The invention relates to a method for hot forming semi-finished products made of steel. The semi-finished product (1) is heated to a forming temperature, transported to a forming tool, and hot formed, hardened, or press-hardened in the forming tool. The aim of the invention is to provide a method for hot forming the semi-finished products made of steel, wherein even extremely thin-walled panels can be transported at forming temperatures without any problems and fed to the forming tool flawlessly without limiting the degree of deformation of the semi-finished product (1). This is achieved in that at least one rigidity-increasing structure (2, 3) is at least introduced into the semi-finished product (1) prior to the hot forming, hardening, or press-hardening process, and the structure (2, 3) which increases the rigidity of the semi-finished product is completely or at least partly arranged in the trimming region (4) of the semi-finished product (1). |
