Extension of geometric limits in drawing of stringer sheets.
In: Procedia Manufacturing, 15
Artikel, Bibliographie
Kurzbeschreibung (Abstract)
Stringer sheets are sheet metal parts with ribs. A process chain consisting of laser welding and subsequent forming allows the productive manufacturing of spatially curved stringer sheets. Compressive strains in concave curvatures can cause buckling of the stringers and define a process limit. We present a cam-actuated lateral support mechanism for the stringers to exceed current limits without reducing the productivity of the process. The experimental investigations show feasible stringer heights three times higher for supported stringers compared to non-supported stringers. The influence of this suppression of buckles on stiffness and springback is shown.
