拖泵(beng)制造工藝
錐齒(chi)輪(lun)加工(gong)(gong)工(gong)(gong)藝(yi)流程和難點控制
為確(que)保齒(chi)輪熱(re)處理(li)(li)時(shi),能(neng)夠(gou)減(jian)(jian)小(xiao)變形并獲得均(jun)勻的(de)(de)組織和(he)較好的(de)(de)機械性(xing)能(neng),在(zai)機加(jia)(jia)(jia)工(gong)前,先 對齒(chi)坯(pi)進(jin)(jin)(jin)行(xing)高溫(wen)(wen)正火(huo)預處理(li)(li),可以使組織得到(dao)細(xi)化,并減(jian)(jian)小(xiao)滲碳(tan)淬(cui)火(huo)時(shi)零(ling)件的(de)(de)變形,同時(shi)還有利于 提高切削性(xing)能(neng)。正火(huo)后(hou)轉機加(jia)(jia)(jia)工(gong),先在(zai)車(che)床(chuang)上對齒(chi)坯(pi)外圓、端(duan)面進(jin)(jin)(jin)行(xing)粗、精加(jia)(jia)(jia)工(gong)后(hou),在(zai)臥(wo)式銑(xian)床(chuang)上進(jin)(jin)(jin) 行(xing)銑(xian)齒(chi),然后(hou)在(zai)插床(chuang)上插鍵槽,全部機加(jia)(jia)(jia)工(gong)完成后(hou),進(jin)(jin)(jin)行(xing)滲碳(tan)淬(cui)火(huo)和(he)低溫(wen)(wen)回火(huo)處理(li)(li),進(jin)(jin)(jin)行(xing)后(hou)序處 理(li)(li)。該零(ling)件的(de)(de)工(gong)藝流(liu)程為:正火(huo)→車(che)削→銑(xian)齒(chi)→插鍵槽→滲碳(tan)淬(cui)火(huo)及退火(huo)→噴(pen)砂(sha)→防銹(xiu)處理(li)(li)。工(gong)藝難點為銑(xian)齒(chi)和(he)熱(re)處理(li)(li)工(gong)序。
