Abstract

The tube has a central core (1) with a pair of shells (2, 3) fixed coaxially around it and assembled to each other, forming a closed external envelope. Preferred features: The central tube is circular, the shells semicircular. Each shell has internal radial ribs for rigidity, supported by and fixed onto the periphery of the central core, where complementary formations assist assembly. The shells are symmetrical, the ribs distributed at equal angles, such that following assembly, the cells formed are identical. The central core tube is entirely hollow. Longitudinal edges of the shells have complementary profiles for assembly and centering. The components are assembled using adhesive. Shells are formed by extrusion.

Description

ORGANE TUBULAIRE ET ALVEOLAIRE.TUBULAR AND ALVEOLAR BODY.

L'invention se rattache au secteur technique des mandrins d'enroulement, des ensouples et des structures portantes. Il est connu d'utiliser notamment mais non limitativement, dans le domaine des machines textiles, des organes tubulaires faisant office d'ensouple. Ces ensouples, plus généralement ces mandrins d'enroulement, doivent présenter des sections transversales très rigides, si l'on considère les forces de pression et autres, auxquels il sont soumis. Ces organes tubulaires doivent donc être suffisamment rigides pour ne pas être déformés. En outre, de tels organes tubulaires doivent être le plus léger possible, pour ne pas alourdir inutilement les parties de la machine les recevant, tout en facilitant leur  The invention relates to the technical sector of winding mandrels, beams and supporting structures. It is known to use in particular but not limited to, in the field of textile machines, tubular members acting as beam. These beams, more generally these winding mandrels, must have very rigid cross sections, if we consider the pressure and other forces to which they are subjected. These tubular members must therefore be rigid enough not to be deformed. In addition, such tubular members must be as light as possible, so as not to unnecessarily burden the parts of the machine receiving them, while facilitating their

transport, leur stockage et leur manipulation.  transport, storage and handling.

Pour concilier ces deux caractéristiques, rigidité, d'une part et légèreté, d'autre part, on a proposé de réaliser des organes tubulaires à structure alvéolaire, permettant ainsi de les réaliser dans des matériaux légers du type aluminium, matériau composite... Par exemple les organes tubulaires sont  To reconcile these two characteristics, rigidity, on the one hand, and lightness, on the other hand, it has been proposed to produce tubular members with honeycomb structure, thus making it possible to produce them in light materials of the aluminum type, composite material, etc. For example the tubular organs are

obtenus par extrusion au moyen de filières appropriées.  obtained by extrusion using appropriate dies.

Toutefois, cette structure du type alvéolaire limite le diamètre des  However, this structure of the alveolar type limits the diameter of the

organes tubulaires, sauf à utiliser des moyens de mise en oeuvre très onéreux.  tubular members, except when using very expensive means of implementation.

C'est ainsi que les diamètres de ces organes tubulaires de structures alvéolaires sont généralement limités à 250 mm par exemple. Or, pour certaines  This is how the diameters of these tubular members of cellular structures are generally limited to 250 mm for example. However, for some

applications, il est nécessaire d'utiliser des mandrins, ensouples ou autres  applications, it is necessary to use chucks, beams or other

structures tubulaires porteuses, de diamètre plus important.  load-bearing tubular structures, of larger diameter.

Le problème que se propose de résoudre l'invention est de pouvoir réaliser des organes tubulaires du type alvéolaire suffisamment rigides et relativement légers, de diamètre important, pouvant atteindre 600 mm par exemple, tout en ayant pour objectif de ne pas augmenter de manière importante, les coûts de production. Autrement dit, le problème que se propose de résoudre l'invention, est de pouvoir obtenir un organe tubulaire du type alvéolaire qui soit rigide, léger, de diamètre important et d'un coût de revient réduit. Pour résoudre un tel problème, il a été conçu et mis au point un organe tubulaire de structure transversale du type alvéolaire qui comprend un noyau central sur lequel sont fixées périphériquement et coaxialement au moins deux coquilles nervurées, assemblées entre elles pour constituer une enveloppe  The problem which the invention proposes to solve is to be able to produce tubular members of the cellular type sufficiently rigid and relatively light, of large diameter, up to 600 mm for example, while having the objective of not increasing significantly, production costs. In other words, the problem which the invention proposes to solve is to be able to obtain a tubular member of the cellular type which is rigid, light, of large diameter and of reduced production cost. To solve such a problem, it has been designed and developed a tubular member of transverse structure of the alveolar type which comprises a central core on which are fixed peripherally and coaxially at least two ribbed shells, assembled together to form an envelope

externe fermée.external closed.

Compte tenu du problème posé d'une application particulièrement visée mais non limitative à un mandrin d'enroulement, ensouple, le noyau central est  Given the problem posed of a particularly targeted but non-limiting application to a winding mandrel, beam, the central core is

un tube de section circulaire, les coquilles étant de section semi circulaire.  a tube of circular section, the shells being of semi circular section.

Pour résoudre le problème posé d'obtenir une structure du type alvéolaire chaque coquille présente au moins une nervure interne de rigidité formée radialement et apte à prendre appui sur la périphérie du noyau central  To solve the problem of obtaining a structure of the alveolar type, each shell has at least one internal rib of rigidity formed radially and capable of bearing on the periphery of the central core

en y étant fixées.by being attached to it.

Pour résoudre le problème posé d'assurer l'assemblage des coquilles externes par rapport au noyau central, les zones d'appui des nervures et du  To solve the problem posed of ensuring the assembly of the external shells relative to the central core, the bearing zones of the ribs and of the

A partir de cette conception de base, soit le tube constituant le noyau central est totalement creux, soit le tube est de section transversale du type alvéolaire. Pour résoudre le problème posé d'améliorer la fixation des coquilles entre elles, les extrémités des coquilles présentent des profilés complémentaires  From this basic design, either the tube constituting the central core is completely hollow, or the tube is of cross-section of the cellular type. To solve the problem posed of improving the fixing of the shells therebetween, the ends of the shells have complementary profiles

Selon l'invention, l'organe tubulaire de structure alvéolaire, comprend un noyau central (1) sur lequel sont fixés périphériquement et coaxialement, au moins deux coquilles nervurées (2) et (3). Les coquilles (2) et (3) sont assemblées entre elles pour constituer une enveloppe externe fermée et sont disposées coaxialement au noyau central (1). La section transversale du noyau (1) et de l'enveloppe externe constituée par l'assemblage des coquilles (2) et (3) sont de même forme géométrique. Avantageusement, ces sections  According to the invention, the tubular member of cellular structure, comprises a central core (1) on which are peripherally and coaxially fixed, at least two ribbed shells (2) and (3). The shells (2) and (3) are assembled together to form a closed external envelope and are arranged coaxially with the central core (1). The cross section of the core (1) and of the external envelope formed by the assembly of the shells (2) and (3) are of the same geometric shape. Advantageously, these sections

transversales sont circulaires.transverse are circular.

Le noyau central (1) est ainsi constitué par un tube de section ronde, chacune des coquilles (2) et (3) étant de section semi circulaire. Cette forme géométrique de l'ensemble est particulièrement adaptée pour une application de l'organe tubulaire en tant qu'organe d'entraînement ou dent ensouple. On n'exclut pas, pour d'autres applications, de réaliser l'organe tubulaire alvéolaire de section transversale autre que circulaire, par exemple, du type polygonale. Chacune des coquilles (2) et (3) présente au moins une nervure interne de rigidité (2a) (3a) formée radialement et perpendiculairement aux  The central core (1) is thus constituted by a tube of round section, each of the shells (2) and (3) being of semi-circular section. This geometric shape of the assembly is particularly suitable for an application of the tubular member as a drive member or beam tooth. It is not excluded, for other applications, to produce the alveolar tubular member of cross section other than circular, for example, of the polygonal type. Each of the shells (2) and (3) has at least one internal rib of rigidity (2a) (3a) formed radially and perpendicular to the

génératrices desdites coquilles (2) et (3).  generating said shells (2) and (3).

Dans l'exemple illustré, chaque coquille (2) et (3) présente respectivement trois nervures (2a) (2b) (2c) et (3a) (3b) (3c). Les nervures (2a) et (3a) sont formées en bout de l'une des extrémités des coquilles correspondantes (2) et (3). Ainsi, dans cette forme de réalisation, les deux coquilles (2) et (3) sont symétriques, de sorte qu'après montage des coquilles par rapport au noyau central (1), les nervures (2a) et (3a) sont diamétralement opposées. Toujours dans l'exemple illustré, l'enveloppe extérieur de l'organe  In the example illustrated, each shell (2) and (3) respectively has three ribs (2a) (2b) (2c) and (3a) (3b) (3c). The ribs (2a) and (3a) are formed at the end of one of the ends of the corresponding shells (2) and (3). Thus, in this embodiment, the two shells (2) and (3) are symmetrical, so that after mounting the shells relative to the central core (1), the ribs (2a) and (3a) are diametrically opposite . Still in the example illustrated, the outer envelope of the organ

tubulaire alvéolaire est constituée par deux coquilles (2) et (3) demi circulaire.  alveolar tubular consists of two semi-circular shells (2) and (3).

1 5 Les extrémités des coquilles (2) et (3) présentent, le long de leurs bords longitudinaux, des profils complémentaires d'assemblage et de centrage (2d)  1 5 The ends of the shells (2) and (3) have, along their longitudinal edges, complementary assembly and centering profiles (2d)

(3d) et (2e) (3e) du type mâle - femelle.  (3d) and (2e) (3e) of the male - female type.

On note également que les extrémités libres des différentes nervures de rigidité (2a) (2b) (2c) et (3a) (3b) (3c) de chacune des coquilles présentent des  We also note that the free ends of the different stiffness ribs (2a) (2b) (2c) and (3a) (3b) (3c) of each of the shells have

agencements d'appui et d'assemblage avec la périphérie du tube central (1).  support and assembly arrangements with the periphery of the central tube (1).

Dans l'exemple illustré, ces agencements peuvent être constitués par des talons d'appui (3al) (3bl) (3cl) et (2al) (2bl) et (3cl) délimitant un évidemment interne pour le logement d'un produit d'assemblage tel que de la colle (figure  In the example illustrated, these arrangements can be constituted by support heels (3al) (3bl) (3cl) and (2al) (2bl) and (3cl) delimiting an internal recess for the housing of a product of assembly such as glue (figure

4).4).

Une conception inverse peut être envisagée. Par exemple, comme le montre la figure 5, le tube central (1) peut présenter en débordement de sa périphérie externe, une série de nervures parallèles (la) (lb), orientées selon ses génératrices, et entre lesquelles sont logées les différentes nervures de rigidité de chacune des coquilles (2) et (3). A titre indicatif, nullement limitatif, le tube central (1) peut être en carbone, tandis que chacune des demi coquilles (2) et (3) peuvent être réalisées par extrusion d'un profilé aluminium. L'assemblage des différents éléments constitutifs de l'organe tubulaire alvéolaire, selon les caractéristiques de l'invention, peut être effectué par tout moyen connu et approprié. Par exemple, les coquilles (2) et (3) sont assemblées sur le tube (1) par pressage et par collage. De même, l'assemblage des coquilles (2) et (3), peut être effectué par  A reverse conception can be envisaged. For example, as shown in FIG. 5, the central tube (1) may have, overflowing from its external periphery, a series of parallel ribs (la) (lb), oriented according to its generatrices, and between which the different ribs are housed. stiffness of each of the shells (2) and (3). As an indication, in no way limiting, the central tube (1) can be made of carbon, while each of the half-shells (2) and (3) can be produced by extruding an aluminum profile. The assembly of the various constituent elements of the alveolar tubular member, according to the characteristics of the invention, can be carried out by any known and appropriate means. For example, the shells (2) and (3) are assembled on the tube (1) by pressing and by gluing. Likewise, the assembly of the shells (2) and (3) can be carried out by

collage, soudage...bonding, welding ...
