Description

L'invention se rapporte aux outils de pose ou de retrait d'un joint sans fin en élastomère dans un dispositif de projection d'eau.The invention relates to tools for installing or removing an endless elastomer seal in a water spray device.

On connaît par le brevet français 2 902 035 un outil de mise en place d'un joint dans une gorge d'un dispositif de projection de jet d'eau. Cet outil comprend un patin d'un seul tenant, rigide, de symétrie par rapport à un plan longitudinal médian et ayant une face principale sur laquelle est usinée au moins une rampe du côté d'une extrémité.We know by the French patent 2,902,035 a tool for placing a seal in a groove of a water jet projection device. This tool comprises a shoe in one piece, rigid, of symmetry with respect to a median longitudinal plane and having a main face on which is machined at least one ramp on the side of one end.

Ce patin a souvent une longueur de plusieurs mètres pour s'étendre sur toute la largeur d'un voile de non-tissé à consolider passant devant le dispositif de projection d'eau ou injecteur. Il est fragile. En raison de sa longueur, il est difficile à transporter et à emmagasiner.This pad often has a length of several meters to extend over the entire width of a web of nonwoven to be consolidated passing in front of the water projection device or injector. He is fragile. Due to its length, it is difficult to transport and store.

L'invention pallie ces inconvénients par un outil ayant un embout d'un seul tenant, rigide, de symétrie par rapport à un plan longitudinal médian et ayant une face principale sur laquelle est usinée au moins une rampe du côté d'une extrémité, caractérisé en ce que, du côté de l'autre extrémité, est usiné, sur la face principale, un plateau d'extrémité en dénivelé, à un premier niveau par rapport à une butée à un deuxième niveau plus bas que le premier niveau. Une lame, d'un seul tenant, plus longue et plus mince que l'embout est, par l'une de ses extrémités, en butée sur la butée et est serrée entre le plateau d'extrémité et une pièce de maintien, dont la face supérieure plane est au même niveau que le niveau le plus haut de la face principale. Le premier et le deuxième niveaux sont plus bas que le niveau le plus haut de la face principale. On peut donner ainsi à l'embout une longueur bien plus petite. L'embout peut avoir par exemple une longueur comprise entre 70 et 300 cm. La lame peut avoir une longueur comprise entre 1 000 et 8 000 cm. Comme la lame est serrée, seulement à une partie assez courte à l'une de ses extrémités, entre le plateau d'extrémité et la pièce de maintien, la lame, tout en étant plus mince et en pouvant même être enroulable, reste suffisamment apte à pousser l'embout dans la chambre d'un injecteur où un joint sans fin en matière élastomère doit être mis en place dans une gorge. De préférence, la lame est un feuillard d'acier inoxydable. L'embout est en une matière plastique telle qu'en ABS, qui glisse facilement, notamment sur de l'acier inoxydable.The invention overcomes these drawbacks by means of a tool having a one-piece, rigid tip of symmetry with respect to a median longitudinal plane and having a main face on which at least one ramp is machined on the side of one end, characterized in that, on the side of the other end, is machined, on the main face, an end plate in unevenness, at a first level relative to an abutment at a second level lower than the first level. A blade, in one piece, longer and thinner than the tip is, by one of its ends, in abutment on the abutment and is clamped between the end plate and a retaining piece, the flat upper face is at the same level as the highest level of the main face. The first and second levels are lower than the highest level of the main face. It is thus possible to give the tip a much shorter length. The end piece may for example have a length of between 70 and 300 cm. The blade can have a length between 1000 and 8000 cm. As the blade is clamped, only at a rather short part at one of its ends, between the end plate and the holder, the blade, while being thinner and even being able to be rolled up, remains sufficiently fit to push the nozzle into the chamber of an injector where an endless seal made of elastomeric material must be placed in a groove. Preferably, the blade is a stainless steel metal sheet. The tip is made of a plastic material such as ABS, which slides easily, in particular on stainless steel.

Suivant un mode de réalisation particulièrement préféré, la lame comporte, à l'extrémité près de l'embout, une face d'extrémité transversale incurvée de manière convexe, conjuguée d'une face transversale incurvée de manière concave de l'embout, de manière à bien abouter l'embout et la lame, mais à pouvoir les séparer ensuite et les emmagasiner et les transporter indépendamment.According to a particularly preferred embodiment, the blade comprises, at the end near the tip, a convexly curved transverse end face, combined with a concavely curved transverse face of the tip, so to properly butt the tip and the blade, but to be able to separate them afterwards and store and transport them independently.

Suivant un mode de réalisation, l'outil est un outil de pose du joint et comporte une face supérieure principale plane et lisse de glissement et la face inférieure principale opposée, sur laquelle sont ménagés successivement, suivant le sens longitudinal de glissement de l'outil, un toc d'entraînement et une rampe s'éloignant de la face supérieure au fur et à mesure qu'elle s'éloigne du toc. Le toc ne se trouve, de préférence, que dans la partie médiane suivant la largeur de la face inférieure. De préférence, la rampe ne se trouve que dans les parties latérales suivant la largeur de la face inférieure. Le toc définit une rainure de réception d'un joint.According to one embodiment, the tool is a tool for installing the seal and comprises a flat and smooth main upper sliding face and the opposite main lower face, on which are formed successively, in the longitudinal sliding direction of the tool , a practice dog, and a ramp moving away from the top face as it moves away from the dog. The dog is preferably only in the middle part along the width of the lower face. Preferably, the ramp is only in the side parts along the width of the lower face. The dog defines a groove for receiving a seal.

Suivant un autre mode de réalisation, l'outil est un outil de retrait d'un joint. Deux patins longitudinaux ayant chacun une extrémité avant sont issus de la face inférieure plane de l'embout, sur la face supérieure de l'embout, et sont usinés successivement de l'avant vers l'arrière :

  • à l'avant, deux facettes sont inclinées par rapport à la face inférieure en allant jusqu'aux extrémités des patins en y formant des becs de raclage ;
  • une rampe en T, du bord transversal inférieur duquel sont issues les deux facettes et dont le bord transversal supérieur le plus haut, moins large que le bord transversal inférieur, est commune au bord transversal avant d'une barre centrale longitudinale ; et
  • la barre centrale est de moindre largeur que la largeur de la face inférieure.
According to another embodiment, the tool is a seal removal tool. Two longitudinal sliders each having a front end come from the flat underside of the end piece, on the upper face of the end piece, and are machined successively from the front to the rear:
  • at the front, two facets are inclined with respect to the lower face, going as far as the ends of the runners, forming scraping lugs there;
  • a T-shaped ramp, from the lower transverse edge from which the two facets originate and whose uppermost transverse edge, narrower than the lower transverse edge, is common to the front transverse edge of a central longitudinal bar; and
  • the central bar is less wide than the width of the lower face.

Dans ce mode de réalisation, l'embout peut comprendre de part et d'autre de la barre centrale deux barrettes longitudinales, dans l'alignement longitudinal des facettes, de moindre épaisseur que la barre centrale, issues du bord transversal supérieur le moins haut de la rampe et se prolongeant vers l'arrière au-delà de la barre centrale jusqu'à des bords arrières en arc-de-cercle, en définissant entre elles et avec le bord arrière de la barre centrale et la face supérieure un logement de réception de la pièce de maintien de la lame distinct, à bord circulaire, s'adaptant aux bords arrière en arc-de-cercle, la lame ayant l'épaisseur des barrettes et la somme de l'épaisseur de la lame et de l'épaisseur de la pièce de maintien étant égale à l'épaisseur de la barre centrale.In this embodiment, the end piece may comprise on either side of the central bar two longitudinal bars, in the longitudinal alignment of the facets, of less thickness than the central bar, coming from the lower upper transverse edge of the ramp and extending aft beyond the center bar to rear arcuate edges, defining between they and with the rear edge of the central bar and the upper face a housing for receiving the separate blade holding part, with a circular edge, adapting to the rear edges in an arc of a circle, the blade having the thickness of the bars and the sum of the thickness of the blade and the thickness of the retaining piece being equal to the thickness of the central bar.

De préférence, l'angle des facettes avec la face inférieure de l'embout est compris entre 5 et 30°. De préférence, l'angle de la rampe avec la face inférieure de l'embout est compris entre 5 et 30°.De préférence, l'angle de la rampe avec la face inférieure de l'embout est égal à celui des facettes.Preferably, the angle of the facets with the lower face of the end piece is between 5 and 30°. Preferably, the angle of the ramp with the underside of the endpiece is between 5 and 30°. Preferably, the angle of the ramp with the underside of the endpiece is equal to that of the facets.

De préférence, dans les deux modes de réalisation mentionnés ci-dessus, il est prévu un trou de centrage dans l'embout et un doigt de la pièce de maintien pénétrant dans ce trou en passant par une ouverture de la lame superposée au trou.Preferably, in the two embodiments mentioned above, there is provided a centering hole in the endpiece and a finger of the retaining part penetrating into this hole by passing through an opening of the blade superimposed on the hole.

  • the figure 2 is an exploded view of a seal removal tool according to the invention; and
  • the picture 3 is a bottom view of the tool from the figure 2 .

L'outil représenté à la figure 1 comprend un embout, en un matériau qui glisse facilement sur de l'acier inoxydable comme de l'ABS, est constitué d'un patin ayant une face 40 supérieure, rectangulaire, plane et lisse. La face latérale gauche, de l'outillage est en forme de T ayant une hampe 41 et une barrette 42. La barrette 42 est rectangulaire, en ayant une largeur de 20 mm et une hauteur de 10 mm. La hampe 41 est sensiblement rectangulaire avec une largeur de 10 mm et une hauteur de 5 mm. La face inférieure (supérieure à la figure) de la hampe 41 est plane et parallèle à la face 40. La hampe 41 constitue un plot ou toc d'entraînement, en étant interrompue par une rainure 43 ouverte vers le bas (vers le haut à la figure). Un joint peut être mis dans cette rainure 43 et enfilé ainsi autour du toc 41. De l'autre côté de la rainure 43, la face inférieure se poursuit par une barre 44 centrale longitudinale sur laquelle est apposée une flèche F indiquant le sens d'introduction du coulisseau. Deux rampes 45, symétriques l'une de l'autre par rapport à la barre 44, sont disposées sur les bords longitudinaux de l'outillage. Les rampes sont inclinées suivant une pente de 15° de la surface inférieure 42 de la barre à une plateforme 46 la plus basse de l'outillage qui est au même niveau que la face inférieure de la hampe 41 et que la barre 44. L'embout a deux épaulements 51.The tool shown in figure 1 comprises a tip, made of a material which slides easily on stainless steel such as ABS, consists of a pad having an upper face 40, rectangular, flat and smooth. The left side face of the tool is T-shaped having a stem 41 and a bar 42. The bar 42 is rectangular, having a width of 20 mm and a height of 10 mm. The shaft 41 is substantially rectangular with a width of 10 mm and a height of 5 mm. The lower face (upper in the figure) of the shaft 41 is flat and parallel to the face 40. The shaft 41 constitutes a stud or drive dog, being interrupted by a groove 43 open downwards (upwards at the figure). A seal can be placed in this groove 43 and thus threaded around the dog 41. On the other side of the groove 43, the lower face continues with a central longitudinal bar 44 on which is affixed an arrow F indicating the direction of introduction of the slider. Two ramps 45, symmetrical to each other with respect to the bar 44, are arranged on the longitudinal edges of the tool. The ramps are inclined at a slope of 15° from the lower surface 42 of the bar to a lowest platform 46 of the tool which is at the same level as the underside of the shaft 41 and the bar 44. end piece with two shoulders 51.

L'outil comprend aussi une lame 47 constituée d'un feuillard ou lame d'acier inoxydable enroulable, fixée de manière amovible à l'embout à l'aide d'une pièce 48 de maintien ayant un doigt 49, qui pénètre dans un trou 50 d'un plateau 52 d'extrémité de l'embout. La pièce 48 de maintien est vissée à l'embout par deux vis 51 et écrous 55, de manière à ce que la face supérieure de la pièce 48 de maintien soit plane et à affleurement avec la face supérieure du toc 41. Le niveau du plateau 52 est plus bas que celui de deux butées 53 constituées par les faces d'extrémité arquées de deux barrettes 54 longitudinales. La face supérieure des barrettes 54 est plus basse que la face supérieure du toc 41 et plus haute que la face supérieure du plateau 42.The tool also comprises a blade 47 consisting of a roll-up stainless steel strip or blade, removably fixed to the tip by means of a holding part 48 having a finger 49, which penetrates into a hole 50 of a plate 52 end of the tip. The holding part 48 is screwed to the end piece by two screws 51 and nuts 55, so that the upper face of the holding part 48 is flat and flush with the upper face of the dog 41. The level of the plate 52 is lower than that of two stops 53 formed by the arcuate end faces of two longitudinal strips 54. The upper face of the bars 54 is lower than the upper face of the dog 41 and higher than the upper face of the plate 42.

Le mode de réalisation représenté aux figures 2 et 3 est un outil de retrait d'un joint. Il comprend un embout d'un seul tenant de symétrie par rapport à un plan médian longitudinal, ayant une face 20 inférieure plane, de laquelle sont issus deux patins 21 longitudinaux ayant chacun une extrémité avant, et une face supérieure. La face 20 est inférieure à la figure, mais lorsque l'outillage est destiné à être utilisé dans un injecteur incliné ou orienté différemment, elle peut se trouver au-dessus de l'autre face. Dans le présent mémoire, on désigne les deux faces par inférieure et supérieure simplement pour faciliter l'exposé.The embodiment shown in figure 2 and 3 is a gasket removal tool. It comprises an end piece in a single piece of symmetry with respect to a longitudinal median plane, having a flat lower face 20, from which two longitudinal pads 21 come, each having a front end, and an upper face. Face 20 is lower than the figure, but when the tooling is intended to be used in an inclined or differently oriented injector, it may be above the other face. In this specification, the two faces are referred to as lower and upper simply for ease of discussion.

Sur la face supérieure opposée à la face 20, sont usinées successivement de l'avant vers l'arrière, à l'avant, deux facettes 22 inclinées d'un angle de 15°, par rapport à la face 20 inférieure, en allant jusqu'aux extrémités des patins 21 en y formant ainsi des becs de raclage.On the upper face opposite the face 20, are machined successively from front to rear, at the front, two facets 22 inclined at an angle of 15°, relative to the lower face 20, going up to 'at the ends of the pads 21 thereby forming therein scraping spouts.

Une rampe 23 en T, qui est inclinée de 15° par rapport à la face inférieure et du bord transversal inférieur duquel sont issues les deux facettes 22 et dont le bord transversal le plus haut, moins large que le bord transversal inférieur, est commun au bord avant d'une barre 24 centrale de moindre largeur que la largeur de la face 20 inférieure. De part et d'autre de la barre 24 centrale, s'étendent deux barrettes 25 longitudinales, de moindre épaisseur que la barre 24 centrale, dans l'alignement longitudinal des facettes 22 et se prolongeant vers l'arrière au-delà de la barre 24 centrale, en définissant entre elles et avec le bord arrière de la barre 24 centrale et la face supérieure un logement de réception d'une pièce 26 de maintien d'une lame 27 à bord circulaire, s'adaptant au bord arrière en arc-de-cercle. La lame 27 a l'épaisseur des barrettes 25 et la somme de l'épaisseur de la lame 27 et de l'épaisseur de la pièce 26 de maintien est égale à l'épaisseur de la barre 24 centrale. La lame a une longueur de 1 000 à 8 000 mm, alors que l'embout a une longueur de 70 à 300 mm.A T-shaped ramp 23, which is inclined by 15° with respect to the lower face and the lower transverse edge from which the two facets 22 originate and whose highest transverse edge, narrower than the lower transverse edge, is common to the front edge of a central bar 24 of lesser width than the width of the lower face 20.
