錐(zhui)齒(chi)輪加工工藝流程(cheng)和(he)難點控制
為(wei)(wei)確保齒(chi)(chi)輪熱處(chu)(chu)(chu)理(li)時,能夠減(jian)小(xiao)(xiao)變(bian)形并獲得均勻的(de)組織(zhi)和(he)較好的(de)機械性(xing)(xing)能,在(zai)機加工(gong)前(qian),先 對齒(chi)(chi)坯(pi)進(jin)行(xing)高溫正火(huo)預處(chu)(chu)(chu)理(li),可以(yi)使組織(zhi)得到細化(hua),并減(jian)小(xiao)(xiao)滲碳(tan)淬(cui)(cui)火(huo)時零件的(de)變(bian)形,同時還有利(li)于 提高切削(xue)性(xing)(xing)能。正火(huo)后轉機加工(gong),先在(zai)車床上對齒(chi)(chi)坯(pi)外圓、端面進(jin)行(xing)粗(cu)、精加工(gong)后,在(zai)臥(wo)式(shi)銑(xian)床上進(jin) 行(xing)銑(xian)齒(chi)(chi),然后在(zai)插床上插鍵槽(cao),全部機加工(gong)完成后,進(jin)行(xing)滲碳(tan)淬(cui)(cui)火(huo)和(he)低(di)溫回火(huo)處(chu)(chu)(chu)理(li),進(jin)行(xing)后序(xu)處(chu)(chu)(chu) 理(li)。該(gai)零件的(de)工(gong)藝流程為(wei)(wei):正火(huo)→車削(xue)→銑(xian)齒(chi)(chi)→插鍵槽(cao)→滲碳(tan)淬(cui)(cui)火(huo)及退火(huo)→噴砂→防銹處(chu)(chu)(chu)理(li)。工(gong)藝難點為(wei)(wei)銑(xian)齒(chi)(chi)和(he)熱處(chu)(chu)(chu)理(li)工(gong)序(xu)。
