采用(yong)(yong)滾(gun)壓(ya)加(jia)工，由于(yu)表(biao)(biao)(biao)面(mian)(mian)層(ceng)留(liu)有(you)表(biao)(biao)(biao)面(mian)(mian)殘(can)余壓(ya)應力(li)，有(you)助于(yu)表(biao)(biao)(biao)面(mian)(mian)微小裂紋(wen)的(de)封閉，阻礙(ai)侵(qin)蝕作(zuo)(zuo)用(yong)(yong)的(de)擴展。從而(er)提高表(biao)(biao)(biao)面(mian)(mian)抗腐蝕能(neng)力(li)，并能(neng)延緩疲(pi)勞裂紋(wen)的(de)產生或擴大，因而(er)提高缸筒(tong)疲(pi)勞強度。通(tong)過滾(gun)壓(ya)成型，滾(gun)壓(ya)表(biao)(biao)(biao)面(mian)(mian)形成一層(ceng)冷作(zuo)(zuo)硬化層(ceng)，減(jian)(jian)少了(le)(le)磨削(xue)(xue)副接觸表(biao)(biao)(biao)面(mian)(mian)的(de)彈性和塑性變形，從而(er)提高了(le)(le)缸筒(tong)內壁的(de)耐(nai)磨性，同時避免了(le)(le)因磨削(xue)(xue)引起的(de)shao傷。滾(gun)壓(ya)后，表(biao)(biao)(biao)面(mian)(mian)粗糙度值(zhi)的(de)減(jian)(jian)小，可(ke)提高配合性質。
油(you)缸(gang)(gang)(gang)是(shi)工程機(ji)械主要部件，傳統的加工方法是(shi)：拉(la)削缸(gang)(gang)(gang)體(ti)(ti)——精鏜缸(gang)(gang)(gang)體(ti)(ti)——磨(mo)(mo)削缸(gang)(gang)(gang)體(ti)(ti)。采用(yong)滾(gun)壓(ya)(ya)方法是(shi)：拉(la)削缸(gang)(gang)(gang)體(ti)(ti)——精鏜缸(gang)(gang)(gang)體(ti)(ti)——滾(gun)壓(ya)(ya)缸(gang)(gang)(gang)體(ti)(ti)，工序(xu)是(shi)3部分，但時(shi)間上(shang)對(dui)比：磨(mo)(mo)削缸(gang)(gang)(gang)體(ti)(ti)1米大概(gai)在1-2天(tian)的時(shi)間，滾(gun)壓(ya)(ya)缸(gang)(gang)(gang)體(ti)(ti)1米大概(gai)在10-30分鐘的時(shi)間。投入對(dui)比：磨(mo)(mo)床(chuang)或(huo)絎磨(mo)(mo)機(ji)（幾(ji)萬(wan)——幾(ji)百萬(wan)），滾(gun)壓(ya)(ya)刀（1仟——幾(ji)萬(wan)）。滾(gun)壓(ya)(ya)后(hou)，孔表面(mian)粗糙度由幢滾(gun)前Ra3.2～6.3um減小為Ra0.4～0.8&um，
液壓缸(gang)結構(gou)基本上可以(yi)分(fen)為缸(gang)筒和(he)缸(gang)蓋、活(huo)(huo)塞(sai)和(he)活(huo)(huo)塞(sai)桿、密封裝(zhuang)(zhuang)置、緩沖裝(zhuang)(zhuang)置和(he)排氣裝(zhuang)(zhuang)置五個部分(fen)。今天(tian)威海力建小編(bian)著(zhu)重帶著(zhu)大(da)家了解一下缸(gang)筒和(he)缸(gang)蓋。
缸(gang)筒(tong)和缸(gang)蓋
一般來說，缸(gang)(gang)(gang)(gang)筒(tong)(tong)(tong)(tong)和缸(gang)(gang)(gang)(gang)蓋的(de)(de)結構形式(shi)(shi)和其使(shi)用(yong)(yong)的(de)(de)材料有(you)關(guan)。工(gong)(gong)(gong)作壓力p＜10MPa時，使(shi)用(yong)(yong)鑄(zhu)鐵(tie)；p＜20MPa時，使(shi)用(yong)(yong)無縫(feng)鋼(gang)管(guan)；p＞20MPa時，使(shi)用(yong)(yong)鑄(zhu)鋼(gang)或鍛鋼(gang)。法蘭連(lian)(lian)接(jie)(jie)式(shi)(shi)，結構簡(jian)單，容(rong)(rong)易(yi)加(jia)工(gong)(gong)(gong)，也容(rong)(rong)易(yi)裝(zhuang)拆(chai)，但(dan)外(wai)形尺寸和重量都(dou)較大(da)(da)，常(chang)用(yong)(yong)于(yu)鑄(zhu)鐵(tie)制(zhi)的(de)(de)缸(gang)(gang)(gang)(gang)筒(tong)(tong)(tong)(tong)上。半環(huan)連(lian)(lian)接(jie)(jie)式(shi)(shi)，它(ta)的(de)(de)缸(gang)(gang)(gang)(gang)筒(tong)(tong)(tong)(tong)壁部因開了(le)環(huan)形槽而削弱(ruo)了(le)強度，為此(ci)有(you)時要(yao)加(jia)厚缸(gang)(gang)(gang)(gang)壁，它(ta)容(rong)(rong)易(yi)加(jia)工(gong)(gong)(gong)和裝(zhuang)拆(chai)，重量較輕，常(chang)用(yong)(yong)于(yu)無縫(feng)鋼(gang)管(guan)或鍛鋼(gang)制(zhi)的(de)(de)缸(gang)(gang)(gang)(gang)筒(tong)(tong)(tong)(tong)上。螺紋連(lian)(lian)接(jie)(jie)式(shi)(shi)，它(ta)的(de)(de)缸(gang)(gang)(gang)(gang)筒(tong)(tong)(tong)(tong)端(duan)部結構復雜(za)，外(wai)徑(jing)加(jia)工(gong)(gong)(gong)時要(yao)求保證內外(wai)徑(jing)同心(xin)，裝(zhuang)拆(chai)要(yao)使(shi)用(yong)(yong)工(gong)(gong)(gong)具，它(ta)的(de)(de)外(wai)形尺寸和重量都(dou)較小(xiao)(xiao)，常(chang)用(yong)(yong)于(yu)無縫(feng)鋼(gang)管(guan)或鑄(zhu)鋼(gang)制(zhi)的(de)(de)缸(gang)(gang)(gang)(gang)筒(tong)(tong)(tong)(tong)上。拉桿(gan)連(lian)(lian)接(jie)(jie)式(shi)(shi)，結構的(de)(de)通用(yong)(yong)性大(da)(da)，容(rong)(rong)易(yi)加(jia)工(gong)(gong)(gong)和裝(zhuang)拆(chai)，但(dan)外(wai)形尺寸較大(da)(da)，且(qie)較重。焊接(jie)(jie)連(lian)(lian)接(jie)(jie)式(shi)(shi)，結構簡(jian)單，尺寸小(xiao)(xiao)，但(dan)缸(gang)(gang)(gang)(gang)底處內徑(jing)不易(yi)加(jia)工(gong)(gong)(gong)，且(qie)可能(neng)引起(qi)變形。
