Definitions

  • the invention relates to a device for biasing a machine frame with a tie rod comprising a first and a further anchor head for placing on the machine frame and comprising a tension member for receiving tensile forces between the anchor heads, wherein the tension member extends along a tensile length of the tie rod.
  • the invention also relates to a machine frame having an upper crosshead and a lower crosshead for receiving machining forces introduced into the machine frame, with frame elements for spacing the crossheads from one another and with at least one tie rod acting between the crossheads, wherein the tie rod has a tension element and two anchor heads having the ends of the tension element and wherein the tie rod is mounted by means of the anchor heads on the crossheads.
  • the invention relates to a pressing or pulling device with a machine frame and with a device for biasing the machine frame.
  • Pressvornchtungen in which between a head and a subordinate one hand only on train claimed clamping rods and on the other hand pressure-resistant spacers are arranged.
  • each of the high-strength steel wires extends once from the crosshead to the lower beam.
  • the individual high-strength steel wires of the tendon are easier to handle than a tie rod with a solid steel column. In this respect, the disadvantages of column-type press racks can be avoided.
  • a tie rod consists of a prestressed sheath of individual bands or wires.
  • the pretensioned jacket is placed around a yoke and around supports of the press frame and in the foot area of the press frame are the individual bands or wires each anchored in the press frame, whereby the prestressed jacket holds the press frame together.
  • each of the individual bands or wires passes once around the yoke.
  • the prestressed jacket absorbs the machining forces acting in the press, thereby relieving the other frame components.
  • the machine frame consists of a core storing the clamping forces and a cladding construction homogeneously connected to this core, wherein a winding of the high-strength steel wire or strip generating the tension in the press body lies between the core and the cladding construction.
  • the winding holds together here a lower part and an upper part of the press body by being biased accordingly.
  • tensile and bending stresses can be absorbed in the machine frame of prestressed concrete.
  • the prestressed concrete machine frame is very heavy, making it unsuitable for large presses.
  • the press frame has a clamping device with a plurality of individual clamping elements, which are each stored or anchored with suitable anchoring elements on the upper spar and on the lower spar. At least one of the spars has an arcuate Umschlingungsauflager on the clamping elements.
  • the clamping elements may be monofilament prestressing steels in the form of round steel or strip steel or tensioning cables constructed therefrom. Each of the tensioning cables is guided from a first anchoring element to a second anchoring element, wherein the respective tensioning cable is deflected at one of the spars.

  • By using and guiding the tensioning cable can be dispensed with massive steel columns.
  • the installation of the press frame on site designed relatively complex because the tensioning cables must be guided through the complete press frame. This is quite difficult for large presses with correspondingly large-sized tensioning cables.

  • a particularly noteworthy advantage is the fact that when tensioning the tie rods or the pretensioner per tie rods only a single tension element needs to be biased, which significantly simplifies the assembly effort. This is particularly advantageous with regard to machine frames with a dimension of several meters in height. It is understood that, if necessary, more tension elements can also be provided per tie rod, so that the aforementioned advantage is reduced but nevertheless noticeably present.
  • tie rod in the present case describes any devices that are used in machine frames to accommodate tensile stresses within a machine frame. Such tensile stresses arise within the machine frame, for example, by pressing pressures on presses. It is understood that the tie rod may also include pressure bar or push rods or may be suitable to absorb pressure forces or other forces. However, these are not mandatory in the present case, since such printing devices are ideally provided by a machine frame. In this respect, the structure of the present biasing device or the tie rod further simplified.
  • tension element encompasses any devices which can, however, absorb tensile forces only to a limited extent or only under pressure.
  • a pulling element consist of wires. This already follows from the fact that the device for direction reversal requires a corresponding bending of the tension element, wherein any devices that are correspondingly bendable, are accordingly unstable against compressive forces or other forces that are not tensile forces.
  • the tension element is designed as a traction cable, in particular as a steel cable.
  • the tension member may be a rod, for example a steel rod, or even a band, for example a narrow sheet, e.g. made of steel.

  • the anchor head needs to be rotated after passing through the implementation of the support only about 90 ° about its vertical axis and stored on the support to be mounted on the machine frame quickly and easily.
  • a rotation of the anchor heads can also be superfluous, if between the anchor head ends of an anchor head and the support corresponding support brackets are placed, by means of which the implementation can be bridged.

  • two attachment means of the tension member may be attached to the means for receiving.
  • Such a fastening device may be, for example, a wedge lock, a thimble, a forked cable sleeve or the like at the ends of the traction element.
  • both ends of the tension element can be fastened to only one of the two anchor heads. This may cause an assembly of the tie rod or simplify maintenance work on the tie rod, since appropriate attachment work must be made only on one of the two anchor heads.
  • a related advantageous embodiment provides that the anchor heads of the tie rod are designed asymmetrically.
  • the structure of the tie rod can be further simplified if the tension element is alternatively designed as Endloszugseil.
