Definitions
- the field of the invention is that of the design and manufacture of equipment for the heat treatment of metal parts.
- the invention relates to a device for handling and holding a part during a heat treatment in a vertical furnace.
- the parts are held in position on holding devices that allow their handling for their entry into an oven prior to the heat treatment, and their output from the oven, after the heat treatment.
- Such holding devices are widely used and comprise a lifting column and a star support integral with the lifting column.
- the star support has arms integral with a hub on which the parts to be treated rest.
- the lifting column also comprises handling keys which allow, via ad-hoc means, to move the holding device.
- the star supports are in one piece and formed by pouring into a mold a liquid metal material which hardens on cooling.
- the star supports according to this first embodiment have a high mechanical strength but remain bulky and are not repairable, or with difficulty, especially in case of premature wear or breakage of one of the arms.
- star supports can not be adapted to different geometries of parts.
- the size of the molds can be large depending on the size of the star support to be manufactured. Therefore, a mold for the manufacture of a support large star has a large size and weight, which makes handling difficult at the expense of production rates and costs.
- the holding devices comprising one or more star supports according to this second embodiment have the advantage of being simpler to manufacture.
- the star supports according to the second embodiment can not be adapted to pieces of different geometries.
- the separation of the arms of the hub causes degradation of the arm and the hub. Since the welding of the arms on the hub results from a material melting of the arms and the hub, the separation which consists in removing the weld bead causes a removal of material at least for the arms.
- the disengaged arms are then unusable since their mechanical strength is reduced because of the removal of material.
- the invention also aims to provide such a holding device that can be adapted to different dimensions and geometries of parts.
- the invention further aims to provide such a device that is simple and quick to repair in case of wear or breakage of arms.
- the manufacture of a holding device according to the invention is thus simplified. Indeed, the different parts of the device can be manufactured independently of each other, quickly, and their assembly is both simple and achievable in a reduced time.
- connection between the arms and the hub is more efficient than in the prior art since the clevises allow a better recovery of the mechanical forces on the arms.
- each arm has a protruding lug intended to fit into a complementary shaped reserve to that of the lug, made between the two ears of the yoke.
- the lug and the reserve together form a first locking in position of the arm relative to the hub.
- the first blocking means are in the form of a light made in the arm and the second locking means are in the form of a bore made on the two ears of the yoke, the light and the holes being intended to come opposite one another and to be crossed by a fastening member.
- the mounting and holding of the arms in position in the yokes can be achieved quickly and simply. Furthermore, thanks to the interlocking of the arm in the yoke, the lights and holes are directly opposite each other, which facilitates all the more the insertion of the fasteners.
- the securing member is a pin intended to be fixed on one of the ears of the yoke.
- the pin is fixed on one of the ears by means of a ring welded to said ear.
- the lifting column carries handling keys, the keys being advantageously removable relative to the lifting column.
- the keys allow, by ad-hoc means, to manipulate the device for holding parts. Moreover, their independence vis-à-vis the lifting column facilitates the mounting of one or more star supports on the lifting column.
- each arm has a cross section I.
- the cross section in I ensures good mechanical resistance to stress.
- the arms are thus better able to withstand the weight of the parts, especially when lifting the device loaded with the parts to be treated thermally, the parts resting only on the arms of the star support.
- the support comprises four arms regularly spaced from each other.
- the presence of four arms ensures a good distribution of efforts related to the support of parts. Moreover, these arms can help facilitate the proper positioning of the device in the oven during the heat treatment.
- the device comprises two star supports superimposed one on the other along the lifting column.
- fixed is meant that the star support 3 is secured to the lifting column 2 in a reversible manner, that is to say that the star support 3 can be detached simply and quickly from the lifting column 2.
- the lifting column 2, illustrated on the figure 1 is in the form of a hollow metal tube extending along a first axis A1.
- the column 2 has a slot 22 for receiving the lifting key 4 (shown only on the figure 1 ), and at a lower end 23, opposite the upper end 21, at least six pins 24 on which is intended to rest the support 3 star.
- the hub 31 comprises a central cylinder 311.
- the central cylinder 311 has, at mid-height, an inner bead 312 which defines a first bearing surface 313 and a second bearing surface 314 intended to rest, one or the other on the pins 24 of the column 2 lifting.
- This bead 312 allows in particular to mount the support 3 star in one direction or the other, reversibly, turning regularly. This allows in particular to compensate for the deformations of the arms 32 resulting from the weight of the parts.
- the support 3 star comprises four arms 32 extending outwardly of the hub 31 to form the star.
- a star support 3 may in particular comprise up to nine arms 322.
- the four arms 32 are regularly spaced from each other, in this case at 90 ° from each other.
- the star support 3 also comprises clevises 34 for attaching the arms 32 to the hub 31.
- each clevis 34 extends from the central cylinder 311 towards the outside of the support 3, and is spaced from the other clevises 34 by 90 ° in accordance with the arrangement of the arms 32 at 90 ° from each other.
- each yoke 34 is formed by two lugs 341 extending outwardly of the hub 31.
- the hub 31 thus comprises four yokes 34 in each of which an arm 32 is mounted.
- Each yoke 34 has means for retaining the arms 32 on the hub 31.
- the cylinder 311 of the hub 31 comprises in each yoke 34 a reserve 315 which forms an external cavity opening towards the outside of the hub 31, the cavity being situated between the two lugs 341 of the yoke 34.
- the arms 32 as illustrated on the figures 1 , 2 and 3 , have an I-shaped section composed of an upper sole 321 and a lower sole 322 joined to each other by a central core 323.
- Each arm 32 has a first end 324 in the form of an arrow or tip defining in a distal portion of lower height, a lug 325 intended to be fitted into the reserve 315 of the yoke 34 along the second axis A2, which is then, for each arm 32, an insertion axis of the arm 32 in a yoke 34.
- the lugs 325 and the reserves 315 have a complementary shape so as to limit the clearance between the arm 32 and the hub 31 once the arm is mounted in a yoke 34.
- each arm 32 also has first locking means 326 intended to cooperate with second locking means 342 (visible on the figure 1 ) integral with the yoke 34 in which the arm 32 is mounted, to lock the arm 32 in translation along the second axis A2.
- first locking means 326 are in the form of a slot formed in the arm 32, and more particularly in the web 323 of the arm 32, and the second locking means 342 are in the form of a hole made on each lug 341 of the yoke 34 in which the arm 32 is inserted.
- the light and the holes are thus intended to come face to each other and to be traversed by a fastening member 33.
- the light of the first blocking means 326 is formed in portions projecting from either side of the core 323.
- the fastening member 33 which passes through the lumen of the arm 32 and the holes of the yoke 34 are in the form of a pin intended to be fixed on one of the ears 341 of the yoke 34.
- the pin has a cylindrical rod 331 and a head 332 having a diameter greater than that of the rod 331 so as to form an insertion stop of the fastening member 33 in the hole and holes.
- Fixing the pin on one of the lugs 341 is in particular carried out by means of a ring 35 welded to said lug 341 and on the end of the cylindrical rod 331 of the fastening member 33.
- the securing member 33 can not be removed easily, unless to suppress the weld performed.
- the star support 3 is assembled by inserting into each yoke 34 an arm 32 so that the lug 325 of each arm 32 comes to fit into the reserve 315 of each yoke 34.
- a securing member 33 is inserted in the bore of a first lug 341 of the yoke 34 and then in the lumen of the arm 32 and finally in the second piercing of the second ear 341 of the yoke 34, then the ring 35 is inserted around the pin 331 pin and welded thereto and the yoke 34. This operation is performed for each arm 32.
- the rings 35 could be welded to the pins so that in case of replacement of an arm 32, the ring 35 and the pin are wear parts replaced at each arm change 32.
- the arms 32 When the arms 32 are mounted and the securing members 33 are welded, the arms 32 are locked relative to the yokes 34, so that no translation and no rotation along the first axis A1, the second axis A2 or the third axis A3 is not allowed.
- the star support 3 When the star support 3 is completely built, it is inserted on a lifting column 2 so that the lifting column 2 passes through the cylinder 311 of the hub 31 until one of the bearing surfaces 313, 314 of the cylinder 311 comes to rest on each pin 24 of the column 2 lifting.
- the second star support 3 may have arms 32 having larger dimensions in length, that is to say along the axis of insertion of the arms 32 in the yokes 34, relative to the arms of the first star support 3 .
- the two star supports 3 are separated by a spacer 30 as illustrated in FIG. figure 4 .
- the key 4 of manipulation is force-fitted in the slot 22 of the lifting column 2 so as to promote the connection between the key 4 and the column 2.
- the key 4 allows the holding device 1 to be grasped by an ad-hoc tool to be inserted or taken out of a well-type furnace for the heat treatment of a part.
- the force fitting allows a good holding of the key 4 in the slot 22 of the column 2, the key 4 however remaining removable relative to the lifting column 2 to allow the addition or removal of supports 3 star.
- the lifting column 2, the hub 31, and the arms 32, as well as the securing member 33, the rings 35 and the key 4 are made of metal materials, preferably refractory steel, so as to allow their assembly by welding, their heat resistance during the heat treatment of the parts in a well-type furnace, and also to avoid any chemical reaction between the parts if they were composed of different materials.
- the holding device 1 according to the invention which has just been described, has many advantages including simplified manufacturing and mechanical strength more efficient than the holding devices of the prior art.
- the manufacture of the star support 3 from several assembled parts makes it possible on the one hand a high-speed production of the different parts by several different suppliers if necessary, and the assembly can be achieved simply and quickly by a technician.
- This embodiment also allows simplified maintenance of the holding devices 1 in that, if an arm 32 is damaged, it can be changed and replaced simply and quickly.
- a new arm 32 is then inserted until the lug 325 of said arm 32 is housed in the reserve 315 by interlocking, then the reinforcement member 33 is reinserted into the holes in the yoke 34 and the light of the new arm 32, and finally, the ring 35 is tightened to the securing member 33.
- the device 1 also makes it possible to adapt to pieces of different geometries. It is thus possible to propose a holding device 1 which comprises arms 32 of different lengths for the treatment of a first part and then to disassemble some of the arms to propose a holding device 1 having identical arms 32 for the treatment of a second part. .

Description
Le domaine de l'invention est celui de la conception et de la fabrication d'équipements pour le traitement thermique de pièces métalliques.The field of the invention is that of the design and manufacture of equipment for the heat treatment of metal parts.
Plus précisément, l'invention concerne un dispositif pour la manipulation et le maintien d'une pièce lors d'un traitement thermique dans un four vertical.More specifically, the invention relates to a device for handling and holding a part during a heat treatment in a vertical furnace.
Dans le domaine de l'invention, il est bien connu de soumettre des pièces métalliques à des opérations de traitement thermique tels que des cémentations, des recuits ou des trempes, afin d'accroître les propriétés mécaniques des pièces en question.In the field of the invention, it is well known to subject metal parts to heat treatment operations such as carburizing, annealing or tempering, in order to increase the mechanical properties of the parts in question.
Lors de ces traitements thermiques, les pièces sont maintenues en position sur des dispositifs de maintien qui permettent leur manutention pour leur entrée dans un four préalablement au traitement thermique, et leur sortie du four, postérieurement au traitement thermique.During these heat treatments, the parts are held in position on holding devices that allow their handling for their entry into an oven prior to the heat treatment, and their output from the oven, after the heat treatment.
De tels dispositifs de maintien sont largement répandus et comprennent une colonne de levage et un support en étoile solidaire de la colonne de levage. Le support en étoile présente des bras, solidaires d'un moyeu, sur lesquels reposent les pièces à traiter.Such holding devices are widely used and comprise a lifting column and a star support integral with the lifting column. The star support has arms integral with a hub on which the parts to be treated rest.
La colonne de levage comprend également des clavettes de manutention qui permettent, via des moyens ad-hoc, de déplacer le dispositif de maintien.The lifting column also comprises handling keys which allow, via ad-hoc means, to move the holding device.
Selon une première forme de réalisation, les supports en étoile sont monoblocs et formés par coulage dans un moule d'une matière métallique liquide qui durcit en refroidissant.According to a first embodiment, the star supports are in one piece and formed by pouring into a mold a liquid metal material which hardens on cooling.
Les supports en étoile selon cette première forme de réalisation présentent une résistance mécanique importante mais demeurent encombrants et ne sont pas réparables, ou difficilement, notamment en cas d'usure prématurée ou de casse de l'un des bras.The star supports according to this first embodiment have a high mechanical strength but remain bulky and are not repairable, or with difficulty, especially in case of premature wear or breakage of one of the arms.
Par ailleurs, les supports en étoile ne peuvent pas être adaptés selon des géométries différentes de pièces.In addition, the star supports can not be adapted to different geometries of parts.
Enfin, pour un moulage, le temps de refroidissement peut être important, ce qui rend la fabrication des dispositifs de maintien à la fois longue et coûteuse.Finally, for molding, the cooling time can be important, which makes the manufacture of holding devices both long and expensive.
Par ailleurs la taille des moules peut être imposante en fonction de la taille du support en étoile à fabriquer. Dès lors, un moule pour la fabrication d'un support en étoile de grande taille présente un encombrement et un poids importants, ce qui rend sa manipulation difficile au détriment des cadences et des coûts de production.Moreover, the size of the molds can be large depending on the size of the star support to be manufactured. Therefore, a mold for the manufacture of a support large star has a large size and weight, which makes handling difficult at the expense of production rates and costs.
Pour pallier ces inconvénients, une deuxième forme de réalisation de dispositifs de maintien a été développée.To overcome these disadvantages, a second embodiment of holding devices has been developed.
Dans cette deuxième forme de réalisation, les bras sont fabriqués indépendamment du moyeu puis soudés sur ce dernier pour former le dispositif de maintien.In this second embodiment, the arms are manufactured independently of the hub and then welded to the latter to form the holding device.
Tout en étant inférieure à celle de la première forme de réalisation, la tenue mécanique offerte par des supports en étoile selon la deuxième forme de réalisation permet néanmoins d'assurer un maintien des pièces lors de leur traitement thermique.While being lower than that of the first embodiment, the mechanical strength offered by star supports according to the second embodiment nevertheless allows to maintain the parts during their heat treatment.
Cela étant, les dispositifs de maintien comprenant un ou plusieurs supports en étoile selon cette deuxième forme de réalisation présentent l'avantage d'être plus simples de fabrication.However, the holding devices comprising one or more star supports according to this second embodiment have the advantage of being simpler to manufacture.
En effet, la fabrication des bras et du moyeu étant faite indépendamment, il est possible que ces pièces soient fabriquées à des cadences élevées et pour des coûts plus faibles.Indeed, the manufacture of arms and hub being made independently, it is possible that these parts are manufactured at high rates and for lower costs.
L'assemblage du support en étoile est alors réalisé par soudure des bras sur le moyeu.The assembly of the star support is then achieved by welding the arms on the hub.
Ainsi, en cas de casse ou d'usure d'un bras, on peut le désolidariser pour le remplacer par un bras neuf.Thus, in case of breakage or wear of an arm, it can be detached and replaced by a new arm.
Cependant, tout comme les supports en étoile selon la première forme de réalisation, les supports en étoile selon la deuxième forme de réalisation ne peuvent pas être adaptés à des pièces de géométries différentes.However, like the star supports according to the first embodiment, the star supports according to the second embodiment can not be adapted to pieces of different geometries.
En effet, la désolidarisation des bras du moyeu entraîne une dégradation des bras et du moyeu. Etant donné que la soudure des bras sur le moyeu résulte d'une fusion de matière des bras et du moyeu, la désolidarisation qui consiste à retirer le cordon de soudure entraîne un enlèvement de matière au moins pour les bras.Indeed, the separation of the arms of the hub causes degradation of the arm and the hub. Since the welding of the arms on the hub results from a material melting of the arms and the hub, the separation which consists in removing the weld bead causes a removal of material at least for the arms.
Les bras désolidarisés sont alors inutilisables puisque leur résistance mécanique est diminuée à cause du retrait de matière.The disengaged arms are then unusable since their mechanical strength is reduced because of the removal of material.
L'invention a notamment pour objectif de proposer un dispositif de maintien de pièces pour traitement thermique dans un four de type puits qui pallie les inconvénients de l'art antérieur.The object of the invention is notably to propose a device for holding parts for heat treatment in a well-type furnace which overcomes the disadvantages of the prior art.
Plus précisément, l'invention a pour objectif de proposer un dispositif de maintien qui soit plus rapide et moins coûteux à fabriquer que ceux de l'art antérieur.More specifically, the invention aims to provide a holding device that is faster and less expensive to manufacture than those of the prior art.
L'invention a également pour objectif de fournir un tel dispositif de maintien qui puisse être adapté à différentes dimensions et géométries de pièces.The invention also aims to provide such a holding device that can be adapted to different dimensions and geometries of parts.
L'invention a en outre pour objectif de fournir un tel dispositif qui soit simple et rapide à réparer en cas d'usure ou de casse des bras.The invention further aims to provide such a device that is simple and quick to repair in case of wear or breakage of arms.
Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints grâce à l'invention qui a pour objet un dispositif de maintien en position d'une pièce pour traitement thermique dans un four de type puits, comprenant :
- une colonne de levage s'étendant selon un premier axe ;
- au moins un support en étoile monté fixe sur la colonne de levage, le support en étoile comprenant :
- un moyeu monté sur la colonne ;
- au moins trois bras solidaires du moyeu et s'étendant vers l'extérieur du moyeu pour former une étoile,
- le moyeu comprend pour chaque bras, une chape formée par deux oreilles s'étendant vers l'extérieur du moyeu,
- chaque bras présente :
- une première extrémité destinée à être emboitée dans une chape selon un axe d'insertion,
- des premiers moyens de blocage destinés à coopérer avec des deuxièmes moyens de blocage solidaires de la chape pour bloquer le bras en translation selon l'axe d'insertion.
- a lifting column extending along a first axis;
- at least one fixed star support on the lifting column, the star support comprising:
- a hub mounted on the column;
- at least three arms integral with the hub and extending outwardly of the hub to form a star,
- the hub comprises for each arm, a yoke formed by two lugs extending towards the outside of the hub,
- each arm presents:
- a first end intended to be engaged in a yoke along an insertion axis,
- first locking means for cooperating with second blocking means secured to the yoke for locking the arm in translation along the axis of insertion.
La fabrication d'un dispositif de maintien selon l'invention est ainsi simplifiée. En effet, les différentes pièces du dispositif peuvent être fabriquées les unes indépendamment des autres, de manière rapide, et leur assemblage est à la fois simple et réalisable en un temps réduit.The manufacture of a holding device according to the invention is thus simplified. Indeed, the different parts of the device can be manufactured independently of each other, quickly, and their assembly is both simple and achievable in a reduced time.
Par ailleurs, la connexion entre les bras et le moyeu est plus performante que dans l'art antérieur puisque les chapes permettent une meilleure reprise des efforts mécaniques sur les bras.Moreover, the connection between the arms and the hub is more efficient than in the prior art since the clevises allow a better recovery of the mechanical forces on the arms.
De préférence, la première extrémité de chaque bras présente un ergot en saillie destiné à venir s'emboiter dans une réserve de forme complémentaire à celle de l'ergot, pratiquée entre les deux oreilles de la chape.Preferably, the first end of each arm has a protruding lug intended to fit into a complementary shaped reserve to that of the lug, made between the two ears of the yoke.
L'ergot et la réserve forment ensemble un premier blocage en position du bras par rapport au moyeu. Par ce premier assemblage, seule la translation selon l'axe d'insertion des bras reste possible, cette translation étant supprimée par les premiers moyens de blocage et les deuxièmes moyens de blocage.The lug and the reserve together form a first locking in position of the arm relative to the hub. By this first assembly, only the translation along the axis of insertion of the arms remains possible, this translation being suppressed by the first locking means and the second locking means.
Selon un mode de réalisation avantageux, les premiers moyens de blocage se présentent sous la forme d'une lumière pratiquée dans le bras et les deuxièmes moyens de blocage se présentent sous la forme d'un perçage pratiqué sur les deux oreilles de la chape, la lumière et les perçages étant destinés à venir en regard les uns des autres et à être traversés par un organe de solidarisation.According to an advantageous embodiment, the first blocking means are in the form of a light made in the arm and the second locking means are in the form of a bore made on the two ears of the yoke, the light and the holes being intended to come opposite one another and to be crossed by a fastening member.
Ainsi, le montage et le maintien des bras en position dans les chapes peut être réalisé de manière simple et rapide. Par ailleurs, grâce à l'emboîtement du bras dans la chape, les lumières et les perçages sont directement en regard les uns des autres, ce qui facilite d'autant plus l'insertion des organes de solidarisation.Thus, the mounting and holding of the arms in position in the yokes can be achieved quickly and simply. Furthermore, thanks to the interlocking of the arm in the yoke, the lights and holes are directly opposite each other, which facilitates all the more the insertion of the fasteners.
Avantageusement, l'organe de solidarisation est une goupille destinée à être fixée sur l'une des oreilles de la chape.Advantageously, the securing member is a pin intended to be fixed on one of the ears of the yoke.
Un tel organe est simple de réalisation et d'utilisation.Such an organ is simple to implement and use.
De préférence, la goupille est fixée sur l'une des oreilles au moyen d'une bague soudée sur ladite oreille.Preferably, the pin is fixed on one of the ears by means of a ring welded to said ear.
On permet ainsi de ne réaliser qu'un petit cordon de soudure au bénéfice de la consommation d'énergie pour la fabrication et de la simplicité et du coût de fabrication.It is thus possible to achieve a small weld bead for the benefit of energy consumption for manufacturing and simplicity and cost of manufacture.
Selon un mode de réalisation préféré, la colonne de levage porte des clavettes de manipulation, les clavettes étant avantageusement amovibles par rapport à la colonne de levage.According to a preferred embodiment, the lifting column carries handling keys, the keys being advantageously removable relative to the lifting column.
Les clavettes permettent, par des moyens ad-hoc, de manipuler le dispositif de maintien de pièces. Par ailleurs, leur indépendance vis-à-vis de la colonne de levage permet de faciliter le montage d'un ou de plusieurs supports en étoile sur la colonne de levage.The keys allow, by ad-hoc means, to manipulate the device for holding parts. Moreover, their independence vis-à-vis the lifting column facilitates the mounting of one or more star supports on the lifting column.
Selon un mode de réalisation particulièrement avantageux, chaque bras présente une section transversale en I.According to a particularly advantageous embodiment, each arm has a cross section I.
La section transversale en I permet d'assurer une bonne résistance mécanique aux contraintes. En effet, les bras résistent ainsi mieux au poids des pièces notamment lors du levage du dispositif chargé des pièces à traiter thermiquement, les pièces ne reposant que sur les bras du support en étoile.The cross section in I ensures good mechanical resistance to stress. In fact, the arms are thus better able to withstand the weight of the parts, especially when lifting the device loaded with the parts to be treated thermally, the parts resting only on the arms of the star support.
Avantageusement, le support comprend quatre bras régulièrement espacés les uns des autres.Advantageously, the support comprises four arms regularly spaced from each other.
La présence de quatre bras permet d'assurer une bonne répartition des efforts liés au support des pièces. Par ailleurs, ces bras peuvent permettre de faciliter le bon positionnement du dispositif dans le four lors du traitement thermique.The presence of four arms ensures a good distribution of efforts related to the support of parts. Moreover, these arms can help facilitate the proper positioning of the device in the oven during the heat treatment.
De préférence, le dispositif comprend deux supports en étoile superposés l'un sur l'autre le long de la colonne de levage.Preferably, the device comprises two star supports superimposed one on the other along the lifting column.
Il est ainsi possible de supporter plusieurs pièces à la fois sur un même dispositif de maintien ou, au contraire, de ne supporter qu'une seule pièce qui présente une géométrie particulière nécessitant plusieurs appuis.It is thus possible to support several pieces at a time on the same holding device or, on the contrary, to support only one piece which has a particular geometry requiring several supports.
D'autres caractéristiques et avantages de l'invention apparaîtront plus clairement à la lecture de la description suivante d'un mode de réalisation préférentiel de l'invention, donné à titre d'exemple illustratif et non limitatif, et des dessins annexés parmi lesquels :

Ce bourrelet 312 permet notamment de pouvoir monter le support 3 en étoile dans un sens ou dans l'autre, de manière réversible, en le retournant régulièrement. Cela permet notamment de compenser les déformations des bras 32 résultant du poids des pièces.This
Tel qu'illustré sur les
Selon une variante de réalisation non illustrée, un support 3 en étoile peut notamment comprendre jusqu'à neuf bras 322.According to an alternative embodiment not illustrated, a
Avantageusement, les quatre bras 32 sont régulièrement espacés les uns des autres, dans le cas présent à 90° les uns des autres.Advantageously, the four
Le support 3 en étoile comprend également des chapes 34, pour la fixation des bras 32 sur le moyeu 31.The
Plus précisément, chaque chape 34 s'étend depuis le cylindre central 311 vers l'extérieur du support 3, et est écartée des autres chapes 34 de 90° conformément à l'agencement des bras 32 à 90° les uns des autres.More specifically, each
En référence à la
Chaque chape 34 présente des moyens de retenue des bras 32 sur le moyeu 31.Each
Plus précisément, le cylindre 311 du moyeu 31 comprend dans chaque chape 34 une réserve 315 qui forme une cavité externe s'ouvrant vers l'extérieur du moyeu 31, la cavité étant située entre les deux oreilles 341 de la chape 34.More specifically, the
Les bras 32, tels qu'illustrés sur les
Chaque bras 32 présente une première extrémité 324 en forme de flèche ou de pointe définissant dans une partie distale de plus faible hauteur, un ergot 325 destiné à être emboîté dans la réserve 315 de la chape 34 selon le deuxième axe A2, qui est alors, pour chaque bras 32, un axe d'insertion du bras 32 dans une chape 34.Each
De préférence, les ergots 325 et les réserves 315 présentent une forme complémentaire de sorte à limiter le jeu entre le bras 32 et le moyeu 31 une fois que le bras est monté dans une chape 34.Preferably, the
Par ailleurs, chaque bras 32 présente également des premiers moyens de blocage 326 destinés à coopérer avec des deuxièmes moyens de blocage 342 (visibles sur la
Plus précisément, les premiers moyens de blocage 326 se présentent sous la forme d'une lumière pratiquée dans le bras 32, et plus particulièrement dans l'âme 323 du bras 32, et les deuxièmes moyens de blocage 342 se présentent sous la forme d'un perçage pratiqué sur chaque oreille 341 de la chape 34 dans lequel le bras 32 est inséré.More specifically, the first locking means 326 are in the form of a slot formed in the
La lumière et les perçages sont ainsi destinés à venir en regard les uns des autres et à être traversés par un organe 33 de solidarisation.The light and the holes are thus intended to come face to each other and to be traversed by a
De préférence, la lumière des premiers moyens de blocage 326 est pratiquée dans des portions faisant saillie de part et d'autre de l'âme 323.Preferably, the light of the first blocking means 326 is formed in portions projecting from either side of the
Ceci permet notamment d'offrir d'une part une bonne résistance au bras 32, face aux efforts mécaniques, et d'autre part, que chacune des portions faisant saillie de l'âme 323 vienne en appui sur une face intérieure 3411 d'une oreille 341 de la chape 34.This makes it possible in particular to offer, on the one hand, a good resistance to the
Ainsi, tous les jeux entre la chape 34 et le bras 32 sont supprimés.Thus, all the games between the
L'organe de solidarisation 33 qui traverse la lumière du bras 32 et les perçages de la chape 34 se présentent sous la forme d'une goupille destinée à être fixée sur l'une des oreilles 341 de la chape 34.The
Avantageusement, la goupille présente une tige 331 cylindrique et une tête 332 présentant un diamètre supérieur à celui de la tige 331 de sorte à former une butée d'insertion de l'organe de solidarisation 33 dans la lumière et les perçages.Advantageously, the pin has a
La fixation de la goupille sur l'une des oreilles 341 est notamment réalisée au moyen d'une bague 35 soudée sur ladite oreille 341 et sur l'extrémité de la tige 331 cylindrique de l'organe de solidarisation 33.Fixing the pin on one of the
Une fois soudé, l'organe de solidarisation 33 ne peut donc pas être retiré facilement, à moins de supprimer la soudure réalisée.Once welded, the securing
Le dispositif 1 de maintien selon l'invention est assemblé comme suit.The holding
Dans un premier temps on assemble le support 3 en étoile par insertion dans chaque chape 34 d'un bras 32 de sorte que l'ergot 325 de chaque bras 32 vienne s'emboîter dans la réserve 315 de chaque chape 34.In a first step, the
Lorsque le bras 32 est emboîté dans la chape 34, selon le deuxième axe A2 d'insertion du bras 32, un organe de solidarisation 33 est inséré dans le perçage d'une première oreille 341 de la chape 34 puis dans la lumière du bras 32 et enfin dans le deuxième perçage de la seconde oreille 341 de la chape 34, puis la bague 35 est insérée autour de la tige 331 goupille et soudée à cette dernière ainsi qu'à la chape 34. Cette opération est réalisée pour chaque bras 32.When the
Selon une variante de réalisation, les bagues 35 pourraient n'être soudées qu'aux goupilles de sorte qu'en cas de remplacement d'un bras 32, la bague 35 et la goupille soient des pièces d'usure remplacées à chaque changement de bras 32.According to an alternative embodiment, the
Ainsi, la désolidarisation de la bague 35 et de la goupille n'entraîne pas d'endommagement de la chape 34. La tenue mécanique du dispositif 1 est ainsi conservée.Thus, the disengagement of the
Lorsque les bras 32 sont montés et que les organes de solidarisation 33 sont soudés, les bras 32 sont bloqués par rapport aux chapes 34, de sorte qu'aucune translation et aucune rotation selon le premier axe A1, le deuxième axe A2 ou le troisième axe A3 ne soit autorisé.When the
Lorsque le support 3 en étoile est totalement construit, il est inséré sur une colonne 2 de levage de sorte que la colonne 2 de levage traverse le cylindre 311 du moyeu 31 jusqu'à ce l'une des surfaces d'appui 313, 314 du cylindre 311 vienne reposer sur chaque pion 24 de la colonne 2 de levage.When the
Le cas échéant, tel que cela est représenté sur la
Avantageusement, les deux supports 3 en étoile sont séparés par une entretoise 30 tel qu'illustré sur la
Lorsque le ou chaque support 3 en étoile est monté sur la colonne 2 de levage, la clavette 4 de manipulation est montée à force dans la fente 22 de la colonne 2 de levage de sorte à favoriser l'assemblage entre la clavette 4 et la colonne 2. La clavette 4 permet que le dispositif 1 de maintien soit saisi par un outillage ad-hoc pour être inséré ou sorti d'un four de type puits pour le traitement thermique d'une pièce.When the or each
Le montage à force permet une bonne tenue de la clavette 4 dans la fente 22 de la colonne 2, la clavette 4 restant toutefois amovible par rapport à la colonne 2 de levage pour permettre l'ajout ou le retrait de supports 3 en étoile.The force fitting allows a good holding of the key 4 in the
De préférence, la colonne 2 de levage, le moyeu 31, et les bras 32, ainsi que l'organe de solidarisation 33, les bagues 35 et la clavette 4, sont réalisés dans des matériaux métalliques, de préférence de l'acier réfractaire, de sorte à permettre leur assemblage par soudure, leur résistance à la chaleur lors du traitement thermique des pièces dans un four de type puits, et également de sorte à éviter toute réaction chimique entre les pièces si celles-ci étaient composées de différents matériaux.Preferably, the
Le dispositif 1 de maintien selon l'invention qui vient d'être décrit, présente de nombreux avantages parmi lesquels une fabrication simplifiée et une tenue mécanique plus performante que les dispositifs de maintien de l'art antérieur.The holding
En effet, la fabrication du support 3 en étoile à partir de plusieurs pièces assemblées permet d'une part une fabrication à cadences élevées des différentes pièces par plusieurs fournisseurs différents le cas échéant, et l'assemblage peut être réalisé de manière simple et rapide par un technicien.Indeed, the manufacture of the
En effet, il suffit au technicien d'insérer un bras 32 dans chaque chape 34 puis de souder l'organe de solidarisation 33 traversant les perçages de la chape 34 et la lumière du bras 32 de sorte à immobiliser et maintenir le bras 32 en position dans la chape 34.Indeed, it is sufficient for the technician to insert an
Ce mode de réalisation permet également une maintenance simplifiée des dispositifs 1 de maintien en ce que, si un bras 32 est détérioré, il peut être changé et remplacé de manière simple et rapide.This embodiment also allows simplified maintenance of the
Il suffit pour cela de dessouder la bague 35 de l'organe de solidarisation 33, de retirer l'organe de solidarisation 33, puis de retirer le bras 32 hors de la chape 34 selon son axe d'insertion.Suffice it to unsolder the
On insère alors un nouveau bras 32 jusqu'à ce que l'ergot 325 dudit bras 32 vienne se loger dans la réserve 315 par emboîtement, puis on réinsère l'organe de solidarisation 33 dans les perçages de la chape 34 et la lumière du nouveau bras 32, et enfin, on ressoude la bague 35 à l'organe de solidarisation 33.A
Enfin, le dispositif 1 permet également de s'adapter à des pièces de géométries différentes. On peut ainsi proposer un dispositif 1 de maintien qui comprend des bras 32 de différentes longueurs pour le traitement d'une première pièce puis démonter certains des bras pour proposer un dispositif 1 de maintien ayant des bras 32 identiques pour le traitement d'une deuxième pièce.Finally, the
