When the used ERW pipe tube mills is used to manufacture welded pipes. Rebound is generally not a very prominent issue. With the development of China's welded pipe industry, the application of various new materials in the welded pipe industry, the addition of various low-alloy and alloy steel welded pipes, stainless steel welded pipes and other metal elements, and the development and production of alloy welded pipes, they rebound during forming Has become a more prominent problem.
The forming springback is mainly manifested as:
(1)Design the forming roll according to the general pass design method, due to springback. The actual final shape is not the required shape. In particular, the edge of the strip is insufficiently formed.
(2) When the alloy welded pipe is produced at a higher speed, the rebound will cause cracks in the weld that has not completely solidified when leaving the squeeze roll, and cracks will appear on the inner surface of the welded pipe.
(3) In order to increase the welding speed of alloy welded pipe, it is required that the two edges of the pipe blank must be in close contact. The large springback causes the tube blank to open at the front and back edges of the squeeze roll, making welding impossible.
The forming of the welded pipe manufactured by the used ERW pipe tube mills is a plastic deformation process, which includes a part of elastic deformation, and it is the elastic deformation that causes the springback. Metal materials are not ideal plastic deformation materials. The work hardening phenomenon of metal materials and the complex deformation conditions during welded pipe forming make it difficult to obtain accurate solutions for springback.
As far as iron and steel materials are concerned, their elastic modulus is not very sensitive to small changes in chemical composition and changes in structure. Their elastic modulus is not much different, so their resilience mainly depends on the yield strength. so. The same is low-carbon steel, cold-rolled strip steel is stronger than hot-rolled strip steel, and the rebound is greater; low-alloy steel and alloy steel have higher strength than low-carbon steel, so the rebound is also greater.
The above are the main manifestations of springback when the used ERW pipe tube mills is used to manufacture welded pipes, which causes the quality of welded pipes to be insufficient.
