A forming device for a lithium-ion power battery cover plate and a processing method thereof

Abstract

The invention relates to a forming device for a lithium ion power battery cover plate and a machining method of the forming device. The forming device comprises a forming frame, an executing mechanismis arranged in the middle of the upper end of the forming frame, locking mechanisms are symmetrically arranged at the left end and the right end of the forming frame, the upper ends of the locking mechanisms abut against the locking blocks, the locking blocks are arranged on locking air cylinders correspondingly, and the locking air cylinders are fixed on the forming frame. The forming device andthe machining method can solve the following problems, existing in forming machining process of an existing lithium ion battery cover plate, that a, existing hole opening operation of the battery cover plate cannot accurately control the strength of cutting machining, and damage and deformation of a base material can be easily caused during operation, so that the base material needs to be subjected to secondary machining and repairing; and b, a special clamp is adopted to fix the base material in a traditional forming drilling operation, the operation is complex, base material taking and placing is troublesome, the consumed time is long, the base material is not fixed through simple placement, potential safety hazards exist, and the stability of the machining operation is poor.

Description

technical field [0001] The invention relates to the technical field of electric power cross arms, in particular to a forming device for a cover plate of a lithium-ion power battery and a processing method thereof. Background technique [0002] Lithium-ion batteries have high energy density and high average output voltage. Excellent cycle performance, fast charging and discharging, high charging efficiency, and high output power. long lasting. The packaging of lithium-ion batteries is very important to the service life of lithium-ion batteries, especially the processing and production of the cover of lithium-ion batteries is very important for the connection between the battery and the accessories during use, and the cover of lithium-ion batteries It is necessary to open a round hole in the middle, and the cutting effect of the round hole on the lithium battery cover directly affects the service life of the lithium ion battery. [0003] However, the following problems exis...

Problems solved by technology

[0003] However, the following problems exist in the forming process of the existing lithium-ion battery cover plate, a. The existing battery cover plate cannot accurately control the cutting strength during the drilling operation, and the base material is easily damaged and deformed during the operation. It is necessary to carry out secondary processing and repair on the base material. In the traditional forming and drilling operation, special fixtures are used to fix the base material. And the stability of the processing operation is poor

[0004] Regarding some problems in the processing of battery cover plates, related industries have made research and proposed specific technical solutions, such as the Chinese utility model patent No. 2018212614385, a battery cover automatic feeding and cutting device, which can Quickly cut and process a batch of battery covers. However, the problems mentioned above about the processing and molding of lithium-ion battery covers have not been involved.
