Abstract
Official abstract text for this publication.
The present disclosure relates to a method for producing a shaped sheet metal component from a billet by means of U O forming, wherein firstly a preform is created by the U-forming and then a final shaping is performed by the O forming to give a final form.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process of producing a shaped sheet metal component from a billet by U-O forming, the process comprising: providing a planar billet, shaping the billet on a shaping tool with a first curvature about a first spatial axis, driving a shaping press into the billet that has been shaped with the first curvature, the shaping press creating a second curvature of the billet about a second spatial axis, which is substantially orthogonal with respect to the first spatial axis, and simultaneously producing a third curvature about a third spatial axis, the third spatial axis being substantially orthogonal with respect to the first spatial axis and to the second spatial axis, wherein said shaping and driving create a U-preform, the driving-in of the shaping press creating the first curvature on the U-preform, inserting a filling body into the U-preform, and removing the filling body from the U-preform in a perpendicular direction relative to a longitudinal direction of the U-preform, and the removing of the filling body elastically deforming the U-preform.
