Getting the most out of your steel bar straightening machine depends on setting the right cutting and return times. These settings are key for smooth and precise operation, especially when dealing with thicker or harder steel bars. Here’s a clear guide on how to adjust these settings to improve your machine’s performance.
What are Cutting and Return Times?
Cutting Time
- Default Setting: Most machines come with a cutting time of 1.4 seconds (140 milliseconds). This is a balance between speed and accuracy.
- Why Adjust It?: Depending on the type of steel, you might need to extend the cutting time to ensure better accuracy and smoother operations, especially if you’re doing continuous cuts.
Return Time
- Importance: Return time helps the machine reset without the steel bar getting stuck or hitting the blade. If you notice issues during cutting, increasing the return time often fixes the problem.
- Manufacturer Differences: While settings may vary by manufacturer, adjusting the return time can help ensure smoother and safer operation.
How to Adjust Cutting and Return Times
To adjust these settings on a computer-controlled steel bar straightening machine, follow these steps:
1. Power On and Reset
- Turn on the machine, and the LCD display should reset to zero.
- Enter the settings mode by pressing keys [1], [3], and [5] at the same time. The machine’s default outlet times are already set for optimal performance.
2. Adjust Cutting Time
- When the batch display shows “11” and the length window reads “t1,” the quantity window will show “200” (meaning the current cutting time is set to 0.200 seconds).
- Adjust the time using the number keys, and press Enter to confirm the new cutting time.
3. Set Return Time
- When the batch display changes to “22” and the length window shows “t2,” the quantity window will show “180” (indicating the return time is 0.180 seconds).
- Adjust the return time with the number keys, and press [OK] to save the changes and exit the settings mode.
Manufacturer Differences to Keep in Mind
- Cutting times generally range from 0.100 to 0.260 seconds.
- Mechanical cutting time is often fixed at 0.060 seconds.
- Some machines, like single-tube hydraulic presses, allow you to adjust only the cutting time and not the return time.
Precautions for Adjusting Settings
- Avoid Changing Factory Settings: The factory-set end times and export times are carefully calibrated. Altering these can cause problems.
- Potential Issues: Incorrect settings may result in low pressure, preventing proper cutting. Too much pressure can lead to oil leaks, wear on the hydraulic system, motor overload, and overheating.
Conclusion
Setting the correct cutting and return times is crucial for getting the best performance from your steel bar straightening machine. By regularly checking and adjusting these settings according to the manufacturer’s guidelines, you can ensure your machine runs smoothly and efficiently. Proper configuration not only improves the quality of your work but also helps prevent unnecessary wear and tear, saving you time and money in the long run.
