錐齒輪加工工藝流程和難點控制
為(wei)確(que)保齒(chi)輪熱處(chu)理時,能(neng)夠(gou)減小變形(xing)并獲(huo)得均勻的組織和較好的機械性(xing)能(neng),在(zai)機加(jia)工(gong)前,先 對(dui)齒(chi)坯進行(xing)高溫(wen)正火(huo)(huo)(huo)預處(chu)理,可以使(shi)組織得到(dao)細(xi)化,并減小滲(shen)(shen)(shen)碳淬(cui)火(huo)(huo)(huo)時零件(jian)的變形(xing),同(tong)時還有利(li)于 提高切(qie)削(xue)性(xing)能(neng)。正火(huo)(huo)(huo)后(hou)(hou)轉機加(jia)工(gong),先在(zai)車床上(shang)對(dui)齒(chi)坯外圓(yuan)、端(duan)面進行(xing)粗、精(jing)加(jia)工(gong)后(hou)(hou),在(zai)臥式銑(xian)(xian)床上(shang)進 行(xing)銑(xian)(xian)齒(chi),然后(hou)(hou)在(zai)插床上(shang)插鍵槽(cao),全部(bu)機加(jia)工(gong)完成后(hou)(hou),進行(xing)滲(shen)(shen)(shen)碳淬(cui)火(huo)(huo)(huo)和低溫(wen)回火(huo)(huo)(huo)處(chu)理,進行(xing)后(hou)(hou)序處(chu) 理。該(gai)零件(jian)的工(gong)藝(yi)流(liu)程為(wei):正火(huo)(huo)(huo)→車削(xue)→銑(xian)(xian)齒(chi)→插鍵槽(cao)→滲(shen)(shen)(shen)碳淬(cui)火(huo)(huo)(huo)及退火(huo)(huo)(huo)→噴砂→防銹處(chu)理。工(gong)藝(yi)難點為(wei)銑(xian)(xian)齒(chi)和熱處(chu)理工(gong)序。
