Abstract Wide and thick plate factories use movable head flattening presses, the reduction amount is basically determined by workers based on experience, and the straightening efficiency is low. In order to improve the working efficiency and straightening accuracy of the flattening machine, a multi-point flexible pressure straightening scheme and designs a multi-point flexible pressure straightening device for wide and thick plates was proposed. Using the elastoplastic theory, the calculation formula of the reduction is derived. Based on the finite element simulation method, the formula for calculating the amount of reverse bending was modified, and the correctness of the corrected straightening formula was verified by experiments. It lays a theoretical foundation for the subsequent research of multi-point flexible pressure straightening process.

Key words： wide and heavy plate flattening machine multi-point reverse bending reverse bending amount finite element simulation
