However, with the advancement of science and technology, there are more and more precision products, and people have higher and higher quality requirements for straight seam welded pipes used in precision products. In the production of straight seam welded pipes, it is usually necessary to first cooperate with auxiliary devices to complete the welding and forming, and then cool and remove the weld edges. However, the existing cooling devices and weld edge removal devices are either relatively fixed, which is complicated to adjust when producing welded pipes of different diameters, time-consuming and labor-intensive, making it difficult to quickly and flexibly respond to the production requirements of welded pipes with different diameters, or the structure is relatively complex, the equipment cost is high, and the burden on the enterprise is increased. Moreover, the traditional straight seam welded pipe is cooled by water spraying after welding. This cooling method consumes a large amount of cooling water, wastes a lot of water resources, and is costly. For this reason, people hope to find a device that can save water resources while ensuring cooling, and has a fast-adjustable, good adaptability, and low-cost online cooling and weld edge removal device for welded pipes.
