數控機床鑄件作為機床的基礎材料,決定著機床未來的使用情況與壽命情況。現在使用的機床鑄件多為消震性較好,硬度和抗拉強度之間的關系也是 的復合科學原理。作為比較好的機床鑄件典范—泊頭正創機械有限公司做的較好些,為我們的好機床鋪了一條好路 。
眾所周知熱(re)處(chu)理(li)(li)作為鑄(zhu)(zhu)造業重(zhong)要的(de)(de)(de)(de)一項工作,深受很(hen)多(duo)買(mai)家的(de)(de)(de)(de)重(zhong)視,因為熱(re)處(chu)理(li)(li)的(de)(de)(de)(de)好壞(huai)決(jue)定著鑄(zhu)(zhu)件的(de)(de)(de)(de)總(zong)體質量。這道可(ke)以總(zong)體提高鑄(zhu)(zhu)材質量并賦予其不(bu)同性能工序,是許(xu)多(duo)買(mai)家都很(hen)看重(zhong)的(de)(de)(de)(de)一個(ge)步(bu)驟(zou),這也是取(qu)決(jue)日后此鑄(zhu)(zhu)材的(de)(de)(de)(de)適用范圍的(de)(de)(de)(de)一個(ge)過(guo)程(cheng)。熱(re)處(chu)理(li)(li)的(de)(de)(de)(de)主要過(guo)程(cheng)是通過(guo)對鑄(zhu)(zhu)材加熱(re)后冷卻時間(jian)的(de)(de)(de)(de)把握而進行的(de)(de)(de)(de),是一種(zhong)比較(jiao)(jiao)比較(jiao)(jiao)細的(de)(de)(de)(de)處(chu)理(li)(li)過(guo)程(cheng)。
作為(wei)機(ji)(ji)(ji)床(chuang)(chuang)的(de)基(ji)(ji)礎物件(jian)(jian)(jian),對于(yu)這種數(shu)控機(ji)(ji)(ji)床(chuang)(chuang)鑄件(jian)(jian)(jian)的(de)要求_有(you)(you)了(le)_要求,數(shu)控機(ji)(ji)(ji)床(chuang)(chuang)鑄件(jian)(jian)(jian)多為(wei)機(ji)(ji)(ji)床(chuang)(chuang)的(de)毛坯,是機(ji)(ji)(ji)床(chuang)(chuang)的(de)一種_的(de)材料。對于(yu)這種決定(ding)著(zhu)機(ji)(ji)(ji)床(chuang)(chuang)好(hao)(hao)壞的(de)鑄件(jian)(jian)(jian),也_是意味(wei)著(zhu)企業將來的(de)發展路線,只有(you)(you)好(hao)(hao)的(de)機(ji)(ji)(ji)器才(cai)(cai)能(neng)造出(chu)好(hao)(hao)的(de)零件(jian)(jian)(jian),才(cai)(cai)能(neng)造出(chu)_的(de)。這層關系_猶如蓋樓(lou)房一般,沒有(you)(you)好(hao)(hao)的(de)奠基(ji)(ji)怎么會有(you)(you)好(hao)(hao)的(de)樓(lou)層呢?
數控機床(chuang)鑄件作為機床(chuang)的(de)(de)一個重(zhong)要(yao)組(zu)成部分,它的(de)(de)形(xing)狀各(ge)式各(ge)樣,各(ge)不相同。為了(le)適(shi)應其(qi)機床(chuang)內部的(de)(de)復雜(za)結構(gou),機床(chuang)鑄件也會隨之(zhi)被鑄成各(ge)種復雜(za)的(de)(de)形(xing)狀。
機床鑄(zhu)件(jian)度注意的幾點(dian)事項(xiang)
一、為了_機床床身的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)度,粗(cu)加(jia)工(gong)(gong)(gong)(gong)(gong)和(he)加(jia)工(gong)(gong)(gong)(gong)(gong)_要(yao)分開。由于粗(cu)加(jia)工(gong)(gong)(gong)(gong)(gong)之時(shi),切削的(de)量很(hen)大,工(gong)(gong)(gong)(gong)(gong)件受到切削力、夾緊(jin)力都很(hen)大,發熱(re)量也是很(hen)多的(de),加(jia)工(gong)(gong)(gong)(gong)(gong)表面(mian)有明(ming)顯的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)硬化的(de)現象出現。對機床鑄件加(jia)工(gong)(gong)(gong)(gong)(gong)度要(yao)求很(hen)高。在粗(cu)加(jia)工(gong)(gong)(gong)(gong)(gong)后(hou)和(he)加(jia)工(gong)(gong)(gong)(gong)(gong)前(qian),還應該安排低(di)溫退(tui)火或(huo)者時(shi)效處理工(gong)(gong)(gong)(gong)(gong)序來消掉內應力。
二、合(he)理(li)(li)的(de)(de)(de)(de)選取設備。粗(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)要(yao)求(qiu)是切(qie)掉許多的(de)(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)剩余量,并且對于加(jia)(jia)(jia)工(gong)(gong)(gong)度(du)也(ye)是要(yao)求(qiu)并不(bu)太高的(de)(de)(de)(de),因(yin)此粗(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)應該在功率大、度(du)不(bu)是很高的(de)(de)(de)(de)機(ji)(ji)(ji)床上實行,加(jia)(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)序_是要(yao)求(qiu)用高度(du)的(de)(de)(de)(de)機(ji)(ji)(ji)床進(jin)行加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)(de)。機(ji)(ji)(ji)床鑄件(jian)粗(cu)、加(jia)(jia)(jia)工(gong)(gong)(gong)分(fen)別在不(bu)同的(de)(de)(de)(de)機(ji)(ji)(ji)床上進(jin)行深加(jia)(jia)(jia)工(gong)(gong)(gong),不(bu)僅(jin)能(neng)(neng)充(chong)分(fen)發揮設備的(de)(de)(de)(de)各(ge)種能(neng)(neng)力,又(you)能(neng)(neng)延長(chang)機(ji)(ji)(ji)床的(de)(de)(de)(de)周期。在機(ji)(ji)(ji)械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)(de)工(gong)(gong)(gong)藝當(dang)中,常(chang)常(chang)要(yao)有熱(re)處(chu)理(li)(li)的(de)(de)(de)(de)工(gong)(gong)(gong)序。熱(re)處(chu)理(li)(li)工(gong)(gong)(gong)序位置的(de)(de)(de)(de)安排(pai)如(ru)下:為了(le)提高金屬的(de)(de)(de)(de)切(qie)削加(jia)(jia)(jia)工(gong)(gong)(gong)性(xing)能(neng)(neng),一般安排(pai)我們(men)在機(ji)(ji)(ji)械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)之(zhi)前實行。為了(le)去掉內(nei)應力,例(li)(li)如(ru):時效處(chu)理(li)(li)、調質處(chu)理(li)(li)等等,一般安排(pai)在粗(cu)加(jia)(jia)(jia)工(gong)(gong)(gong)以(yi)后(hou),加(jia)(jia)(jia)工(gong)(gong)(gong)以(yi)前實行。為提升零件(jian)的(de)(de)(de)(de)機(ji)(ji)(ji)械(xie)(xie)性(xing)能(neng)(neng),例(li)(li)如(ru):滲碳、淬火、回火等等,一般安排(pai)在機(ji)(ji)(ji)械(xie)(xie)加(jia)(jia)(jia)工(gong)(gong)(gong)以(yi)后(hou)實行,例(li)(li)如(ru):熱(re)處(chu)理(li)(li)以(yi)后(hou)有比較大的(de)(de)(de)(de)變(bian)形,還需要(yao)安排(pai)_終加(jia)(jia)(jia)工(gong)(gong)(gong)的(de)(de)(de)(de)工(gong)(gong)(gong)序才能(neng)(neng)進(jin)行。
