摘要：

斜辊矫直作为管材生产的最后一道工序，为达到薄壁细管严苛的精度要求，最优矫直工艺参数的设定至关重要。为解决薄壁细管矫直的难点,以现有的十辊矫直机为基础，设计了十辊薄壁细管矫直的模型，并进行了工艺参数研究。利用有限元软件ABAQUS建立了薄壁细管材矫直的有限元模型，通过分析不同条件下矫直后管材的X、Y方向的直线偏差、径向偏差得出了适合薄壁细管的最佳压弯量及压扁量，以此拟合出公式。根据公式计算了两组不同情况下管材的工艺参数，通过仿真模拟及实验验证了公式的可靠性，为薄壁细管精密矫直机的开发制造提供了理论依据。

Cross roll straightening is the final step in the production of steel pipes. To meet the stringent requirement on the quality of thin-walled tubes, optimal setting of process parameters is critical. In order to conquer the difficulties in straightening process, a model was established for a 10-roll straightening machine, and the process parameters were studied. Therefore, a 10-roll straightening model of thin-walled tube was established by finite element software ABAQUS, and the optimal bending and compressed values were obtained by analyzing the X, Y direction linear deviations and radial deviations of the tube under different conditions. Finally, a formula was fitted based on the optimal process parameters. Process parameters of tubes under two different conditions were calculated according to the formula, and then the reliability of the formula was verified through simulation and experiments, which lay a theoretical foundation of the manufacture of thin-walled tube fine straightening machine.
