Description
Verfahren zum satzweisen Gießen von Bremsklötzen Es ist bekannt, mehrere Bremsklötze zugleich zu gießen. Die Erfindung besteht darin, daß die Bremsklötze durch Schleuderguß, in einer Ringform hergestellt werden. Da sich hierbei die Bremsflächen an der Stelle der geringsten Zentrifugalkraftwirkung bilden und außerdem langsamer als die äußeren Randteile erstarren, zeigen sie keine harten Stel# len. Hart wird nur der verhältnismäßig rasch erstarrende Rücken des Bremsklotzes, welcher aber ohne jede Bearbeitung vermöge entsprechender Gestaltung im Klotzschuh festgehalten werden kann. Die Bremsflächen werden deshalb ein durchaus gleichmäßiges und verhältnismäßig leichteres Korn erhalten, welches gerade die Eigenschaften aufweist, die man von einem guten Bremsklotz verlangt.Method for batch casting of brake pads It is known several Pour brake pads at the same time. The invention consists in that the brake pads by centrifugal casting, in a ring shape. Since this is where the braking surfaces form at the point of least centrifugal force and also more slowly when the outer edge parts solidify, they show no hard spots. Hard only the back of the brake block, which solidifies relatively quickly, but which one held in the block shoe without any processing by virtue of the appropriate design can be. The braking surfaces are therefore quite even and proportionate get lighter grain, which just has the properties that one of a good brake pad required.
Das Gießen kann in Formen mit senkrechter oder waagerechter Achse geschehen, die für jedesmaligen Gebrauch aus dem üblichen Sand- und Lehmmaterial hergestellt oder auch für dauernden Gebrauch als Kokillen ausgebildet sein können, welche nach Bedarf mit Kühlung oder Vorwärmung sich ausrüsten lassen. Auch in diesem Fall werden, auch wenn keine unmittelbare Abschreckung durch die Kokillenwandung erfolgt, die Bremsklötze an ihrer Außenseite härter sein als auf der inneren, als Bremsfläche wirkenden Seite.The casting can be done in forms with a vertical or horizontal axis happen, for each use from the usual sand and clay material manufactured or designed for permanent use as molds, which can be equipped with cooling or preheating as required. Also in this Fall, even if there is no immediate deterrent from the mold wall takes place, the brake pads are harder on their outside than on the inside Braking surface acting side.
In der Zeichnung ist die Erfindung an einem senkrechten Querschnitt durch eine Kokille mit senkrechter Achse schematisch erläutert.In the drawing, the invention is in a vertical cross section explained schematically by a mold with a vertical axis.
Es bezeichnen i die Bremsklötze, welche satzweise in fortlaufender Reihe durch Schleudern des Metalls gegen den Umfang der Kokille 2 entstehen. Die Zwischenlagen 3 bestehen zweckmäßig aus abschreckend wirkendem Material und ermöglichen so eine scharfe Trennung der einzelnen Bremsklötze i, welche mit einer Einlage q. zusammengegossen werden können, die eine spätere Weiterverarbeitung oder Benutzung ermöglicht.I denote the brake pads, which are consecutive in a sentence Series are created by hurling the metal against the circumference of the mold 2. the Intermediate layers 3 are expediently made of a deterrent material and allow such a sharp separation of the individual brake pads i, which with an insert q. can be poured together for later processing or use enables.
