Abstract

Zur Fertigung von Bimetallmünzen wird häufig ein Kern (5) in einen Ring (3) eingelegt und diese werden dann zusammen verpresst und ggfs. geprägt. Auch wenn der Kern (5) und der Ring (3) nur gefügt werden sollen, die Prägung aber woanders stattfindet, ist für das Fügen (7) zur zeitweiligen Fixierung eine Prägemaschine mit relativ hohem apparativem Aufwand erforderlich. Die Erfindung hilft hier ab, indem in dem Vorfügeprozess ein- oder mehrere Laserschweißpunkte (29a,29b,29c,29d) oder gar eine durchgezogene Naht erzeugt werden. Das Ziel dieser Verbindung ist zunächst, nur den Kern (5) und den Ring (3) so lange zusammenzuhalten, bis diese nach einem Sortierprozess in die Prägepresse vereinzelt werden. Werden die Kerne nur in die Ringe gepunktet, können sehr hohe Taktzahlen von über 700 Stück/min erreicht werden. Der Laserkopf muss nicht verfahren werden.

For the production of bimetal coins, a core (5) is often placed in a ring (3) and these are then pressed together and, if necessary, minted. Even if the core (5) and the ring (3) are only to be joined, but the embossing takes place elsewhere, an embossing machine with a relatively high outlay on equipment is required for the joining (7) for temporary fixation. The invention remedies this by creating one or more laser welding spots (29a, 29b, 29c, 29d) or even a solid seam in the joining process. The aim of this connection is initially to hold together only the core (5) and the ring (3) until they are separated into the embossing press after a sorting process. If the cores are only dotted into the rings, very high cycle rates of over 700 pieces / min can be achieved. The laser head does not have to be moved.
