为了缩短模具加工周期,减少加工费用,在冲裁模具制造中用同一块钢材一次加工出凸模和凹模的生产方法就显出了其很大的优越性。我们在这方面也作了一些探讨与同行们共同研究。采用凸、凹模同时加工工艺时,我们可以按凸,凹模所需要的间隙分为下面三种情况。 In order to shorten the mold processing cycle, reduce the processing cost, in the stamping die manufacturing with the same piece of steel processing a punch and die production methods have shown its great superiority. We have also made some discussions in this area with our colleagues for their joint study. The use of convex, concave die at the same time processing technology, we can press the convex die required gap is divided into the following three cases.
