罩壳拉深工艺与级进模设计和实现 机械制造专业

罩壳拉深工艺与级进模设计摘要摘要：本文分析计算机背面板上的工艺特点，包括使用 CAD 软件的用于工件发展图中，工件的过程分析，冲裁力的计算，模具设计的难度的尺寸计算，并布局平面图和进模的模具。整体结构。进模有 8 个站，例如冲裁，空位和弯曲。设计和部件，如冲头，冲模，固定板，卸载装置，然后按选择的制造进行详细说明。与此同时，该模具的工作过程中，每个成形动作的协调，并且在冲头的装配间隙和所述模具镶块进行说明。关键词 ： 级进模 ；工艺分析；模具设计；冲裁；弯曲AbstractAbstract ： The structural characteristic of a filter mask was analyzed , and the forming technology program of the filter mask was determined. The design of layout in single-row and with few scraps was stated in detail and the total structure and characteristic of multi-position progressive die for filter mask were introduced. The strip materials were precisely oriented by side edge and pilot pin. A rapid and efficient blanking effect was achieved and the quality requirements were met.Keywords : multi-position ;progressive die ;layout; die structure; technical ;analysis目录前言................................................................1绪论 ‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥ 2第一章 工艺设计....................................................51.1 零件介绍....................................................51.2 零件工艺性分析..............................................51.3 工艺方案的确定..............................................6第二章 排样设计....................................................72.1 毛坯排样设计................................................72.2 冲切刃口外形设计............................................92.3 工序排样...................................................10第三章 工艺计算...................................................123.1 拉伸工艺力的计算...........................................12 3.1.1 冲裁力计算.......................................
