In sheet metal processing, traditional leveling methods such as hammer, flame, plate rolling machine, etc. are no longer cost-effective processing technology, even a slightly advanced leveling press can not reduce the residual stress in the material. These internal stresses will be released through stamping, laser cutting or flame cutting, causing bending and deformation of sheet metal parts, affecting the subsequent process and its accuracy, resulting in time-consuming rework, delaying the processing process and increasing production costs. This is a problem that many companies do not want to face.

The rapid development of industrial automation, and the high degree of automation of sheet metal processing is inseparable from the precision leveling process. Now, more and more sheet metal processing enterprises use roll type leveling machine to ensure the precision and efficiency of sheet metal processing.

So what is the working principle of the roll leveling machine?

In fact, the principle of roller leveling is very simple and ingenious: the placement of the leveling rolls makes the sheet metal parts obtain multiple continuous alternating bending when processed in the machine. The degree of this bending varies from large to small, and the process is very similar to a decaying sine curve. Under the action of the leveling roller in this arrangement, the sheet metal parts after leveling can be extremely flat and almost all stresses are eliminated. In turn, the above annoying situation will not occur in the subsequent processing.

One point is very important, the number of leveling rollers depends on the thickness of the material, this is because: the more alternating bending times carried out in the roller machine, the smaller the diameter of the leveling roller, the less residual stress will be placed on the plate after machining, the better the leveling effect. When selecting a roll leveling machine, ensure that the leveling roll has sufficient support to prevent and leveling the machine from buckling. In addition, the leveling equipment must be equipped with a protection design to prevent misoperation, and it is easy to clean and maintain, avoid long downtime and affect daily production, and thus improve the utilization of the machine.
