沖(chong)(chong)壓(ya)是靠壓(ya)力(li)機(ji)和(he)(he)(he)模具對板(ban)材(cai)(cai)、帶材(cai)(cai)、管材(cai)(cai)和(he)(he)(he)型材(cai)(cai)等(deng)施加(jia)外力(li)，使之(zhi)產(chan)生塑性(xing)變(bian)(bian)形(xing)或(huo)分離，從(cong)而獲(huo)得所需形(xing)狀和(he)(he)(he)尺寸(cun)的(de)(de)工(gong)件(jian)（沖(chong)(chong)壓(ya)件(jian)）的(de)(de)成形(xing)加(jia)工(gong)方法。沖(chong)(chong)壓(ya)和(he)(he)(he)鍛造同屬(shu)塑性(xing)加(jia)工(gong)（或(huo)稱壓(ya)力(li)加(jia)工(gong)），合(he)稱鍛壓(ya)。沖(chong)(chong)壓(ya)的(de)(de)坯料主要(yao)是熱(re)(re)軋(ya)和(he)(he)(he)冷(leng)軋(ya)的(de)(de)鋼板(ban)和(he)(he)(he)鋼帶。全世界的(de)(de)鋼材(cai)(cai)中(zhong)(zhong)，有60～70%是板(ban)材(cai)(cai)，其(qi)中(zhong)(zhong)大部(bu)分經過(guo)沖(chong)(chong)壓(ya)制(zhi)成成品(pin)。汽(qi)車(che)的(de)(de)車(che)身(shen)、底盤(pan)、油箱、散(san)熱(re)(re)器(qi)(qi)片(pian)，鍋爐(lu)的(de)(de)汽(qi)包，容器(qi)(qi)的(de)(de)殼(ke)體(ti)，電機(ji)、電器(qi)(qi)的(de)(de)鐵芯硅鋼片(pian)等(deng)都是沖(chong)(chong)壓(ya)加(jia)工(gong)的(de)(de)。儀(yi)器(qi)(qi)儀(yi)表、家用電器(qi)(qi)、自行車(che)、辦公機(ji)械、生活器(qi)(qi)皿等(deng)產(chan)品(pin)中(zhong)(zhong)，也有大量(liang)沖(chong)(chong)壓(ya)件(jian)。益(yi)陽金屬(shu)沖(chong)(chong)壓(ya)聯(lian)系方式平板(ban)變(bian)(bian)壓(ya)器(qi)(qi)銅(tong)片(pian)沖(chong)(chong)壓(ya)的(de)(de)過(guo)程包括銅(tong)片(pian)的(de)(de)預處理、模具的(de)(de)設計和(he)(he)(he)制(zhi)造、沖(chong)(chong)壓(ya)機(ji)的(de)(de)選擇(ze)和(he)(he)(he)操作(zuo)、以(yi)及成品(pin)的(de)(de)檢(jian)測等(deng)。

儀器(qi)儀表(biao)、家用電器(qi)、自(zi)行車、辦公機械、生(sheng)活器(qi)皿等產品中，也有大量(liang)沖壓件(jian)。沖壓加(jia)(jia)(jia)(jia)工(gong)(gong)是借助于常規(gui)或**沖壓設(she)備的(de)(de)動力(li)，使板(ban)(ban)料在模具(ju)里直(zhi)接受到變形力(li)并進(jin)行變形，從而獲(huo)得一(yi)定形狀、尺寸和(he)性(xing)能(neng)的(de)(de)產品零件(jian)的(de)(de)生(sheng)產技術(shu)。板(ban)(ban)料，模具(ju)和(he)設(she)備是沖壓加(jia)(jia)(jia)(jia)工(gong)(gong)的(de)(de)三要素(su)。按沖壓加(jia)(jia)(jia)(jia)工(gong)(gong)溫度分為(wei)熱(re)沖壓和(he)冷沖壓。前者適合變形抗力(li)高，塑(su)性(xing)較差的(de)(de)板(ban)(ban)料加(jia)(jia)(jia)(jia)工(gong)(gong)；后者則在室溫下進(jin)行，是薄板(ban)(ban)常用的(de)(de)沖壓方法。它是金屬塑(su)性(xing)加(jia)(jia)(jia)(jia)工(gong)(gong)（或壓力(li)加(jia)(jia)(jia)(jia)工(gong)(gong)）的(de)(de)主要方法之一(yi)，也隸屬于材料成型工(gong)(gong)程技術(shu)。

在每分鐘生(sheng)(sheng)(sheng)產(chan)數(shu)十、數(shu)百件沖壓(ya)(ya)件的(de)情況下，在短暫時(shi)間內完(wan)成送料、沖壓(ya)(ya)、出件、排廢料等(deng)工序，常常發(fa)生(sheng)(sheng)(sheng)人身、設(she)備和質量事故。因此，沖壓(ya)(ya)中的(de)安(an)(an)全(quan)生(sheng)(sheng)(sheng)產(chan)是一個非常重要的(de)問題(ti)。沖壓(ya)(ya)的(de)安(an)(an)全(quan)措施是：①實現機(ji)(ji)械(xie)化、自動化進(jin)出料。②設(she)置(zhi)(zhi)機(ji)(ji)械(xie)防護(hu)裝置(zhi)(zhi)，防止傷手。應(ying)用(yong)模具防護(hu)罩、自動退料裝置(zhi)(zhi)和手工工具進(jin)出料。③設(she)置(zhi)(zhi)電氣保護(hu)、斷電裝置(zhi)(zhi)。設(she)置(zhi)(zhi)光電或氣幕保護(hu)開關(guan)、雙手或多手串聯(lian)啟動開關(guan)、防誤操作裝置(zhi)(zhi)等(deng)。④改進(jin)離合器和制動結構，在危(wei)險信(xin)號發(fa)出后，壓(ya)(ya)力機(ji)(ji)的(de)曲軸(zhou)、連桿、沖頭能立(li)即(ji)停止在原位上。鐵沖壓(ya)(ya)件的(de)生(sheng)(sheng)(sheng)產(chan)成本相對較低，但是可以提(ti)高產(chan)品的(de)質量和生(sheng)(sheng)(sheng)產(chan)效率，因此被(bei)應(ying)用(yong)于各(ge)種(zhong)行業(ye)。
