图1为静触片冲件,外形复杂、孔小、精度高。原采用落料、冲孔、压弯、压花四道工序分别由四付模具冲出。工效低,最后压花工序使零件上部宽度尺寸变大。 Figure 1 is a static contact piece stamping, complex shape, small hole, high precision. The original blanking, punching, bending, embossing four processes were punched out by four to pay the mold. Work efficiency is low, the last embossed process to make the upper part of the width size becomes larger.
