Definitions
- the invention relates to a rotationally drivable Machine grinding tool consisting of one Carrier body, which by means of connecting elements to a Machine drive can be used and the at least one can be brought into contact with a workpiece to be ground Has a work surface that is equipped with abrasives.
- Grinding disks are known. Their working surfaces are usually equipped with abrasive cloth which serves as an abrasive. All surfaces of a disc can be used as the working surface which, when the disc rotates, are moved around the center of rotation of the disc with sufficient peripheral speed for grinding of the grinding wheels at the highest, so that surface areas located there are mostly equipped with grinding lines and the so-called Work surfaces "there.
- the work surfaces can be used to grind profiles of the grinding tools according to the one to be ground Profile be contoured.
- the contoured work surface is stuck with abrasive cloth that is so thin that it can be nestled into the contours. Used up Grinding lines must be removed from the grinding tool regularly loosened and re-glued on abrasive cloth be replaced.
- Grinding tools are included for each profile appropriate contouring is required, with several prepared and contoured grinding tools are to be provided simultaneously to the grinding process same workpieces not with long set-up and Interrupt downtimes and therefore inexpensive to have to burden.
- the invention is based on the object to provide a rotationally drivable grinding tool, that can be used universally and economically for any grinding work on workpieces, in particular Workpieces with a profiled surface, such as turned workpieces, profile strips or the like.
- the carrier body is designed as a disc, the is so thin, e.g. 1 mm that they are transverse to Disc level can spring elastically and in Disc center an approach to the fasteners and that the abrasive is a flat structure with one side with abrasive cloth, sandpaper or the same abrasive layer coated elastic Upholstery layer is, which, in the manner of a surround the outer edge of the disc with which Padding layer is attached to the support body.
- the formation of the carrier body as a disc has the Advantage that the support body at transverse to the plane of the disc pressure forces during grinding can yield resiliently. This enables an advantageous one soft grinding. In addition, this property of soft grinding also further promoted in that Carrier body or the disc grinding lines attached which is a cushion layer on its underside having.
- this cushioning layer both the two, about disc surfaces radially to the center of rotation, at least in the area of the periphery of the disc, as well the outer edge or the outer edge of the plate-shaped, as a disk or plate present carrier body in the Surrounding type of surround can also in essential radially acting pressure forces from the Cushion layer are cushioned, so that even with the narrow radius of the wrapped around the edge or the edge Sanding relatively aggressive, but without Chatter marks and without excessive friction heat builds up, especially at the bottom narrower and deeper Profiling of the workpieces, soft grinding.
- the grinding tool is advantageously relatively flat, so it is suitable to narrow grooves and punctures, as they are especially with wood turning parts or Turned parts made of metal and copper materials occur grind.
- the grinding tool according to the invention can for Grinding work is used, for which so far Contoured grinding wheels were required so that now a universal grinding tool is present.
- the abrasive is a flat structure that means a section or part of a band, a plate, a sanding sheet or similar raw or Starting element that is a layer Abrasive cloth or sandpaper according to desired Has grit on one side, the non-abrasive Back, equipped with an elastic padding layer is.
- the cushion layer is advantageously a foam appropriate porosity and elasticity. Not to them abrasive surface of the back, for example one Sanding, the upholstery is laminated or is the cushion layer with the surface of the back firmly connected, for example in that the foam foamed directly on the back of the sanding line is.
- the cushion layer has a thickness of approximately 1 to 5 mm, preferably 2.5-3 mm. Thinner upholstery layers can be easily pushed through with high sanding pressure, i.e. they can pierce locally, which means that the advantages of soft sanding are lost. On the other hand, thicker cushion layers have the disadvantage that they stretch or stretch excessively due to centrifugal forces, which can lead to undesired changes in shape and, under certain circumstances, detachment from the carrier body. A thickness of the cushion layer of approximately 2.5 mm and an open-cell plastic foam with a compression hardness of 10 - 60 and a density of 17 - 40 kg per m 3 have proven effective.
- a grinding tool in which the carrier body is also designed as a disc that is so thin is that it can spring elastically across the plane of the disc and those in the disc center an approach for that Has fasteners on rotating parts of a machine drive are present and that with the An abrasive that can be combined with a carrier body is a Ring body made of elastic material in the area its periphery with abrasive cloth, sandpaper or the same abrasive layer is provided and the Carrier body is attached.
- Carrier body and ring body together form one unit usable as a grinding tool attached to a Machine drive is attachable.
- the disk serving as the carrier body is in both Solutions according to the invention advantageously as a disc ring trained because the inner hole of a disc ring as Approach for fasteners can serve.
- the Hole edge of the inner hole for example, corresponding Have material reinforcements or thickenings that to recordings for clamping elements Fasteners can be formed, with which the Grinding tool on or on one through the inner hole extending, or protruding into the inner hole Shaft, a hollow cylinder, a bushing or a pin of a machine drive can be tensioned.
- the approach of the carrier body is a short e.g. 7 mm long sleeve formed, the disc about a radially protruding from the sleeve about 10 mm wide Collar flange corresponds.
- Form sleeve with collar flange thus the carrier body, which is identified by means of the sleeve Approach a wave easily, quickly and easily Hollow cylinder, a socket, a pin or the like rotating part of a machine drive is stuck and because of the sleeve also centered sufficiently precisely is.
- the configuration of the carrier body is like this hit that the corresponding to the disc Collar flange, based on the length of the sleeve, sits off-center on the sleeve.
- the inner surface of the sleeve can be radially inward protruding drivers that are in corresponding grooves e.g. the as a hollow cylinder, socket or the like present connecting elements or directly in the shaft or a journal of the machine drive intervene and ensure that the Ensure grinding tool.
- the sleeve and collar flange are particularly advantageous as a one-piece plastic injection-molded part.
- the sleeve and collar flange have roughly the same wall thickness and can be manufactured inexpensively from plastic in large quantities using the injection molding process.
- Other materials for the carrier body for example sheet metal, are possible.
- the collar flange has been edged with the padded abrasive, there is a cheap grinding tool that can be used universally for many grinding jobs and can be easily replaced after the abrasive layer has worn out.
- Worn grinding tools of the type according to the invention do not require reprocessing, as is the case with profiled grinding tools, but can also be completely disposed of.
- the grinding tools according to the invention are thus so-called Disposable Parts ".
- the plastic used to form the carrier body is, with particular advantage, a glass fiber reinforced polyamide.
- the glass fiber reinforcement produces the necessary strength despite the thin-walled design of the carrier body, but allows the desired resilient properties of the collar flange itself, i.e. also the yielding of the entire disc with appropriate pressure on a workpiece to be ground.
- a polyamide has the additional advantage that this material can be dissolved with formic acid, so that dissolved areas can act like an applied adhesive. As a result, after wetting the surfaces of the collar flange with formic acid, the abrasive with its cushioning layer or the alternatively provided ring body can be connected to the carrier body without any problem and without additional use of special adhesives.
- the cushion layer is an open-cell foam with which the detached material of the carrier body can bond particularly intensively and firmly, since the detached material can penetrate into the pores of the foam and for anchoring on the other side ensures as soon as the solvent evaporates and the Adhesive "has dried.
- the one intended as an alternative abrasive Ring body consists of a plastic foam, preferably polyurethane foam of predetermined hardness.
- the abrasive can be attached simply be designed so that the abrasive is in shape a predetermined, for dimensioning the Carrier body or the ring body in each case matching Blank is present. Cuts can be prepared and provide around the carrier body or ring body to equip with it. From plates, tapes, strips or the same raw material of the abrasive can be manufacture the corresponding blanks without further ado. Conveniently, everyone is directly on the carrier body attachable cut a flat, essentially round Stamped part with wedge-shaped edge cuts or Notches.
- edge incisions or notches make it possible to cut the abrasive according to Art an edging wrinkle-free around the outer edge of the Washer or the collar flange or to the curved Lay the work surface of the ring body.
- a hole is arranged in the center of the blank, the Diameter about the same, but not less than that Outside diameter of the approach of the sleeve Carrier body is. The hole in the center of the blank thus hinders attachment of the grinding tool a shaft or a clamping pin of a machine drive Not.
- the outer diameter of the ring body is so dimensioned that its outer peripheral surface the outer edge of the collar flange of the support body around pre-determined dimension and that the carrier body area of the outer peripheral surface of the Ring body has the abrasive layer. Because the ring body consists of elastic plastic foam, it forms a for the grinding behavior advantageous cushion, the the outer dimensions of the carrier body are outstanding Regions of the ring body even more advantageous Way can give way to an increased grinding pressure, because such protruding or outstanding areas of the somewhat stiffer collar flange of the carrier body to be supported excessively.
- a region facing away from the carrier body can be a fillet or similar profile be, which in turn has the abrasive layer. Fillets with different radii and varying dimensions of the bevels allow inexpensive provision various, universally usable grinding tools.
- the grinding tools can be operated with machine drives easy and quick connection, as a machine drive one on a drive journal of a machine includes stretchable hollow cylinder, the outer diameter is equal to the inside diameter of the carrier body and on the at least one of a carrier body with a ring body existing grinding tool attachable and by means of a Fixing member is attachable.
- the hollow cylinder also called a bush has a length that allows various grinding tools on the hollow cylinder to line up.
- the mutual alignment and assignment the grinding tools can be taken so that Abrasive tool combinations are formed that the each workpiece to be ground, in particular profiled workpiece.
- With new grinding tools equipped hollow cylinders can be provided, so that a changeover in an advantageously short assembly time is possible. Business interruptions can be on Press minimum.
- Every clamp ring has at least one clamping screw so that it is in Any slide-on position can be fixed on the hollow cylinder is.
- Spacers can be a predetermined distance between two attached to a hollow cylinder Adjust grinding tools.
- Each hollow cylinder has in its peripheral surface at least one longitudinal groove, in each of which one of the Carrier of a carrier body one on the hollow cylinder inserted grinding tool engages positively.
- the Hollow cylinder forms a rotating part of the machine drive and takes the attached body with the abrasive on it.
- spacers in a longitudinal groove rod parts which can be inserted in a form-fitting manner.
- Each Rod part is one of a plastic profile rod cut piece with the desired length.
- In the longitudinal groove of the hollow cylinder can also Engage the clamping screw of a clamping ring.
- Spacers must be relative be dimensioned or dimensioned by what machining is done. For the user of the This means that it has a variety of grinding tools Spacers made with the highest accuracy or - wrestle must be ready, which may be right time consuming and tedious way to get together combine to get the desired distance between two grinding tools on a hollow cylinder adjust.
- the rod parts make it possible in advantageously, a piece of predetermined length cut that off in the longitudinal groove of the hollow cylinder is used. That turns out from the rod part cut piece as too long, it can be easiest Be cut shorter. This measure is everyone relevant craftsmen familiar.
