Method for Manufacturing a Component

Abstract

A method for manufacturing a component from a hardenable aluminum alloy includes the steps of: heating a blank to a predefined temperature; shaping the heated blank into a semifinished product in a shaping tool; cooling the semifinished product during or following the shaping process; and shaping the cooled semifinished product into a component in a second shaping tool.

What is claimed is: 
     
         1 . A method for manufacturing a component from a hardenable aluminum alloy, the method comprising the steps of:
 heating a blank to a predetermined temperature;   forming the heated blank to a semi-finished product in a forming tool;   cooling the semi-finished product, wherein cooling is performed after forming or during forming; and   forming the cooled semi-finished product to a component in a second forming tool.   
     
     
         2 . The method as claimed in  claim 1 , wherein
 the heated blank in a preliminary forming step is pre-formed to the semi-finished product; and   the cooled and pre-formed semi-finished product is finally formed to a component in a final forming step.   
     
     
         3 . The method as claimed in  claim 1 , wherein
 the cooled semi-finished product prior to forming in the second forming tool is in a W state.   
     
     
         4 . The method as claimed in  claim 1 , wherein
 the component is hardened by a heat treatment.   
     
     
         5 . The method as claimed in  claim 1 , wherein
 trimming of the component, of the semi-finished product or of the blank is performed prior to hardening of the component.
