Abstract

Die Erfindung bezieht sich auf eine Füllvorrichtung für axiale Pulverpressen mit einer Fülleinrichtung (12), die eine Füllerantriebsplatte (17), einen insbesondere pressenseitig sitzenden Füllschuh (15) und eine Pulver-Zuführungseinrichtung (13, 14) aufweist. Die Fülleinrichtung (12) ist mittels eines Verstellantriebs (16) auf einer Füllerplatte (6) vor- und zurück verschiebbar und der Füllschuh (15) ist in einer Füllstellung auf die Füllerplatte (6) bzw. eine darin sitzende Matrizenoberfläche drückbar. Erfindungsgemäß ist der Füllschuh (15) an die Füllerantriebsplatte (12) nur lose angekoppelt. Dadurch kann der Füllschuh mit einer kontrollierten und gleichmäßigen Verstellkraft beaufschlagt werden.
