Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a twisting mechanism for a stepping mold. Background Technology
[0002] A stepping die, more accurately termed a "progressive die," is defined as a die that has two or more stations in the feeding direction of the strip material and completes two or more stamping operations at different stations in one stroke of the press.
[0003] For example Figure 1 The material strip shown has a workpiece. The existing twisting mechanism includes an upper twisting module and a lower twisting module. The upper and lower twisting modules work together to twist the material strip. Currently, this twisting mechanism only has a support plane on the outside of the lower twisting module. This support plane abuts against the workpiece to support it, but the material strip lacks support. As a result, when the pressure is applied, the connection between the material strip and the workpiece is subjected to a large impact, which can easily lead to the breakage of the connection between the material strip and the workpiece, affecting the production quality. Utility Model Content
[0004] Therefore, it is necessary to provide a twisting mechanism for stepping dies to address the problem that existing twisting mechanisms only have a support plane on the outside of the lower twisting module to support the workpiece, while the strip lacks support. During stamping, the connection between the strip and the workpiece is subjected to a large impact, causing the connection between the strip and the workpiece to break, which affects the production quality.
[0005] A torsion mechanism for a stepper die includes:
[0006] Upper twisting module;
[0007] The lower twisting module is provided with a through groove and a first support plane. The upper twisting module is disposed opposite to the lower twisting module.
[0008] A floating block, which moves vertically through the through slot, and the floating block is provided with a second supporting plane; and
[0009] The lower end of the floating block is fixedly connected to the telescopic end of the telescopic rod;
[0010] When the mold is opened, both the first support plane and the second support plane abut against the strip to support it.
[0011] The aforementioned stepping die twisting mechanism, through the cooperation of the upper twisting module, lower twisting module, floating block, and telescopic rod, can always support the strip before and during the pressing process. It can effectively prevent the strip and workpiece from breaking at the connection point due to excessive impact force during pressing, thus effectively improving the yield rate and production quality.
[0012] In one embodiment, there are two lower twisting modules, which are spaced apart, and the floating block corresponds one-to-one with the lower twisting module.
[0013] In one embodiment, the stepping die twisting mechanism further includes a support block, which is movably disposed between the two lower twisting modules, and the lower end of the support block is fixedly connected to the telescopic end of the telescopic rod.
[0014] In one embodiment, the stepping die twisting mechanism further includes a first guide block, which is fixedly connected to the lower twisting module. The first guide block is provided with a first guide groove, which communicates with the through groove. The first guide block corresponds one-to-one with the floating block.
[0015] In one embodiment, the stepping die twisting mechanism further includes a second guide block, which is disposed between the support block and the lower twisting module. There are two second guide blocks, and a second guide groove adapted to the support block is provided between the two second guide blocks.
[0016] In one embodiment, the lower end of the upper twisting module is provided with a first abutting plane and an upper twisting slope. There are two upper twisting slopes, which are respectively located on both sides of the first abutting plane and tilt downwards towards each other.
[0017] In one embodiment, the support block is provided with a second abutment plane that is adapted to the first abutment plane.
[0018] In one embodiment, the second guide block is provided with a second abutting slope that is adapted to the upper twisted slope.

[0042] Please see Figure 2 The present invention provides a stepping die twisting mechanism 100, which includes an upper twisting module 10, a lower twisting module 20, a floating block 30, and a telescopic rod 40. The upper twisting module 10 and the lower twisting module 20 are arranged opposite each other vertically. The floating block 30 is movably disposed on the lower twisting module 20. The lower end of the floating block 30 is fixedly connected to the telescopic end of the telescopic rod 40.
[0043] Please see Figure 3 The lower end of the upper twisting module 10 is provided with a first abutting plane 11 and an upper twisting inclined surface 12. There are two upper twisting inclined surfaces 12, which are respectively located on both sides of the first abutting plane 11 and are inclined downwards towards each other. The upper twisting module 10 is provided with a positioning post 13.
[0044] Please see Figure 4 The lower twisting module 20 includes a main body 21 and a mounting part 22 connected to the main body 21. A first supporting plane 23 is provided at the upper end of the main body 21. A mounting groove 24 is provided between the mounting part 22 and the main body 21. A through groove is provided on the mounting part 22. There are two lower twisting modules 20, which are spaced apart.
[0045] Please see Figure 4 The floating block 30 is movably inserted into the through slot. The top of the floating block 30 is provided with a second supporting plane 31 and a first abutting inclined plane 32 adapted to the upper twisting inclined plane 12. Before the upper and lower molds are pressed together, both the first supporting plane 23 and the second supporting plane 31 abut against the workpiece 300 to support it and balance its forces. Each floating block 30 corresponds to one of the lower twisting modules 20, and each telescopic rod 40 corresponds to one of the floating blocks 30.
[0046] Please see Figure 2 and Figure 4The stepping die twisting mechanism 100 further includes a support block 50, which is movably disposed between the two lower twisting modules 20. The lower end of the support block 50 is fixedly connected to the telescopic end of the telescopic rod 40. Each support block 50 corresponds to one telescopic rod 40. The support block 50 is provided with a second abutment surface 51 adapted to the first abutment surface 11. The cooperation between the first abutment surface 11 and the second abutment surface 51 clamps the strip 200, preventing displacement and improving twisting quality. The support block 50 is provided with a positioning hole 52 adapted to the positioning post 13. The cooperation between the positioning post 13 and the positioning hole 52 further ensures that the strip 200 will not shift, improving twisting quality.
[0047] Please see Figure 2 and Figure 4 The stepping mold twisting mechanism 100 further includes a first guide block 60, which is fixedly installed in the mounting groove 24. The first guide block 60 is provided with a first guide groove 61, which communicates with the through groove. The first guide block 60 corresponds one-to-one with the lower twisting module 20. The floating block 30 can move up and down through the first guide groove 61.
[0048] Please see Figure 2 and Figure 4 The stepping die twisting mechanism 100 further includes a second guide block 70, which is disposed between the support block 50 and the lower twisting module 20. The second guide block 70 has a second abutting inclined surface 71 adapted to the upper twisting inclined surface 12. There are two second guide blocks 70, and a second guide groove adapted to the support block 50 is provided between the two second guide blocks 70. The support block 50 can move up and down through the second guide groove.
[0049] The working principle of the stepping die twisting mechanism 100 in this embodiment is as follows: Initially, the strip 200 is placed on the lower twisting module 20, the first support plane 23 and the second support plane 31 abut against the workpiece 300, and the second abutting plane 51 abuts against the strip 200, providing support for the strip 200. During the pressing process, the upper twisting module 10 moves downward, and the positioning post 13 engages in the positioning hole 52. Simultaneously, the first abutment surface and the second abutment surface cooperate to clamp the material strip 200. The upper twisting module 10 continues to move downward, and the support block 50 and the floating block 30 move downward accordingly. The upper twisting inclined surface 12, the first abutment inclined surface 32, and the second abutment inclined surface 71 cooperate to complete the twisting of the material strip 200. Before and during the pressing process, the material strip 200 is always supported, effectively preventing the connection between the material strip 200 and the workpiece 300 from breaking due to excessive impact force during the pressing process. This effectively improves the yield rate and thus improves production quality.
[0050] During mold opening, the support block 50 and the floating block 30 move upward with the material strip 200 and the workpiece 300 under the action of the telescopic rod 40, so as to quickly demold the material strip 200.
[0051] The beneficial effects of this utility model are as follows: With the cooperation of the upper twisting module 10, the lower twisting module 20, the floating block 30 and the telescopic rod 40, the material strip 200 and the workpiece 300 can be supported before and during the pressing process. This can effectively prevent the connection between the material strip 200 and the workpiece 300 from breaking due to excessive impact force during pressing, thereby effectively improving the yield rate and thus improving production quality.
[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
