Stamping mold for producing lithium battery cover

Abstract

The invention discloses a stamping mold for producing a lithium battery cover. The stamping mold comprises an upper mold plate, an upper mold frame is arranged at the bottom of the upper mold plate, and the upper mold plate and the upper mold frame are fixedly connected through a locking screw I; an upper mold core is embedded in the middle of the bottom of the upper mold frame, the upper mold core is fixedly connected with the upper mold frame through a plurality of locking screws II, the bottom end of the upper mold core penetrates through the upper mold frame and extends to the lower part of the upper mold frame, and round angles are formed in the edges of the bottom of the upper mold core; a plurality of cutters are arranged in the middle of the bottom of the upper mold core, a plurality of guide columns are arranged at the bottom of the upper mold frame, and the guide columns are located on the outer side of the upper mold core; and a lower mold core is arranged below the upper mold core, the lower mold core is embedded inside a lower mold frame, a mold cavity is formed in the top of the lower mold core, and the mold cavity is matched with the upper mold core. The stamping mold has the beneficial effects that the production efficiency and quality are improved, and great economic value is achieved.

Description

Technical field [0001] The invention relates to the technical field of lithium batteries, and in particular to a stamping die for producing lithium battery covers. Background technique [0002] Lithium battery covers are generally processed by stamping and forming lithium plates. In the traditional stamping and forming process, the bending radian and angle are calculated and simulated based on the rebound value and experience, and the rebound is suppressed through the process, which has achieved the purpose of compact forming, but the traditional mold compensation accuracy for the plate Confession and inaccurate positioning will make it difficult to form after pressing once and affect the appearance. At the same time, inaccurate positioning during placement will also lead to scrap and increase costs. [0003] For the problems in related technologies, no effective solutions have yet been proposed. Summary of the invention [0004] In view of the problems in the related technologies...

Problems solved by technology

In the traditional stamping forming process, the bending radian and angle are calculated and simulated based on the springback value and experience, and the springback is suppressed through the process, which has achieved the purpose of compact forming, but the compensation accuracy of the traditional mold for the plate Disclosure, inaccurate positioning, this will make it difficult to form after pressing once, affecting the appearance, and inaccurate positioning when placing, will also lead to the scrapping of the plate and increase the cost
