A method for producing metal sheets having a desired configuration and additional features with the use of super load ical deformation

摘要

A method for producing metal sheets (10) with a desired configuration by successive expanded form of sheet metal blanks (20), in the case of a transformation temperature for the blanks (20), with the fluid pressure against a durable forming tool and to form of an additional feature (16) on the metal sheet (20), comprising the steps of:Providing a template (40) for the attribute (16), wherein the template (40) not thicker than the sheet metal (20) is,Arrangement of the template (40) either (a) on the selected section of the sheet blank (20) or (b) on the forming tool (22, 24),superplastic forming of the sheet blank (20) in the case of the transformation temperature against the shaping tool (22, 24) and the template (40) is arranged, in order to the metal sheet (10) with the desired configuration, including the feature (16) to form,Removal of the metal sheet (10) of the tool (22, 24), and, when the screen (40) at the beginning on the tool (22, 24) has been arranged,Removal of the template (40) from the tool (22, 24), after the metal sheet (10) with the feature (16) has been formed,characterized in thatthe template (40) is a sprayed-on layer, which comprises a solid lubricant.
