Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic tooling lubrication, in particular to a hydraulic lubrication maintenance structure. Background Art

[0002] The hydraulic tooling is a tooling structure driven by a hydraulic transmission system. Hydraulic cylinders and hydraulic rods are arranged on the tooling plates to cooperate with the tooling plates to clamp and limit materials. After long-term use, the mechanical active structure on the tooling is prone to rust and needs to be lubricated with lubricating fluid. This lubrication and maintenance structure is used to add lubricating fluid to and maintain the mechanical active structure of the tooling.

For ordinary lubrication operations, it is necessary to add lubricating fluid to the active structures. However, due to the different shapes of the active structures of different tooling, it is difficult to fully lubricate the pores and socket gaps of each active structure of the tooling plate when adding lubricating fluid, resulting in unsatisfactory lubrication effect.
