汽車前燈罩的沖壓模具設計
學生姓名：聶文軍 班級：0781053
指導老師：陳為國
摘要: 本文介紹了汽車前燈罩的沖壓模具設計。設計內(nèi)容包括產(chǎn)品零件工藝分析、模具設計以及主要零件制造工藝的確定等。
此零件結構復雜，需要多道工序完成，基本工序包括落料、拉深、沖孔、彎曲、翻邊等。針對此產(chǎn)品件，應明確設計路線，確定設計方案，構思模具結構。首先對產(chǎn)品進行結構和尺寸分析，利用AUTOCAD繪出零件的三向視圖，確定尺寸；之后確定優(yōu)選的工藝方案（落料、拉深—脹形、沖孔—脹形、沖孔—修邊、沖孔—彎曲—沖孔、翻邊）；然后再進行必要的工藝計算和尺寸計算，利用AUTOCAD完成第一道工序—落料拉深復合模裝配圖，并繪出各非標零件；然后同樣用AUTOCAD完成第二道工序—脹形沖孔復合模；對其它工序進行分析，確定每道工序的細節(jié)工作；最后完成設計。

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.
