A method for hot-forming and hardening a sheet-metal component with flanges in a cooled forming tool and an apparatus for carrying out the method are disclosed. A heated sheet-metal blank is inserted in a forming tool having a hollow form, with the sheet-metal blank projecting over the hollow form in marginal regions. The sheet-metal component formed from the sheet-metal blank is hardening of in the hollow form. A first flange having an X-bending axis is formed in a first marginal region with an auxiliary tool, and a second flange having a Y-bending axis is formed in a second marginal region with the auxiliary tool. The auxiliary tool has a plurality of dies, and the X- and Y-bending axes are not collinear and may be orthogonal to each other. Bending axes with a substantially perpendicular mutual orientation can be produced simultaneously in a single forming step.
