Abstract：Applying the conventional straightening roller system in straightening the longitude profiled plate will severely reduce the straightening range and efficiency of the longitude profiled plate. In order to improve the thickness range and straightening quality of the longitude profiled plate，a longitude profiled plate straightening method based on a matching roller system method （large diameter straightening roller system and small diameter straightening roller system）was proposed. Firstly，the relationship between the roll diameter and the roll distance of the straightening machine based on the matching roller system was studied. The matching roller system of longitude profiled plate straightening machine was designed，the straightening technology of longitude profiled plate was proposed. Then，the partition principle of the longitude profiled plate with the matching roller straightening machine was studied. The finite element model of longitude profiled plate straightening process based on the matching roller system was established，and the simulation results were consistent with the measured results，which verified the correctness of the finite element model. Finally，the straightening process of the longitude profiled plate based on the matching roller system was simulated. The straightening force and residual stress of the longitude profiled plate under the conventional roller system and the matching roller system were calculated. The influence of different plate thickness partition on the straightening effect of the longitude profiled plate was analyzed. The results show that the designed matching roller system is suitable for the straightening of the longitude profiled plate and the straightening effect is better.
