Definitions

  • the present invention relates to a pressing device according to the subject matter of claim 1.
  • Pressing devices are known from the prior art.
  • the EP 2 340 899 such a pressing device.
  • Two levers act on press jaws.
  • the levers are articulated to a pressing jaw carrier and communicate with it via a bolt in each case.
  • the pressing jaw is designed to be pivotable about the bolt relative to the pressing jaw carrier.
  • the bolt after the EP 2 340 899 is held by a screw and two lids in the press jaw carrier.
  • press devices have become known in which the bolt is held by releasable retaining rings in the die backing.
  • a press device has become known, wherein a predetermined breaking point is present, which breaks at the occurrence of excessive force at a defined location. Per bolt opening a predetermined breaking point is arranged, which leads to the problem that break one or both of the predetermined breaking points in case of failure, the pressing lever together with the bearing pin of the pressing device can solve with great energy from the pressing device.
  • the invention has for its object, a Specify pressing device, which overcomes the disadvantages of the prior art.
  • the pressing device should be safer to use.
  • a pressing device comprises at least one carrier element with at least two carrier tabs, in which at least one carrier opening is arranged, and at least one pressing element with at least one bearing opening for applying a pressing force to a compact, wherein the at least one Pressing element is mounted pivotably about at least one pivot axis on the support element.
  • the bearing and the pivot axisbidstellender bolt extends through the at least one support opening and the bearing opening therethrough.
  • At least one of the carrier straps is formed with a larger proportion of material than the other of the carrier straps.
  • the proportion of material of the carrier element in the region of one carrier lug is greater than the material content of the carrier element region of the other carrier lug.
  • the material shares between the carrier tabs are so different.
  • the carrier straps are asymmetrical with respect to the material portion.
  • proportion of material is understood to mean a greater weight and volume training.
  • the greater proportion of material forms an integral part of the carrier lug. This means that the carrier flap with the larger material content is formed differently with respect to its outer shape than the carrier flap without the larger material content.
  • the larger proportion of material preferably has the same material properties as the rest the carrier tab on.
  • two spaced carrier elements are arranged with the said larger material proportions.
  • the two carrier elements are arranged relative to one another in such a way that the carrier lug with the larger material portion of the first carrier element lies above the carrier lug without the larger material portion of the second carrier element, and that the carrier lug without the larger material portion of the first carrier element over the carrier lug with the larger material portion of the second Carrier element is located.
  • the two carrier element are not congruent, but opposite, arranged to each other.
  • the two carrier elements are arranged asymmetrically with respect to a plane of symmetry extending between the two carrier elements.
  • This preferred embodiment has the advantage that in the event of failure of one of the carrier tabs, the pin on the other carrier tab will continue to hold. Thus, if the first carrier element in the region of the carrier lug breaks without the greater proportion of material, then the pressing element continues to hold in the second carrier element, specifically in the carrier lug with the larger material content. Thus, flying away of the pressing element is largely prevented.
  • each bolt extends through a carrier tab, which is provided with the larger material portion and by another carrier tab, which is formed without the larger proportion of material.
  • two spaced-apart support elements are arranged, wherein only one of the two support elements is formed with the said larger material portion.
  • said larger material content of the carrier element in the region of a carrier lug with respect to an axis of symmetry is formed asymmetrically to the material portion of the carrier element region of the other carrier lug.
  • the two carrier tabs are therefore formed asymmetrically with respect to the axis of symmetry.
  • the axis of symmetry extends at right angles to a straight line connecting the two pivot axes, wherein the axis of symmetry preferably lies centrally between the two pivot axes.
  • the straight line runs at right angles to the pivot axes.
  • the axis of symmetry can also extend at an angle to the said straight line.
  • the axis of symmetry passes through the two pivot axes and at right angles to it.
  • the said larger proportion of material of a carrier lug with respect to a plane of symmetry is formed asymmetrically to the material portion of the other carrier lug.
  • the plane of symmetry in a variant runs at right angles to a straight line connecting the two pivot axes and parallel to the pivot axes, wherein the plane of symmetry preferably lies centrally between the two pivot axes.
  • the straight line runs at right angles to the pivot axes.
  • the plane of symmetry may also run at an angle to the said straight line.
  • the plane of symmetry passes through the two pivot axes.
  • the plane of symmetry runs at right angles to the two pivot axes centrally through the carrier lug without a large proportion of material.
  • the larger material content is greater by at least 1%. This means that the carrier lug with the larger material content has 1% more material than the carrier lug without the larger material content.
  • the larger proportion of material is arranged on an outer surface of the carrier lug, which outer surface is preferably substantially parallel to is oriented to the pivot axes.
  • the larger proportion of material is arranged exclusively on an outer surface.
  • the larger proportion of material is arranged on a front surface of the carrier lug, which front surface preferably extends substantially at right angles to the pivot axes.
  • the larger proportion of material is arranged exclusively on a front surface.
  • the larger proportion of material is arranged on an outer surface of the carrier lug and on a front surface of the carrier lug.
  • the outer surface is preferably oriented substantially parallel to the pivot axes.
