Description

Hydraulic press with impact apparatus for correcting
Technical field
The present invention relates to hydraulic press technical fields, more particularly to the hydraulic press with impact apparatus for correcting.
Background technique
Hydraulic press is a kind of machinery that the products such as metal, plastics, rubber, timber, powder are processed using hydrostatic pressure.
It is usually used in pressing process and block pressing forming process, such as: forging and stamping, punching press, cold-extruded, alignment, bending, flange, thin plate Drawing, powder metallurgy, press fitting etc..Existing hydraulic press has four-column type, horizontal, vertical frame and multilayer by structure type point The forms such as steel strip winding frame.Wherein: medium and small vertical hydraulic press is often used open side type, also referred to as c-type posture, open side type liquid Three face of press 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 fixed height, causes inconvenient, is unfavorable for It adjusts.And hydraulic cylinder is also required to refuel in time, and the placement of the oil pump of oiling, oil pipe is more random, inconvenient for operation, and It is easy to appear confusion, it is relatively inefficient.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, directly overflow oil pressure diversion reverse is rushed the present invention provides a kind of The elevation device for hitting device opens reverse impact elevation device, then PLC control device according to three-phase flow spill valve work State opens recoil hydraulic cylinder, and then starts to recoil, and prevents the excessive damage punching press components of stamping device pressure.
The technical scheme adopted by the invention is that: have impact apparatus for correcting hydraulic press, including pedestal, four-post frame frame, Stamping device, hydraulic cylinder and PLC control device, stamping device are connected to the top position punching press up and down of four-post frame frame;It is hydraulic 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 top position of pedestal by elevation device, and threeway flow spill valve other end connects The elevation device of impact apparatus for correcting is connect, and then is opened or locking soft impulse circle, and the hydraulic cylinder that recoils is by very heavy Roof construction is supported on base bottom;Stamping device, hydraulic cylinder and recoil hydraulic cylinder are all connected with PLC control device and obtain driving Either stopping or pause instruction.
Further, soft impulse circle is wrapped on the pedestal of stamping device face, and soft impulse circle runs through pedestal On anti-stamped recess, anti-stamped recess along base top punching parts areas outside arrange.
Further, soft impulse circle is connected to the bottom position of pedestal by least three compressed springs, and then is soft Property impact circle with stamping device certain buffering strength is provided, guarantee its service life with higher.
Further, soft impulse circle is annulus shape structure, if passing through between bottom and elevation device top position Dry telescopic column connection, and buffer spring is cased with outside the telescopic column.
Further, PLC control device is fixed by the bracket the lateral location in pedestal.
Compared with prior art, the beneficial effects of the present invention are: the hydraulic press with impact apparatus for correcting of the invention, is 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 cylinder, and then start to recoil, prevents stamping device pressure according to the working condition of three-phase flow spill valve The excessive damage punching press components of power.
For synthesis, hydraulic press of the invention is provided with soft impulse circle above pedestal, which passes through punching The recoil hydraulic cylinder and jack structure of apparatus for correcting are hit, soft impulse circle is jacked up, is realized excessive to stamping device stamping press Alleviation.
That is, hydraulic press of the invention has overflow recoil decompression, guarantee the quality of punching press components, simultaneously It prevents hydraulic cylinder from pressing long-term power excessive and burning out, improves the service life of hydraulic cylinder.
Detailed description of the invention
Fig. 1 is the structure chart of one embodiment of the hydraulic press with impact apparatus for correcting;
Wherein: 1- pedestal, the anti-stamped recess of 101-;2- four-post frame frame, 3- stamping device, 4- hydraulic cylinder, 5- threeway are overflow Stream valve, 6- fueller, 7- impact apparatus for correcting, 71- soft impulse circle, 72- elevation device, 73- recoil hydraulic cylinder, 74- telescopic column, 75- buffer spring, 76- jack structure;8- compressed spring, 9-PLC control device, 10- bracket.
Specific embodiment
In order to deepen the understanding of the present invention, present invention will be further explained below with reference to the attached drawings and examples, the implementation Example for explaining only the invention, does not constitute protection scope of the present invention and limits.
As shown in Figure 1, have the hydraulic press of impact apparatus for correcting, including it is pedestal 1, four-post frame frame 2, stamping device 3, hydraulic Oil cylinder 4 and PLC control device 9, stamping device 3 are connected to the top position punching press up and down of four-post frame frame 2;Hydraulic cylinder 4 passes through One threeway flow spill valve 5 connects fueller 6;Impact apparatus for correcting 7, including soft impulse circle 71, elevation device 72 and anti- Fliud flushing compressing cylinder 73;Soft impulse circle 71 is fixed on the top position of pedestal 1 by elevation device 72, and threeway flow spill valve 5 is another The elevation device 72 of outer one end connection impact apparatus for correcting 7, and then opening or locking soft impulse circle 71, and it is hydraulic to recoil Oil cylinder 73 is supported on 1 bottom of pedestal by jack structure 76;Stamping device 3, hydraulic cylinder 4 and recoil hydraulic cylinder 73 connect It connects PLC control device 9 and obtains driving or stopping or pause instruction.
