Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, metal shearing machine hydraulic control valve group described in the utility model by organizing two-way plug-in valve more, solenoid directional control valve, sequence valve form, the B chamber of filler opening 1 and the first two-way cartridge insertion direction valve 8, the P chamber of the second solenoid directional control valve 6, the B chamber of the second two-way cartridge insertion direction valve 12 are connected with the P chamber of the 3rd solenoid directional control valve 11, and return opening 2 is connected with the B chamber of two-way plug-in mounting fuel outlet valve 9 and sequence valve 13 return opening with the B chamber of two-way plug-in mounting pressure valve 3.The plug chamber of binder cylinder 16 is connected with the A chamber of the second solenoid directional control valve 6, and the bar chamber of binder cylinder 16 is connected with the B chamber of the second solenoid directional control valve 6.The plug chamber of shear cylinder 15 is connected with the A chamber of two-way plug-in mounting fuel outlet valve 9 with the A chamber of the first two-way cartridge insertion direction valve 8, and the bar chamber of shear cylinder 15 is connected with the A chamber of sequence valve 13 with the A chamber of the second two-way cartridge insertion direction valve 12.Relief valve function cover plate 4 has the function controlling whole valve group pressure, and the first solenoid directional control valve 5 has the C chamber of control two-way plug-in mounting pressure valve 3 and the on-off function of oil return.
This valve group actuation cycle is as follows: under each solenoid valve off-position, and the C chamber of two-way plug-in mounting pressure valve 3 is connected with oil return, and two-way plug-in mounting pressure valve 3 is opened completely, and pump discharge hydraulic oil flows back to fuel tank, and system is without pressure, and whole system is in drain charge state.When the first solenoid directional control valve 5 is energized, the C chamber of two-way plug-in mounting pressure valve 3 and oil return disconnect, and system sets up pressure, by the adjustment pressure of relief valve function cover plate 4, simultaneously the B of the second solenoid directional control valve 6 holds electromagnet energising to switch to PA to lead to spool, and BT leads to, and pressure oil enters binder cylinder 16 and fills in chamber, and binder cylinder 16 advances workpiece pressing, 3rd solenoid directional control valve 11 is energized immediately, PB is switched to lead to spool, AT leads to, pressure oil is by the 3rd solenoid directional control valve 11, control cover plate 14, control cover plate 10, second two-way cartridge insertion direction valve 12 and two-way plug-in mounting fuel outlet valve 9 are in closed condition, the first two-way cartridge insertion direction valve 8 is made to be in opening state, pressure oil enters shear cylinder 15 and fills in chamber, shear cylinder 15 advances, now the pressure oil in shear cylinder 15 bar chamber overcomes the second two-way cartridge insertion direction valve 12 opening force, second two-way cartridge insertion direction valve 12 is opened, bar chamber oil subsidy is in main system, increase the oil inlet quantity in plug chamber, form hydraulic differential, shear cylinder 15 advances fast.After shear cylinder 15 contacts workpiece, system pressure increases to over sequence valve setting pressure, and now sequence valve 13 is opened, and shear cylinder 15 bar chamber oil flows back to fuel tank, forms work and enters shear action.
Shear action ends, 3rd solenoid directional control valve 11 power-off, 3rd solenoid directional control valve 11 spool resets under spring force, spool PA leads to, and BT leads to, and the second two-way cartridge insertion direction valve 12 and two-way plug-in mounting fuel outlet valve 9 are opened, pressure oil enters shear cylinder 15 bar chamber, shear cylinder 15 fills in chamber oil oil sump tank simultaneously, and shear cylinder 15 retreats, and forms backhaul action; The A of the second solenoid directional control valve 6 holds electromagnet energising simultaneously, and spool PB leads to, and AT leads to, and binder cylinder 16 completes the backhaul action of hold-down cylinder.
More than describing is to explanation of the present utility model, and be not the restriction to model utility, when without prejudice to the utility model spirit, the utility model can do any type of amendment.
