Description

La présente invention concerne un dispositif d'entaillage et son procédé d'utilisation dans une chaîne de traitement en continu, une chaîne de décapage ou un laminoir à froid pour le laminage de bandes métalliques. Plus particulièrement elle concerne un dispositif d'entaillage rotatif servant à découper d'une manière uniforme et continue un élément le long d'arêtes longitudinales opposées d'une bande, au voisinage d'un joint soudé existant entre deux bandes réunies.The present invention relates to a notching device and its method of use in a continuous processing chain, a pickling chain or a cold rolling mill for the rolling of metal strips. More particularly, it relates to a rotary notching device used for uniformly and continuously cutting an element along opposite longitudinal edges of a strip, in the vicinity of a welded joint existing between two joined strips.

L'entaillage de deux bandes assemblées au niveau de leur joint soudé en cours de déplacement dans une chaîne de traitement continu, est d'une pratique usuelle et est mis en oeuvre de manière à réaliser 1? finition des arêtes de la zone soudée afin d'éliminer ou de réduire le risque que des parties rugueuses accrochent et endommagent l'équipement que la bande traverse ultérieurement et également afin d'éliminer des angles saillants lorsque l'on doit souder des bandes de différentes largeurs.The tapping of two strips assembled at their welded joint during movement in a continuous processing chain, is a usual practice and is implemented so as to achieve 1? finishing the edges of the welded area in order to eliminate or reduce the risk of rough parts catching and damaging the equipment that the strip subsequently crosses and also in order to eliminate salient angles when it is necessary to weld strips of different widths.

Les appareils classiques servant à former une encoche rentrante au niveau des bords longitudinaux d'un joint soudé entre deux bandes horizontales réunies utilisent ce que l'on désigne habituellement sous le terme de dispositif d'entaillage "à ailettes", un tel dispositif d'entaillage "à ailettes" étant constitué de deux unités d'entaillage des bords, écartées transversalement l'une de l'autre et entre lesquelles circule la bande. Chaque unité d'entaillage est disposée à distance de la bande lorsque cette dernière circule dans la chaîne, et pour l'opération d'entaillage, la bande est complètement arrêtée et les unités d'entaillage sont rapprochées l'une de l'autre vers les arêtes longitudinales de la bande. Chaque unité d'entaillage porte une tête actionnée par un vérin et portant un mécanisme de poinçonnage qui réalise une découpe de configuration prédéterminée au niveau du joint soudé.Conventional devices used to form a re-entrant notch at the longitudinal edges of a welded joint between two horizontal strips joined together use what is usually designated by the term "notching device", such a device "fins" notching consisting of two edge notching units, spaced transversely from each other and between which the strip circulates. Each tapping unit is placed at a distance from the strip when the latter is circulating in the chain, and for the tapping operation, the strip is completely stopped and the tapping units are brought towards each other towards the longitudinal edges of the strip. Each notching unit carries a head actuated by a jack and carrying a punching mechanism which performs a cutout of predetermined configuration at the welded joint.

Pour cette opération, les unités d'entaillage de ces appareils classiques sont déplacées vers les arêtes de la bande.A la sortie du poste de soudage, la bande est arrêtée lorsque le joint soudé de la bande assemblée se déplace parallèlement aux deux unités d'entaillage. La tête portant le poinçon est rapprochée verticalement de la surface horizontale de la bande pour le processus d'entaillage, à la suite de quoi chaque unité est écartée de la bande pour permettre la poursuite du déplacement de la bande dans la chaîne. On notera que le fait d'exiger un arrêt de la bande entraîne un temps d'arrêt considérable et une baisse de production de la chaîne.For this operation, the notching units of these conventional devices are moved towards the edges of the strip. At the exit of the welding station, the strip is stopped when the welded joint of the assembled strip moves parallel to the two notching. The head carrying the punch is brought vertically close to the horizontal surface of the strip for the notching process, after which each unit is moved away from the strip to allow the further movement of the strip in the chain. It will be noted that the fact of requiring a stop of the strip leads to a considerable stop time and a drop in production of the chain.

C'est pourquoi un but de la présente invention est de fournir un appareil et un procédé pour découper une zone le long d'une arête longitudinale d'un produit en déplacement, sans interrompre son déplacement, l'entaille étant réalisée à la volée dans le produit, ce qui entraîne un accroissement de la production de la chaîne.This is why an object of the present invention is to provide an apparatus and a method for cutting an area along a longitudinal edge of a product in movement, without interrupting its movement, the notch being produced on the fly in the product, which leads to increased production in the chain.

Un autre but de la présente invention est de fournir un appareil utilisé dans une chaîne de traitement continu de bandes métalliques disposée en aval d'un appareil de soudage, en vue de réduire le temps de soudage total pour deux bandes et la durée d'entaillage nécessaire avec les appareils d'entaillage actuels, ce qui requiert une installation d'accumulation et de stockage moins onéreuse, en particulier dans le cas de l'utilisation d'une soudeuse à arc.Another object of the present invention is to provide an apparatus used in a continuous processing chain for metal strips arranged downstream of a welding device, with a view to reducing the total welding time for two strips and the duration of notching. necessary with current tapping devices, which requires a cheaper accumulation and storage installation, in particular in the case of the use of an arc welder.

Plus particulièrement un but de la présente invention est de fournir un dispositif d'entaillage rotatif de bandes dans une chaîne de traitement continu de bandes, permettant d'accélérer la bande dans la chaîne après le soudage de deux bandes assemblées en réalisant, dans le joint soudé se rapprochant du dispositif d'entaillage rotatif, le découpage d'une courbe continue et régulière le long des arêtes longitudinales du joint, celles-ci n'ayant pas dû être soudées auparavant.More particularly, an object of the present invention is to provide a device for rotary notching of strips in a continuous strip processing chain, making it possible to accelerate the strip in the chain after the welding of two assembled strips by making, in the joint welded approaching the rotary notching device, the cutting of a continuous and regular curve along the longitudinal edges of the joint, these should not have been welded before.

Un autre but de la présente invention est de fournir un appareil pour cisailler et éliminer une partie prédéterminée le long d'au moins une première arête longitudinale d'un matériau métallique en déplacement, comprenant des moyens en forme de tambours situés le long de cette première arête longitudinale et comportant au moins deux tambours rotatifs distants l'un de l'autre et coopérant entre eux et dont chacun possède un axe de rotation et entre lesquels circule ledit bord dudit matériau, des moyens pour supporter, en console, lesdits tambours transversalement par rapport audit matériau de manière que leurs axes soient alignés l'un sur l'autre dans un plan vertical, et pour maintenir lesdits tambours dans une position de cisaillement et de non cisaillement par rapport audit matériau, lesdits tambours possédant des faces courbes et planes coopérant respectivement entre elles, des moyens en forme de couteaux courbes montés sur lesdites faces courbes desdits tambours et constitués et agencés de manière à réaliser une arête de coupe prédéterminée présentant une pente entre le début et l'extrémité de la découpe, réalisant une forme courbe continue de longueur et profondeur désirées, des moyens permettant d'entraîner en rotation synchrone lesdits moyens en forme de tambours par rapport audit matériau en déplacement et comprenant des moyens pour commander la rotation desdits moyens en forme de tambours agencés de telle sorte que, à l'état inactif, les faces planes des deux tambours sont maintenues rigidement en face l'une de l'autre sans contact avec le matériau en déplacement, et que, dans un mode actif, lesdits deux tambours commencent à tourner en des sens opposés, mais dans le sens de déplacement du matériau, de manière à amener lesdits moyens en forme de couteaux courbes situés sur chaque tambour en contact coopérant avec ledit matériau afin de réaliser ledit cisaillement et ledit enlèvement de ladite partie prédéterminée dudit matériau.Another object of the present invention is to provide an apparatus for shearing and eliminating a predetermined part along at least a first longitudinal edge of a moving metallic material, comprising drum-shaped means located along this first longitudinal edge and comprising at least two rotary drums distant from one another and cooperating with each other and each of which has an axis of rotation and between which said edge of said material circulates, means for supporting, in console, said drums transversely by relative to said material so that their axes are aligned with each other in a vertical plane, and to maintain said drums in a shear and non-shear position with respect to said material, said drums having curved and planar faces cooperating respectively between them, means in the form of curved knives mounted on said curved faces of said drums and made and age ncés so as to achieve a predetermined cutting edge having a slope between the beginning and the end of the cut, achieving a continuous curved shape of desired length and depth, means for driving in synchronous rotation said means in the form of drums with respect to said moving material and comprising means for controlling the rotation of said means in the form of drums arranged so that, in the inactive state, the planar faces of the two drums are held rigidly opposite each other without contact with the moving material, and that, in an active mode, said two drums begin to rotate in opposite directions, but in the direction of movement of the material, so as to bring said means in the form of curved knives located on each drum in contact cooperating with said material in order to achieve said shearing and said removal of said predetermined part of said material.

Ces objectifs et avantages ainsi que d'autres objectifs et avantages de la présente invention seront mieux appréciés et compris à la lecture de la description qui va suivre d'une forme de réalisation préférée, en référence aux dessins annexés, sur lesquels :

Le dispositif d'entaillage de la présente invention a une application particulière dans une chaîne de traitement de bandes en continu, comme par exemple une chaîne d'électrogalvanisation ou un laminoir servant à laminer une bande métallique à froid, comme par exemple en acier ou en aluminium, possédant une épaisseur comprise entre 1,5 mm et 6,5 mm, et dans laquelle la bande se déplace généralement en étant disposée à plat horizontalement.The notching device of the present invention has a particular application in a continuous strip processing line, such as for example an electropalvanization chain or a rolling mill used to cold roll a metal strip, such as for example steel or aluminum, having a thickness between 1.5 mm and 6.5 mm, and in which the strip generally moves by being placed flat horizontally.

Le dispositif d'entaillage rotatif de type actuel ainsi que celui conforme à la présente invention est situé directement en aval d'une soudeuse et en amont d'une fosse d'accumulation ou de stockage et fonctionne selon une relation temporelle par rapport à la soudeuse après que deux bandes, respectivement de largeurs identiques ou différentes, ont été soudées ensemble. La soudeuse peut être d'un de plusieurs types bien connus, comme par exemple une machine à souder par étincelage ou une soudeuse à arc à cisaillement.The current type rotary notching device as well as that according to the present invention is located directly downstream of a welder and upstream of an accumulation or storage pit and operates according to a time relationship with respect to the welder after two strips, respectively of identical or different widths, have been welded together. The welder can be one of several well known types, such as a flash welder or a shear arc welder.

En se référant tout d'abord à la figure 1, le dispositif d'entaillage 10 est monté sur une embase 12 disposée sur le plancher ou le sol de l'usine, transversalement par rapport à la dimension longitudinale de la bande 14. Il comporte deux carters en vis-à-vis 16 et 18, qui sont montés sur l'embase 12 sur des pistes 19, sur lesquelles ils sont déplacés au moyen de vérins hydrauliques 21 vers la gauche et vers la droite de la figure 1, comme cela est indiqué par la flèche double marquée sur chaque carter 16 et 18.Referring first to Figure 1, the notching device 10 is mounted on a base 12 disposed on the floor or the floor of the factory, transversely to the longitudinal dimension of the strip 14. It comprises two casings facing each other 16 and 18, which are mounted on the base 12 on tracks 19, on which they are moved by means of hydraulic cylinders 21 to the left and to the right of FIG. 1, like this is indicated by the double arrow marked on each housing 16 and 18.

Deux têtes porte-tambour supérieure et inférieure 20, distantes l'une de l'autre, sont supportées en porte-à-faux et montées rotatives dans le carter 16 par l'intermédiaire de bouts d'arbres 22, et de façon analogue deux têtes porte-tambour 24 distantes l'une de l'autre sont supportées en porte-à-faux avec possibilité de rotation, sur des bouts d'arbres 26 dans le carter 18.Two upper and lower drum holder heads 20, spaced from one another, are supported in cantilever and rotatably mounted in the casing 16 by means of shaft ends 22, and similarly two drum-holder heads 24 distant from each other are supported in overhang with possibility of rotation, on ends of shafts 26 in the casing 18.

Comme cela est représenté sur la gauche et sur la droite de la figure 1, les têtes associées de chaque couple 20, 24, sont disposées l'une par rapport à l'autre de manière à permettre à la bande 14 de circuler entre elles en position horizontale à plat.As shown on the left and right of Figure 1, the associated heads of each pair 20, 24, are arranged relative to each other so as to allow the strip 14 to flow between them in a horizontal flat position.

Sur les figures 2 et 3 une flèche indique sur la bande 14, le sens de déplacement de celle-ci et, comme cela est représenté sur les figures 1 à 3, les têtes coopérant l'une avec l'autre de chaque couple 20, 24, sont positionnées en travers de la largeur de la bande 14 et sont associées à des bords longitudinaux opposés de cette bande.In FIGS. 2 and 3 an arrow indicates on the strip 14, the direction of movement of the latter and, as shown in FIGS. 1 to 3, the heads cooperating with each other of each pair 20, 24, are positioned across the width of the strip 14 and are associated with opposite longitudinal edges of this strip.

Comme le montre la figure 3, les têtes d'un couple 20 coopérant l'une avec l'autre de même que les têtes 24, sont entraînées par un système d'engrenages 28 sur lequel on va donner brièvement un peu plus de détails.As shown in Figure 3, the heads of a couple 20 cooperating with each other as well as the heads 24, are driven by a gear system 28 on which we will briefly give a little more detail.

Chaque tambour porte-tête 20, 24 est essentiellement cylindrique et, comme cela est représenté en particulier sur la figure 3, possède une face pla- r.e 30 et une face courbe 32, sur laquelle est montée une lame ou un couteau courbe 34 destiné à coopérer avec le tambour, qui lui est associé, pour réaliser le long de celui-ci une découpe en forme d'entaille. Les figures 1 à 3 montrent la courbure du couteau courbe 34, et la configuration courbe de la zone entaillée le long des bords longitudinaux de la bande est représentée uniquement sur la figure 2.Each head drum 20, 24 is essentially cylindrical and, as shown in particular in FIG. 3, has a flat face 30 and a curved face 32, on which is mounted a blade or a curved knife 34 intended for cooperate with the drum, which is associated with it, to carry out along the latter a cut in the form of a notch. FIGS. 1 to 3 show the curvature of the curved knife 34, and the curved configuration of the notched area along the longitudinal edges of the strip is shown only in FIG. 2.

La courbure de la lame courbe 34 présente une inclinaison uniforme et continue depuis un bord périphérique 35 d'une face intérieure 36 de la surface cylindrique ou courbe 32 de chaque tête 20, 24, sur environ 270 degrés jusqu'à un autre bord périphérique 38 le long de la même face intérieure 36 des têtes 20, 24 porte-tambour, laquelle face 36 de chaque tête est tournée vers l'axe médian de la bande 14. On notera que l'on peut modifier la longueur et la forme de la partie découpée de manière à s'adapter à un nombre de conditions différentes désirées, par modification de la longueur et de la courbe des couteaux.The curvature of the curved blade 34 has a uniform and continuous inclination from a peripheral edge 35 of an inner face 36 of the cylindrical or curved surface 32 of each head 20, 24, over about 270 degrees to another peripheral edge 38 along the same inner face 36 of the heads 20, 24 drum holder, which face 36 of each head is turned towards the median axis of the strip 14. It will be noted that the length and the shape of the cut part can be modified so as to adapt to a number of different desired conditions, by modifying the length and the knife curve.

Les têtes 20, 24, qui coopèrent entre elles, de chaque couple de têtes coopérantes sont montées rotatives et sont entraînées en synchronisme par l'intermédiaire d'un système d'engrenages sans jeu 28 au moyen d'un ensemble moteur 40 à courant continu.The heads 20, 24, which cooperate with each other, of each pair of cooperating heads are rotatably mounted and are driven in synchronism by means of a backlash-free gear system 28 by means of a DC motor assembly 40 .

Lorsque le dispositif d'entaillage rotatif 10 conforme à la présente invention est dans un mode inactif, les têtes 20 et 24 sont orientées de manière que les surfaces planes 30 des tambours soient disposées directement au voisinage des faces planes supérieure et inférieure de la bande 14. Dans ce mode inactif, la bande 14 est maintenue écartée des têtes 20, 24 porte-tambour par un dispositif de commande 42, de façon à pouvoir se déplacer librement entre les têtes 20 et 24 sans venir les heurter.When the rotary notching device 10 according to the present invention is in an inactive mode, the heads 20 and 24 are oriented so that the flat surfaces 30 of the drums are arranged directly in the vicinity of the upper and lower planar faces of the strip 14 In this inactive mode, the strip 14 is kept apart from the heads 20, 24 drum holder by a control device 42, so as to be able to move freely between the heads 20 and 24 without striking them.

Lorsque le dispositif d'entaillage rotatif conforme à la présente invention est dans un mode actif, le signal de fin de soudure délivré par la soudeuse 44 est transmis par l'intermédiaire de la ligne 46 au dispositif de commande 42, ainsi que la vitesse de la bande 14, transmise par l'intermédiaire de la ligne 48, laquelle vitesse est contrôlée par un couple de rouleaux de pincement dont l'un est représenté en 50 sur la figure 2. Le fonctionnement de l'ensemble moteur 40 à courant continu est commandé par l'intermédiaire d'une ligne 52 et le joint tel qu'il est formé par soudage (figure 2) de la bande 14 se rapproche de l'ensemble formant dispositif d'entaillage rotatif 10, chaque tête 20, 24 d'une paire étant entraînée en rotation en synchronisme avec la vitesse de la bande 14 en déplacement, dans un sens opposé à celui de la tête porte-tambour, qui lui est associée, pour amener sa surface courbe 32 dans une position adjacente à la surface de la bande, afin que les couteaux courbes 34 entrent en contact avec les faces supérieure et inférieure de la bande 14.When the rotary notching device according to the present invention is in an active mode, the end of weld signal delivered by the welder 44 is transmitted via line 46 to the control device 42, as well as the speed of the strip 14, transmitted via the line 48, which speed is controlled by a pair of pinch rollers, one of which is shown at 50 in FIG. 2. The operation of the DC motor assembly 40 is controlled via a line 52 and the joint as it is formed by welding (figure 2) the strip 14 approaches the assembly forming a rotary notching device 10, each head 20, 24 of a pair being driven in rotation in synchronism with the speed of the strip 14 in movement, in a direction opposite to that of the door head - drum, which is associated therewith, to bring its curved surface 32 into a position adjacent to the surface of the strip, so that the curved knives 34 come into contact with the upper and lower faces of the strip 14.

Lors de cette rotation, une action de découpage ponctuel commence à partir d'un bord extrême 53 en progressant vers l'intérieur en direction de la ligne médiane de la bande, dans une zone s'étendant au niveau du joint soudé 54 (figure 2), où les bandes réunies peuvent ne pas avoir été soudées, jusqu'à la zone soudée et en retour à nouveau en direction d'un bord extrême 55 de la bande, opposé au point où l'action de coupe à commencé. Une courbe uniforme continue et étendue est ménagée dans la bande 14 comme cela est représenté en 56 et en 58 sur la figure 2, sans aucune arête vive ni aucun bord rugueux au voisinage du joint soudé, et la longueur de la découpe 56, 58 réalisée à l'aide du couteau depuis le bord 53 jusqu'au bord 55 est égale à un maximum d'environ 3 mm.During this rotation, a punctual cutting action begins from an extreme edge 53 progressing inward towards the center line of the strip, in an area extending at the level of the welded joint 54 (FIG. 2 ), where the joined strips may not have been welded, to the welded area and back again towards an extreme edge 55 of the strip, opposite the point where the cutting action started. A continuous and extended uniform curve is formed in the strip 14 as shown in 56 and 58 in FIG. 2, without any sharp edge or any rough edge in the vicinity of the welded joint, and the length of the cut 56, 58 made using the knife from edge 53 to edge 55 is equal to a maximum of about 3 mm.

Etant donné qu'une partie entaillée de la bande 14 est retirée, il n'est pas nécessaire de réaliser le soudage sur toute la largeur de la bande, le long de la jonction des deux bandes, en particulier lorsque l'on utilise une soudeuse à arc. C'est pourquoi lors du processus de soudage, l'opérateur peut réduire la durée de soudage en sautant les parties devant être entaillées et en soudant uniquement la zone centrale de la bande où l'entaillage n'est pas réalisé. Après le processus de soudage, les rouleaux de pincement 50 sont entraînés de manière à déclencher l'accélération de la bande dans la chaîne, et c'est à cet instant que la présente invention entre en jeu, comme cela a été décrit ci-dessus.Since a notched part of the strip 14 is removed, it is not necessary to carry out the welding over the entire width of the strip, along the junction of the two strips, in particular when a welder is used. arc. This is why during the welding process, the operator can reduce the welding time by skipping the parts to be cut and by welding only the central zone of the strip where the notching is not carried out. After the welding process, the pinch rollers 50 are driven so as to trigger the acceleration of the strip in the chain, and it is at this instant that the present invention comes into play, as described above. .

La profondeur de la découpe interne 56, 58 en direction de la ligne médiane de la bande est déterminée par le positionnement transversal des têtes 20 et 24 sur l'embase 12 conformément à la largeur de la bande 14, et ce positionnement peut être préréglé en fonction de la largeur de la ou des bandes, lorsqu'elles sont déroulées dans la chaîne ou le laminoir. Etant donné que la vitesse périphérique des couteaux sera toujours synchronisée avec la bande, on a la possibilité d'utiliser toute la longueur et par conséquent toute la profondeur des couteaux ou seulement une partie de cette profondeur, seule la partie inférieure, telle qu'elle est visible sur la figure 2, étant utilisée dans ce cas. Si l'on réunit deux bandes ayant des largeurs différentes, l'ajustement des têtes dépend de la bande possédant la largeur maximum et les têtes 20 et 24 étant positionnées par rapport à la bande de façon à obtenir toujours une découpe selon une courbe uniforme et continue le long du joint soudé ou jusqu'à la section soudée du joint formée par une soudeuse à arc à cisaillement, sans aucun bord rugueux, comme cela est représenté sur la figure 2. La différence de largeur pour des bandes assemblées 14 est comprise entre O et 5,6 mm, pour l'obtention d'une efficacité optimale de la présente invention.The depth of the internal cutout 56, 58 in the direction of the center line of the strip is determined by the transverse positioning of the heads 20 and 24 on the base 12 in accordance with the width of the strip 14, and this positioning can be preset by depending on the width of the strip (s), when they are unwound in the chain or the rolling mill. Since the peripheral speed of the knives will always be synchronized with the strip, it is possible to use the entire length and therefore the entire depth of the knives or only part of this depth, only the lower part, as it is visible in Figure 2, being used in this case. If two strips having different widths are combined, the adjustment of the heads depends on the strip having the maximum width and the heads 20 and 24 being positioned relative to the strip so as to always obtain a cut according to a uniform curve and continues along the welded joint or to the welded section of the joint formed by a shear arc welder, without any rough edge, as shown in FIG. 2. The difference in width for assembled strips 14 is between 0 and 5.6 mm, for obtaining optimum efficiency of the present invention.
