This spiral rebar bender tackles the demanding task of shaping straight steel bars into precise spiral or circular reinforcement forms. With accuracy to ±0.2 mm and bending speeds reaching 30 m/min, it transforms straight stock into high-quality coils at scale. Kick-off efficiency, slash labour time, minimise variation.
What is the Spiral Rebar Bender?
A spiral rebar bender is a specialised machine used in concrete reinforcement works. It bends rebars into circular or helical shapes — essential for applications such as pile cages, tunnel hoops, high-speed rail anchors, or prefabricated rings. Equipped with CNC input and hydraulic drive, the machine automates feed-bend-cut operations and handles a range of diameters from small hoops to large spirals.
Key Benefits of Our Rebar Circle Making Machine
For businesses looking to invest in a reliable and powerful steel bar hoop bender, the Shuliy model stands out. Our Fully Automatic CNC Five-Head Slab Bar Bending Machine is engineered for high-volume, high-precision work, making it the ideal choice for demanding projects.
- Automated CNC control: set hoop diameter, coil pitch, and batch quantity once; let it run.
- High precision output: consistent shape and size across large runs; reduces scrap.
- Rapid production rate: suitable for high-volume fabrication plants or demanding job sites.
- Robust hydraulic system: strong bending force, stable performance under heavy load.
- Wide material compatibility: supports multiple bar diameters, various reinforcement grades.
How the Rebar Ring Bender Works?
Once parameters are programmed, the system’s PLC activates the motor and hydraulic pump. The steel bar is straightened, fed into the rounding assembly, bent into the preset spiral or circle, and cut automatically. One smooth cycle: feed → bend → cut. This continuous loop ensures minimal manual intervention and high output consistency.
