1、沖壓模具在實際工業(yè)牛產(chǎn)中應(yīng)用廣泛。在傳統(tǒng)的工業(yè)生產(chǎn)中，工人牛產(chǎn)的勞動強度大、勞動量大，嚴重影響生產(chǎn)效率的提高。隨著當今科技的發(fā)展，工業(yè)生產(chǎn)中的模具的使用已經(jīng)越來越引起人們的重視，而被大量應(yīng)用到工業(yè)生產(chǎn)中來。沖壓模具的自動送料技術(shù)也投入到實際生產(chǎn)屮，沖壓模具可以大大的提高勞動成產(chǎn)率，減輕工人的負擔，具有重要的技術(shù)進步意義和經(jīng)濟價值。木文對冷沖壓技術(shù)的分類、特點及發(fā)展方向作了簡略的概述：論述了沖壓零件的成形原理、基本模具結(jié)構(gòu)與運動過程及其設(shè)計原理；對典型的沖壓件零件進行了設(shè)計：此設(shè)計解決了沖壓模具的加工難題，沖壓模具的設(shè)計充
2、分利用了機械壓力機的功用特點，在室溫的條件下對坯件進行沖壓成形，生產(chǎn)效率高，經(jīng)濟效益顯著。關(guān)鍵詞沖壓、模具、模具設(shè)計、工藝凹模外文畫譯上固走板上?？胀鼓Ｏ聣|板設(shè)計說明書摘要目錄說明書匯總圖紙下圉走板模具裝配圏下模些板AbstractPunchingdiehasbeenwidelyusedintheactualindustrialproduction.Intraditionalindustrialproduction,theworkerworkhard,andtherearetoomuchworks,sotheeffici
