| The invention relates to a cold forming method for producing ball journals comprising a ball region, a conical region and a threaded region for installation in ball-and-socket joints. According to said method, a ball journal blank (1) comprising a formed conical region (3) and cylindrical regions for the thread (2) and ball (5) are produced from a rod-shaped semi-finished bar material by extrusion. After the extrusion step, the ball region is subsequently formed by means of a rolling method in an additional production stage. At the same time, the threaded region can be given its final form. The production of the ball journal is thus achieved exclusively by cold forming and permits a significant increase in the production quantity per time unit in comparison with known methods in prior art. More economical types of steel can thus be used, as the cold forming method guarantees the sufficient durability of the ball journal. | ||||||
