Definitions

  • the invention relates to a method and a device as well as circular blanks for making coins and medals from metal, including precious metal.
  • the invention is therefore based on the object of providing measures with the help of coins or medals with the least possible use of materials manufactured safely and reliably for a given outside diameter can be.
  • the invention provides with the features of characterizing part of claim 1 that first a sublime Core zone and a raised edge zone on at least one side Cold forming can be produced.
  • the disk-shaped body 2 is generally circular. Basically The same applies to the raised core zones 3, 3 '.
  • the edge zones 4, 4 ' are ring-shaped.
  • the intermediate zone 5 or 5 ' is in each case a ring zone.
  • the core zones 3, 3 'are flat elevations compared to the edge zones 4, 4 ', their flanks or in particular the flanks 6, 6 'of the core are relatively steep.
  • a such procedure appropriate, especially if for large The formed sheet 7 before punching the round blanks 1 to be annealed and polished.
  • the cross section is correspondingly smaller in the region of the intermediate zones 5, 5 ' than the cross section of the sheet 7, since material from the area the intermediate zones 5, 5 'to the core zones 3, 3' and the peripheral zones 4, 4 ' is shifted.
  • the cold forming does not necessarily have to be on the starting material or Sheet 7 take place. Basically, it can also initially be disc-shaped Body 1 'made of a metal strip or sheet 9 according to FIG. 4 punched out and then shaped in a device 10 in such a way that a blank 1 according to Figures 1 and 5 is formed.
  • the device 10 comprises an outer ring 11 and a lower stamping tool 12 and an upper stamping tool 13.
  • the two stamping tools 12 and 13 are expediently stamps with not shown in FIG. 6 Drives. They move inside a ring 14, the defines the outside diameter of the finished coin / medal.
  • the diameter of the disc-shaped body 1 ' is slightly less than the diameter of the ring 14.
  • the mutually facing surfaces 15 and 16 of the lower embossing tool and the upper embossing tool 13 have a contour 17 or 18 to achieve the desired deformation of the disc-shaped body 1 'on.
  • the contour 17 is mirror image of the contour 18 and includes for the core zone 3, 3 'in each case a flat depression 19 in the middle an annular elevation 20.
  • the elevation 20 is used to form the Intermediate zone 5, 5 '.
  • the ring-shaped elevation 20 in turn closes an annular recess 21 to the circumference of the lower or upper stamping tool 12 or rises again.
  • the wave profile of the Completed blank 1 is also based on the contour 17 and 18 of the two Embossing tools 12 and 13 can be clearly seen.
  • the reshaping of the Material on the sheet 7 or on the disc-shaped body 1 takes place further such that the transition from the intermediate zone 5, 5 'to the peripheral zone 4, 4 'on the one hand and to the core zone 3, 3' on the other hand gradually.
