沖(chong)(chong)壓(ya)(ya)加(jia)工(gong)是(shi)(shi)(shi)借助于(yu)常規(gui)或(huo)(huo)專用沖(chong)(chong)壓(ya)(ya)設備的動力，使板料在模(mo)具里直接受到變形力并(bing)進行變形，從而獲得(de)一(yi)定(ding)形狀,尺寸和(he)性(xing)能(neng)的產(chan)品零件的生產(chan)技術。沖(chong)(chong)壓(ya)(ya)自動化(hua)的板料，模(mo)具和(he)設備是(shi)(shi)(shi)沖(chong)(chong)壓(ya)(ya)加(jia)工(gong)的三要(yao)素。沖(chong)(chong)壓(ya)(ya)加(jia)工(gong)是(shi)(shi)(shi)一(yi)種金屬冷(leng)變形加(jia)工(gong)方(fang)法。所(suo)以，被稱(cheng)(cheng)之為冷(leng)沖(chong)(chong)壓(ya)(ya)或(huo)(huo)板料沖(chong)(chong)壓(ya)(ya)，簡(jian)稱(cheng)(cheng)沖(chong)(chong)壓(ya)(ya)。它是(shi)(shi)(shi)金屬塑性(xing)加(jia)工(gong)（或(huo)(huo)壓(ya)(ya)力加(jia)工(gong)）的主要(yao)方(fang)法之一(yi)，也隸(li)屬于(yu)材料成型工(gong)程技術。

　　沖(chong)(chong)壓(ya)設備廠家介(jie)紹，沖(chong)(chong)壓(ya)所(suo)使用的(de)模(mo)具(ju)(ju)稱(cheng)為沖(chong)(chong)壓(ya)模(mo)具(ju)(ju)，簡稱(cheng)沖(chong)(chong)模(mo)。沖(chong)(chong)模(mo)是(shi)將材料（金(jin)屬或非金(jin)屬）批(pi)量(liang)加工(gong)成所(suo)需(xu)沖(chong)(chong)件的(de)專用工(gong)具(ju)(ju)。沖(chong)(chong)模(mo)在沖(chong)(chong)壓(ya)中至關重要(yao)(yao)，沒有符(fu)合要(yao)(yao)求的(de)沖(chong)(chong)模(mo)，批(pi)量(liang)沖(chong)(chong)壓(ya)生產就難以進行；沒有先進的(de)沖(chong)(chong)模(mo)，先進的(de)沖(chong)(chong)壓(ya)工(gong)藝就無法(fa)實(shi)現。

　　沖(chong)壓(ya)工藝(yi)與模(mo)具、沖(chong)壓(ya)設備和沖(chong)壓(ya)材料構成沖(chong)壓(ya)加工的(de)三要素，沖(chong)壓(ya)自動化公司分析(xi)，只有它們相互結(jie)合才能(neng)得(de)出(chu)沖(chong)壓(ya)件。

那種很長一(yi)(yi)條(tiao)(tiao)條(tiao)(tiao)的還(huan)是(shi)冷沖(chong)壓，只是(shi)沖(chong)壓模(mo)(mo)具(ju)不同(tong)，一(yi)(yi)條(tiao)(tiao)料(liao)帶(dai)連續(xu)送料(liao)的就叫連續(xu)模(mo)(mo)，把單(dan)個(ge)(ge)產品再放進(jin)去(qu)加工(gong)的，叫單(dan)沖(chong)模(mo)(mo)，把料(liao)帶(dai)一(yi)(yi)個(ge)(ge)個(ge)(ge)放進(jin)去(qu)沖(chong)的，叫復(fu)合模(mo)(mo)
