<p>PROBLEM TO BE SOLVED: To provide a through feed correcting device for a bend blade in a bending machine for metal plates, the numbers of components of which are remarkably reduced but correction with which is accurate as to the driving device for the bend blade 3 which bending force is added to the metal plate W clamped to a lower die with an upper die. SOLUTION: Three or more of individual driving devices A1, A1 and A2 which are systematically controlled by a computer are arranged side by side so that a blade holder 9 is followed as the composition of the motion of the driving member 13 of a horizontal shaft with which horizontal force is mainly born and driving member 14 of a vertical shaft with which vertical force is mainly born. As for each individual driving device A1, A1 and A2, crank mechanisms 17 which are driven by respective independent servomotor 24 are provided for driving the driving member 13 of a horizontal shaft and the blade holder 9 is bent together with the bend blade 3 by the relativity of an independent position of each eccentric shafts 25, 25 and 25.</p> |
