Abstract
The invention relates to a method for producing a hardened sheet metal section from a flat blank, wherein the flat blank is provided with collared holes that are collared and with two groove-like indentations which serve to support the sheet metal blank on a conveyor during heating treatment in an oven; subsequently, the blank is formed in a press tool into a sheet metal section by warm forming and where, if required, the formed indentations can be flattened; and thereafter the section is hardened while remaining clamped within the tool.
