Definitions

  • the invention relates to a Doppelbäumschere, with a stationary lower blade and a raised by eccentric shafts over connecting rods and lowerable driven upper blade, each connecting rod is arranged on a separate eccentric shaft and the upper blade due to different crank radii whose offset and different connecting rod lengths executes a rolling cut movement by a sliding block is led.
  • Sheet metal or Beklamscheren this type are known for example from DE 23 29 096 A1 or DE 25 10 881 A1.
  • the currently used double trimming shears which are driven by crankshafts, are not variable with respect to the cutting movement.
  • the upper knife carriage which is coupled by means of rigid connecting rod with the eccentric shafts, allows no change in the articulation points.
  • the bow knife performs a rolling cut movement, which is composed of the different crank radii, their offset and the different conrod lengths.
  • the knife is guided in the cutting direction by means of rotatably mounted sliding block.
  • the section thickness can not be increased arbitrarily.
  • the material feed is determined by the largest sheet thickness, so that with thin sheets only a lower throughput is possible.
  • the invention is therefore an object of the invention to provide a Doppelbäumschere whose cutting movement is variable, so that an adaptation to different cutting thicknesses, larger sheet thicknesses and a variable material throughput are possible.
  • each connecting rod is arranged on a separate eccentric shaft and the upper blade performs due to different crank radii whose offset and different connecting rod lengths a rolling cut movement , which is guided by a sliding block in that the length of the connecting rods is changeable.
  • each connecting rod is divided by a nut / spindle connection and the change in the length of the connecting rod by relative rotation of the nut relative to the spindle.
  • each connecting rod is divided by a piston / cylinder connection and the change in the length of the connecting rod is effected by relative displacement of the piston to the cylinder.
  • each connecting rod can be subdivided by an eccentric connection and the change in the length of the connecting rod is effected by relative rotation of the eccentric connection.
  • the core idea of the invention thus consists in that the connecting rod lengths can be changed by incorporating actuators in their effective length.
  • the height of the upper blade and thus the immersion depth can be changed.
  • the solution according to the invention thus enables cutting over a greater thickness range.
  • an adaptation of the material feed is possible, namely thickness-dependent, so that in turn higher throughputs can be achieved with thinner sheets.
  • Fig. 2 shows a corresponding embodiment with a piston / cylinder actuator
  • Fig. 3 shows the variability by means of a Exzenteranordung as an actuator.
  • each of the crank mechanism is designated by 1 and the upper blade by 2.
  • the connecting rods are provided with the reference numeral 3.
  • FIG. 2 The representation in FIG. 2 is accordingly the same, with a piston / cylinder actuator acting as the actuator. Arrangement 6 is provided.

Abstract

L'invention concerne une cisaille double à rogner, avec une lame inférieure fixe et avec une lame supérieure entraînée en un mouvement ascendant et descendant par des arbres excentriques par l'intermédiaire de bielles. Chaque bielle est disposée sur un propre arbre excentrique. Grâce à différents rayons de manivelle, à leur décalage et à différentes longueurs de bielle, la lame supérieure accomplit un mouvement de coupe roulant qui est guidé par un coulisseau, sachant que la longueur des bielles est variable.
