Embodiment Construction

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0037] In view of the difficulty in forming stamping parts on the battery case of a certain car model in the prior art, refer to Figure 2-11 , the embodiment of the present invention provides a new type of stamping parts forming process on the battery case, including the following steps:

[0038] S1: Blanking, confirm the stamping direction and the size of the four pieces of stamping parts after mold clamping, and outline the outer edge shapes of the four pieces on the surrounding edges of the material one by one, and perform the blanking operation , to obtain four single-piece molded parts to be stamped;

[0039] S2: The first flanging forming, placing the material to be stamped on the first die 1, and limiting the circumferential direction of the material t...

Abstract

The invention relates to the technical field of the stamping process, and discloses a forming process for a stamping part on a battery shell. The stamping process integrating four pieces is adopted and includes the process flow of blanking, the first time of edge turning forming, trimming, the second time of edge turning forming, punching and splitting. The stable positioning of the stamping part in the stamping direction is achieved. Material parts uniformly bear force in the stamping process. The smooth forming of the stamping part is achieved. The stamping quality of the stamping part is improved. Compared with the prior art where four single pieces are independently stamped, use of dies is saved, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of stamping technology, in particular to a forming process of stamping parts on a battery case. Background technique [0002] The structure of the stamping parts on the battery case of a certain model is as follows figure 1 As shown, the stamped part consists of four single pieces, which are formed by stamping with a steel plate die. In the prior art, the stamping and forming of the steel plate mold generally adopts a single-piece forming or left and right pieces of the molding process structure, and the four single-pieces in the stamping part are respectively punched by blanking-up flanging-bottom flanging-punching stamping process. However, due to structural limitations, it is difficult to position in the stamping direction during the forming process, and it is difficult to position and form well during the up and down flanging process, and it is difficult to meet the stamping quality requirements.
