イプの曲げ装置。 A first groove having a grooved portion whose cross section is approximately half the cross section of the pipe on the outer periphery, parallel to the outer peripheral edge on one side side with the center sandwiched therebetween, and in contact with the bottom of the grooved portion.
and a circular fixed roller having a second notch-like part, and a notch-like part of the fixed roller having a grooved part whose cross section is approximately half the cross section of the pipe on the outer periphery, and a notch-like part on the outer periphery of one side. A circular movable roller having one or two notches similar to the above is connected to the fixed roller so that the movable roller rolls while circumscribing the fixed roller. The cutout portion of the movable roller is fixed at the end position of pipe machining, where the movable roller is rotated 180 degrees around the fixed roller to form a pipe insertion hole with the shaped portion facing the second cutout portion of the fixed roller. A pipe bending device comprising: a connecting mechanism that forms a pipe removal hole facing a first notch-shaped portion of a roller.
