Abstract
The utility model discloses a kind of moulding press without magnetic field protection arrangement; comprise press control circuit, hollow magnetizing coil and electromagnetic relay switch; described press control circuit is used for being controlled to the Kai Heguan of swaging machine, and described hollow magnetizing coil, electromagnetic relay switch and press control circuit are connected on power circuit successively.Hollow magnetizing coil, electromagnetic relay switch and original press control circuit are connected by the utility model, and when hollow magnetizing coil has magnetic field, hollow magnetizing coil attracts electromagnetic relay switch to close, and press control circuit is energized, and controls press and normally works; When hollow magnetizing coil is without magnetic field, electromagnetic relay switch disconnects, and press control circuit no power, moulding press does not work.Ensure when in hollow magnetizing coil without magnetic field time, press does not produce ferrimagnet, strictly the appearance of control substandard product.
Description
Technical field
The utility model relates to a kind of without magnetic field protection arrangement, particularly relates to a kind of moulding press without magnetic field protection arrangement.
Background technology
According to ferrite permanent magnet material forming process, for the wet pressing permanent-magnet ferrite formed product of a mould one, adopt the magnetization of single line bag shaping, the magnetic field in its forming cavity meets the demands substantially.But to one-mold multiple-member, its Bi along loop length L directional spreding uneven cannot meet and guarantee to obtain in each shaping mold cavity design height and uniform magnetizing field strength, thus the structure of hollow magnetization coil combination magnetic circuit must be adopted to change the inhomogeneities of Magnetic Induction Density Distribution, thus improve magnetic degree of orientation in magnetic field, improve permanent magnet residual magnetism Br, improve the performance of product.
But in prior art, the situation in magnetic field in hollow magnetizing coil can not be detected, when in hollow magnetizing coil without magnetic field time, moulding press produce ferrimagnet product in there is substandard product, cause the waste of production cost.Therefore, providing a kind of can the device of the hollow magnetization coil magnetic field of Real-Time Monitoring be those skilled in the art's good problems to study.
Utility model content
The purpose of this utility model is for deficiency of the prior art, providing magnetic field conditions in the hollow magnetizing coil of a kind of energy Real-Time Monitoring, automatically can be broken into the device of swaging machine when occurring without magnetic field conditions.
For Problems existing in above background technology; the technical solution adopted in the utility model is: a kind of moulding press is without magnetic field protection arrangement; comprise press control circuit, hollow magnetizing coil and electromagnetic relay switch; described press control circuit is used for being controlled to the Kai Heguan of swaging machine, and described hollow magnetizing coil, electromagnetic relay switch and press control circuit are connected on power circuit successively.
Further, described electromagnetic relay switch comprises armature, spring, moving contact and fixed contact.
Compared with prior art, the beneficial effect that the utility model has is: hollow magnetizing coil, electromagnetic relay switch and original press control circuit are connected by the utility model, when hollow magnetizing coil has magnetic field, hollow magnetizing coil attracts electromagnetic relay switch to close, press control circuit is energized, and controls press and normally works; When hollow magnetizing coil is without magnetic field, electromagnetic relay switch disconnects, and press control circuit no power, moulding press does not work.Ensure when in hollow magnetizing coil without magnetic field time, press does not produce ferrimagnet, strictly the appearance of control substandard product.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment as shown in Figure 1; a kind of moulding press is without magnetic field protection arrangement; comprise press control circuit 3 and hollow magnetizing coil 1, electromagnetic relay switch 2; described press control circuit 3 is used for being controlled to the Kai Heguan of swaging machine; hollow magnetizing coil 1 is used to provide the magnetic field in press-molding process, and described hollow magnetizing coil 1, electromagnetic relay switch 2 and press control circuit 3 are connected on power circuit successively.
In actual use, when hollow magnetizing coil 1 has magnetic field, electromagnetic relay switch 2 closes the utility model, and press control circuit 3 is energized, and controls press and normally works; When hollow magnetizing coil 1 is without magnetic field, electromagnetic relay switch 2 disconnects, and press control circuit 3 also disconnects, and moulding press does not work, prevent moulding press without during magnetic field produce substandard product.
Claims (2)
