Maintenance And Care Guide For Hairpin Flat Wire Motor Production Line

With the rapid development of the new energy vehicle industry, hairpin flat wire motors have become the core components of the drive system due to their high efficiency and high power density. The stable operation of its production line is directly related to product quality and production efficiency. Therefore, scientific maintenance and care are particularly important. This article will introduce you to the maintenance and care guide for hairpin flat wire motor production lines in detail to help enterprises extend equipment life, reduce failure rates and improve production efficiency.

1. Core components of production line equipment

Hairpin flat wire motor production lines usually include coil forming machines, wire insertion machines, welding equipment, testing equipment, and automated transmission systems. These equipment are prone to wear, looseness or electrical failure under high-intensity, continuous operation environments. Therefore, maintenance work needs to be carried out around mechanical parts, electrical systems, and automated control systems.

2. Daily maintenance points

Cleaning and lubrication

In the production environment, dust and metal chips may accumulate on the surface of the equipment or in key components. It is recommended to clean the surface of the equipment daily, especially the guide rails, molds, and conveyor belts. At the same time, check the lubrication system regularly to ensure that moving parts such as bearings and sliders are well lubricated to avoid excessive wear caused by friction. Use high-quality lubricants suitable for the equipment and follow the manufacturer's recommended replacement cycle.

Tightening and calibration

High-frequency vibrations may cause bolts and connectors to loosen. Maintenance personnel should check the key connection points of the equipment every week and tighten them according to the standard torque using a torque wrench. In addition, the molds of the coil forming machine and the wire insertion machine need to be calibrated regularly to ensure product accuracy. During the calibration process, professional tools are required to measure the mold gap to ensure that it meets the process requirements.

Electrical system inspection

The electrical system is the "brain" of the production line operation. During maintenance, it is necessary to check whether the cables are aging, whether the connectors are loose, and use a multimeter to detect the stability of voltage and current. The cooling fans of the servo motor and inverter need to be cleaned regularly to avoid performance degradation due to overheating. It is recommended to conduct a comprehensive electrical system inspection once a month and record abnormal data to trace the root cause of the problem.

3. Preventive maintenance strategy

Develop a maintenance plan

Develop detailed monthly, quarterly and annual maintenance plans based on the frequency of equipment use and production tasks. For example, quarterly maintenance may include replacing severely worn molds and conveyor belts; annual maintenance should be carried out by fully disassembling the equipment and repairing or replacing aging parts.

Data monitoring and predictive maintenance

Modern production lines are often equipped with sensors and intelligent monitoring systems that can collect equipment operation data in real time, such as temperature, vibration, and current. By analyzing this data, the maintenance team can detect potential faults in advance. For example, abnormal vibration may indicate bearing wear, and timely replacement can avoid downtime losses.

Personnel training

Equipment maintenance cannot be separated from professionals. Enterprises should regularly organize operators and maintenance personnel to participate in training to learn equipment principles, common troubleshooting methods, and the latest maintenance techniques. Skilled operation and maintenance can significantly reduce failures caused by human errors.

4. Common problems and countermeasures

Inaccurate coil forming: Check the wear of the mold and replace the mold if necessary; calibrate the pressure and speed parameters of the molding machine.

Unstable welding quality: Clean the welding head to ensure that there are no impurities in the welding area; check the current output stability of the welding equipment.

Conveyor belt deviation: Adjust the conveyor belt tension and centering device, and check whether the roller is worn.

5. Conclusion

The maintenance and maintenance of the hairpin flat wire motor production line is a systematic work, covering multiple aspects such as daily cleaning, regular inspections, and preventive maintenance. Through scientific management and standardized operation, enterprises can not only extend the service life of equipment, but also effectively improve production efficiency and product quality. I hope this guide can provide a practical reference for your production line maintenance work and make production smoother and more efficient!
