1、基座片级进模设计及其制造工艺IV摘要本论文应用专业所学课程的理论和生产实际知识，进行一次冷冲压模具设计工作的实际训练从而培养和提高学生独立工作能力，巩固与扩充了冷冲压模具设计等课程所学的内容，掌握冷冲压模具设计的方法和步骤，掌握冷冲压模具设计的基本技能，懂得怎样分析零件的工艺性，怎样确定工艺方案，通过对比和结合实际生产需要，明白了单工序模、复合模、级进模各个优势所在，了解了模具的基本结构，提高了计算能力，绘图能力，熟悉了规范和标准，同时各科相关的课程都有了全面的复习，独立思考的能力也有了提高。本次设计主要是基座片级进模设计，
2、精度一般，形状较为复杂，生产批量是大批量。手工送料，材料为可伐合金。通过工艺性分析，次零件需要经过拉深，冲孔，切口，整形，翻边落料等工序完成，经计算决定采用级进模来完成加工，分别有侧刃定距，冲工艺孔，切口，空工位，拉深，对拉深的底面整形，冲孔，空工位，落料翻边这9个工序。模架选择四角导柱式，导向精度高，前后左右都可以进料。关键字：落料，拉深，级进模基座片级进模设计及其制造工艺IVABSTRACTThisthesisappliedprofessionalcurriculumtheoryandtheactualproductio
