錐齒(chi)輪(lun)加工工藝流程(cheng)和(he)難點控制
為確保齒(chi)(chi)(chi)輪熱處(chu)理(li)(li)時,能(neng)夠減小變(bian)形并(bing)獲得均勻的(de)組(zu)織和(he)較好(hao)的(de)機(ji)械性能(neng),在(zai)機(ji)加工(gong)前,先 對齒(chi)(chi)(chi)坯進(jin)行(xing)高(gao)溫正火(huo)預(yu)處(chu)理(li)(li),可以使(shi)組(zu)織得到細化,并(bing)減小滲(shen)(shen)碳(tan)(tan)淬(cui)火(huo)時零(ling)件(jian)的(de)變(bian)形,同時還有利于 提高(gao)切削性能(neng)。正火(huo)后(hou)(hou)轉機(ji)加工(gong),先在(zai)車床(chuang)(chuang)上(shang)對齒(chi)(chi)(chi)坯外圓(yuan)、端面(mian)進(jin)行(xing)粗、精加工(gong)后(hou)(hou),在(zai)臥式(shi)銑(xian)床(chuang)(chuang)上(shang)進(jin) 行(xing)銑(xian)齒(chi)(chi)(chi),然后(hou)(hou)在(zai)插(cha)床(chuang)(chuang)上(shang)插(cha)鍵槽(cao),全部機(ji)加工(gong)完成(cheng)后(hou)(hou),進(jin)行(xing)滲(shen)(shen)碳(tan)(tan)淬(cui)火(huo)和(he)低溫回火(huo)處(chu)理(li)(li),進(jin)行(xing)后(hou)(hou)序處(chu) 理(li)(li)。該(gai)零(ling)件(jian)的(de)工(gong)藝流程為:正火(huo)→車削→銑(xian)齒(chi)(chi)(chi)→插(cha)鍵槽(cao)→滲(shen)(shen)碳(tan)(tan)淬(cui)火(huo)及退火(huo)→噴砂→防銹處(chu)理(li)(li)。工(gong)藝難點為銑(xian)齒(chi)(chi)(chi)和(he)熱處(chu)理(li)(li)工(gong)序。
