It not only affects the appearance of the automobile but may also have practical functions such as noise reduction, deformation prevention, supercharging, and flow disturbance. Automobile tail decoration pipes are mainly made of stainless steel or galvanized materials.

[0003] With the lightweight design of automobiles, the automobile tail decoration pipe is required to reduce weight while ensuring its strength. The automobile tail decoration pipe is formed by stamping. During the stamping process, the stamping angle needs to be changed back and forth, which can more precisely control the shape and size of the product, obtain better material properties and surface quality, and thus improve the overall quality of the product. Currently, during the stamping process of the automobile tail decoration pipe, it is mainly through manual single-process operation, that is, for each stamping, manual material taking, flipping, and other operations are required once, resulting in low operation efficiency and waste of human and material resources.
