1、冷冲模课程设计说明书xxxx号件的工艺分析与模具设计院系航空宇航工程学部专业飞行器制造工程（钣金与模具）班号学号00姓名xxxxx指导教师xxxxx沈阳航空航天大学xxxx年xx月xx日沈阳航空航天大学课程设计说明书摘要摘要本次冷冲模课程设计的内容为带底孔的宽凸缘筒形件工艺分析与模具设计，分析了拉深冲孔件的结构工艺性，提出了合理的成形工艺。确定合理的冲压工艺方案，零件冲压成形的方向和模具结构，并进行了工艺参数的计算，且对模具的设计、工作过程、装配、调试工艺作了阐述。该次设计需要多种模具来完成此工件的加工。该工艺特点是首先进行落料拉深，然后拉深冲孔

2、，最后修边。采用这种方法加工的工件外观乎整、无毛刺、产品质量较高，而且大大提高了生产效率。在设计过程充分利用了各种可以利用的方式，查阅相关资料和有关手册，手工绘制装配图和相关的零件图，同时在反复的思考中不断深化对各种理论知识的理解。关键词：落料.拉深、冲孔、修边、模具结构、工艺沈阳航空航天大学课程设计说明书目录目录第1章概论····························11.1冲压设计概论························11.2冲压设计的基本内容·····················11.3冲压设计的一般工作程序··
