Definitions

  • the invention relates to a cutting wire guide for cutters according to the preamble of claim 1.
  • Ceramic products such as masonry and roof tiles, are cut from plastic strands with wires clamped between two brackets.
  • the service life of the wires is of crucial importance for the performance of the system. In addition to the tensile strength and the diameter, this also depends on the type of clamping.
  • a cutting wire guide according to the preamble of claim 1 has become known from DE-OS 38 17 583. It is also known to the person skilled in the art to tension the cutting wire over rollers with a guide groove after the clamping.
  • wire guides have in common that the wire swings strongly after it emerges from the strand to be severed, which leads to material fatigue and to the tearing of the wires because the thinnest possible wire must be used because of the cleanliness of the cut.
  • the invention is therefore based on the object of providing a wire guide which reduces the ringing of the wires as they exit the strand and brings about rapid calming.
  • Claims 2 to 10 contain advantageous configurations of the attenuators.
  • the invention considerably reduces the oscillation amplitude and oscillation period of the wires after the strand has emerged, as a result of which a long service life can be achieved and even thinner wires than usual can be used.
  • the formation of standing vibrations between the rigid holders of the wire is largely avoided.
  • FIG. 1 shows schematically the guiding of a cutting wire 1 between the wire holders 2, 2 '(2' only partially shown) with the guide bodies 3, 3 'and the deflection elements 4, 4' attached to them.
  • the deflection members 4, 4 ' are arranged at a short distance from the strand 5 on the guide bodies 3, 3' either fixed or adjustable in the direction and / or across the wire 1.
  • the deflecting elements 4, 4 ' can also be non-illustrated contact elements, which are each movably arranged on the guide bodies 3, 3' and bear against the wire (1) under spring preload.
  • the deflection members 4, 4 ' have circular-arc-shaped grooves 6 through which the wires 1 are guided.
  • the wires 1 run from the deflection elements 4, 4 'in the direction of their holders diagonally upwards at an angle of at most 45 ° to the horizontal. The angle should generally be smaller.
  • the radius R of the curved grooves 6 should be considerably larger than the length L of the deflection elements 4, 4 '.
  • a radius R of at least 150 mm and a length L of at least 50 mm can be used as guidelines, i.e. a ratio of about 3: 1. These dimensions are not binding for the function.
  • the deflection elements 4, 4 reduce the amplitude M of the wires and their period of oscillation, similar to a finger on a guitar side.
