錐齒(chi)輪加(jia)工(gong)工(gong)藝流程和(he)難點控制
為(wei)確保齒(chi)(chi)(chi)(chi)輪熱處理(li)(li)時,能(neng)夠減(jian)小(xiao)變形并獲(huo)得(de)均勻的組織和較(jiao)好的機械性能(neng),在機加(jia)(jia)工前(qian),先 對(dui)齒(chi)(chi)(chi)(chi)坯進(jin)(jin)行(xing)高溫正(zheng)(zheng)火(huo)預處理(li)(li),可(ke)以使組織得(de)到細化,并減(jian)小(xiao)滲碳淬火(huo)時零件的變形,同(tong)時還有利于 提高切削性能(neng)。正(zheng)(zheng)火(huo)后轉機加(jia)(jia)工,先在車(che)床(chuang)上(shang)對(dui)齒(chi)(chi)(chi)(chi)坯外圓、端面進(jin)(jin)行(xing)粗(cu)、精(jing)加(jia)(jia)工后,在臥(wo)式銑(xian)床(chuang)上(shang)進(jin)(jin) 行(xing)銑(xian)齒(chi)(chi)(chi)(chi),然后在插床(chuang)上(shang)插鍵槽,全部機加(jia)(jia)工完(wan)成后,進(jin)(jin)行(xing)滲碳淬火(huo)和低(di)溫回火(huo)處理(li)(li),進(jin)(jin)行(xing)后序處 理(li)(li)。該(gai)零件的工藝流程(cheng)為(wei):正(zheng)(zheng)火(huo)→車(che)削→銑(xian)齒(chi)(chi)(chi)(chi)→插鍵槽→滲碳淬火(huo)及退火(huo)→噴砂→防銹處理(li)(li)。工藝難(nan)點為(wei)銑(xian)齒(chi)(chi)(chi)(chi)和熱處理(li)(li)工序。
