任何一(yi)個五金(jin)沖壓(ya)件(jian),往(wang)往(wang)有(you)幾種不同的沖壓工藝方案(an),因此(ci)需(xu)要(yao)綜合(he)考量各(ge)方面的因素,并(bing)通過分(fen)析,比較(jiao)、從中(zhong)選擇一種在技術和經濟上都較(jiao)為合(he)理的zui佳(jia)方案(an)。
所謂zui佳(jia)工藝方案(an)是(shi)相(xiang)對而(er)言(yan),它與沖(chong)壓件(jian)生產廠家的(de)具體(ti)生(sheng)(sheng)產(chan)條(tiao)件(jian)有關。因(yin)此(ci)確定沖壓件(jian)的(de)工藝(yi)方(fang)案(an)時應從現有的(de)生(sheng)(sheng)產(chan)條(tiao)件(jian)出發,在保證產(chan)品(pin)質量和滿足生(sheng)(sheng)產(chan)批量要(yao)求(qiu)(qiu)的(de)前(qian)提下(xia),尋(xun)求(qiu)(qiu)以zui佳(jia)經(jing)濟合理(li)的(de)方(fang)式完(wan)成(cheng)沖壓件(jian)的(de)加(jia)工過程(cheng)。
此外還應注意,對某些(xie)組合沖壓(ya)件或(huo)有特殊要求的沖(chong)壓(ya)件,在分析(xi)了(le)工(gong)(gong)(gong)(gong)序(xu)(xu)性質(zhi)、數量、順序(xu)(xu)以及工(gong)(gong)(gong)(gong)序(xu)(xu)組合方式后(hou),還必須要(yao)(yao)考慮非沖壓(ya)輔助工(gong)(gong)(gong)(gong)序(xu)(xu),如鉆孔(kong)、車削(xue)等機械加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)(xu),焊接、鉚合、熱處理(li)、表面處理(li)、清理(li)和(he)去毛(mao)刺等工(gong)(gong)(gong)(gong)序(xu)(xu)。這些輔助工(gong)(gong)(gong)(gong)序(xu)(xu)應該(gai)根據沖壓(ya)件(jian)結構特點和(he)使(shi)用要(yao)(yao)求選用,有的(de)可(ke)安排在各(ge)沖壓(ya)工(gong)(gong)(gong)(gong)序(xu)(xu)之間進行(xing),有的(de)可(ke)置于沖壓(ya)工(gong)(gong)(gong)(gong)序(xu)(xu)后(hou)進行(xing),應視具體(ti)情況具體(ti)分析(xi)后(hou)做出(chu)安排。
