Cold roll forming is a new process and new technology of sheet metal forming that is material-saving, energy-saving and efficient. Using this process, not only can we produce high-quality steel products, but also we can shorten the product development cycle, improve production efficiency, thereby improving the market competitiveness of the cold roll forming machine manufacturer china.
The general cold roll forming process includes: single sheet forming, roll forming and continuous forming, combined forming.
The single sheet forming process is to cut the sheet into a specified length in advance, and then send the sheet into the shelf panel roll forming machine through material selection. After rolling, the sheet can be directly collected and stored, which is especially suitable for products that are easily deformed after the sheet is formed. It is mostly used for small batch production. It has many advantages such as simple equipment, low investment, and small occupied area.
The process of roll forming and continuous forming is basically the same. The difference between them is that the joints of the continuously formed plates must be welded to make the plates continuously formed; the roll forming is a single roll supply. The equipment investment and floor space of the cold roll forming machine required by these two processes are relatively big.
The combined forming process is a forming process for processing special steels. Sectional steel has special requirements for forming processes, requiring complex cold roll forming equipment, which is suitable for processing high-strength plates. The equipment requirements are complex and the investment neededis high.
In recent years, cold-formed 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 have a very wide range of types, ranging from ordinary structural parts for guide rails, doors, windows and other things to some special profiles manufactured for special purposes.
