錐齒(chi)輪加工工藝流程和難點控制
為(wei)(wei)確(que)保(bao)齒輪(lun)熱處理(li)時(shi),能(neng)夠減小變形(xing)并獲得均勻(yun)的(de)(de)組織(zhi)(zhi)和較好的(de)(de)機(ji)械性能(neng),在機(ji)加(jia)工(gong)(gong)(gong)前,先 對齒坯(pi)進行高(gao)溫(wen)正火預處理(li),可以(yi)使組織(zhi)(zhi)得到細(xi)化,并減小滲碳淬(cui)火時(shi)零(ling)件的(de)(de)變形(xing),同時(shi)還有利(li)于(yu) 提(ti)高(gao)切削(xue)性能(neng)。正火后(hou)轉機(ji)加(jia)工(gong)(gong)(gong),先在車(che)床上(shang)對齒坯(pi)外圓、端面進行粗、精加(jia)工(gong)(gong)(gong)后(hou),在臥式銑(xian)床上(shang)進 行銑(xian)齒,然后(hou)在插床上(shang)插鍵槽(cao),全部(bu)機(ji)加(jia)工(gong)(gong)(gong)完成(cheng)后(hou),進行滲碳淬(cui)火和低(di)溫(wen)回火處理(li),進行后(hou)序(xu)處 理(li)。該零(ling)件的(de)(de)工(gong)(gong)(gong)藝(yi)流程(cheng)為(wei)(wei):正火→車(che)削(xue)→銑(xian)齒→插鍵槽(cao)→滲碳淬(cui)火及退火→噴砂(sha)→防(fang)銹處理(li)。工(gong)(gong)(gong)藝(yi)難(nan)點為(wei)(wei)銑(xian)齒和熱處理(li)工(gong)(gong)(gong)序(xu)。
