<p>PURPOSE: To simplify the attaching and detaching of a blade supporting member by connecting the blade supporting member to a pair of cylinders through a connecting plate. CONSTITUTION: A plate W is held with a counter blade 2 and a blank holder 3, and the plate W is bent by bending blades 14, 15. A blade supporting member 13 attached with bending blades 14, 15 is connected to a cylinder 21a via a connecting plate 20a. The connecting plate 20a is swung right and left by acting the cylinder 21a, advancing or retreating a piston rod 22a. The blade supporting member 13 is moved right and left around a horizontal pin 32a. The blade supporting member 13 is moved up and down around a pin 17a by acting a cylinder 30a. By controlling the action of the cylinders 21a, 30a, the positions of the bending blades 14, 15 are adjusted. The blade supporting member 13 can be detached only by releasing the connection of the connecting plate 20a and the blade supporting member 13.</p> |
