采(cai)用(yong)滾(gun)(gun)(gun)壓加(jia)工，由(you)于表面層(ceng)留有(you)表面殘余壓應(ying)力，有(you)助于表面微小(xiao)裂(lie)紋(wen)的(de)(de)封(feng)閉，阻礙侵蝕作(zuo)用(yong)的(de)(de)擴展。從(cong)而提高(gao)表面抗腐(fu)蝕能力，并能延緩疲勞裂(lie)紋(wen)的(de)(de)產生或(huo)擴大，因而提高(gao)缸筒(tong)疲勞強度(du)(du)。通過滾(gun)(gun)(gun)壓成型，滾(gun)(gun)(gun)壓表面形成一層(ceng)冷作(zuo)硬化(hua)層(ceng)，減(jian)少(shao)了(le)磨(mo)(mo)削副接觸表面的(de)(de)彈性(xing)和塑(su)性(xing)變形，從(cong)而提高(gao)了(le)缸筒(tong)內壁(bi)的(de)(de)耐磨(mo)(mo)性(xing)，同時(shi)避免了(le)因磨(mo)(mo)削引起的(de)(de)shao傷(shang)。滾(gun)(gun)(gun)壓后，表面粗糙(cao)度(du)(du)值的(de)(de)減(jian)小(xiao)，可提高(gao)配合性(xing)質。
油缸(gang)(gang)(gang)是(shi)工(gong)程(cheng)機械主(zhu)要部件，傳(chuan)統的加工(gong)方法是(shi)：拉(la)削(xue)缸(gang)(gang)(gang)體(ti)——精(jing)鏜缸(gang)(gang)(gang)體(ti)——磨(mo)削(xue)缸(gang)(gang)(gang)體(ti)。采用滾(gun)(gun)(gun)壓(ya)(ya)方法是(shi)：拉(la)削(xue)缸(gang)(gang)(gang)體(ti)——精(jing)鏜缸(gang)(gang)(gang)體(ti)——滾(gun)(gun)(gun)壓(ya)(ya)缸(gang)(gang)(gang)體(ti)，工(gong)序是(shi)3部分，但時間上對比：磨(mo)削(xue)缸(gang)(gang)(gang)體(ti)1米大概在1-2天的時間，滾(gun)(gun)(gun)壓(ya)(ya)缸(gang)(gang)(gang)體(ti)1米大概在10-30分鐘的時間。投入對比：磨(mo)床或絎磨(mo)機（幾萬(wan)——幾百萬(wan)），滾(gun)(gun)(gun)壓(ya)(ya)刀（1仟——幾萬(wan)）。滾(gun)(gun)(gun)壓(ya)(ya)后，孔表面(mian)粗糙度由幢滾(gun)(gun)(gun)前Ra3.2～6.3um減(jian)小(xiao)為Ra0.4～0.8&um，
液壓缸(gang)結構(gou)基本(ben)上(shang)可以(yi)分為缸(gang)筒(tong)和(he)(he)缸(gang)蓋(gai)、活(huo)塞和(he)(he)活(huo)塞桿、密(mi)封(feng)裝置(zhi)、緩沖裝置(zhi)和(he)(he)排氣裝置(zhi)五(wu)個部分。今天威海力建小(xiao)編(bian)著(zhu)重(zhong)帶著(zhu)大家(jia)了解一下缸(gang)筒(tong)和(he)(he)缸(gang)蓋(gai)。
缸筒和缸蓋
一般來說，缸(gang)(gang)筒(tong)(tong)和(he)(he)(he)缸(gang)(gang)蓋的(de)結構(gou)(gou)形(xing)式(shi)(shi)和(he)(he)(he)其使(shi)用(yong)(yong)(yong)(yong)的(de)材(cai)料有關。工(gong)(gong)(gong)作壓力p＜10MPa時(shi)(shi)，使(shi)用(yong)(yong)(yong)(yong)鑄鐵；p＜20MPa時(shi)(shi)，使(shi)用(yong)(yong)(yong)(yong)無縫(feng)鋼管；p＞20MPa時(shi)(shi)，使(shi)用(yong)(yong)(yong)(yong)鑄鋼或鍛鋼。法蘭(lan)連(lian)接(jie)式(shi)(shi)，結構(gou)(gou)簡(jian)單，容易加(jia)(jia)(jia)工(gong)(gong)(gong)，也容易裝(zhuang)拆(chai)，但(dan)外(wai)形(xing)尺(chi)寸(cun)和(he)(he)(he)重(zhong)量(liang)(liang)都較(jiao)大(da)(da)，常用(yong)(yong)(yong)(yong)于鑄鐵制的(de)缸(gang)(gang)筒(tong)(tong)上(shang)。半環(huan)連(lian)接(jie)式(shi)(shi)，它(ta)(ta)的(de)缸(gang)(gang)筒(tong)(tong)壁(bi)部因開了(le)環(huan)形(xing)槽而(er)削弱(ruo)了(le)強度(du)，為此有時(shi)(shi)要(yao)(yao)加(jia)(jia)(jia)厚缸(gang)(gang)壁(bi)，它(ta)(ta)容易加(jia)(jia)(jia)工(gong)(gong)(gong)和(he)(he)(he)裝(zhuang)拆(chai)，重(zhong)量(liang)(liang)較(jiao)輕，常用(yong)(yong)(yong)(yong)于無縫(feng)鋼管或鍛鋼制的(de)缸(gang)(gang)筒(tong)(tong)上(shang)。螺紋連(lian)接(jie)式(shi)(shi)，它(ta)(ta)的(de)缸(gang)(gang)筒(tong)(tong)端部結構(gou)(gou)復雜，外(wai)徑加(jia)(jia)(jia)工(gong)(gong)(gong)時(shi)(shi)要(yao)(yao)求保證內(nei)(nei)外(wai)徑同心，裝(zhuang)拆(chai)要(yao)(yao)使(shi)用(yong)(yong)(yong)(yong)工(gong)(gong)(gong)具，它(ta)(ta)的(de)外(wai)形(xing)尺(chi)寸(cun)和(he)(he)(he)重(zhong)量(liang)(liang)都較(jiao)小(xiao)，常用(yong)(yong)(yong)(yong)于無縫(feng)鋼管或鑄鋼制的(de)缸(gang)(gang)筒(tong)(tong)上(shang)。拉桿連(lian)接(jie)式(shi)(shi)，結構(gou)(gou)的(de)通用(yong)(yong)(yong)(yong)性大(da)(da)，容易加(jia)(jia)(jia)工(gong)(gong)(gong)和(he)(he)(he)裝(zhuang)拆(chai)，但(dan)外(wai)形(xing)尺(chi)寸(cun)較(jiao)大(da)(da)，且較(jiao)重(zhong)。焊接(jie)連(lian)接(jie)式(shi)(shi)，結構(gou)(gou)簡(jian)單，尺(chi)寸(cun)小(xiao)，但(dan)缸(gang)(gang)底處內(nei)(nei)徑不(bu)易加(jia)(jia)(jia)工(gong)(gong)(gong)，且可(ke)能引(yin)起變形(xing)。
