錐齒輪加工工藝流程(cheng)和難點(dian)控(kong)制

為確(que)保(bao)齒(chi)輪熱處(chu)(chu)(chu)(chu)理(li)時(shi)，能夠減小變形并獲得均勻的組織(zhi)和較好的機械性能，在(zai)機加工(gong)(gong)前，先(xian) 對(dui)齒(chi)坯進(jin)行(xing)(xing)高溫正(zheng)火(huo)預處(chu)(chu)(chu)(chu)理(li)，可(ke)以使組織(zhi)得到細化，并減小滲(shen)碳淬(cui)火(huo)時(shi)零件的變形，同時(shi)還有(you)利于 提(ti)高切(qie)削(xue)性能。正(zheng)火(huo)后(hou)(hou)轉(zhuan)機加工(gong)(gong)，先(xian)在(zai)車床上(shang)對(dui)齒(chi)坯外(wai)圓(yuan)、端面進(jin)行(xing)(xing)粗(cu)、精加工(gong)(gong)后(hou)(hou)，在(zai)臥式銑(xian)床上(shang)進(jin) 行(xing)(xing)銑(xian)齒(chi)，然后(hou)(hou)在(zai)插(cha)床上(shang)插(cha)鍵(jian)槽，全部機加工(gong)(gong)完成后(hou)(hou)，進(jin)行(xing)(xing)滲(shen)碳淬(cui)火(huo)和低(di)溫回火(huo)處(chu)(chu)(chu)(chu)理(li)，進(jin)行(xing)(xing)后(hou)(hou)序處(chu)(chu)(chu)(chu) 理(li)。該(gai)零件的工(gong)(gong)藝(yi)流程為：正(zheng)火(huo)→車削(xue)→銑(xian)齒(chi)→插(cha)鍵(jian)槽→滲(shen)碳淬(cui)火(huo)及退火(huo)→噴(pen)砂→防銹處(chu)(chu)(chu)(chu)理(li)。工(gong)(gong)藝(yi)難點為銑(xian)齒(chi)和熱處(chu)(chu)(chu)(chu)理(li)工(gong)(gong)序。
