錐齒(chi)輪加工工藝流程和(he)難點(dian)控制(zhi)
為確(que)保齒(chi)輪熱處(chu)理(li)(li)(li)時(shi)(shi),能(neng)夠減(jian)小變形并(bing)獲(huo)得(de)均勻的(de)組(zu)織(zhi)和(he)較好的(de)機(ji)械性能(neng),在(zai)(zai)機(ji)加(jia)(jia)工(gong)前,先(xian) 對齒(chi)坯進(jin)行(xing)高溫正(zheng)火(huo)預(yu)處(chu)理(li)(li)(li),可(ke)以使組(zu)織(zhi)得(de)到細化,并(bing)減(jian)小滲碳淬火(huo)時(shi)(shi)零件(jian)的(de)變形,同(tong)時(shi)(shi)還有(you)利于 提高切削性能(neng)。正(zheng)火(huo)后(hou)轉機(ji)加(jia)(jia)工(gong),先(xian)在(zai)(zai)車床(chuang)上(shang)(shang)對齒(chi)坯外圓、端面進(jin)行(xing)粗、精加(jia)(jia)工(gong)后(hou),在(zai)(zai)臥式銑(xian)床(chuang)上(shang)(shang)進(jin) 行(xing)銑(xian)齒(chi),然后(hou)在(zai)(zai)插床(chuang)上(shang)(shang)插鍵槽(cao),全部(bu)機(ji)加(jia)(jia)工(gong)完成后(hou),進(jin)行(xing)滲碳淬火(huo)和(he)低(di)溫回火(huo)處(chu)理(li)(li)(li),進(jin)行(xing)后(hou)序處(chu) 理(li)(li)(li)。該零件(jian)的(de)工(gong)藝(yi)流程為:正(zheng)火(huo)→車削→銑(xian)齒(chi)→插鍵槽(cao)→滲碳淬火(huo)及退火(huo)→噴砂(sha)→防(fang)銹處(chu)理(li)(li)(li)。工(gong)藝(yi)難(nan)點為銑(xian)齒(chi)和(he)熱處(chu)理(li)(li)(li)工(gong)序。
