Abstract
A hot-forming line for producing hot-formed and press-quenched sheet-steel products includes a temperature control station for heating at least one sheet-metal blank, a hot-forming and press-quenching tool for hot forming and press quenching the heated sheet-metal blank and at least one blank gripper for gripping and transferring the sheet-metal blank before and/or after hot forming and press quenching. The at least one blank gripper forms at least one contact region with the sheet-metal blank during the gripping of the sheet-metal blank. Also, the at least one blank gripper is configured to cool the sheet-metal blank in the at least one contact region during gripping and transfer of the sheet-metal blank before hot forming and press quenching and/or heat the sheet-metal blank in the at least one contact region during gripping and transfer after hot forming and press quenching.
