The conveying module 200 conveys the pipe material, the pipe material passes through the cutting module 300, the roll-over stand 500 and the roll-over module 400, the distance adjusting module 600 drives the cutting module 300 to move according to the requirement of the length of the bent pipe, the distance between the cutting module 300 and the roll-over stand 500 is adjusted, and the cutting module 300 cuts the pipe material at a position meeting the requirement. Because the width of the cut pipe material breaking part is smaller, the roll-over stand 500 is directly driven to drive the pipe material to roll over so as to possibly collide with the components of the cutting module 300, and therefore, the distance adjusting module 600 drives the cutting module 300 to be far away from the roll-over stand 500, so that the roll-over stand 500 is driven to roll over by the roll-over module 400, and the pipe material can be stably bent to form a U-shaped pipe fitting. Therefore, the distance adjusting module 600 drives the cutting module 300 to move and adjust the distance between the cutting module 300 and the roll-over stand 500, the roll-over module 400 does not need to be stopped, the effect of adjusting the bending length of the U-shaped pipe fitting can be achieved, and the production operation is simplified, and the production efficiency is improved.
