Description
Le domaine de l'invention est celui de la conception et de la fabrication des équipements de manutention. Plus précisément, l'invention concerne un panier de type assemblé, du type de ceux utilisés dans l'industrie, et en particulier mais non exclusivement destinés à être exposés au même traitement thermique que les pièces que le panier contient.The field of the invention is that of the design and manufacture of handling equipment. More specifically, the invention relates to an assembled type basket, of the type used in industry, and in particular but not exclusively intended to be exposed to the same heat treatment as the parts that the basket contains.
Dans le domaine de l'invention, il est courant d'utiliser des paniers métalliques pour le transport des pièces. De tels paniers sont notamment utilisés pour contenir une pluralité de pièces destinées à un traitement thermique, l'ensemble panier et pièces étant bien entendu placé dans l'équipement de traitement thermique.In the field of the invention, it is common to use metal baskets for transporting parts. Such baskets are used in particular to contain a plurality of parts for a heat treatment, basket and parts set being of course placed in the heat treatment equipment.
Les paniers utilisés sont essentiellement parallélépipédiques, et présentent donc une structure classique du type comprenant un fond à partir duquel s'étendent quatre parois verticales.The baskets used are essentially parallelepipedic, and therefore have a conventional structure of the type comprising a bottom from which extend four vertical walls.
Selon un premier type de réalisation des paniers destinés à ce type d'utilisation, les parois latérales sont soudées sur le fond, formant ainsi un panier indémontable.According to a first embodiment of the baskets intended for this type of use, the side walls are welded to the bottom, thus forming an indémontable basket.
Or, après quelques passages successifs dans l'équipement de traitement thermiques (et parfois après un seul passage), le panier peut présenter des déformations plus ou moins importantes du fait des températures élevées auxquelles il est exposé. En particulier, les parois verticales du panier se déforment et tendent ainsi à s'incurver, ce qui nuit alors à leur aptitude à être empilés, cet empilement étant nécessaire pour stocker et/ou disposer des paniers avant, pendant et après le traitement thermique.However, after a few successive passes in the heat treatment equipment (and sometimes after a single pass), the basket may have more or less significant deformations because of the high temperatures to which it is exposed. In particular, the vertical walls of the basket are deformed and thus tend to curl, which then affects their ability to be stacked, this stack being necessary to store and / or have baskets before, during and after the heat treatment.
Lorsque la déformation est trop importante, les paniers du type soudé doivent donc être remplacés intégralement, ce qui s'avère très coûteux du fait des coûts matière première des paniers fabriqués en acier réfractaire nickel-chrome et niobium.When the deformation is too large, the baskets of the welded type must be completely replaced, which is very expensive because of the raw material costs of the baskets made of nickel-chromium and niobium refractory steel.
Il a donc été proposé par l'art antérieur de réaliser des paniers de ce type dans une version démontable. Pour cela, les paniers sont constitués d'un fond et de quatre parois, l'assemblage étant obtenu à chaque angle par l'intermédiaire de pièces d'angle, tel qu'un axe ou un boulon.It has therefore been proposed by the prior art to make baskets of this type in a demountable version. For this, the baskets are constituted by a bottom and four walls, the assembly being obtained at each angle by means of corner pieces, such as an axis or a bolt.
De cette façon, il est possible de démonter les parois déformées, de tenter de les redresser, puis de les remonter.In this way, it is possible to disassemble the deformed walls, to try to straighten them, then to reassemble them.
De cette façon, les parois peuvent être redressées plusieurs fois, tant bien que mal, jusqu'au nécessaire remplacement de la paroi voire du panier.In this way, the walls can be straightened several times, somehow, until the necessary replacement of the wall or basket.
On peut ainsi prolonger la durée de vie des paniers. Toutefois, une limite à la durée de vie apparaît rapidement, dans la mesure où la pièce d'angle assurant l'assemblage à chaque angle du panier doit être introduite dans les douilles d'extrémité présentes à chaque extrémité des parois, l'assemblage et donc la mise en place de ces pièces d'angle impliquant la coaxialité des douilles de deux parois à relier par ladite pièce d'angle.This can extend the life of the baskets. However, a limit to the service life appears quickly, insofar as the corner piece ensuring assembly at each corner of the basket must be introduced into the end sleeves at each end of the walls, assembly and therefore the establishment of these corner pieces involving the coaxiality of the sleeves of two walls to be connected by said corner piece.
Bien entendu, au fur et à mesure des déformations et des opérations de redressement des parois, cette coaxialité est perdue et il n'est plus possible d'assembler les parois.Of course, as deformations and straightening operations of the walls, this coaxiality is lost and it is no longer possible to assemble the walls.
Cette perte de coaxialité peut aussi se traduire par une impossibilité de démontage du panier.This loss of coaxiality can also result in an impossibility of dismantling the basket.
Des solutions ont été proposées et décrites par les documents de brevet publiés sous les numéros
Toutefois, ces solutions ne permettent pas de réutiliser des paniers endommagés plus souvent, en limitant les effets de défaut de coaxialité des douilles de deux parois liées entre elles par la pièce d'angle.However, these solutions do not allow to reuse damaged baskets more often, limiting the effects of coaxiality defect sockets of two walls interconnected by the corner piece.
L'invention a notamment pour objectif de pallier cet inconvénient de l'art antérieur.The invention particularly aims to overcome this drawback of the prior art.
Plus précisément, l'invention a pour objectif de proposer un panier métallique pour le transport et/ou le stockage de pièces en particulier destiné à un traitement thermique, qui soit démontable/remontable en limitant les effets de défaut de coaxialité des douilles des deux parois liées entre elles par une pièce d'angle.More specifically, the invention aims to provide a metal basket for transport and / or storage of parts in particular intended for heat treatment, which can be dismantled / remounted by limiting the effects of coaxiality of the sockets of the two walls interconnected by a corner piece.
L'invention a également pour objectif de fournir un tel panier qui soit simple de conception et facile à fabriquer et à monter/démonter.The invention also aims to provide such a basket that is simple in design and easy to manufacture and assemble / disassemble.
Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints grâce à l'invention qui a pour objet un panier pour le transport et/ou le stockage de pièces, comprenant un fond et quatre parois de côté couplées chacune au fond et reliées deux à deux entre elles par l'intermédiaire d'une pièce d'angle insérée dans au moins une douille d'extrémité présente à chaque extrémité des parois, les douilles de deux parois à relier entre elles et au fond s'étendant l'une au-dessus de l'autre, la pièce d'angle étant susceptible de coopérer avec le fond, caractérisé en ce que les pièces d'angle présentent deux portions de coopération avec les douilles :
- une portion supérieure destinée à coopérer avec une douille dont la paroi interne est cylindrique et qui occupe une position supérieure de l'une des parois, la portion supérieure présentant au moins une zone dont le contour est au moins une fraction angulaire d'un tronc de cône s'élargissant de bas en haut en position dans ladite douille ;
- une portion inférieure destinée à coopérer avec une douille de l'autre paroi, cette douille étant en dessous de la douille en position supérieure, la portion inférieure présentant une excroissance circulaire destinée à être en contact avec une paroi interne de ladite douille en position inférieure.
- an upper portion intended to cooperate with a bushing whose internal wall is cylindrical and which occupies an upper position of one of the walls, the upper portion having at least one zone whose contour is at least an angular fraction of a trunk of cone widening from bottom to top in position in said socket;
- a lower portion intended to cooperate with a bushing of the other wall, this bushing being below the bushing in the upper position, the lower portion having a circular protrusion intended to be in contact with an inner wall of said bushing in the lower position.
Ainsi, grâce à l'invention, il est possible d'assembler deux parois adjacentes, c'est-à-dire à relier entre elles, tandis que leurs douilles respectives ne sont pas ou plus coaxiales.Thus, thanks to the invention, it is possible to assemble two adjacent walls, that is to say to connect together, while their respective sockets are not or more coaxial.
De plus, si des déformations importantes des parois du panier sont apparues pendant le traitement thermique des pièces qu'il contient et donc pendant le temps de traitement thermique pendant lequel le panier a été soumis à des températures très importantes, il est possible de retirer les pièces d'angle même si les déformations des parois ont conduit à un défaut de coaxialité des douilles des parois reliées entre elles.In addition, if significant deformations of the walls of the basket appeared during the heat treatment of the parts it contains and therefore during the heat treatment time during which the basket has been subjected to very high temperatures, it is possible to remove the corner pieces even if the deformations of the walls have led to a lack of coaxiality of the sleeves of the walls connected to each other.
Il en résulte qu'il est possible en toutes circonstances de démonter puis remonter les paniers conçus selon l'invention.It follows that it is possible in all circumstances to disassemble and reassemble the baskets designed according to the invention.
Il est donc possible de remettre en forme les parois des paniers selon l'invention en cas de nécessité, ceci de nombreuses fois.It is therefore possible to reshape the walls of the baskets according to the invention in case of necessity, this many times.
En tout état de cause, en rendant possible le démontage des paniers même en cas de défaut de coaxialité apparue pendant la durée du traitement thermique, ceci à un point tel que ce défaut de coaxialité pourrait empêcher le démontage en temps normal, on prolonge notablement la durée de vie des paniers, ce qui réduit les coûts de façon sensible pour l'entreprise qui les utilise.In any event, by making it possible to dismantle the baskets even in the event of a coaxiality defect that has occurred during the heat treatment period, to such an extent that this lack of coaxiality could prevent disassembly in normal time, the shelf life, which significantly reduces costs for the company that uses them.
Selon une solution préférentielle, les douilles et les portions de coopération de la pièce d'angle sont réparties en hauteur de façon à engendrer une cinématique d'assemblage en au moins deux phases successives :
- une phase de coopération de la portion inférieure avec la douille en dessous de la douille en position supérieure, visant à positionner la paroi correspondante par rapport à la pièce d'angle ;
- une deuxième phase de coopération de la portion supérieure avec la douille dont la paroi interne est cylindrique en vue de centrer dans cette douille la pièce d'angle.
- a cooperation phase of the lower portion with the bushing below the sleeve in the upper position, for positioning the corresponding wall relative to the corner piece;
- a second phase of cooperation of the upper portion with the sleeve whose inner wall is cylindrical in order to center in this socket the corner piece.
Selon une solution avantageuse, au moins l'une des deux parois à relier entre elles et au fond présente des premiers moyens d'engagement et en ce que le fond présente des deuxièmes moyens d'engagement destinés à coopérer avec les premiers moyens d'engagement de façon à permettre une mobilité de la paroi longitudinalement tandis qu'elle est maintenue orthogonalement au plan du fond.According to an advantageous solution, at least one of the two walls to be interconnected and at the bottom has first engagement means and in that the bottom has second engagement means for cooperating with the first engaging means. so as to allow mobility of the wall longitudinally while it is maintained orthogonally to the plane of the bottom.
De cette façon, l'utilisateur peut procéder à la mise en place des pièces d'angle et à l'assemblage des parois de façon simple et rapide.In this way, the user can proceed to the establishment of corner pieces and the assembly of walls in a simple and fast way.
En effet, au fur et à mesure de la mise en place de la pièce d'angle par rapport au fond du panier, en l'insérant au travers des douilles des deux parois à relier, l'une des parois (celle portant la douille en position inférieure) va tout d'abord être positionnée naturellement par rapport à l'axe de la pièce d'angle, puis en poursuivant la mise en place, la deuxième paroi va à son tour être positionnée par rapport à l'axe de la pièce d'angle. De cette façon, le défaut de coaxialité des douilles entre elles et/ou avec l'axe de la pièce d'angle est rattrapé sans effort particulier et sans technicité.Indeed, as and when setting the corner piece relative to the bottom of the basket, inserting through the sleeves of the two walls to be connected, one of the walls (the one carrying the socket in the lower position) will first be positioned naturally with respect to the axis of the corner piece, then continuing the implementation, the second wall will in turn be positioned relative to the axis of the corner piece. In this way, the lack of coaxiality of the sleeves between them and / or with the axis of the corner piece is caught without special effort and without technicality.
Selon un mode de réalisation avantageux, au moins l'une des deux parois à relier entre elles et au fond présente des premiers moyens d'engagement, le fond présentant des deuxièmes moyens d'engagement destinés à coopérer avec les premiers moyens d'engagement de façon à bien mettre une mobilité de la paroi longitudinalement tandis qu'elle est maintenue orthogonalement au plan du fond.According to an advantageous embodiment, at least one of the two walls to be interconnected and at the bottom has first engagement means, the bottom having second engaging means for cooperating with the first engaging means of engagement. way to put a mobility of the wall longitudinally while it is maintained orthogonally to the plane of the bottom.
Ainsi, on assure la liaison de chaque paroi dans sa longueur avec le fond du panier, assurant ainsi la bonne tenue mécanique et la rigidité du panier, tout en autorisant un débattement longitudinal autorisant le positionnement des douilles de la paroi correspondante par rapport à l'axe de la pièce d'angle lors de sa mise en place (ou de son retrait).Thus, it ensures the connection of each wall in its length with the bottom of the basket, thus ensuring the good mechanical strength and rigidity of the basket, while allowing a longitudinal movement allowing the positioning of the bushings of the corresponding wall relative to the axis of the corner piece when it is put in place (or removed).
Dans ce cas, les premiers moyens d'engagement prennent la forme d'au moins un crochet présentant une gorge s'étendant selon un axe longitudinal de la paroi, les deuxièmes moyens d'engagement prenant la forme d'au moins une languette destinée à venir se loger dans ladite gorge.In this case, the first engagement means take the form of at least one hook having a groove extending along a longitudinal axis of the wall, the second engagement means taking the form of at least one tongue intended to come and stay in the gorge.
Avantageusement, les premiers moyens d'engagement présentent au moins une paire de gorges s'étendant dans des directions opposées.Advantageously, the first engagement means have at least one pair of grooves extending in opposite directions.
Préférentiellement, les parois sont symétriques par rapport à leur axe médian vertical.Preferably, the walls are symmetrical with respect to their vertical median axis.
Ainsi, pour une dimension donnée, on limite le nombre de pièces, et en particulier de parois à fabriquer pour un panier déterminé. De plus, la symétrie des parois facilite le montage des paniers pour l'opérateur.Thus, for a given dimension, the number of parts, and in particular the walls to be manufactured for a given basket, is limited. In addition, the symmetry of the walls facilitates the mounting of the baskets for the operator.
Préférentiellement, chaque paroi présente, à chacune de ses extrémités, deux douilles ménageant entre elles un espace pour une douille d'une autre paroi à laquelle elle est destinée à être reliée.Preferably, each wall has, at each of its ends, two sockets leaving between them a space for a socket of another wall to which it is intended to be connected.
On améliore de cette façon la répartition des douilles aux extrémités des parois, augmentant ainsi la tenue mécanique et la résistance à la déformation des extrémités des parois.This improves the distribution of the bushings at the ends of the walls, thereby increasing the mechanical strength and the resistance to deformation of the ends of the walls.
De plus, la répartition des douilles est telle que les douilles d'une paroi sont disposées en alternance avec les douilles de l'autre paroi, ce qui contribue également à la bonne tenue mécanique et la résistance à la déformation des parois une fois assemblées.In addition, the distribution of the bushings is such that the bushings of one wall are arranged alternately with the bushings of the other wall, which also contributes to the good mechanical strength and the resistance to deformation of the walls once assembled.
Selon un mode de réalisation préférentiel, les pièces d'angle présentent une extrémité inférieure filetée, le fond présentant des angles pourvus chacun d'un taraudage destiné à coopérer avec une extrémité inférieure filetée d'une pièce d'angle.According to a preferred embodiment, the corner pieces have a threaded lower end, the bottom having angles each provided with a thread intended to cooperate with a threaded lower end of a corner piece.
L'installation d'une pièce d'angle s'opère donc par vissage des pièces d'angle dans le fond, ceci après avoir introduit la pièce d'angle dans les douilles des parois à relier entre elles. L'opération d'assemblage est ainsi particulièrement aisée à réaliser.The installation of a corner piece is therefore done by screwing the corner pieces in the bottom, this after having introduced the corner piece in the sleeves of the walls to be interconnected. The assembly operation is thus particularly easy to achieve.
Selon un mode de réalisation particulier, la douille de la paroi destinée à coopérer avec la portion inférieure de la pièce d'angle présente une forme oblongue s'étendant selon un axe longitudinal de ladite paroi.According to a particular embodiment, the sleeve of the wall intended to cooperate with the lower portion of the corner piece has an oblong shape extending along a longitudinal axis of said wall.
De cette façon, on augmente l'amplitude du débattement longitudinal de la paroi lors du positionnement des douilles de ladite paroi par rapport à l'axe de la pièce d'angle.In this way, the amplitude of the longitudinal deflection of the wall during the positioning of the sleeves of said wall with respect to the axis of the corner piece is increased.
Avantageusement, la portion supérieure présente deux portions diamétralement opposées dont le contour est une fraction angulaire d'un tronc de cône, les deux portions étant reliées par une paire de surface essentiellement plate.Advantageously, the upper portion has two diametrically opposed portions whose contour is an angular fraction of a truncated cone, the two portions being connected by a pair of substantially flat surface.
Ainsi, on constitue une tête sur la pièce d'angle dont la forme est particulièrement adaptée à la préhension de la pièce d'angle en vue d'exécuter l'installation de celle-ci par un mode opératoire de vissage dans le fond du panier tel que décrit précédemment.Thus, it constitutes a head on the corner piece whose shape is particularly suitable for gripping the corner piece to perform the installation thereof by a screwing procedure in the bottom of the basket as previously described.
Avantageusement, le fond des parois est réalisé en acier réfractaire.Advantageously, the bottom of the walls is made of refractory steel.
On obtient de cette façon un panier particulièrement adapté à contenir des pièces destinées à un traitement thermique.In this way, a basket is obtained which is particularly suitable for containing parts intended for heat treatment.

Dans le cas d'un panier prévu pour le transport et/ou le stockage de pièces destinées à un traitement thermique, le panier étant amené à être disposé avec les pièces qu'il contient dans l'équipement de traitement thermique, le fond et les parois du panier sont réalisés en un acier réfractaire comprenant un alliage de nickel-chrome et de niobium.In the case of a basket provided for the transport and / or storage of parts for heat treatment, the basket being made to be arranged with the parts it contains in the heat treatment equipment, the bottom and the Basket walls are made of a refractory steel comprising an alloy of nickel-chromium and niobium.
Selon le principe de l'invention, chaque pièce d'angle 3 présente deux portions 30, 31 de coopération décrites ci-après en référence aux
une portion supérieure 30 destinée à coopérer avec l'une des douilles des deux parois adjacentes à relier, en l'occurrence la douille 200 de la paroi telle qu'elle occupe une position supérieure ;- une portion inférieure 31, destinée à coopérer avec une douille 210 de l'autre paroi, cette douille s'étendant en dessous de la douille 200 qui coopère avec la
portion supérieure 30 de la pièce d'angle.
- an
upper portion 30 for cooperating with one of the sleeves of the two adjacent walls to connect, in this case thesleeve 200 of the wall as it occupies an upper position; - a
lower portion 31, intended to cooperate with abushing 210 of the other wall, this sleeve extending below thesleeve 200 which cooperates with theupper portion 30 of the corner piece.
La portion supérieure 30 de la pièce d'angle présente au moins une zone 300 dont le contour est au moins une fraction angulaire d'un tronc de cône, s'élargissant de bas en haut en position dans la douille correspondante.The
Telle qu'illustrée par les
La portion inférieure présente quant à elle une excroissance circulaire 310 destinée à être en contact avec une paroi interne 2100 de la douille 210 en position inférieure.The lower portion has a
Selon un mode de réalisation illustré par la
Ainsi, lors de la mise en place d'une pièce d'angle dans les douilles de deux parois adjacentes à relier entre elles et au fond du panier, on s'assure que la portion inférieure va entrer en coopération avec la douille correspondante avant que la portion supérieure n'entre en coopération avec la douille supérieure.Thus, during the establishment of a corner piece in the sleeves of two adjacent walls to be interconnected and at the bottom of the basket, it is ensured that the lower portion will enter into cooperation with the corresponding socket before the upper portion does not cooperate with the upper sleeve.
En d'autres termes, les douilles 200, 210 et les portions 30, 31 de coopération de la pièce d'angle sont réparties en hauteur de façon à engendrer une cinématique d'assemblage en deux phases successives :
- une phase de coopération de la portion inférieure 31 avec une douille (de l'autre paroi) positionnée en-dessous de la douille en position supérieure, cette première phase de coopération visant à positionner la paroi correspondante par rapport à la pièce d'angle 3, et en particulier par rapport à l'axe longitudinal A du corps 301 de la pièce d'angle ;
- une deuxième phase de coopération, au cours de laquelle,
la portion supérieure 30 coopère avec la douille en position supérieure, et plus précisément coopère avec la paroi interne cylindrique 2001 de cette douille en vue de centrer celle-ci dans la douille.
- a cooperation phase of the
lower portion 31 with a bushing (of the other wall) positioned below the bushing in the upper position, this first cooperation phase for positioning the corresponding wall with respect to thecorner piece 3 , and in particular with respect to the longitudinal axis A of the body 301 of the corner piece; - a second cooperation phase, during which the
upper portion 30 cooperates with the bushing in the upper position, and more specifically cooperates with the cylindricalinner wall 2001 of the sleeve to center it in the sleeve.
Il en résulte à l'issue de ces deux phases de coopération que les douilles des deux parois sont positionnées de façon prédéterminée et par rapport à l'axe longitudinal A du corps de la pièce d'angle.As a result of these two phases of cooperation, the bushes of the two walls are positioned in a predetermined manner and with respect to the longitudinal axis A of the body of the corner piece.
Selon le présent mode de réalisation, ces deux phases de coopération successives s'opèrent au cours d'une opération de vissage de la pièce d'angle dans le fond. En effet, tel que cela apparaît sur la
Par ailleurs, tel que cela apparaît sur la
Selon le présent mode de réalisation, ces premiers moyens d'engagement prennent la forme d'un crochet 2010 présentant une gorge 2011 s'étendant selon un axe X longitudinal de la paroi.According to the present embodiment, these first engagement means take the form of a
Les deuxièmes moyens d'engagement 202 prennent ici la forme d'une languette destinée à venir se loger dans la gorge correspondante du crochet.The second engagement means 202 here take the form of a tongue intended to be housed in the corresponding groove of the hook.
Avantageusement, la paroi présente deux crochets positionnés le long de la paroi de façon à coopérer avec deux languettes du fond au voisinage d'un angle. Dans ce cas, l'autre extrémité de la paroi, ainsi que l'autre extrémité du fond présente également des premiers moyens d'engagement, avec une paire de gorge s'étendant dans une direction opposée à celle des gorges à l'autre extrémité.Advantageously, the wall has two hooks positioned along the wall so as to cooperate with two tabs of the bottom in the vicinity of an angle. In this case, the other end of the wall, as well as the other end of the bottom also has first engagement means, with a pair of grooves extending in a direction opposite to that of the grooves at the other end .
Selon une autre caractéristique, les parois sont symétriques par rapport à leur axe médian vertical Y.According to another characteristic, the walls are symmetrical with respect to their vertical median axis Y.
Selon encore une autre caractéristique illustrée par les
