What Is a Rebar Circle Making Machine?
The rebar circle making machine, also known as a spiral rebar forming machine or spring coiling machine, is a CNC automatic equipment specially designed for bending steel bars into circular shapes.
The machine uses a hydraulic system to drive the straightening gearbox, rounding assembly, and cutting assembly to complete the circle forming process. During operation, the steel bar is fed forward, moved to the rounding assembly to complete the circle forming, and then cut off automatically.
With 6 available models covering steel bar diameters from 3mm to 25mm and finished ring diameters from 50mm to 3000mm, the machine can handle different processing requirements across various construction and engineering projects.
Suitable Processing Applications
The rebar circle making machine is designed for processing steel bars into circles and spirals for the following applications:
- Ground pile anchors for high-speed railway and subway construction
- Spiral reinforcement for photovoltaic power projects
- Spring coils for various industrial applications
- Circular reinforcement rings for concrete piles and columns
- Spiral steel bars for bridge and road construction
- Ring-shaped steel components for foundation engineering
Typical Production Process
The typical production process using the rebar circle making machine is as follows:
Steel Bar Feeding → Pre-adjusting → Straightening → Circle Forming → Automatic Cutting → Finished Ring Output
The entire process is controlled by the CNC system and can operate continuously for batch processing.
How Does the Rebar Circle Making Machine Work?
The operation process of the rebar circle making machine includes the following steps:
Step 1 – Machine Startup: The PLC motherboard controls the motor to drive the oil pump, starting the hydraulic system and preparing the machine for operation.
Step 2 – Straightening and Feeding: The hydraulic system drives the straightening gearbox to operate, which straightens the steel bar and moves the material forward into the rounding assembly.
Step 3 – Circle Forming: The steel bar is moved to the rounding assembly, where it is bent into the desired circular shape according to the preset diameter settings.
Step 4 – Automatic Cutting: After the circle forming is completed, the cutting oil cylinder cuts the material upward, separating the finished ring from the remaining steel bar.
Step 5 – Batch Processing: This model can be set in batches and can automatically process a bundle of steel bars continuously, improving production efficiency and reducing manual labor.
Composition and Structure
The rebar circle making machine consists of the following main components:
- Electric motor – provides the power source for the entire machine
- Hydraulic components – include an oil pump, hydraulic motor, electronic valve, oil tank, and oil pipes
- Pre-adjusting wheel – pre-adjusts the steel bar before straightening
- Straightening gearbox – straightens and feeds the steel bar forward
- Rounding assembly – forms the steel bar into the desired circular shape
- Cutting assembly – automatically cuts the finished ring from the steel bar
- CNC electrical control program – controls the entire operation through PLC
