摘要
介绍在凸模端面加设锥度 ,在侧面加设刃带的方法 ,消除了凸模被镦粗而卡料的可能 ,同时减少了凸模侧面与冲件的接触面积 ,减少了卸料力 ,从而改善凸模受力 。
A method was introduced to eliminate the possibility of the punch seizing the material due to being upset, by adding a coning at the end surface of the punch and adding a point zone at the side surface. Meanwhile, the contact area between the side surface of the punch and the workpiece was reduced, and the stripping force was reduced, that thus improved the stress exerted on the punch and extended the die life.
