Problems solved by technology

[0002] Hydraulic presses are widely used in the field of machinery manufacturing. The hydraulic presses in the prior art have a large pressing area and a large stroke. Small tonnage hydraulic presses have a small pressing area and a small stroke. None of the hydraulic presses has a large pressing area, but the stroke should be small and the pressure should be small. , if the pressure is too high, it will have a certain impact on the oil pipe, the oil pipe is easy to burst, and the hydraulic cylinder is also easy to be damaged

Abstract

The invention discloses a hydraulic machine, comprising a machine seat, vertical columns, a machine frame and a hydraulic cylinder, wherein the hydraulic cylinder is fixed on the machine frame; the machine frame and the machine seat are mutually fixed by four vertical columns; the upper part of the hydraulic cylinder is connected with an upper oil pipe, and the lower part of the hydraulic cylinder is connected with a lower oil pipe; the hydraulic cylinder is connected with the upper oil pipe and the lower oil pipe by an electromagnetic reversing valve; and an oil inlet pipe and an oil outlet pipe are arranged below the electromagnetic reversing valve and are connected with the hydraulic cylinder. The hydraulic machine has the advantages of high pressing height, moderate pressure and large pressing area.

Description

technical field [0001] The invention relates to a hydraulic machine. Background technique [0002] Hydraulic presses are widely used in the field of machinery manufacturing. The hydraulic presses in the prior art have a large pressing area and a large stroke. Small tonnage hydraulic presses have a small pressing area and a small stroke. None of the hydraulic presses has a large pressing area, but the stroke should be small and the pressure should be small. , If the pressure is too high, it will have a certain impact on the oil pipe, the oil pipe is easy to burst, and the hydraulic cylinder is also easy to be damaged. Therefore, it is necessary to provide a new technical solution to solve the above technical problems. Contents of the invention [0003] The object of the present invention is to provide a hydraulic press with large pressing area and moderate pressure. [0004] The technical scheme adopted in the present invention is: [0005] A hydraulic machine, comprisin...
