Definitions

  • the invention relates to a coin minting press, with a Machine frame, an embossing drive for ram and Embossing stamp, an ejector stamp, against the the embossing stamp with the blank in between can be pressed and is partially yieldable, a drive for the ejector movement of the ejector die and one device for feeding each Embossing blank and for removing the finished part.
  • Such a coin stamping press is known from EP-A-0 101 590 known.
  • the coin drive is used for the coin drive by means of a crankshaft known per se via a central bearing driven triangular lever, which with its rear swing arm bearing on a handlebar and over this on the rack side and with its front Swing arm bearing via a push rod on the ram is articulated.
  • This vibration system is designed that pivots and pivot points in their positions to each other one for the push rod at its pivot point on the pestle at the time of driving through the rear Dead center at least approximate circular Enable movement.
  • the arrangement mentioned makes it possible to perform the linear movement to control the plunger so that sufficient Time remains between two embossing processes to take a minted coin out of the minting tool and insert a new blank coin.
  • a disadvantage of the known coin minting press is that that the described embossing drive is proportional takes up a lot of space, especially when he's in Presses should be used, which pressures of more than 200 t to exert on the blank coin. This one Forces also have to act on the embossing drive individual components of the same dimensioned accordingly stable be so that the individual components are relative large must be provided.
  • Another disadvantage of the well-known coin minting press is the relatively large game within the embossing drive, that from the multitude of joints used results.
  • the present invention is therefore based on the object the disadvantages of the prior art described Eliminate technology, especially a coin minting press provide for the lowest possible height and less play within the embossing drive having.
  • this task is characterized by Part of claim 1 mentioned features solved.
  • Another advantage of the coin minting press according to the invention lies in reducing the play of the embossing drive, because it has fewer joints, than this in known coin minting presses Case, so that the overall game, which is composed of the game in the individual joints, is reduced. This reduction in play is particularly noticeable with frequent load changes, such as this fast-running coin minting presses is positive noticeable.
  • an eccentric shaft 3 is provided for a coin stamping press 2, which via a flywheel 4 and a belt transmission 5 is driven by a motor 6.
  • a connecting rod 7 is driven by the eccentric shaft 3, which is part of a coupling ratchet mechanism 8.
  • the Connecting rod 7 is largely parallel to the embossing plane Coin (not shown) arranged.
  • the coupling ratchet mechanism 8 also has a support device, those in the present embodiment is designed as a tab 9.
  • the tab 9 is articulated at one end with the connecting rod 7 and articulated at its other end with the machine frame 1 connected.
  • the connecting rod 7 is off-center, more precisely along its longitudinal axis is shifted off-center to the Eccentric shaft 3 placed, the tab 9 opposite end of the connecting rod 7 with a pressure plate 10 which is a connection between the Coupling ratchet mechanism 8 and a knee joint mechanism 11 manufactures.
  • the knee joint transmission 11 has an upper pressure plate 12 and a lower pressure tab 13, which together connected to the pressure plate 10 at one point and are articulated.
  • the upper pressure plate 12 is articulated at one end connected to the plunger 14 of the coin press 2, wherein the plunger 14 linear in a suitable plunger guide 15 is displaceable.
  • the other end of the lower pressure plate 13 is articulated connected to the machine frame 1.
  • the plunger in turn, is located above the plunger 14 arranged plunger tool 16, in which the coin blanks from a feed drum 17 via a Feeding station 18 in a turret plate 19, which is provided with a stepping gear become.
  • Figures 2 to 4 show in an enlarged view that already described in connection with FIG. 1 Combination of the detent gear 8 and the knee joint mechanism 11.
  • Another bolt 23 is used to connect the Bolt 21 opposite end of the upper pressure plate 12th with the plunger 14, which is guided in the plunger guide 15 is.
  • a tool clamp 24 for an embossing stamp 25 is provided on the plunger 14 .
  • the plunger 14 Based on the angle of rotation of the eccentric shaft 3 leads the plunger 14 in a range of approximately 40 ° crank angle up to approx. 320 ° crank angle.
  • crank angle of the tappet 14 is only very slight raised so that during this time the plunger 14 with all the tools attached to it essentially stands still and during this time from the Feed drum 17, the feed station 18 and the turret 19 (see Fig. 1) a new coin blank in the minting station of the coin minting press are brought can. A new stamping process can then take place.
  • Fig. 6 shows schematically the combination used the Koppelrastgetriebes 8 with the knee joint transmission 11.
  • Point 30 should be emphasized in particular, namely the connection point or the joint between the pressure plate 10 and the connecting rod 7.
  • Another advantage resulting from the described Construction results in a reduction in eccentricity the eccentric shaft 3, for example from 40 mm to 20 mm, so that between the motor 1 and the Eccentric shaft 3 compared to the prior art smaller clutch can be installed, which makes reduce the manufacturing cost of the coin press 2.
  • the stroke of the coin minting press described 2 nevertheless largely corresponds to the stroke of known coin minting presses.
  • the support device executed as a tab 9.
  • a support device 9 to provide, for example a Thrust joint.
