上一期所举的硅钢片落料冲孔模的例,是多工位级进模中最简单的,它基本还是跳步模的形式,只不过多用了一些导正销。这个例子主要是说明冲裁力中心的位置与凹模的安排的关系。 多工位级进模与跳步模的最大区别是冲成的制件不是用最后落料方式来完成的。这主要是因为采取落料方式,落料凸模必须和制件的外形轮廓一致(或基本一致);而这 The last period of silicon steel blanking punching die example is multi-station progressive die in the most simple, it is basically the form of jumping mode, but with some more Pilot Punches. This example mainly shows the relationship between the position of the center of the punch and the arrangement of the die. The biggest difference between multi-stage progressive die and skip step is that the finished parts are not finished by the last blanking method. This is mainly because of the blanking method, blanking punch must be consistent with the contour of the workpiece (or substantially the same); and
