錐齒輪加工(gong)工(gong)藝流程和難點控(kong)制

為(wei)(wei)確保齒(chi)輪熱處(chu)理(li)時(shi)，能夠減(jian)小變(bian)形(xing)并獲得(de)均勻的(de)組(zu)織和較好的(de)機(ji)械性能，在(zai)機(ji)加(jia)工(gong)(gong)前(qian)，先 對齒(chi)坯進(jin)行(xing)高(gao)溫正火(huo)(huo)(huo)預處(chu)理(li)，可以使組(zu)織得(de)到細化，并減(jian)小滲碳淬火(huo)(huo)(huo)時(shi)零件(jian)的(de)變(bian)形(xing)，同(tong)時(shi)還有利于 提(ti)高(gao)切削性能。正火(huo)(huo)(huo)后轉機(ji)加(jia)工(gong)(gong)，先在(zai)車(che)床上(shang)對齒(chi)坯外圓(yuan)、端面進(jin)行(xing)粗、精(jing)加(jia)工(gong)(gong)后，在(zai)臥式銑(xian)床上(shang)進(jin) 行(xing)銑(xian)齒(chi)，然(ran)后在(zai)插(cha)床上(shang)插(cha)鍵槽，全部(bu)機(ji)加(jia)工(gong)(gong)完成后，進(jin)行(xing)滲碳淬火(huo)(huo)(huo)和低溫回火(huo)(huo)(huo)處(chu)理(li)，進(jin)行(xing)后序處(chu) 理(li)。該零件(jian)的(de)工(gong)(gong)藝流程為(wei)(wei)：正火(huo)(huo)(huo)→車(che)削→銑(xian)齒(chi)→插(cha)鍵槽→滲碳淬火(huo)(huo)(huo)及退(tui)火(huo)(huo)(huo)→噴砂→防銹處(chu)理(li)。工(gong)(gong)藝難點為(wei)(wei)銑(xian)齒(chi)和熱處(chu)理(li)工(gong)(gong)序。
