拖泵制(zhi)造工藝
錐(zhui)齒(chi)輪加工工藝流(liu)程和(he)難(nan)點(dian)控制
為確(que)保齒輪(lun)熱處(chu)理(li)時,能夠減(jian)小(xiao)變形并獲得(de)均(jun)勻的(de)組織(zhi)(zhi)和較好的(de)機械性能,在(zai)機加工(gong)(gong)前,先(xian)(xian) 對齒坯進行高溫(wen)正(zheng)(zheng)火(huo)(huo)預處(chu)理(li),可以使組織(zhi)(zhi)得(de)到細化,并減(jian)小(xiao)滲碳(tan)(tan)淬(cui)(cui)火(huo)(huo)時零件的(de)變形,同(tong)時還有利(li)于 提(ti)高切削性能。正(zheng)(zheng)火(huo)(huo)后(hou)轉機加工(gong)(gong),先(xian)(xian)在(zai)車床上對齒坯外圓、端面進行粗、精(jing)加工(gong)(gong)后(hou),在(zai)臥式銑床上進 行銑齒,然(ran)后(hou)在(zai)插(cha)床上插(cha)鍵槽(cao),全部(bu)機加工(gong)(gong)完成后(hou),進行滲碳(tan)(tan)淬(cui)(cui)火(huo)(huo)和低溫(wen)回火(huo)(huo)處(chu)理(li),進行后(hou)序處(chu) 理(li)。該零件的(de)工(gong)(gong)藝流程為:正(zheng)(zheng)火(huo)(huo)→車削→銑齒→插(cha)鍵槽(cao)→滲碳(tan)(tan)淬(cui)(cui)火(huo)(huo)及退火(huo)(huo)→噴砂→防銹(xiu)處(chu)理(li)。工(gong)(gong)藝難點(dian)為銑齒和熱處(chu)理(li)工(gong)(gong)序。
