hydraulic press brake care and maintenance

Hydraulic press brake working principle

The hydraulic press brake includes a support, a workbench and a clamping plate. The workbench is placed on the support. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate through a hinge. The base is composed of a housing, a coil and a cover. It is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate.

When in use, the wire is energized to the coil, and the gravitational force is generated on the pressing plate after being energized, thereby realizing the clamping of the thin plate between the pressing plate and the base. Due to the use of electromagnetic force clamping, the pressing plate can be made into a variety of workpiece requirements, and workpieces with side walls can be processed. The hydraulic press brake can meet the needs of various workpieces by changing the mold of the hydraulic press brake.

Hydraulic press brake care and maintenance

Before machine maintenance or cleaning, the upper mold should be aligned with the lower mold and then shut down until the work is completed. If you need to start or perform other operations, select the manual mode and ensure safety. The maintenance content is as follows:

1. Hydraulic oil circuit

1) Check the oil level of the oil tank every week. If the hydraulic system is repaired, it should also be checked. If the oil level is lower than the oil window, add hydraulic oil;
2) The hydraulic oil used in this machine is ISO HM46 or MOBIL DTE25;
3) The oil should be changed after the new machine has been working for 2000 hours, and the oil should be changed after every 4000 to 6000 hours of work thereafter, and the oil tank should be cleaned every time the oil is changed;
4) The oil temperature of the system should be between 35℃～60℃ and not exceed 70℃. If it is too high, it will cause deterioration and damage of the oil quality and accessories.

2. Filter

1) The filter should be replaced or thoroughly cleaned every time the oil is changed;
2) The machine tool has related alarms or other filter abnormalities such as unclean oil, and should be replaced;
3) The air filter on the fuel tank should be inspected and cleaned every 3 months, preferably 1 year.

3. Hydraulic components

1) Clean hydraulic components (base plates, valves, motors, pumps, oil pipes, etc.) monthly to prevent dirt from entering the system, and cleaning agents cannot be used;
2) After using the new machine for one month, check whether there is any deformation in the bends of the oil pipes. If there is any abnormality, they should be replaced. After two months of use, all fittings should be tightened. The system should be shut down during this work. pressure.
