Introduction to the process and performance of cold roll forming machine

The cold roll forming machine is a new technology that saves materials, saves energy and effectively forms sheet metal. Using this process, not only can produce excellent steel products, but also can shorten the product development cycle, increase production capacity, and thereby improve the company's market competitiveness.

The general cold bending forming process includes: single sheet forming, roll forming, continuous forming and joint forming.

The principle of the cold roll forming machine is that each passing force is uniform, which can extend the service life of the roll. In production, the forces should be balanced, the processing should be accurate, and the device adjustment should be convenient. The cold bending machine ensures the strength of the raw materials, improves the quality of the supporting steel arch, greatly improves the work efficiency, and the operation is simple and clear. Compared with the two, both have excellent running performance.

Cold bending is to rotate the steel bar around a steel roll with a diameter of D to an angle α without cracks.

Cold bendability and elongation are both indicators of the plasticity of steel bars. The larger the cold bending angle α, the better the plasticity of the steel, and the smaller the diameter D of the steel coil.

Cold-formed steel (cold-formed steel) refers to finished steel products with various cross-sectional shapes that are bent from steel plates or strips in a cold state.

In recent years, cold-formed steel as an important structural component has been widely used in many fields such as construction, automobile manufacturing, shipbuilding, electronics industry and machinery manufacturing. Its products range from ordinary guide rails, doors and windows and other structural parts to some special profiles manufactured for special purposes. The types are very wide.
