錐齒(chi)輪加工工藝流程和(he)難點控制
為確保齒(chi)輪熱處(chu)(chu)(chu)理(li)時,能(neng)夠減(jian)小變(bian)形并獲得(de)均勻的組(zu)織和(he)較好的機(ji)(ji)(ji)械性(xing)能(neng),在(zai)(zai)機(ji)(ji)(ji)加工(gong)(gong)前,先(xian) 對齒(chi)坯(pi)進(jin)行高(gao)溫正火(huo)預處(chu)(chu)(chu)理(li),可以使組(zu)織得(de)到(dao)細化,并減(jian)小滲碳淬(cui)火(huo)時零件的變(bian)形,同(tong)時還有(you)利于 提高(gao)切削性(xing)能(neng)。正火(huo)后轉機(ji)(ji)(ji)加工(gong)(gong),先(xian)在(zai)(zai)車(che)床(chuang)上對齒(chi)坯(pi)外圓、端面(mian)進(jin)行粗、精加工(gong)(gong)后,在(zai)(zai)臥式銑床(chuang)上進(jin) 行銑齒(chi),然后在(zai)(zai)插(cha)(cha)床(chuang)上插(cha)(cha)鍵槽(cao),全部機(ji)(ji)(ji)加工(gong)(gong)完成后,進(jin)行滲碳淬(cui)火(huo)和(he)低溫回火(huo)處(chu)(chu)(chu)理(li),進(jin)行后序處(chu)(chu)(chu) 理(li)。該(gai)零件的工(gong)(gong)藝(yi)流程(cheng)為:正火(huo)→車(che)削→銑齒(chi)→插(cha)(cha)鍵槽(cao)→滲碳淬(cui)火(huo)及退火(huo)→噴砂→防銹處(chu)(chu)(chu)理(li)。工(gong)(gong)藝(yi)難點為銑齒(chi)和(he)熱處(chu)(chu)(chu)理(li)工(gong)(gong)序。
