Shaping device for electrode lug of side negative plate

Abstract

The invention discloses a shaping device for an electrode lug of a side negative plate. The shaping device comprises a bottom plate. The bottom plate is provided with a plurality of locating columns. The locating columns are provided with guide rods and a shaping die plate capable of moving vertically along the guide rods. A panel is fixed to the tops of the guide rods. A starting mechanism capable of enabling the shaping die plate to be pressed is arranged below the panel. The portions, between the shaping die plate and the locating columns, of the guide rods are sleeved with return springs. The shaping die plate is provided with a plurality of rectangular shaping holes. The inner walls of the shaping holes are inclined towards the centers of the shaping holes from bottom to top. Rolling mechanisms acting on the inner side of the electrode lug through pressing wheels are arranged in the shaping holes. According to the shaping device for the electrode lug of the side negative plate, the shaping strength and angle on shaping of the electrode lug of the side negative plate are uniform, and the potential quality hazard of the short circuit due to the fact that the electrode lug is made manually can be effectively avoided.

Description

technical field [0001] The invention relates to the field of storage battery manufacturing, in particular to a device for shaping tabs of side and negative plates. [0002] Background technique [0003] At present, machine casting and welding are used in the production process of batteries to replace the original manual casting and welding. However, in the production process, due to the differences in the assembly pressure of the single-cell clusters, the inner diameter of the single-cell cast-welding fixture is deformed due to long-term use, which cannot meet the requirements of the process. Welding, chip off) hidden dangers. In order to effectively improve the welding quality of the side and negative plates, the assembly staff lightly pinches the side and negative plates of each cluster inward at a certain angle when the clusters are put into the slot. When it is heavy, it is easy to produce short-circuit phenomena such as loose living material in the lower frame of the...

In order to effectively improve the welding quality of the side and negative plates, the assembly staff lightly pinches the side and negative plates of each cluster inward at a certain angle when the clusters are put into the slot. When it is heavy, it is easy to produce short-circuit phenomena such as loose living material in the lower frame of the tab and penetration of the partition, which seriously affects the quality of the product.
