一、概述在电器产品中,冲压件所占比重很大,特别是有色金属用量很多。为了降低产品成本,除尽量用黑色金属代替有色金属外,另一途径就是提高冲压件的材料利用率。如图1a所示零件,一般常采用单冲模,将板料切成条料,再进行冲裁。 First, an overview In electrical products, a large proportion of stamping parts, in particular, a lot of non-ferrous metals. In order to reduce product costs, in addition to using non-ferrous metals instead of ferrous metals as much as possible, the other way is to improve the material utilization of stamping parts. As shown in Figure 1a parts, usually single punch, the sheet cut into strips, and then punching.
