錐齒(chi)輪加(jia)工工藝流程和難點控制(zhi)
為確保(bao)齒(chi)輪熱(re)處(chu)理(li)時(shi)(shi),能(neng)夠(gou)減(jian)小(xiao)變(bian)形并(bing)(bing)獲得均(jun)勻的組織和較好的機(ji)械性能(neng),在(zai)機(ji)加(jia)工(gong)前,先 對齒(chi)坯進(jin)行(xing)(xing)高(gao)溫(wen)正火(huo)預處(chu)理(li),可以(yi)使組織得到(dao)細化,并(bing)(bing)減(jian)小(xiao)滲碳(tan)淬(cui)火(huo)時(shi)(shi)零(ling)件的變(bian)形,同時(shi)(shi)還有利于 提高(gao)切削性能(neng)。正火(huo)后(hou)轉機(ji)加(jia)工(gong),先在(zai)車(che)床(chuang)上(shang)對齒(chi)坯外(wai)圓、端(duan)面進(jin)行(xing)(xing)粗(cu)、精加(jia)工(gong)后(hou),在(zai)臥(wo)式銑(xian)床(chuang)上(shang)進(jin) 行(xing)(xing)銑(xian)齒(chi),然后(hou)在(zai)插(cha)床(chuang)上(shang)插(cha)鍵槽,全部機(ji)加(jia)工(gong)完(wan)成后(hou),進(jin)行(xing)(xing)滲碳(tan)淬(cui)火(huo)和低(di)溫(wen)回火(huo)處(chu)理(li),進(jin)行(xing)(xing)后(hou)序處(chu) 理(li)。該零(ling)件的工(gong)藝流程為:正火(huo)→車(che)削→銑(xian)齒(chi)→插(cha)鍵槽→滲碳(tan)淬(cui)火(huo)及退火(huo)→噴砂→防銹處(chu)理(li)。工(gong)藝難點為銑(xian)齒(chi)和熱(re)處(chu)理(li)工(gong)序。
