Abstract
The utility model discloses a hydraulic press. The hydraulic press comprises a machine base, upright columns, a machine frame and a hydraulic oil cylinder, wherein, the hydraulic oil cylinder is fixed on the machine frame; the machine frame is formed by mutually fixing four upright columns and the machine base; an upper oil pipe is connected to the upper part of the hydraulic oil cylinder, and a lower oil cylinder is connected to the lower part of the hydraulic oil cylinder; the hydraulic oil cylinder is connected with the upper and the lower oil pipes through an electromagnetic reversing valve; and an oil inlet pipe and an oil return pipe, which are arranged below the electromagnetic reversing valve, are connected with the hydraulic oil cylinder. The hydraulic press has the advantages of high pressure start height, moderate pressure and large pressing area.
Description
Technical field
The utility model relates to a kind of hydraulic press.
Background technology
Hydraulic press is used very wide in mechanical manufacturing field, the hydraulic press compacting area of prior art is big, and stroke is also big, and the hydraulic press compacting area of little tonnage is little, stroke is also little, do not have a kind of hydraulic press compacting area big, but stroke is little, pressure is little, if pressure is excessive, can produce certain influence to oil pipe, the easy explosion of oil pipe, hydraulic jack is also impaired easily.Therefore, need provide a kind of new technical scheme to solve above-mentioned technical problem.
The utility model content
The purpose of this utility model provides a kind ofly suppresses that area is big, the hydraulic press of moderate pressure.
The technical solution adopted in the utility model is:
A kind of hydraulic press, comprise support, column, frame and hydraulic jack, described hydraulic jack is fixed on the frame, described frame is interfixed by four columns and support, it is characterized in that: described hydraulic jack top is connected with oil pipe, and described hydraulic jack bottom is connected with down oil pipe, is connected by solenoid directional control valve between described hydraulic jack and last oil pipe and the following oil pipe, described solenoid directional control valve lower position is provided with oil inlet pipe and oil return pipe, and described oil inlet pipe is connected with hydraulic jack with oil return pipe.
Described oil pipe, following oil pipe, oil inlet pipe and the oil return pipe place of going up is equipped with filter.
The utility model has the advantages that: it is highly high to play pressure, moderate pressure, and the compacting area is big.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, support, 2, column, 3, frame, 4, hydraulic jack, 5, go up oil pipe, 6, oil pipe down, 7, solenoid directional control valve, 8, oil inlet pipe, 9, oil return pipe, 10, filter.
