Description

Technical Field

[0002] Thin steel usually refers to steel with a smaller thickness, generally between 0.2 mm and 6 mm. Compared with thick steel plates, thin steel is more flexible and can be more easily bent, formed and processed. It is suitable for some products that require complex shapes. Compared with thick steel plates, the raw material cost of thin steel is usually lower. At the same time, due to its light weight and easy processing, it can also reduce processing and transportation costs.

[0003] Cold bending machines perform processing at room temperature, unlike hot bending which requires high temperature treatment. Therefore, the original physical and mechanical properties of thin steel, such as hardness and strength, can be maintained. The softness of thin steel may cause deviations or irregular bending angles during the bending process. The correction mechanism can help adjust and correct these deviations to ensure that the bending angle and shape meet the requirements. The correction mechanism can eliminate defects such as deformation, distortion or wrinkles that may occur in thin steel during the bending process, thereby improving the quality and appearance of the processed product.
