Abstract
1,232,494. Making profiled tubes and beams; shearing angular bending and winding. SIDERURGICA OCCIDENTAL C.A. 3 Sept., 1969 [29 Nov., 1968], No. 56671/68. Headings B3A, B3E and B3W. [Also in Division E1] A process of cold forming structural steel shapes having transverse sections of enclosed form comprises passing a round welded steel tube through successive forming rollers to progressively deform the tube by forcing its side portions together, forming a web of parallel touching thicknesses of the wall of said tube while flattening its top and bottom surfaces to form flanges above and below said web. In forming the steel tube a coil 30 of hot or cold rolled steel is passed through a slitter 33 and wound into slit coils 35 by a winder 36 (Fig. 1). The slit coils are joined and wound on a larger reel and the strip then formed into a tube and longitudinally welded. Sets of vertically mounted rollers 61-68 and co-operating horizontally mounted rollers 71-78 (Figs. 9 to 16, not shown) progressively deform the round tube into an H-beam 59 (Fig. 7) the tube weld 48 being situated in the centre of the web 60. The beam is cut into lengths by a shearing device comprising a pair of clamps 86, 87 (Fig. 17) and a shear blade 88 (Fig. 18). A channel section beam (Fig. 21) can also be formed by this process.
