Description

Die Erfindung betrifft ein Verfahren und eine Einrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method and a device according to the preamble of claim 1.

In den Währungen verschiedener Staaten werden Münzen als Zahlungsmittel geprägt, die aus zwei Teilen, einem Ring oder Außenteil und einem Kern oder Innenteil bestehen, die dann auch aus unterschiedlichen Werkstoffen gefertigt sein können.In the currencies of different countries, coins are minted as a means of payment, which consist of two parts, a ring or outer part and a core or inner part, which can then also be made of different materials.

Die Herstellung dieser mitunter auch als Bi-Metall-Münzen benannten Geldstücke, wie auch die Herstellung zweiteiliger Medaillen erfolgt auf Stanzpressen mit entsprechenden Werkzeugen für die Außenform und die Innenform der Ring-Ronde als einem Ausgangsteil und auf Stanzpressen mit entsprechenden Werkzeugen für die Außenform der Kern-Ronde als zweitem Ausgangsteil für die Münze bzw. Medaille. Für einen ggf. geforderten erhabenen Rand der Ring-Ronde ist ein Stauchvorgang in einer Stauch- bzw. Rollmaschine erforderlich. Die Innenform -Kernloch- der Ring-Ronde ist für das Einfügen und die feste Verbindung mit der Kern-Ronde bei einem Fügevorgang auszuformen. Hierzu ist dann auch der Außenumfang der Kern-Ronde durch einen Stauchvorgang mit einem erhabenen Rand bzw. einer Wulst zu versehen, die die Form des Kernloches der Ring-Ronde beim Fügen ausfüllen muß. Ring-Ronde und Kern-Ronde werden nacheinander einem schrittweise drehgetriebenen Revolverteller zugeführt. Die Zufuhr erfolgt über entsprechende Zuführ-/Vereinzelungseinrichtungen, wie es aus der DE 37 42 745 A1 zu ersehen ist. Hierbei wird die Kern-Ronde in die zuvor in dem Revolverteller vereinzelt abgelegte Ring-Ronde eingelegt und bei weiterer Drehung des Revolvertellers mit der Ring-Ronde der Fügestation zugeführt.The manufacture of these coins, sometimes also called bi-metal coins, as well as the production of two-part medals is carried out on punch presses with appropriate tools for the outer shape and the inner shape of the circular blank as an initial part and on punch presses with corresponding tools for the outer shape of the core -Ronde as a second starting part for the coin or medal. An upset process in an upset or rolling machine is required for a raised edge of the circular blank that may be required. The inner shape - core hole - of the circular blank is to be shaped for the insertion and the firm connection with the core blank during a joining process. For this purpose, the outer circumference of the core blank is then to be provided with a raised edge or a bulge by means of an upsetting process, which must fill the shape of the core hole of the ring blank during joining. Ring-blank and core-blank are successively fed to a step-by-step rotary turret. The feed takes place via corresponding feed / separation devices, as can be seen from DE 37 42 745 A1. In this case, the core blank is inserted into the ring blank previously stored individually in the turret plate and, when the turret plate is rotated further, is fed with the ring blank to the joining station.

Diesem insgesamt bekannten, da ausgeführten Stand der Technik gegenüber ist es Aufgabe der Erfindung, die ungelochte Ring-Ronde dem Revolverteller zuzuführen und in Drehbewegung des Revolvertellers, auch als nächste Bearbeitungsstufe eine Stanzpresse mit einem Werkzeug für die Kernlochung der Ring-Ronde und ggf. weiterer Innenformung der Ring-Ronde vorzusehen.In relation to this generally known state of the art, it is the object of the invention to feed the unperforated ring blank to the turret plate and, in the rotational movement of the turret plate, also as a next processing step, a punch press with a tool for the core perforation of the ring blank and possibly further To provide internal shaping of the circular blank.

Diese Aufgabe ist gelöst durch die gegenständlichen Merkmale des Anspruchs 1. Die weiteren Ansprüche stellen für sich erfinderische Ausgestaltungen dar.This object is achieved by the objective features of claim 1. The other claims are inventive developments.

Von besonderem Vorteil ist hierbei die Nutzung des Revolvertellers als Zubringer zwischen der Stanzpresse mit dem Werkzeug für die Außenform der Ring-Ronde und der Stanzpresse mit dem Werkzeug für das Kernloch der Ring-Ronde bei gleichzeitigem Wegfall des bisher notwendigen Aufwands an Zwischenlagerung und Transport der gelochten Ring-Ronde.It is particularly advantageous to use the turret plate as a feeder between the punch press with the tool for the outer shape of the ring blank and the punch press with the tool for the core hole of the ring blank, while at the same time eliminating the previously required effort for intermediate storage and transport of the perforated holes Ring disc.

Mit Pfeil 1 ist eine Stanzpresse angedeutet mit einem Werkzeug 2 zum Ausstanzen (Außenform) der Ring-Ronde 3. Bei diesem Stanzvorgang aus einem Blechstreifen wird die Ringronde 3 in einem Behältnis aufgefangen und vermittels einer Zuführ-/Vereinzelungsstufe 26, in den Fign. 2, 3, ohne Verprägung des Randes 4 der Zuführstufe 21 in einem Revolverteller 20 zugeführt. Ist demgegenüber die Ring-Ronde 3 mit einem erhabenen Rand 7 zu versehen, erfolgt eine Bearbeitung des Randes (Außenform) in z.B. einer Stauchmaschine 5 mit dem Roll-Werkzeug 6.In Fig. 1, the individual process steps for the production of ring-core coins and medals are shown. Arrow 1 indicates a punch press with a tool 2 for punching out (outer shape) the ring blank 3. During this punching process from a sheet metal strip, the ring blank 3 is caught in a container and is conveyed by means of a feed / separation stage 26, in FIGS. 2, 3, fed into a turret plate 20 without embossing the edge 4 of the feed stage 21. If, on the other hand, the circular blank 3 is to be provided with a raised edge 7, the edge (outer shape) is machined in e.g. an upsetting machine 5 with the rolling tool 6.

Die von dem Revolverteller aufgenommene Ring-Ronde 3 wird durch Drehung des Revolvertellers der Lochstufe 22 mit dem Werkzeug 9 einer Stanzpresse 8 zugeführt. Die Lochung des Kernloches erfolgt in den Toleranzen einer nachfolgend einzulegenden Kern-Ronde 13. Sind für die Verbindung zwischen Ring-Ronde und Kern-Ronde bestimmte Arretier- und Festigkeitsvorschriften einzuhalten, ist das Kernloch in der Lochstufe z.B. durch ein Folgewerkzeug nachzuarbeiten (EP 0 080 437 A1), während die Kern-Ronde mit einem entsprechenden erhabenen Rand zu versehen ist. Die in den Revolverteller in der Lochstufe erneut zurückgeführte Ring-Ronde wird durch Drehung des Revolvertellers der Zuführstufe 23 zugeführt. In dieser Zuführstufe wird eine Kern-Ronde 13 in das Kernloch 10 der Ring-Ronde eingelegt. Die Kern-Ronde ist zuvor in einem Werkzeug 12 einer Stanzpresse 11 aus einem Blech ausgestanzt (Außenform) worden und danach direkt der Zuführstufe 23 zugeführt. Im Hinblick auf die Form des Kernloches 10 der Ring-Ronde 3 ist ggf. die Kern-Ronde in einer Stauchmaschine 15 mit dem Roll-Werkzeug 16 mit einem erhobenen Rand 17 zu versehen und erst daran anschließend der Zuführstufe 23 im Revolverteller zuzuführen. Durch Drehung des Revolvertellers werden die Ring-Ronde und die in diese eingelegte Kern-Ronde der Fügestufe 24 zugeführt. Die Fügestufe weist eine Stanzpresse 18 auf mit dem Fügewerkzeug 19 zum Verbinden der Ring-Ronde mit der Kern-Ronde.The ring disc 3 received by the turret plate is fed to a punch press 8 by rotating the turret plate of the hole step 22 with the tool 9. The core hole is punched in the tolerances of a core blank 13 to be inserted below. Are for the To comply with certain locking and strength regulations, the core hole in the perforation step must be reworked, for example by a follow-up tool (EP 0 080 437 A1), while the core blank is to be provided with a corresponding raised edge. The ring blank which is fed back into the turret plate in the perforated step is fed to the feed step 23 by rotating the turret plate. In this feed stage, a core blank 13 is inserted into the core hole 10 of the ring blank. The core blank has previously been punched out of a metal sheet (outer shape) in a tool 12 of a punch press 11 and then fed directly to the feed stage 23. With regard to the shape of the core hole 10 of the ring blank 3, the core blank may have to be provided with a raised edge 17 in an upsetting machine 15 with the rolling tool 16 and only then be fed to the feed stage 23 in the turret plate. By rotating the turret plate, the ring blank and the core blank inserted into it are fed to the joining stage 24. The joining stage has a punch press 18 with the joining tool 19 for connecting the ring blank to the core blank.
