To introduce a new kind of bodymaker punch planetary gear driving mechanism, this paper firstly summarized the cans forming and stretching movements; secondly, briefly analyzed the structures and working principles of the traditional bodymaker driving mechanism; thirdly, detailedly analyzed the structures and working principles of the new bodymaker punch planetary gear driving mechanism; finally, compared the traditional with the new driving mechanism bodymaker and obtained the excellent features of the new bodymaker driving mechanism. The traditional driving mechanism was essentially the slider-crank mechanism. The punch of the slider-crank mechanism was subject to a system of forces from horizontal and vertical direction, which badly affected the punch's performance. The new driving mechanism was essentially the planetary gear type linear motion mechanism. The punch would not change by vertical and horizontal direction component, without degrading performance of the punch. The features of the new bodymaker punch planetary gear driving mechanism are small vibration, good stability, and conformance with the design requirements.
