Performance Characteristics
Features a "Weishi" brand housing for robust construction.Equipped with a high-quality, ultra-quiet gearbox for stable operation.Incorporates a thickened worm shaft and enlarged worm wheel to increase gear contact area, delivering more powerful performance.Components made from heat-treated 45# steel.Includes a carburized baffle (jack-type design) and an external gear grease recycling cover for convenient and quick maintenance.
Core Advantages
The GW40 Steel Bar Bending Machine is engineered to handle rebar from 6mm to 40mm in diameter, supporting common bending shapes such as 90°, 135°, and 180° bends, as well as custom angles. It features a robust cast iron frame and high-torque motor, ensuring stable performance even under continuous heavy-duty use.
High Precision
The rotating bending disc and adjustable positioning pins ensure consistent bend angles with minimal error, meeting construction industry standards.
01
Durable Construction
The machine's key components-gears, bearings, and bending pins-are made of high-strength steel and heat-treated for wear resistance, extending service life.
02
User-Friendly Operation
The intuitive control panel with adjustable speed settings allows operators to set parameters quickly, reducing setup time and improving productivity.
03
Versatile Applications
Ideal for bending round bars, deformed bars, and rebar in construction projects, bridges, highways, and precast concrete production.

Common Faults & Quick Solutions
| Symptom | Possible Cause | Troubleshooting & Repair |
|---|---|---|
| Motor does not start |
1. Power supply failure or loose connections 2. Blown fuse or faulty circuit breaker 3. Overload protection triggered |
1. Check power cable connections and voltage 2. Replace the fuse and reset the circuit breaker 3. Reduce load, wait for cooling, and restart |
| Bending disc does not rotate |
1. Broken V-belt 2. Worn gear or bearing 3. Motor shaft failure |
1. Replace the V-belt and adjust tension 2. Lubricate or replace worn gears/bearings 3. Inspect motor shaft and repair/replace if damaged |
| Inaccurate bending angle |
1. Worn positioning pins 2. Loose disc fasteners 3. Uneven machine placement |
1. Replace worn pins with new ones 2. Tighten the disc bolts securely 3. Level the machine on a flat, stable surface |
| Abnormal noise during operation |
1. Lack of lubrication in gears/bearings 2. Loose fasteners 3. Debris stuck in the mechanism |
1. Add gear oil and grease bearings regularly 2. Tighten all bolts and fasteners 3. Clean debris from the working area |
| Motor overheats quickly |
1. Overload operation 2. Poor ventilation around the machine 3. Low voltage supply |
1. Avoid continuous operation at maximum load 2. Ensure proper ventilation and clean the motor cooling fan 3. Check power supply and use a voltage stabilizer if needed |
