带有双边侧直壁几形件感温片的感温片冲压成形工艺与模具设计【弯曲模】 摘要 本设计题目为感温片冲压成形工艺与模具设计，体现了板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具设计的基础知识，为设计更复杂的冲压模具做好了铺垫并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，首先分析了工件的成形工艺及模具成形结构对制件质量的影响。介绍了感温片冲压模具设计时要注意的要点，通过对制件进行工艺分析，可确定制件的成形加工为两次工艺成形，即冲裁落料和一次弯曲。从控制制件尺寸精度出发，对感温片冲压模具的各主要尺寸进行了理论计算，以确定各工作零件的尺寸，从模具设计到零部件的加工工艺以及装配工艺等进行详细的阐述，并应用CAD进行各重要零件的设计。 关键词：冲裁落料；工艺分析；模具零部件的加工工艺。 Be
