The invention relates to a pipe manufacturing machine for metal corrugated pipes. The pipe manufacturing machine comprises a machine base, a feeding and forming device and a side buckling device, wherein the feeding and forming device and the side buckling device are installed on the machine base; the side buckling device comprises a roller, a flange forming needle, a side buckling wheel, a printing wheel and an extruding wheel; according to the working sequence, the flange forming needle and the side buckling wheel are sequentially installed above the roller, the printing wheel is installed on one side of the roller, and the extruding wheel is installed on the other side of the roller; and a flange forming locating module is arranged at one end of the roller, the diameter of the flange forming locating module is slightly greater than the diameter of the roller, and a wheel opening of the side buckling wheel is located above the flange forming locating module. According to the technical scheme, the pipe manufacturing machine for the metal corrugated pipes has the advantages that debugging is easy, the flange forming effect and the side buckling effect are good, the manufacturing efficiency of the metal corrugated pipes is high, and the quality of the metal corrugated pipes is high.
