摘要：

以小直径开缝套筒为研究对象，通过比较各种卷板机的成形特点，确定了双轴柔性滚弯技术作为小直径开缝套筒的成形方式。介绍了双轴柔性滚弯技术的成形原理，并在此基础上设计了一套制备小直径开缝套筒的伺服控制专用成形设备。对成形装备整机及上辊的应力变形情况进行了有限元分析。研究结果表明：整机最大应力发生在左后立柱与底座的螺栓联结部位，应力值为310.01 MPa，小于其屈服强度640 MPa；整机其他位置应力在84 MPa以下，变形较小，满足工作要求；上辊的最大应力值为83.086 MPa，远小于其屈服强度785 MPa，最大变形为0.16229 mm，变形较小，也满足刚度要求。

For a small-diameter split sleeve, the two-axle flexible roll-bending technique was determined by comparing the forming characteristics of various bending machines. Then, the forming principle of two-axle flexible roll-bending technique was introduced, and a set of servo control special forming equipment was designed based on the two-axle flexible roll-bending technique. Furthermore, the stress and deformation of the whole machine and the upper roller were analyzed by finite element method. The results show that the largest stress occurs on the bolt connection positions between the left rear column and base, which is 310.01 MPa and less than the yield strength of 640 MPa. The stress of other parts of the whole machine is less than 84 MPa and the deformation is small, which can meet working requirements. However, the maximum stress value of the upper roller is 83.086 MPa, which is much less than the yield strength of 785 MPa. And its maximum deformation is 0.16229 mm. The deformation is small so that it can also meet the requirements of stiffness.
