Abstract

The invention provides a stamping detection method for a new energy automobile battery pack upper cover. The stamping detection method comprises the following steps of S1, stretching and forming, specifically, stretching forming is conducted on a plate through a stretching die on a stretching station, in the stretching forming process, first edge pressing rib structures and second edge pressing rib structures which are not equal in height on the stretching die match and control the flowing direction of materials so as to ensure the forming quality. S2, trimming, specifically, the outer edge is punched and trimmed through a trimming die on a trimming station; S3, flanging and shaping, specifically, bending and flanging are carried out on the outer edge through a flanging and shaping die on a flanging and shaping station; s4, stamping, specifically, a stamping die on a stamping station is used for carrying out stamping treatment on a workpiece; and S5, air tightness detection, specifically, the air tightness detection is carried out on the finished product through an air tightness detection device on a detection station. According to the stamping detection method for the new energy automobile battery pack upper cover, the defects that an existing battery pack upper cover is poor in air tightness and low in machining efficiency are overcome.

Description

technical field [0001] The invention relates to the field of manufacturing the upper cover of an automobile battery pack, in particular to a stamping detection method for an upper cover of a new energy automobile battery pack. Background technique [0002] With the improvement of people's living standards, and the current trend of environmental protection, energy saving, and green ecological earth, new energy vehicles are developing more and more powerfully with the support of the state, and their applications are becoming more and more extensive. The battery pack module also develops rapidly accordingly. The battery pack cover is an important part of the battery pack module, which determines the service life and quality of the battery pack module. [0003] Such as figure 1 As shown, the existing battery pack upper cover has a raised portion on one side, a bent edge on the peripheral edge, and a plurality of through holes in the middle and the peripheral edge. Due to the ...
