设计简介
摘 要
模具是制造业的重要工艺基础，在我国，模具制造属于专用设备制造业。中国虽然很早就开始制造模具和使用模具，但长期未形成产业。直到20世纪80年代后期，中国模具工业才驶入发展的快车道。近年，不仅国有模具企业有了很大发展，三资企业、乡镇模具企业的发展也相当迅速。冷冲压模具在现代工业中具有很重要的作用，其在机械制造、电子、电器 等各行各业中都有广泛的应用。用冷冲压加工方法可以得到形状复杂、用其它加工方法难以加工的工件，如薄壳零件等。冷冲压的尺寸精度是由模具保证的，因此，尺寸稳定，互换性好。
多工位级进模是在普通级进模的基础上发展起来的精密、高效、高寿命的先进模具。多工位级进模在不同的工位可以连续完成复杂零件的冲裁、弯曲、拉深、翻孔、翻边及其它成形等工序。主要用于生产批量大、材料厚度较薄、形状复杂、精度要求较高的中小型冲压件的生产。本文结合盖子零件的结构、工艺性来分析设计盖子模具结构、工艺性及工作原理，进行必要的计算，确定基本的参数、设计主体结构、排样图、工作零件、卸料装置、导料装置、安全装置、画装配图、零件图、编制模具零件加工工艺规程等。
本设计是盖子零件冲裁模具的设计，掌握模具工艺设计和模具结构设计的方法和步骤，掌握制造加工工艺的编制技术，进行盖子的设计，学习应用先进的方法，完成此课题的设计。
