Abstract
The invention discloses a two-way hydraulic machine, which comprise a machine seat, upright posts, a rack and a hydraulic cylinder, wherein the hydraulic cylinder is fixed to the rack; the rack is mutually fixed with the machine seat by four upright posts; the left and the right of the upper part of the hydraulic cylinder are symmetrically and respectively connected with upper oil pipes; the left and the right of the lower part of the hydraulic cylinder are symmetrically and respectively connected with lower oil pipes; the hydraulic cylinder are connected with the upper oil pipes and the lower oil pipes at two sides by solenoid directional valves; oil inlet pipes and oil return pipes are bilaterally and respectively arranged at the positions below the solenoid directional valves; and the oil inlet pipes and the oil return pipes are connected with the hydraulic cylinder. According to the invention, the upper oil pipes and the lower oil pipes are arranged at two sides of the hydraulic cylinder, so that the rising height of the whole hydraulic cylinder is high, the pressure is moderate, the pressing area is larger, the usage range is wider, and the stability of the whole hydraulic machine is better; in addition, a filter screen is arranged at each oil pipe, so that impurities in oil can be filtered off, and the service life of the hydraulic machine is longer.
Description
Technical field
The invention belongs to hydraulic press field, relate to a kind of two-way hydraulic press.
Background technology
Hydraulic press is very wide in mechanical manufacturing field application, the hydraulic press compacting area of prior art is large, and stroke is also large, and the hydraulic press compacting area of little tonnage is little, stroke is also little, do not have a kind of hydraulic press to suppress area large, but stroke is little, pressure is little, if pressure is excessive, can produce certain impact to oil pipe, oil pipe easily bursts, and hydraulic jack is also easily impaired.Therefore, need to carry
Above-mentioned technical problem is solved for a kind of new technical scheme.
Summary of the invention
The object of the present invention is to provide and a kind ofly suppress that area is large, the two-way hydraulic press of moderate pressure.
The present invention is for solving the problems of the technologies described above by the following technical solutions: a kind of two-way hydraulic press, comprise support, column, frame and hydraulic jack, described hydraulic jack is fixed in frame, described frame is interfixed by four columns and support, described hydraulic jack top is symmetrical is connected to oil pipe, described hydraulic jack bottom is symmetrical is connected to lower oil pipe, be connected by solenoid directional control valve between the upper oil pipe of described hydraulic jack and both sides and lower oil pipe, oil inlet pipe and oil return pipe is respectively equipped with about described solenoid directional control valve lower position, described oil inlet pipe is connected with hydraulic jack with oil return pipe.
Further improvement, described described upper oil pipe, lower oil pipe, oil inlet pipe and oil return pipe place are equipped with screen pack.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
On the both sides of hydraulic jack are all provided with, oil pipe and lower oil pipe, make whole hydraulic press play pressure highly high, moderate pressure, and compacting area is larger, and the scope of application is wider, also makes the stationarity of whole hydraulic press better; In addition, each oil pipe place is provided with screen pack, and the impurity in filtering oil makes the longer service life of hydraulic press.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the invention provides a kind of two-way hydraulic press, comprise support 1, column 2, frame 3 and hydraulic jack 4, described hydraulic jack 4 is fixed in frame 3, described frame 1 is interfixed by four columns 2 and support 1, described hydraulic jack 4 top is symmetrical is connected to oil pipe 5, described hydraulic jack bottom is symmetrical is connected to lower oil pipe 6, be connected by solenoid directional control valve 7 between the upper oil pipe 5 of described hydraulic jack and both sides and lower oil pipe 6, oil inlet pipe 8 and oil return pipe 9 is respectively equipped with about described solenoid directional control valve 7 lower position, described oil inlet pipe 8 is connected with hydraulic jack 4 with oil return pipe 9.
Be improved further, be equipped with screen pack 10 at each oil pipe place, the impurity in filtering oil, make the longer service life of hydraulic press.
For those of ordinary skills, can be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the present invention.
Claims (2)
