柔性滚压成形是一种将滚压成形与多点成形技术相结合的三维曲面零件成形新工艺。通过控制轧制过程中上下成型辊之间的差距分布，使板材在厚度方向上非均匀变薄，纵向延伸率沿着横向不同，使板材产生三维变形。本文通过测量模拟结果的形状误差，比较了不同板材的成形精度，板材材料为低碳钢08 Al板材和铝合金2024-O板材。对不同板材的环面和马鞍面零件进行了模拟，并给出了实验结果。仿真结果与实验结果吻合较好，验证了利用仿真指导实验的可行性。模拟结果的形状误差表明，08 Al板材的成形精度优于2024-O板材，但除成形部头尾区域外，其余各成形部在轧制方向上的偏差均小于2.0mm。
Flexible rolling is a novel forming process for three-dimensional surface parts combining the rolling process with multi-point forming technology. By controlling the distribution of the gap between the upper and lower forming rolls in the rolling process, the sheet metal is thinned non-uniformly in thickness direction, and the longitudinal elongation is different along the transverse direction, which makes the sheet metal generate three-dimensional deformation. In this paper, the comparison of the forming precision with different sheet materials is presented by measuring the shape errors of the simulation results, the materials of sheet metal are low carbon steel 08Al sheet and aluminum alloy 2024-O sheet. Torus and saddle surface parts of different sheet materials are simulated and their experimental results are presented. The simulated results are consistent with the experimental results which verify the feasibility of the use of simulation to guide the experiment. The shape errors of simulated results show that the forming precision of the 08Al sheet is better than that of the 2024-O sheet, but all the deviations of the forming parts are less than 2.0 mm excluding the head and tail regions of the forming parts in rolling direction.
