  • Each stamp consists of a pressure piece and an or several pressure rods, preferably round in cross section, which are attached to the associated head plate.
  • the Push rods conveniently have at both ends Threaded shafts of small diameter, with which they on the one hand be screwed into the pressure piece and on the other hand through the head plate inserted and fastened with a nut become.
  • the push rods are, apart from the different lengths, all the same. You will be on Pressure piece attached in its centroid. At Larger thrust pieces can use multiple push rods become. To align the pressure pieces, it is sufficient to Fastening holes in the correct place of the Attach headstock, which in particular with computer-aided processing machines very rational and can be performed with high accuracy.
  • the push rods of the top plate which is arranged higher penetrate the underlying head plates, e.g. at three Stamp groups enforce those on the top headstock attached push rods the other two head plates and the push rods of the middle plate push through bottom plate.
  • the push rods are not intended to Management of the lower head plates in vertical Direction. This is done at the bottom Head plates attached guide rods, which the assigned and at least the top plate arranged above it enforce and have stops that the distances of the Limit head plates.
  • These attacks are useful formed as heads or as cross pieces, which on the lower End faces of the guide rods are screwed on.
  • the pressure pieces related to the movement of the Neighbor pressure pieces dimensioned so high that they in each Standing with their side faces touching and can lead each other.
  • the arrangement is preferably made so that the Stamps attached to the top headstock and the feed and shaking forces from the stamp bear immediately noticed, penetrate deeply into the molding material.
  • spacer strips are attached to the lower head plates, which, in the final position of the molding process, corresponds to the put on top plate and the forces transmitted as best as possible.
  • Preferably several intersecting spacer bars are provided, which are arranged are that the forces are evenly on the underlying plates and the arranged on these Transfer stamp.
  • this is achieved in that the head plates are penetrated by guide rods, which on have a stop at the bottom and at the top of a Support plate are attached and that can be operated with compressed air Bellows are provided to support the support plate raise the top head plate so that all head plates are up can be contracted for mutual investment.
  • This Relative position also of the pressure pieces is indicated by a corresponding compressed air control arrangement at the beginning of Lowering movement brought about. When the end position is reached the bellows are then quickly vented, so that the individual stamp groups in order from the molding be lifted off.
  • FIGS. 1 and 2 all occurring stamp shapes moved into one level, so that 3 does not match the bore pattern.
  • FIG. 1 shows a section of an upper head plate 1 which means a deeply penetrating large pressure piece 2 a push rod 3 is attached.
  • the upper part of the Pressure piece 2 is approximately cube-shaped and adjoins it down to a four-sided wedge shape, the lower End face has slightly rounded edges.
  • the push rod 3 has a round cross-section like the rest and on both Ends a molded threaded shaft.
