Abstract
The utility model relates to an independent hydraulic circuit who mends oil falls in hydraulic pressure high -speed forging machine idle running soon is equipped with the pipeline between main hydraulic cylinder and oil tank to set up the unloader valve on this pipeline, with the pressure among the quick reduction main hydraulic cylinder, be equipped with the prefill valve on the connecting tube between main hydraulic cylinder and the pressure -loaded prefilling tank, the hydraulic oil in the pressure -loaded prefilling tank is the voltol oil. The low oil pressure is quick during the oil pressure in the pressure -loaded prefilling tank in main hydraulic cylinder independently mends oil to main hydraulic cylinder. Change the working method that traditional hydraulic circuit mended oil by pressure -loaded prefilling tank and hydraulic pump simultaneously, avoided owing to inhale in vain the speed that causes to wait the shortcoming slowly, realized system energy saving, stability, efficient beneficial effect simultaneously.
Description
Technical field
This utility model is related to a kind of hydraulic circuit of independent repairing, more particularly to a kind of using the main hydraulic pressure for reclaiming storage
Cylinder pressure release hydraulic oil, to the hydraulic circuit of main hydraulic cylinder repairing, belongs to hydraulic transmission technology neck when hydraulic rapid forging press idle running drops soon
Domain.
Background technology
Soon during drop, the mode of repairing is usually main pump and topping up to known hydraulic rapid forging press idle running in main hydraulic cylinder
Tank is supplied simultaneously, and realizes that idle running drops soon.On the one hand due to using main pump repairing, larger energy need to be consumed, bring and produce into
This increase；On the other hand because replenishing valve could be opened to master cylinder repairing when master cylinder oil pressure is less than pressure-loaded prefilling tank oil pressure, because
The flow of repairing can not fully meet the oil mass of supplement needed for main hydraulic cylinder during idle running drops soon, and Jing " being emptied " often occurs now
As.Adverse effect：One is that the speed for causing idle running to drop soon does not reach requirement, and two cause hydraulic rapid forging press itself
Shake, generation is unstable, uneven, or even causes master cylinder to clash into, and three is to cause tup to shake and affect control effect.In order to gram
Take drawbacks described above, it is desirable to have it is a kind of can reclaim storage by hydraulic oil during main hydraulic cylinder backhaul is preferably with pressure, again can be
The apparatus and method that the novel hydraulic loop of main hydraulic cylinder repairing is released to when idle running drops soon come out.
The content of the invention
This utility model provides the hydraulic circuit that independent repairing drops soon in a kind of hydraulic rapid forging press idle running, and it is fast that it realizes hydraulic pressure
The independent purpose to main hydraulic cylinder repairing of pressure-loaded prefilling tank during the fast drop of forging machine idle running.
To achieve these goals, this utility model Bian takes technical scheme below enforcement：Soon drop is only for hydraulic rapid forging press idle running
The hydraulic circuit of vertical repairing, it is included：Hydraulic pump, check valve, electro-hydraulic proportional valve, replenishing valve, feather valve, main hydraulic cylinder, backhaul
Hydraulic cylinder, walking beam, tup, pressure-loaded prefilling tank, air valve and fuel tank,
Feather valve is provided between the main hydraulic cylinder and the fuel tank；
The pressure-loaded prefilling tank of the main hydraulic cylinder repairing is designed to high-pressure liquid-filling tank；
Pipeline between the pressure-loaded prefilling tank and main hydraulic cylinder is provided with replenishing valve；
Pressure in the pressure-loaded prefilling tank is between 1~3Mpa.
The design has that energy-conservation, repairing speed are fast, repairing amount is big, hydraulic system fast response time, avoid " being emptied ", equipment
Operate steadily, the advantages of stable operation is reliable, production cost is reduced.
Description of the drawings
Fig. 1 is this utility model hydraulic circuit diagram.
In the accompanying drawings：1 be hydraulic pump, 2, for check valve, 3,8,10 be electro-hydraulic proportional valve, 4 be main hydraulic cylinder, 5 be backhaul
Hydraulic cylinder, 6 be moved cross beam, 7 be tup, 9 be feather valve, 11 be replenishing valve, 12 be pressure-loaded prefilling tank, 13 be air valve.
Specific embodiment
Explanation is further explained to this utility model below in conjunction with accompanying drawing：
Accompanying drawing for hydraulic rapid forging press hydraulic circuit diagram, mark in figure hydraulic pump 1, check valve 2, electro-hydraulic proportional valve 3,
, 8th, 10 main hydraulic cylinder 4, backhaul hydraulic cylinder 5, moved cross beam 6, tup 7, feather valve 9, replenishing valve 11, pressure-loaded prefilling tank 12, air valve 13
Annexation.Pipeline is wherein provided between main hydraulic cylinder 4 and fuel tank, and feather valve 9 is provided with the pipeline；Main hydraulic cylinder 4
Replenishing valve 11 is provided with the connecting pipe between pressure-loaded prefilling tank 12, the hydraulic oil in pressure-loaded prefilling tank 12 is hydraulic oil.It is above-mentioned to be set to
The designing points of the present invention, repairing when being dropped soon to hydraulic rapid forging press idle running by pressure-loaded prefilling tank 12 is independent, change conventional hydraulic loop
By the working method of pressure-loaded prefilling tank 12 and hydraulic pump 1 repairing simultaneously, it is to avoid the shortcomings of speed that causes due to being emptied is slow, while
Realize energy saving of system, stable, efficient beneficial effect.
When hydraulic rapid forging press needs idle running to drop soon, being first turned on feather valve 9 makes the oil pressure of main hydraulic cylinder 4 be less than pressure-loaded prefilling tank 12
Oil pressure, replenishing valve 11 automatically opens up rapidly, and moved cross beam 6 drives tup 7 to decline rapidly, and backhaul hydraulic cylinder 5 declines therewith, electricity
Liquid proportional valve 10 is opened, and the oily ftercompction in the rod chamber of backhaul hydraulic cylinder 5 enters pressure-loaded prefilling tank 12；When tup 7 contacts workpiece, electro-hydraulic ratio
Example valve 3 is opened, and Main Hydraulic Pump 1 to the fuel feeding of main hydraulic cylinder 4, the oil pressure of main hydraulic cylinder 4 are raised immediately, and replenishing valve 11 is automatically switched off.
Pressure in this utility model in pressure-loaded prefilling tank 12 supplements press-in topping up except the oil in the above-mentioned rod chamber of backhaul hydraulic cylinder 5
Outside tank 12, two aspects also come：1st, air valve 13 is opened by outside gases at high pressure supplementary pressure：2nd, during 4 backhaul of main hydraulic cylinder,
The pressure oil for opening the intracavity of 8 main hydraulic cylinder of electro-hydraulic proportional valve 4 is supplemented in press-in pressure-loaded prefilling tank 12.
