Abstract

The invention relates to the technical field of battery production equipment and discloses a necking device. The necking device comprises a material holding assembly, a guiding assembly and a neckingpart and a limiting part. The material holding assembly is used for mounting a battery shell. The limiting part is arranged in the necking part, and the necking part and the limiting part are arrangedopposite to the material holding assembly. The guiding assembly is connected to the necking part and the limiting part for guiding the necking part and the limiting part to move toward the material holding assembly, so that the end part, close to the material holding assembly, of the limiting part can stretch into the battery shell mounted on the material holding assembly and the necking part necks a shell aperture of the battery shell. In this way, the necking quality of the shell aperture of the batter shell can be improved.

Description

technical field [0001] The invention relates to the technical field of battery production equipment, in particular to a necking device. Background technique [0002] In the production process of cylindrical batteries, it is necessary to shrink the opening of the steel shell of the cylindrical battery, that is, to reduce the diameter of the opening of the steel shell of the battery, so as to avoid the internal structure of the steel shell of the battery, such as the battery core, etc. from falling out of the shell. . However, the traditional necking device only directly pushes the battery steel case to shrink the battery steel case through the necking piece set outside the mouth of the battery steel case, resulting in pinch marks or wrinkles easily appearing at the mouth of the battery steel case Neck quality is lower. Contents of the invention [0003] In view of this, the technical problem mainly solved by the present invention is to provide a necking device, which can ...
