摘 要
沖壓模具在實際工業(yè)生產(chǎn)中應(yīng)用廣泛。沖壓模具的自動送料技術(shù)也投入到實際的生產(chǎn)中，沖壓模具可以大大的提高勞動生產(chǎn)效率，減輕工人負擔(dān)，具有重要的技術(shù)進步意義和經(jīng)濟價值。在這次設(shè)計中，首先運用PRO/E軟件的三維造型功能，對零件進行三維造型。對零件進行工藝性分析，大大簡化計算并得到精確結(jié)果，在此基礎(chǔ)上應(yīng)用AutoCAD繪制零件的二維圖紙，以加深對沖裁件、拉深件和成形件結(jié)構(gòu)的工藝性的理解。設(shè)定零件的工藝方案，比較工藝方案并確定工藝方案。計算毛坯的尺寸，計算沖裁次數(shù)，設(shè)定各步半成品的尺寸并繪出工序簡圖。計算各個工序的工作壓力，設(shè)計并繪出模具簡圖，選取各個合適的零件。了解落料模、拉深模、整形模、切邊模和沖孔模的特點和需要注意的問題，在模具簡圖的基礎(chǔ)上進行模具結(jié)構(gòu)工藝性分析，進行模具結(jié)構(gòu)設(shè)計并選擇沖壓設(shè)備。

ABSTRACT
Punching die has been widely used in industry. More Self-acting feed technology of punching die is also used in production, punching die could increase the efficiencies of production and could alleviate the work burden，so it has significant meaning in technologic progress and economic value. In this design, first we use the 3D software function of PRO/E to create 3D model of the part. During the procedure, the work piece’s craftwork character is analyzed, and the work piece’s 2D drawings are made by AutoCAD, so that the work piece can be better comprehended. Learn the structural craftwork character of the work piece, so does the drawing and forming craftwork character. Make sure the work piece’s craft project, compare them and make the final decision. Calculate the size of the roughcast and select its shape. Calculate the times of the drawings, make sure the size of the semi-manufactured work piece of every steps, and draw the working procedure’s sketch. Calculate the every working pressure, design and draw die’s sketch, select every appropriate parts. Comprehend every needed dies’ character and the issues that is needed to be played more attention. On the base of the dies’ sketch ，the dies’ structure is analyzed, and then go on designing their structures and selecting punch equipments.
