Abstract

1463487 Extruding LUCAS ELECTRICAL Ltd 26 June 1974 [6 July 1973] 32446/73 Heading B3P A hollow cylindrical metal component 11 with one or more axially extending splines 14, on its external surface, such as a starter motor pinion, is produced by forcing a cylindrical billet into a die 18 using a punch 22 and a counterpunch 24, the die having axially extending ribs 19. The ribs 19 are recessed 21 behind their leading edge to reduce frictional drag on the metal. The counterpunch 24 is moved relative to the die 18 by the extruded material but sufficiently slowly to ensure complete formation of the splines between the die ribs 19. The force applied by the counterpunch is arranged to be substantially equal to the product of the yield stress of the billet and the area of the billet contacting the counterpunch.
