2、修正圓度，橢圓度可≤0.01mm。<br /> 3、提高表面硬度，使受力變形，硬度提高HV≥4°<br /> 4、加工后有殘余應力層,提高疲勞強度提高30%。<br /> 5、提高配合質(zhì)量，減少磨損，延長零件使用壽命，但零件的加工費用反而降低。 <br /> 珩磨管和無縫鋼管的區(qū)別 <br /> 1、無縫鋼管主要特點是無焊接縫，可承受較大的壓力。產(chǎn)品可以是很粗糙的鑄態(tài)或冷撥件。<br /> 2、絎磨管是近幾年出現(xiàn)的產(chǎn)品，主要是內(nèi)孔、外壁尺寸有嚴格的公差及粗糙度。<br /> 20號優(yōu)質(zhì)絎磨管是一種根據(jù)冷扎或冷拉解決后的精密加工的無縫鋼管;全名：冷扎或冷拉20號優(yōu)質(zhì)絎磨管。因為精密鋼管內(nèi)外壁無空氣氧化層、承擔髙壓無滲漏、高精密、高光滑度、冷拔不形變、擴口、擠扁無縫隙等優(yōu)勢，因此關鍵用于制造氣動式或液壓件的商品，如汽缸或液壓缸，全是用無縫鋼管。精密鋼管的成分有碳C、硅Si、錳Mn、硫S、磷P、鉻Cr。<br /> 絎磨管采用加工工藝油缸管采用滾壓加工，由于表面層留有表面殘余壓應力，有助于表面微小裂紋的封閉，阻礙侵蝕作用的擴展。從而提高表面抗腐蝕能力，并能延緩疲勞裂紋的產(chǎn)生或擴大，因而提高絎磨管疲勞強度。通過滾壓成型，滾壓表面形成一層冷作硬化層，減少了磨削副接觸表面的彈性和塑性變形，從而提高了絎磨管內(nèi)壁的耐磨性，同時避免了因磨削引起的燒傷。滾壓后，表面粗糙度值的減小，可提高配合性質(zhì)。</div><p><img

class="khcont">為了使珩磨管的生產(chǎn)效率更高，我們采取了新的生產(chǎn)工藝，通過強力研磨、自動化研磨的方式來生產(chǎn)。其中自動化研磨又包括使用電力或者超聲波的研磨方式來完成生產(chǎn)任務。好的生產(chǎn)工藝，對于生產(chǎn)效率的提高是必然的，近年來，我們使用以上幾種研磨方式來生產(chǎn)研磨管，獲得了很大成效，對于內(nèi)圓外圓的研磨已經(jīng)不再是問題，相信在我們不斷的努力中，一定能取得更好的工藝發(fā)展。<br /> 珩磨管的日常工作原理主要是通過砂帶上的沙粒產(chǎn)生一定的壓力，在一定轉(zhuǎn)速之下進行的表面研磨。通過砂帶的上下移動對工件的上下表面來回磨削，達到一定效果。當然在研磨過程中要不斷的加潤滑油，進行冷卻，以免影響工件表面加工質(zhì)量。這樣得到的工件只是粗加工的工件，想要更好精度的產(chǎn)品還需進行精加工處理。</div><p><img

class="khcont">國標深孔鏜珩磨管的普遍性能指標檢測什么是珩磨鋼管|珩磨管，珩磨管工藝是什么？珩磨的作用是提高工件的表面光潔度和耐磨度,重要的一點是耐磨,因為珩磨過的物體表面形成了一定角度的交叉網(wǎng)紋什,這些網(wǎng)紋里可以存留一定的油,起到潤滑的作用,減少磨檫,所以需要珩磨的工件通常是在汽車發(fā)動機缸體或缸套各種液壓油缸各種液壓閥體汽車連桿摩托車缸體等等類似的直線運動或轉(zhuǎn)動的需要減少磨檫延長壽命的物體.國標深孔鏜珩磨管的普遍性能指標檢測有：工作壓力、擠扁、彎曲、擴口試驗等。<br /> 1、液(水)壓試驗：被試鋼管內(nèi)灌進去一定壓力的水，保持壓力一定時間，沒有漏水情況。該試驗為高品質(zhì)監(jiān)測，多見于品如數(shù)檢查。<br /> 2、擠扁試驗：把國標深孔鏜珩磨管試樣置放二平板焊接夾具正中間，在焊接夾具間施力致間距超出規(guī)范數(shù)值，檢查試樣變形區(qū)無間隙、開裂等缺陷。<br /> 3、拉伸實驗：把國標深孔鏜珩磨管試樣置放彎曲試驗機上，按規(guī)范的彎芯半徑，彎曲到標準要求的角度后，彎曲位置表面無裂紋或開裂等缺陷。<br /> 4、擴口試驗：將國標深孔鏜珩磨管試樣置放臺表面，張嘴往上面，將按規(guī)范錐度選用的頂心嵌進鋼管中，直至試驗直徑擴口率超出規(guī)范后，試樣表面無裂紋或開裂等缺陷。</div><p><img

卡鍵結(jié)構(gòu)參數(shù)的確定原則<br /> 液壓缸活塞腔在壓力油作用下，液油壓力作用在缸蓋上并通過卡鍵傳到缸筒的缸壁。因此，卡鍵受到擠壓力和剪切力的作用，同時對卡鍵產(chǎn)生一扭矩從而使卡鍵產(chǎn)生扭轉(zhuǎn)變形?？ㄦI的扭轉(zhuǎn)變形與卡鍵的結(jié)構(gòu)參數(shù)h(卡鍵的截面高度)、d(卡鍵內(nèi)徑)、d2（卡鍵外徑）有關。所以應根據(jù)以上兩面的諸多因素，綜合考慮合理設計?？ㄦI高度h大小是影響卡鍵的抗扭剛度、接觸應力的關鍵參數(shù)，因此，卡鍵高度h應根據(jù)卡鍵的剪切強度條件，同時也應考慮卡鍵的扭轉(zhuǎn)變形而定，故h值可適當取大些。<br /> 卡鍵外徑d2影響扭轉(zhuǎn)剛度和缸體的外徑尺寸?？ㄦI內(nèi)徑d1與其扭轉(zhuǎn)剛度有關。一般情況下，應使卡鍵截面中心同缸體內(nèi)徑一致。<br /> 2.2 卡鍵的安裝<br /> 卡鍵加工成圓環(huán)形后，以120°剖切三等份。裝配時首先將缸蓋放入缸筒內(nèi)，可稍向里多推進一些，再分別將呈三等份的卡鍵置入缸筒的環(huán)形鍵槽內(nèi)，然后將缸蓋輕輕向外拉出直至靠全卡鍵下側(cè)面為止。后安裝壓環(huán)（或套環(huán)），并用螺栓緊固.</div><p></p><div id="6116116"
