Before using the leveling machine, we must conduct a thorough inspection. First, check the integrity of the installation of the bottom line to ensure good contact. We should equip the appropriate power supply according to the specified rated parameters, while also ensuring the stability of the power supply to avoid poor contact. Secondly, try to use original parts produced by the manufacturer and avoid modifying the leveling machine as much as possible.

We should equip a suitable power supply according to the specified rated parameters, while ensuring the stability of the power supply to avoid poor contact. Secondly, try to use original parts produced by the manufacturer and avoid modifying the leveling machine. Regularly wipe the appearance and marks of the machine to keep it free from rust and oil stains, clean the working rollers and support rollers to ensure they can work normally without cracks. However, ifLeveling Machinethere is smoke or abnormal noise during operation, please immediately turn off the leveling machine and stop working, otherwise, a fire may occur, and be sure to turn off the power. The leveling machine should be maintained as required to extend its service life. Always keep the parts of the leveling machine clean to ensure better operation.
How to solve the deviation problem of the leveling machine?
To improve production efficiency, the leveling machine may overlook some details during operation, such as material deviation and slipping. How to solve these problems? Let's take a look at the causes of the leveling machine's deviation.
1. The feeder andLeveling Machineare not on the same plane and need to reinstall the equipment.
2. When this problem is found at the opening of the paper, the deviation can be corrected by adjusting the position of the coil on the uncoiler.
3. The compression on both sides of the leveling machine's roller is unbalanced, requiring light side unloading of the chain, heavy side lifting of the chain, or heavy side unloading of the chain and light side pressing of the chain.
4. The center of the correcting wheel does not coincide with the center of the original uncoiling direction. When thick plates are opened, the clamping force of the rectifying wheel can prevent the steel plate from deviating. However, when the plate is opened, the clamping force of the plate has exceeded the yield strength of the plate, causing slight deformation at the edges of the plate, leading to deviation. The thinner the plate, the more pronounced this phenomenon.
What is the role of the working roller of the leveling machine?
As we all know, the leveling machine consists of many parts, among which the working roller is an important component. What role does the working roller of the leveling machine play during use?
1. The overall tilt adjustment of the upper row of rollers, the upper row of rollers is installed on a tiltable beam, and the curvature from the entrance to the exit gradually decreases. It can achieve large and small deformations, with faster straightening speed and convenient adjustment. Therefore, it is widely used.
2.Leveling MachineEach roller can be adjusted independently, and each upper roller has an independent bearing box and speed adjustment mechanism to ensure any height adjustment. In addition, collective adjustment can usually be made relative to the upper part of the lower moving frame, achieving higher straightening accuracy. However, the structure is complex, so in practice, the number of rollers is usually small.
3. The height of the upper row of rollers is adjusted in parallel. The upper row of rollers is fixed on a parallel lifting beam, and the group can only be adjusted up and down in parallel, so the roller pressure is the same, and the structure is relatively simple. However, this adjustment method can only achieve higher straightening accuracy with a smaller effective bending deformation, otherwise, it will produce larger residual curvature. To solve the above shortcomings, the upper and lower rollers are usually adjusted separately, and this structural scheme is widely used for straightening medium and thick plates.
