Definitions

  • the invention relates to a method for producing two-piece coin blanks, consisting of an inner disc and an outer ring pressed therewith; with the steps: punching out ring and disc; Insert the disc into the ring, as well as on a two-part coin blank consisting of an inner disc and an outer ring pressed with it.
  • coins have been known and put into circulation which consist of two composite components with different physical properties, for example different colors, in such a way that an inner circular Disc is surrounded by an outer ring.
  • Bicolor coins which consist of an outer ring and a different colored disc-shaped core, are in circulation in Italy (500 fire), France (10 FF), Portugal (100 Esc) and Thailand (10 baht). To produce the blank, disk-shaped platelets are usually punched from one and rings from another band or sheet.
  • the core consists of "white” nickel and a yellow ring made of a copper alloy with aluminum and nickel additions (10 FF), or the ring consists of stainless steel and the core made of a yellow copper alloy (500 fire) with Aluminum and nickel additives, or the ring consists of "white” copper nickel and the core of a copper alloy with aluminum and nickel additives (100 Esc, 10 Baht).
  • Ring and core are joined together using known methods.
  • EP 0 080 437 A1 the inside of the outer ring has a taper before being joined to form the coin blank, on which are attached lugs which prevent twisting of the inner part in the outer ring after the joining.
  • the French 10 FF piece has an outer diameter of 23 mm, inner diameter of the ring and core diameter are 16 mm. Punching out the slug means that half the weight of the disc from which the ring is produced is lost.
  • this also means a high manufacturing outlay, of which a large proportion is destroyed again by scrapping the slug, because coin systems in which the slug obtained is used for a different coin value within the system containing the two-tone coin not yet known.
  • the object of the present invention is to optimize the achievable material utilization rate in the production of two-part coin blanks and at the same time to reduce the production costs of the blank.
  • this object is achieved in that the ring and the disk consist of the same base material and that at least one of the components of the outer ring and the inner disk is colored permanently.
  • the slug is recycled instead of being scrapped, and not only the material is reintroduced into the manufacturing process, as was customary hitherto, significant economic advantages are achieved.
  • the value of the slug which can no longer be used in previously known processes is determined not only by the metal value, but in particular also by the production costs for the strip or sheet metal from which the ring and the inner disk are manufactured. Because, according to the invention, the scrapping, and likewise the production of new metal sheets from the material obtained by scrapping, are eliminated, a considerable reduction in the production costs can be achieved.
  • the slug obtained when the ring 3 is produced from the strip or sheet 1 by punching on the punching line 2a, 2b is used as the inner core 4.
  • the diameter d of the disk 4 is slightly reduced by a knurling process in order to make it easier to insert the inner disk into the outer ring 3.
  • the slug diameter d can namely be slightly larger (approx. 0.1 mm) than that due to deformation Inner diameter D of the ring.
  • changes in shape of the Edge are made, which are desired for the assembly of the components "ring” and "inner disc".
  • either the slug 4 or the ring 3 is given a different color, e.g. by metallic coloring or coating with different colored metals, e.g. by electroplating.
  • a coin according to the invention therefore consists of a uniform base material.
  • All metals that can be permanently colored by any process can be considered as a uniform base material for the production of ring and core. It is irrelevant whether the color of the base material is retained for the ring or for the core and whether the corresponding counterpart (core or ring) is colored. Finally, e.g. both ring and core can be colored by electroplating with different colored metals.
  • the coating of the ring with corrosion-resistant nickel protects the steel rim, which is not corrosion-resistant against moisture, without additional effort.
