BENDING DEVICE

PROBLEM TO BE SOLVED: To improve the accuracy of products by preventing interference of a work with a work supporting table by fixing a drawing-in clamp in the right and left direction, making it freely movable in the vertical direction and setting it at the same height as the work supporting table. SOLUTION: By operating an elevating/lowering cylinder 23 and lowering the drawing-in clamp 17 through an elevating/lowering frame, the top plate 13 of the drawing-in clamp 17 is put in the same position as the work supporting table 20 and brought into contact with the pass line PL. The work W which is set on the origin by abutting on a pin gage 25 is clamped with the upper turret 7 and lower turret 8 of a manipulator 5, a side to be worked is selected by rotating it on the work supporting table 20, the work is conveyed in the Y-axis direction and positioned in the working position. The drawing-in clamp 17 is used as a part of the work supporting table 20. The work W is clamped with the top die 2 and bottom die 3 of a bending machine 1 and prescribed bending is executed with a bend beam 4.
