Abstract
The utility model relates to a protection system device without a magnetic field or with a weak magnetic field for pressing permanent ferrite tile-shaped magnet steel. The utility model is characterized in that a dry reed tube and a PLC controller are arranged at the exterior of a magnetizing coil of a semi-automatic molding press for processing and molding permanent ferrite tile-shaped magnet steel. When an oriented magnetic field of the device becomes weak or disappears, the protection system device is capable of automatically stopping, thereby avoiding the permanent ferrite tile-shaped magnet steel not oriented or not fully oriented entering into qualified end products.
Description
Technical field
The utility model relates to a kind of no magnetic field or low-intensity magnetic field protection system device of suppressing the permanent-magnet ferrite tile-shaped magnet steel.
Background technology
Anisotropy permanent-magnet ferrite product need to carry out, otherwise product is the isotropism product that its magnetic property is very low under alignment magnetic field when compression moulding, the client can not use.Permanent-magnet ferrite formed product press in the prior art is semi-automatic moulding press, and this semi-automatic moulding press is when product compression moulding, and whether existence can't detect its alignment magnetic field normal.When alignment magnetic field occurs when unusual, the product of compacting is isotropic or the waste product of orientation fully not.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is to be permanent-magnet ferrite formed product press, and a kind of no magnetic field or low-intensity magnetic field protection system device of suppressing the permanent-magnet ferrite tile-shaped magnet steel is provided.
The no magnetic field or the summary of low-intensity magnetic field protection system device context of the utility model compacting permanent-magnet ferrite tile-shaped magnet steel:
The no magnetic field or the low-intensity magnetic field protection system device of the utility model compacting permanent-magnet ferrite tile-shaped magnet steel is characterized in that: be outer setting tongue tube and the PLC controller at the coil that magnetizes of the semi-automatic moulding press of processing the moulding of permanent-magnet ferrite tile-shaped magnet steel.
The no magnetic field or the low-intensity magnetic field protection system device of the utility model compacting permanent-magnet ferrite tile-shaped magnet steel; when the alignment magnetic field of equipment weakens or does not have autostop sometimes, avoided non-oriented or not fully the permanent-magnet ferrite tile-shaped magnet steel product of orientation infiltrate in the qualified product.
Description of drawings
Fig. 1 is the no magnetic field or the low-intensity magnetic field protection system apparatus structure schematic diagram of compacting permanent-magnet ferrite tile-shaped magnet steel
Among the figure: the 1st, the coil that magnetizes, the 2nd, tongue tube, the 3rd, PLC controller.
Embodiment
The no magnetic field of the utility model compacting permanent-magnet ferrite tile-shaped magnet steel or low-intensity magnetic field protection system device are achieved in that to do below in conjunction with accompanying drawing and specify.See Fig. 1; the no magnetic field or the low-intensity magnetic field protection system device of the utility model compacting permanent-magnet ferrite tile-shaped magnet steel; be outer setting tongue tube 2 and PLC controller 3 at the coil 1 that magnetizes of the semi-automatic moulding press of processing the moulding of permanent-magnet ferrite tile-shaped magnet steel; tongue tube 2 is as the magnetic field detection element; by the PLC control program of PLC controller 3 programming apparatus, achieve no magnetic defencive function.
When equipment operation to the coil 1 of magnetizing when electric, the coil 1 that magnetizes electric, set up magnetic field, 2 work of magnetic field detection signal tongue tube feed back to PLC controller 3, PLC controller 3 output orders, equipment normally moves.PLC controller 3 output halt instructions when the alignment magnetic field of equipment weakens or do not have, equipment downtime is also reported to the police, autostop, thus realize the protection of no magnetic.
Claims (1)
1. a no magnetic field or a low-intensity magnetic field protection system device of suppressing the permanent-magnet ferrite tile-shaped magnet steel is characterized in that: be outer setting tongue tube (2) and the PLC controller (3) at the coil that magnetizes (1) of the semi-automatic moulding press of processing the moulding of permanent-magnet ferrite tile-shaped magnet steel.
