支撑盘的冲压成形工艺及模具设计【带凸缘锥形件拉深冲孔落料复合模】 摘要:该设计题目为支撑盘冲压成形工艺及模具设计，体现了盘类冲压零件的设计要求、内容及方向。有一定的设计意义，通过对该零件模具的设计，进一步加强了设计者冲压模设计的基础知识，为设计更复杂的冲压模具做好铺垫和吸取了更深刻的经验。 本设计运用冲压成型工艺及模具设计的基础知识，首先对零件进行工艺性分析，以确定冲压工序，然后计算零件的体积，便于选取合适的压力机，最后分析了零件的特征，确定模具的设计参数、设计要点及卸料装置的选龋 本冲压件的外缘和内孔均为圆形，所以在设计模具结构时，应考虑内孔与外缘的相对位置精度。又由于零件需要拉深，所以复合模是首选，其工序即为：冲孔、落料、拉深。模具的设计中，设计凹模是关键，结合本副模具及零件的特点，刚性推件装置是比较合适的选择。 关键词：冲压模复合模凹模 Disk die desig
