Electro-hydraulic CNC bending machine adopts crank connecting rod mechanism,
the action depends on the numerical control system to control the opening size of proportional servo valve to adjust the amount of oil in the cylinder,
so as to control the synchronization of the motion speed of the supporting material and the bending speed of the sheet metal.
Maintenance and maintenance of electro-hydraulic CNC bending machine:
1. Hydraulic oil circuit
A. Lubrication each point daily according to lubrication requirements.
B. Clean the ball screw and rolling guide rail every day and lubricate them.
C. Wipe the residue from the mold every day before work.
D. Clean the filter screen of oil outlet filter regularly.
E. Check the gas and liquid pump tank regularly, replace it after the first use for one month, and then replace the oil according to the specific situation every year, the oil temperature is not less than 10C.
F. Check the oil level of the tank every week, including after the maintenance of the hydraulic system. If the oil level is lower than the oil window, add hydraulic oil;
G. Add yB-N46 hydraulic oil into the tank, which must be filtered by an oil filter less than 10 mesh for more than five times. Refueling can only be done after the tank is cleaned, and the depth is within the range of the tank scale;
2. Filter
A. Every time the oil is changed, the filter should be replaced or cleaned thoroughly;
B. If the machine has related alarm or oil is not clean and other filter abnormalities, it should be replaced;
C. The filter on the fuel tank should be checked and cleaned every 3 months, and it is recommended to replace it every 1 year.
