不锈钢盖冲裁模具设计-拉伸膜 摘要 本设计主要对不锈钢盖进行冲裁模具设计。结合公司实际生产要求和产品的特点，在厂原有的设计上，对模具进行了改进设计。本设计对拉深件加工工艺进行了分析，得出了最佳加工方案，在充分保证零件质量与精度的前提下，选择高生产率的加工工艺，降低生产成本，从而有效地节约了材料。本设计中使用计算机软件进行了辅助设计，在保证高精度的同时简化了传统的繁琐计算过程，使设计更为便捷。 本次设计是在指导老师认真、耐心的指导下，对模具的经济性、模具的寿命、生产周期、及生产成本等指标下进行全面、仔细的分析下而进行设计的。在此,我表示衷心的感谢他们对我的教诲. 冲模是模具设计与制造专业的主要专业课程之一。它具有很强的实践性和综合性，通过学习这门课程，使我对冲压模具有了新的认识，从中也学到了不少知识，激发了我对冲压模具的爱好。 但因本人经验有限，因此很难避免的存在一些不合理之处，望各位老师批评和指正，以使我的设计做到合理，同时也为我走出校门步入社会打下坚实的基矗 关键词：不锈钢盖；冲裁模具；加工工艺；模具设计 Abstract This desig
