Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen eines ring- oder bogenförmigen Metallteils. Mit dem erfindungsgemäßen Verfahren lassen sich vergleichsweise große Metallteile mit hoher Stabilität und geringem Gewicht dadurch herstellen, daß ein Blech zu einem Ring (100) gebogen und die Enden des Bleches miteinander verbunden werden, daß in dem so gebildeten Blechring umlaufende Erhebungen bzw. Vertiefungen (105,106) mittels innerhalb und außerhalb des Bleches angeordneter Walzen (131..136) geprägt werden, deren zusammenwirkende Profile den zu erzeugenden Erhebungen bzw. Vertiefungen angepaßt sind, und daß beim Prägevorgang die Walzen gleichzeitig in radialer Richtung und parallel zur Achse des Blechringes so bewegt werden, daß der Blechring nur in radialer Richtung gestreckt oder gestaucht wird. The invention relates to a method for producing an annular or arcuate metal part. With the method according to the invention, comparatively large metal parts with high stability and low weight can be produced in that a sheet is bent into a ring (100) and the ends of the sheet are connected to one another by revolving elevations or depressions (105, 106 ) are embossed by means of rollers (131..136) arranged inside and outside the sheet, the interacting profiles of which are adapted to the elevations or depressions to be produced, and that during the embossing process the rollers are simultaneously moved in the radial direction and parallel to the axis of the sheet metal ring that the sheet metal ring is only stretched or compressed in the radial direction.
