踏板组件（B）冲压模具设计 摘要 此设计说明书的内容里，包含有两个方面的内容，其一是有关模具的主要发展形势，其二是我对于踏板组件的冲压模具设计介绍。我主要负责设计的是该U型件的冲孔、落料工序，用复合模完成该部分工序的生产。首先考虑了产品的质量要求和生产的实际情况，确定了最佳工艺方案，同时计算下料展开尺寸和零件压力中心，计算模具中的凸凹模刃口尺寸，校核凸模强度以及压力机的核查，精确详细地对有关工艺参数进行计算，准确无误的选择压力设备，同时对模具零件的结构进行设计，适应了目前冲压模具的设计要求。然后进行冲压模具设计，全部采用AutoCAD软件进行图样设计，绘制出了二维装配图和零件图，设计相关零部件结构，最后介绍了装配工艺要求。 关键词：模具制造；复合模；装配；AutoCAD Abstract The co
