Abstract: A petalled tulip-shaped end of a transmission shaft is formed by a cold forging operation consisting of four stages. In a first stage a blank is formed to the approximate size of the component desired, one end of the blank being chamfered eventually to provide a stem. In the second forging operation the petals and stem of the component are roughed out by reverse and direct drawing respectively and a central recess having radial recesses branching off therefrom is formed in the end face of the blank remote from the stem. In the third forging operation the radial recesses and the lateral faces thereof are pushed in the direction of the stem to produce oblique ramps which are extended to provide surplus walls. The fourth and final forging operation involves a cutting off of these surplus walls.
