Description
Magnetischer flexibler Schichtkörper Die Erfindung betrifft magnetische Schichtkörper, die aus Dauermagnetpulver und einem ummagnetischen Bindemittel hergestellt werden, z. B. Preßmagnete oder solche, die zunächst in Form mehr oder weniger flexibler Platten oder Bänder hergestellt werden, aus denen die endgültigen Magnetformen ausgeschnitten oder ausgestanzt werden.Magnetic Flexible Laminated Body The invention relates to magnetic ones Laminated body made from permanent magnet powder and a non-magnetic binder be e.g. B. press magnets or those that are initially more or less flexible in shape Plates or tapes are made from which the final magnet shapes are cut out or punched out.
Solche Magnete benötigen häufig Polstücke oder Rückschlußstücke aus Weicheisen. Es ist bekannt, diese Eisenteile bei der Herstellung in die Preßform einzulegen oder die gepreßten oder ausgestanzten Magnete mit ihnen, z. B. durch Kleben, zu verbinden.Such magnets often require pole pieces or back yoke pieces Soft iron. It is known to put these iron parts in the mold during manufacture insert or the pressed or punched magnets with them, z. B. by Gluing, connecting.
Die Erfindung zeigt einen besonders vorteilhaften Weg zur Herstellung solcher mit magnetisch weichen Leitstücken versehenen Dauermagnete. Sie ist dadurch gekennzeichnet, daß auch die magnetisch weichen Leitstücke aus Eisenpulver und einem ummagnetischen Bindemittel bestehen.The invention shows a particularly advantageous way of production such permanent magnets provided with magnetically soft conductive pieces. She is through it characterized in that the magnetically soft conductive pieces made of iron powder and one Ummagnetic binders exist.
Als Ausführungsbeispiel der Erfindung ist in der Zeichnung eine Magnetleiste dargestellt, die besonders bei Schrankverschlüssen Verwendung findet und auf ferromagnetischen Unterlagen haftet. Der dauermagnetische Teil t dieser Leiste besteht aus einem gepulverten Dauermagnetwerkstoff mit hoher Koerzitivkraft, z. B. Alnico oder B a0 - 6 Fez03 mit einem ummagnetischen Bindemittel, z. B. Gummi oder flexiblem oder hartem Kunststoff. Mit ihm verbunden ist das Leitstück 2, das aus Eisenpulver und einem der erwähnten Bindemittel besteht. Beide Teile sind zunächst einzeln als Bänder oder Profile gespritzt oder als Platten gewalzt und dann durch Aufwalzen, Aufkleben, Aufpressen oder eine ähnliche Behandlung miteinander verbunden worden. Die so hergestellten Verbundbänder bzw. Profile können unmittelbar als Haftleisten nach der Zeichnung verwendet werden, die Verbundplatten können zu solchen zerschnitten werden. Die Magnetisierung solcher Haftleisten erfolgt in bekannter Weise in Bogenform, so daß die Haftfläche magnetische Nord- und Südpole aufweist.As an embodiment of the invention, a magnetic strip is shown in the drawing shown, which is used especially for cabinet locks and on ferromagnetic Documents is liable. The permanent magnetic part t of this bar consists of a powder-coated one Permanent magnet material with high coercive force, e.g. B. Alnico or B a0 - 6 Fez03 with a non-magnetic binder, e.g. B. rubber or flexible or hard plastic. Connected to it is the guide piece 2, which is made of iron powder and one of the mentioned Binder consists. Both parts are initially injected individually as strips or profiles or rolled as plates and then by rolling, gluing, pressing or a similar treatment has been linked. The composite tapes produced in this way or profiles can be used directly as adhesive strips according to the drawing, the composite panels can be cut into such. The magnetization of such Adhesive strips are made in a known manner in arch form, so that the adhesive surface is magnetic Has north and south poles.
Die Erfindung ist von besonderer Bedeutung bei dauermagnetischen Werkstoffen, die zunächst in Form von Platten gewalzt werden und gepulverten Dauermagnetwerkstoff von der Art des Ba0 - 6 Fez0, enthalten. Die Teilchen dieses Magnetwerkstoffes sind magnetisch anisotrop und besitzen die Form von sechseckigen Plättchen; die bevorzugte Magnetisierungsrichtung steht senkrecht auf der Ebene dieser Plättchen. Beim Walzen ordnen sich die Plättchen in die Plattenebene, so daß der fertige Magnetwerkstoff eine bevorzugte Magnetisierungsrichtung senkrecht zur Plattenebene aufweist (3 in der Zeichnung). Bei bogenförmiger Magnetisierung einer aus einer solchen anisotropen Platte herausgeschnittenen Leiste würde der Magnetfluß einen Teil seines Weges in 1 senkrecht zu der Anisotropierichtung verlaufen, so daß die dem Werkstoff eigene hohe magnetische Güte nicht voll ausgenutzt würde. Erfindungsgemäß wird nun eine solche Platte mit einem Rückschlußteil2 verbunden, das in gleicher Weise wie Teil l hergestellt ist, aber statt dauermganetischem ein weichmagnetisches Eisenpulver enthält. In diesem Rückschlußteil2 kann der Magnetfluß ungehindert quer zur Anisotropierichtung des Teiles 1 verlaufen, so daß dieses in seinem ganzen Volumen bis zum Höchstwert aufmagnetisiert werden kann. Es resultiert eine beträchtliche Vergrößerung der Haftkraft der so hergestellten Magnete.The invention is of particular importance in permanent magnetic materials, which are initially rolled in the form of plates and powdered permanent magnet material of the type of Ba0 - 6 Fez0. The particles of this magnetic material are magnetically anisotropic and have the shape of hexagonal plates; the preferred The direction of magnetization is perpendicular to the plane of these platelets. When rolling arrange the platelets in the plane of the plate, so that the finished magnetic material has a preferred direction of magnetization perpendicular to the plane of the plate (3 in the drawing). With arcuate magnetization one of such anisotropic Plate cut out bar would make the magnetic flux part of its way in 1 run perpendicular to the anisotropy direction, so that the material inherent high magnetic quality would not be fully exploited. According to the invention is now a such a plate connected to a back yoke part2, which is in the same way as part l is manufactured, but instead of permanent organic a soft magnetic iron powder contains. In this return path part 2, the magnetic flux can unhindered transversely to the anisotropy direction of the part 1 run so that this in its entire volume up to the maximum value can be magnetized. The result is a considerable increase in the adhesive force of the magnets produced in this way.
