制造冲裁模时究竟应先加工凸模还是先加工凹模?极少数模具厂在任何情况下都先加工凸模或都先加工凹模,而大多数厂家是从工艺及经济角度来决定两者的先后顺序的。现将有关经验汇集如下:如果冲裁轮廓为简单而规则的圆形(如图a),则凸模、凹模可分别加工,因此,就不存在先加工哪个的问题,但要保证后者与前者准确地。对中。如果冲裁轮廓在圆形的基础上稍有变化,则凸、凹模加工的先后取决于
When manufacturing blanking die, should the first punch or die processing first? Very few mold factory in any case, the first punch or die processing are the first, and most manufacturers from the technical and economic point of view to determine the two The order of the person. The relevant experience is summarized as follows: If the blanking contour is a simple and regular circular (Figure a), then the punch and die can be processed separately, so there is no problem in the first processing, but to ensure that the latter With the former accurately. Right. If the blanking profile on the basis of a slight change in the circle, then the convex and concave mold processing depends on
