I. Equipment Introduction
The solar PV mounting cold-roll forming machine is specialized equipment designed for the production of various PV mounting profiles. Utilizing a continuous cold-roll forming process, the machine transforms galvanized steel coils into finished PV mounting profiles in a single, integrated workflow—encompassing uncoiling and leveling, servo-driven feeding and punching, guided entry, roll forming, servo-tracking cutting, and stacking/unloading.
Designed specifically for galvanized steel strips with thicknesses ranging from 1 mm to 3 mm, a single unit can produce mounting profiles with side heights between 21 mm and 82 mm. The side ribbing function can be enabled or disabled based on customer requirements: enabling ribbing significantly enhances structural strength, making it ideal for long-span, high-load applications; disabling it is suitable for light-load projects where aesthetics are a priority. The entire line features fully automatic PLC control and supports one-touch specification switching, ensuring a continuous, automated process from uncoiling to finished product stacking. Requiring only 1–2 operators for monitoring, this equipment is essential for PV mounting manufacturers seeking to achieve flexible and intelligent production.
The machine is compatible with various materials, such as galvanized steel and Al-Zn coated steel, within a thickness range of 1.0–3.0 mm. It produces profiles with diverse cross-sections—including C-shapes and U-shapes—and is widely used in ground-mounted PV power plants, rooftop distributed PV systems, and agrivoltaic projects.
II. Core Advantages and Selling Points
1. One machine covers the full specification range (21–82mm) with one-touch switching
This is the core advantage distinguishing this equipment from conventional photovoltaic (PV) mounting production lines.
Conventional equipment requires manual roller adjustment or even mold replacement when changing specifications, resulting in long downtimes and complex operations. This machine utilizes adjustable forming technology, allowing a single unit to cover the entire specification range for side heights of 21–82mm—including mainstream PV mounting sizes such as 41×21, 41×41, 41×62, and 41×82. Specification switching is automated via a PLC-controlled motor system; operators simply input the target parameters on the touchscreen, and the roller positions adjust automatically. There is no need for mold changes, manual adjustments, or repeated trial runs. The switch takes just 3–5 minutes, significantly boosting production efficiency for orders involving multiple product varieties.
2. Flexible side-ribbing options, selectable on demand
The equipment features a side-ribbing function that can be enabled or disabled with a single touch based on customer requirements:
Ribbing enabled: Creates a reinforcing rib structure on the profile's side, significantly enhancing flexural strength and torsional rigidity. This is ideal for high-strength applications such as long-span mounts and installations in areas subject to high wind or heavy snow loads.
Ribbing disabled: Produces a profile with a smooth, flat surface and a clean, aesthetic appearance. This is suitable for light-load projects or distributed PV installations where visual appeal is a priority.
Two modes in one machine meet the diverse needs of different projects without requiring additional investment.
3. Integrated uncoiling and leveling for space and cost savings
The design integrates uncoiling and leveling into a single, compact unit. The leveling section employs multi-roller precision leveling to effectively eliminate internal stress in 1–3mm steel strips, ensuring accuracy in subsequent forming stages. The machine bed is constructed from welded steel plate and undergoes tempering to relieve internal stress and prevent structural deformation.
4. Servo feeding combined with punch press for precision and efficiency
A high-precision servo system ensures accurate feeding and positioning, while a punch press handles the punching of various features—such as mounting holes, connection holes, and interlocking teeth—with high efficiency. The process sequence of punching before forming allows for precise punching according to specifications prior to the forming stage, ensuring dimensional accuracy and high production efficiency. Servo-driven feeding ensures precise positioning, minimizes scrap, and effectively reduces material costs.
5. Multi-pass roll forming for superior quality
Utilizes a multi-pass progressive cold-roll forming process with precisely designed cross-sectional transitions. The layout of forming passes is scientifically optimized, accommodating a wide range of galvanized strip steel hardness levels while preventing damage to the zinc coating during rolling. The rollers are made of Cr12MoV steel, undergo integral quenching to achieve a hardness of HRC 56–62, and offer excellent wear resistance. High forming precision and consistency meet the demands of mass production.
6. Servo-tracking hydraulic cutting for continuous, non-stop operation
Employs a servo-tracking hydraulic cutting system that automatically matches the speed of the continuously moving profile to perform synchronized, fixed-length cutting. There is no need to slow down or stop the machine; the system ensures high cutting precision and clean, smooth edges. Spring-back at the cut opening is < 1 mm. Length dimensions are achieved in a single pass strictly within drawing tolerances, eliminating the need for secondary processing.
7. Automated palletizing for organized output
Equipped with an automatic palletizing system; finished profiles are conveyed automatically to the palletizing station. Stacking is performed automatically according to preset programs, ensuring neat and orderly arrangement. Manual handling is eliminated, significantly reducing labor intensity.
8. Cold-roll forming: Cost reduction and efficiency gains
Replacing hot stamping with cold-roll forming reduces equipment investment costs by approximately 30%. Cold-roll forming eliminates the need for heating equipment and complex temperature control systems, resulting in lower energy consumption. Additionally, the process takes place at ambient temperature; the absence of excessive heat prevents oxidation and material quality loss.
9. Intelligent control for ease of operation
Features fully automated PLC control and a touchscreen HMI for intuitive, convenient parameter setting. The entire line—from uncoiling to palletizing—is automated, requiring only 1–2 operators for monitoring. Automatic fault diagnosis and alarm functions facilitate rapid troubleshooting and maintenance.
