Working Principle
Power transmission: After the equipment is connected to the power supply, the motor converts electrical energy into mechanical energy and transmits power to each bending head through transmission devices such as belts, chains, or gears. The motor's power and performance directly affect the output and operational stability of the equipment. High-quality motors ensure stable operation under long-term, high-intensity work.
Numerical control system: On the CNC operation interface, the operator inputs parameters such as diameter, bending angle, and bending shape of the bars. After receiving instructions, the CNC system precisely controls the motor speed, rotation direction, and movement position of each bending head through internal program operations. For example, when bending U-shaped bars, the system controls two opposite heads to rotate synchronously at a set angle, while the middle head assists in positioning to ensure the required bending shape.
Bending actuator: Each bending head is equipped with a bending die and a pressing device. Once the bars are positioned, the clamping device quickly secures them to prevent shifting during bending. The bending die then performs the operation according to the CNC instructions. The material and precision of the die are crucial to bending quality. High-quality dies ensure smooth bends free of cracks, deformation, or other defects.
Performance Advantages
High-precision processing: The machine uses advanced servo control systems, achieving extremely high accuracy in both angle and length. Angle accuracy reaches ±1°, and length accuracy ±2mm, meeting the strict requirements of complex building structures. In large bridges and high-rise buildings, this ensures precise installation and enhances structural stability and safety.
Multi-functional processing: The equipment can bend bars into a wide range of shapes, from common right-angle and obtuse bends to U-shaped and multi-arc bars. With a built-in graphics database, operators can retrieve commonly used shapes without complex programming. Parameters can also be adjusted to meet project-specific needs, enabling customized processing.
Easy operation: Equipped with a PLC and touch screen interface, the system is simple and intuitive. Even less experienced operators can learn quickly after short training. High automation reduces manual intervention, lowers labor intensity, and improves safety.
Application Scenarios
High-rise construction: Processes bars for beams, slabs, and columns, ensuring structural stability.
Residential communities: Meets mass production requirements for standardized designs, improving efficiency and shortening construction time.
Infrastructure construction: Used in highway and high-speed railway bridges, as well as subway stations and tunnels, where high precision and efficiency are essential.
Large-scale bridges: Produces complex prestressed bars and special stirrups, meeting strict structural requirements and ensuring durability.
Prefabricated buildings: Enables precise, standardized mass production of bars for prefabricated components, improving efficiency and quality.
Key Points of Operation
Equipment commissioning: For first-time use or specification changes, debug the equipment. Check head movement, adjust die spacing, and verify CNC input parameters through trial runs.
Steel bar feeding: Load bars within capacity, place them neatly, and align them with the die axis. For long bars, use auxiliary supports to prevent sagging.
Parameter setting: Accurately input diameter, bending angle, radius, and shape. For complex shapes, convert design drawings into instructions. Carefully check inputs to avoid errors and waste.
Safe operation: Never bring hands or body parts near bending heads or the conveying area. Wear protective gear such as helmets, gloves, and goggles. Regularly check safety devices like emergency stops and protective covers to ensure safe operation.
