A bending machine, capable of accurately bending a workpiece to a desired angle while protecting the workpiece from damage, comprises an upper die fastened to a ram, which is movable vertically and acts in cooperation with a stationary table to fix a workpiece to be bent, a bending blade selection arm which can be vertically swung by a bending blade selection cylinder and to which a downward bending beam and an upward bending beam are fastened in such a manner that the downward bending beam and the upward bending beam are able to swing while being vertically separated from each other, a downward bending blade for bending the workpiece downwardly when the downward bending beam is swung by a downward blade swing cylinder, and an upward bending blade for bending the workpiece upwardly when the upward bending beam is swung by an upward bending blade swing cylinder. Therefore, the upward and the downward bending blades do not rub the workpiece.
