Description
Technical Field
[0001] This utility model relates to the field of charger terminal production technology, specifically a continuous stamping die and conductive sheet terminal. Background Technology
[0002] With the rapid development of electronic products, the demand for chargers, as essential accessories for various electronic devices, is increasing daily. Charger terminals, as one of the core components of a charger, directly affect the charger's performance and safety. Traditional charger terminal production methods often employ decentralized processing and manual assembly, resulting in low production efficiency and difficulty in guaranteeing product quality, failing to meet the demands of large-scale production.
[0003] To improve the production efficiency and product quality of charger terminals, the industry has begun exploring automated production using progressive stamping dies. Progressive stamping is a highly efficient and precise metal forming process that uses a series of ordered stamping actions to gradually process raw materials into finished products of the required shape and size. However, charger terminals have a complex structure, including multiple parts such as the main body, electrode parts, protrusions, protruding corner retaining parts, through holes, spherical surfaces, and rounded corners, and the dimensional and shape accuracy requirements between these parts are high. Therefore, we propose a die capable of continuously and precisely stamping out all parts of the charger terminal. Utility Model Content

Each stamping die includes an upper die base and a lower die base, and each stamping die has different forming components.
[0006] Furthermore, the forming components of the No. 1 stamping die include the No. 1 upper die core, the No. 1 lower die core, the No. 1 upper die head, and the No. 1 lower die head, with the ends of the No. 1 upper die head and the No. 1 lower die head both being configured as shrinkage sections.

They work together to form specific spherical and rounded corner shapes on the blank.
[0010] Furthermore, the forming components of the No. 5 stamping die include the No. 5 upper die core, the No. 5 lower die core, the No. 5 upper die head, the No. 5 lower die head, and the angled bending stamping rod. The angled bending stamping rod slides with the No. 5 upper die head and achieves angled bending on the inclined support platform of the No. 5 lower die head.

The right-angle bending stamping rod slides with the No. 6 upper die head and achieves right-angle bending on the right-angle bending reserved groove of the No. 6 lower die head.
[0012] In addition, the conductive sheet terminal can be obtained by the above-mentioned continuous stamping die, including a main body, an electrode part integrally connected to the end of the main body, the included angle between the main body and the electrode part is 90°, and a convex corner locking part is symmetrically provided at the bottom end of the electrode part. The upper and lower surfaces of the main body are connected to protruding posts, the ends of the protruding posts are provided with spherical surfaces, and a through hole is opened inside the main body. The upper and lower ports of the through hole are provided with rounded corners.
[0013] This invention provides a continuous stamping die and a conductive sheet terminal. Compared with the prior art, it has the following advantages:
[0014] This continuous stamping die and conductive terminal, through a series of precisely and ingeniously designed stamping die components, realizes a continuous, efficient, and automated production process for charger terminals, from initial cylindrical blanks to final precision finished products.

The No. 6 upper die core 71 carries the No. 6 upper die head 73 and the right-angle bending stamping rod 75 and moves down synchronously. The stamping force generated by the right-angle bending stamping rod 75 acts on the 45° electrode part of the No. 5 forming blank 67, so that the electrode part is pressed again. After being pressed, the electrode part is stamped to a 90° angle, and the final product 8 can be obtained.
[0043] Please see Figure 11 The cylindrical blank is placed in the forming groove of the first stamping die 2 and pressed to form a flat blank with a preliminary shape. The blank has a main body 81, an electrode 82, and a protruding post 86.
