Equipment Overview
The CU Opening and Closing Light Steel Keel Roll Forming Machine is a highly flexible cold-bending forming production equipment specifically designed for manufacturing C-shaped and U-shaped light steel keels for building partitions, ceiling systems, and prefabricated buildings. This equipment optimizes the structure of the traditional CU-type light steel keel machine, achieving rapid switching between different specifications of C-shaped and U-shaped keels through an openable forming frame design, significantly reducing changeover time and improving overall equipment utilization.
Light steel keel is a lightweight, thin-walled steel structure profile made primarily from continuous hot-dip galvanized steel strip through a continuous cold-bending forming process. Due to its advantages such as light weight, high strength, fire resistance, moisture resistance, corrosion resistance, and convenient installation, it is widely used in modern building interior systems.
The CU openable light steel keel machine adopts a modular openable forming structure. The spacing between the forming rollers is changed through mechanical adjustment, allowing the equipment to adapt to the production of keel products with different widths, heights, and cross-sectional structures. Compared to traditional fixed light steel keel equipment, this machine eliminates the need for frequent roll disassembly, enabling rapid conversion between different product specifications and effectively improving production flexibility.
The entire line consists of hydraulic uncoiling, guiding feeding, leveling and straightening, a punching system, openable roll forming, length cutting, and an automatic material collection system. The equipment utilizes a PLC automatic control system to achieve automatic adjustment of production parameters and full-process digital management.
The CU openable light steel keel machine is suitable for galvanized steel strips with a thickness of 0.35- 1.5 mm and can produce various specifications of C-shaped keels, U-shaped top and bottom keels, and special structural light steel profiles. It is particularly suitable for light steel keel manufacturers with diverse product specifications, frequent order changes, and a need for rapid product changeover.
Core Advantages and Selling Points
Opening/Closing Forming Structure for Quick Switching Between Specifications
The biggest feature of the CU opening/closing light steel keel machine is its opening/closing forming frame design. By adjusting the distance between the forming rollers, different specifications of keel products can be quickly switched.
Traditional light steel keel production equipment is usually designed for a single specification. Changing products requires disassembling a large number of rollers, which is not only time-consuming but also affects production efficiency.
Advantages of the opening/closing structure: No need to frequently change the entire set of rollers; reduced equipment adjustment time; improved production line utilization; adaptable to multi-variety order production; reduced equipment investment costs; particularly suitable for building material companies to produce multiple specifications of keel products simultaneously.
C/U Dual-Mode Production: One machine covers multiple building profiles. Through optimized roller design, the equipment can quickly switch between C-shaped and U-shaped keels.
Production scope includes: C-shaped vertical keels, U-shaped ceiling and ceiling keels, partition wall system keels, ceiling load-bearing keels, decorative system auxiliary profiles. A single production line can meet the needs of different construction projects, improving equipment utilization efficiency.
Precision multi-pass cold bending ensures profile quality. The equipment employs a progressive multi-pass cold bending process, allowing the steel strip to deform gradually at multiple forming stations.
Compared to single-pass bending, multi-pass forming reduces internal material stress, minimizes product springback, improves cross-sectional accuracy, ensures product straightness, enhances installation compatibility, and guarantees dimensional stability and structural robustness of the produced light steel keel.
High-rigidity frame design is suitable for long-term continuous production. The main body of the equipment utilizes a high-strength frame structure, improving overall rigidity and operational stability.
During high-speed production, the high-rigidity structure effectively reduces equipment vibration, ensuring precise roller alignment.
Equipment advantages: smoother operation, more uniform forming pressure, longer equipment lifespan, lower maintenance costs, and meeting the continuous production needs of large-scale light steel keel factories.
The online punching system enhances product added value. The equipment can be configured with an automatic punching device according to customer requirements, enabling online processing of keel holes.
The punching system can be customized according to product specifications: hole spacing, hole type, hole position, and punching quantity. Online punching reduces subsequent processing steps, improves product standardization, and facilitates rapid on-site installation.
The high-precision roll system protects the galvanized layer quality. The forming rolls are made of high-quality mold steel and undergo heat treatment to improve wear resistance and service life.
The precision roll design ensures a smooth profile surface, an undamaged galvanized layer, stable cross-sectional dimensions, and maintained high precision over long-term production, making it suitable for large-volume, high-quality light steel keel production.
PLC intelligent control ensures simple and convenient operation. The equipment adopts a PLC automatic control system equipped with a touch screen human-machine interface, realizing intelligent management of the production process.
Operators can control in real time: production speed, product length, changeover parameters, equipment status, alarm information. Automated control reduces manual labor requirements; normal production requires only 1-2 people to operate.
High-efficiency production meets the market's demand for rapid delivery. The CU opening and closing type light steel keel machine adopts a continuous production mode, which is more efficient than traditional processing methods.
The equipment is capable of continuous processing of steel coils, rapid adjustment of specifications, reduced downtime, and improved order response speed. It is suitable for building material suppliers, large-scale keel manufacturers, and export-oriented building material manufacturers.
