柳州45號珩磨管性能可靠 <柳州>九冶管業有限公司

為了提率(lv)，珩(heng)(heng)(heng)磨(mo)(mo)(mo)管(guan)的(de)生產都是機械化方式了，將珩(heng)(heng)(heng)磨(mo)(mo)(mo)頭(tou)與機床(chuang)主軸采用(yong)(yong)浮動(dong)連接(jie)，以(yi)保證余量(liang)均勻。由于砂(sha)條很長，珩(heng)(heng)(heng)磨(mo)(mo)(mo)時工(gong)(gong)件的(de)凸(tu)出部(bu)(bu)分先與砂(sha)條接(jie)觸(chu)，接(jie)觸(chu)壓力較大，使(shi)凸(tu)出部(bu)(bu)分很快被磨(mo)(mo)(mo)去，直至修(xiu)正(zheng)到工(gong)(gong)件表面(mian)與砂(sha)條全部(bu)(bu)接(jie)觸(chu)。因此(ci)，珩(heng)(heng)(heng)磨(mo)(mo)(mo)能夠修(xiu)正(zheng)前道工(gong)(gong)序產生的(de)幾(ji)何(he)形(xing)狀誤差和表面(mian)波度誤，但不能修(xiu)正(zheng)軸線位(wei)置誤差。要想使(shi)珩(heng)(heng)(heng)磨(mo)(mo)(mo)管(guan)獲得良好的(de)珩(heng)(heng)(heng)磨(mo)(mo)(mo)效果，除選用(yong)(yong)先進的(de)珩(heng)(heng)(heng)磨(mo)(mo)(mo)工(gong)(gong)具及正(zheng)確選用(yong)(yong)磨(mo)(mo)(mo)條材料(liao)和粒度外，珩(heng)(heng)(heng)磨(mo)(mo)(mo)時采用(yong)(yong)工(gong)(gong)藝參數(shu)對加工(gong)(gong)質量(liang)和生產率(lv)也有很大的(de)影響。比如說適當增加珩(heng)(heng)(heng)磨(mo)(mo)(mo)的(de)往復(fu)運動(dong)速度，除了提高工(gong)(gong)效外，還能改善表面(mian)質量(liang)。

珩(heng)(heng)磨(mo)(mo)管(guan)(guan)是選用(yong)(yong)精密(mi)(mi)無(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)制造機(ji)械(xie)結(jie)構或液壓設備等，精密(mi)(mi)鋼(gang)管(guan)(guan)通過冷拔(ba)或冷軋處理后的(de)(de)(de)(de)一種高(gao)(gao)精密(mi)(mi)的(de)(de)(de)(de)無(wu)縫(feng)(feng)鋼(gang)管(guan)(guan)。由于(yu)珩(heng)(heng)磨(mo)(mo)管(guan)(guan)內外壁無(wu)氧化(hua)層(ceng)、承受高(gao)(gao)壓無(wu)泄漏、高(gao)(gao)精度(du)、高(gao)(gao)光潔度(du)、冷彎不(bu)變形(xing)、擴(kuo)口(kou)、壓扁無(wu)裂縫(feng)(feng)等有(you)(you)點，所以主要(yao)用(yong)(yong)來生產氣(qi)(qi)動或液壓產品。珩(heng)(heng)磨(mo)(mo)管(guan)(guan)的(de)(de)(de)(de)敷(fu)設排列和走向應(ying)整齊一致(zhi)，層(ceng)次(ci)分(fen)明，盡量采用(yong)(yong)水平(ping)或垂(chui)直(zhi)(zhi)(zhi)布管(guan)(guan)，水平(ping)管(guan)(guan)道(dao)的(de)(de)(de)(de)不(bu)平(ping)行度(du)應(ying)≤2/1000；垂(chui)直(zhi)(zhi)(zhi)管(guan)(guan)道(dao)的(de)(de)(de)(de)不(bu)垂(chui)直(zhi)(zhi)(zhi)度(du)應(ying)≤2/400。用(yong)(yong)水平(ping)儀檢測。較長(chang)的(de)(de)(de)(de)管(guan)(guan)道(dao)必須(xu)考慮有(you)(you)效(xiao)措施以防止溫度(du)變化(hua)使管(guan)(guan)子(zi)伸(shen)縮而引起的(de)(de)(de)(de)應(ying)力。直(zhi)(zhi)(zhi)徑50mm以上的(de)(de)(de)(de)珩(heng)(heng)磨(mo)(mo)管(guan)(guan)一般應(ying)采用(yong)(yong)機(ji)械(xie)加(jia)工方法切割(ge)(ge)。如用(yong)(yong)氣(qi)(qi)割(ge)(ge)，則(ze)必須(xu)用(yong)(yong)機(ji)械(xie)加(jia)工方法車(che)(che)去(qu)因氣(qi)(qi)割(ge)(ge)形(xing)成的(de)(de)(de)(de)組織變化(hua)部分(fen)，同時可車(che)(che)出焊接(jie)坡口(kou)。除回(hui)油管(guan)(guan)外，壓力由管(guan)(guan)道(dao)不(bu)允(yun)許用(yong)(yong)滾輪式擠(ji)壓切割(ge)(ge)器切割(ge)(ge)，切割(ge)(ge)表面必須(xu)平(ping)整，去(qu)除毛刺、氧化(hua)皮、熔渣等。
