Abstract
Description
Dispositif pour le décapage par écaillage des peintures et revetements . Device for stripping by peeling of paints and coatings.
La présente invention concerne un dispositif pour le décapage par écaillage des peintures et des revétements , par exemple pour le ponçage ou le décapage des surfaces planes enduites de platre ou des surfaces recouvertes de peinture ( Sols , toles ) Certains disques équipés de façon semblable avec des pastilles composées d'un S agglomérat contenant des granules de diamant permettent le travail de surfaçage ou de décapage , mais en faisant plus de poussière ; le support des pastilles composées , composé d'un plateau sur lequel celles-ci sont rapportées , est ensuite mis au rebut . The present invention relates to a device for peeling off paint and coatings, for example for sanding or stripping flat surfaces coated with plaster or surfaces covered with paint (Soils, sheets) Some discs similarly equipped with pellets composed of an agglomerate containing diamond granules allow the work of surfacing or stripping, but making more dust; the support of compound pellets, consisting of a plate on which these are reported, is then discarded.
Le dispositif selon l'invention permet de remédier à cet inconvénient . L'invention concerne un dispositif pour le décapage par écaillage des peintures et des revetements 4O caractérisé en ce qu'il comprend un plateau (1) comportant des rainures ( 8 ) de section tronconique (13 ) en périphérie , dans lesquelles sont placées des pastilles en carbure ( 5 ) venant en contact sur une butée (2) , fixée sur le plateau (1) . Il comporte en effet selon une première caractéristique , des pastilles carbure remplaçant les pastilles diamantées ; les pastilles de forme triangulaire , placées dans les rainures et abloquées , 45 permettent la pénétration dans le matériau du fait de la faible surface aux points de contacts ; la réalisation de l'ablocage étant en queue d'aronde : les pastilles disposées en sens anti-horaire sur le plateau venant au contact de la butée poussées en translation par le flasque fixé sur le plateau . Selon un mode particulier de réalisation , l'ablocage des pastilles disposées sur le 20 plateau peut etre réalisé par un couvercle fixé sur celui-ci et dans lequel des trous tronconiques auront été réalisés et dans lesquels le passage des pastilles est prévu . The device according to the invention overcomes this disadvantage. The invention relates to a device for stripping by peeling paints and coatings 4O characterized in that it comprises a plate (1) having grooves (8) of frustoconical section (13) at the periphery, in which are placed pellets carbide (5) contacting a stop (2), fixed on the plate (1). It comprises in fact according to a first characteristic, carbide pellets replacing the diamond pellets; the triangular shaped pellets, placed in the grooves and unlocked, 45 allow penetration into the material due to the small surface at the points of contact; the embodiment of the locking being dovetail: the pellets arranged in a counterclockwise direction on the plate coming into contact with the stop pushed in translation by the flange fixed on the plate. According to a particular embodiment, the clamping of the pellets disposed on the plate can be achieved by a cover fixed thereto and in which frustoconical holes have been made and in which the passage of the pellets is provided.

En référence à ces dessins , le plateau (1) est de forme cylindrique et plate sur la périphérie ; la partie centrale déportée comporte un alésage pour le montage sur la meuleuse . Selon deux variantes , le plateau (1) pouvant etre usiné avec une partie tronconique circulaire divisée en parties égales par le fraisage de rainures ( 8 ) pour la réception des pastilles ( 5 ) de forme triangulaire équilatérale ( 60°) d'épaisseurs identiques aux largeurs des rainures (8) ; les deux angles formés par la partie tronconique (13 ) mesurant aussi 60° ; de ce que les triangles formés par les lignes d'épure des parties tronconiques (13 ) soient de taille inférieure aux triangles formés par les lignes d'épure de ceux formés par les pastilles ( 5 ) , réalisant le principe de serrage en queue d'aronde obtenu avec la butée (2) soudée à la périphérie du plateau (1) après l'y avoir emboitée , et le flasque ( 3 ) venant faire buter les pastilles ( 5 ) sur la butée( 2 ) , par l'action de serrage obtenue avec les vis (4 ) passant par les trous (12 ) du flasque 30 35 4n (3 ) . On entend pour l'obtention du serrage des pastilles (5 ) dans les rainures ( 8 ) que la taille des épures des triangles des pastilles (5 ) est supérieure à la taille des épures des triangles formés par les parties tronconiques (13) . With reference to these drawings, the plate (1) is cylindrical in shape and flat on the periphery; the remote central part has a bore for mounting on the grinder. According to two variants, the plate (1) can be machined with a circular frustoconical portion divided into equal parts by the milling grooves (8) for receiving the pellets (5) of equilateral triangular shape (60 °) of identical thicknesses to groove widths (8); the two angles formed by the frustoconical portion (13) also measuring 60 °; that the triangles formed by the lines of the frustoconical portions (13) are of smaller size than the triangles formed by the lines of purity of those formed by the pellets (5), realizing the principle of clamping the tail of aronde obtained with the abutment (2) welded to the periphery of the plate (1) after being engaged, and the flange (3) abutting the pellets (5) on the abutment (2), by the action of tightening obtained with the screws (4) passing through the holes (12) of the flange 30 4n (3). In order to obtain the tightening of the pellets (5) in the grooves (8), it is meant that the size of the trims of the triangles of the pellets (5) is greater than the size of the truncations of the triangles formed by the frustoconical parts (13).
Le dispositif principalement pour le plateau (1) peut recevoir un traitement thermique en raison du matage pouvant s'exercer sur les sommets des parties tronconiques ( 13). The device mainly for the tray (1) can receive a heat treatment due to the matting that can be exerted on the tops of the frustoconical portions (13).
Fonctionnement : La pièce (2 ) étant soudée sur le pourtour du plateau (1) à sa périphérie extérieure est donc fixe ; la descente du flasque ( 3 ) axe Oy ; sens yO assurée par le serrage des vis Ad (4) dans les trous taraudés (9) assure une immobilisation dans l'axe Ox ou xO après translation dans le sens xO dans la rainure ( 8 ) sur le plateau (1) des pastilles (5 ) venant en contact sur la surface tronconique (7) , puis enserrées par le contact puis la pression exercées par la surface tronconique (6) du flasque (3 ) L' immobilisation des pastilles ( 5 ) dans le sens Oz ou Zo dans les rainures ( 8 ) du fait que celles -ci sont de 45 memes épaisseurs et de memes largeurs . Selon une variante , le plateau (1) usiné avec des encoches inclinées (11 ), per-mettant le placement des pastilles carbure (5 ) standard et leur assise ; l'ablocage des pastilles ( 5 ) étant réalisé avec un couvercle (2 A) dont les trous tronconiques (10 )sont disposés de façon correspondante aux encoches (11) du plateau (1) ; des trous ( 12) correspondants à des trous taraudés (9) sur le plateau (1) , permettant le passage des vis (4) , permettant ensuite 1' application dans les encoches (11) des pastilles (5 ) puis leur enserrage par le vissage simultané des vis (4) . Operation: The part (2) being welded on the periphery of the plate (1) at its outer periphery is therefore fixed; the descent of the flange (3) axis Oy; direction yO ensured by the tightening of the screws Ad (4) in the threaded holes (9) ensures immobilization in the axis Ox or xO after translation in the xO direction in the groove (8) on the plate (1) of the pellets ( 5) coming into contact on the frustoconical surface (7), then gripped by the contact then the pressure exerted by the frustoconical surface (6) of the flange (3). The immobilization of the pellets (5) in the direction Oz or Zo in the grooves (8) because these are of 45 same thicknesses and widths. According to a variant, the plate (1) machined with inclined notches (11), permitting the placement of standard carbide pellets (5) and their seating; the padlock (5) being formed with a cover (2A) whose frustoconical holes (10) are arranged correspondingly to the notches (11) of the plate (1); holes (12) corresponding to tapped holes (9) on the plate (1), allowing the screws (4) to pass therethrough, then allowing the pellets (5) to be applied into the notches (11) and then clamped by the simultaneous screwing of the screws (4).
Fonctionnement : La descente du couvercle (2 A) assure une immobilisation des pastilles ( 5 ) assises 25 dans les rainures (11) dans les axes Ox et Oy grace aux pentes formées par les parties tronconiques ( 7 ) et ( 6) . 1' immobilisation dans l'axe zO ou Oz étant réalisée du fait que les trous tronconiques (10 ) et les pastilles ( 5 ) sont de meme largeurs et de memes épaisseurs . Le dispositif selon l'invention est particulièrement destiné au décapage des 30 peintures ou autres revetements ( Béton , acier) sur des surfaces dures et planes . Operation: The lowering of the lid (2 A) ensures immobilization of the pellets (5) seated in the grooves (11) in the Ox and Oy axes by means of the slopes formed by the frustoconical portions (7) and (6). 1 'immobilization in the axis zO or Oz being carried out because the frustoconical holes (10) and the pellets (5) are the same widths and thicknesses. The device according to the invention is particularly intended for stripping paints or other coatings (concrete, steel) on hard and flat surfaces.
