Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing molds, and more particularly to an upsetting mold for consumer electronic fasteners. Background Art

[0002] In the field of consumer electronics, fasteners are important components for connecting and fixing various small parts, circuit boards, housings and other components. As electronic products develop towards being lighter, thinner and shorter, the requirements for fasteners are becoming higher and higher. They are not only required to have sufficient mechanical strength, but also to have precise dimensions and good surface quality. The upsetting die is a tool used for metal plastic processing. It applies pressure to cause the metal material to undergo plastic deformation, thereby obtaining fasteners of the desired shape and size.

[0003] The upsetting process can ensure that the fasteners are more secure when fixed with solder, but the traditional upsetting operation requires manual filling, that is, the operator needs to manually place each fastener into the processing position, or use a robot for automatic filling, and only one fastener can be placed at a time. The filling process is not only time-consuming but also extremely inefficient, because the operator must place the fasteners one by one, which limits the efficiency of processing and production. In addition, for small fasteners, due to their light size and weight, they are prone to position deviation and other problems during the processing process, which not only affects the processing quality and increases the scrap rate, but may also damage the mold, accelerate mold wear, reduce the service life of the mold, and increase production costs. Therefore, it is necessary to propose a new solution to solve the problem of poor processing efficiency and easy damage to the mold during upsetting of fasteners. Utility Model Content
