CNC press brakes are widely used in metalworking for performing various complex bending operations with high accuracy and stability. This article provides a detailed step-by-step guide on setting parameters on a CNC press brake, helping you maximize the functionality of your equipment and enhance processing efficiency.
Steps for Setting Parameters on a CNC Press Brake
1. Power-On Self-Test
Before starting the CNC press brake, conduct a power-on self-test. During this process, the system checks all components to ensure the equipment is in working order. If any anomalies are detected, address them immediately to prevent operational issues.
2. Enter Parameter Setting Interface
Once the self-test is complete, access the parameter setting interface of the CNC press brake. Depending on the model, this interface can be navigated using a touchscreen or physical buttons.
3. Select Parameter Type
In the parameter setting interface, the first step is to choose the type of parameter you wish to set. Common parameter types include:
- Bending Angle
- Bending Speed
- Pressure
- Upper Mold Height
- Lower Mold Height
- Back Gauge Position
4. Set Parameter Values
Locate the specific parameter you need to set and input the corresponding value. Some parameters may require units like degrees, millimeters per second, etc. Ensure the accuracy and consistency of the data you enter to avoid operational errors.
5. Save Parameters
After setting the parameter values, save them into the system. This is typically done by clicking a save or confirm button. Some CNC press brakes offer a parameter backup feature, allowing you to save the current parameters as a file for future reference and restoration.
6. Verify Parameter Settings
After saving, verify the parameter settings to ensure they meet the actual processing requirements. You can do this by previewing the bending process or simulating the bending operation to check the correctness of the settings.
7. Adjust Parameters
If issues are found during the verification process, return to the parameter setting interface to make adjustments. Follow the equipment’s manual and operational guidelines to avoid damaging the machine during adjustments.
8. Complete Parameter Setting
Once the parameter settings are confirmed to be accurate, exit the parameter setting interface and begin the bending operation. Monitor the machine’s performance closely during the actual operation, ready to address any unexpected issues promptly.
How to Adjust Bending Angles When Ends Differ
During the bending process, you might notice that the angles at both ends of the workpiece are not the same. Here’s how to adjust the press brake to correct this issue:
1. Check for Deviations
Ensure the free state deviation on both sides of the press brake is within the normal range of 0.20-0.30 mm. If the deviation exceeds this range, use a single-sided eccentric sleeve to adjust until both sides are within acceptable limits.
2. Use Hexagonal Tube for Adjustment
Based on the angle error at the ends of the bent plate, use the hexagonal tube on the press brake for single-side adjustment. Disconnect one end of the hexagonal tube, and use the Y-axis handwheel (one full turn equals 0.10 mm) to adjust according to the size of the angle error. Reconnect the hexagonal tube after adjustment.
Important Notes:
- Be aware that extending the material upwards during bending can cause collisions with the mold or slider, resulting in inaccurate bends.
- It is normal for the bending angles to differ slightly on the left and right sides. Use an angle gauge to measure which side has a larger deviation and adjust accordingly on the machine.
- For manual press brakes, rely on experience for adjustments, as direct machine adjustments may not be feasible.
