Abstract (en)

Production of cold-formed components made of a hardenable aluminum material comprises producing an aluminum strip or sheet, positioning the strip or sheet, heat treating, and cold forming. Cold forming is carried out shortly after heat treatment. Preferred Process: The heat treatment is carried out by calcining and quenching the aluminum strip or sheet. The aluminum strip or sheet has a width of up to 1000 mm.

Abstract (de)

Die Erfindung betrifft ein Verfahren zum Herstellen von kaltumgeformten Bauteilen (12) aus einem aushärtbarem Aluminiumwerkstoff. Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung von kaltumgeformten Bauteilen aus aushärtbaren Aluminiumwerkstoffen anzugeben, bei dem die Verarbeitbarkeit des verwendeten Aluminiumbandes unabhängig von der Lagerzeit ist. Die Aufgabe wird durch ein Verfahren zum Herstellen von kaltumgeformten Bauteilen aus einem aushärtbarem Aluminiumwerkstoff gelöst, welches folgende Schritte umfaßt: Erzeugen eines Aluminiumbandes (1) oder -blech, Zwischenlagern des Aluminiumbandes (1) oder -blech, Wärmebehandeln des Aluminiumbandes (1) oder -blech, Kaltumformen des Aluminiumbandes (1) oder -blech, wobei die Wärmebehandlung in zeitlicher Nähe des Kaltumformens erfolgt. <IMAGE>
