Abstract

A method for making wheel hubs of automobiles comprises the operations of - feeding a preheated cylindrical element to a horizontal forge having at least four consecutive stations to produce in sequence - a rough cylindrical blank 10, having a first circular cylindrical portion 10a connected to a second circular cylindrical stem portion 10b of diameter less than the first 10a, - a first semifinished piece 20 in which the first portion 10a of the rough cylindrical blank 10 is shaped in order to define a flange portion 20a adjacent to the stem portion 20c and a crown portion 20b opposite the stem portion 20c and having a bottom wall 27 provided with a central circular depression 29, - a second semifinished piece 30 in which the flange portion 20a of the first semifinished piece 20 is reduced in thickness and has a diameter larger than that of the first semifinished piece 20, and in which the central circular depression 32 of the crown portion 20b is deepened, and - a third semifinished piece 40 in which a central continuous hole 42 is produced by punching from the central circular depression 32 of the second semifinished piece 30. <IMAGE>
