Roll forming is a type of rolling that involves continuously bending long strips of metal sheet (typically coiled steel) into the desired cross-section.
Design the mold shape and number of groups according to the required size. The shrinkage ratio of each group of cold bending is different. Through cold bending group by group, the final desired size can be achieved. Combined with electronic control system, hydraulic system, shearing system and counting encoder to realize automated operation.

Application Scenarios :
Equipment Production Line:
Solar photovoltaic brackets are special brackets designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. The general materials are aluminum alloy, carbon steel and stainless steel.
The materials of solar support system related products are carbon steel and stainless steel. The surface of carbon steel is hot-dip galvanized and will not rust for 30 years of outdoor use. The characteristics of solar photovoltaic bracket system are no welding, no drilling, 100% adjustable and 100% reusable.
The global energy crisis has promoted the rapid development of the new energy industry, and solar energy is the most important basic energy among various renewable energy sources; therefore, the photovoltaic industry, which is a solar power generation technology that converts solar radiation energy into electrical energy, has developed rapidly; in the old concept, the photovoltaic industry mainly includes the solar panel production chain, and the electrical control component production chain such as control devices and inverters.The advantages of using solar support systems in solar panel support go far beyond simple production and installation. Solar panels can also be flexibly moved according to the sunlight and seasons. Just like when they were first installed, the slope of each solar panel can be adjusted to different angles of light by moving the fasteners, and the solar panel can be accurately fixed in the specified position by re-tightening.
Challenges faced by solar photovoltaic bracket design solutions. One of the most important features of any type of solar photovoltaic bracket design solution is weather resistance. The structure must be strong and reliable, and can withstand atmospheric erosion, wind loads and other external effects. Safe and reliable installation, maximum use effect with minimum installation cost, almost maintenance-free, reliable repair, these are important factors to consider when choosing a solution. Highly wear-resistant materials are used in the solution to resist wind, snow loads and other corrosion effects. Aluminum alloy anodizing, ultra-thick hot-dip galvanizing, stainless steel, anti-UV aging and other technical processes are comprehensively utilized to ensure the service life of solar brackets and solar tracking.
The maximum wind resistance of solar brackets is 216 km/h, and the maximum wind resistance of solar tracking brackets is 150 km/h (greater than a level 13 typhoon). Compared with traditional fixed brackets (the same number of solar panels), the new solar module bracket system represented by solar single-axis tracking brackets and solar dual-axis tracking brackets can greatly increase the power generation of solar modules. The power generation of solar single-axis tracking bracket components can be increased by 25%, while solar dual-axis brackets can even increase by 40% to 60%.
Equipment composition :
The entire production line integrates multiple technologies such as leveling, feeding/punching, forming, and cutting.
The entire production line consists of a feeding system, a punching system, a forming system, a cutting system, an electronic control system, etc.
Related requirements The photovoltaic support structure must be strong and reliable, and be able to withstand atmospheric erosion, wind loads and other external effects. It should be safe and reliable to install, achieve maximum use effect with minimum installation cost, be almost maintenance-free, and have reliable repair. Good support needs to consider the following factors: (1) The strength of the material must withstand climate factors for at least thirty years. (2) It should remain unaffected by extreme weather such as blizzards or typhoons. (3) The support must have a groove design to place wires to prevent electric shock. (4) The power equipment must be installed in a non-environmentally exposed and easy to maintain regularly. (5) It must be easy to install. (6) The cost must be reasonable. High-quality support systems must use computer simulation software for extreme weather conditions to verify their design, and undergo rigorous mechanical property tests, such as tensile strength and yield strength, to ensure product durability.
Technical difficulties :
In fact, the manufacturing process of finished brackets is not simple, and high-quality products often have multiple technical patents. The following is an example of assembled steel brackets.
First, high-quality steel sections usually have a high level of galvanizing process. According to the requirements of national standards, the average thickness of the galvanized layer should be greater than 50μm, and the minimum thickness should be greater than 45μm. In fact, although the average thickness of the galvanized layer of many products can meet the requirements, the minimum thickness is less than 40μm, and pitting often occurs in actual use. Halogens corrode steel very quickly, and within a year, it may cause the weakening of the overall support structure and cause safety hazards. Therefore, it is not easy to achieve a highly uniform galvanizing process.
Secondly, the connection of steel sections is a technical difficulty. A complete set of effective connection methods not only includes ingenious ideas on the connectors, but also cooperates with the design of the back holes and bite teeth of the channel steel. This involves stamping, casting and other aspects of steel metallurgy technology.
In addition, double-sided channel steels used to bear large loads must be welded back to back. There is a big gap in the level between various welding processes. Pressure laser welding can ensure uniform connection of the entire section, and the two channel steels are completely integrated and bear the force together; while electric welding technology can only fix the two channel steels partially together, and the force form is closer to that of a composite beam. In order to improve the bearing capacity, some steel sections also add cold rolling of stiffening ribs to the channel steel.
In short, there are many technical difficulties in the production process of assembled steel brackets, which requires metallurgical engineering and technical personnel to overcome technical barriers and further reduce its use cost.
