摘要:

研究了四辊卷板机在弯卷工艺过程中材料的回弹问题。通过分析板件弯卷变形时受力状态与回弹曲率半径及弯卷半径之间的关系,建立了弯卷变形几何模型和计算模型,确立了弯卷力及弯矩的计算方法,并分析了影响最小弯卷半径的各因素。在对四辊卷板机上的预弯卷和弯卷过程进行受力分析的基础上,给出了弯曲功和驱动扭矩的计算方法。在电机功率、摩擦进给、接触应力和外层拉力等4个约束条件下分别提出了最小弯卷半径的计算方法。最后,用所建计算模型结合实际工艺参数计算最小弯卷半径并与实验值比较,计算结果与实际值比较吻合,验证了模型的有效性。

The springback of the material in the bending-rolling process was studied by four-roll bending-plate machine. Based on the relationship between stress state of bending plate with curvature radius of springback and bend radius, the models of geometric and calculation were set up. Then, calculation methods of bending force and bending moment were established, and four factors influencing on the minimum roll radius were analyzed. On the basis of force analysis for pre-bending and bending-rolling process on four-roller bend-plate machine, bending work and driving torque were given. The minimum curvature radius methods were put forward respectively under the four constraint conditions of the motor power, the friction feed, the contact stress and the outer sphere tension. Finally, the minimum curvature radius were calculated and compared with the experimental values by the calculation model combining with the practical technological parameters. The result shows that it is identical with the actual value, and the effectiveness of the models is verified.
