Abstract
PURPOSE: To obtain a small-sized lightweight bender by attaching an oil pressure cylinder to one of two rotating body pivoted to a central pin and attaching its ram to another and installing a pipe supporting mold to both sides of the central pin allowing free rotation.
CONSTITUTION: A pipe 17 is brought into contact with a flexible bending mold 10, and supporting molds 12, 14 are connected to the outer periphery of the pipe 17 and mounted to rotating bodies 1, 2 with pins 11, 15. When a ram 5c is extended by an oil pressure cylinder 5, force F and its reaction force are applied to the rotating bodies 2, 1 and they rotate clockwise and cointerclockwise respectively around the central pin 9 by angle θ. By this way, the pin 17 is bent to the position of pipe 17' while being supported by a mold 10. At this time, the central part of the pipe 17 is pushed up by force P and the both ends are pulled down by force Q and becomes P=2Q≥2F. The capacity of the oil pressure cylinder is less than a half that of a jim-crow bender. Buckling and becoming ellipse of bending compression side of the pipe 17 can be prevented surely by the mold 10.
