油缸即液壓缸,液壓缸是輸出力和活塞有效面積及其兩邊的壓差成正比的直線運(yùn)動(dòng)式執(zhí)行元件。它的職能是將液壓能轉(zhuǎn)換成機(jī)械能。液壓缸的輸入量是流體的流量和壓力,輸出的是直線運(yùn)動(dòng)速度和力。液壓缸的活塞能完成直線往復(fù)運(yùn)動(dòng),輸出的直線位移是有限的。液壓缸是將液壓能轉(zhuǎn)換為往復(fù)直線運(yùn)動(dòng)的機(jī)械能的能量轉(zhuǎn)換裝置。液壓缸基本上由缸筒和缸蓋、活塞和活塞桿、密封裝置、緩沖裝置與排氣裝置組成。緩沖裝置與排氣裝置視具體應(yīng)用場(chǎng)合而定,其他裝置則必不可少。
工作原理
液壓油缸的工作原理,主要有五個(gè)部件。先說它的最基本5個(gè)部件:1-缸筒和缸蓋,2-活塞和活塞桿,3-密封裝置,4-緩沖裝置,5-排氣裝置。
每種缸的工作原理幾乎都是相似的,拿一個(gè)手動(dòng)千斤頂來說,千斤頂其實(shí)也就是個(gè)最簡(jiǎn)單的油缸了。通過手動(dòng)增壓稈(液壓手動(dòng)泵)使液壓油經(jīng)過一個(gè)單向閥進(jìn)入油缸,這時(shí)進(jìn)入油缸的液壓油因?yàn)閱蜗蜷y的原因不能再倒退回來,逼迫缸桿向上,然后再做功繼續(xù)使液壓油不斷進(jìn)入液壓缸,就這樣不斷上上升,要降的時(shí)候就打開液壓閥,使液壓油回到油箱,這個(gè)是最簡(jiǎn)單的工作原理,其他的都是在這個(gè)基礎(chǔ)上改進(jìn)的,氣缸跟油缸的原理基本相同。
2加工方式
滾壓加工( Trundle processing)
滾壓加工是一種無切削加工,在常溫下利用金屬的塑性變形,使工件表面的微觀不平度輾平從而達(dá)到改變表層結(jié)構(gòu)、機(jī)械特性、形狀和尺寸的目的。因此這種方法可同時(shí)達(dá)到光整加工及強(qiáng)化兩種目的,是磨削無法做到的。
無論用何種加工方法加工,在零件表面總會(huì)留下微細(xì)的凸凹不平的刀痕,出現(xiàn)交錯(cuò)起伏的峰谷現(xiàn)象,
滾壓加工原理:它是一種壓力光整加工,是利用金屬在常溫狀態(tài)的冷塑性特點(diǎn),利用滾壓工具對(duì)工件表面施加一定的壓力,使工件表層金屬產(chǎn)生塑性流動(dòng),填入到原始?xì)埩舻牡桶疾ü戎?,而達(dá)到工件表面粗糙值降低。由于被滾壓的表層金屬塑性變形,使表層組織冷硬化和晶粒變細(xì),形成致密的纖維狀,并形成殘余應(yīng)力層,硬度和強(qiáng)度提高,從而改善了工件表面的耐磨性、耐蝕性和配合性。滾壓是一種無切削的塑性加工方法
無切削加工技術(shù)安全、方便,能精確控制精度,幾大優(yōu)點(diǎn)
1、提高表面粗糙度,粗糙度基本能達(dá)到Ra0.08μm左右
2、修正圓度,橢圓度可0.01mm。
3、提高表面硬度,使受力變形消除,硬度提高HV4
4、加工后有殘余應(yīng)力層,提高疲勞強(qiáng)度提高30%。
5、提高配合質(zhì)量,減少磨損,延長(zhǎng)零件使用壽命,但零件的加工費(fèi)用反而降低
