Abstract：

Four-roll rolling is an advanced technology of sheet metal bending, but the problems of poor accuracy and low efficiency of rolling plate occur in the actual production due to lack of suitable technology, which restrictes the development of related industries greatly. The process of four-roll rolling was analyzed theoretically, the equation of plate springback was derived, and a mathematical model of rolling was established. Then, the whole plate rolling process was simulated by ABAQUS finite element analysis software, and the rolling radius of rolling cylinder was obtained. Furthermore, the differences among simulation radius, actual radius and theory radius were compared, and the reasons were analyzed. Finally, the feasibility of setting rolling process parameters by simulation analysis was verified, and high-precision products were obtained by adjusting the process parameters.
