拖(tuo)泵(beng)制造工藝
錐(zhui)齒輪加工工藝流程(cheng)和難點控制
為確保齒(chi)(chi)(chi)輪(lun)熱處理(li)時(shi),能夠減小變形并(bing)獲得(de)均勻的組(zu)織和較(jiao)好的機(ji)械性(xing)能,在(zai)機(ji)加(jia)(jia)工(gong)(gong)前(qian),先(xian) 對齒(chi)(chi)(chi)坯進行高(gao)溫正(zheng)火(huo)(huo)(huo)(huo)(huo)預(yu)處理(li),可以使組(zu)織得(de)到細化(hua),并(bing)減小滲(shen)碳淬火(huo)(huo)(huo)(huo)(huo)時(shi)零件的變形,同時(shi)還有(you)利于 提高(gao)切削(xue)性(xing)能。正(zheng)火(huo)(huo)(huo)(huo)(huo)后(hou)轉機(ji)加(jia)(jia)工(gong)(gong),先(xian)在(zai)車(che)床上(shang)對齒(chi)(chi)(chi)坯外圓、端面進行粗、精加(jia)(jia)工(gong)(gong)后(hou),在(zai)臥式銑(xian)床上(shang)進 行銑(xian)齒(chi)(chi)(chi),然(ran)后(hou)在(zai)插(cha)(cha)床上(shang)插(cha)(cha)鍵槽,全部機(ji)加(jia)(jia)工(gong)(gong)完成后(hou),進行滲(shen)碳淬火(huo)(huo)(huo)(huo)(huo)和低溫回火(huo)(huo)(huo)(huo)(huo)處理(li),進行后(hou)序處 理(li)。該零件的工(gong)(gong)藝流(liu)程(cheng)為:正(zheng)火(huo)(huo)(huo)(huo)(huo)→車(che)削(xue)→銑(xian)齒(chi)(chi)(chi)→插(cha)(cha)鍵槽→滲(shen)碳淬火(huo)(huo)(huo)(huo)(huo)及退火(huo)(huo)(huo)(huo)(huo)→噴砂→防(fang)銹處理(li)。工(gong)(gong)藝難點為銑(xian)齒(chi)(chi)(chi)和熱處理(li)工(gong)(gong)序。
