Abstract

1,124,802. Rolling. J. MARCOVITCH. 22 Sept., 1965 [30 Sept., 1964], No. 40312/65. Heading B3M. A cylindrical workpiece 20, Fig. 1, is profiled by passing it in a transverse direction between a convergent throat 10 formed by two rolls, 16, 18 rotated at different speeds in the same direction, and after the workpiece has been nipped in the throat the rolls are moved towards each other to reduce the pass. In a modification, the workpiece 26, Fig. 3, is passed through the throat 28, formed by a roller 24, and a hollow roller 22. In a further modification, the workpiece 30, Fig. 4, is an annulus, and is rolled between a roller 32 and a mandrel 34, the latter being in contact with a roller 36, circumferentially grooved at 38 to accommodate the workpiece. A roller (44), Figs. 5, 6 (not shown) can be moved to narrow the throat by an eccentric sleeve (48) actuatedby an hydraulic jack (52). The rolls may be replaced by members (62) and (68), Fig. 7 (not shown), member 62 being reciprocated by a power-driven rod (72), and the member (68) being moved to narrow the throat by hydraulic jacks (74). In a still further modification, a ring (84), Fig. 8 (not shown) is provided, which controls the outside diameter of the finished annular workpiece (86). In another modification, the outer diameter of annulus 90, Fig. 9 (not shown), is controlled by a ring (92) of cemented tungsten carbide inserted between inner and outer rollers (94), (96) with a mandrel (98) therebetween.
