Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die for preventing deformation of battery connector pieces. Background Technology

[0002] A battery connector is a metal piece used to connect batteries. It is usually made of stamped metal and belongs to the category of electronic hardware materials. The battery connector plays a vital role in the battery system. It not only connects the positive and negative terminals of the battery to ensure the flow of current, but also fixes and protects the battery. The battery connector needs to be stamped and formed using stamping dies during the manufacturing process.

[0003] For example, announcement number CN210450604U (titled "A Battery Connector Stamping Die") includes a fixed die assembly and a movable die assembly arranged from top to bottom. The fixed die assembly includes a lower die base, with a lower template fixed above the lower die base. The movable die assembly includes an upper die base, an upper clamping plate, and a stripper plate arranged from top to bottom. The upper die base and the upper clamping plate are stacked together. Several guide posts passing through the upper clamping plate and the stripper plate are provided on the upper die base. Each guide post has a limiting protrusion below the stripper plate to restrict its downward movement. An elastic element is also fitted between the guide post and the upper clamping plate. The movable die assembly cooperates with the fixed die assembly to complete the stamping of the battery connector material, ensuring... To ensure rapid prototyping of battery connector strips, the lower die base of the fixed die assembly is equipped with a lower die plate for punching, while the upper die base of the movable die assembly has an upper clamping plate below it. The stripper plate below the upper clamping plate can slide along the guide post. When punching the battery connector strip material, the entire movable die assembly moves toward the fixed die assembly. During the downward movement of the movable die assembly, the stripper plate at the bottom of the movable die assembly first touches the lower die plate of the fixed die assembly. The stripper plate can press down on the battery connector strip material strip inside the lower die plate, improving the stability of the battery connector strip material strip during punching. When the upper die base continues to move downward, it can press down the stripper plate to punch the battery connector strip material strip. The punched battery connector strip material strip can then be formed.

[0004] The aforementioned stamping die improves the stability of the battery connector during the stamping process through the setting of the pressing mechanism. However, the material removal after stamping is inconvenient, which leads to the problem of deformation of the battery connector due to improper material removal operation. To address this, we provide a battery connector anti-deformation stamping die. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1-5 An embodiment of this utility model is provided: a battery connector anti-deformation stamping mold, including a mold base plate 1 and a mold top plate 3. A base seat 6 and a top pressure seat 7 are integrally formed on the inner walls of the mold base plate 1 and the mold top plate 3, respectively.
