Claims13
A method of forming a workpiece from a flat metal blank in a forming die, comprising the steps of:
- providing a forming die with at least one cavity;
- providing at least one blankholder for fixing the flat metal blank to the at least one cavity during the forming;
- heating the flat metal blank to a solution heat treatment temperature specific to the flat metal blank;
- disposing the heated flat metal blank in the forming die while the forming die is set to the solution heat treatment temperature specific to the flat metal blank;
- and
- forming the workpiece from the flat metal blank at the solution heat treatment temperature, while selecting a pressure of the at least one blankholder onto the flat metal blank to enable the material of the flat metal blank to be drawn from a region below the at least one blankholder into the at least one cavity, and/or
- while actively pushing the flat metal blank above a lower tool frame into the at least one cavity.
