Cold-formed steel is an economical section and energy saving material and a new type of steel with strong vitality. It is widely used in various fields of the national economy, such as highway guardrail board, steel structure, cars, containers, steel form and scaffolding, railway vehicles, ships and Bridges, steel sheet pile, transmission tower, other 10 categories and so on. There are two different forming processes in the production of cold bending hollow square rectangular steel. One is to form a circle and then square or rectangular; The other is straight into a square or rectangle. At present, in the field of rectangular steel tube forming, the process of directly forming into a square or a rectangle is more advanced than that of first forming into a circle and then changing into a square or a rectangle. First round and then square or rectangular process to the steel strip or coil material damage; And direct into the square or rectangular of the process, in the molding process will not damage to the material, it can keep the mechanical and physical properties of raw materials, ensure the excellent product.
C section steel is one of the main materials used in the manufacture of steel structure, its components can be purlins, bracket, beams and other different products.
Steel structure is a structure mainly made of c-section steel, which is also one of the common structural forms in modern architectural engineering. Due to some characteristics of c-section steel, such as high strength, light weight and large stiffness, it is particularly suitable for making large-span, ultra-high and super-heavy structural parts. In addition, the homogeneity and isotropy of C section steel are also better. So it is also an ideal elastomer, which is consistent with the required performance requirements.
In addition, the plasticity and toughness of C section steel enable it to have large deformation, meanwhile it can bear the dynamic load well. C section steel as a material, through different processes are processed into different shapes, with a strong practical application in the actual construction, the use value of C section steel is fully developed.
Equipment is critical. It is difficult to produce high quality C section steel by cold rolling, so we used C purlin machine. After the material enters from the tail of the C purlin machine, it is pressed by various pressure rollers, and then the formed C section steel is output from the head.This is not only greatly optimizes the necessary production and processing technology, but also improves the production capacity and ensures that the C section steel products have uniform wall thickness and complex interface shapes.
In order to achieve accurate wall thickness, the mold is composed of a precise upper die and some size specifications of the same size of the lower die in the pressing of C section steel. They will be installed in place before processing, not only to ensure that the upper die and the bottom die can be smooth, but also to ensure that the four peripheral clearance is uniform, so that the pressing of the C section steel wall thickness is uniform
