Definitions
- Abrasive blade for arranging on a rotationally driven about a rotation axis
- the invention relates to a grinding blade for arranging on a rotating drivable grinding wheel, which has an outer edge which is at least partially convex, an inner edge which is at least partially concave, a leading edge, the outer edge and the inner edge on a front side of the grinding blade with each other and a trailing edge interconnecting the outer edge and the inner edge at a rear side of the abrasive sipe. Furthermore, the invention relates to a grinding wheel with at least one support element and a plurality of such partially overlapping, together forming a ring shape grinding lamellae. The invention also relates to a pattern for such abrasive slats.
- Such provided with a number of grinding blades grinding wheels are placed on a drive machine to be able to edit grinding workpiece surfaces.
- Such grinding wheels and grinding blades are known in the prior art in various embodiments.
- EP 1 142 673 B1 shows a grinding lamella of the type mentioned in the introduction which has two mutually parallel edges and between these a convex and a concave third and fourth edge.
- the abrasive lamellae are applied like a tile overlapping on an annular support portion of a carrier.
- the object of the present invention is, on the one hand, to propose a sanding lamella which produces minimal waste in its production and, on the other hand, to provide a sanding pad which has a high degree of covering of sanding lamellae in the edge region.
- a grinding blade for arranging on a rotating drivable grinding wheel which has an outer edge, which is at least partially convex, an inner edge which is at least partially concave, a leading edge, the outer edge and the inner edge on a front side of the Grinding blade connects to each other, and a trailing edge, which connects the outer edge and the inner edge to each other at a rear side of the grinding blade comprises, wherein the leading edge is longer than the trailing edge and the outer edge is longer than the inner edge.
- the advantage of the abrasive flaps according to the invention is that the degree of overlap of a grinding plate comprising such abrasive flaps in the edge region, ie where the highest speeds occur during operation of the tool and also the main working zone is maximum. This means that where the main stress lies (at the large diameter), most of the material is available, while where there is only a small contribution to the grinding removal (at the small diameter), also less abrasive material is available. As a result, a long service life of the grinding plate is achieved. This is created by relatively small abrasive flaps that allow for a thicker fluff pack, as required in some applications. Furthermore, the object is achieved by a grinding wheel with at least one carrier element and with a plurality of mutually partially overlapping, together forming a ring shape grinding lamellae according to the invention.
- the object is achieved by a cutting pattern for a material blank or a material strip for producing abrasive wipes according to the invention, wherein the grinding fins are arranged next to each other in rows adjacent to each other, each two adjacent grinding lamellae of a row are rotated 180 degrees to each other and point-symmetrical are formed to each other.
- edges of a sanding lamella refer to the sanding lamella package of a plurality of sanding lamellae according to the invention, wherein the sanding lamella package is arranged annularly on the finished sanding disk.
- the outer edge is thus arranged on the outer peripheral edge of the abrasive lamella packet or of the grinding disc, the inner edge on the inner circumferential edge of the grinding disc packet, the leading edge in the direction of rotation of the grinding disc seen at the front and the trailing edge in the direction of rotation of the grinding disc at the rear.
- the trailing edge is the edge of the individual grinding lamellae visible in the grinding lamella packet and, since it is the machining edge during grinding, is preferably rectilinear.
- the front edge is designed to be rectilinear.
- the outer edge has a convex outer edge section over at least part of its length.
- the inner edge has a concave inner edge portion over at least part of its length, the convex outer edge portion and the concave inner edge portion having the same radius. The latter is important in order to ensure the lowest possible production of the grinding lamellae when they are cut from a strip. This is That is, a convex outer edge portion of a grinding fin at a concave inner edge portion of an adjacent grinding fin.
- the outer edge can be made longer to provide as much abrasive material on the outer peripheral edge of the Schleiflamellenvers available. This can be further improved by a further straight outer edge portion is provided between the convex outer edge portion and a corner in the transition between the outer edge and the trailing edge.
- the inner edge may be formed concave over its entire length with a constant radius such that the inner peripheral edge of the abrasive disc pack is circular.
- the abrasive flaps are preferably bonded to the carrier element, for example by a resin.
- the trailing edges of the grinding blades are preferably arranged radially relative to the axis of rotation.
- the abrasive flaps are also preferably configured such that an angle enclosed by the leading edge and the trailing edge of the abrasive flaps is greater than an angle subtended by an imaginary radius referenced to the axis of rotation through a corner between the inner edge and the leading edge extends, trapping the trailing edge. This also ensures that more abrasive material is available on the outside.
- the outer edges of the abrasive flaps are preferably arranged on the carrier element such that they form an outer peripheral edge of the abrasive wheel.
- the carrier element is preferably dish-shaped and can be made of a metal, a resin-bonded glass fiber fabric, a fiber material or a plastic material, in particular vulcanized fiber.
- the support member has an annular edge portion for attachment of the grinding blades and an inner hub portion, wherein in the hub portion, a bore for attachment of the grinding wheel to a drive machine is provided.
- the pairwise 180 degree twisted arrangement of two adjacent grinders of a herring of the pattern and the point symmetric design of the abrasive slats allows all the abrasive slats to be identically shaped and multiple rows can be cut side by side from a band of abrasive material without any wastage between rows or between adjacent ones Abrasive blades of a series arise.
- the cutting pattern is preferably designed such that in each case two adjacent grinding lamellae which abut each other with their trailing edges form two marginal edges of the row, the marginal edges each having a concave edge region and a convex edge region, between which straight edge regions are provided. Furthermore, each marginal edge may each form the inner edge of one of the two adjacent abrasive flaps and the outer edge of the other of the two adjacent abrasive flaps.
- FIG. 1 is a plan view of a grinding blade according to the invention
- Figure 2 shows an inventive pattern
- FIG. 3 shows a grinding wheel according to the invention.
- Figure 1 shows a plan view of a grinding blade 1 according to the invention with an outer edge 2, an inner edge 3, a front edge 4 and a trailing edge 5. Die Designations of the edges 3, 4, 5, 6 of the grinding blade 1 are derived from the arrangement of the grinding blade 1 on a support member 15 of a grinding wheel 19. The outer edge 2 is thus arranged on an outer peripheral edge of the grinding wheel 19, the inner edge 3 faces inwardly to a hub portion 18 of the support member 15, the leading edge 4 is arranged in the direction of rotation D of the grinding wheel 1 about the axis of rotation front and the rear edge 5 according to the rear.
- the outer edge 2 has a plurality of sections / regions, wherein a straight outer edge section 7 extends from a first corner 6 between the outer edge 2 and the front edge 4. This is followed by a convex outer edge portion 8, which is followed by a straight outer edge portion 9 which terminates at a second corner 10 between the outer edge 2 and the trailing edge 5.
- the inner edge 3 is over its entire length, d. H. formed between a third corner 1 1 between the front edge 4 and the inner edge 3 and a fourth corner 12 between the trailing edge 5 and the inner edge 3 is completely concave.
- the entire inner edge 3 thus forms a concave inner edge portion.
- the leading edge 4 and the trailing edge 5 are both designed to be straight along their entire length.
- the front edge 4 is designed to be longer than the trailing edge 5, wherein the front edge 4 and the trailing edge 5 form an angle to each other, which is open to the outer edge 2 out.
- FIG. 2 shows a band 14 made of an abrasive material which extends in the direction of the arrow P and on which the pattern for producing the abrasive lamellae 1 from the band 14 is shown.
- the cut-out grinding blades 1 are arranged next to each other in rows 13 next to each other.
- Each two adjacent grinding lamellae 1 of a row 13 are arranged rotated by 180 ° to each other, wherein two adjacent grinding lamellae 1 abut either with their leading edges 4 or their trailing edges 5.
- the grinding blades 1 are arranged in pairs symmetrically to one another.
- FIG. 3 shows a plan view of a sanding pad with abrasive flaps 1 according to the invention.
- the individual grinding blades 1 are arranged partially overlapping in the form of an annular Schleimamellenpaktes on a support member 15 and bonded to the support member 15.
- the support member 15 has a likewise annular support portion 16, on which the abrasive slats 1 are glued.
- the carrier element 15 has an inner hub portion 18, in which a bore 17 is provided, by means of which the grinding wheel 19 can be attached to a drive machine.
- the leading edges 4 of the grinding lamellae 1 are arranged concealed under the subsequent grinding lamella 1.
- the trailing edge 5 is visible and limits the working range of the grinding blade 1, which can be used on the front side.
- the trailing edge 5 is in this case arranged radially to a rotational axis D of the grinding wheel 19. In principle, however, it is also conceivable that the trailing edge 5 deviates slightly from an imaginary radius to the axis of rotation D.
- the leading edge 4, however, is not arranged radially to the rotational axis D but at an angle such that the angle between the leading edge 4 and the trailing edge 5 is greater than if the leading edge 4 were arranged radially.
