　南(nan)陽珩磨(mo)管(guan)(guan)油(you)缸管(guan)(guan)絎磨(mo)管(guan)(guan)　冷(leng)拔油(you)缸管(guan)(guan)的(de)(de)(de)特性(xing)(xing)(xing)(xing)(xing)： 　　1.較小(xiao)的(de)(de)(de)外徑(jing)。 　　2.精(jing)度(du)高(gao)(gao)，可做(zuo)小(xiao)批(pi)量生產(chan)(chan) 　　3.冷(leng)拔產(chan)(chan)品精(jing)度(du)高(gao)(gao)，表(biao)(biao)面(mian)(mian)(mian)質量好。 　　4.鋼管(guan)(guan)的(de)(de)(de)橫截面(mian)(mian)(mian)積比較復雜。 　　5.鋼管(guan)(guan)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)較好，金屬(shu)(shu)致(zhi)密。 　　冷(leng)拔油(you)缸管(guan)(guan)由于(yu)表(biao)(biao)層存在(zai)殘余壓(ya)(ya)應(ying)力(li)，有利于(yu)封閉表(biao)(biao)面(mian)(mian)(mian)微(wei)裂(lie)紋(wen)，阻礙沖蝕擴展。因此，可以(yi)提(ti)高(gao)(gao)絎縫管(guan)(guan)的(de)(de)(de)表(biao)(biao)面(mian)(mian)(mian)耐(nai)蝕性(xing)(xing)(xing)(xing)(xing)，延緩疲(pi)勞(lao)(lao)裂(lie)紋(wen)的(de)(de)(de)產(chan)(chan)生或擴展，從(cong)而提(ti)高(gao)(gao)絎縫管(guan)(guan)的(de)(de)(de)疲(pi)勞(lao)(lao)強(qiang)度(du)。通過滾(gun)(gun)壓(ya)(ya)成(cheng)形(xing)(xing)，在(zai)滾(gun)(gun)壓(ya)(ya)表(biao)(biao)面(mian)(mian)(mian)形(xing)(xing)成(cheng)冷(leng)加(jia)(jia)(jia)工(gong)(gong)硬(ying)(ying)化層，減少了(le)(le)磨(mo)削副(fu)接觸面(mian)(mian)(mian)的(de)(de)(de)彈塑(su)(su)性(xing)(xing)(xing)(xing)(xing)變(bian)(bian)形(xing)(xing)，提(ti)高(gao)(gao)了(le)(le)絎縫管(guan)(guan)內壁(bi)的(de)(de)(de)耐(nai)磨(mo)性(xing)(xing)(xing)(xing)(xing)，避免了(le)(le)磨(mo)削燒傷。軋制(zhi)后，表(biao)(biao)面(mian)(mian)(mian)粗糙度(du)的(de)(de)(de)降低(di)可以(yi)改(gai)善匹配性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)。軋制(zhi)是一種無屑(xie)加(jia)(jia)(jia)工(gong)(gong)，它利用(yong)(yong)金屬(shu)(shu)在(zai)室(shi)溫(wen)下(xia)的(de)(de)(de)塑(su)(su)性(xing)(xing)(xing)(xing)(xing)變(bian)(bian)形(xing)(xing)，使工(gong)(gong)件表(biao)(biao)面(mian)(mian)(mian)的(de)(de)(de)微(wei)小(xiao)不平整度(du)變(bian)(bian)平，從(cong)而改(gai)變(bian)(bian)工(gong)(gong)件的(de)(de)(de)表(biao)(biao)面(mian)(mian)(mian)結構(gou)、力(li)學(xue)性(xing)(xing)(xing)(xing)(xing)能(neng)(neng)、形(xing)(xing)狀和(he)(he)尺寸(cun)。因此，這種方法可以(yi)同(tong)時達到(dao)精(jing)加(jia)(jia)(jia)工(gong)(gong)和(he)(he)強(qiang)化兩個(ge)目的(de)(de)(de)，這是磨(mo)削所不能(neng)(neng)達到(dao)的(de)(de)(de)。無論采用(yong)(yong)何種加(jia)(jia)(jia)工(gong)(gong)方法，零件表(biao)(biao)面(mian)(mian)(mian)都會出(chu)現(xian)微(wei)小(xiao)的(de)(de)(de)不均勻的(de)(de)(de)刀痕，并且(qie)會出(chu)現(xian)錯(cuo)峰錯(cuo)谷。滾(gun)(gun)壓(ya)(ya)加(jia)(jia)(jia)工(gong)(gong)原理：利用(yong)(yong)金屬(shu)(shu)在(zai)室(shi)溫(wen)下(xia)的(de)(de)(de)冷(leng)塑(su)(su)性(xing)(xing)(xing)(xing)(xing)特點，通過滾(gun)(gun)壓(ya)(ya)工(gong)(gong)具對工(gong)(gong)件表(biao)(biao)面(mian)(mian)(mian)施(shi)加(jia)(jia)(jia)一定的(de)(de)(de)壓(ya)(ya)力(li)，使工(gong)(gong)件表(biao)(biao)面(mian)(mian)(mian)的(de)(de)(de)金屬(shu)(shu)產(chan)(chan)生塑(su)(su)性(xing)(xing)(xing)(xing)(xing)流動(dong)，填充(chong)原有的(de)(de)(de)殘余槽，降低(di)了(le)(le)工(gong)(gong)件的(de)(de)(de)表(biao)(biao)面(mian)(mian)(mian)粗糙度(du)。由于(yu)軋制(zhi)表(biao)(biao)面(mian)(mian)(mian)金屬(shu)(shu)的(de)(de)(de)塑(su)(su)性(xing)(xing)(xing)(xing)(xing)變(bian)(bian)形(xing)(xing)，表(biao)(biao)面(mian)(mian)(mian)組(zu)織冷(leng)硬(ying)(ying)化，晶粒變(bian)(bian)細，形(xing)(xing)成(cheng)致(zhi)密的(de)(de)(de)纖維(wei)狀，形(xing)(xing)成(cheng)殘余應(ying)力(li)層。提(ti)高(gao)(gao)了(le)(le)硬(ying)(ying)度(du)和(he)(he)強(qiang)度(du)，從(cong)而提(ti)高(gao)(gao)了(le)(le)工(gong)(gong)件表(biao)(biao)面(mian)(mian)(mian)的(de)(de)(de)耐(nai)磨(mo)性(xing)(xing)(xing)(xing)(xing)、耐(nai)腐蝕性(xing)(xing)(xing)(xing)(xing)和(he)(he)相容(rong)性(xing)(xing)(xing)(xing)(xing)。軋制(zhi)是一種無切削的(de)(de)(de)塑(su)(su)性(xing)(xing)(xing)(xing)(xing)加(jia)(jia)(jia)工(gong)(gong)方法。滾(gun)(gun)壓(ya)(ya)管(guan)(guan)
