Definitions

  • the invention relates to a coin press according to the preamble of claim 1.
  • both core and ring parts are to be fed to the coin stamping press by means of a turret plate.
  • the ring parts are usually at least compressed in the outer circumference before they are guided into the turret plate and thus into the coin press for joining.
  • These rings are first punched in a high-speed press in the follow-up tool and then fed to an upsetting machine. Care must be taken to ensure that the core hole - hole for the core - is not deformed.
  • European coin specification 0 151 204 B1 describes a coin stamping press with a ram-guided ejector. There is an ejector lever acting on the ejector rod, which is rotatably mounted in its end facing away from the tappet drive side on the piston rod of a pressure cylinder fixed to the frame. Ejector operation can therefore be interrupted for double strokes.
  • German Offenlegungsschrift DE 41 13 971 A1 describes a method and a device for producing ring-core coins, bi-metal coins, in which the ring part is compressed in its outer circumference before the core hole is punched out.
  • the punching tool requires a resilient hold-down device, so that measures are to be taken with the conversion according to the characterizing part of claim 1.
  • Claim 2 represents a preferred embodiment according to the invention.
  • the counter-holding device integrated for punching in the coin stamping press like the ram-controlled ejector operation for stamping, can be switched on or off as required.
  • the punching waste can be removed via a shaking channel.
  • the shaping, active tools are exchanged.
  • the reference number 1 shows a press frame of a coin stamping press in the tool and ejector area.
  • the plunger 2 moved in the press cycle acts via a push rod 3 on an ejector lever 4.
  • the ejector lever 4 is mounted with the end 11 facing away from the plunger articulation side 10 at 9 on the piston rod 12 of a pressure cylinder 5 fixed at 6.
  • the pivot point 9 forms a pivot bearing for the ejector lever 4 acted upon.
  • the position of the ejector lever 4 which is ineffective with respect to the ejector rod 8, as in FIGS. 2A, 2B shown is achieved by acting on the impression cylinder 5.
  • the ejector lever 4 of the ejector unit which is numbered 7 overall, acts in accordance with FIGS. 1A, 1B in the area 29 by means of pressure roller 13 via a pressure plate 14 onto the ejector rod 8.
  • a counter-holding device numbered 19 overall, is flanged to the press frame 1 and has a pressure cylinder with piston 20 and a pressure plate 21.
  • a pressure spring 22 is stretched out between the pressure plate 21 and the pressure cylinder.
  • a pressure piece 23, here a slotted sleeve is connected, which according to FIGS. 2A, 2B in the support area 29, instead of the pressure roller 13 on the ejector lever 4, the spring force of the compression spring 22 rests on the pressure plate 14.
  • the figures 1A, 1B show the ejector mode for an embossing tool 15 made of embossing stamp 16 and embossing ring 17 which is inserted into the coin minting press.
  • a punching tool 26 is inserted into the coin stamping press with a resilient hold-down 27 and a punching die 28. Further elements for the punching process are shown in FIGS. 3A to 3E explained.
  • Fig. 2A and 2B show the position in which the ejector operation is prevented.
  • the pressure roller 13 is lifted off the pressure plate 14 by acting on the pressure cylinder 5.
  • the counter-holding device 19 acts on the ejector rod 8 by means of a compression spring 22. This acts directly, or indirectly via an intermediate means such as a ring, or, as shown, via pressure pins on the hold-down device 27.
  • the significance of the hold-down device 27 and thus the optional switchover of the coin minting press to hole operation can be seen from the figures 3A to 3E.
  • the embossed piece previously compressed in the outer circumference has been moved into the processing stage by means of the feeder insert 33 or pocket of a turret plate, FIG. 3A. Due to the movement of the plunger 2, the punch die 28 is moved towards the resilient hold-down device 27 with the embossing piece, FIG. 3B.
  • the stamping piece is clamped between the punch die 28 and the hold-down device 27 acted upon by the counter-holding device 19.
  • the punch die 28 guides the stamping piece by displacing the hold-down device 27 against the punch punch 31, FIG. 3C.
  • the slug part is cut and separated from the ring part thus formed, FIG. 3D.
  • the ring part formed in this way is returned from the resilient hold-down device 27 out of the holder ring 30 into the feeder insert 33 by retracting the perforated die 28 as a result of the reverse tappet movement.
