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; It needs to be manually moved to a certain position, which is time-consuming and laborious

Embodiment Construction
[0010] like figure 1 As shown, the present invention provides a rotatable two-way hydraulic press, comprising a machine base 1, a frame 2 and a hydraulic cylinder 4, the hydraulic cylinder 4 is fixed on the frame 2, and the frame 2 is formed by a rotating column 3 and the base 1 are fixed to each other, the upper part of the hydraulic cylinder 4 is symmetrically connected with upper oil pipes 5 respectively, and the lower part of the hydraulic cylinder 4 is respectively connected with lower oil pipes 6 symmetrically, and the hydraulic oil cylinder 4 is connected with the upper oil pipes 5 on both sides. It is connected with the lower oil pipe 6 through an electromagnetic reversing valve 7. An oil inlet pipe 8 and an oil return pipe 9 are respectively arranged on the left and right below the electromagnetic reversing valve 7. The oil inlet pipe 8 and the oil return pipe 9 are connected with the hydraulic cylinder 4.

The invention discloses a rotatable type two-way hydraulic press. The rotatable type two-way hydraulic press comprises an engine base, a rack and a hydraulic oil cylinder. The rotatable type two-way hydraulic press is characterized in that the hydraulic oil cylinder is fixed on the rack; the rack is formed by mutually fixing a rotary stand column and the engine base; upper oil tubes are connected on the upper part of the hydraulic oil cylinder respectively in a bilaterally symmetrical mode; lower oil tubes are connected on the lower part of the hydraulic oil cylinder respectively in the bilaterally symmetrical mode; the hydraulic oil cylinder is connected with the upper oil tubes and the lower oil tubes at the two sides by a solenoid directional valve; an oil inlet tube and an oil return tube are respectively arranged on positions below the solenoid directional valve bilaterally; and the oil inlet tube and the oil return tube are connected with the hydraulic oil cylinder. The upper oil tubes and the lower oil tubes are arranged on both sides of the hydraulic oil cylinder, so that the whole hydraulic press is large in pressure-rising height, moderate in pressure, larger in pressing area, wider in range of application and better in stability; mover, each oil tube is provided with a filter screen for filtering impurities in oil, so that the service life of the hydraulic press is longer; besides, the hydraulic press can rotate at random, can normally work without being limited by a narrow space, and is time-saving and labor-saving due to the fact that manual movement is not required.
Description
technical field [0001] The invention belongs to the field of hydraulic machines and relates to a rotatable two-way 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; It needs to be manually moved to a certain position, which is time-consuming and labor-intensive. Contents of the invention [0003] The object of the present invention is to provide a rotatable two-way hydraulic press with large pressing area and moderate pressure. [0004] The present inventi...
