  • the upper and lower drive units furthermore each comprise an upper or lower spindle drive driven by the upper or lower drive motor with an upper or lower spindle and an upper or lower spindle nut.
  • the upper and lower spindle nuts are respectively connected to the upper and lower power transmission bridge, so that in a method of spindles in the spindle nuts, the upper and lower power transmission bridge is moved together with the respective spindle nuts in the axial direction.
  • the force exerted by the drive units force is transmitted via the respective power transmission bridge to the press unit. Due to the staggered attack of the drive units may occur in the course of the pressing process very high forces to a bending of the transmission bridges, which can lead to a bending moment on the spindle nuts and thus a deterioration of the function of the spindle drives in the prior art.
  • the invention provides that the upper and lower Spindle nuts or with the upper and lower spindle nuts respectively connected upper and lower fasteners are each connected by at least one upper or lower compensating element with the upper or lower power transmission bridge.

  • the compensation elements thus form a double joint.
  • the power transmission bridges in combination with at least two double joints reduce in comparison to the prior art, a transmission of bending moments occurring during operation on the spindle drives, in particular the spindle nuts, on. Any shortening of the power transmission bridge due to bending and thus a shortening of the distance between the bearing points of the compensating elements on the transmission bridges is compensated by rotating the compensating elements to the bearings. By bending the power transmission bridges resulting bending moments are therefore not on the spindle drives, in particular the spindle nuts transmitted.
  • the compensation elements according to the invention are in Essentially not flexible. Unlike in the prior art, no flexible elements are required, but the compensation of tilting moments via the tilting of the compensation elements made possible by the pivot bearing.
  • the spindle drives generate torques, in particular opposing torques, which can act on the power transmission bridge via the compensation elements. Such torques are generally undesirable. Therefore, a torque arm or rotation can be provided which prevents transmission of torque to the transmission bridges, but allows deflection of the transmission bridges.
  • stiffening plate As suitable in practice, for example, one each with the spindle nuts connected, for example, screwed, stiffening plate has proven, which may be arranged for example in a horizontal plane. The stiffening plate can be connected via one or more support elements to the power transmission bridge, for example, also be screwed.

  • the compensating elements can each be arranged on opposite sides of the power transmission bridge. By providing four compensation elements per power transmission bridge, the compensation effect is further optimized.
  • the bearings for the rotatable mounting of the compensation elements can be arranged one above the other in the resting state of the press, ie before a pressing operation, each in the vertical direction.
  • the rotatable mounting of the compensation elements thus takes place on vertically stacked sections of the respective power transmission bridges and the respective spindle nuts or fasteners. If there is a bending of the power transmission bridges in the course of pressing, the compensating elements tilt so that the bearing points are now arranged along a line running at an angle to the vertical. This results in a particularly uniform compensation effect.
  • any pivot bearing for the compensation elements are conceivable.
  • the rotatable mounting of the compensation elements can be done by rolling bearings or plain bearings.
  • the pivot bearings may each comprise bearing pins which are attached to the respective power transmission bridge and the respective spindle nut or the respective fastening element. At the compensation elements can then be provided to the bearing pin corresponding bearing.

These are particularly practical embodiments in order to safely avoid the aforementioned contacts during operation.
  • the gap or clearances can be chosen to be large enough, so that even in the course of compression maximum occurring bending of the power transmission bridge does not lead to an undesirable contact and thus a tilting moment on the spindle drives.
