Abstract
The utility model discloses a double - circuit hydraulic press, including frame, stand, frame and hydraulic cylinder, hydraulic cylinder fixes in the frame, the frame is by four stands and frame reciprocal anchorage, hydraulic cylinder upper portion bilateral symmetry is connected with oil pipe respectively, hydraulic cylinder lower part bilateral symmetry is connected with down oil pipe respectively, the last oil pipe of hydraulic cylinder and both sides and being connected through magenetic exchange valve between the oil pipe down, be equipped with into oil pipe and time oil pipe about the position of magenetic exchange valve below respectively, advance oil pipe and return oil pipe and hydraulic connection. The utility model discloses all be equipped with oil pipe and lower oil pipe in hydraulic cylinder's both sides for whole hydraulic press rises to press high height, and pressure is moderate, and the suppression area is bigger, and application range is wider, also makes the stationarity of whole hydraulic press better, in addition, every oil pipe department all is equipped with the filter screen, impurity in the filtering oil for the life of hydraulic press is longer.
Description
Technical field
The utility model belongs to hydraulic press field, relates 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.
Utility model content
The purpose of this utility model is to provide a kind of and suppresses that area is large, the two-way hydraulic press of moderate pressure.
The utility model 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 utility model 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 utility model.
Detailed description of the invention
As shown in Figure 1, the utility model 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 the technical solution of the utility model and utility model design thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the utility model.
