[0002] New energy vehicle batteries are new types of automotive batteries that use new energy technologies to reduce greenhouse gas emissions pollution. They can be divided into two categories, namely batteries and fuel cells. Batteries are suitable for pure new energy vehicles and can be classified as lead-acid batteries and nickel-based batteries. New energy vehicle battery packs are composed of multiple batteries stacked in series. A typical battery pack has about 96 batteries. For lithium-ion batteries charged to 4.2V, such a battery pack can generate a total voltage of more than 400V.

[0003] When processing the steel shell of new energy batteries, it is necessary to score the bottom of the steel shell in order to further improve the safety mechanism and explosion risk of the battery. Since the consistency of the score on the bottom of the steel shell ultimately determines the steel shell explosion value cpk, the optimization of the scoring process and mold is particularly important. The usual scoring mold adopts a split structure design. Although it is easy to replace, there is a gap in the split structure, which affects the residual thickness of the score and the final explosion value cpk.

Beneficial Effects

[0014] Compared with the prior art, the present invention provides an integrated engraving knife mold with improved burst value CPK, which has the following beneficial effects: The CPK integral engraving die for improving the burst value can drive the bidirectional lead screw to rotate by starting the set servo motor, so that the first movable block can be threadedly connected with the bidirectional lead screw. At this time, the first movable block can drive the limit assembly to move through the mounting block, so that the two limit assemblies can limit the battery steel shell that needs to be engraved. When the battery steel shell is engraved, the position of the battery steel shell can be guaranteed, which can effectively improve the processing accuracy.

[0015] The CPK integral engraving die for improving the bursting value can drive the upper die to be pressed down and the battery steel shell to move downward by starting the hydraulic lifting rod. When the battery steel shell moves downward, its outer wall will move at the roller, which will not affect the position of the battery steel shell and facilitate the engraving process. The engraving die is integrated with the lower die so that there will be no gap and the thickness of the marks on the battery steel shell after engraving and its final bursting value will not be affected. The yield and quality of the battery steel shell can be effectively guaranteed, and this structure can be adapted to the processing of battery steel shells of various sizes.

[0016] The CPK integrated engraving knife mold with improved burst value can drive the adapter block to move through the second movable block by pulling the provided handle, so that the adapter block can be separated from the outer wall of the clamping column and the inner cavity of the adapter groove, thereby separating the mounting base and the lower mold. When the engraving knife needs to be replaced, the lower mold can be directly replaced.

[0017] The CPK integral engraving die with increased burst value can, through the provided spring, bounce the adapter block outward through the second movable block in normal state, so that it can fit tightly in the inner cavity of the adapter groove and the outer wall of the clamping column. When the mounting base and the lower mold are installed, the tightness of their installation can be improved. The movable groove and the through groove are the same, and the movement of the mounting base and the lower mold will not be affected, thereby ensuring the limiting effect of the limiting assembly on the battery steel shell.
