Abstract
PURPOSE: To easily perform the bending work for the thin-walled pipe into a small bending radius, the pipe of high rigidity, etc., by applying the ultrasonic vibration to the mandrel or the bending die, at bending the pipe.
CONSTITUTION: At the stretch bending, etc., in which the pipe 5 is clamped by the bending form 1 and the clamp die 2, and is bent successively by the pressure die 3, the mandrel 4 and the bending form 1 while the pipe 5 is being turned round, the ultrasonic vibrator 6 is attached to the rear end of the mandrel 4 or the bending die. Hereby, the pipe 5 is bent while the ultrasonic vibration is being applied to the mandrel 4 or the bending die. According to the present method, the bending resistance is weakened so that the generation of cracks in the pipe can be prevented. Moreover, the use of the lubricant can be excluded.
