Description

Technical Field

[0001] The utility model relates to the technical field of fuze processing and manufacturing, in particular to a fuze component bipolar piece mold. Background Art

[0002] A fuze is a device used in ammunition that is designed to detonate or apply a force to ignite, detonate or deflagrate a charge under specific conditions. The most common use is to detonate or release its contents when its detonation conditions are met. Fuzes usually contain electronic or mechanical elements that are used to send a detonator signal or activate the detonator. Some fuzes also contain a small amount of primary explosive.

[0003] The actual size of the fuze parts is small, and the shape and size accuracy requirements are high. For some parts with small holes, the life of the small hole punch is much shorter than that of the large hole punch. When the punch breaks, a new mold needs to be replaced, which greatly increases the mold processing cost. When processing the hole, the mold is only guided by the outer guide pin and the outer guide sleeve, and it is difficult to ensure the forming quality of the part.

[0004] Therefore, it is necessary to design a reasonable mold structure to improve the mold service life and part accuracy, and to achieve efficient mold manufacturing and maintenance. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides as Figure 1A fuse part stamping die as shown includes an upper die base 13, an inner guide bushing 23, an inner guide pillar 26, a Ф26×50 outer guide bushing 15, a Ф24×50 outer guide bushing 19, an outer guide pillar 21, a guide pillar fixing part 17 and an M8×24 socket head cap screw 18. The outer guide pillar 21 and the guide pillar fixing part 17 are fixedly connected by the M8×24 socket head cap screw 18. The Ф24×50 outer guide bushing 19 is sleeved on the outer wall of the outer guide pillar 21. The upper die base 13 is connected through the Ф26×50 outer guide bushing 15 and the Ф24×50 outer guide bushing 19. A vacancy plate 10 is arranged on the bottom outer wall of the upper die base 13. There is a through groove in the middle of the vacancy plate 10. A transmission top plate 11 is arranged. The transmission top plate 11 is linked to the upper die base 13 through a spring 12. A blanking rod is arranged on the bottom outer wall of the transmission top plate 11. A punch pad 20 is arranged on the bottom outer wall of the vacancy plate 10. A punch fixing plate 7 is arranged on the bottom outer wall of the punch pad 20. A blanking die fixing plate 5 and a blanking die 6 are arranged on the bottom outer wall of the punch fixing plate 7. The upper die base 13 is fixedly connected to the blanking die fixing plate 5 through an M8×16 socket head cap screw 16. The blanking die 6 is fixedly connected to the blanking die fixing plate 5 through semi-pin holes. A ejector block 22 is arranged inside the blanking die 6. In the upper part of the lower die base 1, there is a groove in the middle and a convex and concave die pad 28 is arranged. The lower die base 1 is fixedly connected to a convex and concave die fixing plate 27 through an M8×12 socket head cap screw 29. Rubber 25 is arranged on the top outer wall of the convex and concave die fixing plate 27. There are a pin hole for installing a stop pin and a channel for the convex and concave die 24 inside the rubber 25. A blanking plate 4 is arranged on the top outer wall of the rubber 25. The convex and concave die fixing plate 27 is fixedly connected to the blanking plate 4 through an M6×12 socket head cap screw 3. Fixed pin holes, punching and blanking holes and forming and blanking holes are arranged on the convex and concave die 24. The punching and blanking hole is located directly below the punching punch. The inner guide bushing 23 is fixed inside the blanking die fixing plate 5 through a stepped groove. Inner guide pillar channels are arranged in the convex and concave die fixing plate 27, the punch fixing plate 7, the rubber 25 and the blanking plate 4. The inner guide pillar 26 is fixed inside the lower die base 1 through a trapezoidal groove. The original material of the fuse part is placed on the top outer wall of the convex and concave die 24. The upper die base 13 moves downward through inner guiding and outer guiding. The punching small punch 8 and the large punch 9 move downward to punch holes of different sizes on the original material of the fuse part. Compared with the large punch 9, the punching size of the small punch 8 is small. When the small punch 8 punches the original material of the fuse part, the punch part is prone to breakage. The small punch 8 and the large punch 9 adopt an insert structure and are respectively fixed inside the punch fixing plate 7. The small punch 8 is fixed inside the punch fixing plate 7 through a stepped groove. A pin through hole is arranged in the middle of the large punch 9 and is fixed to the punch fixing plate 7 through a pin. Thus, when the small punch 8 breaks, only the broken small punch 8 needs to be replaced, greatly improving the replacement efficiency of the die and saving the die processing cost.

[0023] Such as Figure 1As shown, the inner guide sleeve 23 is fixed inside the blanking die fixing plate 5 through a stepped groove, and inner guide column channels are provided inside the male and female die fixing plates 27, the male die fixing plates 7, the rubber 25 and the unloading plate 4. The inner guide column 26 is fixed to the lower die seat 1 through a trapezoidal groove. When the upper die moves downward to blank and punch the raw material of the fuze part, the die is guided not only by the external guide columns and guide sleeves, but also by the internal guide sleeve 23 and the internal guide column 26, so that the precision of the processed parts is higher and the processing quality of the parts is guaranteed.

[0024] like Figure 1 As shown, a die handle 14 is provided in the middle of the upper die base 13, and the upper die base 13 is fixed to the die handle 14 by a hexagon socket screw. The device is installed on the punching machine through the die handle 14. The upper die base 13 and the transmission top plate 11 are connected by a spring 12, and a rubber 25 is installed between the unloading plate 4 and the male and female die fixing plate 27. When the upper die descends to punch the raw material of the fuze part, the lower die is fixed, and the male and female dies 24 punch out the part shape, pushing the unloading block 22 upward, and the spring 12 is compressed through the driving rod, and the male and female die fixing plate 5 descends to squeeze the unloading plate 4, causing the rubber 25 to be compressed. After the stamping is completed, the upper die ascends, and the spring 12 and the rubber 25 automatically rebound to unload, thereby realizing automatic generation, greatly accelerating the generation efficiency and reducing labor costs.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
