Bending machine is a kind of machine that can bend thin plates. Bending machine is divided into manual bending machine, hydraulic bending machine and NC bending machine.
So how to maintain the bending machine at ordinary times? It is divided into three parts: hydraulic oil circuit, filter and hydraulic components.
Before the maintenance or cleaning of the machine tool, the upper mold should be aligned with the lower mold and then put down and shut down until the work is completed. If it is necessary to start the machine or other operations, the mode should be selected in manual and ensure safety. The specific maintenance contents are as follows:
1. Hydraulic oil circuit
1) Check the oil level of the oil tank every week. 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 of the new machine shall be changed after 2000 hours of operation, and the oil shall be changed after 4000 ~ 6000 hours of operation. Each time the oil is changed, the oil tank shall be cleaned;
4) The oil temperature of the system shall be between 35 ℃ and 60 ℃ and shall not exceed 70 ℃. If it is too high, the oil quality and accessories will be deteriorated and damaged.
1) During each oil change, the filter shall be replaced or thoroughly cleaned;
2) The machine tool has relevant alarms or other abnormal filters such as unclean oil quality, which should be replaced;
3) The air filter on the oil tank shall be inspected and cleaned every 3 months, and it is best to replace it once a year.
3. Hydraulic components
1) Clean hydraulic components (base plate, valve, motor, pump, oil pipe, etc.) every month to prevent dirt from entering the system, and do not use detergent;
2) After the new machine is used for one month, check whether there is deformation at the bend of each oil pipe. If there is any abnormality, replace it. After two months of use, fasten the connection of all accessories. When doing this work, shut down the machine and there is no pressure in the system.
