Document Type and Number:
WIPO Patent Application WO/2011/007810
Kind Code:
A1
Abstract:
A bending device comprising: (a) a first manipulator for constituting a feeding means (22) which is disposed at a first position and feeds a hollow metallic material (25) in the longitudinal direction thereof, said metallic material (25) having a closed cross-section; (b) a second manipulator for supporting both a heating means (23) and a cooling means, the heating means (23) being disposed at a second position downstream of the first position in the feeding direction of the metallic material and heating a part of or the whole metallic material being fed, the cooling means being disposed at a third position downstream of the second position and cooling the portion of the metallic material being fed, said portion being that which is heated by the heating means; and (c) a third manipulator for constituting a second support means (24) which is disposed at a fourth position downstream of the third position and bends the metallic material being fed, the bending of metallic material being fed being performed in such a manner that, while supporting at least one part of the metallic material and moving in a two-dimensional or three-dimensional direction, the second support means (24) applies bending moment to the heated portion of the metallic material.
