PURPOSE:To obtain a titled device for bending a work at a small bending interval by attaching a bending die and a bending arm to a bending shaft freely rotatably, providing a clamping die for clamping a work on the bending arm, and also connecting a driving link to said arm. CONSTITUTION:A pressure die sliding base 11 and a clamping die sliding base 17 and slid to this side, one end of a work W is chucked 3, a bending position is determined by moving a base 4, the base 11 and the base 17 are inverted and slid, and the work W is clamped between a bending die 9 and a clamping die 19. Subsequently, a bending motor 24 is driven by a control motor 46, pins 37, 41 are rotated by a prescribed angle by turning a chain 36 and a shaft 31, and pins 38, 42 are turned synchronously with the pins 37, 41 through links 21, 45. As a result, the link 21 executes a parallel link motion, a pin 22 executes a circular- arcuate motion around a bending shaft 10, a bending arm 14 is turned, and the work W is bent by a radius of curvature R. In this way, a work is bent at a small bending interval, and a bending head becomes small-sized.
