The roll forming machine has the principle of the average force of each pass, which can prolong the service life of the roll. In production, it should be designed with balanced force, accurate processing, and convenient installation and adjustment. The forming machine ensures the strength of the material, 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 good working performance.
Roll forming is a new process and new technology of sheet metal forming with material saving, energy saving and high efficiency. Using this process, not only can high-quality steel products be produced, but also the cycle of product development can be shortened, production efficiency can be improved, and the market competitiveness of enterprises can be improved.
The general roll forming process includes sheet forming, roll forming, continuous forming and joint forming.
The single-sheet forming process is to cut the sheet into a specified length in advance, and then send the sheet to the forming machine through the material selection roller. The rolled profiles can be directly collected and put into storage, especially suitable for the products that are easily deformed after the sheet is formed, and are mostly used for small batch production. Its advantages are simple equipment, low investment and small footprint.
The process of roll forming and continuous forming is basically the same. The difference between them is that the joints of the continuously formed sheets must be welded, so that the sheets can be continuously formed and processed; the roll forming is a single roll supply. The equipment investment and floor space required by these two processes are relatively large.
The joint forming process is a forming process for processing special steel. The section steel has special requirements for the forming process and requires complex forming equipment, which is suitable for the processing of high-strength plates. The equipment requirements are complex and the investment is high.
In recent years, rolled steel products have been widely used as important structural parts in many fields such as construction, automobile manufacturing, shipbuilding, electronic industry and machinery manufacturing. Its products range from ordinary rails, doors and windows and other structural parts to some special profiles made for special purposes, with a wide range of types.
