Steel Bar Straighten Machine, For optimal performance and safety, it is essential to follow the correct operating procedures when using a steel bar straightening machine. Below are step-by-step instructions to help ensure efficient operation and prevent accidents during use.
1. Adjusting for Steel Bar Diameter:
- Straightening Wheel and Traction Groove:
Select the appropriate straightening wheel based on the diameter of the steel bar. Ensure the traction pulley groove matches the bar diameter. The straightening wheel should apply adequate pressure to the bar, while the groove width should perfectly align with its dimensions. - Set Transmission Speed:
Adjust the transmission speed to match the steel bar diameter for efficient straightening without damaging the material.
2. Straightening Wheel Adjustment:
- Configuration:
The straightening cylinder typically includes 6-8 wheels. The first and eighth wheels should be aligned with the centerline of the machine, while the middle wheels can be slightly offset. - Trial and Adjustment:
Begin with a 3mm offset from the centerline. If the steel bar continues to bend, incrementally increase the offset until it is completely straightened.
3. Length Verification:
- Initial Check:
After processing 3-4 steel bars, pause the machine to verify the cut lengths. - Adjustments:
If there are discrepancies in the bar lengths, adjust the limit switch or length plate until the desired length is achieved.
4. Safety Measures for Steel Bar Handling:
- Guide Pipe Installation:
Use a steel bar approximately 1 meter long at the front of the guide pipe. Ensure that the straightened bars pass through the steel pipe, followed by the guide tube and straightening tube. This prevents the bars from popping out unexpectedly, reducing the risk of injury.
5. Precautions Before Fixing Straightening Wheels:
- Protective Cover:
Never insert steel bars if the straightening wheels are not secured, and the protective cover is not in place. This precaution prevents straightening blocks from being ejected, which could cause serious injuries.
6. Operational Safety:
- Avoid Object Stacking:
Do not place any objects on the machine to prevent mechanical vibrations, which can lead to accidents. - Maintain Safe Distance:
Keep your hands away from the pressing rollers during steel bar loading. Avoid making roller adjustments while the machine is in operation, and do not wear gloves, as they can get caught in the rollers.
7. Handling Steel Bars:
- Maintain a Safety Distance:
Ensure that all personnel stand clear of the machine while it is processing steel bars to avoid being struck by materials. - Processing Specifications:
For steel bars shorter than 2 meters or diameters greater than 9mm, operate the machine at a lower speed. This prevents the bar from misalignment and ensures proper straightening.
Final Note:
By adhering to these detailed operating instructions, you will maintain both the efficiency and safety of the steel bar straightening machine. Proper handling will not only ensure high-quality results but also provide a safe working environment for all personnel involved.
