Automatic Feeding 8-Wheel CNC Rebar Bender for 16mm Threaded Steel Bar

16mm threaded steel bar (rebar) is one of the most widely used reinforcing materials in modern construction, covering residential and commercial buildings, bridge infrastructure, precast concrete components, and road engineering. Traditional manual and semi-automatic bending equipment often struggles with unstable feeding, thread surface damage, bending angle deviation, and low efficiency when handling this standard-sized rebar, directly affecting construction progress and project quality.

Haihui’s Automatic Feeding 8-Wheel CNC Rebar Bender for 16mm Threaded Steel Bar is a fully upgraded, purpose-built processing machine designed to solve these industry pain points. It integrates intelligent CNC control, stable 8-wheel traction, and fully automatic feeding functions, exclusively optimized for 16mm threaded rebar, realizing fully automated, high-precision, and high-efficiency one-stop bending processing. With a sturdy structure, user-friendly operation, and long-lasting durability, this machine has become the preferred choice for construction sites, professional rebar processing centers, and precast component factories worldwide.

2. Core Advantages: Built for Stable, Efficient, and Precise Bending

2.1 Fully Automatic Feeding: Zero Manual Handling, Boost Efficiency

Equipped with a dedicated automatic feeding system, this machine eliminates the need for manual rebar pushing and positioning, a common hassle with standard bending machines. Operators only need to place 16mm threaded steel bars at the designated feeding port, and the system automatically conveys, positions, and feeds the rebar steadily throughout the process. This fully automated workflow cuts labor intensity by over 70%, and a single operator can easily manage 2-3 machines simultaneously, greatly increasing daily processing output and reducing overall labor costs for construction and processing teams.

2.2 8-Wheel Traction System: No Slip, No Thread Damage

The unique 8-wheel symmetric traction structure is the core highlight of this machine, specially engineered for 16mm threaded rebar. Unlike traditional 4-wheel or 6-wheel traction models, the 8 groups of heat-treated high-strength alloy wheels distribute clamping force evenly, matching the ribbed surface of threaded steel bars perfectly. This design ensures completely non-slip conveying, avoids jamming, and prevents scratches or wear to the rebar threads during feeding—critical for maintaining the structural performance and bonding strength of threaded rebar in construction. Even under long-hour, high-load continuous operation, the traction stability remains consistent, laying a solid foundation for accurate bending.

2.3 Intelligent CNC Control: One-Click Operation, Ultra-High Precision

The machine is fitted with an intuitive CNC digital control panel with a clear digital display and simple button operation, making it easy to master for both new and experienced operators. Users can preset core parameters including bending angle, fixed length, bending quantity, and processing speed according to actual construction requirements. The system supports storing 20+ groups of custom bending programs, suitable for common stirrup shapes such as rectangular, square, U-shaped, and polygonal, enabling quick program switching without repeated manual adjustment.

Bending precision is strictly controlled within ±0.5°, fully meeting international and domestic construction standards for rebar processing. Every formed component maintains consistent size and angle, minimizing rework and material waste, and fully complying with the high-quality requirements of modern engineering projects.

2.4 Heavy-Duty Durable Design: Adapt to Harsh Work Environments

The entire machine adopts a thickened steel plate welded frame with reinforced structural design, featuring excellent rigidity and shock resistance, no deformation after long-term use, and adaptability to various harsh construction site conditions. Core wearing parts such as traction wheels, bending shafts, and forming modules are made of wear-resistant alloy steel through special heat treatment, with a service life far exceeding ordinary parts, reducing the frequency of replacement and later maintenance costs. It also comes with a fault self-diagnosis function, which automatically alarms and displays clear fault codes for abnormalities like motor overload and parameter errors, making troubleshooting fast and convenient.

4. Wide Application Scenarios

• Construction Sites: High-rise residential buildings, commercial complexes, industrial workshops, for rapid on-site processing of 16mm threaded rebar stirrups and shaped components;

• Infrastructure Engineering: Bridges, highways, railways, tunnels, and water conservancy projects, meeting high-precision and large-volume rebar bending demands;

• Precast Concrete Factories: Batch production of standardized rebar components, ensuring consistent quality and efficient delivery;

• Rebar Processing Distribution Centers: Centralized large-scale processing, reducing comprehensive operating costs and improving delivery efficiency.

5. Safe Operation & Usage Notes

1. Before operation, check the power supply, traction wheels, and bending parts to ensure no loose components or abnormal noise; 2. Do not adjust parameters or touch the working area during machine operation to avoid safety risks; 3. Regularly lubricate moving parts and clean up rebar scraps to keep the machine in optimal condition; 4. For 16mm threaded steel bars, avoid mixing with over-sized or damaged bars to prevent machine jamming; 5. Operators must receive simple training before formal use to master parameter setting and emergency stop operations.
