Rebar Spiral Forming Machine is designed to offer a semi-automatic solution for winding flat workpieces into spiral bars efficiently. It features a rotary forming structure, ensuring convenience and speed in the winding process, thus saving time and effort while enhancing processing efficiency.
Rebar Spiral Forming Machine comprises a workbench with a semicircular track, along which a rotating shaft moves. The shaft is encased with a sleeve, and there’s a fixed shaft at the center of the track. A pitch forming plate is positioned between the fixed shaft and the track, with a feed plate on one side of the fixed shaft. A guide hole on the feed plate facilitates the winding process by aligning with the pitch forming plate and the track.
Furthermore, the spiral bar forming machine integrates a steel bar straightening module, consisting of intersecting straightening wheels with grooves for steel bars. The steel bar conveying module, on the other hand, comprises conveying wheels arranged vertically. An arc guide wheel marks one end of this module, with a steel bar discharging guide port positioned between the conveying module and the arc guide wheel.
This structure ensures the machine’s durability and longevity, making it a highly efficient tool for spiral bar formation.

Spiral Bar Forming Machine Operating Procedures and Matters Needing Attention
Ensure Mechanical Performance
Verify the workbench and bending machine table are level, and secure various mandrel tools in place.
Proper Installation
Install the mandrel, forming shaft, iron stop shaft, or variable stop frame according to steel bar diameter and hoop bending machine requirements. Mandrel diameter should be 2.5 times the steel bar diameter.
Inspect Equipment
Check mandrel, block, and turntable of the steel hoop bending machine for damage or cracks. Secure protective covers firmly. Only operate the machine after running it empty.
Safe Operation
Insert the steel bar end needing bending into the turntable gap, secure the other end, and press tightly by hand. Ensure the machine is fixed and positioned correctly before starting.
Strict Prohibitions
During operation, do not replace mandrels, change angles, adjust speeds, or refuel.
Adhere to Specifications
Do not process steel bars exceeding specified diameter, quantity, or mechanical speed during bending.
Handle High Hardness Steel
When bending high hardness or low alloy steel bars, adjust diameter according to mechanical nameplate and replace mandrel accordingly.
Safety Measures
Do not stand within the working radius of the steel spiral bending machine, ensure the machine body has a fixed side. Stack bent semi-finished products neatly, avoiding upward-facing hooks.
Directional Changes
Only change turntable direction after it has completely stopped.
Post-Operation Cleanup
After completing steel spiral bending machine operation, clean the site, machinery, and ensure power-off and lock the box.
