錐齒(chi)輪加工(gong)工(gong)藝流程和難點控制

為(wei)確(que)保(bao)齒(chi)輪熱處(chu)(chu)理(li)時，能夠減(jian)小(xiao)(xiao)變(bian)形并獲得均勻的(de)組(zu)織和(he)較(jiao)好的(de)機(ji)械性能，在(zai)機(ji)加(jia)(jia)工(gong)(gong)(gong)前，先(xian)(xian) 對(dui)(dui)齒(chi)坯進(jin)行(xing)(xing)高(gao)溫正火(huo)(huo)(huo)預處(chu)(chu)理(li)，可以使組(zu)織得到細化(hua)，并減(jian)小(xiao)(xiao)滲(shen)(shen)碳淬火(huo)(huo)(huo)時零件(jian)的(de)變(bian)形，同時還有利于 提高(gao)切削性能。正火(huo)(huo)(huo)后(hou)轉機(ji)加(jia)(jia)工(gong)(gong)(gong)，先(xian)(xian)在(zai)車床上對(dui)(dui)齒(chi)坯外圓、端面進(jin)行(xing)(xing)粗、精加(jia)(jia)工(gong)(gong)(gong)后(hou)，在(zai)臥式(shi)銑床上進(jin) 行(xing)(xing)銑齒(chi)，然后(hou)在(zai)插(cha)(cha)(cha)床上插(cha)(cha)(cha)鍵槽(cao)，全部機(ji)加(jia)(jia)工(gong)(gong)(gong)完(wan)成后(hou)，進(jin)行(xing)(xing)滲(shen)(shen)碳淬火(huo)(huo)(huo)和(he)低溫回火(huo)(huo)(huo)處(chu)(chu)理(li)，進(jin)行(xing)(xing)后(hou)序處(chu)(chu) 理(li)。該零件(jian)的(de)工(gong)(gong)(gong)藝流程為(wei)：正火(huo)(huo)(huo)→車削→銑齒(chi)→插(cha)(cha)(cha)鍵槽(cao)→滲(shen)(shen)碳淬火(huo)(huo)(huo)及(ji)退火(huo)(huo)(huo)→噴砂(sha)→防銹處(chu)(chu)理(li)。工(gong)(gong)(gong)藝難點(dian)為(wei)銑齒(chi)和(he)熱處(chu)(chu)理(li)工(gong)(gong)(gong)序。
