Ear bender

Abstract

The invention discloses an ear bender which comprises a compacting device and a movable knife block, wherein the movable knife block and one end of the compacting device form a scissor fork mechanism, a pole piece is fixed through the compacting device, and the pole ear of the pole piece is bent through the engagement of the scissor fork mechanism; the invention has simple and compact structure, is convenient to operate, can replace original manual ear bending, reduce the labor intensity of operating personnel, simultaneously realize the ear bending of two pole pieces, and improve the ear bending efficiency; and the bending angles of all the pole ears are unified through the control for the engagement degree of the movable knife block and the compacting device, thereby the situation of irregular ear bending sizes of the pole ears is avoided, and the quality of storage battery products is improved.

Description

technical field [0001] The invention relates to the technical field of storage battery manufacturing, in particular to a curved earpiece used for processing battery pole pieces and lugs. Background technique [0002] At present, there are tabs on the pole pieces of lead-acid batteries. After the pole pieces are manufactured, there is a bending process. The purpose is to bend the tabs at a certain angle to meet the process requirements. However, most of the existing pole pieces are lead castings. , a storage battery is composed of multiple pole groups, and each pole group is arranged by multiple pole pieces. If manual bending is used, the efficiency is low and the labor intensity is high, and the size of the bending ears of the poles is uneven, which affects Battery quality. The State Intellectual Property Office of China disclosed an automatic bending machine for battery tabs on 2008-01-02, which can realize automatic bending of tabs, but its structure is relatively complic...

[0002] At present, there are tabs on the pole pieces of lead-acid batteries. After the pole pieces are manufactured, there is a bending process. The purpose is to bend the tabs at a certain angle to meet the process requirements. However, most of the existing pole pieces are lead castings. , a storage battery is composed of multiple pole groups, and each pole group is arranged by multiple pole pieces. If manual bending is used, the efficiency is low and the labor intensity is high, and the size of the bending ears of the poles is uneven, which affects battery quality

The State Intellectual Property Office of China disclosed an automatic bending machine for battery tabs on 2008-01-02, which can realize automatic bending of tabs, but its structure is relatively complicated, and the industry urgently needs a simple structure and easy operation. ear bending device to replace artificial ear bending
