拖泵制造工藝
錐齒(chi)輪加工工藝流(liu)程和難點控制
為確(que)保齒(chi)(chi)(chi)輪熱(re)處(chu)理時,能夠減小變形并(bing)獲得均(jun)勻(yun)的(de)組(zu)織和較好的(de)機(ji)(ji)械性能,在(zai)(zai)機(ji)(ji)加(jia)(jia)(jia)工(gong)(gong)前(qian),先 對齒(chi)(chi)(chi)坯進行高溫正火(huo)(huo)預處(chu)理,可以使(shi)組(zu)織得到細化,并(bing)減小滲碳淬火(huo)(huo)時零(ling)件的(de)變形,同(tong)時還有利于 提高切削性能。正火(huo)(huo)后(hou)轉機(ji)(ji)加(jia)(jia)(jia)工(gong)(gong),先在(zai)(zai)車床(chuang)上對齒(chi)(chi)(chi)坯外(wai)圓、端(duan)面進行粗(cu)、精(jing)加(jia)(jia)(jia)工(gong)(gong)后(hou),在(zai)(zai)臥(wo)式銑床(chuang)上進 行銑齒(chi)(chi)(chi),然后(hou)在(zai)(zai)插(cha)床(chuang)上插(cha)鍵槽,全部機(ji)(ji)加(jia)(jia)(jia)工(gong)(gong)完(wan)成后(hou),進行滲碳淬火(huo)(huo)和低溫回火(huo)(huo)處(chu)理,進行后(hou)序處(chu) 理。該零(ling)件的(de)工(gong)(gong)藝(yi)流(liu)程為:正火(huo)(huo)→車削→銑齒(chi)(chi)(chi)→插(cha)鍵槽→滲碳淬火(huo)(huo)及退火(huo)(huo)→噴砂→防銹處(chu)理。工(gong)(gong)藝(yi)難(nan)點為銑齒(chi)(chi)(chi)和熱(re)處(chu)理工(gong)(gong)序。
