Abstract
The invention belongs to the fields of metal processing methods and equipment therefor, and especially relates to a cold processing method of a metal sheet corner piece and a special metal sheet corner forming machine therefor. In an open slot bottom vertex angle position, a U-shaped metal plate is bended so that a bottom surface is perpendicular to a bended surface. Through an extrusion angulation system, an extrusion process is carried out simultaneously from the top, the bottom and two sides of a metal sheet corner piece, and the metal sheet corner piece is rolled so that the rolled metal sheet corner piece has three right angles on three surfaces. Through repeated rolling, the metal sheet corner piece is drawn thereby deforming slowly and metallographical arrangement is reformed so that the metal sheet corner piece does not crack, is fused into the integral body and has high strength. The cold processing method can avoid a welding line. The metal sheet corner piece treated by the cold processing method has high solidness, high strength, a smooth surface and no crack.
