The invention relates to the technical field of tire forming, in particular to a mechanical drum sidewall turn-up driving device which comprises a cylinder and a turn-up assembly arranged on the periphery of the cylinder and used for turn-up of a sidewall. The first driving assembly is used for driving the turn-up assembly to move in the axial direction of the barrel body so as to enable the turn-up assembly to have a supporting position and a withdrawing position, and comprises an annular driving sleeve serving as the output end of the first driving assembly; the annular driving sleeve is arranged on the outer surface of the barrel in a sleeving mode and can move in the axial direction of the barrel, the annular driving sleeve has a certain axial length, and the length at least enables the lower surface of a connecting rod base in the turn-up assembly to be completely installed on the annular driving sleeve. The annular driving sleeve is arranged on the periphery of the cylinder body, so that the connecting
