Embodiment
Below in conjunction with accompanying drawing and embodiment model utility is done detailed explanation:
The purpose of the utility model provides a kind of guillotine shear and uses hydraulic valve bank, and it adopts threaded cartridge valve, makes the valve of not being with valve body be arranged in the hole of valve piece, through the inner passage in the valve piece, makes between these valves and communicates with each other, thereby reach various control effects.
As a kind of specific embodiment of the utility model; The utility model provides like Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of guillotine shear shown in Figure 5 and uses hydraulic valve bank; Comprise two logical screw-in cartridge valves 1, pressure valve 2, solenoid directional control valve, ball valve, equilibrium valve 8 and main valve body 12, said pressure valve 2 is arranged on main valve body 12 sides, and said two logical screw-in cartridge valves 1, first segment discharge orifice 9 and second throttle orifice 10 are arranged in the main valve body 12; Said first solenoid directional control valve 3 is arranged on pressure valve 2 sides; Said first ball valve 6 and second ball valve 7 are arranged side by side on main valve body 12, and this patent ball valve can be Solenoid ball valve, also can adopt other forms of ball valve; Producer can select as required; Said second solenoid directional control valve 4 and the 3rd solenoid directional control valve 5 are arranged on the main valve body 12, and the 3rd solenoid directional control valve 5 is arranged on first ball valve 6 and second ball valve, 7 one sides, and said safety valve 11 is arranged between the 3rd solenoid directional control valve 5 and the main valve body 12; Thereby improved the Security of entire equipment greatly, said equilibrium valve 8 is arranged on main valve body 12 1 sides.
The concrete pressure control of this patent is following:
Start Oil pump electrical machinery earlier,, come the maximum pressure of controlled hydraulic system by pressure valve 2 or proportional pressure valve control two-way plug-in valve 1 according to required shearing force; Because only when shearing; The slide block hydraulic system that meets obstructions just can produce pressure, and the also corresponding increase along with the needs of shearing force of pressure, so its pressure is main with the needs that satisfy shearing force also; So as long as set pressure maximum; Afterwards again through first solenoid directional control valve, 3 dead electricity, make the whole system off-load, can accomplish whole operation.
Figure is as shown in Figure 6 for this patent oil circuit, its concrete control as follows:
1, the binder cylinder clamps;
Y1 end through first solenoid directional control valve 3 and the Y2 of the 3rd solenoid directional control valve 5 hold; The pressure oil that makes oil pump get passes through one-way valve to the three solenoid directional control valves 5, and (P → B) the D mouth to the valve piece arrives the binder cylinder again; Make the binder cylinder overcome the spring force piston and stretch out, make the sheet material that is sheared clamped.
2, shear control;
Shear: get through the Y1 end of first solenoid directional control valve 3, the Y3 end of second solenoid directional control valve 4 and the Y2 of the 3rd solenoid directional control valve 5; Make that (P → A) arrives the epicoele (rodless cavity) of master cylinder again to valve group A mouth through second solenoid directional control valve 4 for pressure oil that oil pump gets; The fluid row of the cavity of resorption of master cylinder (rod chamber) is to the epicoele that attaches oil cylinder (small oil tank) (rodless cavity); Attaching the fluid of the cavity of resorption (rod chamber) of oil cylinder arranges to the B of valve group mouth; (the T mouth that B → T) arrives the valve piece again is oil sump tank again, so that whole slide block down is sheared then to pass through equilibrium valve 8 to second solenoid directional control valves 4 again.
If the guillotine shear slide block only is a null up and down, then the master cylinder epicoele can't produce pressure, and the pressure oil of auxilliary oil cylinder cavity of resorption only is to overcome the pressure that equilibrium valve 8 sets and discharge according to required.If guillotine shear is in shearing condition, then the master cylinder epicoele can produce pressure, and pressure oil is opened equilibrium valve 8 through equilibrium valve 8 control ports, makes the pressure oil non-resistance of auxilliary oil cylinder cavity of resorption discharge.
Return, binder cylinder unclamp: the Y4 of the Y1 of first solenoid directional control valve 3 end and second solenoid directional control valve 4 holds; The pressure oil that oil pump is got is through second solenoid directional control valve 4 (P → B) arrive valve piece B mouth again to equilibrium valve 8 to arrive auxilliary oil cylinder cavity of resorption again; The fluid row of small oil tank epicoele is to the master cylinder cavity of resorption; (A → T) passes through the T mouth oil return of valve piece to the fluid of master cylinder epicoele again, thereby makes slide block up to second solenoid directional control valve 4 through valve group A mouth.
3, angle of shear adjustment;
The angle of shear increases: the Y6 of the Y1 end of first solenoid directional control valve 3, the Y4 end of second solenoid directional control valve 4 and second ball valve 7 holds; The pressure oil that oil pump is got is through second solenoid directional control valve 4 (P → B) arrive valve piece B mouth again to equilibrium valve 8 to arrive auxilliary oil cylinder cavity of resorption again; Promptly the connect fluid of cylinder intermediate cavity of small oil tank epicoele is discharged to fuel tank to main valve piece T mouth through little valve piece C mouth to second ball valve 7 more again; Thereby make master cylinder motionless, small oil tank is up.
The angle of shear reduces: the Y5 of the Y1 of first solenoid directional control valve 3 end and second ball valve 6 holds; The pressure oil that oil pump is got arrives auxilliary oil cylinder epicoele (between the series connection cylinder) through second ball valve 6; Master cylinder is motionless; Auxilliary oil cylinder is descending, and (the T mouth that B → T) arrives the valve piece again is oil sump tank again to second solenoid directional control valve 4 again through equilibrium valve 8 through the B mouth of valve piece for the oil of auxilliary oil cylinder cavity of resorption.
The utility model adopts threaded cartridge valve just, makes the valve of not being with valve body be arranged in the hole of valve piece, through the inner passage in the valve piece with communicating with each other between these valves; Promptly reach the control effect, design will significantly reduce the volume of valve body and the debugging difficulty of whole valve body like this, and because this patent is a threaded cartridge valve; Therefore communicate with each other through the inner passage; So be difficult for oil leakage phenomenon takes place, thus the Security that has improved whole hydraulic valve bank greatly, and whole project organization is simple; Be easy to install, therefore be easy to produce in enormous quantities.
The above; It only is the preferred embodiment of the utility model; Be not to be the utility model to be done the restriction of any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that the technical spirit of the utility model is done.
