The roller - type steel plate leveling machine is mainly composed of multiple leveling rollers arranged in an up - down staggered manner. When the steel plate enters the leveling machine, it is conveyed forward under the drive of the power device and passes through these leveling rollers. There is a certain gap between the upper and lower rollers, which can be adjusted according to factors such as the thickness of the steel plate. When the steel plate passes through each group of leveling rollers, it is repeatedly bent in the forward and reverse directions by the upper and lower rollers. For example, a group of upper rollers will bend the steel plate upward, and then the next group of lower rollers will bend the steel plate downward. Through this repeated bending process, the stress distribution inside the steel plate gradually changes.
Just like continuously bending a bent metal bar back and forth, the originally uneven stress will gradually become uniform, and the original deformations of the steel plate (such as waviness, arch shape, etc.) will also decrease accordingly. Moreover, as the number of groups of leveling rollers increases, the steel plate is corrected more thoroughly, and the flatness is higher.
Elastic Deformation Recovery and Leveling:
The steel plate itself has elasticity and plasticity. During the repeated bending process by the leveling rollers, the steel plate undergoes elastic deformation and a small amount of plastic deformation. When the elastic deformation part leaves the leveling rollers, it has a tendency to return to its original state.
Due to the repeated forward and reverse bending, the elastic recovery forces of various parts of the steel plate interact with each other, enabling the steel plate to finally reach a relatively flat state. This leveling method can effectively handle steel plates with a wide range of thicknesses, from thin sheets to medium - thick plates of a certain thickness.
Steel plate leveling machines are mainly used in the following numerous industries:
Iron and Steel and Metal Processing Industry
Plate Production and Processing: During the production of steel plates, the hot - rolled or cold - rolled steel plates are leveled to eliminate deformations such as waves and bends generated during the production process. This improves the flatness and quality of the steel plates, making them meet the requirements for subsequent processing and use.
Metal Products Manufacturing: The plates required for the production of various metal products are leveled. For example, metal structural components for construction and part blanks in machinery manufacturing. This ensures the dimensional accuracy and flatness of the products, improving production efficiency and product quality.
Automotive Manufacturing Industry
Vehicle Body Manufacturing: Many components of the vehicle body, such as body panels, door panels, engine hoods, and trunk lids, are made of metal plates. Steel plate leveling machines are needed to level these plates with high precision to ensure the appearance quality and assembly accuracy of the vehicle body.
Component Production: A large number of metal plates are also used in components such as automobile engines and chassis. The leveling machine can level the plates used for these components, ensuring the flatness and dimensional accuracy of the components and improving their performance and reliability.
Construction Industry
Building Curtain Walls: In the manufacturing of building curtain walls, metal plates need to be cut into various shapes and sizes while ensuring their flatness. Steel plate leveling machines can process metal plates to the required flatness to meet the manufacturing requirements of curtain walls.
Steel - Structure Buildings: A large number of components such as steel beams, steel columns, and steel trusses used in steel - structure buildings are usually welded or assembled from steel plates. Leveling the steel plates can improve the manufacturing accuracy and quality of the components, ensuring the overall stability and safety of steel - structure buildings.
Home Appliance Industry
Outer Shell Manufacturing: The outer shells of home appliances such as refrigerators, washing machines, air conditioners, and televisions are usually made of metal plates. Steel plate leveling machines are required to level these plates to ensure the flatness and aesthetic appearance of the outer shells, improving product quality and market competitiveness.
Internal Structural Components: Some internal structural components of home appliances, such as brackets and partitions, also use metal plates. Leveling these plates can ensure their installation accuracy and service performance.
Electronic Equipment Industry
Electronic Product Outer Shells: The outer shells of electronic products such as mobile phones, tablets, and laptops have extremely high requirements for flatness and precision. Steel plate leveling machines can provide high - precision metal plates that meet the requirements for these products, ensuring the thinness and beauty of electronic products.
Electronic Component Manufacturing: During the production of electronic components, some metal substrates or plates need to be leveled to ensure their surface flatness and dimensional accuracy, improving the performance and quality of electronic components.
