High-pressure oil pipe 4, its oil return opening are connected to oil return line；Inserted valve 6, its oil inlet are connected to low pressure pipe 5, the connection of its oil outlet
In the oil inlet of O-shaped three position four-way directional control valve 12；Two solenoid directional control valves II 8, it is parallel to inserted valve 6, two electromagnetic switch
During II 8 dead electricity of valve, inserted valve 6 is not turned on, and after two solenoid directional control valves II 8 obtain electric transposition, inserted valve 6 turns on；And two
Solenoid directional control valve III 11, its oil inlet are connected to the oil outlet of inserted valve 6, its oil return opening is connected to oil return line 3, and one goes out
Hydraulic fluid port is connected to the left chamber of shearing oil cylinder 10, its another oil outlet is connected to the right chamber of shearing oil cylinder 10.
When punching oil cylinder 9 acts, during the piston rod left lateral of punching oil cylinder 9, two solenoid directional control valves II 8 it is electric, O-shaped three
12 left position of position and four-way reversing valve obtain it is electric, 5 pressure oil of low pressure pipe by inserted valve 6, O-shaped three position four-way directional control valve 12 left position into
Enter 9 right chamber of punching oil cylinder, 9 piston rod left lateral of punching oil cylinder.At this time low pressure oil simultaneously also by two solenoid directional control valves III 11 into
Enter to shear the left chamber of oil cylinder 10, keep shearing 10 piston rod of oil cylinder all the time upper.
When 9 piston rod of punching oil cylinder stops, two II 8 dead electricity of solenoid directional control valve, O-shaped 12 left position of three position four-way directional control valve
Dead electricity, 5 pressure oil of low pressure pipe are populated valve 6 and are enclosed in left, and low pressure pipe 5 is no longer to two solenoid directional control valves II 8, O-shaped
12 fuel feeding of three position four-way directional control valve, after even wearing micro- leakage because of inserted valve 6, seldom pressure oil can pass through two electricity
The direct oil return box of restriction of magnetic reversal valve II 8, will not make two solenoid directional control valves II 8, O-shaped three position four-way directional control valve 12
Into the influence of pressure oil leakage, so as to keep in situ for a long time.
When 9 piston rod right lateral of punching oil cylinder, solenoid directional control valve II 8 must be electric, and O-shaped 12 right position of three position four-way directional control valve obtains
Electricity, 5 pressure oil of low pressure pipe enter 9 left chamber of punching oil cylinder by the left position of inserted valve 6, O-shaped three position four-way directional control valve 12, at the same time
High-pressure oil pipe 4 enters 9 left chamber of punching oil cylinder, the piston rod right lateral of punching oil cylinder 9 by two solenoid directional control valves I 2.It is low at this time
Pressure oil enters the left chamber of shearing oil cylinder 10 simultaneously also by two solenoid directional control valves III 11 of solenoid directional control valve, keeps shearing oil cylinder
10 piston rods are all the time upper.
When shearing oil cylinder 10 acts, when shearing the piston rod left lateral of oil cylinder 10, two solenoid directional control valves II 8 obtain electric, low pressure
5 pressure oil of oil pipe enters shearing 9 right chamber of oil cylinder by the left position of 6, two solenoid directional control valves III 11 of inserted valve, shears oil cylinder 10
Piston rod left lateral.Low pressure oil also passes through the pressure oil port of O-shaped three position four-way directional control valve 12 at the same time at this time, since shear action is short
Temporarily and frequency is seldom, and the pressure oil of process influences to ignore on O-shaped three position four-way directional control valve 12, even if there is micro- leakage can also
Leaked away by high-pressure oil pipe 4, so as to keep punching oil cylinder position not moved because shear pressure changes.
When shearing the stopping of 10 piston rod of oil cylinder, two II 8 dead electricity of solenoid directional control valve, 5 pressure oil of low pressure pipe is populated
Valve 6 is enclosed in left, and low pressure pipe 5 no longer gives two III 11 fuel feeding of solenoid directional control valve, and 10 piston rod of shearing oil cylinder stops moving
Dynamic, after even wearing micro- leakage because of inserted valve 6, seldom pressure oil can pass through the throttling of two solenoid directional control valves II 8
The direct oil return box of mouth, cuts 10 piston rod of oil cylinder by compression shear due to oil return and will not glide because of dead weight, so as to keep for a long time
It is in situ.10 piston rod of shearing oil cylinder stop to be used for mold exchange and adjustment accuracy during middle position, and punching oil cylinder does not act at this time,
As long as the action shearing oil cylinder 10 of punching oil cylinder 9 is to revert to upper.
When shearing 10 piston rod right lateral of oil cylinder, two solenoid directional control valves III 11, two of solenoid directional control valve II 8, two
Solenoid directional control valve I 2 must be electric, and 5 pressure oil of low pressure pipe enters punching by the right position of 6, two solenoid directional control valves III 11 of inserted valve
9 left chamber of hole oil cylinder, while high-pressure oil pipe 4 enters shearing 10 left chamber of oil cylinder by two I 2 right positions of solenoid directional control valve, shears oil cylinder
10 piston rod right laterals.Low pressure oil also passes through the pressure oil port of O-shaped three position four-way directional control valve 12 at the same time at this time, since shear action is short
Temporarily and frequency is seldom, and the pressure oil of process influences to ignore on O-shaped three position four-way directional control valve 12, even if there is micro- leakage can also
Leaked away by two solenoid directional control valves I 2, so as to keep punching oil cylinder position not moved because shear pressure changes.
Further, the accumulator 7 for being arranged at 6 front end of inserted valve and being connected with low pressure pipe 5 is further included.Pass through accumulator
7 accumulation of energy, can improve the stability of low pressure oil way.Two I 2 oil return openings of solenoid directional control valve can also be included being arranged at returning
Fluid is set unidirectionally to flow to the return check valve 1 of oil return line 3 from oil return opening between oil pipe line 3.Return check valve 1 can anti-non-return
Fluid reflux in oil pipe line 3, further increases reliability.
