Abstract

A forming jaw of a rotary swaging tool for shaping a plastically deformable, preferably metallic, workpiece has a jaw main body and a forming body which is a separate component from the jaw main body and is mounted on the jaw main body, preferably connected to the jaw main body. On a side facing the workpiece, the forming body is bounded by a shaping surface designed for shaping a workpiece. A rotary swaging tool has at least one forming jaw of the above-mentioned type.

Description

[0001] The invention relates to a shaping jaw of a rotary swaging tool for shaping a plastically deformable, preferably metal, workpiece,

[0002] having a main jaw body and

[0003] having a shaping surface which delimits the shaping jaw on a workpiece side of the shaping jaw and is designed for shaping a workpiece.

[0004] The invention also relates to a rotary swaging tool having shaping jaws of the aforementioned type.

[0005] According to DIN 8583, rotary swaging is a method of forming under compressive conditions, in particular free shaping. A rotary swaging tool has shaping jaws which are arranged on opposite sides of a workpiece to be shaped and which are moved in the radial direction of the workpiece axis in order to shape the workpiece by movements directed toward one another. The shaping jaws act on the workpiece by means of shaping surfaces, the geometry of which matches the workpiece geometry to be produced and at which the required shaping forces are introduced into the workpiece. During their movements in the radial direction of the workpiece axis, the shaping jaws are guided in slot-shaped recesses in a shaft of a swaging device provided with the rotary swaging tool. On the side of the shaping jaws remote from the workpiece, there are compensating plates or wedges that are movable relative to the shaping jaws, by means of which the shaping jaws can be positioned in the radial direction of the workpiece axis.

[0006] The generic prior art is disclosed in DE 20 2009 003 703U1 . This document relates to a rotary swaging tool having shaping jaws which have a main body and a shaping surface designed so as to be integral with, and made of the same material as, the main body and intended for acting on a workpiece to be shaped.

[0007] Due to the integral and same-material design, the previously known shaping jaws as a whole have high-quality material properties, which are required in particular for reliably introducing the shaping forces to be applied into the workpiece to be machined. In corresponding applications, the previously known shaping jaws are made of carbide. Due to their consistently high-quality material properties, the previously known shaping jaws are relatively expensive. In addition, the material properties of the shaping jaws are primarily matched to their shaping function. For example, a corresponding hardness of the previously known shaping jaws is, however, disadvantageous in that it causes relatively high wear in the case of relative movements between the shaping jaws and components that are in contact therewith, in particular wedges for the radial adjustment of the shaping jaws.

[0008] The object of the present invention is to avoid the above disadvantages.

[0009] According to the invention, this object is achieved by the shaping jaw according to claim 1 and by the rotary swaging tool according to claim 15.

[0010] In the case of the invention, the shaping surface of the shaping jaw is provided on a shaping body which is structurally separate from the main jaw body of the shaping jaw. As a result of the structural separation, the main jaw body and the shaping body of the shaping jaw can be independently designed. In particular, there is the possibility of manufacturing the main jaw body and the shaping body from different materials. Carbide is preferred as the material for the shaping body, while a less abrasive and / or a lower grade and consequently more cost-effective material such as hardened steel or SPM powder metallurgy steel is considered for the main jaw body.

[0011] Particular embodiments of the shaping jaw according to claim 1 and of the rotary shaping tool according to claim 15 can be found in dependent claims 2 to 14.

[0012] In the embodiment of the invention according to claim 2, the shaping body is fitted into a receptacle of the main jaw body provided for this purpose and is thereby positioned relative to the main jaw body in a defined way and preferably without play.

[0013] Fitting the shaping body into the main jaw body can provide play-free mounting of the shaping body on the main jaw body on all sides or only in individual directions.

[0014] In a further advantageous embodiment of the invention, at least one securing element which, on one side, abuts the outside of the shaping body and, on the other side, is connected to the main jaw body serves to fix the shaping body to the main jaw body (claim 3). As a result of being mounted on the outside of the shaping body, no complicated machining of the shaping body is required for fixing said shaping body. In particular, no fastening bores have to be made in the shaping body, the production of which would be complicated due to the hardness of the shaping body material.

[0015] Claim 4 relates to a preferred arrangement according to the invention of the securing element used to fix the shaping body to the main jaw body. On account of the arrangement in a gap between a wall of the receptacle of the main jaw body on one side and the shaping body on the other side, the securing element does not form an interference contour on the workpiece side of the shaping jaw which could hinder workpiece machining. In addition to the securing element, correspondingly fitting the shaping body into the main jaw body can ensure play-free mounting of the shaping body on the main jaw body. It is conceivable, for example, that the securing element or elements provide for the shaping body to be mounted without play in the longitudinal direction thereof and perpendicularly to the base of the receptacle, and that fitting the shaping body into the main jaw body is provided so as to mount the shaping body without play in the transverse direction thereof in parallel with the base of the receptacle.

[0016] In principle, the shaping body of the shaping jaw according to the invention can be fixedly connected to the main jaw body. According to the invention, a detachable connection between the shaping body and the main jaw body is preferred (claim 5). Due to this feature of the invention, it is possible, for example, to replace a worn shaping body with a new shaping body with little effort. In addition, shaping bodies having different shaping surface geometries can be applied in a simple manner to the same main jaw body in the case of changing machining tasks.

[0017] In the embodiment of the invention according to claim 6, a fastening screw which passes through the securing element and is screwed into the base of the receptacle of the main jaw body provided for the shaping body is used for detachably connecting the shaping body to the main jaw body. By means of the fastening screw, the securing element is fixed in a position in which the securing element is laterally opposite the shaping body. As a result of a wedge-like configuration of the securing element and / or the shaping body on the surfaces facing one another, the securing element on the one hand causing, on the side of the shaping body remote from the securing element, the shaping body to abut, in particular to be supported on, the wall of the receptacle of the main jaw body and thus causes the shaping body to be mounted on the wall of the receptacle of the main jaw body without play perpendicularly to the thread axis of the fastening screw. On the other hand, in cooperation with the securing element, the fastening screw prevents the shaping body from lifting off the base of the receptacle of the main jaw body.

[0018] To fix the shaping body, the securing element is moved relative to the shaping body along the thread axis with a positioning movement in the direction of the base of the receptacle of the main jaw body by screwing the fastening screw into the threaded opening of the main jaw body. Due to the positioning movement of the securing element and the wedge-shaped design of the shaping body and / or of the securing element, the shaping body is thereby applied to the wall of the receptacle of the main jaw body without play, preferably pretensioned against the wall of the receptacle of the main jaw body, by means of the securing element on the side remote from the securing element.

[0019] In a further advantageous embodiment of the invention according to claim 7, it is provided that, on the side of the shaping body that is remote from the securing element, the shaping body engages behind an edge of an opening of the receptacle of the main jaw body in parallel with the base of the receptacle. Due to this feature of the invention, the shaping body that is mounted on the main jaw body is also secured in a formfitting manner against lifting off the base of the receptacle of the main jaw body on the side of the shaping body remote from the securing element. In a preferred development of the invention, the end of the shaping body engaging behind the edge of the opening of the receptacle of the main jaw body has a boundary surface which is inclined toward the base of the receptacle and is opposite an oblique surface of the main jaw body that is inclined in the same direction. The shaping body can be pretensioned against the main jaw body at the opposing oblique surfaces.

[0020] The shaping jaw according to claim 8 of the invention can be flexibly configures for different applications. The possibility according to the invention of reorienting the shaping body relative to the main jaw body can be used, for example, to optimize the transmission of the forces which act in an application-related manner on the shaping surface of the shaping body during workpiece machining and which are to be transferred from the shaping jaw into the main jaw body. Preferably, in its second orientation the shaping body is rotated 180° relative to its first orientation about an axis which is perpendicular to the base of the receptacle provided on the main jaw body for the shaping body.

[0021] According to the invention, there are several ways to fix the shaping body so as to have two different orientations relative to the main jaw body.

[0022] In the case of the embodiment according to claim 9 of the invention, the shaping body is attached to the main jaw body with the first orientation described in relation to claim 6. To reorient the shaping body, this connection between the shaping body and the main jaw body is released and the shaping body is rotated preferably 180° relative to the first orientation. On the side of the receptacle of the main jaw body on which, in the first orientation of the shaping body, the securing element for the first orientation was arranged, the shaping body is now applied to the wall of the receptacle of the main jaw body. On the opposite side of the receptacle of the main jaw body, the securing element is arranged in a gap between the shaping body, which is rotated by 180°, and the wall of the receptacle for the second orientation and is screwed to the main jaw body by means of the fastening screw for the second orientation. For this purpose, the fastening screw for the second orientation is screwed into a threaded opening for the second orientation that opens into the base of the receptacle of the main jaw body. The threaded opening for the second orientation of the shaping body is spaced apart from the threaded opening for the first orientation of the shaping body in the longitudinal direction of the shaping body.

[0023] The shaping body is preferably fastened to the main jaw body with the second orientation relative to the main jaw body with the aid of the same securing element and / or with the aid of the same fastening screw as with the first orientation (claim 10).

[0024] Deviating from the embodiment according to claim 9 of the invention, in the case of the embodiment according to claim 11 of the invention for fixing the shaping body with the second orientation, the same threaded opening is used on the base of the main jaw body as for fixing the shaping body with the first orientation. In both installation positions on the main jaw body, the shaping body is fixed as described with respect to claim 6. Depending on the orientation of the shaping body, the securing element interacts with the first or with the second shaping body-side surface.

[0025] In a further embodiment of the invention, two securing elements are used to connect the shaping body to the main jaw body, which securing elements are each arranged at the two longitudinal ends of the shaping body in a gap between the shaping body and the wall of the receptacle of the main jaw body (claim 12). At each of the two fastening points, the shaping body is detachably connected to the main jaw body in the manner described with respect to claim 6.

[0026] Assembly of the shaping body with two different orientations relative to the main jaw body within the meaning of claim 8 is made possible in a preferred embodiment of the shaping jaw according to claim 12 by both the shaping body-side surface and the further shaping body-side surface are designed to interact with the first securing element and the further securing element (claim 13).

[0027] To simplify disassembly of the shaping body, the main jaw body of the embodiment according to claim 14 of the invention is provided with a passage opening which opens into the base of the receptacle of the main jaw body underneath the shaping body. If necessary, a corresponding pin-like tool can act on the underside of the shaping body through the passage opening and said shaping body can thereby be lifted out of the receptacle of the main jaw body.

[0028] In a preferred embodiment of the invention, the passage opening on the main jaw body is provided with a thread. As a result of the resulting threaded opening, a screw can be rotated in order to release the shaping jaw and a large releasing force can thus be exerted on the underside of the shaping jaw.

[0029] In the following, the invention is explained in more detail on the basis of schematic illustrations given by way of example. In the drawings:

[0030] FIG. 1 shows a swaging device of a rotary swaging machine for shaping plastically deformable metal workpieces using a rotary swaging tool,

[0031] FIG. 2 is a sectional view of the swaging device according to FIG. 1 with the sectional plane II-II in FIG. 1,

[0032] FIG. 3 is a perspective view of a first type of shaping jaw of the rotary swaging tool according to FIGS. 1 and 2,

[0033] FIG. 4 is a sectional view of the shaping jaw according to FIG. 3 with a sectional plane IV indicated in FIG. 3,

[0034] FIGS. 5a, 5b are sectional views of a second type of shaping jaw of the rotary swaging tool according to FIGS. 1 and 2 with a first and a second orientation of a shaping body of the shaping jaw with respect to a main jaw body of the shaping jaw, and

[0035] FIG. 6 is a sectional view of a third type of shaping jaw of the rotary swaging tool according to FIGS. 1 and 2.

[0036] According to FIGS. 1 and 2, a swaging device 1 of a rotary swaging machine for shaping plastically deformable metal tubes has a rotary swaging tool 2 having a total of four shaping jaws 3. A tube to be shaped is indicated in FIGS. 1 and 2 by means of a tube axis 4.

[0037] The shaping jaws 3 lie opposite one another in pairs. To shape a tube, the shaping jaws 3 of each of the shaping jaw pairs are moved towards one another in the radial direction of the tube axis 4.

[0038] During their movements in the radial direction of the tube axis 4, the shaping jaws 3 are guided in guide slots 5 of a jaw guide which is provided at one end of a shaft 6 of the swaging device 1.

[0039] As usual, the shaping movement of the shaping jaws 3 in the direction of a workpiece to be shaped is generated by a relative movement carried out around the tube axis 4 between the shaft 6 and a roller cage 7 surrounding the shaft 6. The roller cage 7 is enclosed by a wear ring 8.

[0040] The shaping jaws 3 are driven in the direction of the tube axis 4 via rams 9, which are likewise movably guided in the radial direction of the tube axis 4 in the guide slots 5 of the shaft 6. On the side remote from the shaping jaws 3, the rams 9 are provided with a ram head 10 which extends in a curved manner on the side facing away from the shaping jaws 3.

[0041] As a result of the relative rotational movement between the shaft 6 and the roller cage 7 of the swaging device 1, the ram head 10 of the rams 9 alternately comes to lie with its highest point directly under a roller 11 of the roller cage 7 and between two rollers 11 of the roller cage 7. When the ram heads 10 of the rams 9 are arranged with their highest point directly below a roller 11, the rotary swaging tool 2 is closed. If the ram heads 10 of the rams 9 are located between two rollers 11, the rotary swaging tool 2 is open.

[0042] The movements of the shaping jaws 3 from the open state to the closed state take place against the action of a restoring force, as a result of which the shaping jaws 3 automatically move from the closed state back into the open state.

[0043] Wedges 12 arranged between each of the shaping jaws 3 and the associated ram 9 are used to adjust the stroke position of the shaping jaws 3 when the rotary swaging tool 2 is closed. To change the end position of the shaping jaws 3 in the radial direction of the tube axis 4, the wedges 12 are positioned relative to the shaping jaws 3 and the rams 9 perpendicularly to the drawing plane of FIG. 1.

[0044] One of the four structurally identical shaping jaws 3 of the rotary swaging tool 2 according to FIGS. 1 and 2 is shown in detail in FIG. 3. The shaping jaw 3 has a main jaw body 13 and a shaping body 14 which is a separate component from the main jaw body 13. In the example shown, the main jaw body 13 is made of SPM steel, and the shaping body 14 is made of carbide.

[0045] The shaping body 14 is provided on a workpiece side with a shaping surface 15 designed to shape a tube.

[0046] The shaping jaw 3 shown here is designed for feed rotary swaging. The shaping body 14 has an inlet side 16 and an outlet side 17 following the inlet side 16 in the longitudinal direction of the shaping body 14. The shaping surface 15 is designed as an inlet cone 18 on the inlet side 16. A calibration portion 19 of the shaping surface 15 follows the inlet cone 18 in the longitudinal direction of the shaping body 14.

[0047] The shaping body 14 is detachably connected to the main jaw body 13 by means of a fastening screw 20. Details of the detachable connection between the main jaw body 13 and the shaping body 14 can be found in FIG. 4.

[0048] As shown in FIG. 4, the shaping body 14 is fitted into a receptacle 21 of the main jaw body 13 provided for this purpose. A wall 22 of the receptacle 21 is immediately adjacent to the shaping body 14 in FIG. 4 on two longitudinal sides and on the transverse side of the shaping body 14 that is on the right in FIG. 4. With its longitudinal sides, the shaping body 14 is readily supported without any play on the wall 22 of the receptacle 21. Play-free mounting of the shaping body 14 on its right transverse side in FIG. 4 and on its left transverse side in FIG. 4 is brought about by means of a securing element 23 which is arranged at the left longitudinal end of the shaping body 14 in a gap between the wall 22 of the receptacle 21 of the main jaw body 13 on one side and the shaping body 14 on the other side.

[0049] The fastening screw 20 passes through the securing element 23 along a thread axis 25 of the fastening screw 20 extending in the transverse direction of a base 24 of the receptacle 21. On the side of the securing element 23 remote from the base 24 of the receptacle 21, the fastening screw 20 engages over the securing element 23 by a screw head 26 perpendicularly to the thread axis 25. With its opposite end, the fastening screw 20 is screwed into a threaded opening or threaded bore 27 of the main jaw body 13 that opens into the base 24 of the receptacle 21 of the main jaw body 13 and is coaxial with the fastening screw 20.

[0050] The securing element 23 and the shaping body 14 lie opposite one another by means of a securing element-side surface 28 and a shaping body-side surface 29. In the region where they make contact, the securing element 23 and the shaping body 14 are wedge-shaped. Accordingly, the securing element-side surface 28 and the shaping body-side surface 29 are inclined toward the thread axis 25 along the thread axis 25, wherein both the securing element-side surface 28 and the shaping body-side surface 29 approach the thread axis 25 toward the base 24 of the receptacle 21 of the main jaw body 13.

[0051] Due to the wedge-like geometry of the securing element 23 and of the shaping body 14 in the region where they make contact, the shaping body 14 is pre-tensioned against the wall 22 of the receptacle 21 of the main jaw body 13 by means of the securing element 23 on the side remote from the securing element 23 and is thereby mounted on the main jaw body 13 without play in the longitudinal direction of the shaping body 14. In the opposite direction, the shaping body 14 is supported without play on the wall 22 of the receptacle 21 via the securing element 23. At the same time, the shaping body 14 is pressed against the base 24 of the receptacle 21 of the main jaw body 13 by the securing element 23.

[0052] As can also be seen in FIG. 4, the main jaw body 13 has, at a distance from the threaded bore 27, a passage opening 30 which opens up underneath the shaping body 14 into the base 24 of the receptacle 21 of the main jaw body 13. The passage opening 30 is used during the disassembly of the shaping body 14. After the fastening screw 20 has been loosened and the securing element 23 has been removed, a pin-like tool is applied to the underside of the shaping body 14 through the passage opening 30. Due to the action of the pin-like tool, the shaping body 14 is lifted out of the receptacle 21 of the main jaw body 13.

[0053] If the shaping body 14 and the wall 22 of the receptacle 21 of the main jaw body 13 extend on the side of the shaping body 14 on the right in FIG. 4, as shown by dashed lines, on the side of the shaping body remote from the securing element 23, the shaping body 14 engages by means of a second shaping body-side surface 29a behind an edge of an opening of the receptacle 21 that is opposite the base 24 of the receptacle 21 of the main jaw body 13 in parallel with the base 24 of the receptacle 21. In this way, the shaping body 14 mounted on the main jaw body 13 is also secured in a form-fitting manner against lifting off the base 24 of the receptacle 21 of the main jaw body 13 on the side of the shaping body remote from the securing element 23.

[0054] In addition, the shaping body 14 provided with the second shaping body-side surface 29a can be detachably connected to the main jaw body 13 also with a second orientation relative to the main jaw body 13. With the second orientation, the shaping body 14 is rotated 180° relative to the first orientation shown. The inlet side 16 and the outlet side 17 of the shaping body 14 are switched in the different orientations of the shaping body 14. With both orientations relative to the main jaw body 13, the shaping body 14 can be detachably fixed to the main jaw body 13 by means of the fastening screw 20 and the securing element 23.

[0055] FIGS. 5a and 5b show a shaping body 14 of a shaping jaw 3a with a first orientation (FIG. 5a) and with a second orientation (FIG. 5b) with respect to a main jaw body 13. Reorientation of the shaping body 14 with respect to the main jaw body 13 is carried out, for example, in order to optimize the transmission of the forces at the shaping jaw 3a, which act in an application-related manner at a shaping surface 15 of the shaping body 14 during workpiece machining and which are to be transferred from the shaping jaw 14 into the main jaw body 13. The shaping jaw 3a can be installed on the swaging device 1 according to FIGS. 1 and 2 instead of the shaping jaw 3 shown in FIGS. 3 and 4.

[0056] The same reference signs are used in FIGS. 3 and 4 on the one hand and in FIGS. 5a and 5b on the other hand for corresponding details.

[0057] In the case of the first orientation of the shaping body 14 shown in FIG. 5a, the detachable connection of the shaping body 14 to the main jaw body 13 is produced in the same way as the detachable connection of the shaping body 14 to the main jaw body 13 in FIGS. 3 and 4.

[0058] If necessary, the connection produced in FIG. 5a between the shaping body 14 and the main jaw body 13 is released and the shaping body 14 is rotated by 180° relative to the orientation according to FIG. 5a and thereby oriented relative to the main jaw body 13 as shown in FIG. 5b.

[0059] On the side of the receptacle 21 on which the securing element 23 was arranged in the first orientation of the shaping body 14, the shaping body 14 is now applied to the wall 22 of the receptacle 21 of the main jaw body 13. On the opposite side of the receptacle 21, the securing element for the second orientation, in the present case the securing element 23 also already provided in FIG. 5a, is arranged in a gap between the shaping body 14, which is rotated by 180°, and the wall 22 of the receptacle 21 of the main jaw body 13 and is screwed to the main jaw body 13 by means of the fastening screw 20 that is also used as a fastening screw for the second orientation. For this purpose, the fastening screw 20 is screwed into a threaded opening 27a for the second orientation that opens up into the base 24 of the receptacle 21 of the main jaw body 13. The threaded opening 27a for the second orientation of the shaping body 14 is spaced apart from the threaded opening 27 for the first orientation of the shaping body 14 in the longitudinal direction thereof.

[0060] Also under the installation conditions according to FIG. 5b, the securing element 23 is supported by means of the securing element-side surface 28 on the shaped-body side surface 29 of the shaping body 14. By means of the securing element 23, the shaping body 14 is pretensioned against the wall 22 of the receptacle 21 of the main jaw body 13 on the side of the shaping body 14 that is on the left in FIG. 5b.

[0061] In the first orientation of the shaping body 14 according to FIG. 5a, the threaded opening 27a can be used during the disassembly of the shaping body 14 and correspondingly form a passage opening 30a of the main jaw body 13 that opens up below the shaping body 14. In the second orientation of the shaping body 14 according to FIG. 5b, the threaded opening 27 is considered as a correspondingly usable passage opening 30b of the main jaw body 13.

[0062] Deviating from the passage opening 30 according to FIG. 4, the passage openings 30a, 30b are provided with a thread on the opening wall. To loosen the shaping body 14, a screw can therefore be rotated from the outside through the passage openings 30a, 30b until the leading end of the screw acts on the underside of the shaping body 14 to be disassembled. By continuing to screw the screw into the passage openings 30a, 30b, a large loosening force can be exerted on the underside of the shaping body 14.

[0063] FIG. 6 shows a shaping jaw 3b which is also designed for installation on the swaging device 1 shown in FIGS. 1 and 2.

[0064] A shaping body 14 of the shaping jaw 3b is detachably connected to a main jaw body 13 of the shaping jaw 3b on its side that is on the left in FIG. 6 in the same way as the shaping jaw 14 is to the main jaw body 13 in FIGS. 3 and 4.

[0065] In addition to the securing element 23 on the side of the shaping body 14 that is on the left in FIG. 6, a further securing element 43 is provided on the side of the shaping body 14 that is on the right in FIG. 6, by means of which further securing element the shaping body 14 is supported on the wall 22 and on the base 24 of the receptacle 21 of the main jaw body 13.

[0066] The further securing element 43 is arranged on the side of the shaping body 14 remote from the securing element 23 in a gap between the wall 22 of the receptacle 21 of the main jaw body 13 on one side and the shaping body 14 on the other side and is mounted, on one side, on the wall 22 of the receptacle 21 of the main jaw body 13 and on the shaping body 14 on the other side.

[0067] A further fastening screw 40 is provided for detachably connecting the shaping body 14 to the main jaw body 13 in addition to the fastening screw 20.

[0068] The further fastening screw 40 passes through the further securing element 43 along a further thread axis 45 of the further fastening screw 40 which extends in the transverse direction of the base 24 of the receptacle 21 of the main jaw body 13. On the side remote from the base 24 of the receptacle 21, the further fastening screw 40 extends over the further securing element 43 by means of a further screw head 46 in the transverse direction of the further thread axis 45. At the base 24 of the receptacle 21, the further fastening screw 40 is screwed along the further thread axis 45 into a further threaded opening 47 of the main jaw body 13 that opens into the base 24 of the receptacle 21 and is coaxial with the further fastening screw 40.

[0069] The further securing element 43 is supported by means of a further securing element-side surface 48 on a further shaping body-side surface 49 of the shaping body 14. The further securing element-side surface 48 and the further shaping body-side surface 49 extend along the further thread axis 45 and lie opposite one another perpendicularly to the further thread axis 45. Both the further securing element-side surface 48 and the further shaping body-side surface 49 are designed in the manner of a wedge surface and are inclined toward the further thread axis 45. Both wedge surfaces approach the further thread axis 45 toward the base 24 of the receptacle 21.

[0070] The shaping body 14 of the shaping jaw 3b can also be attached to the main jaw body 13 with two different orientations relative to the main jaw body 13, wherein, with the second orientation, the shaping body 14 is rotated by 180° relative to the first orientation.

[0071] For this purpose, both the shaping body-side surface 29 and the further shaping body-side surface 49 are designed to interact with the securing element 23 and the further securing element 43.
