Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of battery production necking machines, and particularly relates to a turret-type fully automatic necking machine. Background Art
[0002] During the production process of batteries, there needs to be a certain gap when the wound core is inserted into the steel shell. Therefore, the steel shell used has a relatively large mouth diameter. After the insertion into the shell is completed, the necking machine reduces the mouth diameter of the steel shell.
[0003] In traditional cylindrical steel shell battery necking machines, the battery to be necked is placed directly below the necking die, and the necking die is driven by a lifting device to perform necking and shaping on the top of the shell from top to bottom.
[0004] In this kind of necking structure, since the working position of the necking die is fixed, when the battery is transported to the necking position, the battery needs to stop moving throughout the necking process to ensure that the necking and the battery do not get misaligned and to ensure the effect of battery necking and shaping.
[0005] However, this kind of necking structure has the following disadvantages: 1. To ensure that the necking and the battery do not get misaligned, the battery needs to stop moving throughout the necking process, making it difficult to ensure the continuity of each working position during the battery processing, and reducing the production efficiency of the battery. 2. During necking, since the battery opening faces upwards, when the die shapes the battery shell, the generated metal dust will directly fall into the interior of the battery shell, easily causing an internal short circuit phenomenon in the battery and affecting the safety of battery use.
