The leveling machine produced is also called flat machine and straightening machine. This machine is suitable for leveling various cold and hot rolled plates. Because of its convenient and simple operation, it is widely used in many industries such as machinery, metallurgy, building materials, chemical industry, electronics, electric power, light industry, etc., especially in shipbuilding, rolling stock, boiler bridges, metal structure factories and other industries. necessary products.

Background

At the end of the 20th century, the world's steel rolling technology developed rapidly. Steel rolling production has made great progress in automation, high precision and continuity. Steel rolling production is an important production link and main method for rolling steel ingots or billets into steel products. Because the steel produced by the rolling method has the advantages of high productivity, strong continuity of the production process, many varieties, easy mechanization and automation, etc., and has higher performance and lower cost than products produced by forging, extrusion, drawing, etc. Low. At present, about 93% of steel is rolled into lumber. The rolling method is also widely used in the production of non-ferrous metals.

Working principle of plate leveling machine

Straightening is the post process of metal material processing. This process can greatly improve the quality level of products, and greatly improve various shape defects produced in the process of rolling, cooling and transportation. Such as: arc bends of rails, transverse and longitudinal bends of plates and strips, edge waves, sickle bends and other defects. Straightening machines have become indispensable equipment in rolling workshops, and are widely used in various factory workshops that use slabs as raw materials, such as automobile manufacturing plants and shipbuilding plants.

The working principle of the field straightening machine is the theory of plastic tension bending straightening. The internal uneven stress of the strip is generated in the rolling and leveling process. When the stress value reaches a certain level, it will cause the plate shape to be curved or wavy. The tension straightening machine utilizes the existence of internal stress to improve the shape of the plate. Under the action of the tension applied by the tension roller group, the strip to be leveled continuously passes through multiple groups of small-diameter bending rollers arranged alternately up and down and is sharply bent. The non-uniformity of the length of each longitudinal fiber of the strip produces different degrees of plastic extension along the length direction under the combined action of stretching and bending. The stretching and bending straightening technology makes the length of each longitudinal fiber tend to be consistent. Thereby, the uneven distribution of internal stress is reduced, and the plate shape defects caused by the length difference of longitudinal fibers are eliminated.

Using a precision leveler to level the workpiece can achieve extremely high flatness, and the internal stress is also significantly reduced. The workpiece to be leveled is bent alternately between the separately driven leveling rollers to achieve workpiece leveling. The upper and lower rows of leveling rollers are staggered and installed to form a wedge-shaped section that opens in the running direction.

Large bending deformations occur at the inlet, where the material deforms until it reaches a plastic state. At exit, the workpiece is only in an elastic state and leaves the leveler with a flat surface.

The leveler can be set up quickly and easily thanks to the upper beam leveling roller frame feed system. Enter the setting values through the control panel in different regional languages. The adjustment of the upper roller frame is performed by the motor and worm gear mechanism, and the adjustment accuracy reaches 0.02mm.

High-performance positioning controls ensure instantaneous adjustment value changes. The setup of the machine tool is carried out through the teaching system, using the memory of the workpiece number. When reprocessing the same type of material, the upper roll frame automatically moves to the correct position after entering the workpiece number.
