The invention relates to the field of pipe manufacturing, in particular to a pipe manufacturing machine for metal bellows. The pipe manufacturing machine is mainly combined by squeezing devices, an edge buckle wheel and an edge buckle wheel supporting frame, wherein the edge buckle wheel is arranged at the top end of the edge buckle wheel supporting frame, the squeezing devices are connected with a shell of the pipe manufacturing machine, squeezing heads are arranged nearby the edge buckle wheel, and the gaps are not smaller than the thickness of a steel belt. According to the pipe manufacturing machine for the metal bellows, the double edge buckle wheel of an original pipe manufacturing machine is changed to a single edge buckle wheel structure and replaced by an edge forming needle with a sharpened end, the point end of the edge forming needle forms edges through squeezing the steel belt, so that the edge buckle of the metal bellows is easier, the difficulty in manufacturing and adjusting the metal bellows is greatly reduced, meanwhile, the pipe manufacturing efficiency is improved, and the quality of the metal bellows is further improved.
