Description

Verfahren zur Formgebung von Teilen aus natürlichem Speckstein Die gute Bearbeitbarkeit von natürlichem Speckstein ,durch Drehen, Bohren, Sägen und Fräsen hat man für die Herstellung mannigfacher Formteile aus Speckstein ausgenutzt. Durch eine Glühbehandlung nach der Bearbeitung erhalten die Formteile ein. fast dichtes Gefüge und erhebliche Härte. Die dabei auftretende Schwindung ist im Vergleich zur keramischen Fertigung sehr gering, @so daß die Specksteinformteile sich durch große Maßgenauigkeit auszeichnen. Außerdem hat der geglühte Specksteineinen hohen Isolationswiderstand und verhältnismäßig geringe dielektrische Verluste, s o d@aß er für elektrische Isolierkörper recht geeignet ist.Method of shaping parts from natural soapstone Die natural soapstone can be easily machined by turning, drilling, sawing and Milling has been used for the production of various molded parts from soapstone. The molded parts are given an annealing treatment after processing. nearly dense structure and considerable hardness. The shrinkage that occurs is in comparison for ceramic production very low, @ so that the soapstone moldings through characterized by great dimensional accuracy. In addition, the glowed soapstone has a high Insulation resistance and relatively low dielectric losses, s o d @ aß it is quite suitable for electrical insulators.

Die bisher benutzten Bearbeitungsverfahren (Drehen, Bohren, Sägen, Fräsen) genügen in vielen Fällen, um auch leomplizierte Formteile in Einzelanfertigung herzustellen. Um die Formgebungsmöglichkeiten des natürlichen Specksteins zu erweitern, wird nach der Erfindung vorgeschlagen, Speckstei#ntei5l# e-le- geringer Wandstärke durch Ausstanzen zu bearbeiten. Überraschenderweise hat sich nämlich gezeigt, daß der Speckstein, in Form dünner Scheiben ausgezeichnet stanzfähig ist und beim Ausstanzen genaue, scharfkantige und von Ausbröckelungeu freie Formteile ergibt. Die Weichheit des Specksteins bietet überdies den Vorteil, daß die zum Ausstanzen benutzten Schnitte nur geringer Abnutzung unterworfen sind.The machining processes used so far (turning, drilling, sawing, Milling) is sufficient in many cases to produce complex molded parts as well to manufacture. In order to expand the shaping possibilities of natural soapstone, is proposed according to the invention, soapstone # ntei5l # e-le- low wall thickness edit by punching. Surprisingly, it has been shown that the soapstone, in the form of thin slices, is excellent for punching and when punching out results in precise, sharp-edged molded parts free of crumbling. The softness The soapstone also has the advantage that the cuts used for punching are only subject to slight wear and tear.

Das Verfahren gemäß der Erfindung bietet unter anderem die Möglichkeit, Abstands!scheiben für den Elektronenröhrenbau aus dem einheimischen Specksterin wirtschaftlich herzustellen, während man hierfür bisher ausländischen Blattglimmer nötig hatte. Daß die Hitzdbeständigkeit der Specksteinscheiiben größer ist als diel der Glimmerscheiben; ist bei idiesem Verwendungszweck noch ein besonderer Vorteil.The method according to the invention offers, inter alia, the possibility Spacer washers for the Electron tube construction from the local Specksterin can be produced economically, while this has hitherto been used abroad Needed sheet mica. That the heat resistance of the soapstone panes is greater is as the diel of the mica washers; is a special one for this purpose Advantage.

Bei der Durchführung des Verfahrens nach der Erfindung geht man von dünnen Scheiben aus Specksteine aus, welche man in gewähnter Weise durch Abstechen oder Sägen gewinnt. Es bietet keine besonderen Schwierigkeiten, auf ,diese Weise Seheiben von nur einigen Zehntelmillimeter Stärke herzustellen. Auch manche Talke, welche infolge ihrer ,blättrigem Struktur gut spaltbar sind, können für die- Herstellung der Scheiben benutzt wenden.When carrying out the method according to the invention, one proceeds from thin slices of soapstone, which can be cut in the usual way or sawing wins. It presents no particular difficulty in doing that To produce slices only a few tenths of a millimeter thick. Also some talks, which are easily cleavable due to their leafy structure, can be used for the production of the discs used.

Aus derartigen Scheiben von beispielsweise 0,2 bis o,5:mm Dicke werden dann in einem einzigen Arbeitsgang die Formteile herausgestanzt. Es gelingt aber auch, stärkere Specksteinscheiben durch Ausstanzen zu bearbeiten, wenn man durch entsprechende Unterteilung der :Arbeitsgänge und Anpassung der Schnittwerkzeuge dafür - sorgt, daß desi Materiial quer zur Stanzrichtung nicht ausweichen kann. Beispielsweise stanzt man zunächst nur den Formteil seinem Umriß nach' heraus und stanzt dann mittels eines zweiten Schnittwerkzeuges, welches dem Umriß des Formteils entsprechende: in Stanzrichtung verlaufende, Anlageflächen hat, in einem zweiten. Arbeitsgang die Löcher des Formteils heraus:Such disks with a thickness of, for example, 0.2 to 0.5: mm become then punched out the molded parts in a single operation. But it works also, to machine thick soapstone slices by punching out, if you go through appropriate subdivision of: operations and adaptation of the cutting tools ensures that the material cannot move across the punching direction. For example, you first just punch out the shape of the molded part and then punches by means of a second cutting tool, which corresponds to the outline of the molded part corresponding: running in the punching direction, has contact surfaces, in a second. Step out the holes of the molded part:
