The Roller box of the straightening line unit plays an important role in the straightening line unit, as follows:

Adapt to different material and process requirements

Adjust spacing and pressure: The spacing and pressure of the roller box are usually adjustable, and can be flexibly adjusted according to the thickness, width, hardness, and specific production process requirements of different materials. For thicker and harder materials, the pressure and spacing of the roller box can be increased; For thinner and softer materials, it is necessary to reduce pressure and appropriately narrow the spacing to achieve good straightening effect.

Implementing special functions: In some special straightening processes, such as scale breaking straightening, the roller box can also be equipped with special devices or structures, such as Scale breaking rollers, to remove impurities such as oxide scales on the surface of the material, improve the surface quality of the material, and meet the requirements of subsequent processing procedures.

Ensure the stability of material transmission

Guidance and positioning: The roller shaft in the roller box provides accurate guidance for material transportation, ensuring that the material advances along the predetermined path in the straightening line unit. Especially in the process of high-speed straightening, it can effectively prevent material deviation, snaking and other phenomena, ensure the stable passage of materials through various processing steps, and avoid equipment damage or product quality problems caused by material deviation.

Control tension: The friction between the roller box and the material can to some extent control the tension of the material during transportation. Appropriate tension is crucial for maintaining the stability of materials during the stretching and straightening process. It can prevent relaxation and accumulation of materials due to low tension, as well as avoid material breakage caused by excessive tension.

Realize straightening of materials

Bending effect: During the straightening process, the bending roller box applies bending force to the metal material, causing it to undergo a certain degree of bending deformation. For plates or strips with defects such as wave shape and buckling, the internal stress can be redistributed through the action of the bending roller box, laying the foundation for subsequent straightening.

Straightening function: The straightening roller box is responsible for performing reverse straightening operation on the material after it has been bent. By precisely adjusting the pressure and position of the Straightening Roller box, the material undergoes reverse deformation within its elastic limit, gradually eliminating bending deformation and achieving a flat state, improving the flatness and straightness of the material.

Easy to maintain and replace equipment

Whole replacement: The roller box is usually designed as a detachable and replaceable component. When the roller shaft, bearings, and other components inside the roller box are worn, damaged, or require maintenance, the entire roller box can be quickly removed from the straightening line unit and replaced with a new one, greatly reducing equipment downtime and improving production efficiency.

Convenient maintenance: The independent roller box structure also facilitates maintenance personnel to inspect, repair, and replace its internal components, reducing the difficulty and cost of equipment maintenance.
