Abstract
Description
Die Erfindung bezieht sich auf einen zweiteiligen Rohling für Münzen, Medaillen, Wertmarken, Spielmarken und dergleichen, bestehend aus einer inneren Scheibe aus einem ersten Metall oder einer Metall-Legierung, die in die zentrale Öffnung eines äußeren Rings aus einem zweiten Metall oder einer zweiten Metall-Legierung eingepreßt ist.The invention relates to a two-piece blank for coins, medals, tokens, tokens and the like, consisting of an inner disk made of a first metal or a metal alloy, which is in the central opening of an outer ring made of a second metal or a second metal Alloy is pressed in.
In der Vergangenheit sind Münzen hauptsächlich aus massivem Metall einheitlicher Zusammensetzung aus einem Stück hergestellt worden. Darüber hinaus werden Münzen auch aus unterschiedlichen Metallen und Metallegierungen hergestellt. Es handelt sich dabei überwiegend um Schichtverbundwerkstoffe, wie sie beispielsweise durch Walzplattieren eines Stahlkerns mit einer beidseitigen Auflage aus Messing hergestellt werden. In jüngerer Vergangenheit finden für die Herstellung von Münzen zunehmend auch solche Werkstoffverbunde Anwendung, die aus einer inneren Scheibe aus einem Metall bestehen, welche von einem äußeren Ring aus einem anderen Metall oder aus einer anderen Metallegierung umgeben ist. So besteht die italienische 500-Lire-Münze aus einer inneren Scheibe aus einer goldfarbenen Kupferlegierung. Konzentrisch um diese innere Scheibe ist ein äußerer Ring aus einem bläulich schimmernden silbergrauen Chromstahl gepreßt. Die schnellaufenden Prägemaschinen nach heutiger Maschinentechnik, mit denen diese Werkstoffverbunde mit tragbarem Aufwand auch in großen Stückzahlen hergestellt werden, erfordern bei der Herstellung der Komponenten eines solchen konzentrischen Werkstoffverbunds besondere Aufmerksamkeit. Besondere Maßnahmen sind daher erforderlich, um beim Prägen einen gut aneinander haftenden Verbund der inneren Scheibe und des äußeren Ringes zu erzielen.In the past, coins were mainly made from one piece of solid metal of uniform composition. In addition, coins are also made from different metals and metal alloys. These are mainly layered composites, such as those produced by roll cladding a steel core with a brass support on both sides. In the recent past, such material composites have increasingly been used for the production of coins consist of an inner disc made of a metal, which is surrounded by an outer ring made of another metal or a different metal alloy. The Italian 500 lire coin consists of an inner disc made of a gold-colored copper alloy. An outer ring made of a bluish shimmering silver-gray chrome steel is pressed concentrically around this inner disc. The high-speed embossing machines based on today's machine technology, with which these material composites can be manufactured in large quantities with a reasonable effort, require special attention when manufacturing the components of such a concentric material composite. Special measures are therefore necessary in order to achieve a good bond between the inner disc and the outer ring during embossing.
In der US-A- 3 499 739 wird vorgeschlagen, den äußeren Ring etwas dicker zu wählen als die innere Scheibe. Dadurch soll beim Prägevorgang der äußere Ring über die Kanten der inneren Scheibe gedrückt werden, um einen formschlüssigen Verbund der Scheibe und des Rings zu erreichen. Die JP-A- 58-3743 enthält den Vorschlag, die innere Scheibe oder alternativ den äußeren Ring mit einer umlaufenden Randnut zu versehen. Zum Zusammenfügen werden beide Komponenten ineinandergelegt, um mit Hilfe eines speziellen Werkzeugs Material der inneren Scheibe in die Nut im äußeren Ring oder umgekehrt zu pressen.In US-A-3 499 739 it is proposed to choose the outer ring somewhat thicker than the inner disc. This is intended to press the outer ring over the edges of the inner disk during the embossing process in order to achieve a positive connection between the disk and the ring. JP-A-58-3743 contains the proposal to provide the inner disk or alternatively the outer ring with a peripheral edge groove. To assemble the two components are placed one inside the other in order to use a special tool to press the material of the inner disk into the groove in the outer ring or vice versa.
Aus der EPA-A- 0 080 437 ist bekannt, den Innenrand des äußeren Ringes keilförmig zu gestalten und die innere Scheibe mit einem Randwulst zu versehen. Beim Prägevorgang kann dann Material aus diesem Wulst über den verjüngten Innenrand des äußeren Ringes fließen. Zugleich sind am Innenrand des äußeren Ringes noch mehrere hervorspringende Zähne vorgesehen, die sich beim Prägen in die innere Scheibe eindrücken sollen. So wird die Möglichkeit eines gegenseitigen Verdrehens von äußerem Ring und innerer Scheibe nach dem Prägen ausgeschlossen.From EPA-A-0 080 437 it is known to design the inner edge of the outer ring in a wedge shape and to provide the inner disk with an edge bead. During the embossing process, material from this bead can then flow over the tapered inner edge of the outer ring. At the same time, several protruding teeth are provided on the inner edge of the outer ring, which are during the stamping should press into the inner pane. This eliminates the possibility of the outer ring and inner disk twisting relative to one another after embossing.
Die EP-A- 0 160 343 greift diese Idee mit einem sehr ähnlich gestalteten äußeren Ring auf. Bei der aus der EP-A- 0 280 615 bekannten Münze wird in den äußeren Ring eine Kugel eingeführt und sodann plastisch zur inneren Scheibe umgeformt. Bei der EP-A- 0 415 892 wird der Innenrand des äußeren Ringes mit einer unterbrochenen Umfangsnut versehen, in die beim Prägevorgang dann Material der inneren Scheibe hineinfließt.EP-A-0 160 343 takes up this idea with a very similarly designed outer ring. In the case of the coin known from EP-A-0 280 615, a ball is inserted into the outer ring and then plastically formed into the inner disk. In EP-A-0 415 892 the inner edge of the outer ring is provided with an interrupted circumferential groove into which material of the inner disk then flows during the stamping process.
Während sich die Lehre der US-A- 3 499 739 für die praktische Anwendung als nicht ausreichend erwiesen hat und die Lehre der vorgenannten JP-A ein spezielles Werkzeug für das Zusammenfügen erfordert, haben die Lehren der EP-A- 0 080 437, 0 160 343 und 0 415 892 den Nachteil, daß der Innenseite des äußeren Ringes eine komplizierte geometrische Gestalt gegeben werden muß.While the teaching of US-A-3 499 739 has proven insufficient for practical use and the teaching of the aforementioned JP-A requires a special tool for assembly, the teaching of EP-A-0 080 437, 0 160 343 and 0 415 892 the disadvantage that the inside of the outer ring must be given a complicated geometric shape.
Überraschenderweise hat sich nun gezeigt, daß durch eine einfach vorzunehmende geeignete Formgebung des äußeren Randes der inneren Scheibe ein Verdrehen beider Teile und das Herausfallen der inneren Scheibe aus dem äußeren Ring nach dem Prägen sicher verhindert wird. Hierzu genügt es, den Außenrand der inneren Scheibe mit Vertiefungen in schräg gegeneinander gerichteter Anordnung zu versehen. Diese Vertiefungen können auch als schlangenförmige Nut ausgebildet sein. Dadurch wird das Fließen von Material des äußeren Teils in die Vertiefungen des inneren Teils erleichtert.Surprisingly, it has now been shown that twisting of both parts and falling out of the inner disk from the outer ring after the stamping is reliably prevented by a suitable shaping of the outer rim of the inner disk that is easy to carry out. For this it is sufficient to provide the outer edge of the inner pane with depressions in an obliquely directed arrangement. These depressions can also be designed as a serpentine groove. This facilitates the flow of material from the outer part into the depressions of the inner part.
In einer weiteren Ausgestaltung sieht die Erfindung vor, daß äußerer Ring und innere Scheibe des konzentrischen Münz-Werkstoffverbundes in ihrer elektrischen Leitfähigkeit weit auseinanderliegen. Das wird am besten dadurch erzielt, daß für den elektrisch gut leitenden Teil ein Kupfer-Münzwerkstoff mit einem spezifischen elektrischen Widerstand von max. 25µΩ·cm Anwendung findet. Für den elektrisch schlecht leitenden Teil soll ein Chrom- oder ein Chrom-Nickel-Stahl mit einem spezifischen elektrischen Widerstand von wenigstens 70µΩ·cm gewählt werden. Der elektrisch schlechter leitende Teil kann auch ein Schichtverbund aus ferritischem und austenitischem Stahl sein. Dadurch wird folgendes erreicht:
Die heutigen elektronischen Münzzprüfgeräte nutzen in unterschiedlicher Weise das Prinzip der elektromagnetischen Wechselwirkung zwischen elektromagnetischen Feldern verschiedener Frequenz und den Münzmetallen. Es lassen sich beim Durchlauf der Münzen durch die Spulensysteme von Münzprüfgeräten charakteristische Doppelsignale erzielen, sofern ein erheblich besser leitender Teil des Werkstoffverbundes den äußeren Ring bildet, oder alternativ ein Einzelsignal mit charakteristischer Kurvenform, wenn ein erheblich besser leitender Teil die innere Scheibe bildet.In a further embodiment, the invention provides that the outer ring and inner disc of the concentric coin material composite in their electrical Conductivity is far apart. This is best achieved by using a copper coin material with a specific electrical resistance of max. 25µΩ · cm is used. For the electrically poorly conductive part, a chrome or a chrome-nickel steel with a specific electrical resistance of at least 70µΩ · cm should be selected. The electrically poorly conductive part can also be a composite of ferritic and austenitic steel. This achieves the following:
Today's electronic coin validators use the principle of electromagnetic interaction between electromagnetic fields of different frequencies and the coin metals in different ways. Characteristic double signals can be obtained when the coins pass through the coil systems of coin validators, provided that a considerably better conductive part of the composite material forms the outer ring, or alternatively a single signal with a characteristic curve shape if a significantly better conductive part forms the inner disc.
