The CNC Steel Bar Straightening and Bending Machine is a core fully automatic steel bar processing equipment integrated with a PLC intelligent control system. It is specially designed for scenarios such as construction projects, bridge infrastructure, and prefabricated component factories, enabling integrated full-process operations including steel bar straightening, fixed-length cutting, and precise bending. This equipment completely replaces the traditional manual segmented processing mode. After parameter setting is completed via the high-definition touch operation screen, it can automatically run the entire process from coiled bar feeding to formed stirrup production, effectively solving the core pain points of low efficiency, large precision deviation, and high labor cost in traditional processing. The machine body is formed by integral welding of thickened steel plates, featuring a sturdy and earthquake-resistant structure. Equipped with well-known brand servo motors and straightening components, it has a service life of 8-10 years and is suitable for processing various materials such as smooth round steel and deformed steel bars within the range of Φ5-Φ16mm. It is an essential equipment for improving quality and efficiency in modern steel bar processing workshops.

Core Advantages
Efficient Integration and Leap in Production Capacity: The equipment integrates three core functions of straightening, bending, and cutting, eliminating the time loss of process transfer in traditional processing and realizing uninterrupted continuous production.
Millimeter-level Precision and Controllable Quality: Adopting an imported PLC numerical control system for real-time closed-loop control, the straightening process eliminates steel bar stress through multi-round precision calibration technology. The bending angle is accurately driven by a servo motor, with an error controlled within ±0.5°, and the fixed-length precision of steel bar length reaches ±1mm.
Stability, Safety, and Convenient Operation & Maintenance: The machine body adopts an integral welded frame structure, which can adapt to 24-hour high-intensity operations.
Flexible Adaptation and Intelligent Convenience: It is suitable for various types of steel bars, supports arbitrary angle bending processing from 0° to 180°, and has built-in more than 100 common steel bar processing graphic templates.
Working Principle
Feeding Preparation: Fix the coiled steel bar on the pay-off rack, and feed the end of the steel bar into the main machine through the guiding mechanism.
Precision Straightening: Multiple sets of straightening wheels cooperate with the PLC system to continuously straighten the steel bar, and real-time detection and elimination of steel bar bending stress are carried out.
Parameter Setting: Input processing parameters such as steel bar length, bending angle, and number of bends through the touch screen, and the system automatically generates the processing program.
Synchronous Bending and Cutting: The servo motor drives the bending mechanism to complete the bending action according to the program, and at the same time, the hydraulic cutting knife accurately cuts the steel bar to ensure dimensional accuracy.
Finished Product Output: The processed steel bars automatically fall into the collection rack, and the entire process realizes fully automatic operation without manual intervention in intermediate links.
