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 present disadvantages of the prior art to eliminate, especially a coin minting press provide for the lowest possible height and has less play within the embossing drive.
  • this task is characterized by Features mentioned in the claim 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.
  • a shaft 3 is provided, which via a flywheel 4 and a belt transmission 5 from a motor 6 is driven.
  • a double cam 7 is placed on the shaft 3, which is part of a cam mechanism 8.
  • the cam mechanism 8 also has a rocker arm 9, which is provided with two arms which each have a cam roller 10 is attached, wherein the cam rollers 10 on the double cam 7 and feel them.
  • the rocker arm 9 is with a pressure plate 11 a knee joint 12 articulated.
  • the knee joint transmission 12 has an upper pressure plate 13 and a lower pressure tab 14, which together connected to the pressure plate 11 at one point and are articulated.
  • the upper pressure plate 13 is articulated at one end connected to the plunger 15 of the coin press 2, wherein the plunger 15 linear in a suitable plunger guide 16 is displaceable.
  • the other end of the lower pressure plate 14 is articulated connected to the machine frame 1.
  • the plunger in turn, is above the plunger 15 arranged plunger tool 17, in which the coin blanks from a feed drum 18 over a Feeding station 19 in a turret plate 20, 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 cam gear 8 and the Knee joint gear 12.
  • rocker arm 9 has on the knee joint transmission 8 facing end another bolt 23, with the pressure plate 11 on the pin 23 is articulated, which, as already mentioned, creates a connection to the knee joint transmission 12.
  • a tool clamping 27 for an embossing stamp 28 is provided on the plunger 15 .
  • Tappet 15 Based on the angle of rotation of the shaft 3 leads Tappet 15 in a range of approximately 60 ° crank angle up to 300 ° crank angle. In one area from approx. 300 ° crank angle to approx. 60 ° crank angle but the plunger 15 is not raised at all, so that during this time the plunger 15 with all tools attached to it stand still and during this time from the feed drum 18, the Feed station 19 and the turret plate 20 (see Fig. 1) a new coin blank in the minting station Minting press can be brought. Subsequently a new stamping process can take place.
  • Fig. 6 shows schematically an overall view of the used Gear combination from the cam gear 8 and the knee joint gear 12.
  • the dash-dotted lines illustrate the deflected position of the knee joint mechanism 8.
  • the double cam is graphically divided into three areas divided, with the solid line the Movement of the plunger 15 is shown upwards so if an embossing stroke is carried out during the Dashed line after the movement of the plunger 15 symbolized below, i.e. the return stroke, and the dash-dotted line for the area stands at which plunger 15 maintains its position, i.e. the area in which a minted coin is removed and a new coin blank is inserted into the embossing tool becomes.
  • the described Arrangement for example, the working height the coin minting press with a pressure of 300 t approx. 1900 mm to approx. 1400 mm.
