  • Patent number: 10870251
    Abstract: 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.
    Type: Grant
    Filed: April 6, 2017
    Date of Patent: December 22, 2020

  • Patent number: 8549940
    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.

  • Publication number: 20090260460
    Abstract: A drive system of a forming press for driving the plunger with a crank mechanism controllable by a servomotor is refined in such a way that on the one hand a high pressure force is achievable with the available torques of servomotors and that on the other hand the technical complexity of the drive is reduced during the design of the drive with multiple mechanically synchronized pressure points and also with pressure points that can each be controlled independently of one another.
