Core Advantages: Stability, Efficiency & Precision for 16mm Rebar

Auto Feeding System: Hands-Free Operation, Maximized Efficiency

This machine is equipped with a dedicated full auto feeding mechanism, eliminating the need for manual rebar pushing, positioning and adjustment that plagues standard bending equipment. Operators simply place 16mm rebar at the designated feeding port, and the system automatically completes stable conveying, precise positioning and consistent feeding throughout the entire processing cycle. This fully automated workflow reduces manual labor intensity by more than 70%, and a single operator can easily manage 2 to 3 machines at the same time, significantly boosting daily processing output and cutting overall labor costs for construction and rebar fabrication teams.

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.

8-Wheel Traction System: Non-Slip Conveying, No Rebar Damage

The patented 8-wheel symmetric traction system is the core highlight of this Haihui rebar bender, specially engineered for 16mm rebar. Unlike standard 4-wheel or 6-wheel traction models, the 8 groups of heat-treated high-strength alloy wheels distribute clamping force evenly, perfectly matching the ribbed surface of rebar to avoid slipping, jamming or surface scratches during feeding. This design is critical to preserving the structural integrity and bonding strength of 16mm rebar, ensuring no material waste from damaged steel bars. Even during long-hour, high-load continuous operation, the traction system maintains stable performance, laying a solid foundation for consistent, accurate bending results.

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.

Intelligent CNC Control: Simple Operation, Ultra-High Precision

The machine features an intuitive CNC digital control panel with a clear display and user-friendly button layout, easy to operate for both new and experienced staff. Operators can preset core parameters including bending angle, fixed cutting length, processing quantity and speed based on actual project needs. The system supports storing over 20 custom bending programs, compatible with common stirrup shapes such as rectangular, square, U-shaped and polygonal, allowing quick program switching without repeated manual adjustment.

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