Description

Battery cell pole column riveting tool

Technical Field

The utility model belongs to the technical field of batteries, and particularly relates to a riveting tool for a battery core pole.

Background

The principle of the riveting tool for the traditional battery cell product is that a riveting nail is fixed, and after the cylinder generates thrust, a pressing block is driven to press the pole, so that the pole and the riveting nail are riveted. However, the thrust of the cylinder cannot be changed to a fixed value. The polar post and the riveting nail are easy to be in a non-expected riveting state or are in over-riveting state, and the riveting pressure cannot be controlled in the riveting process. If the post and the rivet are not in the expected riveting state after riveting, the sealing ring may not reach the expected compression deformation, so that the post is not completely sealed, a liquid leakage phenomenon can occur in the subsequent liquid injection process, and the cell product is scrapped; if the post and the rivet are riveted after riveting, the sealing ring is excessively deformed and compressed, and is likely to be broken, and even other components such as the plastic support are greatly deformed, and the leakage phenomenon of the post in the liquid injection process is also caused.
