Definitions
- the invention relates to abrasive flap discs.
- Abrasive discs can come in different forms. We can in particular, without limitation, store them in three categories.
- the most common discs are those made of materials belonging to the family of conventional abrasives applied, namely a superimposition of generally three elements: a support, more or less rigid, on which is laid a layer of abrasive particles secured to the support by at least one, and generally two layers of binder. These materials are then cut to the desired shape, generally circular, and pierced in the center with an opening allowing them to be fixed by clamping to the axis of the tool, directly, or through a rigid part if the support is flexible, rigid part sometimes designated under the name Anglo-Saxon "backing plate" or "pad”.
- discs consist of a generally rigid support which is provided at its periphery with a working area where hairs are distributed or brushes, for example metallic, in particular so that the plane passing through the work area is substantially parallel to the plane disc, or perpendicular to the axis of rotation of the disc once mounted on the tool.
- the selection of the abrasive disc is done appropriately depending on different parameters, including the nature of the material to be ground (wood, polymer material (plastic), composite material, metal, ...) and the quantity of material to be removed.
- the invention therefore aims to improve the design of the discs abrasives, especially to overcome the drawback mentioned above, by achieving to limit the heating of the parts to be rectified.
- the subject of the invention is an abrasive disc according to claim 1.
- disc is understood to mean a part relatively rigid which is adapted to be mounted on a susceptible shaft to be animated with a rotary movement. This term is not limited to forms purely circular. It includes the materials that we associate with rigid parts, in particular for mounting on angle grinders.
- the disc can be flat or curved.
- the term “work area” means the area of the disc likely to come into contact with the workpiece, when the abrasion operation, an area generally extending radially from the edge outside of the disc up to a certain distance from its center: For flap discs, this zone generally extends from the outer edge up to at most 2/3 of the disc radius, area that can be according to a plane raised relative to the plane passing through the center disc in the case of slats.
- the term “active” zone includes the part of the work area actually capable of operating abrasion, as opposed to “inactive” zones.
- the “active” zones are thus those where are localized slats, areas “Inactive” being generally constituted by the very support of the disc, not functionalized and / or by any part attached to the support, passive towards abrasion, but able to participate in the construction of the disk, in particular to keep some of its elements in place constitutive.
- continuous means that in the area considered, that is to say the “inactive" zone of the work zone, the disc has no openings / holes going right through it, on any its thickness.
- the abrasive discs according to the invention do not are drilled only in their center for mounting on the tool.
- the abrasive discs thus defined significantly minimize the heating of the parts during their rectification.
- the area of the workpiece no longer in permanent contact with the means abrasives on the disc as long as the operator exerts pressure of the disc on the part: periodically, the part will be "at rest” during the passage of the inactive area (s) of the working area of the disc, resulting in a less heating.
- the working area of the disc according to the invention is breaks down into a plurality of "active" zones separated from each other others, by one or more of the “inactive” zones.
- the “active” zones must be sufficiently large compared to the entire work area, their surface being chosen according to the desired performance and may vary depending on the applications referred. We therefore prefer that the “active” zone or all of the zones “Active” constitutes 10 to 90% of the work area, in particular 40 to 80%, and preferably 50 to 70% thereof.
- the invention can be applied both to discs whose support is more of a flexible type and should generally be associated with a room rigid for mounting on the tool only to discs whose support is rigid enough in itself to be mounted directly on the tool.
- the abrasive means are lamellae, such as described above, fixed by one of their edges around the perimeter of the disk.
- the support is generally rigid, especially made of plastic / reinforcing fibers such as glass fibers or metal.
- the invention relates to the abrasive discs of the lamella type, preferably having a rigid support pierced with sound center for its assembly, its working area being continuous and comprising a plurality of abrasive-coated lamellae fixed by one of their edges at the periphery of said support and aligned substantially in a circle centered on the axis of the disc.
- more than one of the strips is lacking contact with at least one of the other two neighboring lamellae who are "active", ie actively participating in the function abrasive disc.
- the edge attached to the support of this lamella is separated from the edge of the neighboring active lamella with which it has no contact at a distance at least equal to the height of the lamellae.
- the slats can thus be divided into at least two groups at least two slats each, with a distance between two groups of slats greater than the distance between two slats of the same group at least a factor of 2, especially at least a factor of 4.
- each group of slats have at least five, all inclined to the plane passing through the working area of the disc and arranged so that their abrasive coatings partially overlap, with in particular a ratio (slat height / distance between two slats) in the same group of at least 4.
- At least one of these groups is provided with a so-called wedging means. Indeed, in the usual configuration, the slats are aligned along a circle, each slat coming from support the previous slat and keep it at the desired angle of inclination ("Previous” or “next” refer arbitrarily to the way the slats follow one another in the work area with reference to the direction of rotation provided for the disc).
- each of the "first" lamellae of groups may have to be supported by additional means to be held in position, this medium can be a wedge, index, glue points, regularly distributed and fixed to the surface of the support or forming an integral part of it last, before depositing the slats.
- each group of lamellae comprises a sufficiently large number of lamellae to accept that the first strip collapses, becomes de facto "inactive” in term abrasion but serving as a wedge “in situ” for the other lamellae group, or even for the last lamella of the previous lamella group (neighbour).
- the flap disc according to the invention preferably comprises at least at least part, in particular all of the slats inclined according to a plane making an angle ⁇ of at least 10 °, in particular 15 to 60 ° with the plane going through the work area of the disc.
- the edge of the lamellae opposite the edge fixed to the support makes an abrasive "edge" by which can pass an axis making an angle ⁇ with respect to the radius of the disc.
- This angle may be zero, the axis passing through the edge coinciding with the radius. He can too be non-zero, angle of at least ⁇ 5 °, in particular from ⁇ 5 to ⁇ 25 °. Conventionally, it is positive if the measured angle of the axis passing through the radius edge is in the same direction as the direction of rotation of the disc once mounted on the tool. (An angle ⁇ thus measured chosen negative is advantageous to facilitate cooling by ambient air).
- All the discs according to the invention therefore make it possible to limit overheating during the rectification of the parts.
- they are rather suitable for high rotational speeds, for example at minus 1,000 revolutions per minute (including a maximum of 13,000 revolutions per minute) and for abrasion for material removal.
- FIG. 1 represents a flexible abrasive disc 1, with a diameter about 15 cm, with a canvas support 2 primed so suitable, partially covered with an abrasive coating 3 comprising a layer of phenol-formaldehyde binder, then a layer of grains in zirconium oxide and finally a second layer of binder similar to the first.
- This disc is pierced in its center with an orifice 4 intended for its mounting by clamping on the axis of a tool.
- the work area extends from its periphery, here circular, up to a certain distance from the mounting orifice, according to a circle represented by dotted lines.
- the bravery area presents so here a substantially annular shape.
- the "active" zones 5 are in relief, in the sense that the support has been deformed so as to raise these zones compared to the inactive zones of a given height (deformation by stamping discs after cutting, for example).
- the sum of the areas of the active zones 5 corresponds to approximately 60% of the complete work area including the "active" areas and areas "Inactive".
- This disc works in association with a rigid support in reinforced plastic, in known manner, if necessary of suitable shape for take into account the relief of the disc on its rear face.
- the part to be grinded is periodically at "rest” during passages over inactive zones 6, thus limiting friction and therefore the resulting heating.
- FIGS. 2 and 3 describe the preferred embodiment of the invention, namely a flap disc distributed in different groups.
- the disc shown includes a rigid nylon support 11 reinforced with plastic composite with a depression centered on its orifice central assembly 10.
- This flat support area covered by the slats, shaped approximately annular, constitutes the working area of the disc.
- lamellae are made of a flexible abrasive material of the type of that constituting the flexible disk of figure 1.
- the diameter of the support is about 10.5 cm.
- the slats are L 25 mm wide, h high 17 mm and thickness e of approximately 0.5 mm. They are inclined at an angle ⁇ about 35 to 40 ° from the plane passing through the work area.
- the abrasive edges 12 of each of the first lamellae x1 of the groups of slats are along an axis offset by an angle ⁇ of about -10 ° relative to at radius R passing through the fictitious center O of the disc (it is negative, according to conventions described above taking into account the direction of rotation of the disk).
- the slats are distributed in four groups g1, g2, g3, g4 of approximately 15 to 18 lamellae, making a total of fifty lamellae (if they were all contiguous, and overlapping continuously, as is known, there would be approximately 80).
- groups g1, g2, g3 and g4 have not been shown, the dotted lines around the periphery of disc symbolizing the lamellae not shown. The arrows indicate the direction of rotation of the disc once mounted on the tool.
- each strip 13 (its edge which is attached to the support) is a distance measured by following the circumference of the disc d1 about 2 mm from the base of the adjacent lamella x2.
- the base of the first lamella x1 of each group is distant from the base of the last lamella of the previous group x3 by a distance d2 measured in depending on the circumference of the disc about 30 to 50 mm.
- the first strip rests on a wedge 14.
- These shims are distributed and fixed to the support before adding the slats (Au instead of being reported, we can also provide that the support itself is locally deformed appropriately). It may be only one excess glue. They are optional: when the slats in each of the groups are sufficiently numerous, the first lamella, which cannot rest on the previous lamella, can tend to collapse and become "inactive" vis-à-vis the abrasive effect. However, it will allow to prevent the fall of the following ones, which then serves as a hold. In operating on the tool, this household disc, in zones i of the periods of rest limiting overheating.
- the invention thus offers a solution to the known problem of bluing of metallic parts rectified by this type of disc slats, and in a relatively simple way: the support remains unchanged (or almost unchanged if shims are required), the abrasive material remains in the form of lamellae known per se. Only changes their distribution, which can take a wide variety of forms not limited to those shown in FIGS.
- the disc according to the invention "consumes" less abrasive means, and can even some applications, reduce the time required for this work.
