Similarly, the drive system 1 can also adopt components such as motors used in multi-station presses in the prior art. Components (its specific structure can be designed according to needs, no specific restrictions are made here), since the drive system 1 and transmission system 2 need to use lubricating oil, so some of the structures (such as gears, bearings and other components) need to be arranged on the beam 33, in order to facilitate the collection and circulation of lubricating oil.
