Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of hydraulic press fast decompression valve block control system, is characterized in that, working connection accesses press master cylinder active chamber, through master control cartridge valve 3 oil return T1 mouth to fuel tank by the P mouth of valve block; Pilot control oil circuit is oily by P mouth, through one-way valve 6, throttle valve 7, one-way throttle valve 4 acts on the control chamber to master control cartridge valve 3, and the oil extraction of control chamber is showed by T2 cause for gossip; YA11 electromagnetic direction valve 5 obtains electric, and YA12 electromagnetic direction valve 10 dead electricity is slide block working state; YA11 electromagnetic direction valve 5 dead electricity, YA12 electromagnetic direction valve 10 obtains electric, control guide's cartridge valve 11 and unload deglitch pressure by the opening of adjustment self and responsible the stablizing of the opening of one-way throttle valve 4, control guide's cartridge valve 12 afterwards and follow opening and all opening of the directional control valve 9 that surges, master control cartridge valve 3 is all opened and realizes large discharge quick pressure releasing; When slide block needs quick pressure accumulation, YA11 electromagnetic direction valve 5 obtains electric, YA12 electromagnetic direction valve 10 dead electricity, then realize X point external control oil and closed by master control cartridge valve 3 rapidly.
Working procedure of the present utility model and working principle are: this valve block P chamber is connected with slide block cylinder efficient chamber, when the first conducting magnetic iron of control YA11 obtains electric, control cartridge valve and enter packing state.
The operating pressure of directional control valve 9 of surging can set, when compacting completes, YA11 dead electricity, now P point pressure is more than setup pressure value, low-pressure pilot cartridge valve 12 is closed, and spike pressure guide cartridge valve 11 is opened, and can realize slowly and the main Cartridge inserted valve integrated block 3 of trace unlatching release by regulating the adjustable lever of unidirectional shutoff valve 4 and guide's cartridge valve 12 self, object sheds high pressure stably, avoids energy to discharge suddenly the vibrations of generation.
Be down to when P point pressure and below setup pressure value be, the directional control valve that surges resets, and low-pressure pilot controls cartridge valve 12 and opens, and the control chamber fluid of the main Cartridge inserted valve integrated block 3 of release is all shed by guide's cartridge valve 11,12, therefore all open, realize the compressed oil that large discharge sheds cylinder efficient chamber.
When pressure unsnatch need to be transformed into working state time, YA11 electromagnetic direction valve 5 electricly can again main for release cartridge valve 3 to be closed.Consider that now P point pressure is general lower, provides a road guide oil from X point, YA12 electromagnetic direction valve 5 obtains electric, and main for release Cartridge inserted valve integrated block 3 can be closed rapidly by one-way valve 8, one-way throttle valve 4 by pressure oil.
The utility model is applicable to high speed forging hydraulic press or the hydraulic system to the short especially general forge hot hydraulic press of venting duration requirement, decrease press slide compacting and be transformed into backhaul to the time of suppressing again, improve working efficiency, decrease heated work pieces and expose the aerial time, achieve the target of energy-saving and emission-reduction.
This valve block has highly versatile, the functions such as directional control valve pressure can set, release speed stepwise adjustable of surging, and flexible, Applicable scope is wider.When productive temp requires strict, or by condition limit X place external control pressure oil cannot be additionally provided time, native system still can realize the object of quick pressure releasing, is slightly slow in the transfer process of pressure release and pressure accumulation.Now oil circuit control is hedged off from the outer world by one-way valve 1,2,6,8 automatically, and YA12 electromagnetic direction valve 10 is ineffective, but hydraulic oil can not be made to be leaked by X place.
The above is only to preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
