錐齒輪加(jia)工工藝流程和難點控制

為確保齒(chi)(chi)(chi)(chi)輪熱處(chu)理(li)時(shi)，能夠減(jian)小變(bian)形(xing)并(bing)獲得均勻的組織和(he)較好(hao)的機械性能，在(zai)機加(jia)(jia)(jia)工(gong)(gong)前，先(xian) 對(dui)齒(chi)(chi)(chi)(chi)坯進(jin)(jin)行(xing)高溫正火(huo)(huo)(huo)預處(chu)理(li)，可以使組織得到細(xi)化，并(bing)減(jian)小滲碳(tan)淬火(huo)(huo)(huo)時(shi)零件的變(bian)形(xing)，同時(shi)還有利于(yu) 提高切削(xue)(xue)性能。正火(huo)(huo)(huo)后轉(zhuan)機加(jia)(jia)(jia)工(gong)(gong)，先(xian)在(zai)車(che)床上對(dui)齒(chi)(chi)(chi)(chi)坯外圓、端面進(jin)(jin)行(xing)粗、精(jing)加(jia)(jia)(jia)工(gong)(gong)后，在(zai)臥式銑(xian)床上進(jin)(jin) 行(xing)銑(xian)齒(chi)(chi)(chi)(chi)，然后在(zai)插(cha)床上插(cha)鍵槽，全部(bu)機加(jia)(jia)(jia)工(gong)(gong)完(wan)成后，進(jin)(jin)行(xing)滲碳(tan)淬火(huo)(huo)(huo)和(he)低溫回火(huo)(huo)(huo)處(chu)理(li)，進(jin)(jin)行(xing)后序(xu)處(chu) 理(li)。該零件的工(gong)(gong)藝流程為：正火(huo)(huo)(huo)→車(che)削(xue)(xue)→銑(xian)齒(chi)(chi)(chi)(chi)→插(cha)鍵槽→滲碳(tan)淬火(huo)(huo)(huo)及退火(huo)(huo)(huo)→噴(pen)砂→防(fang)銹處(chu)理(li)。工(gong)(gong)藝難點為銑(xian)齒(chi)(chi)(chi)(chi)和(he)熱處(chu)理(li)工(gong)(gong)序(xu)。
