[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Application scenarios: In the field of electronic manufacturing, silver-plated wires are often used to interconnect different circuits on a substrate. Traditionally, the forming process of silver-plated wires mainly relies on manual operation. This method is not only time-consuming and labor-intensive, but also results in low consistency and matching of finished products, leading to low production efficiency and high scrap rate. Especially for substrates with discontinuous and small-pitch characteristics, it is more difficult to manually form silver-plated wires, which further increases production costs and raw material waste.

[0024] like Figs. 1-2 The forming fixture shown includes a bench drill with a drill bit lock and a lower base. The bench drill controls the drill bit lock to press down via a handle. The fixture is characterized by further comprising:

[0025] The upper punch 2 is fixedly connected to the drill bit lock of the bench drill.

[0026] The worktable 1 is fixedly connected to the lower base of the bench drill, and the lower die 3 is fixedly installed on the top of the worktable 1.

[0027] The limiting component is used to sequentially arrange and limit multiple straight cylindrical silver-plated wires to the top of the lower die 3. During operation, to address the problems of low matching, poor consistency, and low production efficiency in the silver-plating wire forming process, this forming fixture, through the coordinated use of a bench drill, upper punch 2, lower die 3, and limiting component, achieves automation and batch processing of silver-plated wire forming. The bench drill is not shown in the diagram; the specific implementation is as follows: multiple cylindrical silver-plated wires are sequentially placed on the limiting component for limiting; the operating handle controls the drill bit lock of the control drill to press down, causing the upper punch 2 and lower die 3 to tightly fit and press the multiple cylindrical silver-plated wires, completing the silver plating of a specific shape. The process involves forming the silver-plated wire, then using a chip-retaining pliers to trim excess silver plating along both sides of the forming fixture. The drill handle is then released, the formed silver-plated wire is removed, and after inspection for aesthetics, it is used in production. This forming fixture, through the coordinated use of the drill, upper punch 2, lower die 3, and limiting components, achieves automated and batch forming of the silver-plated wire. The upper punch 2 is fixed to the drill bit lock of the drill, and the lower die 3 is fixed to the top of the worktable 1, ensuring stability and precision during the forming process. The limiting components are used to arrange multiple silver-plated wires sequentially onto the top of the lower die 3, ensuring accurate positioning and improving the consistency and matching of the forming process. This design solves the problems of low matching, poor consistency, and low production efficiency in manual silver-plated wire forming, improving both the quality of the finished product and production efficiency.

[0028] Through the above technical scheme, the forming tool shows remarkable advantages in practical application.
