- The machine offers accurate arc formation and efficient bending processes.
- Equipped with features like a nine-wheel CNC bending turbine reducer and a high-strength working wheel for durability.
- Robust Design:
- Uses a double driving wheel transmission structure for stable and reliable performance.
- Lubrication with calcium-based grease for ease of maintenance and longevity.
- Intelligent Storage and Retrieval:
- Can store up to 99 different bending graphics in its computer memory for quick retrieval and use.
Equipment Parameter
- Power and Motor:
- Nine-wheel CNC bending turbine reducer.
- 4-kilowatt walking motor.
- CNC servo motor with planetary reducer for the arc pusher.
- Control System:
- Computer touch screen for user-friendly operation.
- PLC programming for precise control.
- Bending Capabilities:
- Suitable for 14-32mm rebar.
- Can execute 10 different straight lines, angles, and arcs on a single bar.
Safety Operation Procedure
- Setup and Adjustment:
- Ensure bolts and machine settings are secure to prevent hazards.
- Confirm motor rotation direction matches the indicated arrow before starting.
- Operation:
- Insert the material into the working slots and adjust the wheel for the desired arc size.
- Perform trial bends to fine-tune the adjustment.
- Maintenance:
- Immediately stop and check the machine if a problem occurs.
- Always cut off power before performing any maintenance.
- Limit Adjustments:
- Adjust the limit bolt to fine-tune the arc size.
- Tighten the nut after adjustments and proceed with operations.
- Bending Process:
- For smaller diameter arcs, release and then press the material before starting the working wheel.
- For larger diameter arcs, start the working wheel first and then feed the material directly.
Summary
GHM Machinery’s tunnel steel bar arc bending machine offer a combination of precision, efficiency, and versatility, making them ideal for various construction applications. With advanced CNC control, user-friendly operation, and robust safety features, these machines enhance productivity and ensure high-quality bending of steel bars for complex construction projects.
