Hydraulic Press Maintenance System

Maintenance and care
1. The recommended working oil is No. 32 or No. 46 anti-wear hydraulic oil, and the oil temperature is within the range of 15 to 60 degrees Celsius.
2. The oil is allowed to be added to the oil tank only after strict filtration.
3. The working oil should be replaced once a year, and the first replacement time should not exceed three months;
4. The slider should be regularly filled with lubricating oil, the exposed surface of the column should be kept clean at all times, and the oil should be sprayed before each work.
5. The maximum allowable eccentricity of the concentrated load is 40mm under the nominal pressure of 500T. Excessive eccentricity can easily cause the column to be strained or other adverse phenomena.
6. Calibrate and check the pressure gauge every six months;
7. If the machine is out of use for a long time, the surface of each part should be cleaned and coated with anti-rust oil.
Safety operation matters
1. Those who do not understand the machine structure performance or operation procedures should not start the machine without authorization;
2. The mold should not be repaired or adjusted during the operation of the machine;
3. When the machine is found to have serious oil leakage or other abnormalities (such as unreliable movement, loud noise, vibration, etc.), it should be stopped to analyze the reasons and try to eliminate them. It is not allowed to be put into production with problems:
4. It is not allowed to be overloaded or used beyond the maximum eccentricity:
5. It is strictly forbidden to exceed the maximum stroke of the slider, and the minimum mold closing height shall not be less than 600mm.
6. The grounding of electrical equipment must be firm and reliable:
7. At the end of each day's work: put the slider to the lowest position.
Secondary maintenance
1. The machine tool is operated for 5000 hours for secondary maintenance. It is mainly repaired by maintenance workers, and operators participate. In addition to performing the first-level maintenance content, the following work should be done, and the wearing parts should be mapped. Spare parts are proposed.
2. First, cut off the power supply for maintenance work. (See the table below)
Serial number Maintenance part Maintenance content and requirements
I. Beam column guide rail 1. Check and adjust the plane of the hanging beam, column guide rail, guide sleeve, slider, and pressure plate to achieve smooth movement and meet the process requirements.
2. Repair or replace defective parts.
2. Hydraulic lubrication 1. Disassemble and clean the solenoid valve, grind the valve and valve core.
2. Clean and check the oil pump cylinder plunger, polish the burrs, and replace the oil seal
3. Check the pressure gauge
4. Repair or replace severely worn parts
5. Check that each cylinder and plunger are running smoothly without creeping. The support valve can stop the movable beam accurately at any position, and the pressure drop meets the process requirements.
3. Electrical appliances 1. Clean the motor, check the bearings, and update the grease
2. Repair or replace damaged components.
3. The electrical appliances meet the equipment integrity standards.
4. Accuracy 1. Calibrate the machine tool level, check and adjust the repair accuracy.
2. The accuracy meets the equipment integrity standards.
The maintenance and maintenance of the hydraulic press still requires dedicated, professional, and full-time maintenance, so that it can be used for a longer time!
