Description

Verfahren zur Herstellung von Masseeisen-Bauteilen von Hochfrequenzgeräten In der Hochfrequenztechnik werden Masseeisenkerne benötigt, die mitIsolationswerkstoff umpreßt oder in solchen eingedrückt oder mit solchen mechanisch verbunden oder aneinandergek :lebt sind. Hierzu sind bis dahin eine Anzahl von Arbeitsgängen notwendig, die verteuernd auf die aufzubauenden Hochfrequenzgeräte wirken. Der Zweck der Erfindung besteht darin, diese Maßnahmen zu vereinfachen und damit die Herstellung von Bauteilen für Hochfrequenzgeräte zu verbilligen, indem gemäß dem neuen Verfahren ein Kern aus Masseeiseri mit einem Teil aus Isolationswerkstoff durch gemeinsame Pressung verbunden wird. Gemäß der Erfindung geschieht das Ansetzen eines Teiles, z. B. eines Halterungselementes, aus Isolationswerkstoff an einen Kern aus Masseeisen folgendermaßen: Die vorbereiteten Preßmischungen des Masseeisens sowohl als die des vorzugsweise keramischen Isolationswerkstoffes liegen in Pulverform vor. Das Masseeisenp,ulverwird zunächst in die Form gefüllt und mit etwa dem zehnten Teil des endgültig notwendigen Druckes vorgepreßt. Dann wird das Praßpulver des Isolationswerkstoffes in die Form zu dem vorgepreßten Masseeisen getan, worauf die Form unter den endgültigen Druck gesetzt wird, der für die Herstellung des gewünschten Formlings erforderlich ist. Dieser wird dann im Trockenofen gehärtet.Process for the production of solid iron components for high-frequency devices In high-frequency technology, ground iron cores are required with insulation material pressed around or pressed into such or mechanically connected to such or to one another : lives are. For this purpose, a number of operations are necessary until then, which make them more expensive act on the high-frequency devices to be set up. The purpose of the invention is is to simplify these measures and thus the production of components for Cheaper high-frequency devices by making a core according to the new process Masseeiseri connected to a part made of insulation material by pressing together will. According to the invention, the attachment of a part happens, for. B. a mounting element, made of insulation material to a core made of ground iron as follows: The prepared Press mixtures of the ground iron as well as that of the preferably ceramic insulation material are in powder form. The ground iron paste is first filled into the mold and pre-pressed with about a tenth of the final necessary pressure. then the molding powder of the insulation material is in the form of the pre-pressed mass iron done after which the mold is placed under the final pressure required to manufacture it of the desired molding is required. This is then hardened in the drying oven.

Das gepreßte Stück zeigt trotz der verschiedenen spezifischen Gewichte der beiden Pulver eine so enge durch den Preßvorgang erreichte Verbindung, daß eine Trennung des Masseeisens vom Isolationsstoff durch . mechanische Beanspruchungen; die normalerweise im Gerätebau auftreten, nicht möglich ist.The pressed piece shows despite the different specific weights of the two powders so close a bond achieved by the pressing process that one Separation of the ground iron from Insulation material through. mechanical Stresses; which normally occur in device construction is not possible.

Während im vorstehenden .Beispiel das. neue Verfahren für die Herstellung eines Masseeisenkernes mit angesetztem Isolationsstück beschrieben ist, können in .gleicher oder analoger Weise auch andere Bauteile gfür Hochfrequenzgeräte gemeinsam aus Masseeisen- und keramischen Werkstoffpulvern gepreßt werden.While in the above .Example the. New process for the production a ground iron core with attached insulation piece is described in .In the same or analogous manner, other components for high-frequency devices are also common are pressed from cast iron and ceramic material powders.
