Original Abstract Submitted
A necking-flanging roller and a necking-flanging mechanism are disclosed. The necking-flanging roller is used to form the necking portion and the flanging portion on the housing, including a roller body; and a limiting portion, arranged along the axial direction of the roller body and oppositely to the roller body, wherein a gap is formed between the roller body and the limiting portion, and the gap is provided for the free end of the flanging portion to insert therein and restricts the free end from bending and deforming. The technical solution provided in the present disclosure can improve the quality of the battery.
