Summary:In a long member bending apparatus having a bending head (2) and a material supply unit, the bending head (2) is composed of a base plate having a guide pipe (6), which includes a guide hole for passing a long member, at the center thereof, a movable plate having a die (8), which applies a bending force to the long member supplied from the guide pipe forward, disposed at the center thereof, and six extendable units (12) including hydraulic cylinders (10) interposed between the base plate and the movable plate and universal joints disposed to both the ends of each hydraulic cylinder, thereby a parallel link mechanism is arranged that executes a motion of a total of six degrees of freedom including three degrees of freedom of translational movement and three degrees of freedom of rotation by expanding and contracting the hydraulic cylinders to set the position (distance, offset), inclination, and the like of the movable plate with respect to the base plate.
