錐齒輪加工工藝(yi)流(liu)程和難點控制
為確保齒(chi)(chi)輪熱處理(li)時,能(neng)夠減小變形(xing)并獲得(de)均勻的(de)組織(zhi)(zhi)和較好的(de)機(ji)械(xie)性能(neng),在機(ji)加(jia)工(gong)前,先(xian) 對齒(chi)(chi)坯(pi)進(jin)行(xing)(xing)(xing)高溫正(zheng)火(huo)(huo)(huo)預處理(li),可以使組織(zhi)(zhi)得(de)到細(xi)化,并減小滲(shen)(shen)碳淬火(huo)(huo)(huo)時零件的(de)變形(xing),同時還有利于 提高切削(xue)性能(neng)。正(zheng)火(huo)(huo)(huo)后轉機(ji)加(jia)工(gong),先(xian)在車床上(shang)對齒(chi)(chi)坯(pi)外圓、端面(mian)進(jin)行(xing)(xing)(xing)粗、精加(jia)工(gong)后,在臥(wo)式銑(xian)(xian)床上(shang)進(jin) 行(xing)(xing)(xing)銑(xian)(xian)齒(chi)(chi),然后在插(cha)(cha)床上(shang)插(cha)(cha)鍵槽,全(quan)部機(ji)加(jia)工(gong)完(wan)成后,進(jin)行(xing)(xing)(xing)滲(shen)(shen)碳淬火(huo)(huo)(huo)和低溫回火(huo)(huo)(huo)處理(li),進(jin)行(xing)(xing)(xing)后序處 理(li)。該零件的(de)工(gong)藝流程為:正(zheng)火(huo)(huo)(huo)→車削(xue)→銑(xian)(xian)齒(chi)(chi)→插(cha)(cha)鍵槽→滲(shen)(shen)碳淬火(huo)(huo)(huo)及退火(huo)(huo)(huo)→噴(pen)砂→防銹(xiu)處理(li)。工(gong)藝難點為銑(xian)(xian)齒(chi)(chi)和熱處理(li)工(gong)序。
