Abstract

1. Process for producing axles, especially of railway rolling stock, by forging in a mould (9, 10, 13, 14) a heted blank (8) of a diameter less than the largest diameter of the axle to be produced, characterised in that at least some of the blank (8) is heated to a temperature of between 1 100 degrees and 1 300 degrees C, preferably near 1 260 degrees C, in that the axle has two spindles (f1 , f2 ), and in that forging includes a simultaneous operation of upsetting the central parts (c, pc, pd) of the axle and extruding at least one of the two spindles (f1 , f2 ), this simultaneous operation being carried out as a result of a movement towards the centre of the axle of at least one ring (13, 14) forming part of the mould, this movement being produced by means of a single press stroke.
