摘要
以無凸緣圓筒形工件為例，結(jié)合其模具設(shè)計特有工藝性，進行了工藝性分析，并分析了成形過程的三種不同的沖壓工藝方案，從理論探討及實驗上提出了最佳工藝方案。介紹了模具設(shè)計要點。介紹了沖壓工藝分解過程、排樣圖、模具結(jié)構(gòu)分析、工作原理；并對模具的各部分主要尺寸進行理論運算，以確定各沖模的尺寸；對落料—拉深模具從設(shè)計到零部件的加工工藝以及裝配工藝等進行了詳細(xì)闡述，簡要分析了模具關(guān)鍵零部件的設(shè)計及加工工藝。實踐證明，模具結(jié)構(gòu)能很好地滿足零件的精度要求，不僅模具結(jié)構(gòu)左右對稱，受力均勻，而且生產(chǎn)效率高。

Abstract
Taking type or paste here to translate text as an instans,combining with its special of die design,the process analysis ,and three kinds of different stamping technique plans were analyzed, optimal processing plan and feasible forming die were obtained according to theoretical analysis and experiment. The critical points of die design are introduced.The decomposing process of punching,layout,die structure analysis are carried out,woek principle;and the theoretical calculation to the main dimensions of die are carried out so as to determine the size of different punching dies; the die design and the process of parts as well as the assembling process and blanking-drawing compound die are stated in details,the design and manufacture process of the key part of the die were also discussed in brief. Practical application showed,that the die structure could meet the require meet the spare parts accuracy ,not only are the die structure and force condition symmetrical,but also the production efficiency is hign.
