Abstract
Description
[Technical Field]
[0001] The present invention relates to a forming jaw of a rotary swaging tool for deforming a plastically deformable, preferably metallic, workpiece, comprising: A jaw base, a forming surface defining a forming jaw on the workpiece side of the forming jaw and configured for deforming the workpiece; The present invention relates to a forming jaw comprising:
[0002] The present invention further relates to a rotary swaging tool having forming jaws of the type described above.
[0003] According to DIN 8583, rotary swaging is a method of pressure deformation, specifically free-forming. Rotary swaging tools have forming jaws arranged on opposite sides of the workpiece to be deformed, which are moved radially from the workpiece axis in opposing directions to deform the workpiece. The forming jaws apply a load to the workpiece with forming surfaces whose geometry is adapted to the workpiece geometry to be produced, and at which the required deformation forces are introduced into the workpiece. During the forming jaws' movement radially from the workpiece axis, they are guided in a slot-shaped recess in one shaft of the swaging mechanism comprising the rotary swaging tool. A compensating plate or wedge movable relative to the forming jaw is located on the side of the forming jaw away from the workpiece, allowing the forming jaw to be advanced radially from the workpiece axis by means of this compensating plate or wedge.
[0004] The prior art mentioned at the outset is disclosed in German Utility Model No. 202009003703. This document relates to a rotary swaging tool with a base body and forming jaws which have forming surfaces which are formed integrally and in a material-coherent manner with the base body and which are intended to apply a load to a workpiece to be deformed.
[0005] Due to their one-piece, material-uniform construction, the previously known forming jaws have high-value material properties overall. These material properties are necessary, in particular, for functionally reliable introduction of the forming forces to be applied into the workpiece to be processed. In corresponding use cases, the previously known forming jaws are manufactured from cemented carbide. Due to their consistently high-value material properties, the previously known forming jaws are relatively expensive. Furthermore, the material properties of the forming jaws are preferentially adapted to their forming function. However, the correspondingly set hardness of the previously known forming jaws is disadvantageous in that it causes relatively strong wear during relative movement of the forming jaws and therefore on the contacting components, in particular the wedges for radially displacing the forming jaws.
[0006] It is an object of the present invention to avoid the above-mentioned drawbacks.
[0007] According to the invention, this problem is solved by a forming jaw according to claim 1 and a rotary swaging tool according to claim 15.
[0008] In the present invention, the forming surfaces of the forming jaws are provided on a forming body that is structurally separated from the jaw base body of the forming jaws. This structural separation allows the jaw base body and the forming body of the forming jaws to be constructed independently of each other. In particular, it is possible to manufacture the jaw base body and the forming body from different materials. While hard alloys are preferred as materials for the forming body, less wear-resistant and / or less valuable, and therefore less expensive materials such as hardened steel or powder metallurgical SPM steel are also considered for the jaw base body.
[0009] Special configurations of the forming jaws according to claim 1 and of the rotary swaging tool according to claim 15 are set forth in the dependent claims 2 to 14.
[0010] In the construction of the invention as claimed in claim 2, the shaped body is inserted into a receiving portion of the jaw base provided for the shaped body and is thereby positioned in relation to the jaw base in a defined and preferably play-free manner.
[0011] The fitting of the molded body into the jaw base can result in a play-free support of the molded body on the jaw base all around or only in a single direction.
[0012] In another preferred embodiment of the present invention, at least one fixing element is used to fix the molded body in the jaw base, which rests on the outer surface of the molded body on the one hand and is connected to the jaw base on the other hand (claim 3). Due to the support on the outer surface of the molded body, extensive machining of the molded body is not necessary to fix the molded body in place. In particular, it is not necessary to machine mounting holes in the molded body. The manufacturing of mounting holes would have to be elaborate due to the hardness of the molded body material.
[0013] Claim 4 relates to a preferred arrangement of the fastening elements, which serve to fix the molded body on the jaw base. Due to their location in the gap between the wall of the jaw base receptacle on the one hand and the molded body on the other hand, the fastening elements do not form any obstructing contours on the workpiece side of the forming jaws that could hinder workpiece machining. In addition to the fastening elements, a corresponding engagement of the molded body into the jaw base can be beneficial for play-free support of the molded body on the jaw base. For example, it is conceivable that one or more fastening elements provide play-free support of the molded body in the longitudinal direction of the molded body and perpendicular to the bottom of the receptacle, and that the engagement of the molded body into the jaw base is defined for play-free support of the molded body in its transverse direction, parallel to the bottom of the receptacle.
[0014] In principle, the forming bodies of the forming jaws according to the invention may be fixedly connected to the jaw base. According to the invention, a detachable connection between the forming bodies and the jaw base is preferred (claim 5). This feature of the invention makes it possible, for example, to replace worn forming bodies with new forming bodies with minimal effort. Furthermore, when changing processing tasks, forming bodies with different geometric shapes of the forming surface can be easily attached to the same jaw base.
[0015] In the construction of claim 6, a mounting screw is used to releasably connect the molded body to the jaw base, passing through the fastening element and screwed into the bottom of the receiving section of the jaw base provided for the molded body. The fastening element secures the fastening element in a position where it laterally faces the molded body. Due to the wedge-shaped configuration of the fastening element and / or the molded body on their facing surfaces, the fastening element, on the one hand, abuts, particularly supports, the molded body on the side of the molded body facing away from the fastening element against the wall of the receiving section of the jaw base, thus supporting the molded body without play in the direction perpendicular to the thread axis of the mounting screw against the wall of the receiving section of the jaw base. On the other hand, the mounting screw, in cooperation with the fastening element, prevents the molded body from lifting out of the bottom of the receiving section of the jaw base.
[0016] To fix the molded body in place, the fixing element is moved relative to the molded body along the thread axis in a feed motion toward the bottom of the receiving part of the jaw base by screwing the mounting screw into the threaded opening of the jaw base. Due to the feed motion of the fixing element and the wedge-shaped configuration of the molded body and / or the fixing element, the molded body abuts without play against the wall of the receiving part of the jaw base on the side facing away from the fixing element by the fixing element, and preferably the molded body is preloaded by the fixing element against the wall of the receiving part of the jaw base.
[0017] In a further advantageous embodiment of the invention, as set forth in claim 7, the molded body engages from behind with the edge of the opening of the receptacle of the jaw base, on its side facing away from the fastening element, parallel to the bottom of the receptacle. This feature of the invention ensures that the molded body, mounted on the jaw base, prevents the jaw base from lifting away from the bottom of the receptacle by a positive lock. In a preferred development of the invention, the end of the molded body engaging from behind with the edge of the opening of the receptacle of the jaw base has a delimiting surface. This delimiting surface extends obliquely relative to the bottom of the receptacle and faces a slope of the jaw base that is inclined in the same direction. The molded body may be preloaded against the jaw base at the opposing slopes.
[0018] The forming jaws according to the invention as defined in claim 8 can be flexibly configured for different use cases. The possibility afforded by the invention for reorienting the forming body relative to the jaw base can be used, for example, in application-related terms at the forming surface of the forming body during workpiece processing to optimize the transfer of forces to be transferred from the forming jaws to the jaw base. More preferably, in the second orientation, the forming body is rotated by 180° relative to the first orientation about an axis that runs perpendicular to the bottom of the receptacle in the jaw base provided for the forming body.
[0019] For the fixing of a molded body with two different orientations relative to the jaw base, several possibilities exist according to the invention.
[0020] In the construction of the present invention as defined in claim 9, a molded body having a first orientation is attached to the jaw base, as defined in claim 6. To change the orientation of the molded body, the connection between the molded body and the jaw base is released, and the molded body is rotated, preferably by 180°, relative to the first orientation. The molded body abuts against the wall of the jaw base housing on the side of the jaw base housing where the fixing element for the first orientation was located when the molded body was in the first orientation. On the opposite side of the jaw base housing, in the gap between the molded body rotated by 180° and the wall of the housing, a fixing element for the second orientation is arranged and screwed to the jaw base using a mounting screw for the second orientation. For this purpose, the mounting screw for the second orientation is screwed into a threaded opening for the second orientation, which opens into the bottom of the jaw base housing. The threaded opening for the second orientation of the molded body is spaced apart in the longitudinal direction of the molded body from the threaded opening for the first orientation of the molded body.
[0021] More preferably, the molded body is attached to the jaw base in the second orientation relative to the jaw base using the same fixing elements and / or using the same mounting screws as in the first orientation (claim 10).
[0022] In contrast to the inventive design according to claim 9, in the inventive design according to claim 11, the same threaded opening in the bottom of the jaw base is used to fix the molded body with the second orientation as is used to fix the molded body with the first orientation. In both mounting positions in the jaw base, the molded body is fixed as described in claim 6. Depending on the orientation of the molded body, the fixing element cooperates with a side surface of the first molded body or with a side surface of the second molded body.
[0023] In another embodiment of the invention, two fixing elements are used to connect the mold to the jaw base, and these fixing elements are arranged at both longitudinal ends of the mold in the gap between the mold and the wall of the receiving part of the jaw base (claim 12). In each of both mounting positions, the mold is detachably connected to the jaw base in the manner described in claim 6.
[0024] The assembly of a molded body having two different orientations relative to the jaw base in accordance with claim 8 is made possible in a preferred configuration of the mold jaw according to claim 12 in that both the molded body side surface and the further molded body side surface are configured to cooperate with the first fixing element and the further fixing element (claim 13).
[0025] To facilitate the removal of the molded body, the jaw base of the construction according to claim 14 is provided with a through-opening, which opens into the bottom of the receptacle of the jaw base below the molded body. If necessary, the molded body can be lifted out of the receptacle of the jaw base by applying a load to its underside through the through-opening with a correspondingly formed pin-shaped tool.
[0026] In a preferred embodiment of the invention, the through openings in the jaw base are provided with threads, which allow a screw to be turned to release the forming jaws, thereby exerting a large amount of release force on the underside of the forming jaws.
[0027] The invention will be explained in more detail below on the basis of exemplary schematic drawings. [Brief explanation of the drawings]
[0028] [Figure 1] 1 shows a swaging mechanism of a rotary swaging machine for deforming a plastically deformable metal workpiece, equipped with a rotary swaging tool; FIG. [Figure 2] 2 is a cross-sectional view showing the swaging mechanism shown in FIG. 1 taken along the cross section II-II shown in FIG. 1. [Figure 3] FIG. 3 is a perspective view showing a forming jaw of a first construction type of the rotary swaging tool shown in FIGS. 1 and 2. [Figure 4] 4 is a cross-sectional view of the forming jaw shown in FIG. 3 taken along section IV shown in FIG. 3. [Figure 5a] 3 is a cross-sectional view showing a forming jaw of a second construction type of the rotary swaging tool shown in FIGS. 1 and 2 in a first orientation of the forming body of the forming jaw relative to the jaw base of the forming jaw. FIG. [Figure 5b] 3 is a cross-sectional view showing a forming jaw of a second construction type of the rotary swaging tool shown in FIGS. 1 and 2 with a second orientation of the forming body of the forming jaw relative to the jaw base of the forming jaw. FIG. [Figure 6] 3 is a cross-sectional view showing a forming jaw of a third construction type of the rotary swaging tool shown in FIGS. 1 and 2. FIG.
[0029] 1 and 2, a swaging mechanism 1 of a rotary swaging machine for deforming plastically deformable metal tubes comprises a rotary swaging tool 2 with a total of four forming jaws 3. The tube to be deformed is indicated in FIGS. 1 and 2 by a tube axis 4.
[0030] The forming jaws 3 are arranged in pairs facing each other and, in order to deform the tube, the respective forming jaws 3 of a forming jaw pair are moved relative to one another in the radial direction of the tube axis 4 .
[0031] During the movement of the forming jaws 3 in the radial direction of the tube axis 4 , the forming jaws 3 are guided in guide slits 5 of a jaw guide provided at one end of a shaft 6 of the swaging mechanism 1 .
[0032] As is customary, the deforming movement of the forming jaws 3 in the direction towards the workpiece to be deformed is generated by the relative movement of the shaft 6 and the roller cage 7 surrounding this shaft 6, carried out about the tube axis 4. The roller cage 7 is surrounded by a wear ring 8.
[0033] The drive of the forming jaws 3 towards the tube axis 4 is effected by a plunger 9 which is likewise guided in the guide slot 5 of the shaft 6 so as to be movable in the radial direction of the tube axis 4. On its side facing away from the forming jaws 3, the plunger 9 is provided with a plunger head 10 which extends in a curved manner on the side facing away from the forming jaws 3.
[0034] Due to the relative rotational movement of the shaft 6 of the swaging mechanism 1 and the roller cage 7, the plunger head 10 of the plunger 9 is alternately positioned with its highest point directly below one roller 11 of the roller cage 7 and between two rollers 11 of the roller cage 7. When the plunger head 10 of the plunger 9 is positioned with its highest point directly below one roller 11, the rotary swaging tool 2 is closed. When the plunger head 10 of the plunger 9 is positioned between the two rollers 11, the rotary swaging tool 2 is open.
[0035] The movement of the forming jaws 3 from the open state to the closed state is carried out against the action of a return force which automatically moves the forming jaws 3 back from the closed state to the open state.
[0036] To adjust the stroke position of the forming jaws 3 when the rotary swaging tool 2 is closed, a wedge 12 is used, which is disposed between each forming jaw 3 and the corresponding plunger 9. This wedge 12 is moved relative to the forming jaw 3 and plunger 9 perpendicular to the drawing plane of FIG. 1 in order to change the end position of the forming jaw 3 in the radial direction of the tube axis 4.
[0037] One of the four identical forming jaws 3 of the rotary swaging tool 2 shown in Figures 1 and 2 is shown in detail in Figure 3. The forming jaw 3 has a jaw base 13 and a forming body 14 structurally separated from the jaw base 13. The jaw base 13 is made of SPM steel in the illustrated example, and the forming body 14 is made of cemented carbide.
[0038] The forming body 14 has on one workpiece side a forming surface 15 formed for deforming the tube.
[0039] The forming jaw 3 shown in Figure 3 is designed for feed rotary swaging. The forming body 14 has an entry side 16 and an exit side 17 that follows the entry side 16 in the longitudinal direction of the forming body 14. On the entry side 16, the forming surface 15 is configured as an entry cone 18. This entry cone 18 is followed in the longitudinal direction of the forming body 14 by a calibrated section 19 of the forming surface 15.
[0040] The forming body 14 is removably connected to the jaw base body 13 by means of mounting screws 20. Details of the removably connected jaw base body 13 and forming body 14 can be seen in FIG.
[0041] According to Fig. 4, the molded body 14 is fitted into a receptacle 21 provided for the molded body 14 in the jaw base 13. A wall 22 of this receptacle 21 adjoins the molded body 14 on both longitudinal sides in Fig. 4 and on the right-hand lateral side of the molded body 14 in Fig. 4. The molded body 14 is supported on its longitudinal sides by the wall 22 of the receptacle 21 without any play. Support of the molded body 14 on the left and right lateral sides in Fig. 4 is achieved by a fixing element 23. The fixing element 23 is arranged at the left-hand longitudinal end of the molded body 14 in the gap between the wall 22 of the receptacle 21 provided in the jaw base 13 on the one hand and the molded body 14 on the other hand.
[0042] The fixing element 23 is penetrated by the mounting screw 20 along a thread axis 25 of the mounting screw 20 that extends transversely to the bottom 24 of the receiving portion 21. On the side of the fixing element 23 away from the bottom 24 of the receiving portion 21, the mounting screw 20 caps the fixing element 23 with a screw head 26 that is perpendicular to the thread axis 25. The end of the mounting screw 20 opposite the screw head 26 is screwed into a threaded opening or threaded bore 27 of the jaw base 13 that opens into the bottom 24 of the receiving portion 21 of the jaw base 13 and is coaxial with the mounting screw 20.
[0043] The fixing element 23 and the shaped body 14 face each other with a fixing element side surface 28 and a shaped body side surface 29. In their contact area, the fixing element 23 and the shaped body 14 are wedge-shaped. Accordingly, the fixing element side surface 28 and the shaped body side surface 29 extend along the thread axis 25 and incline relative to this thread axis 25, with both the fixing element side surface 28 and the shaped body side surface 29 approaching the thread axis 25 towards the bottom 24 of the receiving section 21 of the jaw base 13.
[0044] Due to the wedge-shaped geometry of the fixing element 23 and the forming body 14 in their contact area, the forming body 14 is preloaded by the fixing element 23 on the side remote from the fixing element 23 towards the wall 22 of the receiving section 21 of the jaw base 13, so that the forming body 14 is supported without play on the jaw base 13 in the longitudinal direction of the forming body 14. In the opposite direction, the forming body 14 is supported without play on the wall 22 of the receiving section 21 via the fixing element 23. At the same time, the forming body 14 is pressed by the fixing element 23 against the bottom 24 of the receiving section 21 of the jaw base 13.
[0045] 4, the jaw base 13 has a through-opening 30 spaced from the threaded bore 27 and opening into the bottom 24 of the receiving section 21 of the jaw base 13 below the forming body 14. The through-opening 30 is used to remove the forming body 14. After the mounting screws 20 are loosened and the fixing elements 23 are removed, a load is applied to the underside of the forming body 14 through the through-opening 30 with a pin-shaped tool. As a result of the load applied by the pin-shaped tool, the forming body 14 is lifted out of the receiving section 21 of the jaw base 13.
[0046] 4, when the wall 22 of the molded body 14 and the receiving section 21 of the jaw base 13 extend, the molded body 14 engages with its second molded body side surface 29a, on the side remote from the fastening element 23, from behind on the edge of the opening of the receiving section 21, which is located opposite the bottom 24 of the receiving section 21 of the jaw base 13, parallel to the bottom 24 of the receiving section 21. This prevents the molded body 14, which has been assembled to the jaw base 13, from lifting up from the bottom 24 of the receiving section 21 of the jaw base 13 in a form-locking manner, even on the side remote from the fastening element 23.
[0047] Furthermore, the molded body 14 with the second molded body side surface 29a can be removably coupled to the jaw base 13 in a second orientation relative to the jaw base 13 in addition to the orientation shown in Figure 4. In the second orientation, the molded body 14 is rotated by 180° with respect to the first orientation shown. The entry side 16 and the exit side 17 of the molded body 14 are interchanged in the case of a different orientation of the molded body 14. In both orientations relative to the jaw base 13, the molded body 14 can be removably fixed in position on the jaw base 13 by means of the mounting screw 20 and the fixing element 23.
[0048] 5a and 5b, the forming body 14 of the forming jaw 3a is shown in a first orientation (FIG. 5a) and a second orientation (FIG. 5b) relative to the jaw base 13. The reorientation of the forming body 14 relative to the jaw base 13 is performed, for example, to optimize the transmission of forces in the forming jaw 3a, which act on the forming surface 15 of the forming body 14 in a manner relevant to the application during workpiece processing and can be transferred from the forming jaw 14 to the jaw base 13. The forming jaw 3a can be incorporated into the swaging mechanism 1 according to FIGS. 1 and 2 instead of the forming jaw 3 shown in FIGS. 3 and 4.
[0049] The same reference numerals are used for corresponding details in Figures 3 and 4 on the one hand and Figures 5a, 5b on the other hand.
[0050] The detachable connection between the molded body 14 and the jaw base 13 is formed in the first orientation of the molded body 14 shown in Figure 5a in the same manner as the detachable connection between the molded body 14 and the jaw base 13 shown in Figures 3 and 4.
[0051] If necessary, the bond between the compact 14 and the jaw base 13 formed in Figure 5a is dissolved and the compact 14 is rotated by 180° relative to the orientation of Figure 5a, so that it is oriented relative to the jaw base 13 as shown in Figure 5b.
[0052] On the side of the receiving section 21 where the fixing element 23 was located in the first orientation of the molded body 14, the molded body 14 rests against the wall 22 of the receiving section 21 of the jaw base 13. On the opposite side of the receiving section 21, in the gap between the molded body 14 rotated 180° and the wall 22 of the receiving section 21 of the jaw base 13, a fixing element for the second orientation, in this case the fixing element 23 already shown in FIG. 5a, is arranged. The fixing element is screwed to the jaw base 13 by means of a mounting screw 20 that also serves as a mounting screw for the second orientation. For this purpose, the mounting screw 20 is screwed into a threaded opening 27a for the second orientation, which opens into the bottom 24 of the receiving section 21 of the jaw base 13. The threaded opening 27a for the second orientation of the molded body 14 is spaced apart in the longitudinal direction of the molded body 14 from the threaded opening 27 for the first orientation of the molded body 14.
[0053] In the assembled state shown in Fig. 5b, the fixing element 23 is also supported by its fixing element side 28 on the side 29 of the molded body 14. The fixing element 23 preloads the molded body 14 on the left side of the molded body 14 in Fig. 5b against the wall 22 of the receiving section 21 of the jaw base 13.
[0054] In a first orientation of the molded body 14 shown in Figure 5a, the threaded opening 27a can be used when removing the molded body 14 and can thus form a through opening 30a in the jaw base 13 that opens below the molded body 14. In a second orientation of the molded body 14 shown in Figure 5b, the threaded opening 27a can be considered as a correspondingly usable through opening 30b in the jaw base 13.
[0055] Unlike the through-opening 30 shown in Figure 4, the through-openings 30a, 30b have threads on the opening walls. Therefore, to remove the molding 14, a screw can be rotated from the outside through the through-openings 30a, 30b until the leading end of the screw applies a load to the underside of the molding 14 to be removed. Continued threading of the screw into the through-openings 30a, 30b allows a quantitatively greater release force to be applied to the underside of the molding 14.
[0056] FIG. 6 shows a forming jaw 3b configured for incorporation in the swaging mechanism 1 also shown in FIGS.
[0057] The forming body 14 of the forming jaw 3b is removably connected to the jaw base 13 of the forming jaw 3b on the left side as shown in Figure 6 in a manner similar to the jaw base 13 and forming jaw 14 of Figures 3 and 4.
[0058] In addition to the fixing element 23 provided on the left side of the forming body 14 as shown in FIG. 6, another fixing element 43 is provided on the right side of the forming jaw 14 as shown in FIG. 6, by means of which the forming body 14 is supported on the wall 22 and on the bottom 24 of the receiving portion 21 of the jaw base 13.
[0059] Another fixing element 43 is arranged on the side of the forming body 14 away from the fixing element 23 in the gap between the wall 22 of the receiving portion 21 of the jaw base body 13 on the one hand and the forming body 14 on the other hand, and is supported on the wall 22 of the receiving portion 21 of the jaw base body 13 on the one hand and on the forming body 14 on the other hand.
[0060] In addition to the mounting screws 20, another mounting screw 40 is provided for removably connecting the molded body 14 to the jaw base 13.
[0061] The other mounting screw 40 passes through the other fixing element 43 along a different thread axis 45 of the other mounting screw 40 that extends laterally to the bottom 24 of the receiving section 21 of the jaw base 13. On the side away from the bottom 24 of the receiving section 21, the other mounting screw 40 caps the other fixing element 43 with a different screw head 46 that is laterally aligned with the different thread axis 45. At the bottom 24 of the receiving section 21, the other mounting screw 40 is screwed along the different thread axis 45 into a different threaded opening 47 of the jaw base 13 that opens into the bottom 24 of the receiving section 21 and is coaxial with the other mounting screw 40.
[0062] The further fixing element 43 has a further fixing element lateral surface 48 which rests against a further shaped body lateral surface 49 of the shaped body 14. The further fixing element lateral surface 48 and the further shaped body lateral surface 49 extend along a further thread axis 45 and face perpendicularly to the further thread axis 45. Both the further fixing element lateral surface 48 and the further shaped body lateral surface 49 form a kind of wedge surface which is inclined relative to the further thread axis 45. Both wedge surfaces approach the further thread axis 45 towards the bottom 24 of the receiving part 21.
[0063] The forming body 14 of the forming jaw 3b can also be attached to the jaw base 13 in two different orientations relative to the jaw base 13, the second orientation of the forming body 14 being rotated 180° relative to the first orientation.
[0064] For this purpose, both the profile side 29 and the further profile side 49 are designed to cooperate with the fastening element 23 and the further fastening element 43 .
