Abstract

Forging method, particularly cold, of an outline for a written end of a ball pen, consisting of placing a blank piece of an appropriate ductile material in a hollow die that has a fixed counterpoint and an opening at its bottom, delimiting the walls of this matrix at the same time the outer wall of the ball housing and the inner wall of the cup that prefigures this housing and at least a part of its supply channel; then penetrate into the die, up to the vicinity of the end of the counterpunch, a coaxial punch to the die, causing the relative movement of the punch and the die to flow the material of the blank, which makes it, on the one hand, penetrating by intrusion into the narrow space that converges between the walls of the matrix and the counterpunch, in such a way that it completely fills it and adapts to it closely in its forms, and making it, on the other hand, flow backwards by stretching length of the punch wall.
