This product details will elaborate on the machine’s structure, working principle, core components, operation steps, maintenance methods and other key information to help you fully understand the equipment.
1. Machine Overall Structure
The machine is composed of 6 core parts, each of which cooperates closely to ensure the smooth operation of the entire production line. The structure is compact, the layout is reasonable, and it is easy to install and maintain.
- Feeding Device: It consists of a coil support frame, a feeding roller and a guide device. The coil support frame adopts a hydraulic lifting structure, which can easily load steel coils with a weight of 1-5 tons, and the feeding roller is covered with anti-slip rubber to prevent the steel coil from slipping during feeding. The guide device ensures that the steel coil enters the leveling device smoothly and avoids deviation.
- Leveling Device: Equipped with 7-9 groups of leveling rollers made of high-quality alloy steel, which are precisely ground and heat-treated. It can effectively eliminate the internal stress of the steel coil, correct the deformation of the steel plate, and ensure that the steel plate is flat before forming, laying a foundation for precise forming.
- Punching Device: Optional automatic punching module, equipped with a hydraulic punching head and a replaceable die. It can punch holes of different sizes and shapes (round holes, square holes) at the specified position of the steel plate according to the needs of the project, with high punching precision (±0.5mm) and fast speed, which can be synchronized with the forming process without affecting production efficiency.
- Forming Device: The core part of the machine, composed of 12-16 groups of forming rollers. The rollers are designed with a scientific multi-pass progressive forming structure, which gradually bends the flat steel plate into a C-shaped cross-section. The roller surface is chrome-plated, which has strong wear resistance and corrosion resistance, and can ensure the smooth surface of the formed purlin without scratches.
- Cutting Device: Adopts hydraulic cold cutting technology, with a high-hardness cutting blade. It can cut the formed C-type purlin according to the set length, with smooth cutting surface, no burrs, no deformation, and the cutting length error is controlled within ±1mm. The cutting process is fast and stable, and can be automatically triggered after the purlin reaches the set length.
- Discharging Device: Equipped with a conveying roller and a receiving frame, which can automatically convey the cut C-type purlins to the receiving area, avoiding manual handling, reducing labor intensity, and ensuring the orderliness of the finished products.
2. Working Principle
The working process of the C-Type Purlin Forming Machine is fully automatic, and the whole process is controlled by the PLC system, which is simple and efficient. The specific working principle is as follows:
- First, place the cold-rolled steel coil on the coil support frame, and adjust the height and position of the coil to align with the feeding device.
- Start the machine, the feeding roller drives the steel coil to enter the leveling device, and the leveling rollers correct the steel plate to make it flat.
- The flat steel plate enters the punching device (if equipped), and the hydraulic punching head punches holes at the set position according to the pre-set parameters.
- The steel plate after punching enters the forming device, and the multi-group forming rollers gradually bend the steel plate into a C-shaped cross-section through progressive forming.
- When the formed C-type purlin reaches the set length, the cutting device is automatically triggered to cut the purlin, and the cut purlin is conveyed to the receiving frame through the discharging device.
- The machine repeats the above steps to realize continuous mass production, and the production process can be monitored in real time through the touch screen, and parameters can be adjusted at any time if necessary.

Advantages of Roll Forming A Metal Part
There are several advantages of using roll forming for your projects:
- The roll forming process allows operations such as punching, notching, and welding to be performed in-line. Labor cost and time for secondary operations are reduced or eliminated, reducing part costs.
- Roll form tooling allows for a high degree of flexibility. A single set of roll form tools will make almost any length of the same cross-section. Multiple sets of tools for varying length parts are not required.
- It can provide better dimensional control than other competing metal forming processes.
- Repeatability is inherent in the process, allowing easier assembly of roll formed parts into your finished product, and minimizing problems due to “standard” tolerance build up.
- Roll forming is typically a higher speed process.
- Roll forming offers customers a superior surface finish. This makes roll forming an excellent option for decorative stainless steel parts or for parts requiring a finish such as anodizing or powder coating. Also, texture or pattern can be rolled into the surface during forming.
- Roll forming utilizes material more efficiently than other competing processes.
- Roll formed shapes can be developed with thinner walls than competing processes
Roll forming is a continuous process which converts sheet metal into an engineered shape using consecutive sets of mated rolls, each of which makes only incremental changes in the form. The sum of these small changes in form is a complex profile.
