Before the machine is maintained or the machine is wiped, the upper die should be put down and put down to the end of the machine until the work is finished. If you need to start the machine or other operation, the mode should be selected manually and the safety should be ensured. CNC bending machine maintenance is as follows:
1。 Hydraulic oil road
A. check the oil level of the fuel tank every week. After the maintenance of the hydraulic system, it should also check that the oil level should be filled with hydraulic oil below the oil window.
b.本机所用液压油为ISO HM46或MOBIL DTE25；
B. the hydraulic oil used for this machine is ISO HM46 or MOBIL DTE25.
C。 new engine should be changed after 2000 hours of work。 After every 4000~6000 hours of work, oil should be changed。
The oil temperature of the D。 system should be between 35 and 60 degrees centigrade, and should not exceed 70 degrees。
A。 every time the oil change, the filter should be replaced or thoroughly cleaned。
B. filter has abnormal alarm or unclean oil and other filters. It should be replaced.
The air filter on the C. tank is cleaned every 3 months, preferably in 1 years.
3. Hydraulic components
A。 clean the hydraulic components (base plate, valves, motors, pumps, tubing, etc。) every month to prevent dirt from entering the system, and no cleaning agent can be used。
B. new machine is used for one month to check the deformation of the tubing bend, if abnormal should be replaced. After two months, the connection of all parts should be fastened and the work should be shut down. The pressure free hydraulic bending machine of the system includes the support, worktable and clamping plate. The worktable is placed on the support and the worktable is made from the worktable. The base is composed of a hinge and a clamping plate. The base is composed of a seat shell, a coil and a cover plate. The coil is placed in a sag of the seat shell, and the top of the sag is covered with a cover plate.
