摘要 随着科技的发展，模具在我们的社会生活中越来越重要，模具已经深入我们生产生活中。模具生产出来的产品会比模具本身价值高很多，只要设计出一套模具，产品就会源源不断的生产出来，所以，很多企业公司都会采用模具成形技术生产产品。 防转片在机械运转中主要起防止相邻部件的相对转动的作用。本文主要介绍了防旋落料复合模具的设计。从零件的可加工性分析开始，分析和比较各种加工方案，以确定最佳的加工方案。内容还包括零件工艺计算方面包括刃口尺寸计算，排样计算，冲压力计算，标准模架的选用，卸载装置中弹性部件的计算决定了其他部件的结构，并绘制了模具装配图和模具部件图。此次设计让我对模具知识以及机械行业有了更深了认识，同时锻炼了自行设计的能力。 关键词;防转片；复合模；模具设计 Abstract With the developme
