The invention discloses a high-efficiency grinding-free automatic pipe making machine and a pipe making method. The pipe making machine includes a steel strip unwinding device, a steel strip flattening device, a steel strip hemming device, a steel strip closing device, and a closing welding device arranged in sequence. 1. Steel pipe shaping device and shaping and sizing device. The steel strip folding device presses the two side edges of the flattened steel strip into right-angled secondary bending edges. The steel strip closing device presses the steel strip to make the steel strip The two sides are gradually bent upwards and then closed, and the two sides of the steel belt of the closing welding device are welded to form a steel pipe. The pipe-making process adopted in the present invention gradually presses the two edges of the steel strip into a groove shape, and then closes the steel strip. After closing, the edges on both sides are located inside the groove body. When in use, the weld seam will be covered in the groove without affecting Use appearance. Therefore, the welding seam does not need to be polished, which can greatly improve the production efficiency and the problems caused by the welding seam grinding. There are no weld seams or grinding marks on the surface of the pipe, and the surface state can be easily smoothed to improve product quality.
