Shearing mold for battery case

Abstract

The invention discloses a shearing mold for a battery case. The shearing mold comprises an upper mold seat, a connecting plate, an upper base plate, an upper clamp plate, a puncher pin, a locating core, a concave mold plate, a guide rail assembly, an ejector rod, a lower mold cover plate, a lower base plate and a lower mold seat. The upper mold seat and the lower mold seat are in up-and-down correspondence. The connecting plate is mounted below the upper mold seat. The upper base plate is mounted below the connecting plate. The puncher pin is mounted below the upper base plate through the upper clamp plate. The locating core is mounted under the puncher pin. The guide rail assembly is mounted between the lower mold cover plate and the lower base plate. The concave mold plate is mounted above the guide rail assembly. The ejector rod is mounted below the guide rail assembly. The lower base plate is mounted on the lower mold seat. A first through hole used for locating the battery case isformed in the concave mold plate. The locating core is matched with the battery case. The shearing mold has the beneficial effects that one-time shearing forming is achieved, the shearing quality canmeet the use requirement, the time and manual cost are saved, and the yield is increased.

Description

technical field [0001] The invention relates to the related technical field of battery case manufacturing, in particular to a battery case shearing die. Background technique [0002] With the increasing attention to environmental pollution, new batteries have become an important part of the new energy field. New energy batteries have been widely used in the automotive and electronic fields. New energy batteries are an important part of new energy vehicles. It is also the core technology of new energy vehicles, and the quality of the battery determines the quality of the car. [0003] The structure of the new energy vehicle power battery mainly consists of a battery cover, a positive electrode, a diaphragm, a negative electrode, an organic electrolyte, and a battery case. Among them, the manufacture and research and development of battery shells are important engineering projects that our company is actively carrying out. From the perspective of different welding methods, b...

AI Technical Summary

Problems solved by technology

The existing shearing die cuts on one side, and the four sides of the shell mouth are not parallel. Poor welding between the battery shell and the cover plate will affect the quality of the battery; at the same time, it is time-consuming and labor-intensive, and the yield rate is also low.
