Steel Cold Roll Forming Machine And its Forming Process Steel Cold Roll Forming Machine is widely used for its energy-saving and environmentally friendly characteristics. It uses less steel to complete the specified load, and no longer depends on increasing the amount of sheet used or improving the mechanical properties of the material to meet the load. Requirement, but to improve the mechanical properties of the section steel by changing the cross-sectional shape of the section steel product.
Steel Cold Roll Forming Machine originated in 1838. Russia, the United States, and the United Kingdom used a press or cold drawing machine to produce a single steel product. This is the prototype of a cold-formed steel unit. In 1910, the United States took the lead in the construction of cold-formed steel forming units, which resulted in a continuous cold-form forming process. Cold-formed steel began to form industrial production, and thus it was on the stage of the world.
The general cold forming process includes: single sheet forming, roll forming and continuous forming, and joint forming.
1, single sheet molding
The single sheet forming process is to cut the sheet into a predetermined length in advance, and then feed the sheet into the molding machine through a selective roll. The profile after rolling can be directly collected into the warehouse, especially suitable for cutting and deforming products after sheet metal forming, and is mostly used for small batch production. The advantage is that the equipment is simple, the investment is low, and the floor space is small.
2, roll forming and continuous forming
The processes of roll forming and continuous forming are basically the same, and they differ in that the continuously formed sheet joints must be welded to continuously form the sheet; the roll forming is a single roll supply. The equipment investment and floor space required for these two processes are large.
3, joint molding
The joint molding process is a molding process for processing special steel. The profile steel has special requirements for the molding process, and requires complicated molding equipment, which is suitable for processing high-strength plates. Equipment requirements are complex and investment is high.
With the continuous development of technology, cold forming technology has been widely used for its energy saving, environmental protection and high efficiency. Cold-formed steel products are also widely used in many industries such as construction, bridge, vehicle manufacturing, container production, machinery manufacturing, etc. The use of it has played a huge role.
