Springback control method and device for rolling forming part

The invention discloses a springback control method and device for a rolling forming part, and belongs to the technical field of metal plastic working.The springback control method comprises the steps that rolling machining is conducted on the rolling forming part in the opposite direction; in the two side directions of the opposite direction, opposite lateral extrusion force is applied to the two sides of the rolling forming piece, so that the rolling forming piece generates plastic deformation in the two side directions; the springback control device comprises a support frame; the rolling assembly is connected to the supporting frame; and the extrusion assembly comprises an extrusion roller and a fastening piece, the extrusion roller is connected to the supporting frame, the extrusion roller can laterally move relative to the supporting frame so as to apply lateral extrusion force to the rolling forming piece, and the extrusion roller can be fixed to the supporting frame through the fastening piece.
