Edge rolling device of battery shell and battery shell

Abstract

The utility model relates to the field of batteries, in particular to an edge rolling device of a battery shell and the battery shell. The battery shell solves the problems that the edges of the existing battery shell are mostly single sealed edges, so that the edges may fall off in the future use process, the shell is exposed due to the separation of the edges, and the shell is damaged. The device comprises a workbench; the device comprises a workbench, and further comprises four sets of edge rolling hydraulic cylinders, four sets of edge rolling rollers, eight sets of edge folding assemblies, eight sets of edge covering assemblies, two sets of linear motors and a bottom punching assembly, sliding rod sets are arranged on the four edges of the workbench, sliding shaft sets are slidably connected to the outer surfaces of the sliding rod sets, and two sets of edge rolling blocks are fixed to the output ends of the two sets of edge rolling hydraulic cylinders through extension frames correspondingly; the device is formed through one-time edge covering, the attaching degree of the covered edge and the battery shell is guaranteed, meanwhile, construction steps are reduced, the covered edge connecting position of the battery shell is wrapped in a double-layer mode, the sealing performance of the covered edge of the battery shell can be guaranteed, the covered edge of the device is integrally formed, and the attaching degree of the covered edge is guaranteed.
