style="text-indent:25px">碾環(huán)機碾鍛齒圈和齒輪毛坯的鍛造工藝主要有一下幾個工序：墩粗、拔長、沖孔、擴孔。自由鍛和碾環(huán)工藝的區(qū)別主要在擴孔這個工序上。自由鍛一般采用馬杠擴孔，碾環(huán)主要采用輾壓擴孔。自由鍛時碾環(huán)主要是采用馬杠碾環(huán)。馬杠碾環(huán)的應(yīng)力應(yīng)變情況近似拔長，與長軸拔長又有區(qū)別，它是環(huán)形坯料沿圓周方向的拔長，是局部加載，整體受力。馬杠擴孔時變形區(qū)金屬沿切向和寬度方向流動。馬杠碾環(huán)時變形區(qū)金屬主要沿切向流動，并增大內(nèi)、外徑。馬杠上碾環(huán)的鍛件一般壁較薄，故對外端變形區(qū)金屬切向流動的阻力遠(yuǎn)小寬度方向，馬杠與鍛件的接觸面呈弧形，有利于金屬沿切向流動。因此馬杠碾環(huán)時鍛件尺寸變化是壁厚減薄，內(nèi)、外徑擴大，寬度（高度）方向稍有增加。因此，馬杠上擴孔可以鍛制薄壁的鍛件。福州臥式輾環(huán)機碾環(huán)機保養(yǎng)：電機軸承每年要檢查一次并加注潤滑油，滑塊軸承和芯棍軸承需要每半年檢查一次。</p><div

style="text-indent:25px">碾環(huán)機分為閉式與開式碾環(huán)機。閉式碾環(huán)機，將加熱并沖有小孔的坯料套在芯輥上，靠碾壓輥的內(nèi)緣帶動坯料改變，實現(xiàn)料厚度的減薄和直徑的擴張。這種工藝辦法機關(guān)等的限度，已較少采取。開式碾環(huán)機，將加熱并沖有小孔坯料套在芯輥上，碾壓輥的外緣發(fā)起坯料竄改，完成坯料厚度的減薄與直徑縮減的軋制成形。輾環(huán)機工作時錐輥與熱態(tài)毛坯之間的相互作用力沿著軸向軋制機構(gòu)的機架上的導(dǎo)軌通過壓下油缸傳遞到軸向軋制機構(gòu)的機架上，并使錐輥、軸向軋制機架等發(fā)生變形。錐輥是輾環(huán)機的重要部件，環(huán)件的端面軋制質(zhì)量在很大程度上與軸向軋制機構(gòu)有關(guān)。軸向軋制機構(gòu)由壓下油缸平衡油缸兩個液壓缸驅(qū)動，其中壓下油缸提供軸向軋制力，平衡油缸主要用于平衡錐輥裝配體自身的重量，其行程由一個行程開關(guān)調(diào)節(jié)，控制液壓缸運動,軸向軋制機構(gòu)的機架上面左右側(cè)各設(shè)置一個導(dǎo)軌副，以限制錐輥裝配體Z軸方向上的旋轉(zhuǎn)的自由度，保證軸向軋制過程中軸向軋制力傳動的平穩(wěn)性。輾環(huán)機具有材料利用率高的優(yōu)點。</p><div

style="text-indent:25px">關(guān)于碾環(huán)機的一些性能介紹相信很多同行的朋友對此都比較關(guān)注，碾環(huán)機又叫擴孔機，現(xiàn)在就有山東擴孔機領(lǐng)導(dǎo)廠家的小編為大家簡單介紹一下擴孔機的性能。軋制能力強。加工成品外徑6300mm、重量20000kg的環(huán)件，預(yù)制坯料外徑2500mm以內(nèi)、單邊壁厚800mm、高度方向軋制量200mm以上，加熱環(huán)坯一次上機即可完成軋制。錐輥(軸向軋輥)國內(nèi)自家采用目前國際較先進的30度錐角設(shè)計結(jié)構(gòu)。有效減小模具磨損，發(fā)揮更大的軋制能力。自動化控制水平及軋制環(huán)件下機熱態(tài)精度等技術(shù)指標(biāo)，達到或部分超過本世紀(jì)初國際先進水平。軋制環(huán)件端面平整、精度高，可完全替代進口機型。全新三維優(yōu)化設(shè)計的機器結(jié)構(gòu)，更有利于機器軋制能力的發(fā)揮，機器使用、維護、更換模具等更為方便。機器關(guān)鍵部位采用進口元器件，極大地提高整機穩(wěn)定性與可靠性。福州臥式輾環(huán)機</p></p><br
