A curling spring pressing rod for cylindrical alkaline battery

Abstract

The invention discloses a hemming spring pressing rod of a cylindrical alkaline battery, belonging to the technical field of battery hemming devices, comprising a hemming frame, at least a pair of hemming wheels, and an upper pressing rod arranged in the hemming frame , the hemming wheels are symmetrically arranged on both sides of the upper pressing rod, and also include a bearing fixing sleeve arranged in the hemming frame, the lower end of the bearing fixing sleeve is fixedly connected with the upper pressing rod, and the The upper end of the bearing fixing sleeve is also provided with a spring. On the basis of the original crimping frame structure, the present invention designs the current collector and the upper pressure rod as a movable whole, and adopts a simple spring mechanism, so that the upper pressure rod receives the relative pressure and spring force of the current collector. Under the action of , it can move up and down flexibly, which not only reduces the requirements for the dimensional accuracy of the upper pressure rod, but also reduces the damage to the current collector by using the buffer force of the spring.

Description

technical field [0001] The invention belongs to the technical field of battery hemming devices, in particular to a hemming spring pressing rod of a cylindrical alkaline battery. Background technique [0002] As the main energy source of national life, alkaline zinc-manganese dry battery is one of the most important batteries in the current battery market. The same type of alkaline battery has 3-7 times the capacity and discharge time of ordinary batteries, and there is a gap between the two in low temperature performance. bigger. As an environmentally friendly primary battery, with the advent of the era of digital electrical appliances, the improvement of people's living standards and the enhancement of environmental protection awareness, alkaline zinc-manganese dry batteries have occupied the mainstream market of battery consumption. [0003] The manufacturing process of the alkaline battery is that after the positive and negative electrode materials are filled inside the ...

Problems solved by technology

So far, the steel casing of cylindrical alkaline batteries mostly uses pressure rods to withstand the current collector, and uses the high-speed rotation of the curling wheel to make the opening of the steel casing inward. Due to the different properties of different steel casings, the battery The difference in the depth of the engraved line makes the height of the current collector different after insertion. Such a structure has high requirements for the length of the pressure rod, and the pressure of the pressure rod on the current collector is difficult to control, which is easy to cause damage to the current collector. A new process must be adopted
