沖剪模具：是以剪切作用完成工作的，常用的形式有剪斷沖模、下料沖模、沖孔沖模、修邊沖模、整緣沖模、拉孔沖模和沖切模具。b.彎曲模具：是將平整的毛胚彎成一個(gè)角度的形狀，視零件的形狀、精度及生產(chǎn)量的多寡，乃有多種不同形式的模具，如普通彎曲沖模、凸輪彎曲沖模、卷邊沖模、圓弧彎曲沖模、折彎沖縫沖模與扭曲沖模等。c.抽制模具：抽制模具是將平面毛胚制成有底無縫容器。d.成形模具：指用各種局部變形的方法來改變毛胚的形狀，其形式有凸張成形沖模、卷緣成形沖模、頸縮成形沖模、孔凸緣成形沖模、圓緣成形沖模。e.壓縮模具：是利用強(qiáng)大的壓力，使金屬毛胚流動(dòng)變形，成為所需的形狀，其種類有擠制沖模、壓花沖模、壓印沖模、端壓沖模。東陽(yáng)汽車沖壓模具力求孔徑規(guī)范化，降低汽車模具的制造和維修保養(yǎng)費(fèi)用。</p><div
