某型号角架冲压工艺分析及冲压模具设计 摘要 模具在现代工业生产占有重要地位，有“工业之母”的美称。而冲压在整个模具行业担任重要的角色，发展迅速极其之快。冲裁是利用模具使板料产生分离的冲压工序，包含落料，冲孔，成型，翻边。冲压技术被广泛应用在汽车，航空，船舶，家电领域。他在人们日常中占据很重要的地位。 本设计是关于角架的冲压模具设计，首先对角架的冲压工艺进行分析，通过分析对比，确认冲压的工艺方案和模具结构类型，并且，完成其工位排版等设计问题最终完成角架的二维图，三维立体图。将所有的参数计算完成后，要对模具的整体装配方案，装配的技术要求进行分析，以便清晰地表达出角架的冲压加工过程。 关键词：角架；冲压；落料；冲孔； Abstract Mold i
