1、摘要冲压模具技术作为模具制造业中最重要的组成部分，机械、电子、轻工业等大量使用了冲压零件，所以冲压模具技术水平的高低，发展前景的好坏直接影响到整个制造业的发展。随着经济的高速发展对模具工业提出了越来越高的要求，也为其发展提供了巨大的动力。复合冲压模的特点是生产率高，冲裁件的孔与外缘的相对位置精度高，本制件为小尺寸平板冲裁件，要求平整、料厚很小，且要求大批量生产，故采用顺装式复合冲裁模。凹模采用镶拼结构，不但加工方便而且节省材料。为了使加工平稳，模具采用中间导柱。本复合模，采用了冲孔和落料两个工序进行冲压。该套冲压模具设计周密，设计容全面。包括对冲压件工艺性分析，模具工艺方案的确
2、定，模具零件的设计、受力计算及其校核，模具标准的选定，装配图的绘制，压力机的型号选定，零件加工工艺的确定等，并综合考虑分析横排、对排、斜排等各种排样方式的优缺点和适应性，最后以最高效率、最低成本、最高质量、最简结构来确定排样和模具的结构，这样的模具操作更加安全、快捷、方便，并且更容易达到冲压件的公差等级要求等。实现了冲压模具用材节省、结构合理、精度高、操作方便等优点。关键词：顺装复合模；排样；落料；冲孔；镶拼结构AbstractThetechnologyofstamping dieasthemostimportantcomponentofthediemanufacturing,
