In the traditional industrial production, the worker work very hard, and there are too much work, so the efficiency is low. With the development of the science and technology nowadays, the use of punching die in the industial production gain more attention, and be used in the industrial 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 significant meaning in technologic progress and economic value.This Article proposes using mold to produce retainer of the new technology, And against a standard fixture retainer design of the compound dies. The main problems of this mold design is how to solve retainer of punching holes, determine mold structure, how to manufacturing the mold and selected blanking programs and so on. This Article Combine the characteristics of retainer, concretely solve the choice and verify check of the press machine, the numeration and structure design of the point dimension of punch and matrix, the locating project design, the method of stripper, the main mold parts processing, the choice of standard parts, the design of the model assemble. These designs can provide realistic guiding significance for similar mold design. But the characteristics of the design is to try to using the complicate dies. To solve the problem of original process, such as large numbers of die, long process of technology, high production cost, low efficiency, difficulty in keeping symmetry of working parts are solved, and a reliable evidence for the workout of stamping process and die design of these parts is provided.The dies here discussed can be easily made, conveniently used, and safely operated. And it could be used as the reference in the large scale production of similar workpieces.key words: dies; compound dies; blanking force; blanking dearanceSignature of supervisor:目錄1 緒論 .11.1 模具行業(yè) .11.2 國內(nèi)外模具發(fā)展?fàn)顩r及趨勢 .11.3 本次設(shè)計的主要方向、內(nèi)容及目的 .22 沖裁件的工藝分析 .32.1 沖裁件的材料及結(jié)構(gòu)的工藝性 .32.2 批量生產(chǎn) .32.3 沖壓件工藝分析 .42.4 沖裁件工藝設(shè)計 .43 沖壓設(shè)計 .43.1 計算搭邊值 .43.2 條料寬度 .43. 3 排樣圖 .53.4 沖裁力的計算 .53.6 壓力機噸位的選用 .64 沖裁模具相關(guān)參數(shù)計算 .64.1 計算 .64.2 經(jīng)驗確定一些經(jīng)驗 .65 沖裁模刃口的計算 .75.1 確定模具磨損系數(shù) .75.2 凸凹模的加工 .76 其余模具標(biāo)準(zhǔn)零件 .86.1 固定擋料銷及導(dǎo)料銷 .86.2 推桿 .96.3 防轉(zhuǎn)銷 .96.4 圓柱銷 106.5 卸料螺釘 116.6 內(nèi)六角圓柱頭螺釘 116.7 模柄 126.8 卸料彈簧 136.9 導(dǎo)柱導(dǎo)套 146.10 模座 147 模具裝配與調(diào)試 .157.1 模具裝配特點 157.2 裝配技術(shù)要求 157.3 裝配過程 167.3.1 常用的裝模工具 .167.3.2 模具的裝配 .167.4 裝模與試模 177.4.1 模具的安裝 177.5 檢驗和驗收技術(shù)條件 207.6 使用規(guī)定 207.7 沖模設(shè)計的審核項目 21結(jié)論 24參 考 文 獻 .25致謝 26
