CONTINUOUS BENDING DEVICE OF METAL PLATE AND ITS METHOD

PROBLEM TO BE SOLVED: To enable the bending of a metal plate at an acute angle, to enable continuous bending work and to enable suitable housing of the bent metal plate with a simple structure by providing a bending mechanism having a recessed blade edge and a projecting blade edge provided so as to freely abut and separated with a transfer mechanism in a metal plate sent out with a carrying mechanism. SOLUTION: When the continuous bending device 1 is operated, a prescribed length of the metal plate W is sent out of a pinch roll, an abutting and bending main body 5 is transferred with a transfer mechanism 7 and the other abutting and bending main body 4 is transferred with a transfer mechanism 6, and the metal plate W is bent with the projected blade edge 5a and the recessed blade edge 4b. Next, the abutting and bending main bodies 4, 5 are transferred in the separating direction with the transfer mechanisms 6, 7 and the abutting and bending main bodies 4, 5 are rotated to arrange the projecting blade edge 4a and the recessed blade edge 5b in the working position. Meanwhile, the metal plate W is sent by a prescribed length from the pinch roll of the carrying mechanism 2. The metal plate W is continuously bent by successively repeating the operation like this.
