Description
Technical field
The present invention relates to mechanical press, and in particular to mechanical press atmospheric control belongs to mechanical press skill
Art field.
Background technology
It is well-known：It is by changing clutch brake that the job specification of forcing press, which is clutch brake control device,
The state of device and the movement and stopping for realizing forcing press.When press motion, control device makes brake air inlet, air pressure push open
Spring is detached from braking, clutch air inlet simultaneously, and air pressure pressing friction block realizes that clutch engagement, clutch drive transmission system fortune
Turn；When forcing press stops, clutch is died disengagements, and brake is died simultaneously, and spring compression brake apparatus is braked to realize.
This working characteristics, it is desirable that must have reliable coordination between Clutch and brake, i.e.,：Work as start-up operation
When, disengaging for brake will be slightly in advance in the combination of clutch, i.e.,：Drive brake disengage power air pressure will slightly in advance in
The operating air pressure for driving clutch to combine, can not occur the interference between Clutch and brake, or thereby result in this way
Mechanical press can not work normally the phenomenon that setting damage mechanical press, and when mechanical press is stopped, it is desirable that
Clutch first disengages, and brake is braked later, i.e.,：Compressed air in clutch cylinder will quickly be discharged, so as in clutch
Resetting spring by clutch Quick release, and in brake at this time compressed air discharge slightly to delay in the pressure in clutch
Contracting air, rhythm are：After compressed air discharge in clutch, clutch separation, then compressed air in brake is
It excludes, brake starts to brake completely.
Pneumatic control system of pressing machine must have good it can be seen from the course of work of Pneumatic control system of pressing machine
Rhythm controls the harmonious work of Clutch and brake, can ensure that Clutch and brake does not occur for forcing press
Between interference, or thereby result in mechanical press can not work normally setting damage mechanical press the phenomenon that, and currently,
Since the time of this interference is extremely short, and will not occur larger problem in the short time, so more or less by some
Pressure produces institute or omits, although also disclosing that the technology for solving press machine clutch and brake interference in existing technology,
But more or less there is the hidden danger of secure context in these technologies, such as：Chinese invention patent number 200810139268.8, name
Referred to as《Press machine clutch brake control device》Disclosed technology, although the technology solve better clutch with
Brake interference problem, but a single valve is arranged in the technology on the air inlet pipeline of clutch cylinder,（Note：Specification and
Number in Figure of description is 17）, since the probability that solenoid valve breaks down is higher, under corresponding malfunction, electromagnetism
Valve will present pass-through state, and result at this time is exactly that compressed air enters clutch, and clutch, which combines, causes forcing press improper
Work, it is clear that this can lead to serious safety accident.
Invention content
The purpose of the present invention provides one aiming at the drawbacks described above present in existing machinery Pneumatic control system of pressing machine
Kind can effectively overcome the novel press machine atmospheric control of drawbacks described above.
Pneumatic control system of pressing machine of the present invention, it be by：Check valve, pressure regulator valve, gas receiver, safety valve, pressure
Power relay, filter, oil sprayer, duplex solenoid valve, two-bit triplet solenoid valve, stopper cylinder, auxiliary control gas circuit, clutch
Device cylinder, Pneumatic control type check valve, rotary air inlet connector, rapid escape valve, throttle valve, clutch air inlet pipeline are formed,
It is provided with safety valve and pressure switch on the gas receiver, is the prior art, gas receiver passes through pressure regulator valve and list successively
It is connected to valve with ambient pressure air-source, is the prior art, gas receiver is in the pipeline for leading to clutch cylinder and stopper cylinder
On be disposed with filter, oil sprayer and duplex solenoid valve, it is characterized in that：Duplex electromagnetism valve air gate also with two three
Three-way electromagnetic valve is connected, and it is directly identical as air that the straight-through pipeline of two-bit triplet solenoid valve passes through throttle valve on one side, in addition one side with
The cylinder interior of brake is connected, and draws one on the pipeline that two-bit triplet solenoid valve is connected with the cylinder interior of brake simultaneously
Auxiliary control gas circuit and clutch air inlet pipeline, clutch air inlet pipeline successively with Pneumatic control type check valve and rotating inlet
Connector enters after being connected in the cylinder of clutch, control terminal of the auxiliary control gas circuit directly with Pneumatic control type check valve
Mouth is connected, and the rotary air inlet connector is connected with rapid escape valve to be communicated with air.
The present invention operation principle be：Extraneous powered compressor air-source enters gas storage later via check valve, pressure regulator valve
In cylinder, check valve ensures extraneous bleed pressure when relatively low, and the gas in gas receiver will not reversely flow out, pressure regulator valve set into
Enter the maximum pressure in gas receiver, safety valve is the Machine guarding of system, prevents damage of the hypertonia to system, pressure
Relay is the electric protective device of system, electrical command is sent out if hypotony, halt system operating is the prior art.
Compressed air need to pass through filter and filter, and oil sprayer provides certain lubricating oil for pipeline, and lubricating oil passes through pipeline
Parts on pipeline are lubricated, in the case that duplex solenoid valve is powered simultaneously with two-bit triplet solenoid valve, then duplex is electric
Magnet valve is simultaneously turned on two-bit triplet solenoid valve, by the compressed air in gas receiver, by filter, oil sprayer, duplex electromagnetism
Valve, two-bit triplet solenoid valve enter the cylinder of brake, and brake is disengaged, meanwhile, auxiliary controls gas circuit by the compressed air
It is passed through the control port of Pneumatic control type check valve, Pneumatic control type check valve is opened, then the compression from gas receiver is empty
Gas via the cylinder of surprising clutch after Pneumatic control type check valve, rotary air inlet connector, clutch is combined, due to simultaneously again
Compressed air from gas receiver is to be directly entered in the cylinder of brake, and enter the cylinder of clutch then due to wanting air pressure
Conducting can just enter control formula check valve in advance, this existence time is poor, thus brake first disengages, and is combined after clutch,
It will not be interfered between Clutch and brake, in addition, Pneumatic control type check valve is due to being entirely mechanical structure, failure rate
The low compressed air of control to greatest extent accidentally enters clutch cylinder, ensures that the safety of forcing press is reliable, and works as duplex
In the case that solenoid valve powers off simultaneously with two-bit triplet solenoid valve, the cut-off of duplex solenoid valve, and two-bit triplet solenoid valve will be braked
The cylinder of device is directly communicated with air, and air in stopper cylinder is discharged, due to the effect of throttle valve, the discharge of this air by
To limitation, and the compressed air in clutch cylinder can then be discharged from rapid escape valve without restriction, realize clutch
The braking purpose prior to brake is detached, guarantee will not interfere between the two.
Advantageous effect：The energy of the present invention it can be seen from the introduction of the principle of the present invention schematic diagram and above-mentioned operation principle
The defect of mechanical press Clutch and brake interference is enough efficiently solved, while also having the advantages that security performance is higher.
