The invention relates to the technical field of batteries, and discloses a cover plate assembling and forming process and a cover plate. The pole comprises a bottom plate, a body part and an annular vertical wall, the body part is arranged on the upper surface of the bottom plate, and the annular vertical wall is annularly arranged on the outer edge of the upper surface of the body part. According to the cover plate assembling and forming process, the annular vertical wall is arranged on the body part of the pole, when the cover plate is assembled and formed, the pole penetrates through the mounting holes in the lower insulating part and the cover plate body, then the upper insulating part sleeves the body part from top to bottom, and then the annular vertical wall is stamped so that the annular vertical wall can be bent downwards and attached to the upper surface of the upper insulating part; and the pole is fixed on the cover plate body. According to the cover plate assembling and forming process, the pre-r
