A method for the control of a ram movement and ram forces of multi-point servo hybrid presses, where the positions, speeds and forces to drive the ram can be controlled independently of each other by the servo motor, which is assigned to each pressure point or each group of pressure points, for the main drive for the ram movement in the main function and the hydraulic pressure cushions, which are separately assigned to each pressure point of the ram, in an auxiliary function, to influence process-induced position and force settings of the ram in a combinatory interaction to achieve an active control of draw depth and tilt.

Method and device for closed-loop control of ram movement and ram forces in multi-point servo hybrid presses

The invention relates to a press drive by means of direct drive modules, wherein a space-saving construction with low height for the press can be achieved.

Drive system for a forming press

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.
