Bending by drawing through a die, comprises forming a material by passing through at least one forming tool, where the material before forming is regionally heated to a temperature between the forming and the solidus temperature of the material, and the material after forming is regionally cooled such that the material properties are regionally and specifically adjusted. An independent claim is also included for a device for carrying out the above method, where the material for forming is guided through at least one forming tool by at least one transporting device (8), comprising at least one heating device (4) and at least one cooling device (7) so that the forming material is heated and cooled specifically and regionally before, during or after the forming process using the transportation speed. Verfahren zur Herstellung höchstfester, warm umgeformter Profilbauteile mittels Gleitziehbiegen. Erfindungsgemäß wird das umzuformende Material dabei vor dem Umformen bereichsweise gezielt auf Temperaturen zwischen der Umform- und der Solidustemperatur des Materials erwärmt. Nach der Umformung erfolgt eine gezielte bereichsweise Abkühlung des Materials, wodurch in Kombination die Materialeigenschaften, insbesondere Härte und Duktilität des Materials, gezielt eingestellt werden können. Weiterhin eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens, wobei das umzuformende Material mittels mindestens einer Transporteinrichtung durch ein Umformwerkzeug geführt und dabei umgeformt wird. Die Vorrichtung weist weiterhin mindestens eine Erwärmungseinrichtung und mindestens eine Abkühlungseinrichtung zur gezielten erfindungsgemäßen gezielten bereichsweisen Erwärmung bzw. Abkühlung des Materials auf.
