Abstract:
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.

Claim (Index 10):
A device configured to level a metal plate fabricated from high-strength steel material, the device comprising:\n a leveling station including a first and second upper roller and a first and second lower roller rotatably disposed on a frame in parallel arrangement in a lateral direction; wherein each of the first and second upper rollers includes an upper roller radius and a cylindrical outer peripheral surface that extends in the lateral direction and radially surrounds an upper axis of rotation; wherein each of the first and second lower rollers includes a lower roller radius and a cylindrical outer peripheral surface that extends in the lateral direction and radially surrounds a lower axis of rotation; wherein the upper axes of rotation are offset in the longitudinal direction from the lower axes of rotation such that an equidistant longitudinal spacing is defined between the axes of rotation of contiguous ones of the first and second upper and lower rollers; where the radii of each of the first and second upper rollers and the radii of each of the first and second lower rollers are equivalent; wherein a first plunge depth associated with the first upper roller and the first and second lower rollers is defined based upon a difference in an elevation direction between a top-dead-center point of the first and second lower rollers and a bottom-dead-center point of a contiguous one of the upper rollers; wherein a second plunge depth associated with the first and second upper rollers and the second lower roller is defined based upon a difference in the elevation direction between the top-dead-center point of the second lower roller and the bottom dead center point of the first and second upper rollers; wherein the magnitude of the first plunge depth is equal to the magnitude of the second plunge depth; wherein a serpentine path is defined between the outer peripheral surfaces of contiguous ones of the first and second upper rollers and the first and second lower rollers and is disposed in a longitudinal direction that is associated with a direction of travel for the metal plate; wherein the longitudinal spacing, the upper and lower roller radii, and the first and second plunge depths are configured such that the first and second upper rollers and the first and second lower rollers are disposed to impart first and second bend radii on the metal plate as the metal plate moves through the serpentine path as the metal plate bends about the outer peripheral surfaces of the first and second upper rollers and the first and second lower rollers to provide equal plastification on both sides of the metal plate; and wherein the first and second bend radii are equivalent and are selected to achieve greater than 90% plastification on opposing sides of the metal plate that is fabricated from high-strength steel after the metal plate moves along the serpentine path past the two upper rollers and the two lower rollers; and wherein there is a quantity of not more than the first and second upper rollers and a quantity of not more than the first and second lower rollers to achieve equal plastification on both sides of the metal plate.
