摘要： Provided is a riveted battery cover which relates to the technical field of battery cover assembly. The riveted battery cover includes a terminal and includes a riveting block, an upper plastic insulator, a top cover, and a bottom insulator which are successively stacked. A first step hole and a second step hole are coaxially disposed in the riveting block. A stamped end of the terminal successively passes through the bottom insulator, the top cover, the upper plastic insulator, the first step hole, and the second step hole. A part of the stamped end of the terminal protruding from the first step hole is stamped to form a protrusion located in the second step hole.

摘要： A method for manufacturing an aluminum case of a battery includes: attaching an insulating layer to at least one surface of the plate body with an adhesive layer, wherein the adhesive layer is disposed between the insulating layer and the plate body; stamping, before the adhesive layer is cured, the plate body coated with the insulating layer to form the aluminum case in a predetermined shape, wherein during the stamping of the plate body, the insulating layer is movable relative to the plate body since the adhesive layer is not cured; and curing the adhesive layer after the stamping of the plate body is completed so that the insulating layer is fixed to the plate body, thereby avoiding detachment of the insulating layer and the plate body on the aluminum case.
