Maintenance And Care Of Bending Machines

Before performing machine maintenance or cleaning, the upper die should be aligned with the lower die and then lowered and shut down until the work is completed. If you need to start the machine or perform other operations, the mode should be selected in manual mode and ensure safety. The maintenance contents are as follows:
1. Hydraulic oil circuit
1) Check the oil level in 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, hydraulic oil should be added;
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 worked for 2000 hours, and the oil should be changed every 4000-6000 hours thereafter. The oil tank should be cleaned every time the oil is changed;
4) The system oil temperature should be between 35℃ and 60℃, and should not exceed 70℃. If it is too high, it will cause deterioration and damage of the oil quality and accessories.
2. Filter
1) Every time the oil is changed, the filter should be replaced or thoroughly cleaned;
2) If the machine tool has related alarms or other filters such as unclean oil quality, they should be replaced;
3) The air filter on the oil tank should be checked and cleaned every 3 months, and it is best to replace it once a year.
3. Hydraulic components
1) Clean the hydraulic components (base plate, valve, motor, pump, oil pipe, etc.) every month to prevent dirt from entering the system. Do not use detergents;
2) After a new machine has been used for one month, check whether the bends of the oil pipes are deformed. If there are any abnormalities, they should be replaced. After two months of use, the connections of all accessories should be tightened. When doing this work, the machine should be turned off and the system should be pressure-free.
