Abstract

Die Erfindung bezieht sich auf eine Presseneinrichtung zum Herstellen maßhaltiger Presslinge aus im Wesentlichen pulverförmigem oder granulatförmigem Material mit

  • einem Rahmenwerk (70, 73), welches über eine untere Verbindungseinrichtung (71) mit einem unteren Pressengestellteil einer Presse adapterartig verbindbar ist,
  • einer Matrizenhalteplatte (5), die im Rahmenwerk (70, 73) angeordnet ist,
  • einem Grundkörper (0), der in dem Rahmenwerk (70, 73) angeordnet ist, wobei die Matrizenhalteplatte (5) und der Grundkörper (0) relativ zueinander verschiebbar in dem Rahmenwerk (70) angeordnet sind,
  • einer Vielzahl von Stempelträgern (75, 1, 2, 3, 4), von denen zumindest ein Teil am Rahmenwerk (70) relativ zur Matrizenhalteplatte (5) und relativ zum Grundkörper (0) in Pressrichtung verschiebbar zwischen diesen gelagert ist, und
  • Abstützeinrichtungen (12, 13, 14), welche die Stempelträger (2 - 4) in Pressendstellung relativ zum Grundkörper (0) abstützen.
The invention relates to a press device for producing dimensionally stable compacts of substantially powdery or granular material with
  • a framework (70, 73), which can be connected like a adapter via a lower connecting device (71) to a lower press frame part of a press,
  • a die holding plate (5) disposed in the framework (70, 73),
  • a base body (0) which is arranged in the framework (70, 73), wherein the die holding plate (5) and the base body (0) are arranged displaceably relative to one another in the framework (70),
  • a plurality of stamp carriers (75, 1, 2, 3, 4), of which at least a part on the framework (70) relative to the die holding plate (5) and relative to the base body (0) is mounted displaceably in the pressing direction between them, and
  • Supporting devices (12, 13, 14), which support the punch carrier (2 - 4) in Pressendstellung relative to the base body (0).

Um einen modularen Aufbau und eine verbesserte Abstützung zu ermöglichen, wird vorgeschlagen die Abstützeinrichtungen (12, 14) zwischen dem Grundkörper (0) und den Stempelträgern (2, 3 bzw.4) derart anzuordnen, dass zumindest eine der Abstützeinrichtungen (13, 14) durch eine andere der Abstützeinrichtungen (12 bzw. 13) gegenüber dem Grundkörper (0) abgestützt ist.

Figure imgaf001
In order to enable a modular construction and an improved support, it is proposed to arrange the supporting devices (12, 14) between the main body (0) and the stamp carriers (2, 3 or 4) such that at least one of the supporting devices (13, 14) by another of the support means (12 or 13) relative to the base body (0) is supported.
