Abstract
In a drive system of a forming press for driving the plunger with a crank mechanism controllable by a servomotor, the torques of the servomotors that are required to achieve a high pressure force for the plunger by means of intermediate gearing, preferably with a double gear transmission, to the cam or crank mechanism, wherein the symmetrically configured drive arms of multipoint presses for the right and the left pressure points of two-point presses or the pressure point groups of four-point presses are optionally mechanically synchronized with one another in such a way that each of the intermediate gears of the first or of one of the first gear transmissions is effectively connected to the others.
