無論什么形狀的板料沖壓件，都要經(jīng)過沖裁工序（步）才能完成沖壓。深喉沖床生產(chǎn)廠家介紹說沖裁是沖孔和落料的總稱。即便是直接從原材料（包括板、條、帶、卷料），用多工位連續(xù)式復(fù)合模一模成形沖制完成的各類形狀復(fù)雜的立體形沖壓成形件，也必須具有落料工位。為了在沖壓時(shí)能達(dá)到要求的沖件尺寸與形位精度、沖切面質(zhì)量、模具壽命，要根據(jù)沖件材料牌號、供應(yīng)狀態(tài)（軟、硬、半硬態(tài)）、料厚以及材料的抗剪強(qiáng)度eτ來選取合理沖裁間隙。選用合理沖裁間隙分兩步走，即所謂兩步法：第1步確定選用間隙類別根據(jù)沖裁件技術(shù)要求：沖切面質(zhì)量、尺寸精度及沖模壽命等要素，從GB/T16743中所列的“沖裁間隙分類表”上選定要采用的間隙類別。第2步選取間隙比值并計(jì)算間隙值依照選用間隙類別，在該國標(biāo)給定的“沖裁間隙比值表”中查出相應(yīng)間隙類別的間隙比值，經(jīng)計(jì)算即獲合理間隙值。對于該國標(biāo)的沖裁間隙比值表中未列出的金屬材料，可參照該表中抗剪強(qiáng)度eτ相近的材料選取合理的間隙比值。由于該間隙比值表中給定的各類間隙比值都是一個(gè)數(shù)值波動(dòng)幅度相當(dāng)大的范圍，下限比值與上限比值有的竟相差一倍多。這種情況在沖裁比值表的Ⅰ類間隙中較為明顯。如低碳鋼Ⅰ類間隙比值為（）%t,中碳鋼為。</p></p><br
