 14o47sE 874a, 74b. Each such section 74a, 74b is bounded by two straight and mutually parallelhollow edge surfaces 75, which converge in a common, semi-cylindrical end surface 76. The twothe end surfaces 76 are equidistantly separated from the adjacent seat 70 (or the end surface 69 in connectionto this).
In order to fix the knitting blade 7 in the groove 56, no more is used in the example shownor less than a screw 77, which, like other screws, includes a cylindrical skull78. This screw can be passed through a sleeve designated 79, which is applied in the hole 60cylinder surface 62 in the immediate vicinity of the bottom surface 57. In assembled condition, the sleeve 79 forms onestop means which prevent axial displacement of the cutting blade in a direction relative to the support platell, namely in the rearward direction of the tool holder.
The screw head 78 has a diameter which is slightly smaller than the center of the hole 72.circular section 73. On the other hand, its diameter is slightly larger than that of the straight section 74width (which in turn is larger than the diameter of the screw thread).
It should be obvious that the knitting blade 7 can pass through the skull 78 of the screwto be passed past this via the middle section 73. When the blade is to be mounted or disassembled canthe screw 77 is temporarily screwed into the hole 60 with the head 78 spaced a distance from thebottom surface of the groove 57. When the insert blade is passed past the screw head and applied to the bottom surface of the groove57, the same is displaced axially (to the left in Fig. 9/10) until the end surface 76 of the straight sectionhits the sleeve 79. When this happens, the screw can be tightened definitively, whereby the exact position of the knitting bladerelative to the support plate 11 is determined by the sleeve 79 and the screw 77 in combination with each other.
When a used insert is to be replaced by an unused one, this can be done by turningof the knitting blade 7. This turning operation can be carried out quickly and efficiently bythe simple steps of unscrewing the solitary screw 77 one piece, displace the blade so thatthe screw head 78 is located in the center of the center section 73 of the hole, turning the blade so that itthe unused insert is located in the same position as the used one, after which fixing takes placepreviously described manner. In practice, these measures can be implemented with minimal efforttime wasted. Regardless of how the knitting blade is turned, the insert will be located in one and the sameexact position in relation to the support plate 11, more specifically due to the two end surfaces76 in the hole 72 are located at equal distances from the seats 70 and their inserts 71.
By means of the hole pairs 6la / 6lb, 62a / 62b, 63a / 63b the support plate ll can be fixed in threedifferent axial adjustment positions relative to the adjusting body 12. In addition, the possibilities of245250255260265270275121108 14o47sE 9vary the adjustment possibilities due to the fact that the adjusting body 12 comprises two axially separated onespair of threaded holes 45. By, on the one hand, selecting one of the three through holes inthe support plate ll, and, on the other hand, one or the other of the two pairs of threaded holes inthe adjusting body 12, the support body can be given six different setting positions relative to the adjusting body 12.
The reason why the radial adjustment of the support plate - and thus the cutting blade - is relativethe adjusting plate needs to be changed, it may be that different pipes and / or different cutting blades need differentlong protrusions in relation to the tool holder.
Fig. 8 shows how the sensor 39 consists of a rod, which at its rearend includes a pin applicable in the seat 38. At a front end, the sensor is also includeda pulley which can roll against the mantle surface of the pipe 2 to be machined.
For the sake of order, it should be noted that the spatial descriptive attributes, such asused in this text, e.g. "Upper" and "lower", "front" and "rear", etc., refer to thosethe location of the various components in the drawings, and not to what is mounted in the machinethe condition.
Function and advantages of the inventionTo prepare the machine shown in Fig. 1 for operational operation, two are takenbasic measures, namely to ensure that all cuts 71 to the four tools 4located at exactly the same radial distance from the tube 2 placed in the center C of the machine,and that the protrusion of the knitting blades 7 from the tool holder 9 is optimal with respect to boththe diameter of the tube and the road thickness as the nature of the selected cutting blade. The formerthe operation is carried out in a state where the support plate 11 is removed from the adjusting plate 12, andthe sensor 39 (see Fig. 3) is applied in the seat 38 seat. Then the mounting plate 12 fixing screws34, after adjusting the tool and its pulley in the direction of the tube 2, unscrew a piecefrom the base plate 10, the adjusting plate becomes movable so that the spring means 46 can displace the same sofar that the sensor - via the pulley - makes contact with the mantle surface of the pipe. In this state is fixedthe adjusting plate 12 relative to the base plate 10 by tightening the four fixing screws 34.
Such positioning of the adjusting plate 12 is repeated for each of the fourcutting tool 4, included in the machine 1.
In the next step, the individual support plate 11 is connected to the preset adjusting platel2. This is done as follows: On the underside of the support plate 11 (see Fig.17) there is a scale, whichmarks the protrusion length of the knitting blade 7 in relation to the base plate 10. The scale includes six280285290295300305121108 14o47sE 10measurements, between which there are five spaces. The operator can, by selectingdesired protrusion length by means of the scale, manually displacing the support plate 11 to a position in which theyboth screws 64 must be tightened. The selected position corresponds to the position of the pin 43 inrelative to either of the five pits 55 in the bottom of the groove 54. On the tactile road, the operator candistinctly determine this position and tighten the pairs of screws 64 in the pair of cooperating holes 45 inthe adjusting plate 12.
After the support plates ll in all four tools 4 have been tightened, they come offthe support plates buma the cutting blades 7 to assume one and the same radial position in relation tothe center of the machine C. In other words, all four operative inserts 7l are equidistantly separatedfrom said center C. The desired result of this fact is that all four insertswill wear substantially uniformly, and that all spent inserts can be replacedat the same time.
Cutting replacement can be performed either by replacing the individual insert in itexisting knitting blade, or by turning the knitting blade. Turning can be done by screwing77 is unscrewed one piece to enable displacement of the knitting blade, more specifically to oneposition, in which the screw head 78 can be passed through the circular hole section 73. Afterturning the knitting blade and turning it 180 °, the same is reassembled by passingpast the screw head 78 and is displaced so that the end surface 76 of the hole abuts it asstop means serving the sleeve 79. Finally, the skull 78 of the screw 77 is tightened again against the knitting blade,whereby the front indexed, unused insert is fixed in the radial machine position, which is determinedof the axial position of the adjusting body 12 relative to the base plate 10.
An advantage of the invention is that a uniform and precise radial setting ofthe various knitting blades can be carried out without the need for any time-consuming, manual measurementand fine-tuning of the same. The uniformity and accuracy of the positions are thus achieved quickly andsmoothly by means of the spring-loaded arrangement arranged between the base plate and the support platethe adjusting plate via the applied sensor. Another advantage - then the turntable, and thusthe spatial position of the support plate in the machine is well determined - is to change and / or turnthe knitting blades can be executed mainly by the simple grip of loosening a single screwand re-tighten the same. The advantageous result of this is that the set-up times for the machine inin relation to the operating hours, is reduced to a minimum.
Although the knitting blade included in the cutting tool, usually made of steela longer service life than the commonly used carbide inserts, which wear out in a short time310315320325121108 14o47sE 1 1as a result of their immediate contact with the workpiece, they have, after all, a limited oneservice life in relation to the tool holder. For this reason, the knitting blade is a componentor product, which can be marketed separately, ie. without direct connection with itcomposite tool in its entirety. Of this shell, the knitting blade is the subject of suchspecial claims, namely claims 8-10.
Possible modifications of the inventionThe invention is not limited only to what is described above and in the drawingsshowed the design of the composite cutting tool resp. stickbladet. Thus, it is conceivableto equip the cutting blade with only one insert, whereby the keyhole-like hole is not neededinclude more than one straight section, in addition to the circular one. Although it as a stop forthe displacement of the blade in one direction serving the sleeve constitutes a simple and inexpensive solution ofthe problem of determining the position of the cutting blade in the groove of the support body, other solutions are also possible.
Thus, the cutting blade could be inserted axially into the groove from one end thereof, each with astopping shoulder is designed at the opposite end. In such cases, it would for the screwnecessary, through the hole in the knitting blade need not have a keyhole-like contour shape.
Nor does the releasably mountable sensor need to have the shape of a rodwith a rotatable tris said. For example, a pin with a pin could be used for this purposetapered, anterior tip. Also the spring device for the automatic displacement ofthe actuator can be designed in another way than in the form of a lamella affected by several coil springsthe type described. In this case, the adjusting body must be guided axially by two cooperating meansserration surfaces, the serration surface of the base body could be designed directly in the bottom of the hollow insteadfor on a separate base plate of the type exemplified in the drawings.
