Abstract:
The purpose of the present invention is to provide a pipe bending apparatus comprising a turning means that can be easily implemented at low cost and can be used for bending pipes in different directions and in different shapes. In order to achieve this purpose, in the pipe bending apparatus of the present invention, a pipe feeding base (61) is disposed so as to be movable in the feeding direction of a pipe (P), a feeding means (60) is configured by rotatably disposing a chuck (63) on the feeding base to support the pipe, a cam (71) formed by bending a long plate or rod is disposed substantially parallel with the movement direction of the feeding base, a cam follower (86) is disposed on the feeding base so as to be movable in a direction perpendicular to the axis of the pipe, a turning means (70) is configured by engaging the cam follower with the cam and also connecting the cam follower to the chuck, and, together with an operation which moves the feeding base forward, the cam follower follows the cam and moves, and the motion of the cam follower is transmitted to the chuck so as to turn the chuck.
