五(wu)(wu)(wu)金(jin)沖(chong)壓(ya)(ya)(ya)主要(yao)(yao)(yao)是按(an)工(gong)(gong)藝(yi)分(fen)類(lei)，可分(fen)為分(fen)離(li)(li)(li)工(gong)(gong)序和成(cheng)形(xing)工(gong)(gong)序兩大(da)類(lei)。分(fen)離(li)(li)(li)工(gong)(gong)序也稱沖(chong)裁，其目的(de)(de)是使五(wu)(wu)(wu)金(jin)沖(chong)壓(ya)(ya)(ya)件(jian)沿一(yi)定輪廓(kuo)線從板料上分(fen)離(li)(li)(li)，同時(shi)保證(zheng)分(fen)離(li)(li)(li)斷面的(de)(de)質量要(yao)(yao)(yao)求。成(cheng)形(xing)工(gong)(gong)序的(de)(de)目的(de)(de)是使板料在不(bu)破坯的(de)(de)條件(jian)下發生(sheng)塑性變形(xing)，制成(cheng)所需形(xing)狀(zhuang)和尺(chi)寸的(de)(de)工(gong)(gong)件(jian)。在實(shi)際生(sheng)產中，常(chang)常(chang)是多種工(gong)(gong)序綜合應用于一(yi)個工(gong)(gong)件(jian)。沖(chong)裁、彎曲、剪切、拉深、脹形(xing)、旋(xuan)壓(ya)(ya)(ya)、矯正是幾(ji)種主要(yao)(yao)(yao)的(de)(de)五(wu)(wu)(wu)金(jin)沖(chong)壓(ya)(ya)(ya)工(gong)(gong)藝(yi)。東(dong)莞市金(jin)瑞五(wu)(wu)(wu)金(jin)股份有(you)限公(gong)司-五(wu)(wu)(wu)金(jin)沖(chong)壓(ya)(ya)(ya)件(jian)、東(dong)莞五(wu)(wu)(wu)金(jin)沖(chong)壓(ya)(ya)(ya)件(jian)、五(wu)(wu)(wu)金(jin)沖(chong)壓(ya)(ya)(ya)件(jian)廠家給大(da)家分(fen)析(xi)一(yi)下：

五金(jin)(jin)沖(chong)壓(ya)用(yong)板料的表(biao)面(mian)和內在性能對五金(jin)(jin)沖(chong)壓(ya)成品(pin)的質(zhi)量影響(xiang)很(hen)大，要求五金(jin)(jin)沖(chong)壓(ya)材(cai)料厚度(du)精確、均勻；表(biao)面(mian)光潔(jie)，無斑、無疤(ba)、無擦(ca)傷、無表(biao)面(mian)裂紋等；屈(qu)服強(qiang)度(du)均勻，無明顯方向(xiang)性；均勻延伸率高；屈(qu)強(qiang)比低(di)；加工硬化(hua)性低(di)。

在實際生產中，常用與五金沖(chong)壓過程近(jin)似(si)的工(gong)藝性試(shi)驗(yan)(yan)，如拉深(shen)性能試(shi)驗(yan)(yan)、脹形性能試(shi)驗(yan)(yan)等(deng)檢(jian)驗(yan)(yan)材(cai)料的五金沖(chong)壓性能，以保證成(cheng)品質量和高(gao)的合格率。

沖(chong)壓(ya)(ya)(ya)(ya)(ya)模具的(de)精度和(he)結(jie)構(gou)直接影響五金沖(chong)壓(ya)(ya)(ya)(ya)(ya)件的(de)成(cheng)(cheng)形和(he)精度。沖(chong)壓(ya)(ya)(ya)(ya)(ya)模具制(zhi)造成(cheng)(cheng)本(ben)和(he)壽命則是影響五金沖(chong)壓(ya)(ya)(ya)(ya)(ya)件成(cheng)(cheng)本(ben)和(he)質量的(de)重要因素(su)。沖(chong)壓(ya)(ya)(ya)(ya)(ya)模具設計和(he)制(zhi)造需要較多的(de)時間，這(zhe)就延長了新五金沖(chong)壓(ya)(ya)(ya)(ya)(ya)件的(de)生(sheng)產準(zhun)備時間。

模(mo)(mo)座、模(mo)(mo)架、導向件(jian)的標準(zhun)化和發展簡易沖壓(ya)模(mo)(mo)具(供小批(pi)(pi)(pi)量生(sheng)產)、復(fu)合(he)模(mo)(mo)、多工(gong)位級(ji)進模(mo)(mo)(供大(da)量生(sheng)產)，以及研制快(kuai)速(su)換模(mo)(mo)裝置，可減少五(wu)(wu)金(jin)沖壓(ya)生(sheng)產準(zhun)備(bei)工(gong)作(zuo)量和縮(suo)短準(zhun)備(bei)時間(jian)，能使(shi)適用(yong)于(yu)減少五(wu)(wu)金(jin)沖壓(ya)生(sheng)產準(zhun)備(bei)工(gong)作(zuo)量和縮(suo)短準(zhun)備(bei)時間(jian)，能使(shi)適用(yong)于(yu)大(da)批(pi)(pi)(pi)量生(sheng)產的先進五(wu)(wu)金(jin)沖壓(ya)技(ji)術合(he)理地應用(yong)于(yu)小批(pi)(pi)(pi)量多品種生(sheng)產。
