Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and more specifically, to a stamping die cutting and forming punch. Background Technology

[0002] A die punch is a metal part on a stamping die in a machine tool. It is also called a punch, punch needle, or punch. It is installed on a stamping die to perform continuous punching, stamping, and cutting operations, causing the processed material to separate or plastically deform, thereby obtaining the desired finished or semi-finished product.

[0003] For example, existing patent CN216095845U discloses a water-expanding die punch structure. When the end of the valve pin abuts against the end of the punch, it seals the shaft hole, thus sealing the water inlet and maintaining pressure within the die cavity. This solves the problem of unstable product dimensions and the likelihood of defective products caused by unstable water pressure within the die cavity when stainless steel pipes are water-expanded. However, when changing die punches, the entire punch needs to be disassembled. Since punches on stamping dies are mostly fixed with nuts and bolts, this installation method is slow because it requires replacing the entire punch and disassembling many parts, resulting in slow changeover time, reduced production efficiency, and increased risk of punch damage. Furthermore, the punch body is difficult to disassemble and replace, affecting the stamping effect and limiting its application.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
