Description

L'invention se rattache au secteur technique des machines portatives à meuler et aux disques abrasifs s'y adaptant.The invention relates to the technical sector of portable machines to be ground and to the abrasive discs adapting thereto.

Selon l'art antérieur, représenté figure 1, la machine portative à meuler, à abraser, comprend, en bout de la partie motrice, une cloche (1) avec une ouverture axiale pour le passage d'un axe d'entraínement (non représenté). Cette cloche présente, sur sa périphérie, une rangée de poils (2) d'étanchéité venant en appui sur la partie de matériau à meuler. La cloche présente, sur sa face arrière (1a), un conduit (1b) permettant la fixation d'un flexible d'aspiration, non représenté, et des moyens en saillies (1c) pour l'ancrage de la machine électroportative. La cloche reçoit un premier sous-ensemble (A) incluant une galette en mousse (3) et un disque (4) dont la face apparente (4a) est réalisée avec des moyens auto-agrippant du type de ceux connus sous la marque VELCRO, ladite face apparente constituant la partie mâle de la fixation. La liaison du disque et de la galette s'effectue par une couche de colle (5) disposée régulièrement en faisant interface entre le disque et la galette.According to the prior art, shown in Figure 1, the portable machine to grind, to be abraded, includes, at the end of the driving part, a bell (1) with an axial opening for the passage of a drive axis (not represented). This bell has, on its periphery, a row of hairs (2) seal coming to rest on the part of material to be ground. The bell has, on its rear face (1a), a conduit (1b) allowing the fixing of a suction hose, not shown, and projecting means (1c) for the anchoring of the portable electric machine. The bell receives a first subset (A) including a foam wafer (3) and a disc (4), the visible face (4a) is made with self-gripping means of the type of those known under the brand VELCRO, said visible face constituting the male part of the fixing. The connection of the disc and the cake is made by a layer of adhesive (5) arranged regularly by interfacing between the disc and pancake.

Le second sous-ensemble (B) qui est rapporté et fixé sur le premier sous-ensemble est constitué par le disque abrasif (6) lui-même qui est fixé également par collage (7) selon une couche appropriée sur un disque (8) dont la face apparente (8a) est constituée par des moyens auto-agrippant du type VELCRO en constituant la partie femelle de la fixation. Ladite partie (8a) vient ainsi se solidariser par accrochage au premier sous-ensemble (A) à la partie mâle (4a) formée sur le disque (4). Les deux sous-ensembles (A-B) se trouvent ainsi à l'intérieur de la cloche précitée. On a représenté, figure 1, cet ensemble, selon l'art antérieur.The second sub-assembly (B) which is attached and fixed on the first sub-assembly is constituted by the abrasive disc (6) itself which is fixed also by gluing (7) in a suitable layer on a disc (8) the visible face (8a) of which is constituted by self-gripping means of VELCRO type by constituting the female part of the fixing. Said part (8a) is thus joined by attachment to the first sub-assembly (A) to the male part (4a) formed on the disc (4). The two subsets (A-B) are thus located inside the aforementioned bell. We have represented, Figure 1, this set, according to the prior art.

Le problème posé réside dans l'évacuation des particules abrasives et des matières qui apparaissent de par le fonctionnement de la machine. On constate, en effet, une certaine difficulté à leur évacuation, la couche de colle (7) faisant office de barrière d'étanchéité.The problem is the removal of abrasive particles and materials that appear from the operation of the machine. We notes, in fact, a certain difficulty in their evacuation, the layer of glue (7) acting as a sealing barrier.

On connaít, par le brevet EP n° 1.177.861, le concept de réaliser des perforations sur une bande abrasive en continu, ces perforations étant établies sur une partie de l'épaisseur de la bande sans effet d'évacuation des particules abrasives, les conditions d'intervention étant différentes de l'objet de l'invention.We know from EP patent No. 1,177,861 the concept of making perforations on a continuous abrasive belt, these perforations being established on a part of the thickness of the strip without effect of evacuation of abrasive particles, the intervention conditions being different from the subject of the invention.

Le but recherché, selon l'invention, était donc de remédier au problème posé précité en recherchant une solution simple à mettre en oeuvre.The aim sought, according to the invention, was therefore to remedy the problem posed above by seeking a simple solution to implement artwork.

Selon une première caractéristique, le disque abrasif pour machine électroportative à meuler comprend une partie discale abrasive présentant sur sa surface abrasive une multitude de micro-perforations, ladite partie abrasive étant solidarisée par une couche de colle à une partie sous-jacente réalisée en tissu non tissé, faisant office de moyen de filtration, et en ce que les autres micro-perforations traversent intégralement la couche de colle et débouchent dans l'épaisseur de la partie seconde en tissu non tissé, l'ensemble permettant la diffusion et évacuation des particules des matières meulées et abrasées par aspiration latérale. According to a first characteristic, the machine abrasive disc portable power tool includes an abrasive disc portion having on its abrasive surface a multitude of micro-perforations, said part abrasive being joined by a layer of glue to an underlying part made of non-woven fabric, acting as a filtration means, and in that the other micro-perforations pass completely through the adhesive layer and open into the thickness of the second part of non-woven fabric, the assembly allowing the diffusion and evacuation of the particles of the materials ground and abraded by lateral suction.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These and other characteristics will become apparent from the following the description.

Pour fixer l'objet de l'invention illustré d'une manière non limitative aux figures des dessins où :

  • la figure 1 est une vue, selon l'art antérieur, d'un ensemble d'une cloche adaptable sur machine électroportative à meuler ou à abraser incluant le disque abrasif.
  • la figure 2 est une vue des composants, selon l'invention, adaptables de la cloche précitée.
  • la figure 3 est une vue en coupe selon la figure 2, ligne A.A de celle-ci.
  • la figure 4 est une vue partielle à grande échelle illustrant la partie discale abrasive.
  • la figure 5 est une vue partielle en coupe illustrant l'évacuation des particules.
To fix the subject of the invention illustrated in a nonlimiting manner in the figures of the drawings where:
  • Figure 1 is a view, according to the prior art, of a set of a bell adaptable on an electric portable grinding or abrading machine including the abrasive disc.
  • Figure 2 is a view of the components, according to the invention, adaptable from the aforementioned bell.
  • Figure 3 is a sectional view along Figure 2, line AA thereof.
  • Figure 4 is a partial view on a large scale illustrating the abrasive disc portion.
  • Figure 5 is a partial sectional view illustrating the evacuation of the particles.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins.In order to make the object of the invention more concrete, it is described now in a nonlimiting manner illustrated in the figures of the drawings.

L'invention vise à réaliser, de manière nouvelle, le deuxième sous-ensemble qui inclut le disque abrasif.The invention aims to achieve, in a new way, the second subset which includes the abrasive disc.

Ce sous-ensemble (C) comprend une partie discale abrasive (10), constituée en corindon ou autres matériaux, présentant sur sa surface abrasive (10a) une multitude de micro-perforations (10b). Cette partie abrasive est solidarisée par une couche de colle (11) à une partie sous-jacente (12) réalisée en tissu non tissé présentant une certaine épaisseur, faisant office de moyen de filtration. Les micros perforations (10b) établies sur la partie abrasive, traversent intégralement la couche de colle (11) et débouchent dans l'épaisseur (e) de la partie seconde (12) en tissu non tissé.This sub-assembly (C) comprises an abrasive disc part (10), made of corundum or other materials, having on its surface abrasive (10a) a multitude of micro-perforations (10b). This part abrasive is secured by a layer of adhesive (11) to an underlying part (12) made of nonwoven fabric having a certain thickness, acting as a filtration medium. The micro perforations (10b) established on the abrasive part, pass entirely through the adhesive layer (11) and open into the thickness (e) of the second part (12) of nonwoven fabric.

En outre, et comme représenté figure 5, les micros perforations (10b), établies sous forme d'un poinçonnage de la surface abrasive, déforment celles-ci et constituent des puits d'air d'aspiration, les particules et poussières passant obligatoirement par les puits. Lorsque l'aspiration est arrêtée, les particules abrasées tombent naturellement par l'effet de la pesanteur. Ainsi, par cette structure, l'évacuation des particules et poussière, à travers le filtre constitué, se fait par aspiration latérale de par la conception de la cloche (1) associée à la machine électroportative.In addition, and as shown in Figure 5, the micro perforations (10b), established in the form of a punching of the abrasive surface, deform these and constitute suction air wells, the particles and dust must pass through the wells. When the suction is stopped, the abraded particles fall naturally by the effect of gravity. So, by this structure, the evacuation of particles and dust, through the filter formed, is done by lateral suction through the design of the bell (1) associated with the portable electric machine.

Cette disposition particulière permet ainsi une meilleure prise en charge des particules des matières meulées et abrasées qui traversent ainsi la couche de tissu non tissé (12), faisant office de filtre, pour être évacuées latéralement par aspiration. La couche de tissu non tissé (12) est ainsi fixée et accrochée avec la partie mâle (4a) auto-agrippante en forme de crochets du disque (4) associé à la galette (3) en mousse pour assurer le maintien de l'ensemble.This particular arrangement thus allows better handling charge of particles of ground and abraded material which thus pass through the layer of nonwoven fabric (12), acting as a filter, to be evacuated laterally by suction. The layer of non-woven fabric (12) is thus fixed. and hooked with the hook-shaped hook-shaped male part (4a) of the disc (4) associated with the foam pad (3) to ensure the maintenance of all.

Selon une disposition avantageuse, représentée figure 4, l'abrasif en corindon est maintenu par une imprégnation de latex colloïdal (10c) qui constitue un enduit très fin et dont la propriété et fonction, outre de maintenir les grains abrasifs, est de faire glisser plus facilement les particules abrasées. Cette imprégnation (10c) constitue ainsi un enduit anti-encrassant.According to an advantageous arrangement, represented in FIG. 4, the abrasive in corundum is maintained by an impregnation of colloidal latex (10c) which constitutes a very fine coating and whose property and function, in addition to maintain the abrasive grains, is to slide the abraded particles. This impregnation (10c) thus constitutes an anti-fouling coating.

Par la disposition nouvelle et originale de l'invention, outre la meilleure évacuation des particules des matières abrasées et meulées, on a constaté une plus grande longévité du disque abrasif (10) lui-même. La profondeur des ouvertures formées par les micros perforations (10b) dans la partie disque abrasive permet une aération complète du sous-ensemble (c) et donc évite un encrassage de la partie abrasive (10) elle-même, permettant ainsi une plus grande longévité.By the new and original provision of the invention, in addition to the better removal of particles from abraded and ground materials, found a greater longevity of the abrasive disc (10) itself. The depth of the openings formed by the micro perforations (10b) in the abrasive disc part allows complete ventilation of the sub-assembly (c) and therefore avoids fouling of the abrasive part (10) itself, allowing thus greater longevity.

Les avantages ressortent bien de l'invention. On souligne la simplicité de celle-ci et sa mise en oeuvre rapide et la meilleure qualité de l'aspiration des particules et une grande longévité améliorée du disque abrasif.The advantages emerge clearly from the invention. We underline the simplicity of it and its rapid implementation and the best quality of particle suction and improved long life of the disc abrasive.
