Definitions

  • the invention relates to a cutting device with a pivotally mounted on a frame cutting blade, the cutting edge when cutting into a dip slot between two support beams with a two-sided gap distance between Schneidmesserbreitseite and Tragholmkante dips to push out a strip of material from a lying on the support bars plate-shaped workpiece.
  • Such a cutting device is described by DE 10 2009 003 490 AI.
  • the cutting device has a frame, which consists of two mutually parallel support beams, which are connected at both ends with feet. Between the two beams extends a dip slot.
  • a pivotally mounted between the two support bars cutting blade whose cutting edge has teeth can dip into the immersion slot. It remains between the broad sides of the cutting blade and the slot walls of the immersion slot a gap distance.
  • a cutting blade which dives freely into the slot somewhat eccentrically also centers itself under cutting load as a result of a deformation of the workpiece into the slot, so that the gap spacing on both sides of the cutting blade is approximately the same.
  • Cutting devices of the type described above are also known from FR 575749, FR 612747 A and FR 847014 A.
  • the aforementioned cutting device is provided for the cutting of laminate floor panels.
  • the gap distance between the cutting blade width side and the beam edge is about 2mm to 2.5mm. Such a large gap is required in order to minimize the forces that arise when pushing out a strip of material from the laminate floor panel into the immersion slot.
  • Also known in the market are cutting devices for cutting laminate boards where the gap distance is less than 2mm and which has a cumbersome long handle on the cutting blade.
  • the invention has the object of developing the cutting device to the effect that can be cut on her floor coverings or other plates made of plastic, rubber or other tough or elastic material with sufficiently high quality cut.
  • the cutting edge is provided with a toothing.
  • the distance between the tooth ridges lies in the order of magnitude of the material thickness of the coverings to be cut, ie between 1 mm and 5 mm. Preferably, however, the distance of the tooth ridge is greater than 2mm.
  • the teeth have tooth ridges, which are parallel to the axis of rotation of the
  • Extending cutting blade ie perpendicular to the surface normal of the broad side surfaces.
  • the tooth ridges preferably extend over the entire material thickness of the cutting blade and thus form a blunt cutting edge.
  • the tooth ridges can also be ground so that they run obliquely with alternating oblique direction, so that they enter reinforced at the edge of the cutting strip in the surface of the workpiece. When cut, these teeth dig into the surface of the workpiece to be cut to push the strip of material out of the workpiece plate. It is important if the workpiece is supported on both supporting beams. If thin material plates are to be cut with the cutting device, it is advantageous if the cutting edge transmits reduced horizontal forces into the material plate.
  • a control of the cutting knife is preferably provided, which causes the pivot axis of the cutting blade moves in the course of the carving in the horizontal direction.
  • a control pin assigned in a stationary manner to the carrier beam preferably engages through an arc slot running along a spiral curve in the cutting blade.
  • the slot walls of the immersion slot are formed by an end face of a strip, wherein in each case a strip is attached to a profile rib of a supporting beam. It is further provided that the broad sides of the blade and / or the strips are provided with a non-stick coating.
  • the slot walls are provided with an adhesive coating.
  • the adhesive coating may be a silicone coating or a PTFE (Teflon coating).
  • the coating can be applied as a varnish. It is a coating, as it is in principle already known, for example, from baking pans. With a device designed in this way, adhesive-coated tiles can also be cut. Due to the non-stick coating of the blade and the strips, adhesion of the adhesive is reduced there.
  • the toothing of the cutting blade may be provided with a non-stick coating. In particular, with very narrow slot widths unwanted bonding between the slot wall and Schneidmesserbreitseite or cutting blade teeth is prevented.
  • the device is also suitable for cutting slate plates.

  • FIG. 4 shows a section along the line IV - IV in Fig. 2.
  • Fig. 6 shows the section of Figure 5 with lowered cutting blade.
  • the cutting device shown in the figures substantially corresponds to that described in DE 10 2009 003 490 AI, which is why reference is made to this document with respect to the particular embodiment of the frame, the cutting blade and in particular its storage on the two support bars.
  • the disclosure of DE 10 2009 003 490 A1 is therefore fully incorporated in this application.
  • the drawings show a frame 1, which has two feet 3, which are respectively arranged at the end of two mutually parallel support beams 2 and hold the support beams 2 at a distance from each other.

  • the material thickness of the cutting blade 10 is greater than half the distance between the two slot walls 4, which define the width of the immersion slot 6.
  • the slot walls 4 are formed by strips 5, which are plugged onto dovetail-shaped profiled ribs 7 of the existing aluminum supporting beams 2.
  • FIG. 3 shows that the strips 5 form edges 4 '. These are carrier spar edges 4 ', on which the workpiece 9 to be cut can support. It can also be seen from FIG. 3 that each of the two broad sides 11 of the cutting blade 10 immersed in the immersion slot 6 has a gap distance from the supporting beam edge 4 '. Since the slot walls 4 are parallel to each other, the slot walls 4 have the same gap distance to the broad side 11 of the cutting blade 10, which also has the carrier beam edge 4 '. It can also be seen from the drawings that a rotatable stop 8 is arranged on the supporting bars 2. This stop 8 is essentially an adjustment aid.
  • the joint 15 is formed as described in DE 10 2009 043 992 AI. Then a displacement of the workpiece 9 during the cut is completely prevented.
  • the DE 10 2009 043 992 AI is therefore fully incorporated into this application with regard to the design of the pivot bearing 15.
  • the essential elements of the joint 15 are shown in FIGS. 5 and 6. Although the pivot axis 17 (about which the cutting blade 10 can pivot) is fixedly attached to the cutting blade 10, but displaceable in a horizontal slot 18 of the supporting beam 2.
  • the curved slot 16 extends relative to the pivot axis forming pin 17 on a spiral curve.
  • the pin 17 In the operating position shown in Figure 5, in which the cutting blade is swung up, the pin 17 has the smallest distance to the control pin 19. If the cutting blade 10 is pivoted, the control pin 19 passes through the curved slot 16, wherein the distance between
  • Swivel axis 17 and the control pin 19 increases. This has the consequence that the pivot axis 17 during the cut in the horizontal slot 18, ie in the extension direction of the support beams 2, wanders. For the cut, this has the consequence that the tooth denoted by the reference numeral 13 in FIG. 4 is displaced substantially only downwards, ie in a direction transverse to the direction of extension of the carrier spar 2, during the cut. Thus, no forces directed in the horizontal direction are exerted on the workpiece 9. Even thin-walled workpieces 9 can be cut without causing waves.
  • the usable gap distance range is between 0.5mm and 1.4mm.
  • the teeth 13 dig into the workpiece 9, so that the material strip 9 'pushed out of the workpiece 9 receives a notch on its upwardly pointing side. This notch reduces cut-to-size.
  • the two broad sides 11 of the cutting blade 10 are provided with a non-stick coating.
  • the cutting edge 12 and the teeth 13 may be provided with such a non-stick coating.
  • the strips 5 are provided with a non-stick coating. At least the slot walls 4 and the strips in the region of the upper edge 4 'are provided with a non-stick coating.
  • the non-stick coating may be a silicone coating or a PTFE coating.
