REXROTH油缸(gang)采(cai)用滾(gun)(gun)壓加工，由(you)于(yu)表(biao)(biao)面(mian)(mian)層(ceng)留有(you)表(biao)(biao)面(mian)(mian)殘(can)余壓應力(li)，有(you)助于(yu)表(biao)(biao)面(mian)(mian)微小裂紋的封閉(bi)，阻礙侵蝕(shi)(shi)作用的擴展(zhan)。從(cong)而(er)提高表(biao)(biao)面(mian)(mian)抗腐(fu)蝕(shi)(shi)能力(li)，并能延緩疲勞裂紋的產(chan)生或擴大，因(yin)而(er)提高缸(gang)筒疲勞強度(du)。通過滾(gun)(gun)壓成(cheng)型，滾(gun)(gun)壓表(biao)(biao)面(mian)(mian)形成(cheng)一層(ceng)冷(leng)作硬化層(ceng)，減少(shao)了磨(mo)(mo)削(xue)副(fu)接觸表(biao)(biao)面(mian)(mian)的彈性(xing)(xing)(xing)和塑性(xing)(xing)(xing)變形，從(cong)而(er)提高了缸(gang)筒內(nei)壁(bi)的 性(xing)(xing)(xing)，同時避免了因(yin)磨(mo)(mo)削(xue)引起的滾(gun)(gun)壓后，表(biao)(biao)面(mian)(mian)粗糙(cao)度(du)值的減小，可(ke)提高配合(he)性(xing)(xing)(xing)質。滾(gun)(gun)壓原理及(ji)加工對(dui)比REXROTH油缸(gang)是(shi)一種無切削(xue)加工，在常溫下(xia)利(li)用金屬的塑性(xing)(xing)(xing)變形，使工件表(biao)(biao)面(mian)(mian)的微觀不平度(du)輾(zhan)平從(cong)而(er)達到改變表(biao)(biao)層(ceng)結構、機械(xie)特(te)性(xing)(xing)(xing)、形狀和尺寸的目的。因(yin)此(ci)這種方(fang)法(fa)可(ke)同時達到光整(zheng)加工及(ji)強化兩種目的，是(shi)磨(mo)(mo)削(xue)無法(fa)做(zuo)到的。

無論(lun)用何種加(jia)(jia)工(gong)方(fang)法加(jia)(jia)工(gong)，在零件(jian)表(biao)(biao)(biao)面(mian)總會(hui)留(liu)下(xia)微細(xi)的(de)(de)(de)(de)凸凹不平的(de)(de)(de)(de)刀痕(hen)，出(chu)現(xian)交錯起伏的(de)(de)(de)(de)峰(feng)谷(gu)現(xian)象，滾(gun)(gun)壓(ya)(ya)(ya)加(jia)(jia)工(gong)原理：它是一(yi)種壓(ya)(ya)(ya)力(li)光整(zheng)加(jia)(jia)工(gong)，是利用金屬(shu)(shu)在常溫狀(zhuang)態的(de)(de)(de)(de)冷(leng)塑(su)性特(te)點，利用滾(gun)(gun)壓(ya)(ya)(ya)工(gong)具對工(gong)件(jian)表(biao)(biao)(biao)面(mian)施(shi)加(jia)(jia)一(yi)定(ding)的(de)(de)(de)(de)壓(ya)(ya)(ya)力(li)，使工(gong)件(jian)表(biao)(biao)(biao)層(ceng)金屬(shu)(shu)產(chan)生塑(su)性流動，填入到原始殘留(liu)的(de)(de)(de)(de)低(di)凹波谷(gu)中，而達到工(gong)件(jian)表(biao)(biao)(biao)面(mian)粗糙值降低(di)。由(you)于(yu)被(bei)滾(gun)(gun)壓(ya)(ya)(ya)的(de)(de)(de)(de)表(biao)(biao)(biao)層(ceng)金屬(shu)(shu)塑(su)性變形(xing)，使表(biao)(biao)(biao)層(ceng)組織(zhi)冷(leng)硬化和晶粒(li)變細(xi)，形(xing)成(cheng)致(zhi)密(mi)的(de)(de)(de)(de)纖維(wei)狀(zhuang)，并形(xing)成(cheng)殘余應力(li)層(ceng)，硬度(du)和強度(du)提高(gao)，從而改善了(le)工(gong)件(jian)表(biao)(biao)(biao)面(mian)的(de)(de)(de)(de) 性、耐蝕(shi)性和配合性。滾(gun)(gun)壓(ya)(ya)(ya)是一(yi)種無切(qie)削的(de)(de)(de)(de)塑(su)性加(jia)(jia)工(gong)方(fang)法。REXROTH油(you)(you)缸(gang)(gang)要(yao)承受很大的(de)(de)(de)(de)壓(ya)(ya)(ya)強，負載越重，它的(de)(de)(de)(de)壓(ya)(ya)(ya)強就會(hui)越大，因此，做好非(fei)標油(you)(you)缸(gang)(gang)的(de)(de)(de)(de)保養(yang)工(gong)作是整(zheng)個液(ye)壓(ya)(ya)(ya)系統的(de)(de)(de)(de)維(wei)護 重要(yao)的(de)(de)(de)(de)一(yi)環。REXROTH油(you)(you)缸(gang)(gang)就相(xiang)當(dang)于(yu)液(ye)壓(ya)(ya)(ya)系統的(de)(de)(de)(de)心(xin)臟，心(xin)臟出(chu)問(wen)題很難(nan)修(xiu)補，所以液(ye)壓(ya)(ya)(ya)油(you)(you)缸(gang)(gang)的(de)(de)(de)(de)維(wei)護就是要(yao)謹慎細(xi)致(zhi)。

首先，要(yao)防銹。因(yin)(yin)為(wei)非(fei)標油(you)(you)(you)缸(gang)(gang)(gang)的(de)(de)活塞部(bu)分(fen)在(zai)工(gong)作(zuo)(zuo)(zuo)狀態中(zhong)(zhong)是(shi)(shi)要(yao)伸出油(you)(you)(you)缸(gang)(gang)(gang)的(de)(de)，自(zi)然就(jiu)(jiu)會(hui)受到氧化物的(de)(de)、酸性氣(qi)體的(de)(de)侵(qin)(qin)蝕(shi)，這(zhe)就(jiu)(jiu)需要(yao)我們給它涂敷適量(liang)的(de)(de)油(you)(you)(you)脂進行保護，以(yi)(yi)免作(zuo)(zuo)(zuo)為(wei)承重部(bu)件(jian)的(de)(de)活塞受侵(qin)(qin)蝕(shi)而在(zai)工(gong)作(zuo)(zuo)(zuo)中(zhong)(zhong)可(ke)能發生斷折。其次，要(yao)開箱(xiang)換油(you)(you)(you)。因(yin)(yin)為(wei)長(chang)時間(jian)使用(yong)(yong)(yong)，難免會(hui)有異物進入非(fei)標油(you)(you)(you)缸(gang)(gang)(gang)中(zhong)(zhong)，這(zhe)樣(yang)在(zai)使用(yong)(yong)(yong)中(zhong)(zhong)就(jiu)(jiu)會(hui)發生摩擦增大現象，另(ling)外，液(ye)(ye)壓(ya)油(you)(you)(you)也是(shi)(shi)有一(yi)定的(de)(de)使用(yong)(yong)(yong)壽命，長(chang)時間(jian)不換油(you)(you)(you)會(hui)損壞或者(zhe)侵(qin)(qin)蝕(shi)非(fei)標油(you)(you)(you)缸(gang)(gang)(gang)內部(bu)。治不如防，因(yin)(yin)此(ci)在(zai)REXROTH油(you)(you)(you)缸(gang)(gang)(gang)的(de)(de)工(gong)作(zuo)(zuo)(zuo)中(zhong)(zhong)要(yao)控制速(su)度適當，不要(yao)超過(guo)2m/s，這(zhe)樣(yang)可(ke)以(yi)(yi)延長(chang)液(ye)(ye)壓(ya)油(you)(you)(you)缸(gang)(gang)(gang)的(de)(de)使用(yong)(yong)(yong)壽命，另(ling)外為(wei)了保護機構和安(an)全起見(jian)，內部(bu)安(an)裝緩沖裝置對于(yu)(yu)非(fei)標油(you)(you)(you)缸(gang)(gang)(gang)的(de)(de)保護是(shi)(shi)十分(fen)1、由于(yu)(yu)氣(qi)動系統使用(yong)(yong)(yong)壓(ya)力(li)(li)一(yi)般在(zai)0.2-1.0Mpa范圍之內，因(yin)(yin)此(ci)氣(qi)缸(gang)(gang)(gang)是(shi)(shi)不能做為(wei)大功率的(de)(de)動力(li)(li)元件(jian)來(lai)使用(yong)(yong)(yong) REXROTH油(you)(you)(you)缸(gang)(gang)(gang)的(de)(de)，液(ye)(ye)壓(ya)缸(gang)(gang)(gang)就(jiu)(jiu)可(ke)以(yi)(yi)做比較大的(de)(de)功率的(de)(de)元件(jian)來(lai)使用(yong)(yong)(yong)，或者(zhe)使用(yong)(yong)(yong)油(you)(you)(you)缸(gang)(gang)(gang)系統。2、從介質講空氣(qi)是(shi)(shi)可(ke)以(yi)(yi)用(yong)(yong)(yong)之不竭的(de)(de)，沒(mei)有費用(yong)(yong)(yong)和供(gong)應(ying)方(fang)(fang)面的(de)(de)困難，將用(yong)(yong)(yong)過(guo)的(de)(de)氣(qi)體直接排入大氣(qi)，處理方(fang)(fang)便(bian)，不會(hui)污染(ran)液(ye)(ye)壓(ya)油(you)(you)(you)。3、空氣(qi)黏度小，阻力(li)(li)就(jiu)(jiu)小于(yu)(yu)液(ye)(ye)壓(ya)油(you)(you)(you)。

4、但因為(wei)空氣的(de)(de)(de)(de)壓(ya)(ya)(ya)縮(suo)率(lv)遠大(da)于液(ye)壓(ya)(ya)(ya)油，所以它的(de)(de)(de)(de)工(gong)作(zuo)平穩性(xing)(xing)和(he)(he)響(xiang)(xiang)應(ying)方面(mian)(mian)就(jiu)差好(hao)多了。油缸(gang)的(de)(de)(de)(de)加(jia)工(gong)　缸(gang)筒(tong)(tong)(tong)作(zuo)為(wei)油缸(gang)、礦(kuang)用(yong)單體支柱、液(ye)壓(ya)(ya)(ya)支架、炮管等(deng)產品的(de)(de)(de)(de)主要(yao)(yao)部件，其加(jia)工(gong)質(zhi)量的(de)(de)(de)(de)好(hao)壞直接影響(xiang)(xiang)整個(ge)產品的(de)(de)(de)(de)壽命和(he)(he)可靠性(xing)(xing)。缸(gang)筒(tong)(tong)(tong)加(jia)工(gong)要(yao)(yao)求高，其內表(biao)(biao)(biao)面(mian)(mian)粗糙度要(yao)(yao)求為(wei)Ra0.4～0.8?0?8m，對同(tong)(tong)軸(zhou)度 性(xing)(xing)要(yao)(yao)求嚴格。缸(gang)筒(tong)(tong)(tong)的(de)(de)(de)(de)基本特征(zheng)是深孔加(jia)工(gong)，其加(jia)工(gong)一直困擾加(jia)工(gong)人員。REXROTH油缸(gang)采用(yong)滾壓(ya)(ya)(ya)加(jia)工(gong)，由于表(biao)(biao)(biao)面(mian)(mian)層留有(you)表(biao)(biao)(biao)面(mian)(mian)殘余壓(ya)(ya)(ya)應(ying)力(li)，有(you)助于表(biao)(biao)(biao)面(mian)(mian)微(wei)小(xiao)裂紋(wen)的(de)(de)(de)(de)封閉，阻(zu)礙侵(qin)蝕作(zuo)用(yong)的(de)(de)(de)(de)擴(kuo)展(zhan)。從而(er)提高表(biao)(biao)(biao)面(mian)(mian)抗腐蝕能力(li)，并(bing)能延(yan)緩疲勞(lao)裂紋(wen)的(de)(de)(de)(de)產生或擴(kuo)大(da)，因而(er)提高缸(gang)筒(tong)(tong)(tong)疲勞(lao)強(qiang)度。通(tong)過(guo)滾壓(ya)(ya)(ya)成(cheng)型，滾壓(ya)(ya)(ya)表(biao)(biao)(biao)面(mian)(mian)形成(cheng)一層冷作(zuo)硬(ying)化層，減(jian)少了磨削(xue)副接觸表(biao)(biao)(biao)面(mian)(mian)的(de)(de)(de)(de)彈性(xing)(xing)和(he)(he)塑性(xing)(xing)變形，從而(er)提高了缸(gang)筒(tong)(tong)(tong)內壁的(de)(de)(de)(de) 性(xing)(xing)，同(tong)(tong)時避免(mian)了因磨削(xue)引起(qi)的(de)(de)(de)(de)滾壓(ya)(ya)(ya)后，表(biao)(biao)(biao)面(mian)(mian)粗糙度值(zhi)的(de)(de)(de)(de)減(jian)小(xiao)，可提高配合性(xing)(xing)質(zhi)。滾壓(ya)(ya)(ya)原理及加(jia)工(gong)對比

REXROTH油缸是一種(zhong)無切(qie)削(xue)加工，在常溫(wen)下利用金屬的塑性變(bian)(bian)形，使工件(jian)表面的微觀(guan)不平度輾平從而(er)達到(dao)改變(bian)(bian)表層結構、機械(xie)特性、形狀(zhuang)和尺寸(cun)的目的。
