Abstract

879,450. Forging. APPEL PROCESS Ltd. Aug. 6, 1959 [Feb. 16, 1959], No. 26860/59. Class 83 (4). A mandrel 20 for use in a swaging machine has longitudinal grooves 15 of uniform width which increase gradually in depth. The mandrel is used for forming axial or spiral internal ribs such as rifling on tubular workpieces, such as gun barrels, which are fed incrementally over the mandrel from left to right and hammered by radially acting dies in a machine such as described in Specification 797,518. The mandrel body may be cylindrical or slightly tapered and the grooves vary in depth from left to right. An ungrooved portion 23 is used to condition the internal surface of the workpiece before the ribs are formed. Specification 829,122 also is referred to.
