Abstract (en)
[origin: WO2007006424A1] The invention proposes a method for the integral moulding of a flange (5) onto the end of a round or oval pipe (11) of thin-walled sheet metal. This method takes place in two stages. In a first stage, for the purpose of accumulating material, a sectionally circular or spiral-shaped bead (17) is moulded on by means of a pre-forming roller tool (9), comprising a combination of rollers (13 to 15) (Figure a). In a second stage, the moulded-on bead is compacted with the aid of a final-forming roller tool (18), comprising the rollers (19) and (20), to produce an at least partly solid flange (5) (Figure b).
