Abstract
The invention discloses an automatic lifting type double-path hydraulic machine. The machine comprises a machine seat, a rack and a hydraulic oil cylinder; the hydraulic oil cylinder is fixed to the rack, and four lifting stand columns are fixed to the machine seat to form the rack; a motor for controlling the lifting stand columns is arranged in the rack; upper oil pipes are connected to the upper portion of the hydraulic oil cylinder in a bilateral symmetry manner, and lower oil pipes are arranged on the lower portion of the hydraulic oil cylinder in a bilateral symmetry manner; the hydraulic oil cylinder is connected with the upper oil pipes and the lower oil pipes on the two sides of the hydraulic oil cylinder through electromagnetic reversing valves, and oil inlet pipes and oil returning pipes are arranged on the left sides and the right sides of the positions below the electromagnetic reversing valves; and the oil inlet pipes and the oil returning pipes are connected with the hydraulic oil cylinder. The upper oil pipes and the lower oil pipes are arranged on the two sides of the hydraulic oil cylinder, and the whole hydraulic machine is high in pressure rising height, moderate in pressure, larger in pressing area, wider in use range and better in stability; in addition, each oil pipe is provided with a filter net so as to filter out impurities in oil, and the service life of the hydraulic machine is longer; in addition, the hydraulic machine can be controlled by the motor to ascend and descend, and cannot be limited by height, so that the hydraulic machine can normally work, and is not required to be manually carried out; time and labor are saved, and the hydraulic machine can adapt to different heights, and is wider in working face.
Description
Technical field
The invention belongs to hydraulic press field, relate to a kind of automatic-lifting type 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; In addition, hydraulic press operationally, exists sometimes because the problem of height, hydraulic press cannot be worked fully, also need manually to go to move or set up some equipment and could arrive certain position, waste time and energy.
Summary of the invention
Area is large, moderate pressure, lifting automatic two-way hydraulic press easily to the object of the present invention is to provide one to suppress.
The present invention is for solving the problems of the technologies described above by the following technical solutions: a kind of automatic-lifting type two-way hydraulic press, comprise support, frame and hydraulic jack, described hydraulic jack is fixed in frame, described frame is interfixed by four lifting columns and support, and described frame is provided with the motor of the lifting column of control; 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, be respectively equipped with oil inlet pipe and oil return pipe 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.
Further improvement, described lifting column is made up of cylinder and the lifting shaft be arranged on cylinder.
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 operating efficiency is improved greatly, 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; In addition, this hydraulic press is elevated by Electric Machine Control, and can not be restricted because of height, normally cannot work, also do not need people to go to move, time saving and energy saving, make the different height that can adapt to of hydraulic press, working face is wider.
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 automatic-lifting type two-way hydraulic press, comprise support 1, frame 2 and hydraulic jack 4, described hydraulic jack 4 is fixed in frame 2, described frame 2 is interfixed by four lifting columns 3 and support 1, and described frame 2 is provided with the motor 11 of the lifting column 3 of control; Described hydraulic jack 4 top is symmetrical is connected to oil pipe 5, described hydraulic jack 4 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 4 and both sides and lower oil pipe 6, be respectively equipped with oil inlet pipe 8 and oil return pipe 9 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.
Wherein, be equipped with screen pack 10 at each oil pipe place, the impurity in filtering oil, make the longer service life of hydraulic press.
Wherein, described lifting column 3 is made up of cylinder 31 and the lifting shaft 32 be arranged on cylinder 31, and lifting shaft 32 is connected with frame 2 and drives a lifting.
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.
