Description
Schleudertrommel Die Erfindung bezieht sich auf eine Schleudertrommel, die aus einem einzigen Stück durch Tiefziehen mit einwärts gebördeltem oberem Mantelrand geformt ist, und sie besteht darin, daß die Trommel aus Aluminiumblech besteht. Dabei können der Mantel und die Decke der Schleudertrommel eine in an sich bekannter Weise durch Strecken erreichte geringere Wandstärke als der Boden aufweisen.Centrifugal drum The invention relates to a centrifugal drum, made from a single piece by deep drawing with the upper edge of the jacket beaded inwards is shaped, and it consists in that the drum is made of aluminum sheet. The jacket and the ceiling of the centrifugal drum can be a known per se Way achieved by stretching have a thinner wall thickness than the floor.
Solche Schleudertrommeln, für die andere betriebliche Verhältnisse gelten als für die sonstigen Behälter, die bisher schon im ganzen aus Aluminium hergestellt wurden, wie z. B. Milchkannen, können in Steilboden- oder au-eh in Flachbodenbauart ausgeführt werden.Such centrifugal drums, for other operational conditions are considered to be the case for the other containers that have hitherto been made entirely of aluminum were made such. B. milk cans, can be in steep-bottom or flat-bottom design are executed.
Im ersteren Fall erfolgt der übergang vom Mantel zu dem unter einem Winkel von etwa 60' gegen die Horizontale geneigten Boden mit einer verhältnismäßig großen Ausrundung, der übergang vom Mantel zum einwärts gebördelten oberen Mantelrand dagegen mit einer kleinen Ausrundung von z. B. 3 mm. Dabei nimmt die Wandstärke entsprechend der Verdrängung des Werkstoffes beim Tiefziehen von unten nach oben etwas zu.In the former case, the transition from the jacket to the bottom, which is inclined at an angle of about 60 ' to the horizontal, is made with a relatively large fillet. B. 3 mm. The wall thickness increases somewhat from bottom to top in accordance with the displacement of the material during deep drawing.
Im letzteren Fall haben dagegen beide übergänge vom Mantel sowohl zu dem waagerechten Boden als auch zur Decke eine kleine Ausrundung. Ferner ist hierbei die Wandstärke des Mantels und der Decke in gleicher Weise gegenüber der Wandstärke des Bodens zu verringern. Das läßt sich durch einen besonderen Streckvorgang zwischen dem Tiefziehen und dem Umbördeln oder Kümpeln erreichen.In the latter case, however, both have transitions from the jacket to the horizontal floor as well as to the ceiling a small rounding. Furthermore is here the wall thickness of the jacket and the ceiling in the same way compared to the To reduce the wall thickness of the floor. This can be done through a special stretching process between deep drawing and flanging or dishing.
Als Werkstoff eignet sich für eine solche Trommelherstellung eine Leichtmetall-Legierung mit einer Streckgrenze von etwa 40 bis 45 kg7MM2. Dadurch werden die Schleudertrommeln im Verhältnis der spezifischen Gewichte dieser Legierung zu dem für die Schleudertrommeln von Zuckerzentrifugen bisher ausschließlich verwendeten Stahl leichter. Mit dem infolgedessen um etwa 30% geringeren Schwungmoment wird zugleich ein entsprechend geringerer Kraftbedarf notwendig.A suitable material for such a drum production is Light metal alloy with a yield strength of around 40 to 45 kg7MM2. Through this the centrifugal drums are in proportion to the specific weights of this alloy to the one previously used exclusively for the spinning drums of sugar centrifuges Steel lighter. The moment of inertia is reduced by around 30% as a result at the same time a correspondingly lower power requirement is necessary.
