錐齒輪加(jia)工工藝流程和(he)難點控制

為(wei)確保(bao)齒輪(lun)熱(re)處(chu)理(li)時，能夠減小變形(xing)并獲得(de)均勻的(de)組(zu)織(zhi)和較好(hao)的(de)機械(xie)性(xing)能，在(zai)(zai)機加工(gong)(gong)前(qian)，先(xian) 對齒坯進(jin)行(xing)高(gao)(gao)溫(wen)正(zheng)(zheng)火(huo)(huo)(huo)(huo)預(yu)處(chu)理(li)，可以使(shi)組(zu)織(zhi)得(de)到細化，并減小滲(shen)(shen)碳(tan)淬火(huo)(huo)(huo)(huo)時零件(jian)的(de)變形(xing)，同時還有(you)利于 提高(gao)(gao)切削(xue)(xue)性(xing)能。正(zheng)(zheng)火(huo)(huo)(huo)(huo)后(hou)轉機加工(gong)(gong)，先(xian)在(zai)(zai)車(che)床(chuang)(chuang)上對齒坯外(wai)圓(yuan)、端(duan)面進(jin)行(xing)粗、精加工(gong)(gong)后(hou)，在(zai)(zai)臥式銑床(chuang)(chuang)上進(jin) 行(xing)銑齒，然后(hou)在(zai)(zai)插床(chuang)(chuang)上插鍵(jian)槽，全部(bu)機加工(gong)(gong)完成(cheng)后(hou)，進(jin)行(xing)滲(shen)(shen)碳(tan)淬火(huo)(huo)(huo)(huo)和低溫(wen)回火(huo)(huo)(huo)(huo)處(chu)理(li)，進(jin)行(xing)后(hou)序處(chu) 理(li)。該(gai)零件(jian)的(de)工(gong)(gong)藝流程為(wei)：正(zheng)(zheng)火(huo)(huo)(huo)(huo)→車(che)削(xue)(xue)→銑齒→插鍵(jian)槽→滲(shen)(shen)碳(tan)淬火(huo)(huo)(huo)(huo)及(ji)退火(huo)(huo)(huo)(huo)→噴砂→防銹處(chu)理(li)。工(gong)(gong)藝難點為(wei)銑齒和熱(re)處(chu)理(li)工(gong)(gong)序。
