[0002] As a connecting and fixing part, ball pins are mostly used in automobile suspensions or other parts. Ball pins are generally divided into two integrally formed parts, namely the ball head and the handle. A single-sided ball pin is one in which the handle is placed on one side of the ball head, and a double-sided ball pin is one in which the handle is placed on both sides of the ball head. Since the diameter of the ball head is generally larger than the diameter of the handle, the diameter of the ball head is often used as the standard when selecting the blank, and then the blank is processed and formed by removing the material, followed by forging strengthening, rough blank shaping, heat treatment and other steps. Such a processing technology not only has complicated steps, but also greatly wastes raw materials. Based on this, it is necessary to improve the existing process and redesign the production line according to the improved process to ensure production efficiency. Summary of the invention
