Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control hydraulic presses, and in particular relates to a four-column numerical control hydraulic press with stable stamping. Background Art

[0002] A hydraulic press (a type of 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.
