CD keel forming machine is a specialized cold bending forming equipment for light steel building ceilings/partitions. It is designed to roll galvanized coils and cold-rolled coils into CD series ceiling main keels (50/60/75/100 types) at once, and is matched with UD/UC keels to form a light steel keel system. It is widely used in building decoration, partitions, ceilings, and prefabricated houses. The equipment has a high degree of automation, precise molding, and stable operation, making it the core equipment of the light steel keel production line.

Equipment structure composition

• Manual/Hydraulic Uncoiler: 3-5 ton load capacity, compatible with standard coils, smooth feeding without deviation.
• Leveling guide frame: Multi roller leveling ensures the flatness of the board and precise feeding.
• Forming host: 12-18 rows of precision rolling mill progressive rolling, eliminating internal stress, with standard keel size and good straightness.
• Hydraulic punching unit (optional): capable of punching installation holes and connection slots, with precise positioning and smooth hole positions.
• Hydraulic flying shear cutting: Cr12MoV quenched cutting tool, dynamic cutting without stopping, high efficiency, and no burrs on the cut.
• PLC intelligent control system: Siemens/Delta PLC+touch screen, parameter memory, fault alarm, production statistics, one click fully automatic production.
• Discharge rack+stacking rack: anti scratch design, automatic stacking, saving labor.
• Automatic lubrication system: timed and quantitative oil supply, reducing roll wear and extending equipment life.

Performance advantages

• Precision molding: The rolling mill is precision machined with a dimensional error of ≤± 0.1mm, and the keel has good straightness and tight splicing.
• Efficient and high-yield: Automated assembly line, daily production capacity of 2000-5000 meters, continuous operation without faults, efficiency 5 times higher than traditional manual labor.
• Stable and durable: The core components have undergone quenching treatment, resulting in strong rigidity and a service life of over 8 years, with a low failure rate.
• Easy to operate: Intelligent PLC system, one click parameter calling, single person operation, beginners can get started in 30 minutes.
• Flexible customization: The specifications, hole positions, and lengths of the keel can be customized to meet different decoration/construction needs.
• High cost-effectiveness: low energy consumption, simple maintenance, universal accessories, and low long-term usage costs.
