錐齒(chi)輪加工工藝流(liu)程和難點控制

為確保齒(chi)(chi)輪熱處(chu)(chu)理(li)(li)(li)(li)(li)時(shi)(shi)，能(neng)夠減小變形(xing)并(bing)獲得均(jun)勻的(de)組織(zhi)和(he)較好(hao)的(de)機(ji)械性能(neng)，在機(ji)加(jia)工(gong)(gong)(gong)前，先 對(dui)齒(chi)(chi)坯進(jin)行高溫(wen)正(zheng)(zheng)火(huo)(huo)預處(chu)(chu)理(li)(li)(li)(li)(li)，可以使組織(zhi)得到細化，并(bing)減小滲碳淬(cui)火(huo)(huo)時(shi)(shi)零(ling)件的(de)變形(xing)，同時(shi)(shi)還有利于(yu) 提高切削(xue)性能(neng)。正(zheng)(zheng)火(huo)(huo)后(hou)(hou)轉(zhuan)機(ji)加(jia)工(gong)(gong)(gong)，先在車(che)床上(shang)(shang)對(dui)齒(chi)(chi)坯外圓、端面進(jin)行粗、精加(jia)工(gong)(gong)(gong)后(hou)(hou)，在臥式銑(xian)(xian)床上(shang)(shang)進(jin) 行銑(xian)(xian)齒(chi)(chi)，然后(hou)(hou)在插床上(shang)(shang)插鍵(jian)槽(cao)(cao)，全(quan)部機(ji)加(jia)工(gong)(gong)(gong)完(wan)成后(hou)(hou)，進(jin)行滲碳淬(cui)火(huo)(huo)和(he)低溫(wen)回火(huo)(huo)處(chu)(chu)理(li)(li)(li)(li)(li)，進(jin)行后(hou)(hou)序(xu)(xu)處(chu)(chu) 理(li)(li)(li)(li)(li)。該零(ling)件的(de)工(gong)(gong)(gong)藝流程為：正(zheng)(zheng)火(huo)(huo)→車(che)削(xue)→銑(xian)(xian)齒(chi)(chi)→插鍵(jian)槽(cao)(cao)→滲碳淬(cui)火(huo)(huo)及退火(huo)(huo)→噴(pen)砂(sha)→防(fang)銹處(chu)(chu)理(li)(li)(li)(li)(li)。工(gong)(gong)(gong)藝難(nan)點(dian)為銑(xian)(xian)齒(chi)(chi)和(he)熱處(chu)(chu)理(li)(li)(li)(li)(li)工(gong)(gong)(gong)序(xu)(xu)。
