Abstract：
|
|
A composite die for clip-blanking,punching and bending was designed according to the structure and specifications of clamping pieces by considering how to guarantee product quality,improve production efficiency and simplify die construction simultaneously.The key of this design was to adopt a mobile bending concave die and a backing out punch which also acted as a male bending die.By the advance and retreat of the concave die,the traditional sub-module processing was combined into one process by integrating blanking,punching and bending in one step.This design can guarantee quality,reduce costs and improve productivity.
