Abstract

1,138,521. Rolling; flow of metal produced by rotary rubbing tools; forging. FAIREY CO. Ltd. 26 Jan., 1966 [28 Oct., 1964], No. 44032/64. Addition to 884,980. Headings B3H, B3M and B3V. An integral helical fin is formed on the surface of a workpiece 33 by means of freely rotatable or driven rollers 20 mounted on a rotating tool 10, Fig. 2, the rollers softening the workpiece by their repeated impacts. Each roller is formed by a number of separate or integral parallel discs 15 of increasing diameter. The workpiece is fed at a slight angle to the axis of rotation 13 of the tool to permit a helical fin to be progressively formed on the workpiece. Guide plates 25 are located between the rollers, the plates extending in the same planes as the discs of the rollers with a plate corresponding to each disc. A milling cutter may be provided on the tool for finishing the edge of the fin. The tool can be arranged to surround a workpiece, the rollers in this case extending radially inwards towards the axis of rotation of the tool. The rollers may be positively rotated by gearing either in the same or the opposite direction of rotation as the tool and a friction brake may be provided for each roller to produce frictional retardation of the discs. The disc of each roller closest to the tool body can be made integral with the body and integral with the adjacent guide plates 25.
