Operating Procedures for the GW25 Rebar Stirrup Bending Machine

Pre-Operation Checks

1. Mechanical Performance:
   • Verify that the machine operates smoothly.
2. Workbench and Machine Table:
   • Ensure they are level.
3. Mandrel Tool Blocks:
   • Prepare the required mandrel tool blocks.

Installation of Components

1. Mandrel and Tools:
   • Install the mandrel, forming shaft, iron shaft, or variable baffle based on the steel bar diameter and machine requirements.
2. Mandrel Diameter:
   • Ensure the mandrel diameter is 2.5 times the steel bar diameter.

Inspection

1. Component Check:
   • Inspect the mandrel, baffle, and turntable for damage or cracks.
2. Protective Cover:
   • Ensure it is securely fastened.
3. Trial Run:
   • Perform a trial run without load to ensure normal operation.

Operation Procedure

1. Steel Bar Placement:
   • Insert the end of the steel bar into the turntable gap.
2. Fixing the Bar:
   • Secure the other end against the machine body and press tightly by hand.
3. Machine Setup:
   • Ensure the machine body is securely fixed and the steel bar is properly blocked before starting.

Safety During Operation

1. Mandrel and Angle Adjustment:
   • Do not replace the mandrel or change the bending angle while the machine is operating.
2. Refueling/Cleaning:
   • Avoid these activities during operation.

Processing Limitations

1. Steel Bar Specifications:
   • Do not exceed the machine’s diameter, root number, or mechanical speed specifications.
2. Mandrel Adjustment:
   • Adjust the maximum limit diameter and replace the mandrel for high-hardness or low-alloy steel bars as per the machine’s nameplate regulations.

Safety Precautions

1. Operating Radius:
   • Do not stand within the operating radius of bending steel bars.
2. Machine Stability:
   • Avoid standing on the unsteady side of the machine.
3. Semi-Finished Products:
   • Stack bent products neatly with hooks facing downwards.
4. Turntable Operation:
   • Reverse the turntable only after it has completely stopped.

Post-Operation

1. Cleanup:
   • Clean the worksite.
2. Machine Maintenance:
   • Perform necessary maintenance.
3. Power Off:
   • Turn off the power and lock the control box.

By adhering to these procedures and safety measures, operators can ensure the GW25 Rebar Stirrup Bending Machine functions efficiently and safely, enhancing overall productivity while minimizing risks.
