Description

Technical Field

[0001] The utility model belongs to the technical field of noise reduction devices, and in particular relates to a noise reduction device for an oil press. Background Art

[0002] A hydraulic press (a type of hydraulic press) is a machine that uses special hydraulic oil as a working medium and a hydraulic pump as a 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 machine. However, during the operation of the hydraulic press, it will generate a lot of noise, which is inconvenient for the staff to communicate at work. Therefore, a noise reduction device for a hydraulic press is proposed.

[0003] For example, a Chinese patent with publication number CN213227722U discloses a noise reduction device for a hydraulic press, which includes a pipeline connecting mechanism and a pipeline fixing mechanism, wherein the pipeline connecting mechanism connects two hydraulic pipelines, the pipeline fixing mechanism is arranged on the side wall of the hydraulic press, and the pipeline fixing mechanism is fixedly connected to the hydraulic pipeline, the pipeline fixing mechanism includes a fixing seat, a connecting assembly and an elastic mounting assembly, the fixing seat is arranged on the side wall of the hydraulic press, the connecting assembly is arranged on the fixing seat, the elastic mounting assembly is arranged on the connecting assembly, and the hydraulic pipeline is fixedly connected to the elastic mounting assembly.

[0004] The existing technical documents have the following problems:

[0005] The existing technical documents have some shortcomings when used, such as: the traditional oil hydraulic machine noise reduction equipment is to add noise reduction materials, because the oil hydraulic machine is easy to produce oil stains during operation, which will corrode the noise reduction layer, thereby reducing the effect and service life of the noise reduction material, and during the operation of the oil hydraulic machine, the impact will cause huge pressure on the equipment support frame, and it is easy to damage the support frame under long-term operation, which is not conducive to the normal operation of the oil hydraulic machine. In view of this, we propose a noise reduction device for oil hydraulic machines. Utility Model Content
