Abstract
Description
La présente invention concerne un accumulateur hydropneumatique composé d'une enveloppe à l'intérieur de laquelle est montée de manière étanche une membrane séparant l'enveloppe en une première chambre contenant du liquide et une deuxième chambre contenant du gaz, l'enveloppe présentant un premier orifice de remplissage en liquide et un deuxième orifice de remplissage en gaz (par exemple de l'azçte). The present invention relates to a hydropneumatic accumulator composed of an envelope inside which is sealingly mounted a membrane separating the envelope into a first chamber containing liquid and a second chamber containing gas, the envelope presenting a first liquid filling port and a second gas filling port (for example azçte).
Dans les accumulateurs hydropneumatiques de ce genre, l'orifice de remplissage en gaz est généralement#ob- turé soit par un bouchon vissé sur l'enveloppe avec interposition éventuelle d'un joint d'étanchéité, soit par un bouchon plat soudé sur une face plane de l'enveloppe, soit encore par un bouchon de soudure.In hydropneumatic accumulators of this kind, the gas filling orifice is generally # closed either by a plug screwed on the casing with possible interposition of a seal, or by a flat plug welded on one side plane of the envelope, or again by a solder plug.
L'accumulateur dans lequel l'orifice de remplissage en gaz est obturé par un bouchon soudé, est caractérisé en ce que le bouchon est constitué par une bille de diamètre supérieur au diamètre de l'orifice, la bille étant soudée à l'extrémité extérieure de cet orifice. The accumulator in which the gas filling orifice is closed by a welded plug, is characterized in that the plug consists of a ball of diameter greater than the diameter of the orifice, the ball being welded at the outer end from this hole.
La bille d'obturation peut être très légère et réalisée en acier doux ordinaire. Elle est d'une mise en oeuvre très simple puisqu'elle ne comporte pas de conditions géométriques et ne nécessite pas un état de surface particulièrement soigné, contrairement à ce qui est le cas du bouchon plat.The shutter ball can be very light and made of ordinary mild steel. It is of a very simple implementation since it does not include geometric conditions and does not require a particularly neat surface condition, unlike what is the case of the flat plug.
La présente invention concerne également un dispositif pour assurer le soudage de la bille sur l'orifice de remplissage de l'accumulateur.The present invention also relates to a device for ensuring the welding of the ball on the filling orifice of the accumulator.
Ce dispositif destiné à être associé à un support et à une tête de gonflage entre lesquels peut être placé un accumulateur, est caractérisé en ce qu'il comprend un dispositif d'alimentation automatique en billes commandé par un signal de fin de gonflage et propre à délivrer les billes une par une dans une portion tronconique de l'ouverture de la tête de gonflage, et un dispositif de soudage comprenant une broche montée coulissante par rapport à la tête de gonflage, propre à venir en contact avec la bille se trouvant dans ladite portion conique et connectée à l'un des pôles d'une source de courant dont l'autre pôle est connecté à la tête, de sorte que, lorsque la broche vient au contact de la bille, le circuit électriqueestfermé et que la bille et le bord de l'orifice de remplissage sont portés à blanc, et des moyens pour appliquer ensuite un effort longitudinal sur la broche de manière à assurer le soudage de la bille sur le bord de l'orifice.This device intended to be associated with a support and with an inflation head between which an accumulator can be placed, is characterized in that it comprises an automatic ball feeding device controlled by an end of inflation signal and suitable for deliver the balls one by one into a frustoconical portion of the opening of the inflation head, and a welding device comprising a spindle slidably mounted relative to the inflation head, suitable for coming into contact with the ball located in said conical portion and connected to one of the poles of a current source, the other pole of which is connected to the head, so that, when the pin comes into contact with the ball, the electrical circuit is closed and the ball and the edge of the filling orifice are brought to white, and means for then applying a longitudinal force on the spindle so as to ensure the welding of the ball on the edge of the orifice.
Le dispositif d'alimentation en billes comprend de préférence un corps dans lequel peuvent coulisser de manitre étanche deux tiroirs solidaires l'un de l'autre par l'intermédiaire d'un étrier, écartés l'un de l'autre d'une distance approximativement égale au diamètre de la bille, et pouvant venir à volonté en regard d'un conduit d'alimentation en billes relié à une trémie ou en regard d'un conduit relié à la portion tronconique de l'ouverture de la tête de gonflage, et des moyens pour déplacer dans le corps l'ensemble des deux tiroirs.The bead feeding device preferably comprises a body in which two drawers integral with one another can slide in leak-tight manner by means of a stirrup, spaced apart from each other by a distance approximately equal to the diameter of the ball, and being able to come at will opposite a ball supply duct connected to a hopper or opposite a duct connected to the frustoconical portion of the opening of the inflation head, and means for moving the assembly of the two drawers in the body.
On a décrit ci-apres, à titre d'exemple non limitatif, un mode de réalisation de l'accumulateur et du dispositif de soudage selon l'invention avec référence à la
Figure Unique du dessin annexé qui est une vue en coupe de l'accumulateur et du dispositif de soudage.An embodiment of the accumulator and of the welding device according to the invention has been described below, by way of nonlimiting example.
Unique figure of the accompanying drawing which is a sectional view of the accumulator and the welding device.
Au dessin, on voit un accumulateur hydropneumatique qui est désigné au dessin d'une façon générale par la référence 1. Cet accumulateur #comporte une enveloppe 2 à l'intérieur de laquelle une membrane 3 est montée de manière étanche. Cette membrane sépare l'intérieur de l'enveloppe 2 en une première chambre 4 contenant de liquide et une seconde chambre 5 contenant du gaz et présentant un orifice de remplissage en gaz 6; cet orifice est fermé par une bille 7 dont le diamètre est supérieur à celui de l'orifice 6 et qui est soudée sur l'extrémité extérieure de.cet orifice.In the drawing, we see a hydropneumatic accumulator which is generally designated in the drawing by the reference 1. This accumulator # comprises a casing 2 inside which a membrane 3 is mounted in leaktight manner. This membrane separates the interior of the envelope 2 into a first chamber 4 containing liquid and a second chamber 5 containing gas and having a gas filling orifice 6; this orifice is closed by a ball 7 whose diameter is greater than that of the orifice 6 and which is welded to the outer end of this orifice.
Le soudage de la bille 7 sur l'enveloppe 2 est assuré alors que l'accumulateur 1 est serré entre un support 8 et une tête de gonflage 9 qui est fixée au support par trois tirants 10 en appui sur des canons isolants li Cette tête 9 comporte un alésage 12 dont la partie inférieure 13 est tronconique.Welding of the ball 7 on the casing 2 is ensured while the accumulator 1 is clamped between a support 8 and an inflation head 9 which is fixed to the support by three tie rods 10 bearing on insulating barrels li This head 9 has a bore 12 whose lower part 13 is frustoconical.
Dans l'alésage 12 est disposé un fourreau 14 en matiere isolante, comportant des joints d'étanchéité 15 et 16, qui est solidaire de la tête et contient une broche coulissante 17; 1 'extrémité de cette broche présente un évidement sphérique 17a sensiblement au diamètre de labille 7. In the bore 12 is disposed a sheath 14 of insulating material, comprising seals 15 and 16, which is integral with the head and contains a sliding pin 17; The end of this pin has a spherical recess 17a substantially at the diameter of the lip 7.
Sous l'action d'un ressort 18, cette broche est en butée sur le fourreau 14 par l'intermédiaire d'un segment d'arrêt 19; elle comprend à sa partie haute une tresse 20 d'amenée du courant électrique. De son côté la partie supérieure de la tête de gonflage 9 est connectée à une tresse 21 pour le retour du courant.Under the action of a spring 18, this pin is in abutment on the sleeve 14 by means of a stop segment 19; it comprises at its upper part a braid 20 for supplying the electric current. For its part, the upper part of the inflation head 9 is connected to a braid 21 for the return of the current.
L'alésage 12 est relié par un raccord 22 et une conduite 23 une bouteille 24 qui comporte un robinet 25 et un manomètre 26. Sur la conduite de liaison 23, un détendeur 28 permet d'ajuster la. pression de gonflage désirée que l'on peut lire sur un manomètre 29. Un robinet 30 permet de couper l'alimentation et un second robinet 31 permet d'obtenir la mise à l'atmosphère de l'alésage 12.Un peu plus haut dans cet alésage débouche un conduit 32 d'alimentation automatique des billes raccordé un corps de distributeur 33 muni de deux éléments d'étanchéité 34 et 35 et dans lequel sont montés coulissants deux deux tiroirs 36 et 37 écartés l'un de l'autre d'une distance approximativement égale au diamètre d'une bille 7 et solidarisés l'un a l'autre par un étrier 38, qu'un ressort 39 prenant appui sur une butée 40 met en butée sur le corps.The bore 12 is connected by a connector 22 and a pipe 23 to a bottle 24 which includes a tap 25 and a pressure gauge 26. On the connecting pipe 23, a pressure regulator 28 makes it possible to adjust the. desired inflation pressure which can be read on a pressure gauge 29. A tap 30 makes it possible to cut off the supply and a second tap 31 makes it possible to vent the bore 12. A little higher in this bore opens a conduit 32 for automatic supply of the balls connected to a distributor body 33 provided with two sealing elements 34 and 35 and in which two two drawers 36 and 37 are slidably mounted spaced from one another a distance approximately equal to the diameter of a ball 7 and secured to one another by a stirrup 38, which a spring 39 bearing on a stop 40 abuts on the body.
Un noyau 41 solidarisé l'étrier 38, peut coulisser dans un électro-aimant 42. Une trémie 43 contenant des billes 7 est reliée au corps 33 du distributeur par un conduit 44.A core 41 secured to the stirrup 38, can slide in an electromagnet 42. A hopper 43 containing balls 7 is connected to the body 33 of the distributor by a conduit 44.
L'accumulateur 1 étant serré entre le support 2 et la tête de gonflage 9, on ouvre le robinet 25 et on lit sur le manomètre 26 la pression de l'azote contenue dans la bouteille 24. Il faut que cette pression soit supérieure à la pression de gonflage désirée, sinon on change la bouteille. Cette pression de gonflage, que l'on peut lire sur le manomètre 29, s'obtient en manipulant le détendeur 28. Ensuite on ouvre le robinet 30 et le gonflage s'effectue jusqu'à stabilisation des manomètres 29 et 27 à la meme pression.The accumulator 1 being clamped between the support 2 and the inflation head 9, the tap 25 is opened and the pressure of the nitrogen contained in the bottle 24 is read on the pressure gauge 26. This pressure must be greater than the desired inflation pressure, otherwise the bottle is changed. This inflation pressure, which can be read on the pressure gauge 29, is obtained by manipulating the regulator 28. Then the valve 30 is opened and the inflation takes place until the pressure gauges 29 and 27 stabilize at the same pressure .
L'opération de gonflage étant terminée, un signal, qui peut être délivré pa. la pression, actionne l'électro-aimant 42 qui repousse le noyau 41, lui-même entraînant l'étrier 38 et les deux tiroirs 36 et 37, ainsi que la bille 7 logée entre eux. La course de l'étrier est limitée par la butée 40. L'azote n'a pas pu s'échapper car le tiroir 36 a fermé le conduit 44 de la trémie, avant que le tiroir 37 n'ouvre lc conduit 32; la bille.tombe dans la tête de gonflage 9 et, guidée par le cône 13, vient se placer sur le trou 6.The inflation operation being completed, a signal, which can be delivered pa. pressure, activates the electromagnet 42 which repels the core 41, itself driving the stirrup 38 and the two drawers 36 and 37, as well as the ball 7 housed therebetween. The stirrup stroke is limited by the stop 40. The nitrogen could not escape because the drawer 36 closed the duct 44 of the hopper, before the drawer 37 opened the duct 32; the ball falls into the inflation head 9 and, guided by the cone 13, is placed on the hole 6.
Le distributeur de billes reprend ensuite sa position initiale.The ball dispenser then returns to its initial position.
La broche 17 descend et vient en appui sur la bille 7,
Le circuit électrique est de ce fait fermé et le courant électrique arrive par la tresse 20, passe par la broche 17 et traverse la bille 7; le retour du courant s'effectue par la tête de gonflage 9 et la tresse 21. Au passage du courant la zone de contact de la bille et le bord du trou sont portés au blanc soudant.The spindle 17 descends and comes to bear on the ball 7,
The electric circuit is therefore closed and the electric current arrives through the braid 20, passes through the pin 17 and passes through the ball 7; the return of the current is effected by the inflation head 9 and the braid 21. When the current passes, the contact zone of the ball and the edge of the hole are brought to welding white.
A ce moment, on applique un effort longitudinal F. à la broche 17, ce qui permet la soudure de la bille sur le trou de façon étanche. On ferme ensuite le robinet 30 et on ouvre le robinet 31, de façon à évacuer l'azote restant dans la tête de gonflage, le manomètre 27 indiquant 0. On peut alors enlever le bloc pneumatique du poste de gonflage et de soudure. At this time, a longitudinal force F. is applied to the pin 17, which allows the ball to be welded to the hole in a sealed manner. The valve 30 is then closed and the valve 31 is opened, so as to remove the nitrogen remaining in the inflation head, the pressure gauge 27 indicating 0. The pneumatic unit can then be removed from the inflation and welding station.
Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
