Background technology
At present, known solution Nd-Fe-B permanent magnet material forming process occurring, the device without magnetic is the electric magnet at moulding press
Near-end installs a relay, and the two ends of relay are respectively connected to programmable logic controller (PLC) signal and an effective input
Son, in orientation process, when electric magnet no current passes through, the not adhesive because of non-inductive magnetic field of the normally opened contact within relay,
Programmable logic signal disconnects, and cuts off oil cylinder and presses down the relay power of function, stops die mould.This device solve only
Without the problem that equipment under magnetic state is out of service, but when the internal turn-to-turn short circuit of electric magnet, electric current is become by the number of turn of electric magnet
Few big electric current downfield caused, causes orientation insufficient, easily occurs because orientation field intensity causes the phenomenon of the weak magnetic of product not.
Summary of the invention
When present invention seek to address that the internal turn-to-turn short circuit of electric magnet in forming process, electric current is tailed off by the number of turn of electric magnet and draws
The big electric current downfield risen, causes orientation insufficient, easily occurs that orientation field intensity causes this technical barrier of weak magnetic phenomenon not,
By detecting electric current, magnetic field and instruction alarm lamp simultaneously, thus realize detecting signal under weak magnetic state, make equipment stop fortune
The Advantageous Effects of row.
For achieving the above object, the present invention provides a kind of moulding press triple UNPROFOR device, including:
For detecting the amperometric of electromagnet current;
In order to detect the magnetic sensors of the magnetic field intensity of mould cavity;
One programmable logic controller (PLC) is connected with described amperometric and magnetic sensors, and receives and send based on both
Signal thus activate or stop moulding press operation;
One alarming device is connected with described programmable logic controller (PLC).
Wherein, described magnetic sensors is positioned at moulding press electric magnet near-end.
Wherein, there is a magnetic field induction switch in described magnetic sensors, controlled to FPGA by this inductive switch Guan Bi
The signal output of controller.
Wherein, described alarming device is instruction warning light or instruction alarm bell.
Wherein, described alarming device is connected with described programmable logic controller (PLC) by an instruction alarm relay.
The present invention also provides for a kind of moulding press triple UNPROFOR method, and it comprises the technical steps that:
Electromagnet current during amperometric detection orientation, by the current output signal input programmable logic controller (PLC) of detection;
The magnetic field intensity of magnetic sensors detection mould cavity, by the magnetic field intensity signal input programmable logic controller (PLC) of detection;
Described programmable logic controller (PLC) receives magnetic field induction switch and the output signal of amperometric simultaneously, when the electricity of detection
Intensity of flow and magnetic field intensity any one when not reaching preset value, activate alarming device.
Wherein, described current intensity preset value is 60-100A.
Wherein, described magnetic field intensity preset value is 10000-20000GS.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of moulding press of the present invention triple UNPROFOR device
Wherein 1. oil cylinder, 2. instruction alarm lamp, 3. magnetic sensors, 4. electric magnet, 5. electrical control cubicles, 6. amperometric,
7. programmable logic controller (PLC), 8. oil cylinder relay, 9. instruction alarm relay, 10. Hydraulic Station, 11. mould cavities.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described in detail, it is to be understood that this utility model
Protection domain do not limited by detailed description of the invention.
As it can be seen, apparatus of the present invention include electrical control cubicles (5), mould cavity part (11) and Hydraulic Station (10), electricity
Control cabinet is provided with amperometric (6), its outfan and the programmable logic controller (PLC) (7) being located in electrical control cubicles
End is connected;This programmable logic controller (PLC) (7) one end is connected with a Hydraulic Station (10) by an oil cylinder relay (8);
Mould cavity (11) includes electric magnet (4), and magnetic sensors (3) passes through can in internal magnetic field inductive switch and electrical control cubicles
Programmed logic controller (7) is connected, and instruction alarm lamp (2) is by indicating alarm relay (9) with able to programme
Logic controller (7) is connected, and is furthermore provided with an oil cylinder (1).
Working as system short-circuit, electric current is tailed off by the number of turn of electric magnet the big electric current downfield caused, and causes orientation insufficient, goes out
Now orientation field intensity causes weak magnetic phenomenon not, and in electric magnet (4) orientation process now, described amperometric (6) is opened
Begin detection output electric current, if output electric current is less than test value 60-100A, inside the relay on this amperometric (6)
Normally opened contact not adhesive, the signal of the programmable logic controller (PLC) (7) being connected with its one end disconnects, thus will with can compile
Oil cylinder relay (8) dump that the journey logic controller other end is connected, oil cylinder (1) stopping action;
In electric magnet (4) orientation process, magnetic sensors (3) induced field, if magnetic field intensity is less than 10000-20000GS
Time (this magnetic field intensity, both can guarantee that the orientation that product has had, and can prevent again being orientated electric current and cause greatly electric magnet to generate heat, line
Enclose aging, the lost of life).It is arranged on the relay normally open contact of the internal magnetic field induction switch internal of magnetic sensors (3)
Not adhesive, programmable logic controller (PLC) (7) no signal being connected with its one end exports, thus will be with Programmable logical controller
Oil cylinder relay (8) dump that the device other end is connected, oil cylinder (1) stopping action;
In electric magnet (4) orientation process, described amperometric (6) or with any one in magnetic sensors (3)
Device does not reaches preset value, and the instruction being connected with the rwo programmable logic controller (PLC) (7) outfan being connected all can be made alert
Telegraph relay (9) dump, the instruction alarm lamp (2) being arranged on operative employee front does not works, and operative employee can find immediately
Abnormal, stop die mould.
Therefore, this moulding press triple UNPROFOR method and device is by whole to amperometric, magnetic sensors, instruction alarm lamp
Enroll in program, play the effect of triple UNPROFORs, can keep away by detecting electric current, magnetic field and instruction warning light simultaneously
Exempt to occur without magnetic, weak magnetic phenomenon, three any one exception detected, press can be stopped running.Thus thoroughly stop nothing
Orientation compacting, the generation of weak magnetic pressure.
The specific embodiment being only the present invention disclosed above, but, the present invention is not limited to this, any this area
Technical staff can think change all should fall into protection scope of the present invention.
