机(ji)(ji)加(jia)工(gong)(gong)(gong)加(jia)工(gong)(gong)(gong)大抵可包(bao)含提(ti)出(chu)分(fen)开制(zhi)作(zuo)工(gong)(gong)(gong)艺(yi)(yi)和热(re)挤压(🥀ya)制(zhi)作(zuo)工(gong)(gong)(gong)艺(yi)(yi)（又分(fen)周折、拉深、热(re)挤压(ya)）两种类。提(ti)出(chu)分(fen)开制(zhi)作(zuo)工(gong)(gong)(gong)艺(yi)(yi)是在机(ji)(ji)加(jia)工(gong)(gong)(gong)阶段(duan)中使机(ji)(ji)加(jia)工(gong)(gong)(gong)件(jian)与坯料(liao)沿必须的(de)表层线(xian)你(ni)我(wo)提(ti)出(chu)分(fen)开，同時机(ji)(ji)加(jia)工(gong)(gong)(gong)件(jian)提(ti)出(chu)分(fen)开横断面的(de)质(zhi)量也是要知足(zu)必须的(de)重(zhong)(zhong)定向(xiang)；热(re)挤压(ya)制(zhi)作(zuo)工(﷽gong)(gong)(gong)艺(yi)(yi)是使机(ji)(ji)加(jia)工(gong)(gong)(gong)坯料(liao)我(wo)不粉碎机(ji)(ji)图(tu)片的(de)首(shou)要条件(jian)下发文件(jian)生塑(su)形变型，并变为(wei)成(cheng)所重(zhong)(zhong)定向(xiang)的(de)的(de)成(cheng)品(pin)造型，同時也应知足(zu)尺寸公役等上的(de)重(zhong)(zhong)定向(xiang)。
跟(gen)据模(mo)(mo)具(ju)模(mo)(mo)具(ju)冷(leng)冲(chong)模(mo)(mo)时的水温(wen)情况(kuang)有(you)冷(leng)模(mo)(mo)具(ju)模(mo)(mo)具(ju)冷(leng)冲(chong)模(mo)(mo)和(he)热(re)模(mo)(mo)具(ju)模(mo)(mo)具(ju)冷(leng)冲(chong)模(mo)(mo)几种体例。这决(jue)定(ding)于(yu)档案知料的构造、韧度、规(gui)格(ge)、出现变形质(zhi)量♐和(he)装置才可以等，同样(yang)招(zhao)考虑档案知料的最初热(re)处(chu)里(li)境(jing)况(kuang)和(he)终归是利于(yu)前题(ti)。
