4 High Roller Leveling Machine

• 4 High Roller Leveling Machine is a kind of industrial equipment used to process plates, usually used to level or straighten metal plates to reduce the warping, waving, bending, and other surface unevenness of the material.

•  KINGREAL CEILING MACHINERY 4 High Roller Leveling Machine usually uses four rolls to process the metal material so as to ensure its surface flatness. The specific structure consists of two sets of work rollers, usually one set is located above and the other below, and the sheet metal is leveled by pressure between the upper and lower rollers.

  
  

• This sheet metal leveling machine is widely used in the United States, Canada, the United Kingdom, Belgium, Brazil, Australia, Germany and many other countries.
  

     

1. Basic structure of sheet metal leveling machine

Four working rolls: The four heavy leveler mainly consists of two support rolls on the top and bottom and two leveling rolls on the top and bottom. There is a pair of rolls on the top and a pair of rolls on the bottom. The plate passes between the four rolls and is controlled by the pressure and gap between the rolls for leveling.

Upper work roll: Located above the plate, it is responsible for applying pressure to the upper surface of the plate.

Lower work roll: Located below the plate, it supports and levels the lower surface of the plate.

Supporting roller: to prevent the working roller from deformation during the process and to improve the leveling accuracy.

2. Working Principle of sheet metal leveling machine

The working principle of the four-weight leveling machine is based on the force state of the metal sheet between the rolls. By adjusting the gap and pressure between the four working rolls, the plate passing through is subjected to different degrees of bending and reverse bending, and finally the flatness of the material surface is realized.

3. Key working principle steps of sheet metal leveling machine:

Feeding: the metal sheet to be leveled enters the leveler from the feeding end.

Initial bending: When the metal sheet passes through the upper and lower working rollers, it will produce initial bending deformation. Depending on the thickness and material of the sheet, the leveler can apply appropriate pressure, causing controlled plastic deformation of the sheet surface.

Reverse bending: As the sheet passes between the four rolls, the direction of force will change. The lower work roll will reverse correct the plate after bending. This process is repeated several times to remove stress and warpage from the sheet.

Multiple Leveling: Through many repeated bending and releasing, the irregular deformation of the plate such as wave and bend is gradually corrected and the surface tends to be flat.

The support rollers and leveling rollers bearings are mounted on a movable plate. After the upper leveling roller frame was electrically lifted, the movable plate will be driven out by the motor. Then after removing the bearing front the baffle, the roller can be taken our from the fixed rear bearing, so it’s convenient and save much time to clear leveling rollers, support rollers, support plated etc.

In addition to the common 4 high roller leveling machine, KINGREAL CEILING MACHINERY also offers a 6 high roller leveling machine to meet customer needs in various applications. This 6 high roller leveling machine is equipped with three upper rollers and three lower rollers, with additional support rollers that evenly distribute pressure for higher leveling accuracy. This makes the 6 high roller leveling machine perform exceptionally well when handling thicker materials or materials with higher yield strength.

The 6 high roller leveling machine is designed to handle higher-strength materials such as high-strength steel plates and cold-rolled steel. Compared to 4 high roller leveling machines, the additional support rollers in the 6 high roller leveling machine distribute the pressure applied to the material, ensuring no deformation occurs during leveling. This design makes the 6 high roller leveling machine suitable not only for thicker plates but also for harder metals, improving the reliability and consistency of leveling.

In the manufacturing process, KINGREAL CEILING MACHINERY's metal plate leveling machines use high-quality raw materials with high hardness and strength to make roller wheels. These high-quality rollers not only have excellent wear resistance and deformation resistance, but also can withstand high working pressure, thus ensuring excellent performance in the leveling process.   The precise fit of the upper and lower rollers allows the sheet metal to be stretched and compressed repeatedly. This process effectively releases the stress inside the material, making the leveling effect of the plate significantly improved.   In addition, the roller design of the KINGREAL CEILING MACHINERY plate leveller machine is carefully optimized to ensure an even distribution of pressure, further enhancing the levelling effect. Such a high standard manufacturing process not only improves the performance of the metal plate leveling machine, but also provides customers with more reliable leveling solutions, helping all kinds of metal processing enterprises to achieve higher production efficiency and product quality.
