Abstract：

The plate with longitudinal rib is a shaped plate with complex structure, and the problems of insufficient metal filling in the groove and difficulty in forming ribs are more prominent in the rolling process. For the above problems, a new rolling process method for the plate with longitudinal rib was proposed to roll the plate with longitudinal rib by two passes. Then, the roller group of the first pass rolling was designed with a groove on the upper roller and an arc-shaped convex structure on the lower roller, and for the roller group of the second pass rolling, the upper roller was designed to have the groove with the same sizes as the first pass and the lower roller was designed as a flat roller. Therefore, this multi-pass rolling method could effectively promote the flow of metal into the upper roller groove and the growth of rib. Furthermore, the influences of roller structure on the rib height and the rib raised ratio as well as the forming limit of ribs with different plate thicknesses were analyzed by finite element simulation Abaqus, and the better forming process parameters were obtained. Finally, through experimental verification, the results show that the obtained simulation results are basically consistent with the experimental results to provide a theoretical basis for the subsequent precision forming research of shaped plates.
