Abstract

The invention provides a stamping system for the upper cover of a battery pack of a new energy vehicle, which includes a stretching station, a trimming station, a flanging shaping station and a punching station arranged in sequence, and the four stations are respectively arranged correspondingly There are stretching dies, trimming dies, flanging shaping dies and punching dies; during production, stretch forming, outer edge punching and trimming, outer edge bending and flanging, and punching are performed on the sheet to be processed in sequence; The outer ring of the die of the drawing die is provided with a first bead structure of unequal height, the outer ring of the punch of the drawing die is provided with a second bead structure, and the first bead structure is the same as the first bead structure The above-mentioned second bead structure cooperates to control the material flow direction to prevent cracking and wrinkling; a stamping system for the upper cover of a new energy vehicle battery pack provided by the present invention adopts four stations and corresponding four molds, which can The product is stamped and formed at one time, and its airtightness is good, which can meet the airtightness requirements of the product.

Description

technical field [0001] The invention relates to the field of stamping and forming, in particular to a stamping system for the upper cover of a battery pack of a new energy vehicle. 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 large volume of the upper cover of the battery...
