Description

Technical Field

[0001] The utility model belongs to the technical field of stamping equipment, in particular to a stamping device for producing cylindrical battery shells. Background Art

[0002] Cylindrical battery shell refers to the shell used to encapsulate cylindrical batteries, which is usually made of metal materials (such as steel) and has the function of protecting the internal structure and chemical substances of the battery from the influence of the external environment. When producing cylindrical battery shells, the metal sheet is processed by the die of the stamping equipment to finally obtain a cylindrical battery shell that meets the requirements. These equipments usually have the characteristics of high precision, high efficiency and high degree of automation, which can ensure that the produced battery shells have consistent quality and size.

[0003] At present, in the actual application of the existing cylindrical battery shell stamping equipment, it is found that due to the deformation of the steel plate, the product is tightly pressed against the inner wall of the lower mold and cannot be easily removed, which affects the subsequent processing efficiency and is not conducive to mass production operations. At the same time, some impurities will remain on the surface of the punch, affecting the use of the next stamping operation;

[0004] In order to solve the above problems, this application proposes a stamping device for producing cylindrical battery shells. Utility Model Content
