Abstract

Vorgeschlagen wird ein Verfahren zur Herstellung eines mit mindestens einem Hohlraum versehenen Leichtmetall-Bauteils. Es soll eine verfahrenstechnische Möglichkeit geschaffen werden, bei hohlgegossenen Bauteilen aus Leichtmetall und insbesondere aus Aluminium zu einer Reduzierung der im Gefüge vorhandenen Hohlräume zu kommen, und so das Bauteil widerstandsfähiger gegenüber späteren mechanischen Beanspruchungen zu machen.Proposed is a method for producing a provided with at least one cavity light metal component. It should be created a procedural possibility to come in hollow-cast components made of light metal and aluminum in particular to reduce the cavities present in the structure, and so make the component resistant to later mechanical stresses.

Hierzu wird ein Verfahren zur Herstellung eines mit mindestens einem Hohlraum versehenen Leichtmetall-Bauteils vorgeschlagen, bei dem durch Sandgießen, Kokillengießen oder Druckgießen ein Gussteil erzeugt wird, und das Gussteil nach dem Erstarren und nach der Entfernung von Angüssen und Speisern auf eine Temperatur zwischen 350 °C und 500 °C erwärmt und bei dieser Temperatur in ein Gesenk eingelegt wird. In dem Gesenk erfolgt durch mindestens einen Schmiedeprozess eine Knetung des metallischen Gefüges unter zumindest partieller Umformung des Gussteils.For this purpose, a method for producing a light metal component provided with at least one cavity is proposed in which a casting is produced by sand casting, die casting or die casting, and the casting after solidification and after the removal of sprues and feeders to a temperature between 350 ° C and 500 ° C is heated and placed in a die at this temperature. In the die by at least one forging process, a kneading of the metallic structure with at least partial deformation of the casting.
