錐齒(chi)輪加工(gong)工(gong)藝流程(cheng)和難點控(kong)制
為確(que)保(bao)齒(chi)輪熱(re)處理(li)(li)(li)時,能夠減小變形(xing)并(bing)獲得均勻的組(zu)織(zhi)(zhi)和(he)較好的機(ji)械性(xing)(xing)能,在(zai)機(ji)加工(gong)(gong)前(qian),先(xian) 對齒(chi)坯進(jin)行高溫正火(huo)(huo)預處理(li)(li)(li),可以(yi)使(shi)組(zu)織(zhi)(zhi)得到細化,并(bing)減小滲碳淬火(huo)(huo)時零(ling)件的變形(xing),同時還有利于 提高切削(xue)性(xing)(xing)能。正火(huo)(huo)后(hou)轉機(ji)加工(gong)(gong),先(xian)在(zai)車(che)床(chuang)上(shang)(shang)對齒(chi)坯外圓(yuan)、端面進(jin)行粗、精(jing)加工(gong)(gong)后(hou),在(zai)臥(wo)式銑床(chuang)上(shang)(shang)進(jin) 行銑齒(chi),然后(hou)在(zai)插床(chuang)上(shang)(shang)插鍵槽(cao),全部機(ji)加工(gong)(gong)完成后(hou),進(jin)行滲碳淬火(huo)(huo)和(he)低溫回(hui)火(huo)(huo)處理(li)(li)(li),進(jin)行后(hou)序(xu)處 理(li)(li)(li)。該零(ling)件的工(gong)(gong)藝流(liu)程為:正火(huo)(huo)→車(che)削(xue)→銑齒(chi)→插鍵槽(cao)→滲碳淬火(huo)(huo)及退(tui)火(huo)(huo)→噴砂→防(fang)銹處理(li)(li)(li)。工(gong)(gong)藝難點為銑齒(chi)和(he)熱(re)處理(li)(li)(li)工(gong)(gong)序(xu)。
