Bending machines are indispensable tools in metal fabrication, providing the capability to bend metal sheets into precise shapes. Properly adjusting these machines and managing their control systems is essential for accurate and efficient operations. This guide will walk you through the steps to adjust the size on a bending machine and manage its control system effectively.
Adjusting the Size on a Bending Machine
1. Setting the Collision Block II Position
Adjusting the position of Collision Block II is crucial for setting the upper dead point, where the slider will stop on its upward return. Here’s how you do it:
Steps:
1. Identify Collision Block II: Locate the block within the machine that will control the upper dead point.
2. Adjust Position: Move the block to the desired position that corresponds to the upper dead point needed for your specific bending task.
3. Test the Adjustment: Run a test to ensure the slider stops at the correct upper dead point.
2. Adjusting Based on Sheet Thickness, Bending Angle, and Slider's Bottom Dead Point
The adjustment process should take into account the sheet thickness, desired bending angle, and the slider's bottom dead point.
Steps:
1. Determine Requirements: Identify the sheet thickness and the desired bending angle for your project.
2. Set Bottom Dead Point: Adjust the machine settings to ensure the slider reaches the correct bottom dead point.
3. Fine-Tune Position: Move Collision Block II downward until the slider cannot move further, indicating the bottom limit.
How to Adjust Bending Machine Dimensions
1. Fixed Step Mold Adjustment
When using a fixed step mold, the double-bend corner dimension remains constant.
Steps:
1. Select Fixed Step Mold: Choose the appropriate mold for the sheet metal and bending requirements.
2. Align and Secure Mold: Ensure the mold is properly aligned and securely fastened in the machine.
Managing the Control System of a Bending Machine

1. Powering Up the System
Steps:
1. Connect Power Supply: Ensure the machine is connected to the power source.
2. Turn on Key Switch: Locate and turn on the key switch on the control panel.
3. Start Oil Pump: Press the oil pump start button to activate the hydraulic system.
2. Adjusting the Stroke
Stroke adjustment is critical to ensure that the slider moves correctly within the machine’s operating limits.
Steps:
1. Identify Stroke Requirements: Determine the necessary stroke length for your bending task.
2. Adjust Stroke Settings: Use the control panel to set the stroke length. Make sure there is a gap equal to the sheet thickness when the upper die is at its lowest point to avoid damage.
3. Test the Stroke: Run a test bend to ensure the stroke is set correctly and adjust as needed.
3. Operating the Foot Pedal
The foot pedal controls the bending operation and allows for precise control during the process.
Steps:
1. Press Foot Pedal to Start Bending: Initiate the bending process by pressing down on the foot pedal.
2. Release to Stop: Release the pedal to stop the bending process at any time.
3. Continue Bending: Press the pedal again to continue bending.
Troubleshooting Common Issues
1. Inaccurate Bending Angles or Unstable Operations
Potential Causes:
- Program Errors: Verify the CNC program for errors and ensure parameters are correctly set.
- Back Gauge Position: Check the position of the back gauge for accuracy.
- Mechanical Wear: Inspect for mechanical wear or looseness and tighten or replace components as necessary.
2. High-Speed Descent Problems
Potential Causes:
- Hydraulic System Faults: Inspect hydraulic valves and pumps for defects.
- Electrical Component Failures: Ensure all electrical components are functioning properly.
- Oil Contamination: Clean the hydraulic system and replace the oil if contamination is found.
3. Back Gauge Malfunctions
Potential Causes:
- Motor Issues: Inspect and repair or replace damaged back gauge motors.
- Encoder/Sensor Issues: Check encoders and position sensors for proper function.
4. CNC System Faults
Potential Causes:
- Software/Hardware Failures: Verify the CNC system software and check for hardware issues.
- Communication Errors: Ensure proper communication between the CNC and servo systems.
Expert Repair Recommendations
If you encounter issues that cannot be resolved through basic troubleshooting, seek professional assistance:
- Contact the Manufacturer: Reach out to the manufacturer or an authorized service provider for expert support.
- Regular Maintenance: Conduct regular inspections and maintenance to prevent faults and ensure optimal machine performance.
Conclusion
Adjusting the size and managing the control system of a bending machine is essential for accurate and efficient metal bending operations. By following the detailed steps and troubleshooting methods outlined in this guide, you can enhance the performance and reliability of your bending machine. Regular maintenance and timely professional assistance are key to keeping your machine in optimal working condition.
