Abstract

Vorgeschlagen wird ein Verfahren und eine Presse zum Warmformen und Preßhärten eines hochfesten Bauteils 7. Erfindungsgemäß befindet sich das untere Werkzeug 2 der Presse innerhalb eines Flüssigkeitsbades 5. Dabei können sowohl Teile 40, 41 der Formgeometrie als auch die gesamte Formgeometrie 4 unterhalb des Flüssigkeitsspiegels 50 liegen. Das warmzuformende und zu härtende Bauteil wird oberhalb des Flüssigkeitsspiegels 50 beispielsweise auf Halterungen 8 aufgelegt und beim Zufahren der Presse durch das obere Werkzeug 1 in das Flüssigkeitsbad 5 eingetaucht und in das untere Werkzeug 2 tiefgezogen. Dadurch werden die üblichen Haltezeiten stark verkürzt, was unter anderem einen Einsatz mechanischer Pressen ermöglicht.

According to the invention, the lower tool 2 of the press is located within a liquid bath 5. Both parts 40, 41 of the mold geometry and the entire mold geometry 4 may be below the liquid level 50 , The thermoforming and to be cured component is placed above the liquid level 50, for example, on brackets 8 and immersed in the liquid bath 5 when driving the press through the upper tool 1 and deep drawn into the lower mold 2. As a result, the usual holding times are greatly reduced, which allows, inter alia, a use of mechanical presses.
