Definitions
- the invention relates to a cutting disc with the features in the preamble of the main claim.
- Such a cutting disc is known from EP-A-0 836 903 known. It is a diamond disc for cutting Stones, concrete and other hard handicrafts designed and has a rotationally driven Disc body with several cutting segments on Outer circumference.
- the inside of the window body has one Variety of breakthroughs that are different Can have shapes.
- the breakthroughs are in a regular geometric grid on the Distributed disc area. Here they are either in rings arranged centrally to the central disk axis or arranged in biaxial linear geometric grids.
- the invention solves this problem with the features in the main claim.
- the spiral or vortex-shaped arrangement of the openings has advantages in the heat dissipation and in the noise development of the rotating cutting disc.
- the arrangement of the openings in side-by-side spiral lines, which bulge in particular in the direction of rotation of the cutting disc, ensures a particularly quiet cutting disc with optimal air cooling.
- the cutting disc is therefore dry cut.
- the cutting disc works with a grinding Removal and is suitable for different, hard Materials, e.g. for concrete with and without reinforcement, for Roof tiles, for hard and medium hard clinker, for Washed concrete and for general construction material.
- the cutting disc (1) shown in Figures 1 and 2 is preferably designed as a so-called diamond disc and serves to cut and cut hard materials, like stone, concrete or the like.
- the cutting disc (1) can in a suitable manner about its central axis (2) in Drive direction of rotation (11) rotationally and carries in Cut off the material.
- the cutting disc (1) can be used for dry cutting, is suitable but also for wet cutting.
- the cutting disc (1) has a cylindrical one Disc body (4), one on its outer circumference (14) Cutting ring (13) carries.
- the cutting disc is in the center (1) a preferably circular receiving opening (12) for Attachment to a drivable shaft or the like.
- the disc body (4) has a variety of Openings (5) with a preferably circular one or cylindrical shape.
- the openings (5) are with mutual distance evenly distributed and in one Spiral shape (6) or vortex shape on the disc body (4) arranged.
- the spiral shape (6) can vary be trained.
- the Breakthroughs (5) a variety of similar Spiral lines (7) from the area of the disc center axis (2) go out and to the outer edge (14) of the Extend the disc body (4).
- the spiral lines (7) are in the circumferential direction side by side with regular Distribution arranged.
- the internal openings (5) of the spiral lines (7) form one with the other Central axis (2) concentric inner bolt circle (8). Of this the spiral lines (7) go out.
- the mutual distances of the spiral lines (7) in the circumferential direction change with the radial distance. They are the smallest at the bolt circle (8) and enlarge up to the outer edge (14) of the disk body (4).
- the annular cutting ring (13) preferably consists of several cutting segments regularly distributed in a circle (3), with appropriate cutting edges and Cutting surfaces are equipped and in each other Are circumferential distance. Your end faces in The circumferential direction is chamfered.
- the cutting segments (3) are thicker than the disc body (4) and stand on both sides.
- the cutting segments (3) act as Abrasives and are with abrasive particles, e.g. Diamond granules, corundum or the like.
- the cutting segments (3) can be made from a suitable other material than the disc body (4) and are with the outer edge (14) by a Welded connection (10), preferably one Laser welded connection, or in any other suitable way firmly connected.
- the cutting segments have in the foot area (3) at their transition points from one to the other Segment one outwards against the direction of rotation (11) opening undercut (9) into the Edge area of the disc body (4) protrudes and there on End in a somewhat widened and essentially circular opening passes over.
- the spiral lines (7) are preferably in the same number like the cutting segments (3) and such arranged that each spiral line (7) with its outer Opening (5) on the edge of the disc body between the adjacent undercuts (9) ends.
- each spiral line (7) with its outer Opening (5) on the edge of the disc body between the adjacent undercuts (9) ends At a practical embodiment with 230 mm disc diameter are e.g. sixteen spiral lines (7) and a corresponding number Cutting segments (3) available.
- the single spiral line (7) can be about ten to twelve evenly spaced Openings (5) with a diameter of approx. 5 mm.
- the numerical values mentioned are examples and can fluctuate up and down. In particular has a cutting disc (1) with a smaller diameter correspondingly lower number of spiral lines (7) and Breakthroughs (5).
- the spiral lines (7) are preferably in the direction of rotation (11) the cutting disc (1) bulged or bulged. she pass over an angle "a" of each approx. 50 ° to 60 °.
- the angles of curvature of the spiral lines (7) can also be chosen differently depend in particular on the disc diameter.
- the openings (5) ensure the cutting operation of the rotating cutting disc (1) for swirling the surrounding air. On the one hand, this means that at the Cutting disc (1) from the heat generated by the cutting work released to the ambient air and discharged.
- the Spiral shape (6) of the openings (5) and in particular the special design of Figures 1 and 2 ensure this for a particularly good heat dissipation, on the other hand the noise caused by the air turbulence the rotating cutting disc (1) can be minimized. In addition result from the transparency of the company rotating cutting disc (1) Control options for the operator.
- Variations of the embodiment shown are in FIG possible in different ways. On the one hand, they can Cutting segments (3) formed in any other way and be arranged. Likewise, the spiral shape (6) vary. On the one hand, this applies to the number, Arrangement and formation of the spiral lines (7) and on the other hand with regard to the angle of curvature individual spiral lines.
- the shape of the is also variable Openings (5) instead of a circular one Cross-sectional shape also an oval, prismatic and in suitably can have a different shape.

Abstract
Description
Die spiralförmige oder wirbelförmige Anordnung der Durchbrechungen hat Vorteile bei der Wärmeableitung und bei der Geräuschentwicklung der rotierenden Trennscheibe.
Die Anordnung der Durchbrechungen in nebeneinander angeordneten Spirallinien, die sich insbesondere in Drehrichtung der Trennscheibe ausbauchen, sorgt für eine besonders leise Trennscheibe mit optimaler Luftkühlung.
Die Trennscheibe ist dadurch im Trockenschnitt.
- Figur 1:
- eine Draufsicht auf eine Trennscheibe und
- Figur 2:
- einen Partialschnitt durch die Trennscheibe gemäß Schnittlinie II-II von Figur 1.
Die gegenseitigen Abstände der Durchbrechungen (5) innerhalb der einzelnen Spirallinien (7) bleiben hingegen vorzugsweise gleich.
