汽車沖(chong)壓件制造工藝介(jie)紹

　　之(zhi)前給大家(jia)介(jie)紹了汽車沖(chong)壓(ya)(ya)件(jian)工藝開(kai)發的(de)作用(yong)，下面(mian)再來和大家(jia)探討一(yi)下沖(chong)壓(ya)(ya)件(jian)制(zhi)造工藝，希望對你(ni)有(you)所幫助。

　　汽車沖(chong)壓(ya)件制造(zao)工藝(yi)的整(zheng)(zheng)個(ge)過(guo)程涉及到很多要點，需(xu)要從幾(ji)個(ge)方面給予更多的關注，比如基本(ben)沖(chong)壓(ya)工藝(yi)的選(xuan)擇。沖(chong)壓(ya)工藝(yi)的科學選(xuan)擇可以保證制造(zao)工藝(yi)的整(zheng)(zheng)體效率。

　　普通沖(chong)壓工藝(yi)(yi)中(zhong)的(de)(de)切(qie)邊、翻邊和下料是(shi)(shi)重要的(de)(de)工藝(yi)(yi)，也具有鮮明的(de)(de)特點。從零件圖中(zhong)可(ke)以(yi)直(zhi)觀地看到一些(xie)工藝(yi)(yi)的(de)(de)性質，沖(chong)孔和剪(jian)切(qie)是(shi)(shi)常用的(de)(de)工藝(yi)(yi)。開(kai)口筒形(xing)零件可(ke)通過拉(la)深制(zhi)作，零件應結合(he)供需要求進行計算(suan)分(fen)析，確定工藝(yi)(yi)性質。在(zai)工藝(yi)(yi)選(xuan)擇過程中(zhong)，油封(feng)外夾圈(quan)和內夾圈(quan)沖(chong)壓件的(de)(de)形(xing)狀相似，僅在(zai)外徑和直(zhi)邊高度(du)上存在(zai)差異擇工藝(yi)(yi)前需要進行詳細的(de)(de)計算(suan)和分(fen)析。

　　此外(wai)，還應(ying)注意(yi)(yi)沖(chong)壓的數(shu)(shu)(shu)(shu)量(liang)和(he)順序(xu)，以確保本環節的運行質量(liang)。重復工(gong)序(xu)的數(shu)(shu)(shu)(shu)量(liang)為沖(chong)壓次數(shu)(shu)(shu)(shu)。對于(yu)拉(la)(la)深(shen)件，應(ying)結合板材的學科(ke)變(bian)(bian)形和(he)尺寸因素計算拉(la)(la)深(shen)次數(shu)(shu)(shu)(shu)，而彎曲件和(he)翻邊件應(ying)注意(yi)(yi)結合極限變(bian)(bian)形程(cheng)度和(he)具(ju)體形狀計算沖(chong)壓次數(shu)(shu)(shu)(shu)，避免減(jian)少工(gong)序(xu)數(shu)(shu)(shu)(shu)量(liang)，注意(yi)(yi)充分發揮材料的塑性作用，結合工(gong)藝質量(liang)要求和(he)變(bian)(bian)形特(te)點安排沖(chong)壓順序(xu)，從這些方(fang)面加強，有(you)助(zhu)于(yu)有(you)效控(kong)制各項工(gong)作質量(liang)。

　　此外，在(zai)沖壓件(jian)制造的(de)工(gong)(gong)藝組(zu)合(he)(he)過程中(zhong)，應選擇合(he)(he)適的(de)方法。沖壓件(jian)的(de)完成需要多(duo)個工(gong)(gong)序，因此編制工(gong)(gong)藝方案更為重要。考慮(lv)工(gong)(gong)藝，注意多(duo)工(gong)(gong)序組(zu)合(he)(he)、單工(gong)(gong)序組(zu)合(he)(he)、連續(xu)模(mo)具生(sheng)產和(he)復合(he)(he)模(mo)具生(sheng)產。

　　沖壓(ya)件的(de)(de)精度要(yao)求和零(ling)件尺寸是(shi)選(xuan)擇(ze)模(mo)具(ju)的(de)(de)重要(yao)參考要(yao)素。大規模(mo)生產應(ying)能夠結合沖壓(ya)工(gong)(gong)藝(yi)，連(lian)續模(mo)具(ju)沖壓(ya)和復合模(mo)具(ju)的(de)(de)選(xuan)擇(ze)更為(wei)合適。如果是(shi)小批量生產，有必要(yao)選(xuan)擇(ze)一個(ge)簡單的(de)(de)模(mo)具(ju)。當沖壓(ya)件尺寸相對較小時，應(ying)充分考慮單工(gong)(gong)藝(yi)模(mo)具(ju)的(de)(de)不便(bian)生產率，以(yi)(yi)復合模(mo)具(ju)或連(lian)續模(mo)具(ju)為(wei)主要(yao)方式。自動進料(liao)應(ying)以(yi)(yi)連(lian)續模(mo)式為(wei)主，做好工(gong)(gong)藝(yi)的(de)(de)科學組合，以(yi)(yi)提高工(gong)(gong)藝(yi)的(de)(de)應(ying)用(yong)效率。

　　此外，我們應該更加注(zhu)意工(gong)(gong)(gong)(gong)(gong)藝(yi)方(fang)案的確(que)(que)定和(he)設計。根(gen)據零件成(cheng)(cheng)型工(gong)(gong)(gong)(gong)(gong)藝(yi)方(fang)案的基(ji)礎上(shang)，明(ming)確(que)(que)各(ge)(ge)沖壓工(gong)(gong)(gong)(gong)(gong)藝(yi)方(fang)案。在內容方(fang)面(mian)，要注(zhu)意工(gong)(gong)(gong)(gong)(gong)藝(yi)成(cheng)(cheng)型和(he)加工(gong)(gong)(gong)(gong)(gong)方(fang)案的確(que)(que)定，明(ming)確(que)(que)工(gong)(gong)(gong)(gong)(gong)藝(yi)參數和(he)沖壓工(gong)(gong)(gong)(gong)(gong)藝(yi)的成(cheng)(cheng)型細節，如控制一次(ci)操作的翻邊高(gao)度、彎(wan)曲(qu)件的彎(wan)曲(qu)半徑(jing)等，還要注(zhu)意工(gong)(gong)(gong)(gong)(gong)藝(yi)成(cheng)(cheng)型力的確(que)(que)定，并結合實(shi)際計算對各(ge)(ge)工(gong)(gong)(gong)(gong)(gong)序工(gong)(gong)(gong)(gong)(gong)件圖進行(xing)描述，從整體上(shang)提高(gao)工(gong)(gong)(gong)(gong)(gong)藝(yi)質量。
