      FESTO氣缸按活動(dòng)可分為哪幾種類別

  FESTO氣缸的內(nèi)徑巨細(xì)代表了氣缸輸著力的巨細(xì)?;钊诟淄矁?nèi)做安穩(wěn)的來去滑動(dòng),缸筒內(nèi)外面的外面粗糙度應(yīng)到達(dá)Ra0.8um。對(duì)鋼管缸筒,內(nèi)外面還應(yīng)鍍硬鉻,以減小摩擦阻力和磨損,并能避免銹蝕。缸筒材質(zhì)除應(yīng)用高碳鋼管外,照樣用高強(qiáng)度鋁合金和黃銅。小型氣缸有應(yīng)用不銹鋼管的。帶磁性開關(guān)的氣缸或在耐腐蝕情況中應(yīng)用的氣缸,缸筒應(yīng)應(yīng)用不銹鋼、鋁合金或黃銅等材質(zhì)。 FESTO氣缸活塞上采納組合密封圈完成雙向密封,活塞與活塞桿用壓鉚鏈接,不消螺母。

  FESTO氣缸的端蓋上設(shè)有進(jìn)排氣通口,有的還在端蓋內(nèi)設(shè)有緩沖機(jī)構(gòu)。桿側(cè)端蓋上設(shè)有密封圈和防塵圈,以避免從活塞桿處向外漏氣和避免外部塵土混入缸內(nèi)。桿側(cè)端蓋上設(shè)有導(dǎo)向套,以進(jìn)步氣缸的導(dǎo)向精度,蒙受活塞桿上大批的橫向負(fù)載,減小活塞桿伸出時(shí)的下彎量,延伸氣缸應(yīng)用壽命。導(dǎo)向套平日應(yīng)用燒結(jié)含油合金、前傾銅鑄件。端蓋曩昔罕用可鍛鑄鐵,為加重分量并防銹,常應(yīng)用鋁合金壓鑄,微型缸有應(yīng)用黃銅資料的。

  在FESTO氣缸有兩種類型:往復(fù)直線運(yùn)動(dòng)和往復(fù)擺動(dòng)。進(jìn)出直線的氣缸可分為四種:單影響、雙影響、隔膜式和沖擊式氣缸。

  (1)單作用缸:只有一端裝有活塞桿,從活塞一側(cè)供氣時(shí)產(chǎn)生氣壓,聚集能量,活塞被氣壓推出,靠彈簧或自重可以走。

  (2)雙作用氣缸:從活塞兩側(cè)供氣,單向或雙向傳力。

  (3)隔膜式氣缸:用隔膜代替活塞,只用一個(gè)偏壓力用彈簧復(fù)位。其密封功能好,但行程短。

  (4)沖擊氣缸:這是一種新型部件。

  它將壓縮氣體的壓力能轉(zhuǎn)化為活塞高速運(yùn)動(dòng)(10 ~ 20m/s)的動(dòng)能,從而做功。打擊筒上增加了帶噴嘴和排水口的中蓋。中蓋和活塞將氣缸分成三個(gè)室:儲(chǔ)氣室、頭室和尾室。廣泛用于切割、沖壓、開裂和成型。來回?cái)[動(dòng)的氣缸稱為擺動(dòng)氣缸。內(nèi)腔由葉片分成兩部分,氣體供給兩個(gè)腔。輸入軸擺動(dòng)角度小于280。其他還有反轉(zhuǎn)缸、氣液阻尼缸、步進(jìn)缸。

  (5)FESTO氣缸這是一種新型部件。它將壓縮氣體的壓力能轉(zhuǎn)化為活塞高速運(yùn)動(dòng)的動(dòng)能(10-20m/s),

  借以作功。打擊氣缸增加了帶有噴口和泄流口的中蓋。中蓋和活塞把氣缸分紅儲(chǔ)氣腔、頭腔和尾腔三室。它普遍用于下料、沖孔、破裂和成型等多種功課。作來去擺動(dòng)的氣缸稱擺動(dòng)氣缸,由葉片將內(nèi)腔分開為二,向兩腔瓜代供氣,輸入軸作擺動(dòng)活動(dòng),擺動(dòng)角小于 280°。別的,另有反轉(zhuǎn)展轉(zhuǎn)氣缸、氣液阻尼缸和步進(jìn)氣缸等。

  FESTO氣缸將緊縮空氣的壓力能轉(zhuǎn)換為機(jī)械能,驅(qū)動(dòng)機(jī)構(gòu)作直線來去活動(dòng)、擺動(dòng)和扭轉(zhuǎn)活動(dòng)。

  FESTO氣缸直線活動(dòng)來去活動(dòng)的氣缸、擺動(dòng)活動(dòng)的擺動(dòng)氣缸、氣爪等。

  FESTO氣缸是由缸筒、端蓋、活塞、活塞桿和密封件構(gòu)成:
