GHM Machinery’s tunnel steel bar bending machines are advanced equipment designed for precise and efficient bending of steel bars used in various construction applications, particularly in tunnels, culverts, hydropower stations, subways, and beam yards. These machines can handle multiple bending tasks, including forming complex shapes and varying the bending radius on a single steel bar.
Key Functions and Features
- Multi-Radius Forming:
- The machines can perform multi-radius forming in one operation, bending steel bars into various angles, curves, and straight lines.
- Capable of creating up to 10 different radii or angles on a single steel bar.
- CNC Control and Display Screen Operation:
- Controlled via CNC (Computer Numerical Control) for precise operations.
- Display screen allows for easy programming and adjustment of bending parameters.
- Versatility:
- Suitable for bending steel bars with diameters ranging from 14 to 32 mm.
- Can handle variable diameter bending and 360° arc forming.
- High Precision and Efficiency:
- 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 Parameters
- 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 Procedures
- 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 bending machines 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.
