How to effectively maintain the Press Brake machine



Correct and safe specific maintenance methods and daily inspections of Press brake machines.

How to effectively maintain the Press Brake machine

Before maintenance of the press brake or wiping the machine, the upper die must be aligned with the lower die, and then put down the machine to stop working until the work is completed. If you need to start up or other operations, you must choose manual mode to ensure safety. The maintenance method is as follows:

1.Hydraulic oil circuit


a. Check the oil level in the oil tank every week, also after maintenance of the hydraulic system, if the oil level is lower than the oil window, the hydraulic oil needs to be topped up.


b. The oil should be changed for the new machine after 2000 hours of operation, after that, the oil should be changed every 4000-6000 hours of operation, and the oil storage tank should be cleaned every time the oil is changed.

c. The oil temperature of the system should be between 35°C and 60°C, and should not exceed 70°C. If the temperature is too high, the oil quality will decrease and accessories will be damaged.

2. Filter

a. Filters should be replaced or thoroughly cleaned at every oil change.

b. If there are related alarms or the oil quality is not clean, other filters of the machine tool are abnormal, and the filters must be replaced.

c. The air filter on the fuel tank should be checked and cleaned every 3 months, preferably every year.

3. Hydraulic components

a. Clean hydraulic components (substrate, valves, motors, pumps, oil pipes, etc.) monthly to prevent contamination from entering the system and should not use cleaning agents.

b. After the new machine is used for one month, check whether the elbow of the oil pipe is deformed. If there is any abnormality, it should be replaced. After two months of use, the connections of all accessories should be tightened, the work should be stopped, and the system should be free of pressure.

Daily maintenance of automatic Press Brake machine:

1. Check whether the starting is normal, whether the operating system is normal, whether the shaft is normal, whether the engine is running normally, whether there is abnormal noise in the machine operation, whether the upper and lower gears are good; whether the upper knife is flexible, whether the foot switch is good, whether the starting is sensitive, and the pressure gauge Whether it is normal, whether the hydraulic cylinder pressure is normal, whether the hydraulic oil pipe and oil cylinder leak oil.

2. Lubricate the ball screw and rolling guide every day after cleaning, make sure the mold is clean, check whether the fiber optic rod is dirty, and clean around it, clean the body, and check the oil level in the fuel tank every week. Check whether there is water in the air pump and whether the air circuit is blocked, regularly clean the oil outlet filter, clean the hydraulic parts every month to prevent dirt from entering the system, do not use cleaning agents, and regularly check the oil tank of the air-liquid pump.
