Abstract

The stud blank has on one end a hollow sleeve (1), the other end being solid. This is held a fixed die (3) and a mandrel (2) inserted into the hollow end. A moving die (4) fits over the mandrel and outer diameter of the stud and a pusher sleeve (10) is inserted into the annular space. The pusher and moving die close the gap and the stud is deformed to form a collar (8) against two annular recesses in each die. A second collar is formed (9) by interposing an intermediate ring (13) between the dies and repeating the cycle, this ring being in three equal sections.
