cold roll forming machines are widely used and have a fast updating structure. Therefore, the demand is high and the requirements for products are increasing. The development prospects of cold roll forming machines are also quite broad. There are many types of cold roll forming machines, and they have a long history of development. In recent years, the market demand for cold-formed steel has gradually increased, the application scope of cold roll forming machines has been continuously expanded, and the market prospects are quite broad.
cold roll forming machines are the focus of the development of cold roll forming equipment. Cold-formed steel originated in Russia, the United States, the United Kingdom and other countries in 1838, and these countries used press machines or cold drawing machines to produce single-type steel products, which is the embryonic form of cold-formed steel units. In 1910, the United States took the lead in building cold-formed steel units, which can produce a continuous cold roll forming technology process. The development of cold roll forming equipment in these years can be described as rapid and it has occupied the main field of our entire forming equipment in the entire equipment industry, playing a very important part.
Chinese enterprises have been conducting key research and development of environmentally friendly cold roll forming equipment in recent years. cold roll forming machines urgently need to develop stainless steel, galvanized sheet, high-strength, ultra-high-strength low-alloy materials, ultra-thick, ultra-thin cold-formed steel products, and other materials. Cold-formed steel is the main material for manufacturing light steel structures. It has multiple ultra-thin, reasonable, and complex cross-sections that cannot be produced by hot rolling and can be combined with online punching, online riveting, online welding and other processes.
Before using the cold roll forming machine, you must check the machine and complete a set of protective steps.
When using the cold roll forming machine, be sure to check whether the upper and lower molds are firmly matched and whether the positioning devices at each point meet the processing requirements.
Before use, the cold roll forming machine can be idled for one to two minutes, adjust all parts back to their original position, and confirm that there are no defects or problems before proceeding to the next step of operation.
When operating the cold roll forming machine, one person should listen to the commands. This avoids the confusion caused by multiple people operating at the same time.
In the past half century, cold roll forming machines have developed into an effective sheet metal forming technology. 35% to 45% of the strip steel rolled in North America is processed into products through cold roll forming, which is more than the steel used in the automotive industry.
In recent years, as an important structural component, cold-formed steel products have been widely used in many fields such as construction, automobile manufacturing, shipbuilding, electronics, and mechanical manufacturing. The product range varies from ordinary guide rails, doors, windows, and other structural components to special profiles that are extremely diverse and manufactured for special purposes.
The unit weight sectional performance of cold-formed steel is better than that of hot-rolled steel products, and it has high surface finish and dimensional accuracy. Therefore, cold-formed steel can replace hot-rolled steel to achieve the dual effect of saving steel and energy. The development of cold-roll steel is highly valued.
