Definitions

  • the invention relates to a toggle press with toggle lever pairs, which are preferably arranged symmetrically to each other.
  • Kniebelpressen originally developed for embossing coins and medals, were used in the subsequent period versatile in the forming technology but also as a jack or fruit presses.
  • a toggle fruit press is shown and described at http://de.wikipedia.org/wiki/Kniehebelpresse .
  • the two toggle lever pairs are connected by a spindle, the rotation of which changes the position of the toggle lever of the toggle lever pairs to each other.
  • the two toggle pairs are in turn suspended from a vertical spindle, which is supported in the bottom-side baling chamber and by turning the toggle lever with the Press punches without changing the position of the toggle to each other, let move in height.
  • the object of the invention is to change a toggle press so that the disadvantages, as described above in the fruit press, omitted and the benefits of toggle presses come into their own.
  • the first toggle press with a press frame having an upper platform and a press foot connected to the upper platform, wherein between the upper platform and the presser foot toggle pairs height adjustable using a mounted in the upper platform press frame spindle are arranged and the toggle pairs by means of a connecting toggle spindle for generating a pressing force to each other are adjustable in a spreading plane of the toggle pairs, wherein the pressing force on a Stempelfuß of the presser foot and thus on a workpiece holder of the presser foot is transferable, provides that the toggle pairs are connected on both sides and hinged to each of an upper and a lower connector platform, wherein the upper connector platform is coupled with the nozzle-like press frame spindle for height adjustment and the lower connector platform with the stamp foot and both connector platforms are arranged vertically adjustable in height on the press frame arranged guides.
  • the second toggle press with a press frame having an upper platform and a press foot connected to the upper platform, wherein between the upper platform and the presser foot toggle pairs height adjustable using a mounted in the upper platform press frame spindle are arranged and the toggle pairs by means of a connecting toggle spindle for generating a pressing force to each other in a spreading plane of the toggle pairs are adjustable, wherein the pressing force on a Stempelfuß of the presser foot and thus on a workpiece holder of the presser foot is transferable, provides that the toggle are pivotally connected to an upper connector platform and the Stempelfuß, wherein the upper connector platform coupled with the nozzle-like press frame spindle for height adjustment and the upper connector platform and the Stempelfuß are arranged vertically displaceable arranged on the press frame guides.
  • the two toggle presses thus differ in the design of the presser foot.
  • the guides connect the upper platform of the press frame to the upper platform of the press foot or workpiece holder.
  • two or four guides are arranged.
  • two guides these are preferably arranged on both sides of the toggle lever pairs with preferably the same distance from the spreading plane of the toggle lever.
  • the two guides, the one connector between the lower connector platform of the toggle lever and the stamp foot and the press frame spindle are arranged in one plane.
  • the upper platform of the press frame, the upper connector platform, the lower connector platform, if present, the upper platform of the press foot, if present, the workpiece receiver and the stamp foot have a rectangular and / or square base shape.
  • the connector and the nozzle-like press frame spindle can be arranged in a vertical axis through the intersection of the diagonals of the rectangular and / or square basic shapes.
  • the stamp foot is preferably guided on four supports, wherein the supports connect the workpiece holder and the upper platform of the presser foot with each other.
  • press frame spindle and / or the toggle spindle are driven by a motor, preferably by an electric motor.
  • the press frame spindle is connected only to the upper connector platform to the height adjustment and therefore may be formed like a nozzle. It ends at least in front of the toggle spindle, so that overlaps of the spindles are avoided.
  • the toggle spindle is only stressed during the generation of high pressing forces to train, so there is no risk of buckling.
  • the toggle spindle preferably works with a ball screw drive and the press frame spindle with a trapezoidal thread. The latter has the advantage that it has due to greater friction on a "self-locking".
  • the motor drive of the spindles takes place directly from the electric motors on or via a gear, e.g. a toothed belt.
  • the toggle presses can be used in one embodiment or as a combination of the two versions as modules in a press line.
  • a plurality of toggle presses of the same design or as a combination of the two embodiments are connected via a common punch foot and a common workpiece holder, wherein the spindle movements are synchronized.
  • the multiple toggle presses can act side by side and / or area distributed on the Stempelfuß configuration.
  • toggle presses have a press frame with an upper platform 1 and connected to the upper platform 1 presser foot 2. Between the upper platform 1 and the presser foot 2 toggle pairs 10, 11 are arranged.
  • the toggle pairs 10, 11 are height adjustable using a mounted in the upper platform 1 press frame spindle 8, which is designed like a clip and ends before the toggle lever 12.
  • Each toggle lever pair 10 and 11 consists of two levers which are pivotally connected to each other in the region of the bearing 13 of the toggle spindle 12, i. the toggle pairs 10, 11 are by means of connecting them toggle spindle 12 for generating a pressing force to each other in a spreading plane 16 of the toggle pairs 10, 11 adjustable, the pressing force on a Stempelfuß 5 of the presser foot 2 and thus on a workpiece holder 6 of the presser foot 2 is transferable.
  • the toggle pairs 10, 11 are each pivotally connected to the upper connector platform 14, wherein the upper connector platform 14 is coupled to the neck-shaped press frame spindle 8 for height adjustment.
  • the upper and lower connector platform 14, 15 can be stable in position in this embodiment by two guides 9 be held and moved. Both guides 9 are arranged on both sides of the toggle lever pairs 16 at the same distance to the spreading plane 16 of the toggle lever.
  • the guides 9 and the supports 7, which limit the pressing space are respectively arranged in the corner regions of the workpiece holder 6. As can be seen, both press spaces are identical despite different design of the "superstructure" and thus ideally suited for modular arrangements.
  • the upper platform 1 of the press frame, the upper connector platform 14, the lower connecting platform 15, depending on the version, the upper platform. 3 of the presser foot 2, if present, the workpiece holder 6 and the stamping foot 5 have a rectangular and / or square basic shape.
  • the connector 4 and the nozzle-like press frame spindle 8 are arranged in a vertical axis through the intersection of the diagonals of the rectangular and / or square basic shapes for symmetrical loading of the stamping foot 5.
  • four guides 9 are arranged symmetrically with respect to the vertical axis through the intersection of the diagonals in the corner regions.
  • these are arranged on both sides of the toggle lever pairs 16 at the same distance from the spreading plane 16 of the knee levers and the two guides 9, the one connector 4 between the lower connector platform 15 of the toggle lever and the die foot 5 and the press frame spindle 8 are preferably in one plane.
  • the press frame spindle 8 and the toggle spindle 12 are driven by the motors 17 and 18, respectively, preferably electrically.
