传统的冲裁模制造一般需26道工序(凸模+凹模),按本方案只要8道工序,少数的需要16道工序。其做法是:改变冲模结构。使好钢用在刀刃上;对刃口部分采取锻造余热淬火;将常规热处理、刨、铣等加工都取消;并用线切割割凸,凹模一次成型;从而使制造速度快一倍以上,质量比以前更 The traditional blanking die manufacturing process generally takes 26 (punch + die), according to the program as long as 8 procedures, a few need 16 procedures. The practice is: to change the die structure. So that good steel used in the blade edge; on the edge part of the forging heat quench; the conventional heat treatment, planing, milling and other processing are canceled; and cut with a convex line, a die forming; so that the manufacturing speed more than doubled, the quality of More than ever before
