Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a rolling mill for processing metal products. Background Technology

[0002] Rolling is a material processing technique that involves continuously extruding and deforming metal materials to adjust their shape and size. This process requires high temperatures and typically uses a rolling mill or calender. Rolling is widely used in the manufacture of various machinery, building structures, and metal products. It offers numerous advantages: improving material properties such as strength, hardness, and toughness; controlling the size and shape of materials; and enabling higher precision in finished products. Furthermore, rolling allows for the simultaneous execution of multiple processes, saving production costs and time. As a crucial material processing technology, rolling is widely applied across various fields.

[0003] Chinese patent discloses a metal rolling apparatus (authorization announcement number CN 218049659 U). This patented technology can rotate a cross handle, causing one of the threaded rods to rotate. When the threaded rod rotates, it drives the rollers to rotate. Due to the transmission connection of the belt, the two rollers rotate simultaneously, causing the two threaded rods to rotate at the same time. When the two threaded rods rotate, the two rectangular blocks move up and down, thereby driving the second and third rollers to move downwards. Due to the interaction between the rollers, the metal sheet gradually curls, eliminating the need for additional curling work and increasing the efficiency of metal rolling. However, when the volume and length of the metal increase to a certain extent, the rolled metal will be severely deformed. After the metal is bent and deformed, workers need to straighten it to a straight state, which greatly increases the workload. After rolling to a certain length, the metal is prone to uneven or skewed rolling, affecting the rolling effect. Moreover, when rolling metal products, dust and waste on the surface can cause damage to the metal products during the rolling process.

[0004] Therefore, those skilled in the art provide a rolling mill for processing metal products to solve the problems mentioned in the background art. Utility Model Content
