Abstract

Es sind verschiedene Methoden bekannt, Preßlinge im Magnetfeld herzustellen. Bei einer dieser Herstellungs­ arten wirkt die Preßkraft normal zum Magnetfeld. Various methods are known for pressing compacts in To produce a magnetic field. In one of these manufacturing the press force is normal to the magnetic field.

Aufgabe der Erfindung ist es, eine Einrichtung zu schaffen, mit der im Preßraum ein möglichst hohes und homogenes Magnetfeld erreicht wird. The object of the invention is to provide a device create with the highest possible in the press room homogeneous magnetic field is reached.

Gemäß der Fig. besteht die Matrize aus vier Teilen (2 bzw 3), wobei die Teile (2) aus einem Material bestehen das einen hohen magnetischen Leitwert oder umgekehrt aufweisen. Der Preßraum (4) kann auch mit Formstücken ausgekleidet sein, deren Material äquivalent dem der Teile (2, 3) ist. According to the figure, the die consists of four parts (2nd or 3), the parts (2) being made of one material that has a high magnetic conductance or vice versa exhibit. The press room (4) can also be used with fittings be lined, the material of which is equivalent to that of Parts (2, 3).

Der Vorteil der Erfindung ist, darin zu sehen, daß der hergestellte Preßling (7) optimale magnetische Eigen­ schaften aufweist. The advantage of the invention is that the produced compact (7) optimal magnetic eigen features.
