Description
Technical field
The invention belongs to machinery fields, and in particular to a kind of novel minute-pressure system.
Background technique
Currently, hydraulic system used in most of heat pressing forming machines, there is hydraulic pump, pressure regulator valve, pressure maintaining check valve, pressure gauge
It is formed with hydraulic cylinder etc., there are unreasonable structure, can not achieve slight pressure mode locking, such as 1% pressure control once of nominal pressure
System does not meet actual use technique requirement.
Summary of the invention
Goal of the invention: purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of structurally reasonable, pressure
Control precision is high, slight pressure mode locking may be implemented, and as 0.1% pressure once of nominal pressure controls, and song may be implemented
A kind of novel novel minute-pressure system of line pressure control.
Technical solution: in order to solve the above-mentioned technical problem, a kind of novel minute-pressure system of the present invention, comprising: execute
Device one, actuator two, control valve one, control valve two, safety valve one, safety valve two, pressure sensor one, pressure sensor two,
Oil pump one, oil pump two, servo motor one, servo motor two, servo controller one, servo controller two, data line one, data line
Two and host computer；The control valve one and control valve two control the movement of actuator one and actuator two respectively, and control valve one,
Control valve two makees pressure protection by safety valve one, safety valve two respectively respectively；The servo controller one, servo motor one, oil
Pump one, pressure sensor one are sequentially connected, and servo controller two, servo motor two, oil pump two, pressure sensor two successively connect
It connects；The pressure requirements and real-time pressure that the servo controller one, servo controller two are set according to host computer, by servo motor
One, oil pump one, two output hydraulic pressure flow of oil pump and the pressure that servo motor two connects are to actuator one, actuator two；The pressure
Real-time pressure signal is fed back to servo controller one, servo controller two by force snesor one, pressure sensor two, is respectively formed
Bis- closed loops of minute-pressure A and pressure maintaining B；The pressure sensor one, pressure sensor two feed back to real-time pressure signal respectively to be watched
Take controller one, servo controller two；The servo controller one, servo controller two are respectively by data line one, data line two
