The hydraulic station can satisfy the requirement of the hydraulic control of a large tonnage and large cavity diamond press, and the utility model has the advantages of high integration of hydraulic parts, order and beautiful structural configuration, large flow of hydraulic oil, little pressure loss, low noise, reliable work, easy adjustment and maintenance, etc.

Description

The hydraulic station of large-tonnage cubic apparatus diamond press
Technical field:
The utility model belongs to the hydraulics field, especially for the hydraulic station of large-tonnage cubic apparatus diamond press.
Background technique:
Hydraulic station is the match equipment of cubic apparatus diamond press, along with the continuous progress of synthetic diamond synthetic technology and the continuous development of diamond industry, each diamond enterprise constantly develops big cylinder diameter, large-tonnage diamond press, because the increasing of cylinder diameter, former medium and small tonnage press hydraulic station can not adapt to the usage requirement of great tonnage press, and mainly there is following problem in it:
(1) hydraulic pipe line and valve member latus rectum are less than normal, cause underfed, make the main frame action carry out slower.
(2) each hydraulic valve piece is installed in respectively on six valve plates, and each valve plate is connected by pipeline because the pipeline that connects is many, easily produce leak outside and the hydraulic shock pressure loss big, so poor reliability.
(3) because valve plate is installed dispersion, and pipeline is more, be not easy to maintenance.
Summary of the invention:
The purpose of this utility model provides a kind of hydraulic control needs that can satisfy large-tonnage, big cavity diamond press, has hydraulic parts level of integration height, and hydraulic fluid flow rate is big, and the pressure loss is little, the large-tonnage cubic apparatus diamond press hydraulic station of good reliability.
Realize that the technological scheme that the purpose of this utility model is taked is: the main feature of this large-tonnage cubic apparatus diamond press hydraulic station is that all hydraulic valve member is concentrated on two valve plates, connect by an oil pipe between two valve plates, wherein, three valve members are installed on the valve plate 1, be to constitute by two solenoid valves and relief valve, a solenoid valve is used to control the break-make of two seven logical valves, and the remote control mouth of another electromagnetic valve relief valve makes when press quits work and can make the oil pump off-load.On valve plate 2, concentrate 25 control valve members such as the one-way valve that is used to finish the main frame everything, selector valve, throttle valve are housed, and by the Solenoid ball valve on the valve plate, pressurized machine, Pilot operated check valve, valve members such as solenoid directional control valve constitute unpowered pressure release work step.
The large-tonnage cubic apparatus diamond press hydraulic station of making according to such scheme.It can satisfy the hydraulic control needs of large-tonnage, big cavity diamond press, compared with prior art, has hydraulic parts level of integration height, the topology layout neat appearance, hydraulic fluid flow rate is big, and the pressure loss is little, noise is low, and reliable operation is easy to advantages such as adjustment and maintenance.
Utilize accompanying drawing to further describe embodiment of the present utility model below.
Description of drawings:
Fig. 1 is a hydraulic station schematic representation of the present utility model.
Embodiment:
Referring to Fig. 1, hydraulic station of the present utility model concentrates on all hydraulic valve on two valve plates, wherein, three valve members are installed on the valve plate 1, be to constitute by two two-position four-way solenoid valves 16,40 and relief valve 41, two-position four-way solenoid valve 16 is used to control the break-make of two seven logical valves 7, and the remote control mouth of two-position four-way solenoid valve 40 control relief valves 41 makes when press quits work and can make the oil pump off-load.
25 control valve members have been installed on No. 2 valve plates, are to be made of one-way valve 8~13, solenoid directional control valve 19~24, throttle valve 25~30 and solenoid valve 17,33,36,37, one-way valve 34,48, throttle valve 35.Wherein, 8~13 valve members adopt the ultrahigh pressure Pilot operated check valve, and its effect is to isolate super high pressure oil, guarantees not cause under the superpressure packing state super high pressure oil to enter low service system; 19~24 valve members adopt the two-position four-way solenoid directional control valve, by six clutch release slave cylinder actions of its control; 25~30 valve member is a throttle valve, adjust the movement speed of six clutch release slave cylinders by it: 17 is the two-position four-way solenoid directional control valve, reverse break-make by its control ultrahigh pressure Pilot operated check valve, switch at quick return work step 12CT, 17 valve events are opened the ultrahigh pressure Pilot operated check valve and are made clutch release slave cylinder cavity of resorption oil realize quick return by oil sump tank; 33,37 is two 3-position 4-way solenoid directional control valves, and their idle runnings that can realize press that matches with other valve are advanced work steps such as topping up, superpressure, quick return; Be connected by an oil pipe between valve plate 1 and the valve plate 2, make in the whole hydraulic station pipeline less.Be to strengthen the latus rectum of working connection, increased the latus rectum of four valve members such as 33,35,37,41, guarantee to have enough oil masses to supply with main frame, and change its oil-feed into the internal system fuel feeding by oil pump, realized unpowered pressure release.Unpowered pressure release work step is by the Solenoid ball valve on the valve plate 36, pressurized machine 15, Pilot operated check valve 34, throttle valve 35, and 3-position 4-way solenoid directional control valve 37 valve members such as grade constitute, and wherein, throttle valve 35 adopts the throttle valve of band one-way valve.When carrying out the pressure release work step, Solenoid ball valve 36 energisings, pressurized machine 15 cavity of resorption pressure oils are opened Pilot operated check valve 34 by 36 valves, and like this, pressurized machine 15 cavity of resorption pressure oils promptly flow back to fuel tank by the 35-34-37 valve member.Need not start oil pump in the whole pressure leak process, but provide power, finish the pressure release work step, like this, both save the energy, simultaneously, reduce ambient noise again by the internal pressure in the press pressure maintaining period.Fluid also is installed on the hydraulic station return line is pressed oil cooler, under the ambient temperature conditions of higher, can utilize this device to reduce the oil temperature, guarantee the press proper functioning.
