近(jin)日，中(zhong)國重(zhong)汽集團橋箱公(gong)司MAN錐齒(chi)(chi)輪(lun)自動線(xian)(xian)實現效(xiao)率(lv)提(ti)升(sheng)(sheng)，通(tong)過(guo)加(jia)工(gong)(gong)參數(shu)優化，成功(gong)(gong)奪回“黃金30秒(miao)(miao)”。MAN錐齒(chi)(chi)輪(lun)全(quan)自動加(jia)工(gong)(gong)線(xian)(xian)自投入使用的(de)(de)一年多時(shi)間里，以(yi)其穩定、智能、高(gao)效(xiao)的(de)(de)特點，為MAN錐齒(chi)(chi)輪(lun)生產(chan)(chan)(chan)做出了(le)很(hen)大貢獻。但(dan)在(zai)齒(chi)(chi)輪(lun)加(jia)工(gong)(gong)過(guo)程中(zhong)，鉆孔工(gong)(gong)序(xu)一直被(bei)視為生產(chan)(chan)(chan)效(xiao)率(lv)的(de)(de)瓶頸，該工(gong)(gong)序(xu)的(de)(de)加(jia)工(gong)(gong)效(xiao)率(lv)每延遲一秒(miao)(miao)，整個生產(chan)(chan)(chan)線(xian)(xian)的(de)(de)單件(jian)下(xia)線(xian)(xian)時(shi)間也(ye)(ye)就延長一秒(miao)(miao)。針對這(zhe)一問題，齒(chi)(chi)輪(lun)加(jia)工(gong)(gong)部(bu)技(ji)術人(ren)員想過(guo)很(hen)多辦法，嘗(chang)試(shi)過(guo)很(hen)多種方式(shi)，但(dan)是(shi)收效(xiao)均布明顯(xian)。但(dan)在(zai)近(jin)期(qi)嘗(chang)試(shi)調整鉆孔的(de)(de)切削(xue)參數(shu)中(zhong)，取(qu)得(de)突破性(xing)進展。適當(dang)提(ti)高(gao)轉(zhuan)速，同時(shi)將進給(gei)速度從450mm/min提(ti)升(sheng)(sheng)到550mm/min，經過(guo)反復試(shi)驗(yan)，切削(xue)參數(shu)的(de)(de)修改并沒(mei)有影響產(chan)(chan)(chan)品的(de)(de)加(jia)工(gong)(gong)質量(liang)和刀具的(de)(de)使用壽(shou)命(ming)，加(jia)工(gong)(gong)時(shi)間卻成功(gong)(gong)縮(suo)短近(jin)30秒(miao)(miao)。也(ye)(ye)就是(shi)說，齒(chi)(chi)輪(lun)的(de)(de)單件(jian)下(xia)線(xian)(xian)時(shi)間縮(suo)短了(le)30秒(miao)(miao)，其他工(gong)(gong)序(xu)的(de)(de)等待時(shi)間也(ye)(ye)縮(suo)短了(le)30秒(miao)(miao)。每班產(chan)(chan)(chan)品下(xia)線(xian)(xian)數(shu)從55件(jian)增(zeng)加(jia)到65件(jian)，提(ti)高(gao)了(le)生產(chan)(chan)(chan)效(xiao)率(lv)。
