Abstract
PURPOSE: To simplify the change of sheet thickness and the adjustment of bending angle by providing a push member at the rear of a movable die, taking in or out the member and adjusting a advance rate of a movable die.
CONSTITUTION: A work 20 is put on a lower die 4, a work end is protruded by a prescribed length toward the movable die 5a and then a ram is dropped by driving a work holding cylinder and the neighborhood of the work end is held by an upper and a low die 3, 4. Then, a bending cylinder is driven to lift an elevating frame 6 and to make the edge of the movable die 5a hit the work. The work is bent with the edges of the upper and the lower piece as bending centers and further bent by right angle by the lift of the elevating frame 6. Bending can be conducted by moving a wedge member 12 to any angle between an abtuse angle and a sharp angle. The work can be bent to any angle by complicating a movement of the elevating frame 6 and a gradient of the movable die 5a.
