摘 要
沖壓模具成型技術(shù)是屬于少切削或無切削的加工方法，沖壓成型的生產(chǎn)效率比較高，沖壓件的質(zhì)量好，其產(chǎn)品的一致性好、應(yīng)用范圍廣泛等特點已經(jīng)得到了越來越多的企業(yè)的認(rèn)可。沖壓工藝廣泛應(yīng)用于汽車、電器、儀器儀表、航天航空以及各種民用輕工業(yè)的行業(yè)，是如今工業(yè)上生產(chǎn)的重要工藝方法和研究方向。
本套模具設(shè)計的是我們?nèi)粘Ｉ钪休^為常見的罩圈，涉及的工藝方法都是沖壓模具中應(yīng)用比較廣泛的工序，其包括落料、拉深、沖孔、翻邊等工序。我所設(shè)計的模具是采用復(fù)合模在一次成型過程中完成落料、拉深、沖孔、翻邊這四個過程，在設(shè)計的過程中我首選分析了沖壓件的工藝性能，再選擇工藝方案，接下來進行一系列的有關(guān)工藝參數(shù)計算，再選擇合適的沖壓設(shè)備，再對模具的總體結(jié)構(gòu)進行設(shè)計，最后完成整套模具設(shè)計。
通過這一次的畢業(yè)設(shè)計，讓我對所學(xué)的沖壓模具課程有了進一步的了解，也掌握了很多的沖壓模具設(shè)計上的技術(shù)，比如查閱資料設(shè)計和計算、采用輔助軟件PRO/E三維建模和CAD制圖，很好的完成了一次理論結(jié)合實際的綜合知識應(yīng)用，對我以后的工作有了很大的提升。

ABSTRACT
Stamping die molding technology is a small cutting or no cutting of the processing methods, stamping production efficiency is relatively high, stamping parts of good quality, and its products consistent, wide range of applications and other characteristics have been more and more enterprises The approval. Stamping process is widely used in automobiles, electrical appliances, instrumentation, aerospace and a variety of civilian light industry industry, is now an important industrial production methods and research direction.
This set of mold design is our daily life more common hood, involving the process are stamping die application in a wide range of processes, including blanking, drawing, punching, flanging and other processes. I designed the mold is the use of composite mold in a molding process to complete the blanking, drawing, punching, flanging these four processes, in the design process I preferred to analyze the stamping parts of the process performance, and then select the process , Followed by a series of calculation of the process parameters, and then select the appropriate stamping equipment, and then the overall structure of the mold design, and finally complete the entire mold design.
Through this graduation design, let me learn the stamping die course has a better understanding, but also mastered a lot of stamping die design technology, such as access to information design and calculation, the use of auxiliary software PRO / E three-dimensional modeling And CAD mapping, a good completion of a theory combined with the actual application of the comprehensive knowledge of my future work has been greatly improved.
Keywords: stamping die, mold design, composite mold, hood ring.
