The face of press three is opened wide, operating aspect.But existing various hydraulic presses, especially single column hydraulic machine, it is provided only with a liquid
Cylinder pressure so that working ability is limited.And existing hydraulic press pillar is all level altitude, causes operation inconvenience, be unfavorable for
Regulation.And hydraulic jack is also required to timely oiling, and the oil pump, the oil pipe that refuel place more random, inconvenient operation, and
Easily cause confusion, it is relatively inefficient.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, directly overflow oil pressure diversion reverse is rushed the invention provides a kind of
Hit the elevation device of device, reverse impact elevation device opened, then PLC control devices according to three-phase flow spill valve work
State, opens recoil hydraulic jack, and then starts recoil, prevents decompressor pressure is excessive from damaging punching press parts.
The technical solution adopted in the present invention is：With impact apparatus for correcting hydraulic press, including base, four-post frame frame,
Decompressor, hydraulic jack and PLC control devices, decompressor are connected to punching press above and below the tip position of four-post frame frame；Hydraulic pressure
Oil cylinder connects fueller by a threeway flow spill valve；Impact apparatus for correcting, including soft impulse circle, elevation device and anti-
Fliud flushing compressing cylinder；Soft impulse circle is fixed on the tip position of base by elevation device, and threeway flow spill valve other end connects
Connect impact apparatus for correcting elevation device, and then open or locking soft impulse circle, and reversely hydraulic jack pass through it is very heavy
Roof construction is supported on base bottom；Decompressor, hydraulic jack and recoil hydraulic jack are all connected with PLC control devices and obtain driving
Or stop or pause instruction.
Further, soft impulse circle be wrapped in decompressor just to base on, and soft impulse circle run through base
On anti-stamped recess, anti-stamped recess along base top punching parts areas outside arrangement.
Further, soft impulse circle is connected to the bottom position of base by least three compression springs, and then is soft
Property impact circle provide certain buffering strength with decompressor, it is ensured that it has higher service life.
Further, soft impulse circle be toroidal structure, if between its bottom and elevation device tip position by
Dry telescopic column connection, and it is cased with buffer spring outside the telescopic column.
Further, PLC control devices are fixed on the lateral location of base by support.
Compared with prior art, the beneficial effects of the invention are as follows：The hydraulic press with impact apparatus for correcting of the present invention, be
A kind of to open reverse impact elevation device directly by the elevation device of overflow oil pressure diversion reverse percussion mechanism, then PLC is controlled
Device processed opens recoil hydraulic jack according to the working condition of three-phase flow spill valve, and then starts recoil, prevents decompressor pressure
Power is excessive to damage punching press parts.
For synthesis, hydraulic press of the invention is provided with soft impulse circle above base, and the soft impulse circle is rectified by impact
The recoil hydraulic jack and jack structure of equipment, jack-up soft impulse circle realize excessive to decompressor stamping press delay
Solution.
That is, the hydraulic press of the present invention has overflow recoil decompression, it is ensured that the quality of punching press parts, simultaneously
Prevent hydraulic jack from pressing long-term power excessive and burning out, improve the service life of hydraulic jack.
