Embodiment Construction

[0015] In order to have a clearer understanding of the technical characteristics, purpose and effect of the present invention, now in conjunction with the attached figure 1 And attached figure 2 The present invention is further described.

[0016] The present invention provides a cylindrical steel case lithium battery sealing combined upper die, its features The present invention provides a cylindrical steel case lithium battery sealing combined upper die, characterized in that: the upper die base 1 includes a fixed end and a hand-held convex The fixed end is a cylindrical structure. The upper mold is provided with a ring-shaped fixing groove. The handheld boss is also a cylindrical structure. The diameter of the handheld boss is larger than the diameter of the fixed end. There are 7 holes for bolts under the blind hole

[0017] There is a hard rubber pad 2 under the upper mold base 1, the outer diameter of the hard rubber pad 2 is the same as the hand-held boss of the uppe...

Abstract

The invention discloses a sealing combined upper die for a cylindrical steel shell lithium battery. The sealing combined upper die comprises an upper die base, wherein a hard rubber mat is arranged below the upper die base; a cover die base is arranged below the hard rubber mat; a cover die is fixed on the cover die base; and the hard rubber mat and the cover die base are arranged on an inner die in a sleeving manner, and the inner die is fixed on the upper die base through an inner hexagonal bolt. By adoption of the combined die disclosed by the invention, a sealing operation on the steel shell can be performed in one time, so that enlarging, opening crack or deformation of the steel shell can be prevented.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, and in particular relates to a combined upper mold for sealing a cylindrical steel case lithium battery. Background technique [0002] With the development of science and technology and the progress of the times, more and more electrical equipment appears in people's lives, and with the depletion of energy, the equipment originally driven by conventional energy is also moving closer to electric drive. It has gradually failed to meet people's needs. Therefore, the lithium-ion battery pack known for its high capacity, high rate, high cycle, and green energy has been widely developed and utilized. In the production process of lithium batteries, the battery case must be sealed to achieve the final shape of the battery, and the battery must be sealed with a corresponding sealing mold for sealing the lithium battery. Contents of the invention [0003] In order to solve the above technical...
