Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to an adjustable rolling device for manufacturing metal materials. Background Technology

[0002] Metal material manufacturing is the process of processing metal raw materials into products with specific shapes and properties. It encompasses processes such as smelting, casting, plastic forming, welding, and surface treatment. Smelting extracts pure metals or alloys through pyrometallurgy, hydrometallurgy, and electrolysis; casting pours molten metal into molds to form the product; plastic forming utilizes the plasticity of metals through forging and rolling; welding achieves metal connection; and surface treatment improves performance. It is widely used in aerospace, automotive, electronics, and construction fields, and is now developing towards green, intelligent, high-performance, precision, and lightweight directions, making it an important foundation of modern industry.

[0003] Currently, when processing metal sheets, rolling mills are used to plastically deform the metal sheets to achieve thickness reduction, surface smoothing, or shape change. However, the pressure rollers of the rolling mill are usually directly exposed to the air. Metal dust floating in the air in the workshop will settle on the surface of the pressure rollers, and debris or dust particles will embed into the surface of the sheet, forming pits, scratches, or irregular patterns. The surface roughness of the product exceeds the standard, which directly affects the appearance and subsequent coating, welding and other processes, and affects the processing efficiency of metal sheets.

[0026] Furthermore, there are two auxiliary mechanisms, which are arranged in a front-to-back configuration.

[0027] Furthermore, auxiliary mechanisms are used to clean debris and dust from the surface of the pressure rollers, preventing them from forming indentations or scratches on the sheet metal surface, ensuring the smoothness and precision of the sheet metal surface, reducing wear of the pressure rollers by hard particles, and the electric push rod 12 can adjust the contact pressure between the collection box 6 and the upper pressure roller 9 to adapt to the cleaning needs under different working conditions, thereby improving the processing efficiency of the rolling device for metal sheets.

[0028] Furthermore, electric push rods 12 are fixedly installed on the upper surface of each of the four mounting boxes 5.
