As an important metal machining equipment, the machine is widely used in the machining process of steel, aluminum and other metal materials. Its main function is to correct the metal sheet by mechanical means so as to achieve the ideal leveling degree and geometric shape. This paper will deeply discuss the working principle of leveling machine and its application in industrial production.

I. Working principle of leveling machine: The working principle of leveling machine is based on the elastic and plastic deformation characteristics of leveling machine. The leveling machine makes the metal sheet plastic deformation through the action of mechanical force, which eliminates the internal stress and leveling degree. Its main work steps are as follows:

Material feeding: Initially, sheet metal is fed into the feeding area of the leveling machine. During this process, the roller system guides the sheet to the leveling machine's working area.

The role of the upper roll and the lower roll: The leveling machine is usually composed of a set of upper roll and a set of lower roll. The clearance between the upper and lower rollers can be adjusted as needed. When the sheet metal passes through the gap between the upper and lower rollers, the roller system applies pressure to cause plastic deformation of the sheet metal.

Plastic deformation: The metal sheet under the action of the upper and lower roller pressure, elastic and plastic deformation. Internal stresses and distortions are gradually eliminated, and the sheet gradually becomes more flat.

Discharge: After a series of leveling processes, the treated metal sheet leaves from the discharge port of the leveling machine to achieve the ideal flatness and geometry.

2. Application of leveling machine: leveling machine has a wide range of applications in industrial production, which is mainly reflected in the following aspects:

Sheet metal machining: leveling machine is widely used in the production and processing of sheet metal, such as cold-rolled steel plate, hot-rolled steel plate, stainless steel plate and so on. Through the correction of metal sheets, higher flatness and surface quality can be obtained to meet the needs of various industrial fields.

Automobile industry: In the automobile manufacturing process, a large number of metal sheets are needed as parts of the automobile. leveling machine can make these metal sheets reach the precise flatness and geometric size, ensuring the structure and appearance quality of the car.

Home appliance manufacturing: Home appliance manufacturing, such as refrigerators, washing machines and other products, usually need to use metal sheets to make shells and components. leveling machine can guarantee the leveling of these metal sheets and make the appearance of the final product more beautiful.

Construction: In the field of construction, metal materials are widely used in structural and exterior decoration. Through the treatment of leveling machine, the metal sheet that meets the building standard can be obtained to ensure the stability and beauty of the building.

Conclusion: As an important metal processing equipment, leveling machine plays an indispensable role in modern industrial production. By applying the principle of elastic plastic deformation, the leveling machine can effectively improve the flatness and geometric shape of the metal sheet, meet the production demand of all walks of life and promote the progress and development of industrial manufacturing.
