a.沖(chong)(chong)剪模(mo)具:是以剪切(qie)作用完成工作的(de)(de),常用的(de)(de)形式有剪斷沖(chong)(chong)模(mo)、下料(liao)沖(chong)(chong)模(mo)、沖(chong)(chong)孔沖(chong)(chong)模(mo)、修邊(bian)沖(chong)(chong)模(mo)、整(zheng)緣沖(chong)(chong)模(mo)、拉孔沖(chong)(chong)模(mo)和(he)沖(chong)(chong)切(qie)模(mo)具。
b.彎(wan)曲模具:是將平整(zheng)的(de)毛胚彎(wan)成一個角度(du)的(de)形狀,視零(ling)件的(de)形狀、精(jing)度(du)及生產量的(de)多寡,乃有多種不同形式的(de)模具,如普(pu)通彎(wan)曲沖(chong)模、凸輪彎(wan)曲沖(chong)模、卷邊沖(chong)模、圓弧彎(wan)曲沖(chong)模、折彎(wan)沖(chong)縫沖(chong)模與(yu)扭曲沖(chong)模等。
c.抽制(zhi)(zhi)模具:抽制(zhi)(zhi)模具是將平面毛胚(pei)制(zhi)(zhi)成(cheng)有底無縫容器。
d.成形(xing)(xing)模(mo)(mo)(mo)具:指用各種局部變(bian)(bian)形(xing)(xing)的方(fang)法來改變(bian)(bian)毛胚的形(xing)(xing)狀,其形(xing)(xing)式有凸張成形(xing)(xing)沖模(mo)(mo)(mo)、卷緣成形(xing)(xing)沖模(mo)(mo)(mo)、頸縮成形(xing)(xing)沖模(mo)(mo)(mo)、孔凸緣成形(xing)(xing)沖模(mo)(mo)(mo)、圓緣成形(xing)(xing)沖模(mo)(mo)(mo)。
