摘　　要：以微小碟形件作为目标零件,研究微冲裁及微拉深复合成形工艺,设计相应的微冲裁冲压复合模具。在一次冲裁行程中完成浅半球拉深、冲孔及落料等过程,可减小分步成形所带来的多次定位安装误差,节省加工工时及模具制造成本,从而降低微小碟形件特征结构的位置偏差,实现微小碟形件的高精度、高效率加工;同时,复合成形易保证零件特征尺寸的一致性。Aiming at the property of the micro dish-shaped parts ,a combining micro blanking process with micro deep drawing process is studied ,and the corresponding composite mold is designed. The processes of shallow hemisphere drawing ,punching and blanking are accomplished in only one blanking stroke,which can reduce the positioning and installation tolerances,processing time and manufacturing cost of mold with multi-step forming. The method decrease position deviation of micro dish-shaped parts′ feature structure,so as to achieve high quality and high efficiency way to manufacture micro dish-shaped parts ,and easy to ensure the consistency of the part feature size with composite molding process.
