With the global push for renewable energy and the rapid development of the solar photovoltaic industry, the demand for high-quality, durable, and efficient PV brackets is growing exponentially. As a core component of solar power systems, PV brackets bear the weight of solar panels, resist harsh outdoor environments, and directly affect the stability and service life of the entire photovoltaic project. As a professional manufacturer of roll forming equipment, our PV bracket roll forming machine integrates advanced cold roll forming technology, intelligent control systems, and durable structural design, dedicated to providing global photovoltaic manufacturers with high-efficiency, high-precision production solutions for PV brackets. Our machine is designed to produce various types of PV brackets, including roof-mounted brackets, ground-mounted brackets, and tracking system brackets, making it the preferred choice for solar energy projects worldwide.

Why Choose Our PV Bracket Roll Forming Machine?

Full-Automatic Production, High-Efficiency and Labor-Saving

The machine integrates the entire production process from raw material feeding to finished product output, including decoiling, leveling, servo precise feeding, hydraulic punching (for mounting holes, connecting holes), roll forming, fixed-length cutting, and automatic stacking, realizing one-stop fully automatic production. No manual intervention is required in the middle link, which greatly reduces labor intensity and avoids human errors caused by manual operation. Compared with traditional manual processing or semi-automatic production, the production efficiency is increased by 4-6 times, with a production speed of 12-30 m/min (adjustable according to material thickness and product specifications) and a maximum capacity of 180-220 bracket sections per hour. Only 1-2 operators are needed for a single shift to complete parameter setting and finished product inspection, significantly reducing labor costs and improving production efficiency.

High-Precision Molding, Stable Structural Performance

Precision and structural stability are the core advantages of our PV bracket roll forming machine. The forming rollers are made of high-quality Cr12MoV mold steel,经过 overall quenching and precision grinding treatment, with a hardness of HRC58-62, ensuring no scratches, indentations, or deformation on the surface of the formed bracket. The machine is equipped with Siemens or Mitsubishi PLC and touch screen control system, which realizes precise control of feeding length, forming angle, punching position, and cutting size, with a forming precision of ±0.3mm and a cutting precision of ±0.5mm. The formed PV bracket has a flat surface, accurate size, strong load-bearing capacity, and excellent structural stability, fully meeting international standards such as ASTM, EN, and IEC, and adapting to the long-term outdoor service requirements of photovoltaic projects.

Flexible Customization, Adapt to Diverse PV Project Requirements

Different photovoltaic projects (roof-mounted, ground-mounted, floating, tracking) have diverse requirements for the size, shape, and hole position of PV brackets. Our PV bracket roll forming machine supports full-range customization to meet your specific production needs. The machine can produce brackets of various specifications, with adjustable length (1000-6000mm), width (50-200mm), and thickness (1.2-3.0mm). The mold is designed with a quick-change structure, and the mold change time can be shortened to 8-12 minutes, realizing flexible switching between different types and specifications of PV brackets without replacing the entire mold set. In addition, the machine is compatible with multiple materials, including hot-dip galvanized steel, stainless steel, and aluminum alloy, which have excellent corrosion resistance and can adapt to harsh outdoor environments such as high temperature, humidity, and strong wind.

Stable Performance, Durable and Reliable

The main frame of the machine is welded with high-strength 45# H-type steel plate, and the whole frame is subjected to heat treatment to eliminate internal stress, ensuring strong rigidity, stable structure, and no deformation during long-term high-speed operation. Key components such as servo motor (Yaskawa), inverter (Mitsubishi), hydraulic pump (Bosch), and encoder (Omron) are all well-known international brands, ensuring the reliability and service life of the equipment (up to 100,000 working hours). The machine is equipped with complete safety protection devices, including emergency stop buttons, safety protective covers for transmission parts, and overload protection systems, fully guaranteeing the safety of operators and equipment during production. The machine has passed CE, ISO9001 certification, complying with international safety and quality standards, and can be smoothly exported to Europe, America, Southeast Asia, Africa, and other countries and regions.

Detailed Production Process

Decoiling & Leveling: The metal coil (hot-dip galvanized steel, stainless steel, etc.) is placed on the hydraulic uncoiler (load capacity up to 5t), which realizes motorized active decoiling. The 7-9 roller precision leveling device flattens the coil, ensuring that the raw material is flat, free of wrinkles, and has uniform thickness, laying a foundation for high-precision forming. The uncoiler supports a coil inner diameter of φ480-580mm and a maximum width of 500mm.

Servo Feeding: The Yaskawa servo feeder accurately feeds the leveled metal sheet into the next process, with a feeding width of up to 500mm and a feeding thickness of 1.2-3.0mm. The feeding length is precisely controlled by the PLC system, ensuring consistent feeding accuracy and avoiding size deviation of the PV bracket.

Hydraulic Punching: The hydraulic punching system with a working pressure of 20MPa completes the punching of mounting holes, connecting holes, and positioning holes according to the set parameters. The punching position and hole size can be freely adjusted through the touch screen, with high punching precision and efficiency. The hole type can be customized as round holes, oblong holes, or slot holes according to project needs.

Roll Forming: The metal sheet enters the 16-22 station roll forming machine through the guide device. The precision rollers gradually form the sheet into the required PV bracket shape, including edge folding, corner forming, and reinforcement rib forming. The added anti-scratch roller ensures that the surface of the bracket is smooth and free of defects, especially protecting the galvanized layer or coating from damage.

Fixed-Length Cutting & Edge Trimming: The hydraulic cutting device or fly-cut device (optional) cuts the formed continuous bracket to the set length, with a cutting tolerance of ≤±0.5mm. The edge trimming device trims the edges of the bracket to ensure neat edges and no burrs, improving the overall quality and safety of the product.

Finished Product Collection & Stacking: The finished PV brackets are automatically conveyed to the finished product rack, and the optional automatic stacker can stack the brackets into programmed numbers and layers, which is convenient for manual packaging, storage, and transportation, saving labor costs and improving production efficiency.
