AI Technical Summary
The replacement process of punches and dies in existing stamping dies is cumbersome, requiring the disassembly and tightening of multiple bolts, resulting in long replacement times and affecting ease of use.
The quick-change stamping die adopts a punch and die combination structure. Through the matching insertion of the positioning mounting hole and the fixing rod, the interference fit between the limiting part of the insertion part and the insertion cavity of the fixing rod, and the axial limiting of the clamping part, the die and punch can be quickly changed, simplifying the operation process.
No need to disassemble and tighten multiple bolts; mold replacement can be completed simply by plugging and unplugging connectors, shortening replacement time and improving ease of use. Furthermore, roller guidance and elastic cotton cushioning ensure the stability of the die cavity and reduce the impact force during mold closing.
