Abstract:
A method for producing a shaped part from an aluminum sheet that includes an aluminum alloy, in particular an aluminum alloy of the 5000 series. The method includes introducing at least one aluminum sheet in a forming tool and cold-forming the aluminum sheet in the forming tool, and heating the cold-formed aluminum sheet at least once at least in some regions and at least once further metal forming the aluminum sheet. In order to create advantageous conditions for the method, it is proposed for the heated aluminum sheet to be subjected to the further metal forming step even before a temperature has been reached which the aluminum sheet has during the cold forming thereof.
