錐齒(chi)輪加工工藝流程和難點控制
為(wei)(wei)確(que)保齒(chi)輪熱(re)處理時,能夠減小(xiao)變形并獲得均勻(yun)的(de)組(zu)織和較好的(de)機(ji)(ji)(ji)械(xie)性能,在(zai)機(ji)(ji)(ji)加工(gong)(gong)前(qian),先 對齒(chi)坯進(jin)行(xing)(xing)高溫(wen)(wen)正火(huo)(huo)預處理,可以(yi)使(shi)組(zu)織得到細(xi)化,并減小(xiao)滲碳(tan)淬火(huo)(huo)時零件的(de)變形,同時還有利(li)于 提高切(qie)削性能。正火(huo)(huo)后轉機(ji)(ji)(ji)加工(gong)(gong),先在(zai)車床(chuang)上對齒(chi)坯外圓、端面進(jin)行(xing)(xing)粗、精(jing)加工(gong)(gong)后,在(zai)臥式銑床(chuang)上進(jin) 行(xing)(xing)銑齒(chi),然(ran)后在(zai)插(cha)(cha)床(chuang)上插(cha)(cha)鍵槽(cao),全部(bu)機(ji)(ji)(ji)加工(gong)(gong)完成后,進(jin)行(xing)(xing)滲碳(tan)淬火(huo)(huo)和低溫(wen)(wen)回(hui)火(huo)(huo)處理,進(jin)行(xing)(xing)后序(xu)處 理。該(gai)零件的(de)工(gong)(gong)藝流程為(wei)(wei):正火(huo)(huo)→車削→銑齒(chi)→插(cha)(cha)鍵槽(cao)→滲碳(tan)淬火(huo)(huo)及(ji)退(tui)火(huo)(huo)→噴砂→防銹(xiu)處理。工(gong)(gong)藝難點為(wei)(wei)銑齒(chi)和熱(re)處理工(gong)(gong)序(xu)。
