1、摘 要冲压模具是实现冲压工艺的主要工艺装备，它直接影响到机电产品的质量、生产成本、更新周期及市场竞争能力。在国民经济中的重要地位，已越来越受到重视。此课题主要对加工长孔圆垫片的冲压级进模进行设计，借助AutoCAD根据零件图的技术要求进行二维零件、装配图绘制，通过UG进行三维实体建模、实体装配以及生成爆炸图。长孔圆垫片的加工分为冲孔和落料两道工序。根据零件的尺寸、材料、批量生产等要求，主要设计内容为长孔圆垫片的冲裁工艺性分析；工件的排样与搭边计算；冲压力及冲压中心的计算；模具主要零件的结构设计；对部件进行标准化的选用；对模具及主要零部件进行了详细的绘图。目前，模具零件大多已经标准化，设计时选用
2、标准件，如模架，导柱、导套、上下模座等给设计带来很大的便利。重点是对凸模和凹模工作部分尺寸的计算，结构尺寸的设计。最后选择合适的压力机，保证必要的冲压力和合适的模具闭合高度。明确了设计思路，确定了冲压成型工艺过程，巩固和深化了所学知识。整个设计过程中结合所学专业知识，同时查阅了大量文献资料，最终完成本次毕业设计。关键词: 冲压工艺；级进模；设计AbstractStamping die stamping process technology and equipment, it directly affects the quality of the mechanical and electrica
