錐(zhui)齒輪加工工藝流(liu)程和難點控制(zhi)

為確(que)保(bao)齒(chi)(chi)輪熱處(chu)(chu)理(li)(li)時，能夠減(jian)小(xiao)變形并獲(huo)得(de)均勻的組(zu)織和較(jiao)好的機械(xie)性能，在(zai)機加工(gong)(gong)前，先 對(dui)齒(chi)(chi)坯(pi)進行(xing)(xing)(xing)(xing)高(gao)溫(wen)正火(huo)預(yu)處(chu)(chu)理(li)(li)，可以使(shi)組(zu)織得(de)到細(xi)化，并減(jian)小(xiao)滲碳淬(cui)(cui)火(huo)時零件的變形，同時還有利于 提高(gao)切(qie)削性能。正火(huo)后(hou)轉(zhuan)機加工(gong)(gong)，先在(zai)車(che)床(chuang)上(shang)(shang)對(dui)齒(chi)(chi)坯(pi)外(wai)圓、端面進行(xing)(xing)(xing)(xing)粗、精加工(gong)(gong)后(hou)，在(zai)臥式銑床(chuang)上(shang)(shang)進 行(xing)(xing)(xing)(xing)銑齒(chi)(chi)，然(ran)后(hou)在(zai)插床(chuang)上(shang)(shang)插鍵槽，全部機加工(gong)(gong)完成后(hou)，進行(xing)(xing)(xing)(xing)滲碳淬(cui)(cui)火(huo)和低溫(wen)回火(huo)處(chu)(chu)理(li)(li)，進行(xing)(xing)(xing)(xing)后(hou)序(xu)處(chu)(chu) 理(li)(li)。該零件的工(gong)(gong)藝流程為：正火(huo)→車(che)削→銑齒(chi)(chi)→插鍵槽→滲碳淬(cui)(cui)火(huo)及退(tui)火(huo)→噴砂→防銹處(chu)(chu)理(li)(li)。工(gong)(gong)藝難點(dian)為銑齒(chi)(chi)和熱處(chu)(chu)理(li)(li)工(gong)(gong)序(xu)。
