汽车内饰件的成形工艺具设计说明书.doc

摘 要 本文主要分析了汽车内饰件的成形工艺，介绍了弯曲，冲孔，落料级进模的排样设计和模具结构设计。经工艺分析，工艺计算，确定了该设计工艺流程及冲模结构形式。模具可实现自动送料，卸料，出料，工艺性能好，冲件质量高。模具用UG，CATIA，CAD绘制出装配图和零件图。 设计过程中首先要对零件进行工艺分析，经过工艺分析和对比，确定合适的工艺方案，完成料带的排样设计；接着对冲裁力，拉深力和弯曲力进行计算，确定零件生产过程中的总冲压力，完成压力机的选择；最后对模具各零部件进行详细设计，完成模具的装配和检验。 关键词:内饰件；弯曲；冲裁；级进模 Abstract This article has mainly analyzed the car interior parts forming process,and introduces the bending ,punching,progressive die and mould structure design pat.After analysis of the technical and the process calculation , determined the design prosess and die srtucture .Mould can realize automatic feeding and unloading,discharging working performance is good ,stemping have high quality. Use UG,CATIA,CAD drawing out the assembly parts. In the proceduce of design, at first we analysis the parts, then determine the appropriate technology solutions to complete the layout design of the strip by analyzing and comparing the every process; then the blanking force, drawing force and bending forces are calculated to determine the total impulse pressure in the parts production process, then complete the press of choice; after that complet the parts of the detailed of the mold and assembly and testing of the mold. Key words: bending；punching；progressive die ……………………………………………………………………………….1 1 绪论 1.1 多工位级进模简介.........................................................................................6 1.2 冲压模具分类.................................................................................................7 1.3 冲压模具在国民经济中的地位.....................................................................8 2 零件分析及工艺方案确定 2.1 确定零件的基本冲压工序............................................................................11 2.2 工艺方案的确定............................................................................................13 2.3 零件的排样设计............................................................................................13 2.4 排样方法................................................................
