Abstract

Werkzeuganordnung zur Herstellung von ringförmigen Preßlingen mit Hilfe einer Rundläuferpresse, wobei die Rundläuferpresse eine drehend angetriebene Matrizenscheibe (10) aufweist mit Matrizenlöchem, in denen Matrizeneinsätze befestigt sind sowie zu den Matrizeneinsätzen ausgerichteten, mit diesen umlaufenden Ober- und Unterstempeln, die von Steuerabschnitten aufeinander zu oder voneinander fort bewegt werden und wobei die Unterstempel (14) eine zum Arbeitsende hin offene koaxiale Bohrung aufweisen, in der ein Mittelstift angeordnet ist, der von einem Querstift (34) relativ zur Matrizenscheibe axial festgelegt ist, wobei sich der Querstift (34) durch einen axialen Schlitz des Unterstempels erstreckt, wobei der Querstift (34) in einem Ring (36) festgelegt ist, der Teil einer Führungsbohrung für den Unterstempel (14) ist, die in einem radialen nach außen weisenden Vorsprung (24) der Matrizenscheibe (10) geformt ist, zwei klammerförmige Haltebügel auf gegenüberliegenden Seiten des Unterstempels (14) angeordnet sind, von denen ein längerer Schenkel (46) an der Unterseite des Ringes (36) anliegt und von denen ein kurzer zweiter Schenkel (48) den Vorsprung (24) übergreift, ein die Schenkel (44,48) verbindender Steg (50) über eine Schraubverbindung (52) mit dem Vorsprung(24) verbindbar ist, wobei die Haltebügel (44) und die Matrizenscheibe (10) so ausgebildet sind, daß bei einem Festziehen der Schraubverbindung (52) der lange Schenkel (44) axial gegen den Ring (36) in Richtung Matrize (16) gepreßt wird.

Figure 00000001
Tool arrangement for the production of ring-shaped compacts with the help of a rotary press, the rotary press having a rotatingly driven die plate (10) with die holes in which die inserts are fastened and aligned with the die inserts, with these rotating upper and lower punches, which from control sections towards or towards one another are moved away from each other and wherein the lower punches (14) have a coaxial bore open towards the end of work, in which a central pin is arranged, which is axially fixed by a cross pin (34) relative to the die plate, the cross pin (34) being defined by a extends axial slot of the lower punch, wherein the cross pin (34) is fixed in a ring (36) which is part of a guide bore for the lower punch (14), which is formed in a radially outward projection (24) of the die plate (10) is, two bracket-shaped brackets on opposite sides of the lower punch (14), of which a longer leg (46) rests on the underside of the ring (36) and of which a short second leg (48) engages over the projection (24), one of the legs (44, 48) connecting web (50) can be connected to the projection (24) via a screw connection (52), the retaining bracket (44) and the die plate (10) being designed such that when the screw connection (52) is tightened, the long leg (44 ) is pressed axially against the ring (36) in the direction of the die (16).
