DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0016] Embodiment: As Figures 1-4As shown in the figure, the present utility model provides a metal stamping die, which includes a workbench 1. A base 11 is fixedly installed at the bottom end of the workbench 1. A lower die 12 is provided at the top end of the base 11. Guide rods 13 are fixedly installed at the four corners of the top end of the base 11. A top plate 14 is fixedly installed at the top end of the guide rods 13. A hydraulic telescopic rod 15 is fixedly installed at the top end of the top plate 14. An installation plate 16 is fixedly installed at the driving end of the hydraulic telescopic rod 15. An upper die 17 is fixedly installed at the bottom end of the installation plate 16. A stamping head 18 is fixedly installed at the bottom end of the upper die 17. A pressing groove 19 corresponding to the stamping head 18 is opened at the top end of the lower die 12. First connecting plates 2 are fixedly installed on both sides of the lower die 12. The first connecting plates 2 are located at the edge of the lower die 12. Two symmetrically distributed first empty slots 21 are penetrated and opened at the top end of each first connecting plate 2. A threaded rod 22 corresponding to the first empty slot 21 is threadedly connected to the upper surface of the base 11. Each threaded rod 22 penetrates through the corresponding first empty slot 21. A fixing plate 23 is fixedly installed at the top end of the threaded rod 22. A diamond-shaped block 24 is fixedly installed at the top end of the fixing plate 23. The length and width of the fixing plate 23 are smaller than the length and width of the first empty slot 21, which is more convenient for the first empty slot 21 on the first connecting plate 2 to quickly pass through the corresponding fixing plate 23. The installation plate 16 is slidably sleeved on the guide rod 13. By setting the guide rod 13, when the installation plate 16 and the upper die 17 move downward, they are more stable.

[0017] A second empty slot 3 is opened at the top end of the lower die 12 below the pressing groove 19. Two symmetrically distributed springs 31 are fixedly installed on the lower surface of the inner wall of the second empty slot 3. A second connecting plate 32 is fixedly installed at the top end of the spring 31. A spring plate 33 is fixedly installed at the top end of the second connecting plate 32.

[0018] Two symmetrically distributed shock-absorbing air bags 34 are fixedly installed between the second connecting plate 32 and the second empty slot 3. Two symmetrically distributed telescopic rods 35 are fixedly installed between the second connecting plate 32 and the second empty slot 3. Each spring 31 is sleeved on the corresponding telescopic rod 35. By setting the shock-absorbing air bags 34 and the telescopic rods 35, when the spring 31 drives the second connecting plate 32 and the spring plate 33 to rebound, it is more stable.

[0019] Two symmetrically distributed L-shaped fixing blocks 36 are fixedly installed at the bottom end of the second connecting plate 32. The L-shaped fixing blocks 36 are located at the edge of the second connecting plate 32. Limiting grooves 37 are opened on both sides of the inside of the lower die 12 where the second empty slot 3 is located. The L-shaped fixing blocks 36 are slidably clamped in the corresponding limiting grooves 37. By setting the L-shaped fixing blocks 36 and the limiting grooves 37, the second connecting plate 32 and the spring plate 33 are limited when they rebound. At the same time, the stability of the second connecting plate 32 and the spring plate 33 when they rebound is increased.

[0020] At the top of the lower die 12, there are two symmetrically distributed placement grooves 4. By providing the placement grooves 4, it is more convenient to stamp the hardware parts to be stamped. At the same time, by providing two placement grooves 4, multiple hardware parts can be stamped simultaneously, improving work efficiency.

[0021] Working principle: In actual use, pass the first empty groove 21 in the first connecting plate 2 on the lower die 12 through the corresponding threaded rod 22, fixing plate 23, and diamond-shaped block 24, so that the lower die 12 and the first connecting plate 2 are attached to the base 11. Then, by rotating the diamond-shaped block 24, drive the fixing plate 23 and the threaded rod 22 to rotate. The threaded connection between the threaded rod 22 and the base 11 causes the fixing plate 23 to move downward, making the fixing plate 23 and the first connecting plate 2 fit. At the same time, the fixing plate 23 and the corresponding first empty groove 21 are in a cross shape, thereby fixing the lower die 12 on the base 11.

[0022] After the lower die 12 is fixed, place the hardware to be stamped on the placement groove 4. Then start the hydraulic telescopic rod 15 to drive the mounting plate 16, upper die 17, and stamping head 18 to move downward, so that the stamping head 18 stamps the hardware. When stamping the hardware, the elastic plate 33, second connecting plate 32, and spring 31 move downward. Then, after the hardware stamping is completed, under the action of the spring 31, drive the elastic plate 33, second connecting plate 32, and the stamped hardware to eject from the pressing groove 19, and then manually pick up the ejected hardware.

[0023] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these changes and modifications.
