錐(zhui)齒輪加工(gong)(gong)工(gong)(gong)藝流程(cheng)和難點控制
為確保齒(chi)輪熱處(chu)(chu)理(li)時(shi),能夠(gou)減小(xiao)變形并(bing)(bing)獲得均勻的組織(zhi)和(he)較好的機(ji)械(xie)性能,在(zai)(zai)機(ji)加(jia)工前(qian),先(xian)(xian) 對齒(chi)坯(pi)進(jin)行(xing)高溫(wen)正火(huo)(huo)(huo)(huo)預處(chu)(chu)理(li),可以使組織(zhi)得到細(xi)化(hua),并(bing)(bing)減小(xiao)滲碳(tan)淬火(huo)(huo)(huo)(huo)時(shi)零件(jian)的變形,同(tong)時(shi)還有利于 提高切(qie)削(xue)性能。正火(huo)(huo)(huo)(huo)后(hou)轉機(ji)加(jia)工,先(xian)(xian)在(zai)(zai)車(che)床上對齒(chi)坯(pi)外圓、端面進(jin)行(xing)粗、精加(jia)工后(hou),在(zai)(zai)臥式銑床上進(jin) 行(xing)銑齒(chi),然(ran)后(hou)在(zai)(zai)插床上插鍵(jian)槽,全部機(ji)加(jia)工完成(cheng)后(hou),進(jin)行(xing)滲碳(tan)淬火(huo)(huo)(huo)(huo)和(he)低溫(wen)回(hui)火(huo)(huo)(huo)(huo)處(chu)(chu)理(li),進(jin)行(xing)后(hou)序處(chu)(chu) 理(li)。該零件(jian)的工藝流程為:正火(huo)(huo)(huo)(huo)→車(che)削(xue)→銑齒(chi)→插鍵(jian)槽→滲碳(tan)淬火(huo)(huo)(huo)(huo)及退火(huo)(huo)(huo)(huo)→噴砂→防銹處(chu)(chu)理(li)。工藝難點為銑齒(chi)和(he)熱處(chu)(chu)理(li)工序。
