CA 2699318

The invention relates to a deep-drawing method and a corresponding deep- drawing device. The deep-drawing device has at least two projections (112) and at least two corresponding lamellar gaps (102) in a die (106), the width and positioning (Pi) of the lamellar gaps (102) being adjustable. Folding of a metal sheet (10) is brought about by closing the lamellar gaps (102). During the subsequent deep-drawing process, the projections (112) are lowered into corresponding recesses (103). Flat metal sheets (10) as well as previously corrugated metal sheets (10) can be folded and deep drawn by means of the deep-drawing device and the deep-drawing method.

La présente invention concerne un procédé d'emboutissage et un dispositif d'emboutissage correspondant. Le dispositif d'emboutissage présente au moins deux parties en saillie (112) et au moins deux interstices entre lamelles correspondants (102) dans un outil (106). La largeur et le positionnement (Pi) des interstices entre lamelles (102) sont réglables. La fermeture des interstices entre lamelles (102) provoque le pliage d'une tôle (10). Au cours du processus d'emboutissage consécutif, les parties en saillie (112) sont enfoncées dans des cavités correspondantes (103). Le dispositif d'emboutissage et le procédé d'emboutissage selon l'invention permettent de plier et d'emboutir à la fois des tôles planes (10) et des tôles préalablement ondulées (10).
