It should be noted that, in practical applications, those skilled in the art may set the limiting member 32 to be welded with the shaping punch 31, or may set the limiting member 32 to be connected with the shaping punch 31 through a fastener, or may set the limiting member 32 to be integrally formed with the shaping punch 31, etc., and such adjustments and changes on the specific connection manner of the limiting member 32 and the shaping punch 31 do not deviate from the principle and scope of the present utility model, and are included in the protection scope of the present utility model.

Preferably, the stop member 32 is integrally formed with the shaping punch 31.

By such arrangement, on the one hand, the loosening between the shaping punch 31 and the stopper member 32 due to the loose connection between the shaping punch 31 and the stopper member 32 can be prevented; on the other hand, it is possible to prevent the shell opening from being scratched by the presence of a weld between the shaping punch 31 and the stopper member 32, thereby avoiding affecting the shaping effect.

It should be noted that, although the present utility model is described by taking a cylindrical battery as an example for the shaping device, this is not limitative, but, for example, the square casing of the square battery may be shaped, and accordingly, the section of the inner wall of the shaping ring 20 may be set to be square corresponding to the square casing, or the casing 1 of the battery may be shaped in any other possible shape, etc., and the adjustment and modification of the shaping object do not deviate from the principle and scope of the present utility model, and are included in the protection scope of the present utility model.

It is of course preferable to set the cross section of the inner wall of the shaping ring 20 to be circular in order to shape the case 1 of the cylindrical battery.

Thus far, the technical solution of the present utility model has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present utility model is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present utility model, and such modifications and substitutions will fall within the scope of the present utility model.
