Definitions

  • the present invention relates to a cutting device for cutting thermally processable material according to the preamble of claim 1.
  • Such a cutting device is from the DE-GM 83 26 687 known.
  • This device Cutting frame with the same weight at a distance from each other arranged one inside the other.
  • the outer cutting frame is driven by an eccentric drive an oscillating movement.
  • This swinging motion is through the coil springs on the inner frame transfer.
  • So cutting frames are different Size provided despite different Material requirements must have the same weight, i.e., that the inner cutting frame must be made heavier when it was manufactured according to the strength values could.
  • the cutting elements have the outer Cutting frame a longer length, although only foam blocks can be cut, the dimensions of which inner, smaller cutting frame is limited. Corresponding the large material masses are also sufficiently large drive units and operational power systems necessary.
  • the oscillating movement serves the Cutting wires during the cutting process due to the resulting Heat friction so much that the foam material of the foam block in the cutting plane melts and the Block is cut thereby.
  • the object of the present invention is to be achieved are, a cutting device of the type mentioned To be designed so that an oscillating movement of the Cutting wires in a simpler and cheaper way can be done as this with the beginning described device is possible.
  • a cutting device of the type mentioned To should also be made possible with cutting devices electrically heated cutting wires as smooth as possible and as few open pores as possible To reach the cutting surface.
  • the invention is particularly characterized in that only small masses in motion for the cutting process must be set. As a result, will only be comparative small drive units and energy supply systems needed. Also the foundation for the invention The device can be designed to be less resilient become.
  • a cutting device with electrically heated Cutting wires is the cut surface at least in the View smoother and less porous than that of the Processing with the known cutting devices.
  • the cutting speed can be increased.
  • 1 is a first and 2 is a second side member designated, the distance 3 parallel to each other on one Frame beams 4 and 5 of a cutting frame of a cutting device for cutting or cutting blocks, in particular Foam blocks, made of thermally processable Material such as polystyrene are attached.
  • Each longitudinal beam 1, 2 preferably has two linear guides 6.1 or 6.2, each with an adjustment slide 7.1 or 7.2 longitudinally adjustable and positionally adjustable is.
  • the adjustment slides 7.1., 7.2 are driven electrically, for example via servomotors, or pneumatic or hydraulic.
  • longitudinal beams 1, 2 are also parallel to each other and to the longitudinal beams 1, 2 arranged longitudinal sliding guides 8.1, 9.1 or 8.2, 9.2 attached.
  • longitudinal sliding guides 8.1, 9.1 or 8.2, 9.2 attached on these are a plurality of, for example, 30 to 150 Wire guides 10.1 and 10.2 guided in a longitudinally displaceable manner by suitable means in one by means of the adjusting slide 7.1, 7.2 adjusted longitudinal position or position adjustable.
  • the adjustment of the wire guides 10.1, 10.2 is carried out by means of the adjustment slide if necessary 7.1, 7.2 each have an electrical, pneumatic or hydraulic coupling element 7.1.1 or 7.2.1.
  • the wire guides 10.1 of the longitudinal beam 1 each have one Wire holder 11.1 and the wire guides 10.2 of the side member 2 each have a wire holder 11.2.
  • the wire holders 11.1, 11.2 are as rocker arms 11.1 and 11.2 formed by a parallel to the longitudinal beam 1 or 2 extending pivot axis 12.1 or 12.2 pivotable are stored.
  • the rocker arms 11.1, 11.2 have at the foot end slightly inclined stop surfaces 11.1.1 and 11.2.1, that limit the swivel range of the rocker arms 11.1, 11.2.
  • the rocker arm 11.1, 11.2 At the head end 11.1.2 or 11.2.2 of an arm 11.1.3 or 11.2.3 the rocker arm 11.1, 11.2, the angle ( ⁇ ), in particular at right angles to that through the side members 1, 2 spanned virtual level 13 is one end 14.1 and 14.2 of a cutting wire 14 attached.
  • the longitudinal axis 14.3 of the cutting wire 14 runs parallel to the virtual plane 13 formed by the longitudinal beams 1 and 2 from one rocker arm 11.1 to another rocker arm 11.2.
  • the Rocker arms 11.1 of the side member 1 are each one Spring element 15 biased such that the cutting wire 14th is excited. The cutting wire 14 is thus through the pivoted rocker arms 11.1, 11.2 against Force of the spring element 15 in the direction of its longitudinal axis 14.3 can be moved back and forth.
  • Eccentric drive 16 is via a joint 19 on a lever 20.1 a rod 20 running parallel to the longitudinal beam 2 articulated, which is also parallel to the side member 2 extending axis 21 is pivotable.
  • the rod 20 has one over the entire adjustment range the rocker arm 11.2 along the longitudinal sliding guides 8.2, 9.2 extending cams 20.2.
  • the cam 20.2 is in Operating position of the eccentric drive 16, for example on Arm 11.2.3 of all rocker arms 11.2 or, as in the embodiment shown, on a special lever arm 11.2.4 the same.
  • This eccentric stroke causes a back and forth movement of the cutting wire 14 corresponds to the cutting stroke 22 of the cutting wire 14 the adjustment angle ( ⁇ ) of the rod 20 and its cam 20.2 according to the eccentric stroke directly or, depending on the choice of Length and arrangement of the lever 20.1, reduced accordingly or enlarged.
  • the eccentric drive 16 thus forms together with the rod 20 and its cam 20.2 a cam drive for the cutting wire 14 and thus also for everyone on the longitudinal beams 1, 2 existing wire guides 10.1, 10.2 with their rocker arms 11.1, 11.2 and their cutting wires 14 so tensioned.
  • rocker arms 11.2 common Cam 20.2 can also be used for each rocker arm 11.2 these individually assigned cams are present, whereby then these cams according to the possible adjustment of the Rocker arm 11.2 to adjust the position of the cutting wires 14 must be adjusted with.
  • a cutting device using electrical heated cutting wire is a longitudinal sliding guide 8.1 or 9.1 or 8.2 or 9.2 of the side members 1, 2 as Conductor rail formed over which the heating wires the heating voltage can be supplied.
  • the feeding of the Heating voltage is preferably via the respective wire guide 10.1 or 10.2 and the wire holder or the rocker arm 11.1 or 11.2.
  • the cutting wire frequency is advantageously about 20 Hz up to 100 Hz, in particular about 40 Hz.
  • the cutting wire stroke 22 is about 5 mm to 30 mm when used in systems with electrically heated cutting wires 14 preferably about 5 mm to 15 mm, in particular about 10 mm.
  • the operation of the cutting device according to the invention is the following:
  • the foam blocks to be cut are in this operating state by the cutting frame transported and - if desired - under heating of the Cutting wires 14 cut. It is also possible to do that too cutting foam blocks to fix and To move the cutting frame, the cutting wires 14 through to be pushed through or through the foam blocks.
  • the eccentric drive 16 switched off and, if necessary, to reset the Cutting wires 14 pivoted into the position in which the Cam 20.2 out of operative connection with the rocker arms 11.2 is.
  • the cutting process can be carried out again in the specified manner.
