[0026] Specifically, the slide rail 12 supports the sliding of the slider 13. The slider 13 is used to fix the clamping machine 14. The clamping machine 14 is an existing structure, mainly used to drive the buckle 15 into the slot 16 for fixation. It will not be described in detail here. The fixing post 9 has a slot 16 to hold the buckle 15 for fixation. The lower mold base 1 is used to fix the die 18. The die 18 is used to hold the copper strip body 19 for drilling.

When the sliding sleeve 4 slides downwards, it causes the support column 6 to slide. When the support column 6 slides downwards, it causes the pad 8 to slide. When the pad 8 slides downwards, it causes the fixing column 9 to slide. When the fixing column 9 slides downwards, it causes the punch 17 to punch holes in the copper strip body 19. The outer material of the copper strip body 19 uses a diamond nano-coating material, thus... To improve the wear resistance of punch 17 and reduce the cost increase caused by wear, when punch 17 needs to be disassembled, first start clamping machine 14, which drives buckle 15 to slide. When buckle 15 slides, it will leave the slot 16. Then, pull the fixing post 9 out of the backing plate 8. This allows for quick disassembly of punch 17, making it convenient for maintenance personnel to quickly disassemble and replace, and shortening the maintenance time of the mold. Finally, using this device can not only avoid the reduction of dimensional accuracy of punch 17 due to wear, but also make the replacement and maintenance of punch 17 more convenient.
