Abstract
PURPOSE:To bend a pipe with good accuracy without generating a wrinkle by inserting the pipe to be worked between the driving forming roll and driven forming roll on which a semi-circular groove is provided on the outer periphery and advancing the bending roll of which U groove is provided on the outer periphery. CONSTITUTION:A driving roll 1 is provided with a semi-circular groove 2 on the outer periphery and a driven forming roll 3 is provided with the semi-circular groove 4 in the same dimension as of the semi-circular groove 2 on the outer periphery and opposed at the lower side of the driving roll 1 by abutting thereto. The bending roll 6 having the U groove 5 in the same width as of the semi-circular grooves 2, 4 is provided advanceably and retreatably to and from the driving roll 1 side on the outer periphery by locating at this driven forming roll 3 side. A pipe 7 is inserted between the driving forming roll 1 driven by a motor and driven forming roll 3, fed in by the driving of the forming roll 1 and after its stopping a bending roll 6 is advanced to the forming roll 1 to bend the pipe 7. Consequently the pipe can be subjected to bending with good accuracy without generating a wrinkle or sticking a foreign matter to the inner face.
