The maintenance and upkeep of the head turning edge machine should be combined with the structural characteristics and operational requirements of the equipment, ensuring long-term stable operation through regular inspections, cleaning, and management of key components. Here are the specific methods:
1、 Daily maintenance
1. Equipment cleaning
After each use, it is necessary to thoroughly clean the residual debris and oil stains on the surface of the equipment and the working area to prevent material accumulation from affecting accuracy or causing rust.
Spray rust inhibitor on rotating parts (such as cutting tools and guide rails) to avoid oxidation caused by prolonged exposure.
2. Pre operation inspection
Confirm that the cooling system (if any) has been opened normally to avoid seal failure due to high temperature cracking.
Check if the motor direction is consistent with the direction indicated on the equipment to prevent mechanical failure caused by reverse rotation.
3. Abnormal monitoring
If abnormal vibration or noise occurs during operation, the machine should be stopped immediately for inspection, with a focus on checking whether the transmission components such as bearings and gear sets are worn or loose.
Observe whether there is oil leakage in the sealing area and adjust or replace the sealing components in a timely manner.
2、 Regular maintenance
1. Lubrication management
Add lubricating grease (such as No. 20 mechanical oil) to the transmission parts such as bearings and gears every 500 hours of operation to maintain the oil level within the standard range.
After long-term disuse, it is necessary to replace the lubricant and remove any old grease residue before restarting.
2. Key component inspection
Cutting tools and molds: Regularly measure the wear degree of the cutting edge of the cutting tool. If there are gaps or deformations, they should be repaired or replaced in a timely manner to avoid affecting the edge rotation accuracy.
Fasteners: Check if the bolts, couplings, and other connecting components are loose, and use a torque wrench to tighten them according to the standard (such as connecting rod bolts that require 120N · m).
Bearing and shaft seal: Disassemble and clean the bearing seat, check whether the bearing ball is damaged, whether the sealing ring is aged, and replace it if necessary.
3. Electrical and Control Systems
Clean the dust inside the electrical cabinet, check if the wiring terminals are loose, and ensure that the grounding device is reliable.
Test safety functions such as overload protection and emergency stop button to ensure sensitivity and effectiveness.
3、 Deep maintenance (major overhaul)
1. Disassembly and maintenance
After running for 3000 hours annually or cumulatively, the equipment should be completely disassembled to check key parameters such as spindle straightness and gear mesh clearance, and to repair or replace components that exceed wear limits.
Clean the pipelines, replace the filter element, and test the pressure stability of the hydraulic or pneumatic system (if any).
2. Calibration and Debugging
Adjust the fit gap between the cutting tool and the mold again to ensure that the precision of the edge size meets the process requirements.
Use a dial gauge to measure the dynamic balance of the rotor to avoid increased vibration caused by imbalance.
4、 Security and Record Management
1. Operating standards
Untrained personnel are prohibited from operating the equipment, and direct contact with rotating parts is strictly prohibited during operation.
Metal debris or hard foreign objects must not be mixed into the material to prevent tool jamming or damage.
2. Maintain records
Establish maintenance records, detailing the content of each maintenance, replacement of parts, and measures for handling abnormalities, for easy traceability and analysis.
Through the above maintenance measures, the failure rate of the head turning machine can be significantly reduced, the equipment life can be extended, and the processing quality can be guaranteed.
