Definitions

  • the present invention relates to a cutting machine for rigid foam boards with a heated cutting tool which is clamped in a reciprocating frame.
  • the cutting wires are connected in parallel and regulated via a step transformer.
  • this has the great advantage that only small masses are moved due to the large frequency of approximately 25 Hz and the small stroke of approximately 5 mm, and prevents the workpiece from being carried along due to its inertia is, which not only reduces the outlay on equipment, but can also triple the cutting speed due to the lack of friction with a significantly lower power of 0.5 kW. Noise, vibrations and wear are also significantly reduced.
  • the frame and vibrator are mounted on a base frame by means of springs, in particular leaf springs.
  • the tool is electrically resistance-heated in a manner known per se, but the power is controlled via constant voltage, for example by phase control and two stages are provided for preheating and cutting, which are provided by Light barriers are controlled by the workpiece, or regulated in groups to compensate for different heat conduction in the middle or at the edge of the workpiece.
  • the tool can also be formed from resistance wire, which is self-regulating due to the high temperature coefficient, that is to say that it changes the resistance with the temperature in such a way that the electrical power consumed is thereby regulated at a constant temperature, as a result of which different heat dissipation due to density and moisture inhomogeneities in the workpieces be compensated.
  • the tool can also consist of twisted flat wire instead of round wire.
  • FIG. 1 shows the elevation
  • FIG. 2 shows the side view
  • FIG. 3 shows the plan.
  • an oscillating cutting frame 2 and cutting wires 3 are fastened as tools in a fixed base frame or receiving frame 1 and clamped over springs 6, which are electrically heated, by passing a regulated current through them.
  • the oscillating movement of the cutting frame 2 is effected by an electromagnetic vibrator 4 attached to it.
  • the workpiece 7 to be cut in the form of a polystyrene or polyurethane block is then pushed against the cutting wires 2 at an adjustable speed, which cut it into plates, the thickness of which corresponds to the distance between the cutting wires.
