PURPOSE:To adjust and set automatically a curvature of a metallic die in a bending machine by interposing and providing a curvature adjusting device for adjusting a curvature of a metallic die, between a frame and the metallic die. CONSTITUTION:In a state that a punch 7 is matched with a die 3, when a wedge member 33 is moved and adjusted in the left and right directions, an intermediate plate 15 is adjusted finely in the upper and lower directions with respect to an upper frame 9. Accordingly, in plural curvature adjusting devices 13, a curve of the punch 7 can be set and adjusted to a suitable curvature as a whole by adjusting separately the wedge member 33. |
