用于制造(zao)毛胚、機(ji)械(xie)零件(jian)(jian)(jian)的塑性加(jia)工(gong)方(fang)法(fa)，可(ke)以增加(jia)胚料的外力(li)，使其(qi)產生形狀(zhuang)變(bian)化，改變(bian)規格、形狀(zhuang)和特性。是煅造(zao)與沖壓加(jia)工(gong)總稱。鍛造(zao)件(jian)(jian)(jian)的制造(zao)商介(jie)紹了鍛造(zao)件(jian)(jian)(jian)的概(gai)念(nian)。
鍛(duan)(duan)壓件是鑄造和沖(chong)壓加(jia)工的統稱，是運(yun)用(yong)鍛(duan)(duan)壓件機械鉆頭(tou)、砧(zhen)塊(kuai)、沖(chong)針或者通過磨具(ju)對(dui)胚料施壓，使(shi)其造成形狀變化，從而(er)得到需要形狀和尺寸的制(zhi)作(zuo)的塑性加(jia)工方式。
鍛(duan)(duan)件(jian)(jian)(jian)類型：鍛(duan)(duan)件(jian)(jian)(jian)按成型方法和變形(xing)(xing)溫(wen)(wen)度(du)進(jin)行篩選(xuan)。根據成型方法，鍛(duan)(duan)造(zao)(zao)件(jian)(jian)(jian)可分為鍛(duan)(duan)造(zao)(zao)件(jian)(jian)(jian)和沖(chong)壓件(jian)(jian)(jian)；根據變形(xing)(xing)溫(wen)(wen)度(du)，鍛(duan)(duan)造(zao)(zao)件(jian)(jian)(jian)可分為熱鍛(duan)(duan)件(jian)(jian)(jian)、冷鍛(duan)(duan)件(jian)(jian)(jian)、溫(wen)(wen)鍛(duan)(duan)件(jian)(jian)(jian)和等溫(wen)(wen)過程鍛(duan)(duan)造(zao)(zao)件(jian)(jian)(jian)。
