Description

Le charbon destiné à la cokéfaction est disposé dans des caissons d'enfournement où il est tassé au moyen d'une pilonneuse. Une pilonneuse comprend au moins un pilon qui comporte une forte semelle solidaire de l'extrémité inférieure d'une poutre en I. L'âme de ce I est équipée sur ses deux faces d'une garniture à fort coefficient de friction et coopère avec deux roues excentriques opposées entraînées en rotation. A chaque tour, les roues excentriques serrent entre elles l'âme du profilé et le propulsent verticalement vers le haut. Quand l'écartement entre les surfaces d'entraînement des roues augmente, par le jeu de l'excentricité, le pilon est libéré et chute librement sur la couche de charbon qui vient d'être déposée dans le caisson. Ces mouvements alternés ont lieu sur une course limitée par rapport à la longueur totale du profilé. Cette course est située dans une portion de la longueur du profilé qui se déplace le long de cette dernière en fonction du niveau du charbon dans le caisson.The coal intended for coking is placed in charging boxes where it is packed using a rammer. A rammer comprises at least one pestle which has a strong sole secured to the lower end of an I-beam. The core of this I is equipped on its two faces with a lining with a high coefficient of friction and cooperates with two opposite eccentric wheels driven in rotation. At each turn, the eccentric wheels clamp the web of the profile together and propel it vertically upwards. When the spacing between the wheel drive surfaces increases, by the play of eccentricity, the pestle is released and falls freely on the layer of carbon which has just been deposited in the box. These alternating movements take place over a limited stroke relative to the total length of the profile. This race is located in a portion of the length of the profile which moves along the latter depending on the level of carbon in the box.

Quand le caisson est plein, chaque pilon est remonté et est immobilisé dans la partie haute de la course pour permettre de dégager le caisson. Cet arrêt est obtenu par des mâchoires de serrage du profilé pour empêcher le pilon de retomber.When the box is full, each pestle is raised and is immobilized in the upper part of the stroke to allow the box to be released. This stop is obtained by clamping jaws of the profile to prevent the pestle from falling.

Pour atteindre un fonctionnement efficace de ce dispositif, il faut qu'il existe entre les roues excentriques et l'âme du profilé en I un coefficient de friction très élevé, ce qui impose de mettre en place des garnitures de friction sur les deux faces de l'âme du pilon. Ces garnitures sont des pièces d'usure qu'il faut régulièrement remplacer.To achieve efficient operation of this device, there must be a very high coefficient of friction between the eccentric wheels and the core of the I-profile, which means that friction linings must be fitted on both sides. the soul of the pestle. These seals are wearing parts which must be replaced regularly.

Pour mettre en place ou remplacer ces garnitures, on procède habituellement sur un banc où le profilé est posé de manière que son âme soit horizontale, ce qui oblige à retourner plusieurs fois le profilé pour travailler alternativement sur l'une et l'autre des faces de l'âme. Il n'est guère possible de procéder au retrait de la garniture usée puis à la pose d'une garniture neuve sur une face puis procéder de même sur l'autre face car les températures mises en jeu pour le collage et le décollage sont différentes. En effet, le décollage s'opérant à une température très supérieure au collage, il faudrait pour chaque face procéder à un refroidissement du pilon entre le retrait de la garniture usée et la pose de la garniture neuve, et limiter les échanges thermiques entre les deux faces lors du décollage de la garniture usée de la seconde face.To install or replace these linings, we usually proceed on a bench where the profile is placed so that its core is horizontal, which means that the profile has to be turned over several times to work alternately on either side. of soul. It is hardly possible to remove the worn lining and then to install a new lining on one side and then do the same on the other side because the temperatures involved for bonding and take-off are different. Indeed, the take-off taking place at a temperature much higher than bonding, it would be necessary for each face to cool the pestle between the removal of the worn lining and the fitting of the new lining, and to limit the heat exchanges between the two sides when taking off the worn lining from the second side.

Par ailleurs, même lorsqu'on procède alternativement au décollage sur l'une puis l'autre face puis au collage sur l'une et l'autre face, on soumet le pilon à des échauffements et des refroidissements unilatéraux qui engendrent des déformations qui nuisent à la qualité de l'adhérence obtenue et même au bon fonctionnement ultérieur du pilon. Il faut donc, dans chaque position, soumettre le profilé à une précontrainte s'opposant à ces déformations.Furthermore, even when taking off alternately on one side then the other side and then bonding on both sides, the pestle is subjected to unilateral heating and cooling which generate deformations which harm to the quality of the adhesion obtained and even to the correct subsequent operation of the pestle. It is therefore necessary, in each position, to subject the profile to a prestress opposing these deformations.

On comprend que la méthode utilisée jusqu'à présent soit de mise en oeuvre assez compliquée et assez longue.It is understood that the method used until now is quite complicated and quite long to implement.

La présente invention entend proposer des moyens pour simplifier la pose ou le remplacement de ces garnitures de friction.The present invention intends to propose means for simplifying the installation or replacement of these friction linings.

A cet effet, elle a donc pour objet une machine pour procéder au garnissage et au dégarnissage des deux faces opposées de l'âme d'un profilé, l'une et l'autre des opérations impliquant un apport de calories pour agir sur le liant interposé entre le profilé et ses garnitures.To this end, it therefore relates to a machine for filling and stripping the two opposite faces of the core of a profile, both of the operations involving a supply of calories to act on the binder interposed between the profile and its fittings.

Selon l'invention, cette machine comporte, sur un bâti, un support du profilé dans une position où l'âme est verticale, ce support étant disposé entre deux mâchoires horizontales de longueurs au moins égales à celle des garnitures à mettre en place sur le profilé, ces mâchoires étant attelées à des organes moteurs pour les rapprocher ou les écarter l'une de l'autre dans un mouvement perpendiculaire à l'âme du profilé et pour les maintenir en position serrée sur l'âme avec une force déterminée, les mâchoires étant pourvues de moyens de chauffage et de refroidissement de leur surface en regard l'une de l'autre.According to the invention, this machine comprises, on a frame, a support for the profile in a position where the core is vertical, this support being disposed between two horizontal jaws of lengths at least equal to that of the linings to be placed on the profiled, these jaws being coupled to motor members to bring them closer or separate them from one another in a movement perpendicular to the core of the profile and to keep them in a tight position on the core with a determined force, the jaws being provided with means for heating and cooling their surface facing one another.

Dans un mode de réalisation de l'invention, l'une des mâchoires est fixe en coulissement par rapport au bâti, le support du profilé étant monté mobile en coulissement par rapport au bâti de manière à pouvoir être rapproché et écarté de la mâchoire fixe lors du mouvement de l'autre mâchoire. Cette disposition permet de disposer les organes moteurs d'un seul côté de la machine ce qui en simplifie la mise en oeuvre et l'entretien.In one embodiment of the invention, one of the jaws is fixed in sliding with respect to the frame, the support of the profile being mounted movable in sliding with respect to the frame so as to be able to be moved towards and away from the fixed jaw during movement of the other jaw. This arrangement makes it possible to have the drive members on one side of the machine, which simplifies implementation and maintenance.

De manière avantageuse, afin de pouvoir facilement procéder au retrait des garnitures usées et à l'encollage du profilé pour la pose de garnitures neuves, la machine comporte un second support pour le profilé constitué par au moins deux bras escamotables entre une première position où ils sont sous le premier support et une seconde position où ils sont au-dessus de ce premier support, chaque bras comportant des moyens de bridage du profilé montés tournants dans ce bras autour d'un axe parallèle à celui du profilé.Advantageously, in order to be able to easily remove the worn linings and to glue the profile for the installation of new linings, the machine comprises a second support for the profile constituted by at least two arms retractable between a first position where they are under the first support and a second position where they are above this first support, each arm comprising means for clamping the profile rotatably mounted in this arm around an axis parallel to that of the profile.

De même, pour faciliter la mise en place des garnitures neuves sur les mâchoires avant de les transférer sur l'âme encollée, les mâchoires sont montées pivotantes par rapport au bâti entre une première position où leur face active est verticale en regard l'une de l'autre et une seconde position où leur face active est horizontale tournée vers le haut.Likewise, to facilitate the fitting of new linings on the jaws before transferring them to the glued core, the jaws are pivotally mounted relative to the frame between a first position where their active face is vertical opposite one of the other and a second position where their active face is horizontal facing upwards.

Enfin, dans un mode de réalisation préféré de l'invention, la mâchoire mobile est montée sur un chariot coulissant sur le bâti perpendiculairement au premier support, les organes moteurs étant constitués par des vérins attelés entre le bâti et ce support coulissant, les moyens d'entraînement en basculement des mâchoires étant constitués, pour la mâchoire mobile par une roue d'entraînement montée tournante sur le chariot coopérant avec une crémaillère fixe solidaire du bâti lorsque le chariot est déplacé dans cette zone du bâti, et pour la mâchoire fixe par un levier extensible élastiquement attelé entre la première et la seconde mâchoire. En outre, en rendant le second support solidaire de la première mâchoire, la simple commande du serrage ou de desserrage des mâchoires permet d'accomplir tous les mouvements et ce, de manière synchronisée.Finally, in a preferred embodiment of the invention, the movable jaw is mounted on a carriage sliding on the frame perpendicular to the first support, the drive members being constituted by jacks coupled between the frame and this sliding support, the means for tilting jaws being formed, for the movable jaw by a drive wheel rotatably mounted on the carriage cooperating with a fixed rack integral with the frame when the carriage is moved in this area of the frame, and for the fixed jaw by an elastically extendable lever coupled between the first and second jaws. In addition, by making the second support integral with the first jaw, the simple control of the clamping or loosening of the jaws makes it possible to accomplish all the movements and this, in synchronized manner.

L'invention sera mieux comprise au cours de la description d'un mode de réalisation donné ci-après à titre indicatif qui permettra d'en dégager les avantages et les caractéristiques secondaires.The invention will be better understood during the description of an embodiment given below by way of indication which will make it possible to identify the advantages and the secondary characteristics thereof.

Il sera fait référence aux dessins annexés dans lesquels:

  • la figure 2 est une coupe schématique transversale de la machine selon l'invention faisant apparaître les organes de liaison des mâchoires basculantes,
  • la figure 3 est une coupe schématique transversale de la machine selon l'invention représentant le support auxiliaire du profilé à garnir/dégarnir.
Reference will be made to the appended drawings in which:
  • FIG. 1 is a partial view of the elements illustrating the essential functions performed by the machine according to the invention,
  • FIG. 2 is a schematic transverse section of the machine according to the invention showing the connecting members of the tilting jaws,
  • Figure 3 is a schematic cross section of the machine according to the invention showing the auxiliary support of the profile to be trimmed / stripped.

Il faut comprendre la figure 1 comme un schéma simplifié des moyens mis en oeuvre dans la machine selon l'invention. Le profilé 1 à traiter est ici représenté reposant sur un support 2 horizontal de manière à présenter son âme 1a verticalement. Le support 2 est disposé entre deux mâchoires 3 et 4 qui s'étendent parallèlement entre elles et au support 2. La longueur des mâchoires est au moins égale à celle de la garniture à mettre en place sur le profilé (de l'ordre de quelques mètres).Figure 1 should be understood as a simplified diagram of the means used in the machine according to the invention. The section 1 to be treated is here shown resting on a horizontal support 2 so as to have its core 1 has vertically. The support 2 is arranged between two jaws 3 and 4 which extend parallel to each other and to the support 2. The length of the jaws is at least equal to that of the lining to be placed on the profile (of the order of a few meters).

Le support 2 comprend une armature 5 de soutien de galets ou rouleaux 6 sur lesquels le profilé 1 peut être glissé depuis une extrémité longitudinale de la machine. Ce support peut être en plusieurs tronçons 2a, 2b indépendants les uns des autres séparés par des espaces tels que 7 pour le passage vertical d'un support secondaire 8, normalement escamoté sous le profilé 1.The support 2 comprises an armature 5 for supporting rollers or rollers 6 on which the profile 1 can be slid from a longitudinal end of the machine. This support can be in several sections 2 a , 2 b independent of each other separated by spaces such as 7 for the vertical passage of a secondary support 8, normally retracted under the profile 1.

Le support 2 et les mâchoires 3 et 4 sont supportés par un bâti non représenté sur la figure 1. Des moyens d'entraînement des mâchoires sont attelés entre ces dernières et le bâti pour les éloigner ou les rapprocher l'une de l'autre afin de serrer entre elles l'âme 1a du support et de supprimer ce serrage. On peut prévoir que le support 2 soit fixe par rapport au bâti et que les mâchoires soient mobiles de part et d'autre de ce support fixe. Cependant, afin de diminuer le nombre d'actionneurs, on préfère rendre la mâchoire 3 fixe par rapport au bâti et n'agir que sur la mâchoire 4 mobile dans le sens des flèches A de la figure 1. Dans ce cas, le support 2 est également mobile pour être entraîné en direction de la mâchoire 3 par la mâchoire 4. Les moyens de liaison du support 2 par la mâchoire 4 sont symbolisés par les liaisons élastiques 9 et 10 disposées entre le support et chacune des mâchoires qui se compriment lors du rapprochement des mâchoires en déplaçant le support 2 en direction de la mâchoire 3 d'une valeur sensiblement égale à la demi-course de la mâchoire 4, et qui se détendent lors de l'éloignement des mâchoires pour éloigner, de cette même valeur, le support 2 de la mâchoire 3.The support 2 and the jaws 3 and 4 are supported by a frame not shown in FIG. 1. Means for driving the jaws are coupled between the latter and the frame to move them away or bring them closer to each other so to tighten between them the core 1 a of the support and to remove this tightening. It can be provided that the support 2 is fixed relative to the frame and that the jaws are movable on either side of this fixed support. However, in order to reduce the number of actuators, it is preferable to make the jaw 3 fixed relative to the frame and to act only on the movable jaw 4 in the direction of the arrows A in FIG. 1. In this case, the support 2 is also movable to be driven towards the jaw 3 by the jaw 4. The means of connecting the support 2 by the jaw 4 are symbolized by the elastic connections 9 and 10 disposed between the support and each of the jaws which compress during approximation of the jaws by moving the support 2 in the direction of the jaw 3 by a value substantially equal to the half-stroke of the jaw 4, and which relax during the distance of the jaws to move, from this same value, the jaw support 2 3.

Chaque mâchoire 3, 4 possède une face active 3a, 4a qui forme une semelle de support de la garniture à appliquer sur le profilé, cette semelle pouvant être chauffée et refroidie par des moyens caloporteurs situés en 3b, 4b dans chaque mâchoire au droit des semelles 3a, 4a (circuit de circulation d'eau ou de vapeur, résistance électrique, circuit de circulation d'air....).Each jaw 3, 4 has an active face 3 a , 4 a which forms a support sole for the lining to be applied to the profile, this sole being able to be heated and cooled by heat transfer means located in 3 b , 4 b in each jaw in line with the soles 3 a , 4 a (water or steam circulation circuit, resistance electric, air circulation circuit ....).

De manière avantageuse, chaque mâchoire 3 et 4 est en deux parties articulées autour d'un axe 11, 12 parallèle à la direction du profilé 1 sur son support. Pour la mâchoire 3, les deux parties comportent une portion du bâti fixe 13a et la mâchoire proprement dite 13b. Pour la mâchoire 4, la première partie 14a constitue un chariot coulissant sur le bâti sur lequel agissent les organes d'entraînement, la seconde partie 14b constituant la partie active de l'étau. Ces articulations permettent de placer horizontalement les surfaces 3a et 4a afin de faciliter la mise en place de la garniture à appliquer sur le profilé.Advantageously, each jaw 3 and 4 is in two parts articulated around an axis 11, 12 parallel to the direction of the profile 1 on its support. For the jaw 3, the two parts comprise a portion of the fixed frame 13 a and the jaw proper 13 b . For the jaw 4, the first part 14 a constitutes a carriage sliding on the frame on which the drive members act, the second part 14 b constituting the active part of the vice. These joints make it possible to place the surfaces 3 a and 4 a horizontally in order to facilitate the positioning of the lining to be applied to the profile.

Enfin, le support secondaire 8 comporte au moins deux fourches (une seule 15 est représentée sur la figure) qui peuvent être manoeuvrées verticalement selon les flèches B pour prendre en charge le profilé 1 et le soulever du support 2. Ces fourches 15 possèdent chacune une portion centrale 16 comportant des moyens de bridage du profilé et montée tournante autour de l'axe longitudinal du profilé dans un support extérieur qui permet, une fois le profilé soulevé, de placer son âme 1a horizontalement dans l'une et l'autre des deux positions, afin d'avoir aisément accès à chacune des faces de cette âme pour, par exemple, procéder au retrait de la garniture usagée qui aurait subi préalablement un traitement thermique de décollage (au moyen des mâchoires 3 et 4).Finally, the secondary support 8 comprises at least two forks (only one is shown in the figure) which can be maneuvered vertically according to the arrows B to take over the profile 1 and lift it from the support 2. These forks 15 each have a central portion 16 having the profile of the clamp means and rotatably mounted about the longitudinal axis of the profile in an outer support which allows, once the raised profile, placing its core 1 has horizontally in one and the other of two positions, in order to have easy access to each of the faces of this core in order, for example, to remove the used lining which would have previously undergone a thermal take-off treatment (by means of the jaws 3 and 4).

Les figures 2 et 3 illustrent une réalisation préférée de la machine présentée schématiquement par la figure 1.Figures 2 and 3 illustrate a preferred embodiment of the machine shown schematically in Figure 1.

On retrouve sur ces figures la plupart des éléments déjà décrits avec les mêmes références.Most of the elements already described with the same references are found in these figures.

La figure 2 a pour objet d'illustrer les moyens permettant la manoeuvre synchronisée des mâchoires 3 et 4 tant dans leur mouvement de rapprochement/éloignement que dans leur mouvement autour de leur articulation.Figure 2 is intended to illustrate the means for the synchronized operation of the jaws 3 and 4 both in their movement of movement / distance as in their movement around their articulation.

La référence 20 est attachée au bâti de la machine dont une partie constitue le support fixe 13a de la mâchoire 3 sur laquelle elle est articulée. Le socle (ou chariot) coulissant 14a de la mâchoire 4 est attelé à la tige d'un vérin 21 (en réalité la machine comporte plusieurs vérins régulièrement répartis le long de la mâchoire 4). La portion 14b de la mâchoire 4 est solidaire d'une roue dentée 22 qui tourne avec elle autour de l'axe 12. Cette roue dentée 22 coopère avec une crémaillère 23 portée par le bâti au cours de la phase finale de rétraction du vérin 21 ou de sa première phase d'extension. On comprend qu'ainsi, en fin de course d'ouverture des mâchoires ou de début de leur course de fermeture, on provoque le pivotement de la partie 14b de la mâchoire 4 autour de l'axe 12. La mâchoire 4 passe donc de sa position face 4a dirigée vers le profilé 1 (figure 2) à sa position face 4a horizontale (figure 3).The reference 20 is attached to the frame of the machine part of which constitutes the fixed support 13 a of the jaw 3 on which it is articulated. The base (or carriage) 14 a sliding of the jaw 4 is coupled to the rod of a cylinder 21 (in fact the machine comprises a plurality of jacks regularly distributed along the jaw 4). The portion 14b of the jaw 4 is integral with a toothed wheel 22 which rotates with it around the axis 12. This toothed wheel 22 cooperates with a rack 23 carried by the frame during the final phase of retraction of the jack 21 or its first extension phase. We understand that thus, at the end of the jaw opening stroke or at the start of their closing stroke, the part 14b of the jaw 4 is pivoted around the axis 12. The jaw 4 therefore passes from its position 4 is directed to the section 1 (Figure 2) to its position 4 a horizontal (Figure 3).

L'entraînement en pivotement synchronisé de la mâchoire 3 est assuré par une liaison des mâchoires 3 et 4 au moyen d'un levier 24 élastiquement télescopique (en réalité deux leviers 24 relient les mâchoires 3 et 4 à chacune de leurs extrémités, au delà des extrémités du support 2). Chacune des mâchoires 3 et 4 possède un bras 25, 26. Le bras 25 est articulé au levier 24 autour d'un axe 27 porté par un coulisseau 28 glissant le long du levier 24 et soumis aux effets antagonistes de deux ressorts 29 et 30. Le bras 26 est quant à lui articulé à l'extrémité du levier 24 autour d'un axe 31. Les axes 11, 12, 27 et 31 forment les sommets d'un quadrilatère déformable. Ainsi, à partir de la position représentée en figure 2, le rapprochement des mâchoires va pousser l'axe 27 vers la gauche de la figure, donc ramener la mâchoire 3 en position horizontale, en butée sur le bâti. La poursuite de ce rapprochement reste possible grâce au coulisseau 28 qui permet la translation du levier 24 par rapport au bras 25.The synchronized pivoting drive of the jaw 3 is ensured by a connection of the jaws 3 and 4 by means of an elastically telescopic lever 24 (in reality two levers 24 connect the jaws 3 and 4 at each of their ends, beyond the support ends 2). Each of the jaws 3 and 4 has an arm 25, 26. The arm 25 is articulated to the lever 24 about an axis 27 carried by a slide 28 sliding along the lever 24 and subjected to the antagonistic effects of two springs 29 and 30. The arm 26 is in turn articulated at the end of the lever 24 about an axis 31. The axes 11, 12, 27 and 31 form the vertices of a deformable quadrilateral. Thus, from the position shown in Figure 2, the approximation of the jaws will push the axis 27 to the left of the figure, so bring the jaw 3 in a horizontal position, in abutment on the frame. The continuation of this approximation remains possible thanks to the slide 28 which allows the translation of the lever 24 relative to the arm 25.

L'ouverture des mâchoires (par action du vérin 21) comporte d'abord une phase de coulissement du levier 24 par rapport au coulisseau 28 maintenu fixe sous l'effet du ressort 30. Lorsque le ressort 30 est équilibré par le ressort 29, c'est à dire sensiblement à l'instant où la roue 22 attaque la crémaillère 23, le début de la rotation du bras 26 (combinée à son coulissement vers la droite de la figure) provoque l'entraînement en rotation de la mâchoire 3 autour de l'axe 11, jusqu'à la position représentée en figure 3. Le ressort 29 permet de rendre plus souple l'entraînement du bras 26 par le levier 24 et d'encaisser les efforts de fin de course. La rotation inverse est obtenue par l'extension du vérin 21.The opening of the jaws (by action of the jack 21) first comprises a phase of sliding of the lever 24 relative to the slide 28 kept fixed under the effect of the spring 30. When the spring 30 is balanced by the spring 29, c '' is to say substantially at the moment when the wheel 22 attacks the rack 23, the beginning of the rotation of the arm 26 (combined with its sliding to the right of the figure) causes the jaw 3 to rotate around the axis 11, to the position shown in FIG. 3. The spring 29 makes it possible to make the drive of the arm 26 more flexible by the lever 24 and to absorb the end-of-travel forces. Reverse rotation is obtained by extending the jack 21.

Sur cette figure on a également représenté en 9 et 10 le dispositif de liaison élastique du support 2 aux mâchoires 3 et 4 qui permet d'entraîner le support 2 en direction de la mâchoire 3 lors de la fermeture de l'étau et de l'écarter de cette mâchoire 3 lors de l'ouverture.This figure also shows in 9 and 10 the elastic connection device of the support 2 to the jaws 3 and 4 which makes it possible to drive the support 2 in the direction of the jaw 3 during the closing of the vice and the move away from this jaw 3 when opening.

La figure 3 illustre une réalisation préférée du support auxiliaire 8. Dans ce cas, le support 8 est solidaire de la mâchoire pivotante 4 de sorte que le pivotement de cette dernière entraîne l'élévation du support 8 qui, dans son mouvement, prend en charge le profilé 1 pour le placer dans la position représentée en figure 3.FIG. 3 illustrates a preferred embodiment of the auxiliary support 8. In this case, the support 8 is integral with the pivoting jaw 4 so that the pivoting of the latter causes the support 8 to rise, which, in its movement, takes charge profile 1 to place it in the position shown in Figure 3.

Dans cette position, il est aisé d'accéder aux faces de l'âme 1a et, par le moyen de la portion centrale 16 pivotant dans la fourche 15, de retourner le profilé selon les flèches C. Bien entendu, la machine comprendra un support 8 en au moins deux parties distantes l'une de l'autre le long de l'axe longitudinal du profilé.In this position, it is easy to access the faces of the core 1 a and, by means of the central portion 16 pivoting in the fork 15, to return the profile according to the arrows C. Of course, the machine will include a support 8 in at least two parts distant from each other along the longitudinal axis of the profile.

Le fonctionnement de cette machine se déroule de la façon suivante:The operation of this machine is as follows:

Le profilé 1 à regarnir est placé sur le support 2, avec sur chaque face de l'âme 1a sa garniture usagée. Le retrait de celle-ci demande un chauffage préalable à une température de l'ordre de 120 à 150°C. Ce chauffage est obtenu en resserrant les mâchoires 3 et 4 sur le profilé et en chauffant leur semelle 3a, 4a.The profile 1 to be relined is placed on the support 2, with on each face of the core 1 has its used lining. Removing it requires prior heating at a temperature of the order of 120 to 150 ° C. This heating is obtained by tightening the jaws 3 and 4 on the profile and by heating their sole 3 a , 4 a .

L'ouverture complète des mâchoires place la machine dans la configuration représentée en figure 3. Il est alors possible de retirer les garnitures usagées au moyen d'outils appropriés (socs ou racloirs) et d'un mouvement relatif créé entre le profilé et ces outils.The complete opening of the jaws places the machine in the configuration shown in Figure 3. It is then possible to remove the used linings using appropriate tools (plowshares or scrapers) and a relative movement created between the profile and these tools .

Il est ensuite aisé de préparer la pose des garnitures neuves. On peut encoller les deux faces de l'âme 1a du profilé en retournant aisément celui-ci. On pose les garnitures neuves sur les semelles des mâchoires 3 et 4 qui sont horizontales et on les encolle également. On ferme ensuite la machine. Le profilé est déposé sur le support 2, les mâchoires se resserrent et on maintient la pression en chauffant les semelles à une température et pendant une durée (de l'ordre de l'heure) dépendant de la nature de la colle employée. La polymérisation de la colle étant réalisée, on peut procéder au refroidissement accéléré de l'ensemble en faisant circuler un fluide de refroidissement dans les mâchoires. Ainsi si la température de polymérisation est de l'ordre de 80°C, on peut atteindre la température ambiante au bout d'un quart d'heure environ.It is then easy to prepare the installation of the new linings. We can glue the two sides of the core 1 a of the profile by easily turning it over. The new linings are placed on the soles of the jaws 3 and 4 which are horizontal and they are also glued. The machine is then closed. The profile is deposited on the support 2, the jaws tighten and the pressure is maintained by heating the soles to a temperature and for a duration (of the order of an hour) depending on the nature of the adhesive used. Once the adhesive has polymerized, the assembly can be accelerated to cool by circulating a cooling fluid in the jaws. Thus, if the polymerization temperature is of the order of 80 ° C., it is possible to reach room temperature after about a quarter of an hour.

La machine selon l'invention permet de simplifier considérablement les opérations d'entretien des pilonneuses et d'améliorer la qualité du garnissage.The machine according to the invention makes it possible to considerably simplify the maintenance operations of the rammers and to improve the quality of the lining.
