錐齒(chi)輪加工(gong)工(gong)藝流程和難點控(kong)制
為確保(bao)齒(chi)(chi)(chi)輪熱(re)處(chu)(chu)理(li)時(shi)(shi),能(neng)夠(gou)減小變形并獲得均勻的組織和較好(hao)的機(ji)(ji)械性(xing)能(neng),在(zai)(zai)機(ji)(ji)加工(gong)前(qian),先(xian) 對(dui)齒(chi)(chi)(chi)坯進行(xing)(xing)高(gao)溫(wen)正(zheng)火(huo)預處(chu)(chu)理(li),可以使(shi)組織得到細化,并減小滲(shen)碳(tan)淬火(huo)時(shi)(shi)零件的變形,同時(shi)(shi)還有利于 提高(gao)切削(xue)性(xing)能(neng)。正(zheng)火(huo)后轉機(ji)(ji)加工(gong),先(xian)在(zai)(zai)車床上對(dui)齒(chi)(chi)(chi)坯外(wai)圓、端(duan)面進行(xing)(xing)粗、精加工(gong)后,在(zai)(zai)臥式銑床上進 行(xing)(xing)銑齒(chi)(chi)(chi),然(ran)后在(zai)(zai)插床上插鍵槽(cao),全部(bu)機(ji)(ji)加工(gong)完成后,進行(xing)(xing)滲(shen)碳(tan)淬火(huo)和低(di)溫(wen)回火(huo)處(chu)(chu)理(li),進行(xing)(xing)后序處(chu)(chu) 理(li)。該(gai)零件的工(gong)藝流(liu)程為:正(zheng)火(huo)→車削(xue)→銑齒(chi)(chi)(chi)→插鍵槽(cao)→滲(shen)碳(tan)淬火(huo)及退(tui)火(huo)→噴砂→防銹處(chu)(chu)理(li)。工(gong)藝難點為銑齒(chi)(chi)(chi)和熱(re)處(chu)(chu)理(li)工(gong)序。
