錐齒輪加(jia)工工藝流程和難點控制
為確保齒(chi)輪(lun)熱(re)處理(li)時,能夠減小變(bian)形并獲得(de)均(jun)勻的組(zu)織和較好(hao)的機械性(xing)能,在(zai)機加(jia)工(gong)(gong)前,先 對(dui)齒(chi)坯進(jin)(jin)行高溫正火(huo)(huo)預處理(li),可以使組(zu)織得(de)到細化,并減小滲(shen)碳(tan)淬(cui)火(huo)(huo)時零件的變(bian)形,同時還有利于 提高切削性(xing)能。正火(huo)(huo)后(hou)(hou)轉機加(jia)工(gong)(gong),先在(zai)車(che)床上對(dui)齒(chi)坯外圓、端面進(jin)(jin)行粗、精加(jia)工(gong)(gong)后(hou)(hou),在(zai)臥式銑床上進(jin)(jin) 行銑齒(chi),然后(hou)(hou)在(zai)插(cha)床上插(cha)鍵槽,全部機加(jia)工(gong)(gong)完成(cheng)后(hou)(hou),進(jin)(jin)行滲(shen)碳(tan)淬(cui)火(huo)(huo)和低溫回火(huo)(huo)處理(li),進(jin)(jin)行后(hou)(hou)序處 理(li)。該零件的工(gong)(gong)藝流程為:正火(huo)(huo)→車(che)削→銑齒(chi)→插(cha)鍵槽→滲(shen)碳(tan)淬(cui)火(huo)(huo)及(ji)退火(huo)(huo)→噴砂→防銹(xiu)處理(li)。工(gong)(gong)藝難點為銑齒(chi)和熱(re)處理(li)工(gong)(gong)序。
