一、前言在电器、仪表产品元件的冲压生产中,有一些冲裁件的尺寸很小,几何形状复杂,厚度为0.01～0.5毫米的薄料,而且多数为有色金属,要求模具间隙小。这对于目前常规结构的复合冲裁模来说,给模具制造带来很多困难。另一方面,绝大部分的机床均是“C”形开式冲床,精度与刚性都很差。这对用一般复合冲 I. Preface In stamping production of electrical appliances and instrumentation products, there are some punching parts of small size, complicated geometrical shapes and thin materials with a thickness of 0.01 to 0.5 mm, and most of them are non-ferrous metals, requiring a small mold clearance. This is the current conventional structure of the composite blanking die, mold manufacturing to bring a lot of difficulties. On the other hand, the vast majority of machine tools are “C” -shaped open punches with poor precision and rigidity. This is the general composite red
