Definitions

  • the invention relates to a device for actuating a tappet in a lifting or Clamping device, in particular for folding sheet metal in automobile construction, where a drivable plunger with a folded bed lying in a base frame is guided and presses the sheets to be folded against fixed folding tools.
  • WO-A-97/49128 a press device is described, the Press ram is supported on a wedge surface, which is used to actuate the ram can be adjusted by an electric motor on a sliding surface.
  • the object of the invention is to hydraulic or pneumatic systems Abandon generation and transmission of the necessary power.
  • the wedges having the wedge surface on the base frame be led.
  • the wedges are preferably substantially orthogonal to the working direction of the Ram adjustable.
  • the wedges Threaded nut for an electric motor driven therein Screw drive arranged.
  • the spindle rotates, the wedges are adjusted and so that the ram is raised or lowered.
  • the threaded nuts preferably have a ball screw.
  • the spindle of the screw drive can be coupled with an electric motor be connected.
  • the electric motor is preferably an intermediate converter the electric motor and the clutch can advantageously be a gear be switched.
  • the spindle can be in an axial spherical roller bearing be led.
  • the device which is preferably referred to as an electromechanical lifting unit, can are used in the areas of clamping technology, folding and Flanging technology and also in special areas of conveyor technology.
  • a vertically up and down plunger 1 is shown, the on the top side a folding bed, not shown, for the body panels to be folded can carry. Above the folding bed are not shown fixed folding tools.
  • the plunger 1 is guided in a base frame 3. Below the plunger 1 there are horizontally adjustable wedges 17, 18 which are on on the base frame 3 arranged slide plates 6 are guided. On the pestle 1 facing oblique wedge surfaces 7, the plunger 1 is supported.
  • a left lower wedge 17 and a right lower wedge 18 are opposite inclined wedge surfaces 7 with the help of a common screw drive 20 Threaded nuts 21, 22 with left and right hand threads in opposite Movable directions.
  • the screw drive 20 is of a common Electric motor 16 driven via the clutch 14 and has the end Bearings 23 and 24.
