　　The bending and forming of sheet metal sheet metal in bending machine are carried out. The workpiece to be formed is placed on the bending machine. The brake shoe is lifted by lifting lever, the workpiece slides to the appropriate position, and then the brake shoe is lowered to the workpiece to be formed by applying force to the bending lever on the bending machine. Bending of cash.

　　The minimum bending radius is a function of ductility and thickness of formed metal. For aluminium sheet, the bending radius of the metal is larger than the thickness of the sheet. When bending, due to a certain rebound, the angle of metal bending is slightly larger than the required angle. The bending of sheet metal is carried out in the metal processing workshop.
