PURPOSE:To enable the bending of two kinds of radii and the bending in the right and left two directions by arranging to the device main body two kinds of bending dies having different diameters by dividing them into the upper ad lower and providing the pressure die which is successible and separable against the bending die. CONSTITUTION:The device main body 11 is possible in its horizontal action by a cross moving mechanism 12 and ascendable and descendable by a lift mechanism 13. A bending die 14 is composed of two kinds of dies having different diameters, fitted to the die opening and closing shaft 16 of the main body frame 15, being made openable and closable by a die opening and closing cylinder 17. On the device main body at both sides of the bending die 14, a pressure die 18 for the left bending and the pressure die 19 for the right bending are arranged, and each pressure die 18, 19 is ascendable and descendable respectively by pressure die lift mechanisms 20, 21 and yet accessible and separable respectively against the bending die 14 sliding mechanisms 22, 23.
