錐齒輪加(jia)工工藝(yi)流程和難點控制
為確保齒(chi)輪熱處理(li)(li)時,能夠減小變(bian)形并獲得均勻(yun)的組(zu)織(zhi)(zhi)和較好的機(ji)械性(xing)能,在機(ji)加工(gong)前,先 對齒(chi)坯進(jin)行(xing)(xing)高溫正(zheng)(zheng)火預處理(li)(li),可(ke)以使(shi)組(zu)織(zhi)(zhi)得到細化,并減小滲(shen)碳(tan)淬火時零(ling)件(jian)的變(bian)形,同時還有(you)利于 提高切削性(xing)能。正(zheng)(zheng)火后(hou)轉機(ji)加工(gong),先在車床上(shang)(shang)對齒(chi)坯外(wai)圓、端(duan)面進(jin)行(xing)(xing)粗、精加工(gong)后(hou),在臥(wo)式銑床上(shang)(shang)進(jin) 行(xing)(xing)銑齒(chi),然后(hou)在插(cha)床上(shang)(shang)插(cha)鍵(jian)槽,全部機(ji)加工(gong)完成(cheng)后(hou),進(jin)行(xing)(xing)滲(shen)碳(tan)淬火和低溫回火處理(li)(li),進(jin)行(xing)(xing)后(hou)序處 理(li)(li)。該(gai)零(ling)件(jian)的工(gong)藝流程(cheng)為:正(zheng)(zheng)火→車削→銑齒(chi)→插(cha)鍵(jian)槽→滲(shen)碳(tan)淬火及退火→噴(pen)砂→防(fang)銹(xiu)處理(li)(li)。工(gong)藝難(nan)點(dian)為銑齒(chi)和熱處理(li)(li)工(gong)序。
