Description

Technical Field

[0001] The utility model relates to the technical field of lubrication devices, in particular to an automatic lubrication device for guide rails of hydraulic presses. Background Art

[0002] A hydraulic press is a machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil enters the cylinder / piston through the hydraulic pipeline by the force of the pump. Then there are several sets of seals that cooperate with each other in the cylinder / piston. The seals in different positions are different, but they all play a sealing role to prevent the hydraulic oil from leaking. Finally, the hydraulic oil circulates in the oil tank through a one-way valve to make the cylinder / piston circulate and do work, thereby completing a certain mechanical action as a kind of productivity. When the hydraulic press is running, the guide rail plays an important role in the stability of the hydraulic press, but at the same time, the friction and wear of the guide rail have high requirements.

[0003] When the hydraulic press is running, the guide rails can be continuously and effectively lubricated by installing an automatic lubrication device, thereby reducing friction and wear and improving the stability and reliability of the equipment. This can not only reduce maintenance costs, but also improve production efficiency and the overall operation quality of the equipment.

[0004] At present, the guide rails of hydraulic presses are equipped with automatic lubrication devices. When a fault occurs, it is not convenient to disassemble the oil injection pump body, reduce the workload of personnel loading and unloading, and facilitate maintenance. At the same time, when the oil injection pump body stops running, it is not convenient to prevent the lubricating oil from flowing back. The backflow phenomenon can easily lead to lubricating oil contamination or mixing, affecting the normal operation of the guide rails. Utility Model Content
