Definitions

  • the invention relates to a powder press for the production of compacts of powdered molding material according to claim 1.
  • a press has at least one upper and lower punch, which interact with a die or a die bore in a die plate.
  • the punches are driven by a suitable power drive, for example a hydraulic cylinder. It is known to arrange the die plate firmly and to move upper and lower punches or alternatively to adjust only the upper punch and the die plate while the lower punch remains stationary.
  • the invention has for its object to provide a powder press, can be generated at the same time in a confined space with reduced wear with the several compacts.
  • the linear drives on electrically driven spindle drives, with which the linearly movable drive member is operatively connected to the power transmission bridge.
  • a spindle drive either the spindle nut or a worm wheel or the spindle rod is stationary. It depends on the structural conditions of the gear options, as the spindle drive is operatively connected to the press ram.
  • a piezosensor is arranged in the force path of the linear drive of the upper and / or lower punches. In this way, it is particularly well possible to precisely control each force path to avoid misalignment or bring different forces.
  • the die plate closer power transmission bridge has an opening through which the upper and / or lower punch the other power transmission bridge can pass. In this way it is possible to build the powder press very small.
  • the single figure shows very schematically drives for two punch of a powder press according to the invention and the regulation of the powder press for the upper punch.
  • a die plate 10 is shown with two die holes 12, 14.
  • a first punch 16 and a power transfer bridge 17, a second punch 18 is attached.
  • the upper punches 16, 18 cooperate with the die holes 12, 14 in a known manner.
  • a lower punch 22 is attached.
  • a further lower punch 24 is attached.
  • the lower punches 22, 24 cooperate with the die holes 12, 14 in a known manner.
  • the upper punch 18 extends through an opening 25 in the power transmission bridge 15 and the lower punch 24 extends through an opening 27 of the power transmission bridge 19th
  • bearings 50, 52 are arranged for spindle rods 54, 56 at opposite ends.
  • the spindle rods 54, 56 extend upwardly into a gear 58, 60, which is connected to an electric drive motor 62 and 64, respectively.
  • the rods 54, 56 move axially and thus actuate the power transmission bridge 15 and the upper punch 16.
  • an arrangement of two bearings 66, 68 provided for spindle rods 70, 72, the extending through gears 74, 76 which are connected to electric motors 78, 80.
  • the operation about the gear shown for the upper punch 18 corresponds to the upper punch 16th
  • the lower punches 22, 24 and the power transmission bridges 19, 23 are driven by analog spindle drives. They are omitted for ease of illustration.
  • a force sensor In each force path for each linear drive, a force sensor, not shown, is arranged, for example a piezoelectric sensor, in order to produce a regulation of the forces acting on the force transmission bridges 15, 17 forces either uniform or differentiated.
  • the regulation of the upper punch 16, 18 is indicated, namely by block 20 for the upper punch 18 and block 21 for the upper punch 16.
  • the gear 74 is assigned a position sensor 23 and the gear 76, a position sensor 25.
  • the upper punch 18 is a force sensor 27 and the upper punch 16 associated with a force sensor 29.
  • the transmission 58 is assigned a position sensor 31 and the transmission 60 is assigned a position sensor 33.
  • the regulations in the blocks 20 and 21 the adjustment of the power transmission bridges 15, 17 regulate. Either synchronously, so that a tilting of upper punches 16 and 18 is avoided or by deliberately different loading of the transmission bridges 15, 17 each As required. Because the drives, each of which has two power transmission bridge, are separately controlled, so that the various functions can be achieved.
  • the lines of action of the controls 20 and 21 to the drive motors 62, 64 and 87, 80 are not shown.
  • Analogous to the upper punches 16, 18 may be assigned to the lower punches 22, 24 position sensors, which are connected to a controller. Force sensors may also be associated with the linear drives for the power transmission bridges 19, 23, which are connected to the controllers. Thus, independent linear drive for the respective lower punch 22, 24 are provided.
  • the operation of the upper punch 16, 18 and lower punch 22, 24 is thus carried out via separate controller. It is therefore possible, in the arrangement shown, the force, which is exerted respectively by a linear drive or spindle drive on the power transmission bridge 15, 17 and 19, 23, set precisely. As a result, misalignments of the stamp 16, 18 can be avoided. In addition, it is possible to have different forces acting on a power transmission bridge, if desired.
