Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a continuous stamping die for a battery cap. Background Art

[0002] Battery cap refers to a protective cover used to cover or seal the top of the battery. The battery cap can provide additional physical protection to prevent damage to the components, electrolyte or battery fibers inside the battery. The battery cap can seal the top of the battery to prevent dust, moisture or other external substances from entering the battery, thereby reducing the risk of contamination or damage to the battery. The battery cap usually contains connection points for fixing the positive and negative poles of the battery to ensure that the battery is stably connected during use. Battery cap stamping refers to the process of producing battery caps using stamping technology. In the battery manufacturing industry, battery caps are usually processed by metal stamping.

[0003] In the battery cap stamping production process, most of the metal coils are stamped by unfolding them. However, after stamping, the remaining metal coils need to be wound up by a winder, which increases the cost of use.

[0004] In view of this, we propose a continuous stamping die for a battery cap. Utility Model Content
