Embodiment 1

[0043] See attached figure 1 , a cold-formed steel forming process, comprising the following steps:

[0044] S1, unwinding. In the actual production process, the cold-formed section steel can use a section steel forming machine to realize streamlined production operations. The strip steel used in production can be one of ordinary carbon steel, low alloy steel and high strength steel. Before the operation starts, the strip steel is coiled and set on the uncoiler. Unwinding can realize continuous production operation and ensure the efficiency of production operation. After the unwinding of the strip steel is completed, the staff can clean the strip steel online on the assembly line; during operation, the staff can clean the upper and lower surfaces of the strip steel with a cleaning agent to remove foreign matter such as oil stains and debris on the surface of the strip steel; After cleaning, the staff can carry out online drying treatment on the surface of the strip steel on...

Embodiment 2

[0057] See attached figure 2 , a kind of cold-formed steel, which is made by the above-mentioned cold-formed steel forming process as a whole, and includes a steel body 1, and the material of the steel body 1 can be one of ordinary carbon steel, low-alloy steel and high-strength steel. The surface of the shaped steel body 1 is evenly coated with an insulating protective layer, which is an epoxy resin insulating layer 2; while ensuring the structural strength of the shaped steel, the epoxy resin insulating layer 2 can meet the user's requirements for the insulating performance of the shaped steel.

Abstract

The invention discloses cold bending profile steel and a forming process of the cold bending profile steel, and relates to the technical field of profile steel forming. The cold bending profile steelforming process comprises steps like unreeling, surface treatment, cold bending forming, cutting and post-processing, wherein the step of surface treatment comprises the two sub-steps of lubrication treatment and film coating treatment. By adopting the forming process, the forming quality of the surface of the profile steel can be improved, the physical and mechanical properties of the profile steel are ensured, and requirements of users for the insulation performance of the profile steel are met. In addition, the cold bending profile steel comprises a profile steel body, wherein the surface of the profile steel body is uniformly coated with an epoxy resin insulation layer; the structural strength of the profile steel is guaranteed; and meanwhile, the epoxy resin insulating layer enables the profile steel to have good insulating performance.

Description

technical field [0001] The invention relates to the technical field of profiled steel forming, in particular to a cold-formed profiled steel and its forming process. Background technique [0002] Cold-formed steel refers to finished profiles of various cross-sectional shapes bent by steel plates or strips at room temperature. Thin-walled cold-formed steel is the main material for making light steel structures. Cold-formed steel has a variety of ultra-thin, reasonable and complex sections that cannot be produced by hot-rolled steel; compared with hot-rolled steel, the radius of gyration of cold-formed steel can be increased by 50% under the same cross-sectional area- About 60%, the section moment of inertia of cold-formed steel can be increased by about 0.5-3.0 times, so the material strength can be used more reasonably. Therefore, compared with ordinary steel structures, cold-formed steel can save about 30%-50%. [0003] The existing invention patent with publication numbe...
