Description
Technical field
The invention belongs to technical field of hydraulic, and in particular to a kind of dynamic beam speed governing oil circuit for being mainly used in hydraulic press
Structure.
Background technology
As shown in figure 1, a kind of dynamic beam speed governing oil channel structures of existing hydraulic press are mainly by delivery valve 1, draining valve
2nd, moving beam quickly controls oil circuit 3 and dynamic beam to control oil circuit 4 to form at a slow speed, to drive the hydraulic actuating mechanism 5 of hydraulic press
Action, its structure are：Delivery valve 1 is connected with pressure oil-source 6；Draining valve 2 is connected with the fuel tank 51 of hydraulic actuating mechanism；Dynamic beam is fast
Speed control oil circuit 3 is connected with the cylinder rod chamber 53 of delivery valve, draining valve and hydraulic actuating mechanism respectively；Dynamic beam controls at a slow speed oil
Road 4 is connected with the cylinder rod chamber 53 of delivery valve, draining valve and hydraulic actuating mechanism respectively.Wherein, move beam and quickly control oil circuit 3
Inserted valve 31 is quickly moved by a dynamic beam to form, dynamic beam controls at a slow speed oil circuit 4 by dynamic beam descending at slow speed inserted valve 41 and dynamic beam
Rise inserted valve 42 at a slow speed to form.Moreover, it is electromagnetic pilot-operated that delivery valve 1, draining valve 2, dynamic beam, which quickly move inserted valve 31,
Inserted valve, and it is common inserted valve that dynamic beam descending at slow speed inserted valve 41 and dynamic beam, which rise at a slow speed inserted valve 42, on off state is not
By On-line Control.The operation principle of this kind of dynamic beam speed governing oil channel structures is：The dynamic beam 55 of hydraulic actuating mechanism is by cylinder piston rod
54 drivings, its ascending motion are the control by controlling fuel delivery to carry out speed.When dynamic beam 55 rises, the delivery valve 1 in oil circuit
Unlatching, draining valve 2 are closed, and the pressure oil of pressure oil-source 6 enters in oil circuit.When dynamic beam 55 needs to make rapid increase action, move
Beam quickly moves inserted valve 31 and dynamic beam controls at a slow speed the dynamic beam in oil circuit to rise inserted valve 42 at a slow speed while opened, then pressure oil
Quickly control oil circuit and dynamic beam to control a large amount of cylinder rod chambers 53 for entering hydraulic actuating mechanism at a slow speed through moving beam, make oil cylinder piston
The rapid increase of bar 54 drives the dynamic rapid increase of beam 55.When dynamic beam 55 needs to make vertical motion at a slow speed, then close dynamic beam and quickly transport
Move inserted valve 31 and open dynamic beam and rise inserted valve 42 at a slow speed, then pressure oil controls oil circuit to have on a small quantity into oil cylinder at a slow speed through dynamic beam
Rod cavity 53, cylinder piston rod is risen the dynamic beam of drive at a slow speed and rise at a slow speed.Equally, the descending motion for moving beam is by controlling oil extraction
Amount carries out the control of speed.When dynamic beam declines, the draining valve in oil circuit is opened and delivery valve is closed, the pressure in cylinder rod chamber 53
Power oil enters the fuel tank 51 of hydraulic actuating mechanism through draining valve.When dynamic beam needs to make rapid decrease action, dynamic beam quickly moves
Inserted valve 31 and dynamic beam control at a slow speed the dynamic beam descending at slow speed inserted valve 41 in oil circuit while opened, then oil when moving beam rapid decrease
The pressure oil that cylinder rod chamber 53 is largely discharged quickly controls oil circuit and dynamic beam to control oil circuit to discharge at a slow speed through dynamic beam；When dynamic beam needs
When making descending at slow speed action, close dynamic beam and quickly move inserted valve 31 and open dynamic beam descending at slow speed inserted valve 41, then it is slow to move beam
The pressure oil that cylinder rod chamber is discharged on a small quantity when speed declines controls oil circuit to discharge at a slow speed through dynamic beam.Due to such a control oil channel structures
Dynamic the beam rate of climb and decrease speed respectively there are two common inserted valves to be controlled, i.e., can only at most realize two-stage adjust
Speed, if the motion of dynamic beam, due to the unexpected transformation of speed, is easily held from when quickly motion is changed into microinching to whole hydraulic pressure
Row mechanism impacts.
In addition, the dynamic beam speed governing oil channel structures for also having a kind of hydraulic press are to use a two-position three way plug-in ratio
Servo valve and the inserted valve of on-off action realize the servo-controlled of dynamic beam.The use of proportional servo valve, although can realize
The step-less adjustment of speed, make beam motion more accurate soft.But because proportional servo valve arrangement is more accurate, and easily go out
Existing failure, and need to configure the electric control system of higher performance, production and maintenance cost will necessarily so be significantly increased.
