As a common punching machine, hydraulic press plays an important role in production. In order to ensure the normal operation of the hydraulic press and extend its service life, maintenance work is particularly important. Below, I will share the maintenance points of the hydraulic press, including daily maintenance, regular maintenance and special maintenance.
1. Key points of daily maintenance
1. Keep the machine clean: the machine should be cleaned before starting and stopping every day, including cleaning oil dirt, cleaning slide, cleaning air intake, etc. When cleaning, pay attention to the use of professional cleaning agents to avoid any surface damage.
2. Check the lubrication system: check the lubrication system of the oil press regularly to ensure that the oil is sufficient and normal flow. At the same time, it is also necessary to check the oil seal of the lubrication system, and if oil leakage is found, it needs to be replaced or repaired in time.
3. Observe the lubrication condition: regularly observe the lubrication condition of the moving parts of the machine tool. If you find insufficient lubrication or dry problems, you should add lubricating oil or grease in time.
4. Check the electrical system: regularly check the electrical system of the hydraulic press to ensure that the motor and wiring are normal. In particular, the contact part of the cable line and contactor should be checked for loosening or corrosion.
5. Pay attention to protection: When using the hydraulic press, pay attention to prevent dust and foreign matter from entering the machine tool to prevent the normal operation of the machine tool. At the same time, pay attention to protect the relevant safety protection devices to ensure the personal safety of the staff.
Two, regular maintenance points
1. Replace the lubricating oil: replace the lubricating oil of the oil press regularly, and replace the oil in time according to the use situation and requirements to maintain the normal operation of the lubrication system. When replacing lubricating oil, pay attention to the operating specifications in the discharge, cleaning and filling process.
2. Cleaning slider: Regularly clean the slider of the hydraulic press to remove impurities such as dust and debris. After cleaning, dry the slider to avoid moisture residue, resulting in component corrosion.
3. Check the fastening bolts: Check the fastening bolts in each part of the punch regularly. If loose bolts are found, tighten them in time. At the same time, pay attention to whether the surface of the fastening bolt is corroded or damaged, and replace it in time if necessary.
4. Maintenance of the oil cylinder: Regularly maintain the oil cylinder of the hydraulic press, including checking the oil seal, cleaning the impurities in the cylinder, discharging the waste oil, etc. If the oil seal is found damaged or leaking, it should be replaced and repaired in time.
5. Consider winter maintenance: When using oil press in winter, pay special attention to maintenance work. In low temperature environments, it is necessary to heat hydraulic oil, etc., to ensure the normal operation of the machine tool.
Three, special maintenance points
1. Regular lubrication of the piston rod: The piston rod of the hydraulic press is a key moving part and needs to be regularly lubricated. The grease should choose the special product suitable for the piston rod, and pay attention to the uniformity of the coating to ensure the normal operation of the piston rod.
2. Check the return system: The return system of the hydraulic press is a key safety component. Regularly check the normal operation of the return system, the work of the shock absorber, etc., and make necessary adjustments and repairs.
3. Regular maintenance of the control system: the control system of the hydraulic press is an important part of ensuring the normal operation of the machine tool. Check, clean and calibrate the control system regularly to avoid electrical failure.
To sum up, the maintenance of the hydraulic press is an important measure to ensure its normal operation and extend its service life. Daily maintenance, regular maintenance and special maintenance are essential, only scientific and reasonable maintenance, in order to ensure the efficient and stable operation of the hydraulic press, improve production efficiency, reduce the failure rate, extend its service life. Therefore, each punching machine operator should carefully grasp the maintenance points of the hydraulic punching machine, and operate in accordance with the operating specifications to ensure the normal operation of the machine.
