style="font-size:36px;">中頻彎管機(jī)彎曲中心角的變化情況分析</span></p> <p align="left"> <span style="font-size:20px;">滄州奧程機(jī)械為客戶簡單介紹一下<a href="http:///">中頻彎管機(jī)</a>彎曲中心角較大時(shí)，管件尾部直線繼續(xù)被拉過切點(diǎn)B而彎曲變形時(shí)，由于纖維的制約作用，靠近切點(diǎn)B的直線段變形程度加大，而已成形的管件發(fā)生卸載，變形區(qū)從管前端向后轉(zhuǎn)移，因而消耗在管彎曲變形上的外載荷的增加將不再像彎曲中心角較小時(shí)那樣顯著。</span></p> <p align="left"> <span style="font-size:20px;">但是，彎曲中心角繼續(xù)增大時(shí)，已成形區(qū)的加工硬化效應(yīng)使得應(yīng)力在不低于已有水平上變化（否則管件將發(fā)生彈性恢復(fù)），而且為防止彎曲中管件發(fā)生彈性恢復(fù)，壓塊對(duì)管件施加更大的壓力，同時(shí)管件內(nèi)側(cè)壁厚的增加減小了芯棒與管件之間的間隙，管件直線段的移動(dòng)更為困難，從而增大了管件彎曲轉(zhuǎn)動(dòng)的阻力。另外柱形芯棒頭部不能彎曲，對(duì)彎曲段的支撐作用更加有限，這些因素的綜合作用將使得管截面承受的外載荷繼續(xù)增加，即便程度仍進(jìn)一步增大。</span></p>
