汽车前灯罩的冲压模具设计 学生姓名： 班级： 指导老师：摘要: 本文介绍了汽车前灯罩的冲压模具设计。设计内容包括产品零件工艺分析、模具设计以及主要零件制造工艺的确定等。此零件结构复杂，需要多道工序完成，基本工序包括落料、拉深、冲孔、弯曲、翻边等。针对此产品件，应明确设计路线，确定设计方案，构思模具结构。首先对产品进行结构和尺寸分析，利用AUTOCAD绘出零件的三向视图，确定尺寸；之后确定优选的工艺方案（落料、拉深胀形、冲孔胀形、冲孔修边、冲孔弯曲冲孔、翻边）；然后再进行必要的工艺计算和尺寸计算，利用AUTOCAD完成第一道工序落料拉深复合模装配图，并绘出各非标零件；然后同样用AUTOCAD完成第二道工序胀形冲孔复合模；对其它工序进行分析，确定每道工序的细节工作；最后完成设计。关键词：灯罩 冲压 模具 工艺 设计指导老师签名：Automotive Stamping Die Design front lamp shades Student name: Class: Supervisor: Abstract: This paper describes the car before the shade of the stamping die design. Includes part of the product design process analysis, mold design and manufacturing process to determine the main parts and so on. This part is complex, requires multiple procedures done, the basic processes include blanking, drawing, punching, bending, flanging and so on. Parts for this product, the design should be clear lines to determine the design, the idea of the mold structure. First, the product structure and size analysis, the use of AUTOCAD to draw part of the three views to determine the size; then determine the optimal process plan (Blanking, Drawing - bulging, punching - bulging, punching - trimming, Punching - Bending - piercing and flanging); and then make the necessary calculation and dimensioning techniques, the use of AUTOCAD to complete the first process - drawing composite blanking die assembly drawing, and draw the non-standard part; then the same with AUTOCAD completion of the second procedure - bulging punching compound die; of other processes were analyzed to determine the details of each process of work; the last to complete the design.Keyw
