Plate Rolling

Plate rolling/plate bending, also known as three-roll bending, is a metalworking process used to form cylindrical or conical shapes from flat metal plates. Bending of plates uses work rolls to bend the sheet into shapes, which can form cylindrical parts, tapered parts and other parts of different shapes.

The working principle of bending plates is to move the work roll through the action of hydraulic pressure, mechanical force, and other external forces so that the sheet is bent or rolled into shape. In plate roll bending, the metal plate is placed between three rollers that are arranged in a pyramid shape. The two bottom rollers are fixed, while the top roller is adjustable and can be moved up or down to apply pressure to the metal plate. The plate is fed through the rollers and the top roller applies pressure to deform the metal and form it into a cylindrical or conical shape.

The rollers are designed with varying diameters to achieve different radii of curvature. The radius of curvature is determined by the distance between the center of the top roller and the centers of the two bottom rollers.

Bending of plates can process elliptical parts, arc-shaped parts, cylindrical parts, and other parts according to the rotation movement and position changes of work rolls of different shapes.

Plate roll bending is a versatile process that can be used to create a wide variety of shapes, including cylinders, cones, ellipses, and parabolas. It is commonly used in industries such as shipbuilding, aerospace, and construction for the production of pipes, tanks, and other curved structures.
