A hot forming tool includes a top tool and a bottom tool, both of which can be moved towards each other. When the hot forming tool is closed, a mold cavity is formed between the top tool and the bottom tool, with the top tool and/or the bottom tool being divided into at least two segments. The hot forming tool has one segment designed as a heating segment. The heating segment includes a compensating element on a side thereof opposite the mold cavity, to compensate for a thermal expansion of the heating segment in the press stroke direction.

Resiliently mounted, segmented hot forming tool and method for producing a hot formed and press-hardened steel component having a sharply defined transition region

The present invention relates to a press-forming tool having a top die and a bottom die, which can be moved toward one another, forming a forming cavity between the top die and the bottom die when the press-forming tool is closed, wherein a die clamping plate is arranged on a press ram and/or on a press table, wherein a top die or bottom die, which can be moved relative to the die clamping plate, is supported on said plate while incorporating at least one resilient adjusting element.
