Troubleshooting & Maintenance for Your Metal Roofing Sheet Roll Forming Machine

The Metal Roofing Sheet Roll Forming Machine is a critical piece of equipment in the construction and manufacturing industries. These machines shape metal sheets into desirable roofing profiles, ensuring the quality and durability of your building materials. However, as with any machinery, challenges can arise that may affect their performance. Here, we provide a comprehensive guide to troubleshooting common issues and ensuring optimal maintenance practices for your Roll Forming Machines.

Troubleshooting Common Issues

Control Box Power Issues

If your control box is not receiving power, there are several potential causes to investigate:

1. Check the external power supply to ensure it’s working properly.
2. Examine the control box for any loose connections or frayed ends.
3. Assess the electrical components for any signs of damage, replacing accessories as needed.
4. Verify if the emergency stop is engaged.

Oil Pump Start-up Challenges

If your oil pump isn’t starting, you should:

1. Confirm the input power.
2. Test the start button.
3. Inspect the oil pump contactor during startup.
4. Examine the oil pump motor.

Movement Restrictions in the Host Machine

If the host machine isn’t moving forward or backward:

1. Check the host forward button.
2. Assess whether the inverter is showing an alarm.
3. Verify if the emergency stop button is pressed.
4. Test the power switch.
5. Inspect for a steel band jam.
6. Check if the electrical components are functioning properly. Please contact the manufacturer for assistance, as non-professionals should not alter the electrical components.

Accountant Length Deviations

If the accountant length is showing large deviations:

1. Confirm if the mechanical part of the encoder is in good condition, and whether the counting wheel is in contact with the steel.
2. Check if the connecting shaft inside the encoder is damaged or slipping.
3. The encoder circuit should be separated from the power line to avoid interference.
4. The deceleration length should be set around 100-150mm to reduce inertia and improve accuracy.

Regular Maintenance Practices

Daily maintenance is vital to ensure your metal roofing sheet roll forming machine runs smoothly:

1. Adjust the screws and add oil once per shift.
2. The bearings should be filled with calcium-based lubricant every six months.
3. Check the drive chain and add calcium base oil monthly.
4. Oil the tool and die parts before operating the equipment.
5. Replace the hydraulic oil every 18 months or as required.
6. Listen for abnormal noise from the oil pump and main motor before starting the machine.
7. Keep the control box clean and dust-free.

By adhering to these troubleshooting and maintenance guidelines, you’ll ensure the longevity and efficiency of your Metal Roofing Sheet Roll Forming Machine, resulting in higher quality products and increased productivity.
