This invention discloses a sodium-ion battery rolling device, including a rolling assembly comprising a pressure roller and a side frame. The rolling assembly further includes a driven roller and a steel strip. The steel strip is sleeved on the outside of the pressure roller and the driven roller. The contact portion between the steel strip and the slurry coating forms a compression section. The contact surface between the compression section and the slurry coating is sloped, with the slope facing the pressure roller. The driven roller has reciprocating components on both end faces that drive the compression section to reciprocate along the contact surface with the slurry coating, with the reciprocating movement direction perpendicular to the slurry coating transport direction. This invention increases the compression path of the slurry coating and reduces the compression amount by using the compression section, ensuring the internal material uniformity of the slurry coating after rolling. Furthermore, the reciprocating compression section can smooth out minor protrusions on the surface of the slurry coating, ensuring the final uniformity of the slurry coating thickness and effectively guaranteeing the final product quality.

This utility model relates to a tooling for shaping the groove of a battery steel shell, comprising: an upper mold fixed to the movable end of a stamping equipment; and a lower mold consisting of two semi-circular mold bodies that are fitted together, each semi-circular mold body having a stepped shaping part at its center, the stepped shaping part including a continuously connected upper flat section and a lower arc-shaped section; the lower mold is fixed to the fixed end of the stamping equipment and is fitted outside the groove position of the steel shell. The stepped shaping parts of the two semi-circular mold bodies fit together to form a mold cavity, through which the groove of the steel shell is formed into a composite structure of an upper flat groove and a lower arc-shaped groove. This utility model, through the design of the stepped shaping part of the lower mold, enables the groove of the steel shell to form a composite structure of an upper flat groove and a lower arc-shaped groove. This structure achieves surface contact with the cap during sealing, significantly increasing the support area, effectively dispersing the sealing pressure, effectively reducing leakage at the sealing ring, and ensuring reliable sealing.
