摘要 机械产品的连接板大部分是冲压制品，产品性能的提高要求高素质的冲压模具、冲压性能、成型工艺和冲压制品的设计。冷冲裁模，约占冲压成型总数的60%，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。冲压成型的广泛应用，正是本设计的根本出发点。 本来源于生产实际，主要任务是完成连接板的冲压模具设计和制造仿真。通过多种方案对比，本设计采用连续模结构，模具中设置了冲孔、倒角、落料等工位。设计中通过对连接板的材料、形状、尺寸及其精度的要求进行冲压工艺分析，结合工艺可行性分析，将零件展开，设计了排样图；根据工艺计算结果，对模具主要零部件，如凸、凹模和凸模固定板等进行详细设计，并设计了连接板的连续模。在设计中对模具的总体结构进行设计，包括上下模座、导柱导套、垫板、固定板、导料板、卸料板、卸料板弹钉等的设计与选用。利用Auto CAD2004软件制作了此连续模模具的装配图和零件图。 关键词：连续模；冲孔；折弯 Aabstract Most of mecha
