Technical Field

[0001] The utility model belongs to the technical field of ball head pin production, and particularly relates to a one-step forming die for ball head pins. Background Art

[0002] The function of the ball head pin is to position and fasten components; it has two types: cylindrical and conical. The installation of the ball head pin generally adopts two methods: the press-fitting method or knocking it in with soft metal. The ball head pin is usually a conical, pointed or spire-shaped wooden or metal nail used to nail or fasten (wooden boards, tiles, soles, shoe uppers, furniture molds and components) or fill holes.

[0003] The existing ball head pins are generally formed by turning and milling on a machine tool or cold heading. Among them, during the cold heading production process, since the factory needs to produce ball head pins of different specifications and sizes, this results in the need for multiple sets of ball head pin molds. Moreover, during the replacement process, it is necessary to synchronously disassemble the cold heading part on the output end of the cold heading machine, which is time-consuming and laborious, and easily leads to an increase in working costs. Therefore, we have specifically designed a one-step forming die for ball head pins. Content of the Utility Model
