活塞(sai)桿(gan)的(de)原(yuan)始(shi)表面(mian)質量（精車后）的(de)情況對滾(gun)(gun)壓(ya)質量有很大影響。當用剛性滾(gun)(gun)壓(ya)工(gong)(gong)(gong)(gong)(gong)(gong)具(ju)滾(gun)(gun)壓(ya)工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)時，滾(gun)(gun)壓(ya)精度主要取決(jue)于工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)原(yuan)始(shi)表面(mian)情況。一般剛性滾(gun)(gun)壓(ya)工(gong)(gong)(gong)(gong)(gong)(gong)具(ju)只(zhi)能(neng)提高原(yuan)始(shi)精度5%~10%左右。因此，工(gong)(gong)(gong)(gong)(gong)(gong)件(jian)滾(gun)(gun)壓(ya)前應(ying)達到圖(tu)紙要求的(de)幾(ji)何精度，表面(mian)粗糙度為Ra 6.3，原(yuan)始(shi)表面(mian)用寬刃刀光整加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)過(guo)為宜。 工(gong)(gong)(gong)(gong)(gong)(gong)藝規(gui)格(ge)設(she)計(ji)，及加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)過(guo)程(cheng)(cheng)中夾具(ju)的(de)設(she)計(ji)三個方面(mian)，闡述了(le)(le)組焊件(jian)活塞(sai)桿(gan)的(de)工(gong)(gong)(gong)(gong)(gong)(gong)藝制(zhi)(zhi)造的(de)全過(guo)程(cheng)(cheng)，尤其在工(gong)(gong)(gong)(gong)(gong)(gong)藝規(gui)程(cheng)(cheng)設(she)計(ji)中，我們運用已掌握的(de)機(ji)械(xie)制(zhi)(zhi)造理論(lun)及計(ji)算公式(shi)，確定(ding)了(le)(le)毛坯的(de)制(zhi)(zhi)造形(xing)式(shi)，選擇(ze)了(le)(le)基面(mian)，制(zhi)(zhi)定(ding)了(le)(le)工(gong)(gong)(gong)(gong)(gong)(gong)藝路線，確定(ding)了(le)(le)機(ji)械(xie)加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)余量、工(gong)(gong)(gong)(gong)(gong)(gong)序(xu)尺(chi)寸和毛坯尺(chi)寸，確定(ding)了(le)(le)切削用量及基本工(gong)(gong)(gong)(gong)(gong)(gong)時。

③倒角(jiao)系統采用原車床(chuang)尾(wei)座，抽(chou)去絲杠等(deng)(deng)內部零件，活塞桿廠家報(bao)價，加入鉆桿、電(dian)動(dong)機等(deng)(deng)改制(zhi)而成。倒角(jiao)電(dian)動(dong)機可(ke)實現變(bian)頻，調節轉速。當工件鉆孔結束，活塞桿廠家價格，工件在大(da)托板的帶動(dong)下快速返回進行倒角(jiao)。倒角(jiao)鉆桿莫氏錐度為(wei)6#，強度高。

活(huo)塞桿(gan)規格可以根據產(chan)品來(lai)訂的，而(er)活(huo)塞桿(gan)是(shi)現在機(ji)械行業中(zhong)運用較多的，而(er)它(ta)的加工難度比較大，那(nei)我們對它(ta)的特性要(yao)求硬度要(yao)高又要(yao)耐磨，東(dong)臺(tai)活(huo)塞桿(gan)，這樣對以后的產(chan)品有什么作用嗎(ma)?

活(huo)(huo)(huo)塞(sai)(sai)桿它(ta)主要由缸(gang)(gang)(gang)(gang)筒(tong)、活(huo)(huo)(huo)塞(sai)(sai)、缸(gang)(gang)(gang)(gang)蓋(gai)(gai)、缸(gang)(gang)(gang)(gang)底(di)、活(huo)(huo)(huo)塞(sai)(sai)桿頭及有關輔(fu)助裝置(zhi)(zhi)(zhi)等組成。活(huo)(huo)(huo)塞(sai)(sai)把缸(gang)(gang)(gang)(gang)簡分成左右兩腔，借(jie)助于(yu)壓力油的(de)(de)作(zuo)用(yong)，在(zai)(zai)缸(gang)(gang)(gang)(gang)筒(tong)內作(zuo)往復運(yun)動。為了(le)提高它(ta)的(de)(de)工作(zuo)效果(guo)，在(zai)(zai)活(huo)(huo)(huo)塞(sai)(sai)上(shang)沒有密(mi)封環以消除內部泄漏(lou)，在(zai)(zai)活(huo)(huo)(huo)塞(sai)(sai)桿通過缸(gang)(gang)(gang)(gang)蓋(gai)(gai)的(de)(de)地方，由于(yu)間隙(xi)的(de)(de)存在(zai)(zai)，容易產(chan)生(sheng)外漏(lou)現(xian)象，且灰塵可以經該間隙(xi)進入缸(gang)(gang)(gang)(gang)內，所(suo)以設置(zhi)(zhi)(zhi)了(le)密(mi)封裝置(zhi)(zhi)(zhi)和防塵因(yin)。同時為了(le)消除偏心(xin)載(zai)荷對活(huo)(huo)(huo)塞(sai)(sai)工作(zuo)的(de)(de)影響，所(suo)有的(de)(de)液壓缸(gang)(gang)(gang)(gang)都必須在(zai)(zai)活(huo)(huo)(huo)塞(sai)(sai)桿伸出端，設置(zhi)(zhi)(zhi)相當長度(du)的(de)(de)導向套(tao)。此外在(zai)(zai)活(huo)(huo)(huo)塞(sai)(sai)運(yun)動速(su)度(du)較快的(de)(de)情況下，活(huo)(huo)(huo)塞(sai)(sai)與缸(gang)(gang)(gang)(gang)底(di)和缸(gang)(gang)(gang)(gang)蓋(gai)(gai)產(chan)生(sheng)機械碰(peng)撞(zhuang)的(de)(de)現(xian)象嚴重，因(yin)此在(zai)(zai)液壓缸(gang)(gang)(gang)(gang)的(de)(de)兩端，應設置(zhi)(zhi)(zhi)緩沖減(jian)速(su)裝置(zhi)(zhi)(zhi)。
