Abstract
Method for cold-forming hollow bodies of metal preferably tension-free steel whose hollow spaces for example of cylindrical shape of conical spherical cap or stepwise recess are obtained in bodies of any shape made of metal and especially steel by means of a spike characterized in that it gets into a die a pre-worked piece whose length is of equal or greater than the length of the finished piece and because the deformation of the pre-worked piece is carried out in a cold state, preferably expelling the material thereof freely towards the side or which rests against the side walls of the hole of the matrix by means of a correspondingly shaped spigot.
