錐齒輪加工工藝流程(cheng)和難點控制(zhi)
為確保齒輪熱處理(li)時(shi),能(neng)夠(gou)減小變(bian)形(xing)并獲得均勻的(de)組織(zhi)和(he)較好(hao)的(de)機(ji)械性(xing)(xing)能(neng),在(zai)機(ji)加(jia)工(gong)(gong)前,先(xian)(xian) 對齒坯(pi)進(jin)(jin)行(xing)(xing)高溫(wen)正火(huo)預處理(li),可以使組織(zhi)得到細化,并減小滲碳(tan)淬(cui)(cui)火(huo)時(shi)零件的(de)變(bian)形(xing),同時(shi)還有利于 提高切(qie)削(xue)性(xing)(xing)能(neng)。正火(huo)后轉機(ji)加(jia)工(gong)(gong),先(xian)(xian)在(zai)車(che)床(chuang)上對齒坯(pi)外圓(yuan)、端面進(jin)(jin)行(xing)(xing)粗、精加(jia)工(gong)(gong)后,在(zai)臥式銑床(chuang)上進(jin)(jin) 行(xing)(xing)銑齒,然后在(zai)插(cha)床(chuang)上插(cha)鍵槽,全部機(ji)加(jia)工(gong)(gong)完成后,進(jin)(jin)行(xing)(xing)滲碳(tan)淬(cui)(cui)火(huo)和(he)低溫(wen)回火(huo)處理(li),進(jin)(jin)行(xing)(xing)后序處 理(li)。該零件的(de)工(gong)(gong)藝流(liu)程為:正火(huo)→車(che)削(xue)→銑齒→插(cha)鍵槽→滲碳(tan)淬(cui)(cui)火(huo)及退(tui)火(huo)→噴砂→防銹(xiu)處理(li)。工(gong)(gong)藝難點為銑齒和(he)熱處理(li)工(gong)(gong)序。
