Abstract

Die Erfindung betrifft eine Vorrichtung zum gesteuerten, dosierten Füllen von Metallpulver in Preßformen, mit der eine geringe Lage- und Formabweichung der Preßteile, ihre hohe Maßgenauigkeit und Gleichmäßigkeit der Materialdichte erzielt werden soll.
Erfindungsgemäß wird dazu der aus dem Werkzeugbereich beweg­ bare Füllschuh (1) mit einer Blendenverschlußeinrichtung in der Bodenplatte (2) versehen, die über eine Hebelanordnung erst geöffnet wird, wenn der Füllschuh (1) unmittelbar über dem Werkzeugfüllraum positioniert ist. Über eine Kurve (16) wird die Blendenverschlußeinrichtung gesteuert. Vor dem Wegbewegen des Füllschuhs (1) aus dem Werkzeugbereich wird die Blende geschlossen. Die wesentlichen Vorteile bestehen in der Vermeidung eines Schatteneffektes und dem Erhalt einer gleichmäßigen Pulverdichte beim Einfüllvorgang. The invention relates to a device for the controlled, metered filling of metal powder in molds, with which a small position and shape deviation of the pressed parts, their high dimensional accuracy and uniformity of the material density is to be achieved.
According to the invention, the movable filling shoe (1), which can be moved from the tool area, is provided with an aperture closure device in the base plate (2), which is only opened via a lever arrangement when the filling shoe (1) is positioned directly above the tool filling space. The shutter device is controlled via a curve (16). The cover is closed before the filling shoe (1) is moved away from the tool area. The main advantages are the avoidance of a shadow effect and the maintenance of a uniform powder density during the filling process.
