錐齒輪(lun)加工工藝流程和(he)難(nan)點控制

為(wei)確保齒(chi)輪(lun)熱(re)處(chu)(chu)理(li)時(shi)，能(neng)(neng)夠減小變形并獲(huo)得均勻的組(zu)織和(he)較好的機(ji)械性(xing)能(neng)(neng)，在機(ji)加(jia)工(gong)(gong)(gong)前，先 對齒(chi)坯(pi)進(jin)行(xing)高溫(wen)正火(huo)預(yu)處(chu)(chu)理(li)，可以使組(zu)織得到細化，并減小滲(shen)(shen)(shen)碳(tan)(tan)淬(cui)火(huo)時(shi)零件(jian)(jian)的變形，同時(shi)還有利(li)于 提高切削性(xing)能(neng)(neng)。正火(huo)后轉(zhuan)機(ji)加(jia)工(gong)(gong)(gong)，先在車床(chuang)上(shang)對齒(chi)坯(pi)外圓、端面進(jin)行(xing)粗、精(jing)加(jia)工(gong)(gong)(gong)后，在臥(wo)式銑床(chuang)上(shang)進(jin) 行(xing)銑齒(chi)，然后在插床(chuang)上(shang)插鍵槽，全部機(ji)加(jia)工(gong)(gong)(gong)完成(cheng)后，進(jin)行(xing)滲(shen)(shen)(shen)碳(tan)(tan)淬(cui)火(huo)和(he)低溫(wen)回(hui)火(huo)處(chu)(chu)理(li)，進(jin)行(xing)后序處(chu)(chu) 理(li)。該(gai)零件(jian)(jian)的工(gong)(gong)(gong)藝流程為(wei)：正火(huo)→車削→銑齒(chi)→插鍵槽→滲(shen)(shen)(shen)碳(tan)(tan)淬(cui)火(huo)及退火(huo)→噴砂→防(fang)銹處(chu)(chu)理(li)。工(gong)(gong)(gong)藝難點為(wei)銑齒(chi)和(he)熱(re)處(chu)(chu)理(li)工(gong)(gong)(gong)序。
