| 目的 借助有限元模拟对管材三辊行星旋轧的尺寸进行定量研究与分析。方法 采用三维扫描仪获得轧辊的宏观几何模型，采用Simufact.forming有限元软件，探究推进力、轧辊角度、自转速度及表面摩擦因数对TP2铜铸坯旋轧过程中变形和尺寸的影响。结果 通过扫描发现，轧辊的倾斜角和偏转角分别为50°和29°;模拟结果显示，采用剪切摩擦更适合管材尺寸的准确模拟，剪切摩擦因数最佳值为1.2;增大喂料小车推力有利于轧件三角形区域的增大，最佳推力为13 kN;此外，轧辊转速对轧件尺寸有一定影响，增大轧辊转速有利于扩径，最佳转速为160 r/min。结论 轧辊最低点位置和轧辊表面摩擦因数是影响轧件归圆后尺寸的2个关键因素，通过模拟研究可以准确获得管材的变形和几何参数。 |

| The work aims to quantitatively study and analyze the size of three-roll planetary rolling tubes through finite element simulation. The 3D scanner was used to obtain the macroscopic geometrical model of the roller. Meanwhile, the finite element software Simufact.forming was employed to investigate the effect of pulling force, rolling angles, rotational speed and surface friction coefficient on the deformation and size of the TP2 copper cast tube during rolling. The scanning result showed that the inclined angle and the deflection angle of the roller was 50° and 29°. The simulation results showed that the shear friction model was more suitable for accurate simulation of tube size and the optimal value was 1.2. Increasing the pulling force of the feeding trolley was beneficial to the increase of the triangular area of the rolled piece and the best value for the feeding trolley was 13 kN. In addition, the rotational speed of the roller had a certain effect on the size of the rolled piece. Increasing the rotational speed was beneficial to expanding the diameter, and the optimal speed was 160 r/min. In summary, the lowest position and the friction coefficient of the roller are the two key factors to affect the size of rolled piece after rounding. The deformation and the size of the tubes can be obtained by the method of finite element simulation. |
