Abstract

It is characterised by stretching out the corrugations 5 of the end section of the tube forming, together with the braid 3 a double continuous lamellar metal partition clamped between the base of the end fitting 7 and the outer hooping ring 8 whilst the excessive part of the tube and sheath forms a metal mass whose fusion constitutes the circular assembly weld 12 of all the elements without a heterogenous range or any other added material. It is intended to allow these welds to be automated with a functional improvement in the speed of performing them as well as in the qualitative performance of the link between the various elements.

Description

Dispositif d'assemblage par soudure de raccords sur tuyauteries métalliques flexibles à profil ondulé. Device for assembling by welding fittings on flexible metallic pipes with corrugated profile.

Il est destiné à permettre une automatisation de ces soudures avec amélioration fonctionnelle de la rapidité d ' exécu- tion ainsi que de la performance qualitative de la liaison des différents éléments. It is intended to allow automation of these welds with a functional improvement in the speed of execution as well as in the qualitative performance of the connection of the various elements.

Jusqu'à ce jour l'assemblage des tuyaux métalliques flexibles à profil ondulé, s'exécutait d'une façon artisanale par des ouvriers hautement qualifiés pour assurer la soudure sur des génératrices d'ondes, des tresse et bague avec l'embout de raccordement. Les espaces intercalaires vides amorçaient des ruptures qui sous l'effet des torsions, vibrations ou autres détruisaient les étanchéités recherchées. Until now the assembly of flexible metal pipes with corrugated profile, was carried out in an artisanal way by highly qualified workers to ensure the welding on wave generators, braid and ring with the connecting piece . The empty intermediate spaces started ruptures which under the effect of twists, vibrations or others destroyed the sealing sought.

Le dispositif suivant l'invention rend la soudure plus facile, plus fiable et automatisable en un seul cordon de soudure tout en assurant un meilleur maintien des tresses métalliques permettant au flexible d ' arriver systèmatiquement aux pressions limites d'éclatement directement liées à leur tenue mécanique et sans que le diamètre d'écoulement de 1 ' ensemble ne soit réduit. The device according to the invention makes welding easier, more reliable and automated in a single weld bead while ensuring better retention of the metal braids allowing the hose to arrive systematically at the burst pressure limits directly linked to their mechanical strength. and without reducing the flow diameter of the assembly.

Il se caractérise par l'étirement des ondes du secteur terminal, du tube formant avec la tresse un double cloisonnement métallique lamellaire continu enserré entre la base de l'embout et la bague externe de cerclage alors que le dépassement des tube et gaine forme une masse métallique dont la fusion constitue la soudure d'assemblage circulaire de tous les éléments sans plage hétérogène ni autre apport. It is characterized by the stretching of the waves of the terminal sector, of the tube forming with the braid a double continuous metallic lamellar partitioning sandwiched between the base of the end piece and the external ring of strapping while the protrusion of the tube and sheath forms a mass metal whose fusion constitutes the circular assembly weld of all the elements without heterogeneous range or other contribution.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisations de l'objet de l'invention
La figure 1 est une vue en élévation avec partie coupée de l'assemblage des embout, tuyau et bague.
In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 is an elevational view with cutaway of the assembly of the nozzle, pipe and ring.

Les figures 2 et 3 représentent schématiquement le détail de formage du produit.  Figures 2 and 3 schematically represent the forming detail of the product.

Le dispositif comporte un embout de raccordement 1 relié au conduit formé par le tuyau annelé 2 recouvert par la tresse métallique 3, fig 1. The device comprises a connection end piece 1 connected to the conduit formed by the corrugated pipe 2 covered by the metal braid 3, fig 1.

Pour permettre l'assemblage automatisable performant sans micro retassures vides intercalaires ou joints présentant des amorces de rupture, on étire le secteur 4 (Fig 2) après avoir retiré la tresse 3 pour réaliser des surfaces rectilignes 5 (Fig 3). To allow efficient automated assembly without empty micro-shrinkage spacers or seals with incipient fractures, the sector 4 (Fig 2) is stretched after removing the braid 3 to make rectilinear surfaces 5 (Fig 3).

On remonte la tresse 3 jusqu'à l'arête 6 après avoir introduit la base 7 de l'embout 1, on cercle les deux surfaces 5, 3 par la bague 8. Le dépassement des arêtes 9, 10 formées par les surfaces métalliques concentriques jointives des tuyaux 5 et gaine 4 constituent une masse métallique 11, dont la fusion formera la soudure 12, assurant la liaison des tubes 2, tresse 3, embout 7 et bague 8. We go up the braid 3 to the edge 6 after having introduced the base 7 of the nozzle 1, we circle the two surfaces 5, 3 by the ring 8. The protrusion of the edges 9, 10 formed by the concentric metal surfaces contiguous pipes 5 and sheath 4 constitute a metallic mass 11, the fusion of which will form the weld 12, ensuring the connection of the tubes 2, braid 3, end piece 7 and ring 8.

Cette soudure est parfaitement homogène d'une étanchéité totale sans interstice ou espace pouvant affaiblir la structuration de l ' assemblage .  This weld is perfectly homogeneous with total tightness without gaps or spaces which could weaken the structuring of the assembly.

On améliore la compacité de la zone à souder tout en donnant à l'ensemble la conformation classique d'une soudure d'angle renforcée. The compactness of the area to be welded is improved while giving the whole the classic conformation of a reinforced corner weld.

De plus, les diamètres 13 et 14 des embout et tuyau ne sont pas diminués de sorte que le passage intégral des fluides est assuré. In addition, the diameters 13 and 14 of the nozzle and pipe are not reduced so that the complete passage of the fluids is ensured.

On diminue la fragilité de ce genre de soudure toujours aléatoire par la nature, l'éloignement des pièces du fait des ondulations et les défauts de positionnement en stabilisant les masses en présence. The fragility of this kind of weld, which is always random in nature, is reduced, the distance from the parts due to the undulations and the positioning faults are stabilized by stabilizing the masses present.

On économise les apports de soudure en utilisant le métal lui-même dont la fusion homogène, l'assemblage des bagues des tresses, des tuyaux et embouts qui constituent une masse monolithique et autorenforcée au point même où ont lieu les résultantes de forces destructives de torsion, flexion et autres. Welding is saved by using the metal itself, including homogeneous fusion, assembling the rings of the braids, pipes and fittings which constitute a monolithic and self-reinforcing mass at the very point where the results of destructive torsional forces take place. , bending and others.

On peut faire varier les dépassements pour augmenter ou diminuer la masse de métal de soudure et préparer un sertissage ultérieur. On supprime également le contrôle unitaire indis pensable jusqu'à ce jour, parùn contrôle aussi effacé sur pré lèvements.  The overruns can be varied to increase or decrease the mass of weld metal and prepare for subsequent crimping. It also removes the unit control essential to date, by which control also erased on direct debits.

Toutefois les formes, dimensions et dispositions des différents éléments, pourront varier dans la limite des équivalents, comme d ' ailleurs les matières utilisées pour leur fabrication, sans changer pour cela, la conception générale de 1 ' inven-
tion qui vient d' être décrite.
However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, like the materials used for their manufacture, without changing the general design of the invention for this.
