Description
PROCEDE ET DISPOSITIF D'OBTENTION EN CONTINU DE LINGOTS DE METAUX NON FERREUX A EMPILAGE AUTO-BLOQUANT A PARTIR D'UNE EBAUCHE ISSUE D'UNE MACHINE DE COULéE SUR ROUE A GORGE METHOD AND DEVICE FOR CONTINUOUSLY OBTAINING SELF-LOCKING NON-FERROUS METAL INGOTS FROM A BLANK FROM A THREAD WHEEL CASTING MACHINE
L'invention concerne un procédé et un dispositif d'obtention en continu à partir d'une ébauche de métal non ferreux issue d'une machine de coulée continue sur roue à gorge, de lingots de section constante et possédant à leurs extrémités des bossages se prêtant à la réalisation d'empilages auto-bloquants .The invention relates to a method and a device for continuously obtaining, from a non-ferrous metal blank from a continuous casting machine on a grooved wheel, ingots of constant cross section and having bosses at their ends. suitable for making self-blocking stacks.
L'homme de l'art sait que l'on peut réaliser, à partir de moules de forme convenable, des lingots présentant des parties en creux et/ou en relief sur une ou plusieurs de leurs faces et ce, afin d'empêcher tout déplacement relatif des lingots les uns par rapport aux autres lorsqu'ils sont assemblés sous forme de piles et d'en rendre ainsi le transport commode.Those skilled in the art know that ingots having hollow and / or raised portions on one or more of their faces can be produced from molds of suitable shape, in order to prevent any relative movement of the ingots with respect to each other when they are assembled in the form of stacks and thus making their transport convenient.
Cependant, cette technique recourt à des opérations discontinues de moulage, lingot par lingot, conduisant à des produits de structure et de composition assez hétérogènes, de poids variables et présentant une retassure de fin de solidification.However, this technique uses discontinuous molding operations, ingot by ingot, leading to products of fairly heterogeneous structure and composition, of variable weight and having a shrinkage at the end of solidification.
C'est pourquoi l'homme de l'art, pour parer à ces insuffisances, a cherchê à utiliser des appareils fonctionnant en continu, et notamment, dans le cas de lingots de section voisine ou inférieure au décimètre carré, des machines de coulée sur roue à gorge fermée par un ruban. L'ébauche continue de métal obtenue à la sortie de ces machines étant alors partagée en lingots distincts soit par sciage a la volée, soit, comme dans le brevet français 1 224 969, par matriçage suivi d'un cisaillage.This is why a person skilled in the art, in order to overcome these shortcomings, has sought to use devices operating continuously, and in particular, in the case of ingots with a section close to or less than a square decimetre, casting machines on grooved wheel closed by a ribbon. The continuous blank of metal obtained at the outlet of these machines is then divided into separate ingots either by sawing on the fly or, as in French patent 1 224 969, by stamping followed by shearing.
Cependant, chacun de ces procédés présente des inconvénients importants. Ainsi, dans le sciage, outre l'usure rapide des scies, une quantité appréciable "de- métal est dévalorisée sous forme de copeaux qu'il faut séparer de l'huile de coupe avant de les recycler. Dans le procédé par matriçage suivi d'un cisaillage, il est nécessaire de disposer d'une presse à matricer, et de plus, les lingots obtenus présentent sur leur longueur un renflement dû à l'effet d'écrasement de la matrice; d'où une section irré
gulière et un espacement plus ou moins grand entre eux lorsqu'ils sont alignés les uns à côté des autres et en conséquence une compacité relativement faible des piles qu'ils permettent de réaliser.However, each of these methods has significant drawbacks. Thus, in sawing, in addition to the rapid wear of the saws, an appreciable amount of metal is devalued in the form of chips which must be separated from the cutting oil before recycling them. In the die-forging process followed by '' a shearing, it is necessary to have a stamping press, and moreover, the ingots obtained have on their length a bulge due to the crushing effect of the matrix; whence an irreparable section gulière and a more or less large spacing between them when they are aligned next to each other and consequently a relatively low compactness of the stacks which they make it possible to produce.
Mais un inconvénient majeur de ces procédés, c'est que les lingots résultant de leur utilisation ne comportent aucun moyen susceptible de former un assemblage à bloc lorsqu'ils sont empilés.But a major drawback of these methods is that the ingots resulting from their use have no means capable of forming a block assembly when they are stacked.
C'est pourquoi la demanderesse a cherché et mis au point un procédé et un dispositif qui permettent la fabrication en continu, sans perte de métal, de lingots. de section constante, présentant les moyens nécessaires à l'édification de piles auto-bloquantes.This is why the applicant has sought and developed a method and a device which allow the continuous production, without loss of metal, of ingots. of constant section, presenting the means necessary for the construction of self-locking batteries.
Le procédé suivant l'invention consiste, de façon connue, à couler une ébauche sur une roue à gorge fermée temporairement par un ruban et à rendre périodiquement solidaire cette ébauche d'un dispositif chargé de la partager en lingots, mais il se caractérise en ce que l'ébauche est d'abord pincée de façon progressive sur ses faces latérales afin d'y former des empreintes et de développer au moins un bossage sur au moins une des autres faces, puis cisaillée au droit des empreintes.The process according to the invention consists, in a known manner, in casting a blank on a grooved wheel temporarily closed by a ribbon and in periodically making this blank integral with a device responsible for sharing it in ingots, but it is characterized in that that the blank is first pinched progressively on its lateral faces in order to form imprints there and to develop at least one boss on at least one of the other faces, then sheared in line with the imprints.
Ainsi, le procédé met en oeuvre, comme matière première, une ébauche issue d'une machine de coulée sur roue à gorge fermée temporairement par un ruban pour constituer un moule à parois mobiles.Thus, the method implements, as raw material, a blank from a casting machine on a grooved wheel temporarily closed by a ribbon to form a mold with movable walls.
L'ébauche sortant de la machine de coulée est d'abord ramenée dans une direction horizontale pour être enfilée entre les cylindres d'une dresseuse qui lui confère une rectitude convenable, puis elle s'engage dans le dispositif chargé de la partager en lingots.The preform leaving the casting machine is first brought in a horizontal direction to be threaded between the cylinders of a straightener which gives it a suitable straightness, then it engages in the device responsible for sharing it in ingots.
Ce dispositif est fixé par un chariot mobile qui comporte des moyens pour le rendre solidaire de l'ébauche. Ainsi, sous la poussée des cylindres de la dresseuse, l'ébauche entraîne avec aile le chariot, ce qui permet au dispositif de se déplacer de façon synchrone avec l'ëbauche et d'exercer son action de partage sur une section déterminée de cette dernière. Au cours de ce déplacement synchrone, l'ébauche est d'abord pincée de façon progressive sur ses faces latérales par le dis
positif de façon à y former des empreintes et à développer sur au moins une des autres faces, au moins un bossage.This device is fixed by a mobile carriage which includes means for making it integral with the blank. Thus, under the thrust of the straightening cylinders, the preform drives the carriage with the wing, which allows the device to move synchronously with the preform and to exercise its sharing action on a determined section of the latter. . During this synchronous movement, the blank is first of all progressively pinched on its lateral faces by the dis positive so as to form fingerprints there and to develop on at least one of the other faces, at least one boss.
Ces empreintes sont, de préférence, symétriques par rapport à un plan vertical passant par l'axe de l'ébauche et elles épousent plus ou moins la pente des faces latérales. La profondeur de ces empreintes peut varier suivant la nature du produit ou la forme de l'ébauche.These imprints are preferably symmetrical with respect to a vertical plane passing through the axis of the blank and they more or less follow the slope of the lateral faces. The depth of these indentations can vary depending on the nature of the product or the shape of the blank.
Les bossages qui se développent sur la face inférieure et/ou supérieure de l'ébauche se présentent sur une coupe au droit des empreintes comme deux mamelons séparés par un creux; ces mamelons dominent le plan de ces faces d'une hauteur qui peut être de l'ordre du 1/10 de la hauteur de l'ébauche et rejoignent cette face suivant une courbe convexe. Après pinçage, l'ébauche est coupée dans un plan perpendiculaire ou oblique à son axe, au droit des empreintes, c'est-à-dire de façon à partager les bossages par leur plan médian. Chaque lingot, ainsi obtenu, présente, dans le sens de la longueur, un profil en saillie à chacune de ses extrémités ce qui constitue le moyen de le rendre auto-bloquant dans un système d'empilage classique.The bosses which develop on the lower and / or upper face of the blank appear on a cut to the right of the imprints as two nipples separated by a hollow; these nipples dominate the plane of these faces with a height which can be of the order of 1/10 of the height of the blank and join this face according to a convex curve. After pinching, the blank is cut in a plane perpendicular or oblique to its axis, to the right of the imprints, that is to say so as to share the bosses by their median plane. Each ingot thus obtained has, in the longitudinal direction, a projecting profile at each of its ends which constitutes the means of making it self-locking in a conventional stacking system.
A la sortie du dispositif, chaque lingot est repris par une chaîne de traitement dans laquelle ori forme des nappes où un lingot sur deux peut être retourné afin d'amener ses faces latérales en contact étroit avec le lingot voisin; puis, on superpose les différentes nappes successivement dans le sens long et dans le sens travers de façon à constituer des piles.On leaving the device, each ingot is taken up by a processing chain in which ori forms sheets where one ingot out of two can be turned over in order to bring its lateral faces into close contact with the neighboring ingot; then, the different layers are superimposed successively in the long direction and in the cross direction so as to constitute stacks.
Dans ces piles, les bossages placés sur les deux côtés opposés de chaque nappe Bloquent à la fois les faces latérales de la nappe supérieure et de la nappe inférieure, ces dernières nappas bloquant elles-mêmes par leurs bossages les faces latérales de la nappe considérée. Les piles ainsi obtenues sont alors cerclées et peuvent être véhiculées sans aucun risque de déplacement relatif des lingots.In these stacks, the bosses placed on the two opposite sides of each ply Block both the lateral faces of the upper ply and the lower ply, these latter nappas themselves blocking by their bosses the lateral faces of the ply considered. The piles thus obtained are then encircled and can be transported without any risk of relative displacement of the ingots.
La présente invention concerne également un dispositif permettant de mettre en oeuvre le procédé décrit ci-dessus.
Ce dispositif est caractérisé en ce qu'il comporte, reliés au chariot mobile, deux mors placés en regard des faces latérales de l'é.bauche et destinés à former les empreintes et un couteau chargé de cisailler l'ébauche sur au moins une partie de sa section au droit des empreintes.The present invention also relates to a device making it possible to implement the method described above. This device is characterized in that it comprises, connected to the mobile carriage, two jaws placed opposite the lateral faces of the blank and intended to form the impressions and a knife responsible for shearing the blank on at least one part. of its section to the law of the prints.
Ces mors, de préférence identiques, sont de façon schématique constitués d'un prisme droit de section triangulaire surmonté d'un trièdre dont la base a la même section que le prisme. Ils sont en relation avec les montants latéraux du chariot par l'une de leurs faces tandis que les deux autres faces libres se coupent suivant une arête contenue dans un plan vertical perpendiculaire ou oblique à l'axe de déplacement de l'ébauche.These jaws, preferably identical, are schematically made up of a right prism of triangular section surmounted by a trihedron whose base has the same section as the prism. They are in relation to the lateral uprights of the carriage by one of their faces while the other two free faces intersect along an edge contained in a vertical plane perpendicular or oblique to the axis of movement of the blank.
En général, la hauteur de chaque mors est voisine de la hauteur de l'ëbauche de façon que l'empreinte se fasse du haut en bas des surfaces latérales. Associé à ces mors, se trouve un couteau fixé sur le chariot et dont le tranchant est placé au droit des arêtes des mors. Au repos, le tranchant du couteau est placé légèrement en retrait de la ligne de passe de l'ébauche.In general, the height of each jaw is close to the height of the blank so that the impression is made from top to bottom of the lateral surfaces. Associated with these jaws, there is a knife fixed on the carriage and whose cutting edge is placed in line with the edges of the jaws. At rest, the edge of the knife is placed slightly back from the roughing pass line.
Du point de vue fonctionnement, le mouvement du chariot, des mors et du couteau sont commandés automatiquement suivant une séquence comprenant les étapes suivantes : le chariot étant en position de repos, l'ébauche poussée par la dresseuse défile entre les éléments du dispositif. Au moment où la longueur de l'ébauche correspondant à celle des lingots qu'on veut obtenir est passée au droit des mors, le chariot est rendu solidaire de l ' ébauche par un moyen quelconque et se trouve entraîné à la même vitesse que l'ébauche. Ce mouvement de solidarisation entraîne la mise en route des mors qui viennent s'appliquer sur les faces latê—raies de l'ébauche pour s'enfoncer progressivement et marquer ces faces de leur empreinte. Dès que ces empreintes ont atteint la profondeur sou-haitée, les mors se retirent rapidement tandis que le couteau vient cisailler progressivement l'ébauche sur au moins une partie de sa section. Puis, le couteau se retire rapidement, le chariot est désolidarisé de l'ébauche, animé d'un mouvement rapide de translation de sens contraire à celui de l'ébauche sur une distance de l'ordre de celle de la longueur du lingot et la solidarisation s'établit à nouveau en vue d'une nouvelle coupe.
La présente invention sera mieux comprise à l'aide des dessins accompagnant la demande qui n'ont rien de limitatif et ont pour seul but de l'illustrer.From the operating point of view, the movement of the carriage, the jaws and the knife are automatically controlled according to a sequence comprising the following stages: the carriage being in the rest position, the blank pushed by the straightener runs between the elements of the device. At the moment when the length of the blank corresponding to that of the ingots which it is desired to obtain has passed in line with the jaws, the carriage is made integral with the blank by any means and is driven at the same speed as the draft. This movement of joining involves the starting of the jaws which come to be applied on the side-lines of the blank to gradually sink and mark these faces with their imprint. As soon as these imprints have reached the desired depth, the jaws quickly withdraw while the knife progressively shears the blank over at least part of its section. Then, the knife is quickly withdrawn, the carriage is detached from the blank, animated by a rapid movement of translation in the opposite direction to that of the blank over a distance of the order of that of the length of the ingot and the solidarity is established again for a new cut. The present invention will be better understood with the aid of the drawings accompanying the application which are in no way limiting and have the sole purpose of illustrating it.
