[0004] In existing technologies, because steel is in a state of frequent movement and cannot be fixed, the large impact force of the drill bit during stamping can cause the steel to shift, resulting in poor stamping results. This can lead to problems such as inaccurate part dimensions, shape deformation, and reduced surface quality, affecting the assembly and performance of the product, and also damaging the stamping equipment and molds. Therefore, an automated stamping mold for motor gearboxes is proposed to solve the above problems. Utility Model Content

[0012] As a further description of the above technical solution:
[0013] The inner wall of the base is fixedly connected to a telescopic column, and the top of the telescopic column is fixedly connected to a toothed plate.
[0014] As a further description of the above technical solution:
[0015] The outer side of the toothed gear is meshed with the outer side of the toothed plate, and the top of the toothed plate is fixedly connected to the inner wall of the lifting box.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figure 2 and Figure 3 This utility model provides an embodiment of an automated stamping die with a motor gearbox, comprising a base 1. A drive assembly for maintaining the stability of the workpiece during stamping is fixedly connected to the inner wall of the base 1. The drive assembly includes a drive motor 2, externally mounted on the inner wall of the base 1. A gear 3 is fixedly connected to the drive end of the drive motor 2. Starting the drive motor 2 causes the gear 3 to rotate. A telescopic column 4 is fixedly connected to the inner wall of the base 1, and a toothed plate 5 is fixedly connected to the top of the telescopic column 4. The telescopic column 4 helps maintain stability during the movement of the toothed plate 5. A lifting box 6 is fixedly connected to the outside of the drive assembly, enabling the drive assembly to move the lifting box 6. The outside of the gear 3 is meshed with the outside of the toothed plate 5, and the rotation of the gear 3 causes the toothed plate 5 to rise or fall. The top of the toothed plate 5 is fixedly connected to the inner wall of the lifting box 6, and the positional change of the toothed plate 5 causes the positional change of the lifting box 6.
[0035] Reference Figure 2 and Figure 4 A support assembly for supporting and fixing a stable structure is fixedly connected to the top of the base 1. The support assembly includes a support frame 7, the bottom of which is fixedly connected to the top of the base 1. Multiple telescopic rods 8 are fixedly connected to the top of the support frame 7, and the support frame 7 serves to fix the positions of the multiple telescopic rods 8. The tops of the multiple telescopic rods 8 are fixedly connected to the bottom of the top plate 9. When the top plate 9 rises or falls, the multiple telescopic rods 8 are used to maintain the stability of the top plate 9. The top of the support assembly is fixedly connected to the top plate 9. The exterior of the lifting box 6 is in contact with the bottom of the top plate 9. Changes in the position of the lifting box 6 cause changes in the position of the top plate 9. A fixing rod 10 is fixedly connected to the bottom of the top plate 9. Changes in the position of the top plate 9 cause changes in the position of the fixing rod 10.
[0036] A positioning plate 11 is fixedly connected to the outside of the fixing rod 10. Changes in the position of the fixing rod 10 cause changes in the position of the positioning plate 11. Multiple fixing posts 12 are fixedly connected to the bottom of the positioning plate 11. Changes in the position of the positioning plate 11 cause changes in the position of the multiple fixing posts 12. A spring 13 (as shown in the attached image) is fixedly connected to the inner wall of each fixing post 12. Figure 4The fixed post 12 fixes one end of the spring 13, allowing the spring 13 to return to its original position smoothly. The other end of the spring 13 is fixedly connected to a sliding post 14; movement of the sliding post 14 causes deformation of the spring 13. A pressure plate 24 is fixedly connected to the bottom of each sliding post 14; movement of the sliding post 14 causes movement of the pressure plate 24.
[0037] Reference Figure 1 , Figure 2 and Figure 5 A fixing strip 16 is fixedly connected to the outside of the top plate 9. Changes in the position of the top plate 9 cause the fixing strip 16 to move upwards. A fixing plate 15 is fixedly connected to the top of the base 1. A rotating block 17 is rotatably connected to the outside of the fixing plate 15. The fixing plate 15 has a function of fixing the rotational position of the rotating block 17 at its center. One end of the rotating block 17 is movably connected to the inner wall of the fixing strip 16. Changes in the position of the fixing strip 16 can cause one end of the rotating block 17 to change position.
[0038] The other end of the rotating block 17 is fixedly connected to a linkage block 18. Changes in the position of the rotating block 17 cause changes in the position of the linkage block 18. The other end of the linkage block 18 is fixedly connected to a locking block 19 (as shown in the attached figure). Figure 5 The positional change of the linkage block 18 causes the positional change of the locking block 19. A steel member 23 is slidably connected to the inner wall of the support frame 7, and the support frame 7 limits the movement of the steel member 23. The outer side of the locking block 19 is in contact with the inner wall of the steel member 23, and the positional change of the locking block 19 can cause the steel member 23 to move in one direction.
[0039] Reference Figure 6 A damper 21 is fixedly connected to the inner wall of the base 1, and a lower die 20 is fixedly connected to the top of the damper 21, so that the lower die 20 can remain stable when subjected to stamping. A plurality of springs 22 are fixedly connected to the inner wall of the base 1, and the other end of the plurality of springs 22 is fixedly connected to the bottom of the lower die 20, providing space for the lower die 20 to move. The positional change of the lower die 20 can drive the positional change of the plurality of springs 22, and the reset of the plurality of springs 22 can drive the reset of the lower die 20.
[0040] Working principle: When the drive motor 2 is started, the position change of the drive end of the drive motor 2 causes the toothed gear 3 to rotate. The rotation of the toothed gear 3 causes the toothed plate 5 to move. The position change of the toothed plate 5 causes the lifting box 6 to move. The position change of the lifting box 6 causes the top plate 9 to move. The position change of the top plate 9 causes the fixing rod 10 to move. The position change of the fixing rod 10 causes the positioning plate 11 to move. The position change of the positioning plate 11 causes the fixing column 12 to move downward. The position change of the fixing column 12 causes the sliding column 14 to move downward. The position changes of multiple sliding columns 14 cause the pressure... The plate 24 presses against the material surface. When the pressure plate 24 approaches the material surface, it moves in the opposite direction, causing the positions of multiple sliding columns 14 to change. This causes multiple springs 13 to deform and then return to their original positions, allowing the springs 13 to exert pressure on the sliding columns 14. This ensures that the surface of the pressure plate 24 is in close contact with the material. The surface of the fixing rod 10 is a stamping structure, which can cooperate with the lower die 20 to complete the stamping. During stamping, the stable workpiece position ensures processing accuracy, making the size and shape of the stamped parts closer to the design requirements, improving product quality consistency, reducing the scrap rate caused by position changes, and lowering production costs.
[0041] The positional change of the top plate 9 causes the fixed strip 16 to change position. The positional change of the fixed strip 16 can cause one end of the rotating block 17 to change position. The rotation of the center of the rotating block 17 causes the other end to change position, thereby causing the linkage block 18 to change position. The positional change of the linkage block 18 can cause the locking block 19 to change position, so that the locking block 19 can push the steel 23 to change position. When processing the workpiece, the material position is moved while stamping, which can avoid wasting time due to frequent stops to change the material position. This makes the entire processing flow more compact and continuous. By continuously and stably moving the material, the stamping pressure, the point of application, and other conditions can be made relatively uniform, reducing the error caused by the change of material position.
