Abstract

Structural car body components made of advanced-high-strength steels (AHSS) offer a high potential for lightweight design, while meeting increased requirements regarding crash performance simultaneously. However, manufacturing the dedicated parts using conventional deep-drawing processes often results in a high amount of shape deviation after removing the part from the tool. A concept for reducing this springback was developed at the IFU Stuttgart. The approach consists in a modification of the draw bending process by alternating the blank draw-in.

Gesteigerte Vorhersagegenauigkeit bei der Rückfederungsberechnung mehrstufiger Blechumformverfahren

Abstract

Karosseriebauteile aus ultrahochfesten Stahlblechen bieten ein hohes Leichtbaupotential bei gleichzeitiger Erfüllung steigender Crashanforderungen. Die Herstellung solcher Bauteile mittels konventioneller Tiefziehverfahren führtrückfederungsbedingt zu erhöhten Form- und Maßabweichungen.
