In traditional industrial production,the worker work hard ,and there are too much works,so the efficiency is low.With the development of the science and technology nowdays,the use of punching die in the industial production gain more attention,and be used in the industrail production more and more.Self-acting feed technology of punching die is also used in production,punching die could increase the efficience of production and could alleviate the work burden,so it has signification meaning in technologic progress and economic value. The article mainly discussed the classification,feature and the developmental direction of the punching technology. Elaborated the punching comonents formation principle, the basic dies structure and the rate process and the principle of design; and designed some conventional punching die : the die for big diameter three direction pipe which solved the problem of traditional maching, the darwing and punching compound die with float punch-matrix, the drawing and cutting compound dies with unaltered press, the compound die for the back bowl of the noise keeper, the design of the compound die which could produce two workpieces in one punching, the bending die for ring shape part , the bending die which used the gemel, automate loading die for cutting, the drawing, punching and burring compound die with sliding automated loading, the punching die for the long pipe with two row of hole, the drawing die for the square box shape workpiece and the burring die for the box shape workpiece . KeyWord： punching, die, die design, punching, bending, drawing 目錄 摘要 1 Abstract 2 目錄 3 第1章 緒論 5 1.1 模具選材的意義 5 1.2 模具選材的原則 6 1.3 冷沖壓模具的選材原則 8 第2章 零件的分析 10 2.1 零件的工藝性分析 10 2.2 工藝方案比較及確定 10 2.3 沖壓工藝與模具設(shè)計的內(nèi)容及步驟 11 2.4 零件及其沖壓工藝性分析 12 2.5 搭邊 12 2.6 送料進(jìn)距 12 2.7 條料寬度 13 2.8 排樣設(shè)計與計算 13 2.9 計算沖壓力與壓力中心，初選壓力機 14 2.10 計算凸、凹模刃口尺寸及公差 14 第3章 確定模具總體結(jié)構(gòu)方案 15 3.1 模具類型 15 3.2 操作與定位方式 15 3.3 卸料方式與出件方式 15 3.4 模架類型及精度 15 3.5 模具的失效形式 16 3.6 提高模具壽命的途徑 17 3.7 零件的技術(shù)要求 19 3.8 裝配技術(shù)要求 20 3.9 模具安裝要求 21 3.10 沖裁模具的試沖 21 結(jié)論與展望 25 致謝 27 參考文獻(xiàn) 28
