Description

Technical Field

[0001] The invention relates to the technical field of metal rolling, and in particular to an automatic metal strip rolling device. Background Art

[0002] Metal strip rolling is a metal processing process that processes metal raw materials into strips or other shapes. The rolling process is an important technology in metal processing and is widely used in the production of metals such as steel, aluminum, and copper. Rolling is a process that changes the shape and size of metal by squeezing it between two or more rollers. Through continuous pressure, the metal material is pressed and stretched between the rollers to form the desired shape. This process can change the thickness, width and length of the metal and improve its mechanical properties and surface quality. Among them, metal cold rolling can obtain more precise dimensions and better surface quality, while increasing the strength and hardness of the metal. The rolling mill in the prior art mainly feeds the metal strip manually, and then rolls the metal strip through the rollers under the action of the rollers to gradually reach the desired size and shape.
