Description
Technical field
The invention belongs to mechanical field, and in particular to a kind of new minute-pressure system.
Background technology
At present, the hydraulic system used in most of heat pressing forming machines, there is hydraulic pump, pressure regulator valve, pressurize check valve, pressure gauge
Constituted with hydraulic cylinder etc., there is unreasonable structure, slight pressure locked mode can not be realized, 1% pressure control once of such as nominal pressure
System, does not meet actual use technological requirement.
The content of the invention
Goal of the invention：The invention aims to overcome deficiency of the prior art, there is provided a kind of rational in infrastructure, pressure
Control accuracy is high, slight pressure locked mode can be realized, such as 0.1% Stress control once of nominal pressure, it is possible to realize bent
A kind of new new minute-pressure system of line pressure control.
Technical scheme：In order to solve the above-mentioned technical problem, a kind of new minute-pressure system of the present invention, including：Perform
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, servomotor one, servomotor two, servo controller one, servo controller two, data wire one, data wire
Two and host computer；The control valve one and control valve two control the action of actuator one and actuator two respectively, and control valve one,
Control valve two makees pressure protection respectively by safety valve one, safety valve two respectively；The servo controller one, servomotor one, oil
Pump one, pressure sensor one are sequentially connected, and servo controller two, servomotor two, oil pump two, pressure sensor two connect successively
Connect；Pressure requirements and real-time pressure that the servo controller one, servo controller two are set according to host computer, by servomotor
First, oil pump one, the output hydraulic pressure flow of oil pump two and the pressure that servomotor two is connected 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 formed respectively
Bis- closed loops of minute-pressure A and pressurize 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 wire one, data wire two
It is connected with the host computer, and forms communication.
Further, actual pressure value reads host computer, and is stored in the database of host computer, the pressure in database
Data can be inquired about and output formats, curve, it is possible to achieve the automatically controlling of slight pressure and normal pressure, pressure oscillation are small.
Further, when required pressure is in minute-pressure scope, host computer（Industrial computer）Pressure set points are communicated and watched to A rings
Controller 1 is taken, when required pressure exceedes minute-pressure scope, host computer（Industrial computer）Pressure set points are communicated and give B ring servos
Controller two, is realized to the Stress controls of heat pressing forming machines, and minimum pressure can control the 0.1% of nominal pressure once.
Beneficial effect：Compared with prior art, its remarkable advantage is the present invention：Global design of the present invention is reasonable, pressure control
