1。手工修邊。操作者手持刀具，沿著產(chǎn)品的外緣，將溢邊逐步修去。這是較原始的方法。效率低、質(zhì)量難保證，特別對尺寸較小,精度要求高的O型圈難以做到徹底、于凈，而且很容易損及產(chǎn)品本體與溢邊的連接部。往往留下齒痕、缺口，從而留下漏油、漏氣等影響密封的后遺問題。另外。手工修邊對操作熟練程度的依賴也很突出。 2.機(jī)械修邊。為了提高效率和質(zhì)量，出現(xiàn)了機(jī)械修邊。常見的是帶旋轉(zhuǎn)刀刃的**電動修邊機(jī)。所用的刀刃需與制品尺寸高度匹配。如果產(chǎn)品的內(nèi)外緣都有溢邊。則可設(shè)計成雙刃、多刃口。以實現(xiàn)一次完成。機(jī)械修邊的加工精度超過手工修邊，效率也有成倍提高，特別對一模多腔的產(chǎn)品而言，可以按照產(chǎn)品的排列與分布，設(shè)計出與之匹配的刀具。待產(chǎn)品出模后。可整版套上，一次完成沖切。在加熱的配合下，一次能修幾十個。關(guān)鍵是沖切溫度必須掌握好，防止過高后粘連。黑龍江品質(zhì)橡膠密封件O型圈普遍用于多種機(jī)械設(shè)備中。</p><div

style="text-indent:25px">橡膠O型圈成品的脹大于縮短率動搖規(guī)模很大，橡膠O型圈海面成品通常選用一次或許二次硫化，初次發(fā)泡硫化（又成發(fā)孔）模具型腔按成品尺度減小60%擺布，第二次按成品尺度擴(kuò)大7%-10%作為定型硫化膠料縮短率是一個改變多端，極為雜亂的疑問，也是模具設(shè)計者較需求慎重考慮的疑問，當(dāng)前，還沒有一個真實的，完善的，具有實用價值的核算公式，還只能以憑借經(jīng)歷估計或許經(jīng)過積累實踐丈量數(shù)據(jù)作為參閱。由于即使是用一種膠料，同一幅模具，在同一技術(shù)條件下（如硫化溫度一樣，硫化壓力一樣，生料添入量也一樣）硫化，所得到的縮短率也不盡一樣因而以實驗測的成品的縮短率也是一個近似值，再加上遭到成品形狀，硬度，成型技術(shù)等因素的影響。</p><p style="text-indent:25px">因為不同的設(shè)備的作業(yè)環(huán)境不同，所需要的橡膠密封件的耐溫、耐油的條件也不同，而且每種產(chǎn)品因為形狀各異，因此在選擇密封件時需要另外設(shè)計。橡膠密封件的密封材料的性能是保證有效密封的重要因素，選擇密封材料，主要是根據(jù)密封元件的工作環(huán)境，如使用溫度、工作壓力、所使用的工作介質(zhì)以及運(yùn)動方式等。密封材料的基本要求如下： 1、具有一定的力學(xué)性能，如拉伸強(qiáng)度、伸長率等。 2、彈性和硬度適當(dāng)，壓縮長久變形小。 3、耐高溫和低溫，高溫下不分解、軟化，低溫下不硬化。 4、與工作介質(zhì)相適應(yīng)，不產(chǎn)生溶脹、分解、硬化等。 5、耐氧性和耐老化性好，經(jīng)久耐用。 6、耐磨損，不腐蝕金屬。 7易于成形加工，價格低廉。圓形橡膠密封件，一般為防漏使用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="黑龍江品質(zhì)橡膠密封件,橡膠密封件"

style="text-indent:25px">O形圈橡膠材料的硬度與工作壓力的關(guān)系在橡膠材料標(biāo)準(zhǔn)中，以硬度和壓縮長久變形兩項性能較為主重。選擇壓縮變形較小的橡膠材料對密封性能是有利的，而硬度對于O形橡膠密封圈耐壓和抗擠又是至關(guān)重要的。根據(jù)國內(nèi)標(biāo)準(zhǔn)和實踐經(jīng)驗，橡膠在規(guī)定溫度下的壓縮長久變形較大不超過50%。而橡膠的硬度與密封工作壓力密切相關(guān)，壓力越高，硬度也是越高; 橡膠O型圈模壓制品在硫化時，膠料會很快充滿整個模腔，因為填充的膠料需要一定的過盈量，這些多余的膠料就會沿著分模面流出，造成內(nèi)外徑不同厚度的膠邊。由于橡膠O型圈是需要嚴(yán)格控制質(zhì)量和外觀的，因為其功能為密封，小小的膠邊就有可能影響到整個密封性能，所以硫化后的成品還需要進(jìn)行修邊加工，要對這些多余的膠邊進(jìn)行去除工作，這個過程就叫做修邊。但是一般來說尺寸規(guī)格越小，構(gòu)型越復(fù)雜，難度越高，費(fèi)時耗工越多。橡膠密封件密封重點(diǎn)，例如決定活動點(diǎn)是在內(nèi)徑的拉桿封或活動點(diǎn)是在外徑的活塞封等。黑龍江品質(zhì)橡膠密封件</p><p style="text-indent:25px">O形橡膠密封圈的制作方法還是主要用過模壓法生產(chǎn)為主。黑龍江品質(zhì)橡膠密封件</p><p style="text-indent:25px">使橡膠密封件能發(fā)揮出好的性能與使用壽命： 1、首先使用前提是需要選擇合適的密封件材料和液壓油，以便橡膠密封件在工作運(yùn)作中對溫度的適應(yīng)性，與對油的相容性。 2、與橡膠密封件相對滑動的幾何位置精度高、材質(zhì)好和表面粗糙度較細(xì)可延長使用壽命。 3、對于液壓泵，安裝時還要用一個安裝套筒或薄墊片來保護(hù)密封件，以免唇邊翻卷、扭曲，導(dǎo)致彈簧滑出。 4、液壓缸內(nèi)要常用滾壓加工，這樣不但改善了表面的粗糙度，同時還可以做冷作硬化處理，有利于延長密封環(huán)的使用壽命；后續(xù)還需要根據(jù)壓力、滑動面的長度及種類，這些條件決定“定檢”時間。 5、橡膠密封件面要潤滑狀態(tài)良好、防止顆粒侵入；其次使用規(guī)定的油液和正確的安裝方法，是必要的條件。黑龍江品質(zhì)橡膠密封件</p><p>
