[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] Such as figure 1 As shown, the present invention provides a rotatable single-channel hydraulic machine, comprising a base 1, a frame 2 and a hydraulic cylinder 4, the hydraulic cylinder is fixed on the frame 2, and the frame 2 is formed by a rotating column 3 and the machine base 1 are fixed to each other, the upper side of the hydraulic cylinder 4 is connected to the upper oil pipe 5, the lower part of the hydraulic cylinder 4 is connected to the lower oil pipe 6 on the same side as the upper oil pipe, and the hydraulic cylinder 4 is connected to the oil pipe on both sides. The upper oil pipe 5 and the lower oil pipe 6 are connected by an electromagnetic reversing valve 7, and the position below the electromagnetic reversing valve 7 is provided with an oil inlet pipe 8 and an oil return pipe 9, and the oil inlet pipe 8 and the oil return pipe 9 are connected to the hydraulic cylinder 4 .
[0011] Wherein, each oil pipe is provided with a filter screen 10 to filter out...

The invention discloses a rotary one-way hydropress. The rotary one-way hydropress comprises a stand, a frame and a hydraulic oil cylinder, wherein the hydraulic oil cylinder is fixed on the frame; the frame is mutually fixed with the stand by a rotating stand column; one side of the upper part of the hydraulic oil cylinder is connected with an upper oil pipe; the lower part of the hydraulic oil cylinder is connected with a lower oil pipe at the same side with the upper oil pipe; the hydraulic oil cylinder is connected with the upper oil pipe and the lower oil pipe through an electromagnetic reversing valve; and an oil inlet pipe and an oil return pipe are arranged below the electromagnetic reversing valve, and are connected with the hydraulic oil cylinder. As the upper oil pipe and the lower oil pipe are arranged at one side of the hydraulic oil cylinder, the pressure rising height of the whole hydropress is high, the pressure is proper, the pressing area is larger, the use range is wider, and the stability of the whole hydropress is better; in addition, each oil pipe is provided with a filter screen for filtering away impurities in oil, so that the service life of the hydropress is longer; and in addition, the hydropress can randomly rotate, can normally work without being limited by narrow space, and has no need to be carried by persons to save both time and labor.
Description
technical field [0001] The invention belongs to the field of hydraulic machines and relates to a rotatable single-channel 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 single-channel hydraulic press with large pressing area and moderate pressure. [0004] The p...
