Bumps on the surface of aluminum tubes have always been an important cause of poor surface quality of aluminum tube cold-drawn products. However, during the production process of cold-drawn aluminum tubes, the aluminum tubes are often moved coldly, and surface bumps are the root cause of poor surface quality. Therefore, the production of high-quality aluminum tubes requires careful protection of the surface of the aluminum tubes during the production process. After the cold-drawing of the aluminum tubes is completed, the process of loading into the material bar is the most likely to cause damage to the surface of the aluminum tubes. For this process, a material moving device is designed to Reducing or eliminating surface bumps can effectively avoid the occurrence of poor surface of aluminum tubes.

At present, the method adopted by most domestic cold-drawn aluminum tube factories is that after cold-drawing, the aluminum tube directly falls on the chain or material column of the cold-drawing machine. The former collides with the chain and causes great damage. The occurrence of bumps reduces the quality of the aluminum tube, and the improvement of the material-moving technology during the cold-drawing process of the aluminum tube has become an important problem to be solved in the cold-drawing process of the aluminum tube.
