A device to level a metal plate fabricated from a material includes a frame, a leveling station, and a draw device. The leveling station includes a single upper roller and a pair of lower rollers in parallel arrangement and defining a serpentine path. A plunge depth is defined based upon a difference between a top-dead-center point of the lower rollers and a bottom-dead-center point of the single upper roller. A longitudinal spacing and the plunge depth are configured such that the single upper roller and the lower rollers are disposed to impart a bend radius on the metal plate as the metal plate is drawn or moved through the serpentine path such that the metal plate has line contact with the outer peripheral surfaces of the single upper roller and the lower rollers. The bend radius is selected to achieve plastification of the metal sheet.

Device and method for leveling a metal plate

A device to level a metal plate fabricated from high-strength steel material includes a frame, a leveling station and a draw device. The leveling station includes a plurality of upper and lower rollers in parallel arrangement and defining a serpentine path. A plunge depth is defined based upon a difference between a top-dead-center point of the lower rollers and a bottom-dead-center point of contiguous upper rollers. A longitudinal spacing and the plunge depth are configured such that the upper rollers and the lower rollers are disposed to impart a bend radius on the metal plate as the metal plate is drawn, via the draw device, through the serpentine path such that the metal plate conforms to the outer peripheral surfaces of the upper rollers and the lower rollers. The bend radius is selected to achieve plastification of the metal sheet.

A method uses a device to level a metal plate fabricated from high-strength metal material. The method includes providing a serpentine path between a plurality of upper and lower rollers in parallel arrangement to define a longitudinal spacing. The upper and lower rollers are positioned relative to one another such that a plunge depth is defined based upon a difference between a top-dead-center point of the lower rollers and a bottom-dead-center point of contiguous upper rollers, and a longitudinal spacing and the plunge depth are configured such that the upper rollers and the lower rollers are disposed to impart a bend radius on the metal plate as the metal plate is drawn through the serpentine path such that the metal plate bends about the outer peripheral surfaces of the upper and lower rollers. The bend radius is selected to achieve a desired plastification of the metal sheet.
