The present invention relates to a pipe bending machine, in which a rotor is provided in a molding part installed on a top surface of a working table, a guide is slidably coupled to the rotor, a first rotation member is coupled to a rotation protrusion of the rotor, a second rotation member is installed in a rotation guide of the first rotation member, a motor is installed at a lateral side of the rotation guide, and the angles of the first and second rotation members are adjusted by the rotation protrusion and the motor, so that the angle of molding rollers of the second rotation member through which a pipe passes. Accordingly, the molding rollers are changed at various angles so that the pipe can ben bent in various shapes. According to the present invention, the angles of the molding rollers are freely adjusted by the first and second rotation members, so that the pipe can be bent in various shapes. The forming rollers are adjusted at various angles, so that the pipe having a complex shape can be easily formed. A single pipe can be bent at various angles in a work, so that the interference between the bent parts of the pipe does not occur, and the bending work is performed using a single device, thereby minimizing devices, improving a working efficiency, and saving labor cost. |
