Abstract
PURPOSE: To reversely and efficiently fold the plate material without removing and reversing the plate material of the folding apparatus, by bending the plate upward and downward, and by transferring it progressively.
CONSTITUTION: When the work of a plate material which is clamped by a bottom die 9 and a top die 11, is bent to the prescribed angle by a bending die 15 of a bending beam 17, the bending beam 17 is rotated toward the side 1 of a work, and the rotating center is shifted toward the side 1 of the work. Next, the work is transferred and the rotating center of the bending beam 17 is moved to the bending position. Further, the bending beam 17 rotated toward another side bending the work reversely. Then, the rotating center of the bending beam 17 is moved to other side. Next, the work is transferred again from its bending position, as soon as the bending beam 17 is rotated, while bending the work reversely after shifting the center of the bending beam 17 to the bending position of the work.
