Selon le procédé de L'invention, illustré sur
Les figures 1 à 3, on place deux embouts 2 sur un axe 8. According to the method of the invention, illustrated on
Figures 1 to 3, two end pieces 2 are placed on an axis 8.
Comme on peut le voir sur Les figures 1 à 3 et également sur Les figures 4 et 5, chaque embout se compose d'une partie tubulaire 2a et d'une partie évasée 2b formée d'une seule pièce avec la partie tubulaire 2a. Cette dernière comporte un alésage central traversé par L'axe 8. Son diamètre extérieur est fileté sur au moins une partie de sa longueur. La partie évasée 2b présente une face interne 2c, qui sera dirigée vers L'intérieur de
L'enceinte lorsque celle-ci sera terminée, et dont le diamètre va croissant à partir du diamètre interne de l'alésage de la partie tubulaire jusqu a une valeur maximale correspondant au diamètre extérieur de L'embout 2.La paroi externe de la partie évasée 2b se compose d'un épaulement 2d sensiblement perpendiculaire à L'axe de La partie tubulaire et dans lequel est pratiquée une gorge annulaire 2e en retrait par rapport à l'épaulement 2d. Enfin, la partie évasée 2b comporte une partie tronconique 2f qui effectue le raccordement entre L'épaulement 2d et La paroi ou face interne 2c.As can be seen in Figures 1 to 3 and also in Figures 4 and 5, each nozzle consists of a tubular part 2a and a flared part 2b formed in one piece with the tubular part 2a. The latter has a central bore through which the axis 8 passes. Its external diameter is threaded over at least part of its length. The flared part 2b has an internal face 2c, which will be directed towards the interior of
The enclosure when this is completed, and the diameter of which increases from the internal diameter of the bore of the tubular part up to a maximum value corresponding to the external diameter of the end piece 2.The external wall of the part flared 2b consists of a shoulder 2d substantially perpendicular to the axis of the tubular part and in which is formed an annular groove 2e recessed with respect to the shoulder 2d. Finally, the flared part 2b comprises a frustoconical part 2f which makes the connection between the shoulder 2d and the wall or internal face 2c.
Comme on peut le voir particulièrement sur Les figures 4 et 5, la paroi tronconique 2f et la paroi interne 2c déterminent, vues en coupe, un profil en forme de coin d'angle relativement faible, de L'ordre de 10 à 20", que l'on appellera bec- dans la suite du texte Chacun des embouts 2 est réalisé en métal, par exemple en acier, mais peut Autre en tout matériau suffisamment résistant.As can be seen particularly in FIGS. 4 and 5, the frustoconical wall 2f and the internal wall 2c determine, seen in section, a profile in the form of a relatively small corner corner, of the order of 10 to 20 ", which will be called beak- in the rest of the text Each of the end pieces 2 is made of metal, for example steel, but may Other of any sufficiently resistant material.
Deux positionneurs 10 montés sur L'axe 8 et vissés sur Les filetages extérieurs des parties 2a de chacun des deux embouts sont fixés sur L'axe et.bloques en rotation par des vis 12. Two positioners 10 mounted on the axis 8 and screwed onto the external threads of the parts 2a of each of the two end pieces are fixed to the axis and rotated by means of screws 12.
Un tube de matière plastique 14 de faible épaisseur (environ 2 mm) est intercale entre Les parois internes 2c de chacun des embouts 2 et enserré entre ceux-ci. Comme on peut le voir plus nettement sur les figures 4 et 5, Le diamètre extérieur du tube 14 est inférieur de quelques miltimètres au diamètre extérieur des embouts. De cette manière, Les becs de chacun de ces embouts déterminent avec La surface extérieure du cylindre 14 un angLe rentrant. Le cylindre 14 sert de mandrin pour le bobinage des fibres de KevLar Sur la figure 1, on a représenté Les embouts et Le mandrin 14 avantbla mise en place de La couche bobinée. Sur la figure 2, une enveloppe de matériau composite 16 a été réalisée sur Les embouts et sur Le mandrin 14. Ce bobinage est réalisé au moyen d'un touret.De préférence, pour le corps de L'enceinte, on effectue deux passes à grand pas aLler-retour et une passe aLLer et retour à petit pas sur Le mandrin 14 et sur La partie tronconique 2f des embouts. Aux extrémités de L'enceinte, c'est-à-dire sur L'épaulement 2d et au niveau de La gorge annulaire 2e, Le bobinage est effectué uniquement avec un petit pas. A thin plastic tube 14 (approximately 2 mm) is interposed between the internal walls 2c of each of the end pieces 2 and sandwiched between them. As can be seen more clearly in Figures 4 and 5, the outer diameter of the tube 14 is a few millimeters smaller than the outer diameter of the tips. In this way, the spouts of each of these end pieces determine with the outer surface of the cylinder 14 a re-entrant angle. The cylinder 14 serves as a mandrel for winding the KevLar fibers. In FIG. 1, the end caps and The mandrel 14 are shown before the wound layer is put in place. In FIG. 2, an envelope of composite material 16 has been produced on the end caps and on the mandrel 14. This winding is produced by means of a drum. Preferably, for the body of the enclosure, two passes are made. big step back and forth and a go and back pass with small step on the mandrel 14 and on the frustoconical part 2f of the end pieces. At the ends of the enclosure, that is to say on the shoulder 2d and at the level of the annular groove 2e, the winding is carried out only with a small step.
L'imprégnation des fibres de résine poLymérisable est effectuée en même temps que leur bobinage, sur le même touret. CeLa permet d'obtenir une matière homogène dépourvue de bulles. On remarque que la couche bobinée dans L'angle rentrant forme par le bec de chacun des deux embouts 2 et la surface extérieure du mandrin 14 constitue un ancrage de cette couche. Aux deux extrémités, La couche bobinée pénètre dans La gorge annuLaire 2e de chacun des embouts. La fonction de cette gorge sera expliquée ultérieurement en référence à la figure 3. The polymerizable resin fibers are impregnated at the same time as their winding, on the same reel. This makes it possible to obtain a homogeneous material devoid of bubbles. Note that the layer wound in the re-entrant angle forms by the spout of each of the two end pieces 2 and the outer surface of the mandrel 14 constitutes an anchoring of this layer. At both ends, the coiled layer enters the 2nd annular groove of each of the end pieces. The function of this groove will be explained later with reference to FIG. 3.
L'épaisseur du bobinage est réalisée de ma niera à venir recouvrir en couches alternées imprégnées de résine l'ensemble de la surface sur une épaisseur calculee pour résister, après polymérisation, à la pression d'essai désirée. Lorsque cette épaisseur est atteinte, on met en place Les pièces d'ancrage (voir figure 3). Ces pièces d'ancrage sont constituées par une rondelle 20 de verrouillage et un écrou 18 de blocage de La rondelle. La rondelle 20 comporte une gorge annulaire de forme identique et de même diamètre que la gorge annulaire 2e de L'embout. Cette rondelle est montee sur la partie tubulaire 2a puis L'écrou de serrage 18 est vissé sur le filetage extérieur de cette partie tubulaire. Sur la partie gauche de la figure 3, on a représenté la rondelle et L'écrou avant serrage.Sur la partie droite de cette figure, ils ont été représentés après serrage. Cette opération est effectuée avant
L'étape de polymérisation, alors que le corps composite est encore malléable. Lorsqu'on serre Les écrous de compression 18 de la rondelle de verrouillage 20, le corps composite pénètre dans la gorge de la rondelle, dont il prend La forme. De cette manière, Les inserts ou embouts 2 sont mécaniquement verrouillés dans la masse composite dont ils font intimement et définitivement partie.The thickness of the winding is produced in such a way as to cover the entire surface in alternating layers impregnated with resin over a thickness calculated to resist, after polymerization, the desired test pressure. When this thickness is reached, the anchoring parts are put in place (see Figure 3). These anchoring parts are constituted by a locking washer 20 and a nut 18 for locking the washer. The washer 20 has an annular groove of identical shape and of the same diameter as the annular groove 2e of the end piece. This washer is mounted on the tubular part 2a then the clamping nut 18 is screwed onto the external thread of this tubular part. On the left side of Figure 3, the washer and the nut before tightening are shown. On the right side of this figure, they have been shown after tightening. This is done before
The polymerization stage, while the composite body is still malleable. When the compression nuts 18 of the locking washer 20 are tightened, the composite body penetrates into the groove of the washer, of which it takes the form. In this way, the inserts or end pieces 2 are mechanically locked in the composite mass of which they are intimately and definitively a part.
La structure composite est ensuite polymérisée. Pour cela, L'enceinte est placée dans une étuve mise à une température convenable. Pendant toute la durée de la polymérisation, L'enceinte est entratnée en rotation au moyen de L'axe 8. The composite structure is then polymerized. For this, the enclosure is placed in an oven brought to a suitable temperature. Throughout the duration of the polymerization, the enclosure is rotated by means of the axis 8.
Après L'étape de polymérisation, L'axe 8 et
Les positionneurs 10 sont retirés et peuvent etre utilisés pour la confection d'une autre enceinte. On obtient une pièce sèche, dont la surface intérieure est parfaitement Lisse.After the polymerization step, axis 8 and
The positioners 10 are removed and can be used for making another enclosure. A dry part is obtained, the interior surface of which is perfectly smooth.
La vessie 6 est introduite par L'une des ex trémités de L'enceinte. Une étanchéité est réalisée à chacune de ses extrémités entre la vessie et L'enceinte qui est ainsi prête à être raccordée au réseau d'utilisation par Les embouts 2. Si on désire réaliser une enceinte pourvue d'une seule ouverture, un des embouts 2 peut être obturé par tout moyen connu. De pLus, on peut réaLiser Les canalisations du réseau d'utilisation en tout matériau : comme des métaux, des matériaux com- posites, éventueLLement fabriqués par bobinage de La meme manière que L'enceinte. The bladder 6 is introduced through one of the ends of the enclosure. A seal is produced at each of its ends between the bladder and the enclosure which is thus ready to be connected to the use network by the end pieces 2. If it is desired to make an enclosure provided with a single opening, one of the end pieces 2 can be closed by any known means. In addition, it is possible to carry out the pipes of the use network in any material: such as metals, composite materials, possibly made by winding in the same way as the enclosure.
On a représenté sur Les figures 4 et 5 deux modes de réaLisation différents d'une étanchéité mecanique entre une vessie 6 et le corps de L'enceinte. There are shown in Figures 4 and 5 two different embodiments of a mechanical seal between a bladder 6 and the body of the enclosure.
On a représenté sur La figure 4 un premier mode de réaLisation d'une Liaison étanche entre La vessie 6 et une enceinte étanche réalisée conformément à
L'invention. Sur la figure 4, la vessie comporte une collerette 6a. Cette colLerette est logée dans une gorge circulaire formée à L'extrémité de La partie tubu
Laire de L'embout 2 et dans une gorge annuLaire formée en regard dans une canalisation de raccordement au réseau d'utilisation 22. Un écrou épauLé 24 bLoque Les canalisations 22 sur L'extrémité de La partie tubulaire 2a.FIG. 4 shows a first embodiment of a sealed connection between the bladder 6 and a sealed enclosure produced in accordance with
The invention. In Figure 4, the bladder has a flange 6a. This collar is housed in a circular groove formed at the end of the tubular part
Laire of the end piece 2 and in an annular groove formed opposite in a pipe connecting to the use network 22. A spangled nut 24 blocks the pipes 22 on the end of the tubular part 2a.
On a représente sur La figure 5 un deuxième mode de réalisation d'une Liaison étanche de La vessie 6 à L'enceinte. La partie annulaire 2a comporte un alésage 29 fileté intérieurement. Au fond de cet alésage, on trouve une gorge circulaire 2h dans laquelle est
Logé un bourrelet 6b forme à chacune des extrémités de
La vessie 6. Le bourrelet 6b est comprimé par une rondelle de forme 26 comportant une gorge annuLaire com plèmentaire de La gorge 2h. Cette rondelle 26 est calée en rotation. Elle est maintenue serrée par un écrou 29.There is shown in Figure 5 a second embodiment of a sealed connection of the bladder 6 to the enclosure. The annular part 2a has an internally threaded bore 29. At the bottom of this bore, there is a 2h circular groove in which is
Fitted with a bead 6b formed at each end of
The bladder 6. The bead 6b is compressed by a shaped washer 26 comprising an annular groove complementary to the throat 2h. This washer 26 is locked in rotation. It is held tight by a nut 29.
Une canalisation de raccordement à un réseau d'utilisa- tion 22 est introduite dans L'aLésage 2g. Un joint d'étanchéité torique 28 assure une étanchéité entre cette canalisation et L'extrémité de la partie tubulaire 2g.A pipe connecting to a use network 22 is introduced in the bore 2g. An O-ring seal 28 provides a seal between this pipe and the end of the tubular part 2g.
La vessie est placee par une des extrémités puis légèrement gonflée de manière à prendre sa pLace en faisant évacuer l'air piégé entre la vessie et l'enceinte par une inspiration suffisante. The bladder is placed by one end then slightly inflated so as to take its place by evacuating the trapped air between the bladder and the enclosure by sufficient inspiration.
La section droite du mandrin tubulaire peut etre de forme quelconque. The cross section of the tubular mandrel can be of any shape.
Ainsi, L'invention comporte Les avantages suivants : la liaison étanche de la vessie à L'enceinte est obtenue mécaniquement sans collage. Ainsi, la ves sie peut être re#irée'#t remplacée par une autre en cak de vieillissement. La fiabilité de L'étanchéité de
L'enceinte est assurée. Ces avantages sont obtenus en conservant une résistance égale ou supérieure à celle de L'acier avec une densité inférieure à 2.Thus, the invention has the following advantages: the sealed connection of the bladder to the enclosure is obtained mechanically without bonding. Thus, the bladder can be re # ired '# t replaced by another in aging cak. The reliability of the sealing of
The enclosure is insured. These advantages are obtained by retaining a resistance equal to or greater than that of steel with a density less than 2.
La fabrication peut être automatisée en série et permet de fabriquer économiquement des enceintes de formes et de dimensions variées comportant un ou plusieurs inserts ou embouts d'extrémité de Liai son. On peut y disposer une ou plusieurs vessies de manière à créer un échange de pression entre des fluides différents tels que L'huiLe et l'eau, par exemple, ou réalii ser un accumulateur oléopneumatique huile/azote, comme représenté sur la figure 6. The manufacturing can be automated in series and makes it possible to economically manufacture enclosures of various shapes and sizes comprising one or more Liai son inserts or end caps. One or more bladders can be placed there so as to create an exchange of pressure between different fluids such as oil and water, for example, or make an oil / nitrogen oleopneumatic accumulator, as shown in FIG. 6.
Sur cette figure, on reconnait l'ensemble de l'enceinte comprenant Les embouts 2, le mandrin 14 et la couche de matériau composite 16. Cette enceinte réalisée selon le procédé de L'invention comporte, intérieurement, deux vessies 106, étanches L'une vis-à-vis de L'autre. In this figure, we recognize the entire enclosure comprising the end pieces 2, the mandrel 14 and the layer of composite material 16. This enclosure produced according to the method of the invention comprises, internally, two bladders 106, watertight L ′ one opposite the other.
