Resumen:This study adopts the method combining experiments and numerical simulations to investigate the springback of roll forming. The forming force and hardness of each pass from 0° to 50° were measured, and the springback rate of each pass was calculated. The research results show that the change in hardness is similar to the change in springback rates. The work hardening phenomenon on the outside of the corner is larger than that on the inside of the corner. The springback phenomenon of the sheet metal under repeated overbending and rebending is analyzed through a numerical model. The springback decreases when the number of gradual approximation passes increases.
