Maintenance and upkeep of the press brake

Before performing machine maintenance or cleaning, the upper punch should be aligned with the lower dies and the machine should be lowered and turned off until the work is completed. If startup or other operations are required, the mode should be selected as manual and safety should be ensured. The maintenance content is as follows:

1. Hydraulic oil circuit

1) Check the oil level in the fuel tank every week, and also check it after hydraulic system maintenance. If the oil level is below the oil window, add hydraulic oil;

2) The hydraulic oil used in this machine is ISO HM46 or MOBIL DTE25;

3) The new machine should have its oil changed after 2000 hours of operation, and every 4000-6000 hours of operation thereafter. After each oil change, the oil tank should be cleaned;

4) The system oil temperature should be between 35 ℃ and 60 ℃, and should not exceed 70 ℃. If it is too high, it may cause deterioration and damage to the oil quality and accessories.

2. Filter

1) The filter should be replaced or thoroughly cleaned every time the oil is changed;

2) If the machine tool has related alarms or other filter abnormalities such as poor oil quality, it should be replaced;

3) The air filter on the fuel tank should be inspected and cleaned every 3 months, preferably replaced every year.

3. Hydraulic components

1) Clean hydraulic components (substrates, valves, motors, pumps, oil pipes, etc.) monthly to prevent dirt from entering the system and avoid using cleaning agents;

2) After using the new machine for one month, check if there is any deformation at the bends of each oil pipe. If there is any abnormality, it should be replaced. After using it for two months, tighten all the connections of the accessories. When doing this work, the machine should be turned off and the system should be free of pressure.
