Definitions

  • the invention is based on a grinding body of a vibratory grinding device for processing surfaces, in particular wooden surfaces, consisting of a carrier part which can move relative to the surface and which carries abrasive material and which has suction channels opening out on a working side for grinding dust extraction by means of an external suction device.
  • Sanding dust accumulates in considerable quantities during sanding work, particularly in the woodworking industry. According to recent knowledge, sanding dust, especially beech and oak wood, is extremely harmful to health and corresponding legal provisions therefore stipulate that sanding dust released should not exceed 5 mg per cubic meter of air in the vicinity of a workplace. Due to their design, these values could previously only be achieved on stationary grinding machines and grinding tools, since these can be totally encapsulated. However, manual grinding also has a significant share in the grinding work to be carried out, which is either carried out with hand-guided grinding tools, in particular vibration grinding devices, or in which the workpiece to be ground is moved relative to a grinding tool.
  • the abrasive material is an abrasive sheet with which the working side of the carrier part is coated.
  • the carrier part is provided with bores which serve as suction channels, and the sanding sheet has punched holes which coincide with the bores in the carrier part when the sanding sheet is applied to the working side.
  • the holes in the carrier part that serve as suction channels can be connected to an external suction device, with the purpose of sucking and removing grinding dust that occurs during grinding through the holes in the sanding sheet into the holes of the carrier part.
  • the invention has for its object to design a grinding wheel so that there is effective grinding dust extraction during grinding.
  • the arrangement of the mouths of the suction channels in recessed first surface regions with respect to the grinding second surface regions has the advantage that workpieces to be ground only have contact with the grinding second surface regions and thus do not touch the first surface regions.
  • the mouths of the suction channels therefore always remain free even during grinding work. Due to the extraction, an air flow can occur which constantly transports grinding dust accumulating on the second surface areas to the free mouths of the suction channels during grinding. A sufficient suction power of the grinding dust is ensured in the grinding wheel according to the invention.
  • Each first surface area having the mouths of the suction channels can be a bottom of a depression in the working side.
  • a bottom of a depression can be provided with one mouth of a suction channel or with several mouths.
  • the depressions can have any dimensions and shapes. Several depressions can also be connected to one another or overlap.
  • the depressions can be trench-like or pit-like.
  • the depressions can surround a grinding second surface area in such a way that grinding dust that is produced must in any case enter the area of a depression and thus an outlet of at least one of the suction channels before the external limits of the carrier part or the grinding body are reached by the grinding dust.
  • the carrier part is preferably plate-shaped.
  • a plate used as a support part can be rectangular, can However, it should also be round and can then be used as a rotating grinding disc.
  • An elastic material, preferably polyamide, is provided as the material for the carrier part, which can be used in different hardnesses.
  • Soft material has the advantage that curved surfaces can be ground without any problems, since the carrier part or the grinding body can easily adapt to the curved surfaces of the workpiece.
  • the grinding performance can also be influenced by different hardnesses of the carrier part.
  • polyamide is a light material, so that a carrier part made therefrom has an advantageous low weight.
  • the grinding body is preferably designed such that an upper side of the carrier part is provided with projecting studs.
  • the depressions which have the first surface areas with the mouths of the suction channels, are formed by a gap existing between two adjacent tunnels.
  • the studs can be formed in one piece with the carrier part. However, the studs can also be attached to the top of the carrier part. In particular, a releasable fastening of the studs to the carrier part is also possible in order to be able to replace studs if necessary.
  • Each stud is designed as an elongated web, web-shaped studs extending to the outer edges of the carrier part. This has the particular advantage that a gap between two adjacent studs also extends to the edge of the carrier part. Since the mouths of the suction channels are arranged in the bottom of the gap, i.e. in the foot region of the adjacent tunnels, air can be sucked in from the edge of the carrier part during the grinding work, which forms a constant air flow, and this air flow entrains grinding dust into the suction openings.
  • Each web preferably has a width of 10 to 40 mm on. Since the tops of the webs form the grinding second surface areas, there is therefore a sufficient surface contact of the grinding body on workpiece surfaces to be ground. The width of the webs also causes abrasion in the form of grinding dust to reach the first surface area relatively quickly during the relative movement of the grinding body and workpiece and can be suctioned off via the mouths of the suction channels.
  • the carrier part has branch channels running parallel to its plate plane.
  • the puncture channels therefore run inside the carrier part parallel to its upper side studded with studs.
  • the studs can extend transversely to the course of the branch channels.
  • the studs can also run parallel to the branch channels or diagonally to them.
  • the branch channels which can be acted upon by negative pressure generated by an external suction device, can be connected very easily to the mouths of the suction channels, in that each suction channel is designed as a branch hole leading to the respective branch channel in the bottom of the gap between two studs.
  • One suction channel or several suction channels can be assigned to each branch channel, since each branch channel crosses gaps between adjacent tunnels several times and in the crossover area, a branch hole can be made in the bottom of the gap into the branch channel in order to produce the suction channel.
  • the suction power can be influenced as desired by arranging appropriate hole patterns in the tap holes.
  • the number of branch channels and their dimensions also play a role in the suction power.
  • the branch channels are connected to the suction unit directional connecting element connectable.
  • the connecting element connects the branch channels to one another, so that negative pressure generated by a suction device is also distributed over the connecting element to the branch channels.
  • a structurally simple embodiment of the grinding wheel according to the invention provides that the stitch channels open into an end edge surface of the plate-shaped carrier part and that the connecting element is designed as a molded part which can be placed in front of the end edge surface. All branch channels therefore run in the suction direction and form the shortest possible suction paths.
  • the molded part which can be placed in front of the front edge surface connects the branch channels emerging on the front edge surface to one another, with the advantage that the molded part can be kept particularly small in terms of dimensions.
  • a piece of hose made of elastic material as a molded part is particularly advantageous.
  • a simple piece of hose made of soft rubber can be slipped with one end over the rectangular front edge surface of the plate-shaped carrier part, whereby the connection of the branch channels to an external suction device is easily possible by connecting a suction hose line leading from the suction device to the hose piece serving as a molded part .
  • This can be done by simply plugging in the suction hose line, an expansion element being inserted into an end of the hose piece which can be attached to the support part and which facilitates the attachment of a suction hose line brought up by the suction device.
  • the expansion element is designed as a sleeve, which can be made of plastic, for example.
  • An end region of the sleeve facing the carrier part is tapered with particular advantage so that suction hose lines with different diameters brought up by suction devices can be used. By simply plugging them in, suction hose lines of the suction device with smaller nominal diameters become stuck in the conically tapered end region of the sleeve as soon as they are inserted into the sleeve and are held by suction during operation of the suction device.
  • the carrier part has at least one support member protruding into the piece of hose.
  • the support member is arranged so that it angled or deflects the rubber tube piece in its mouth region to the plate plane of the carrier part upwards. Contact with the surface of the workpiece to be ground no longer occurs.
  • the support member can e.g. a bracket anchored to the support part, e.g. be made of metal, which extends like a stick from the front edge surface of the carrier part into the tube piece into the sleeve inserted therein. When the suction device is switched off, the support member also serves to hold the inserted suction hose line.
  • the abrasive material can be sheet-like abrasive cloth or sandpaper known per se.
  • the abrasive cloth or sandpaper can be cut to cover the free top of a stud to be coated with it.
  • One sheet of abrasive material can be held interchangeably on each stud.
  • Suitable fasteners can e.g. Velcro connections.
  • glue abrasive material to the upper sides of the studs, in particular if the free upper sides, which form the abrading second surface areas, are provided with correspondingly incorporated contours for the grinding of profile shapes.
  • a particularly simple design of the grinding wheel provides with particular advantage that second stitch bores leading to an associated stitch channel for the suction holding of the sheet-shaped grinding material open out at the top of each stud.
  • worn abrasive material is very easy to change and is used during of grinding is held by the suction force on the top of each stud only. Worn abrasive material can be clamped or replaced by simply placing it on.
  • the top of each stud is provided with a roughened profile.
  • the profiling can also be formed by applying a rough covering. Profiling or roughening increase the frictional resistance between the top of the stud and the underside of the abrasive material.
  • apron elements each covering the gaps.
  • Apron elements can be formed by rubber strips or bristle rings.
  • Each apron element is preferably designed as a brush protruding from the edge of the carrier part.
  • Such a brush can e.g. B. be made from a rubber strip by providing a longitudinal edge of the strip with a plurality of cuts which form individual rubber bristles. The still coherent other longitudinal edge then offers the possibility of partially fastening such a brush to the edge of the carrier in order to cover a gap between two adjacent studs.
  • the grinding wheel according to the invention is particularly suitable as a special piece of equipment for e.g. Orbital sander. However, it can also be used with a handle, for hand sanding, a conventional vacuum cleaner being usable as a suction device.

  • an expansion element is inserted, which is designed here as a sleeve 16, which is tapered conically in an end region 17 facing the carrier part 1 and ends at the lower end 18 in an inward-facing inner sleeve 19.
  • annular, conically tapering receiving space 20 is formed between the tapering region 17 and the inner sleeve 19, in which a hose end of a hose brought up by a suction device (not shown further) can clamp as soon as it is inserted.
  • each suction channel 24 is a tap hole leading to the respective branch channel 9 in the bottom of the gap 6 between two studs 3.
  • grinding dust enters a gap 6 between two studs 3 in which due to the constantly running suction device, there is also a constant air flow which carries the grinding dust in the immediate vicinity of its point of origin and conveys it through the suction channels 24 and the tap holes 9.
  • Fig. 2 shows how the bracket 14 angled the connecting element upward so that it has no contact with the surface to be ground of a workpiece.
