緩沖裝置
在液壓系統中使(shi)用液壓缸驅動具有(you)一定質量的機(ji)構，當液壓缸運動至行程(cheng)終點時具有(you)較大動能，如未作(zuo)減(jian)速(su)處(chu)理，液壓缸活塞與缸蓋將發生機(ji)械碰撞，產生沖(chong)擊、噪(zao)聲，有(you)破壞性。為(wei)緩(huan)和及防止這種危(wei)害發生，因(yin)此可(ke)在液壓回路(lu)中設置(zhi)減(jian)速(su)裝置(zhi)或(huo)在缸體(ti)內設緩(huan)沖(chong)裝置(zhi)。
加工
缸筒作為液壓(ya)缸、礦用單體支柱、液壓(ya)支架(jia)、炮(pao)管等(deng)產品的(de)主要(yao)部件(jian)，其加工(gong)(gong)(gong)質量(liang)的(de)好(hao)壞直接影(ying)響整個產品的(de)壽命和可靠性。缸筒加工(gong)(gong)(gong)要(yao)求高(gao)，其內(nei)表面粗(cu)糙度要(yao)求為Ra0.4～0.8&um，對同軸(zhou)度、耐磨(mo)性要(yao)求嚴格。缸筒的(de)基(ji)本特(te)征(zheng)是深孔加工(gong)(gong)(gong)，其加工(gong)(gong)(gong)一直困(kun)擾(rao)加工(gong)(gong)(gong)人(ren)員。
油缸(gang)(gang)是(shi)工(gong)程機械主要部件，傳統的加工(gong)方法(fa)是(shi)：拉削缸(gang)(gang)體(ti)(ti)(ti)(ti)——精鏜(tang)缸(gang)(gang)體(ti)(ti)(ti)(ti)——磨削缸(gang)(gang)體(ti)(ti)(ti)(ti)。采用滾壓方法(fa)是(shi)：拉削缸(gang)(gang)體(ti)(ti)(ti)(ti)——精鏜(tang)缸(gang)(gang)體(ti)(ti)(ti)(ti)——滾壓缸(gang)(gang)體(ti)(ti)(ti)(ti)，工(gong)序(xu)是(shi)3部分，但時間上對比(bi)：磨削缸(gang)(gang)體(ti)(ti)(ti)(ti)1米(mi)大(da)概在1-2天的時間，滾壓缸(gang)(gang)體(ti)(ti)(ti)(ti)1米(mi)大(da)概在10-30分鐘的時間。投入對比(bi)：磨床(chuang)或絎磨機（幾萬——幾百萬），滾壓刀(dao)（1仟——幾萬）。滾壓后(hou)，孔表面粗糙度由幢滾前Ra3.2～6.3um減小為(wei)Ra0.4～0.8&um，
液壓缸結(jie)構基(ji)本上可以分為缸筒(tong)和(he)(he)(he)缸蓋、活(huo)塞和(he)(he)(he)活(huo)塞桿、密(mi)封裝(zhuang)(zhuang)置(zhi)(zhi)、緩沖裝(zhuang)(zhuang)置(zhi)(zhi)和(he)(he)(he)排氣裝(zhuang)(zhuang)置(zhi)(zhi)五個部分。今天威海力建小編著重帶著大(da)家了解(jie)一下缸筒(tong)和(he)(he)(he)缸蓋。
缸筒和缸蓋(gai)
一般來說，缸筒(tong)(tong)(tong)和(he)缸蓋的(de)結(jie)(jie)構(gou)形(xing)式(shi)和(he)其使(shi)用(yong)(yong)(yong)的(de)材料有(you)關。工(gong)(gong)(gong)作(zuo)壓力p＜10MPa時，使(shi)用(yong)(yong)(yong)鑄鐵(tie)(tie)；p＜20MPa時，使(shi)用(yong)(yong)(yong)無縫鋼(gang)(gang)管(guan)；p＞20MPa時，使(shi)用(yong)(yong)(yong)鑄鋼(gang)(gang)或鍛(duan)鋼(gang)(gang)。法蘭連(lian)(lian)接(jie)式(shi)，結(jie)(jie)構(gou)簡單，容(rong)(rong)(rong)易(yi)加工(gong)(gong)(gong)，也(ye)容(rong)(rong)(rong)易(yi)裝(zhuang)拆(chai)，但外(wai)(wai)形(xing)尺(chi)寸(cun)和(he)重(zhong)量都較(jiao)大(da)，常用(yong)(yong)(yong)于(yu)鑄鐵(tie)(tie)制的(de)缸筒(tong)(tong)(tong)上(shang)。半環連(lian)(lian)接(jie)式(shi)，它的(de)缸筒(tong)(tong)(tong)壁(bi)部因開(kai)了環形(xing)槽而削弱了強度，為此(ci)有(you)時要(yao)加厚缸壁(bi)，它容(rong)(rong)(rong)易(yi)加工(gong)(gong)(gong)和(he)裝(zhuang)拆(chai)，重(zhong)量較(jiao)輕，常用(yong)(yong)(yong)于(yu)無縫鋼(gang)(gang)管(guan)或鍛(duan)鋼(gang)(gang)制的(de)缸筒(tong)(tong)(tong)上(shang)。螺紋連(lian)(lian)接(jie)式(shi)，它的(de)缸筒(tong)(tong)(tong)端部結(jie)(jie)構(gou)復雜，外(wai)(wai)徑(jing)(jing)(jing)加工(gong)(gong)(gong)時要(yao)求(qiu)保證內外(wai)(wai)徑(jing)(jing)(jing)同心，裝(zhuang)拆(chai)要(yao)使(shi)用(yong)(yong)(yong)工(gong)(gong)(gong)具，它的(de)外(wai)(wai)形(xing)尺(chi)寸(cun)和(he)重(zhong)量都較(jiao)小(xiao)(xiao)，常用(yong)(yong)(yong)于(yu)無縫鋼(gang)(gang)管(guan)或鑄鋼(gang)(gang)制的(de)缸筒(tong)(tong)(tong)上(shang)。拉桿(gan)連(lian)(lian)接(jie)式(shi)，結(jie)(jie)構(gou)的(de)通用(yong)(yong)(yong)性大(da)，容(rong)(rong)(rong)易(yi)加工(gong)(gong)(gong)和(he)裝(zhuang)拆(chai)，但外(wai)(wai)形(xing)尺(chi)寸(cun)較(jiao)大(da)，且較(jiao)重(zhong)。焊接(jie)連(lian)(lian)接(jie)式(shi)，結(jie)(jie)構(gou)簡單，尺(chi)寸(cun)小(xiao)(xiao)，但缸底(di)處內徑(jing)(jing)(jing)不(bu)易(yi)加工(gong)(gong)(gong)，且可(ke)能引(yin)起變形(xing)。
