Definitions

  • the present invention relates to a process for the production of monetary coins and bimetallic medals.
  • the present invention relates to a process for manufacturing bimetallic coins or medals, by securing a crown with an insert, which aims to overcome the difficulties encountered in the implementation of the process described in EP-A-0 080 437.
  • the method according to the invention aims to remedy the drawbacks of known methods, and avoids, in particular, having the need to use two successive strikes to achieve each coin or each medal.
  • the invention in a first aspect, relates to a process for the production of monetary coins or bimetallic medals each obtained by the use of a crown comprising an internal opening and an insert of appropriate size to be inserted into said opening, one of the crown and insert elements comprising securing means, said insert is placed in the opening of said crown and the insert and said crown are crimped at least in part thanks to the securing means , by causing plastic deformation of the material of one of the elements of said crown - insert assembly in the free space existing between said elements, and finally a minting operation by stamping, characterized in that a section crown is used substantially rectangular straight line whose initial thickness is greater than the initial thickness of the insert and in what is produced in a single the operation the crimping of the crown - insert assembly and the coin minting using a matrix whose action causes said plastic deformation of the crown material towards the insert and the stamping of the crown - insert assembly for form the surface of the coin or medal.
  • the invention also covers, according to a second aspect, monetary coins or medals comprising a crown comprising an internal opening and an insert disposed in said opening and secured to it by means of securing, characterized in that the crown is initially of 'A substantially rectangular cross section and has a thickness greater than the initial thickness of the insert, the connection being obtained by plastic deformation of the material from the crown to the insert.
  • the invention also covers a crown and an insert for the manufacture of monetary coins or bimetallic medals by crown and insert, characterized in that the crown initially has a substantially rectangular cross section and a thickness greater than the initial thickness of the insert, preferably greater than 0.05 to 0.3 millimeter.
  • the materials, the shape and the dimensions of the insert and of the crown are, of course, appropriate to choose the materials, the shape and the dimensions of the insert and of the crown.
  • the metal any of the metals or alloys which can be used in the monetary field or for making medals can be used, but the metal (or alloy) constituting the crown must be more ductile than that used for the insert; it is indeed the metal (or alloy) constituting the crown which, under the influence of the pressure exerted must deform plastically to at least partially fill the groove formed in the insert while the deformation of the insert must limit to the surface deformation corresponding to the formation of the reliefs and / or figures chosen for the coin or medal.
  • inserts and crowns will be used, the clearance (distance between the outer part of the insert and the inner part of the crown) being between approximately 0.05 and about 0.2 millimeter; in addition, the crown will have a thickness of 0.05 to 0.3 millimeter greater than that of the insert.
  • Figure 1 (a and b) is a view of the two elements (crown and insert) usable according to the invention.
  • Figure 2 is a view, in partial section, of the two elements (crown and insert) suitably positioned.
  • Figure 3 is a view, in partial section, of the finished part.
  • Figure 1a shows in partial section the "crown"; as can be seen, this crown has a rectangular cross section; it can have, for example, an outside diameter of 23 mm, an inside diameter of 16.5 mm and a thickness of 2.5 mm.
  • This crown is obtained by cutting the strip. It then undergoes pickling annealing and brightening operations specific to the alloy used.
  • Figure 1b shows the insert. It is an insert in the shape of a circular disc, obtained by cutting, the diameter of which is 16.3 mm and the thickness of 2.4 mm.
  • This insert undergoes a cording operation of the "incuse edge" type which makes it possible to obtain a series of grooves; each groove has a maximum depth of the order of 0.2 mm. For example, 6 or 8 grooves will be made around the periphery of the insert.
  • This insert can also undergo pickling annealing and polishing operations specific to the alloy used.
  • Figure 3 there is shown a finished part; that is to say that the two elements positioned as in FIG. 3 have been conveyed towards the striking dies (or corners); this striking ensures in a single operation the crimping obtained by plastic deformation of the metal (or alloy) of the crown towards the insert and in particular towards the grooves thereof, and the coinage.
