Abstract

PURPOSE: To bend the pipe along the outer surface of the round grooved plate into desired curvature, by employing plural round grooved plates of different radii and the hand operated ratchet mechanism.
CONSTITUTION: At first, a unit of bending plates 20, possessing the round grooved plate 2 provided with the groove size fittable to outer diameter of the pipe 3 and diameter equal to desired bending diameter, is set to the frame 14. Next, the pipe 3 is fitted to the bending plate 20 with the holding metal 9, and the right end of the pipe 3 is supported by the roller 10. Then the handle 19 is manually vertically swung watching the angle indicating needle 8 in order to turn the ratchet wheel 16 through the ratchet pawl 18; hereby, the bending plate 20 is turned together with the pipe 3. Hereupon, the pipe 3 is slid on the roller 10 and is formed into a circular arc along the curved plane of the round grooved plate 2, and is bent into the aim angle.
