The machine uses PLC control and hydraulic drive to provide stable operation and accurate circle forming. The model can be set in batches and can automatically process a bundle of steel bars in one continuous operation.
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.
The rebar circle making machine is designed for processing steel bars into circles and spirals for the following applications:
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.
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, 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 supports batch processing and can automatically process a bundle of steel bars continuously, improving production efficiency and reducing manual labor.
The rebar circle making machine consists of the following main components:
The machine adopts a CNC electrical control system with PLC control. After setting the parameters, the machine can automatically process a bundle of steel bars without manual intervention, greatly improving production efficiency.
The machine uses a hydraulic drive system including an oil pump, hydraulic motor, and electronic valves. This provides stable operation, strong power output, and accurate control of the circle forming process.
The rounding assembly is designed to provide accurate circle forming with a working error of only ±0.2mm, ensuring consistent product quality across batch production.
The machine can be set up in batches and can automatically process a bundle of steel bars in one continuous operation. This reduces manual labor and improves production consistency.
With 6 available models covering steel bar diameters from 3mm to 25mm, the machine can meet various processing requirements from small spring coils to large-diameter structural rings.
The machine is designed for processing ground pile anchors for high-speed railway, subway, photovoltaic power, and other engineering projects, making it a versatile solution for different construction applications.
