数字程序控制电火花线切割机床在模具行业中的广泛应用,给模具生产带来了巨大的变化,促进了模具技术的发展。线切割加工冲裁模的凹模时,一般都有一块内孔的“废料”,为利用这块中间切下的废料,用作凸模和凸凹模的新方法,一般称之为:“从凹模中取凸模和凸凹模”,实践证明,这一方法具有简化工装设计,节省工具钢材料,减少工时,缩短模具制造周期和降低成本等优点。一、各种典型冲裁零件和模具 Digital program control WEDM widely used in the mold industry, to mold production has brought tremendous changes, and promote the development of mold technology. Wire cutting die when the die cavity, the hole generally have a “waste”, in order to use this piece of cutting the middle of the waste, as a new method of punch and punch and die, commonly known as: “From Take the punch and punch punch and die ”Practice has proved that this method has the advantages of simplified tooling design, tool steel savings, reduce working hours, shorten the mold manufacturing cycle and reduce costs. First, all kinds of typical blanking parts and molds
