1、支架零件冲压与冲模设计摘 要摘摘 要要 冲压制品已在工业、农业、国防和日常生活中的方面得到广泛应用,特别是在机械业中更为突出。机械产品的外壳大部分是冲压制品，产品性能的提高要求高质量的冲压模具和冲压性能，成型工艺和制品的设计。冲压制品的成型方法很多。其主要用于是冲孔，落料，弯曲，拉伸等。而冲压模，约占成型总数的 60以上。当然如利用电气控制，可实现半自动化或自动化作业。冷冲冲裁模主要用于金属制品的成型，它是冲压制品生产中十分重要的工艺装置。冲压模的基本组成是：上下模座、下模垫板、下模固定板、凹模镶块、抬料钉、导料板、卸料板,导柱导套、卸料板弹钉、卸料板等。通过对冲裁图样零件的工艺性的正确分析，
2、设计了一个连续冲裁冲孔落料模。本设计介绍了模具成型零件包括凸模、凹模及其他零件如卸料板、固定板、垫板、导柱、导套等的设计和选用过程，重要零件的工艺参数的选择与计算，冲裁机构与送料挡料以及其它结构的设计过程，并对着重对模具的设计部分作了详细介绍。关键词关键词 冲孔 落料 复合模 冲孔落料模 支架零件冲压与冲模设计iThe blanking dies design of fixed plateAbstract: Stamping products has been extensively applied in the industry, agriculture, national defense
