Description

DISPOSITIF POUR RECTIFIER EN CONTINU LES BORDS DE RIVE DE FEUILLES METALLIQUES EN MOUVEMENT Objet de l'invention DEVICE FOR CONTINUOUSLY GRINDING THE EDGE EDGES OF MOVING METAL SHEETS Subject of the invention
La présente invention est relative à un dispositif pour rectifier en continu les bords de rives de feuilles mé- talliques en bande en mouvement.The present invention relates to a device for continuously grinding the edges of edges of metallic sheets in moving strip.
Inconvénients des solutions de l'état de la techniqueDisadvantages of prior art solutions
On sait que les bandes de feuilles métalliques lami¬ nées présentent des irrégularités sur les bords de rives, sou¬ vent dénommées dents de scie des bords, qui sont essentielle- ment dues aux bavures de cisaillage des rives après décapage et qui sont amplifiées par le laminage.It is known that the strips of laminated metal sheets have irregularities on the edges of the edges, often called the edge saw teeth, which are essentially due to the shearing burrs of the edges after stripping and which are amplified by the rolling.
Les irrégularités sont d'autant plus marquées que le laminage est poussé et que les épaisseurs de feuille sont faibles. En plus des irrégularités dans le sens transversal de la bande de feuille métallique, celle-ci présente souvent des bavures dans le plan perpendiculaire au plan principal de la bande et principalement dans les bandes cisaillées à la volée. II en résulte une usure prématurée du revêtement des rouleaux d'entraînement et de support de la bande de feuille métallique par suite d'un effort de cisaillement exer¬ cé dans la masse dudit revêtement qui est souvent, dans le cas de lignes de prélaquage, en caoutchouc ou en polyuréthane de faible dureté.The irregularities are all the more marked as the rolling is pushed and the sheet thicknesses are low. In addition to the irregularities in the transverse direction of the strip of metal foil, this often has burrs in the plane perpendicular to the main plane of the strip and mainly in the strips sheared on the fly. This results in premature wear of the coating of the drive rollers and of the support for the strip of metal foil as a result of a shearing force exerted in the mass of said coating which is often, in the case of prepainting lines, made of low hardness rubber or polyurethane.
Cette usure prématurée est amplifiée par l'étale¬ ment des vitesses relatives entre rouleaux et bandes.This premature wear is amplified by the étale¬ ment of the relative speeds between rollers and strips.
Notamment dans le cas de feuilles métalliques revê¬ tues, l'épaisseur du revêtement varie de ce fait sur la lar- geur de ladite feuille métallique.In particular in the case of coated metal sheets, the thickness of the coating therefore varies over the width of said metal sheet.
On obtient par conséquent un produit hon homogène et/ou un produit présentant des défauts dans le revêtement, à savoir des traînées parasites ou des surépaisseurs sur rives. On connaît par le document FR-A-1.365.153 ( . SCHMIDT) un dispositif pour polir ou profiler des arêtes de panneaux de verre et de glaces. Dans ce dispositif il est pré¬ vu que les meules, c'est-à-dire les organes de polissage sont montées sur des bras oscillants doubles. Les meules sont appliquées sur les pièces à traiter par un contrepoids et/ou un ressort de pression.Consequently, a homogeneous hon product and / or a product with defects in the coating is obtained, namely parasitic streaks or excess thickness on the edges. Document FR-A-1.365.153 (. SCHMIDT) is known for a device for polishing or profiling edges of glass panels and glass panes. In this device, it is seen that the grinding wheels, that is to say the polishing members, are mounted on double oscillating arms. The grindstones are applied to the parts to be treated by a counterweight and / or a pressure spring.
Ce document qui concerne un domaine technique tota¬ lement différent de celui auquel s'adresse la présente inven- tion ne permet pas de résoudre les inconvénients précités. Buts visés par l'inventionThis document, which relates to a technical field totally different from that to which the present invention is addressed, does not make it possible to resolve the aforementioned drawbacks. Goals of the invention
La présente invention vise à remédier aux divers inconvénients susmentionnés. un but spécifique de la présente invention consiste a fournir un dispositif qui permet de rectifier en continu les bords de rive de feuilles métalliques en bande.The present invention aims to remedy the various drawbacks mentioned above. a specific aim of the present invention consists in providing a device which makes it possible to continuously rectify the edge edges of metal sheets in strips.
Un autre but spécifique de la présente invention consiste à fournir un dispositif du type susmentionné qui est stable en fonction de la vitesse de défilement de la bande de feuille métallique.Another specific object of the present invention consists in providing a device of the above-mentioned type which is stable as a function of the running speed of the strip of metal foil.
Eléments caractéristiques de l'inventionCharacter-defining elements of the invention
Selon la présente invention, le dispositif du type susmentionné comporte un support fixe monté sur un châssis réglable en hauteur et un support mobile agencé de manière à pouvoir coulisser sur ledit support fixe selon une direction essentiellement perpendiculaire à la direction de défilement de la bande de feuille métallique. Le support mobile comporte un bras pivotant en son centre sur un axe essentiellement ver¬ tical et comportant aux deux extrémités chaque fois un galet de guidage qui prend appui sur un même bord de rive d'une ban¬ de de feuille métallique, un galet de dressage inférieur et un galet de dressage supérieur entre lesquels est serrée et dressée la bande de feuille métallique moyennant une force de pression réglable, un porte-outil amont qui porte au moins un outil de coupe pour le dressage de la tranche de la bande de feuille métallique et un porte-outil aval qui porte au moins un outil de chanfreinage des arêtes supérieure et inférieure, le support mobile étant appliqué contre le bord de rive de la bande de feuille métallique, via les galets de guidage, moyen- nant une force de pression réglable qui prend appui sur le support fixe. On a constaté lors d'essais que le guidage des outils sur les bords de rive à l'aide de galets de guidage montés sur les deux extrémités d'un bras pivotable en son centre est particulièrement avantageux et approprié pour assurer un contact permanent entre les outils et les bords de rive. Avantageusement, le bras pivotable présente une dimension telle que les galets de guidage se trouvent res¬ pectivement en amont et en aval des porte-outils correspon¬ dants, de telle sorte qu'un galet de guidage prend appui sur un bord de rive brut et l'autre galet de guidage prend appui sur un bord de rive rectifié. De cette manière, on obtient une stabilisation adéquate en fonction de la vites¬ se de défilement de la bande.According to the present invention, the device of the aforementioned type comprises a fixed support mounted on a height-adjustable chassis and a mobile support arranged so as to be able to slide on said fixed support in a direction substantially perpendicular to the direction of travel of the sheet strip. metallic. The mobile support comprises an arm pivoting at its center on an essentially vertical axis and comprising at each end each time a guide roller which bears on the same edge of a bank of a sheet of metal, a roller of lower dressing and an upper dressing roller between which the metal foil strip is clamped and erected by means of an adjustable pressing force, an upstream tool holder which carries at least one cutting tool for dressing the edge of the foil strip metal and a downstream tool holder which carries at least one tool for chamfering the upper and lower edges, the movable support being applied against the edge of the edge of the strip of metal sheet, via the guide rollers, providing a force of adjustable pressure which is supported on the fixed support. It has been found during tests that the guiding of the tools on the edge of the edges using guide rollers mounted on the two ends of an arm pivotable in its center is particularly advantageous and suitable for ensuring permanent contact between the tools and the edge edges. Advantageously, the pivotable arm has a dimension such that the guide rollers are res¬ pectively upstream and downstream of the corresponding tool holders, so that a guide roller is supported on a raw edge edge and the other guide roller is supported on a rectified edge edge. In this way, an adequate stabilization is obtained as a function of the speed of travel of the strip.
De préférence, la force de pression réglable qui applique le support mobile via les galets de guidage con- tre le bord de rive comporte une composante active et une composante passive. Selon une forme d'exécution particuliè¬ rement préférée de la présente invention, la composante active consiste en un vérin à pression réglable et la com¬ posantepassive consiste en un ressort. On a constaté que la combinaison de ces deux moyens procure des résultats avantageux, notamment en ce qui concerne la sensibilité aux vibrations, plus particulièrement à vitesse élevée.Preferably, the adjustable pressure force which applies the mobile support via the guide rollers against the edge of the edge comprises an active component and a passive component. According to a particularly preferred embodiment of the present invention, the active component consists of an adjustable pressure cylinder and the passive component consists of a spring. It has been found that the combination of these two means provides advantageous results, in particular as regards sensitivity to vibrations, more particularly at high speed.

- la figure 1 représente une vue schématique de face du dispositif conforme à la présente invention, etFIG. 1 represents a schematic front view of the device according to the present invention, and
- la figure 2 est une vue schématique en plan du dispositif représenté à la figure 1.- Figure 2 is a schematic plan view of the device shown in Figure 1.
En référence aux figures, des repères de référen¬ ce identiques se rapportent à des éléments identiques ou analogues.With reference to the figures, identical reference marks relate to identical or analogous elements.
Le dispositif 1 conforme à la présente invention destiné à rectifier les bords de rive en bandes de feuille métallique 3 comporte un support fixe 5 monté sur un châs¬ sis réglable en hauteur (non représenté), et un support mobile 7 qui peut coulisser sur des guides 9 solidaires du support fixe 5. Le support mobile 7 comporte un bras 11 monté de manière à pouvoir pivoter sur un axe essentiellement vertical 13 en son centre et muni, à ses deux extrémités, d'un galet de guidage 15 et 17. Lesdits galets de guidage sont avantageusement réglables en hauteur moyennant une tige filetée, respectivement 19 et 21.The device 1 according to the present invention intended to rectify the edge edges into strips of metal foil 3 comprises a fixed support 5 mounted on a height-adjustable frame (not shown), and a mobile support 7 which can slide on guides 9 secured to the fixed support 5. The mobile support 7 comprises an arm 11 mounted so as to be able to pivot on an essentially vertical axis 13 at its center and provided, at its two ends, with a guide roller 15 and 17. Said guide rollers are advantageously adjustable in height by means of a threaded rod, respectively 19 and 21.
Ledit bras pivotant 11 comporte en outre un ga¬ let de dressage inférieur 23 de la feuille métallique, dont l'axe de rotation est fixe et un galet de dressage supé- rieur 25. Avantageusement, ledit galet de dressage supé¬ rieur peut être écarté dudit galet de dressage inférieur à l'aide d'un vérin 27. Ceci facilite le passage d'une cou¬ ture ou d'un agrafage de deux bandes de feuille métallique dans le processus de traitement continu. Selon l'invention, le galet de dressage supérieurSaid pivoting arm 11 further comprises a lower dressing ga¬ 23 of the metal sheet, the axis of rotation of which is fixed and an upper dressing roller 25. Advantageously, said upper dressing roller can be moved apart. said lower dressing roller using a cylinder 27. This facilitates the passage of a cou¬ ture or stapling of two strips of metal foil in the continuous treatment process. According to the invention, the upper facing roller
25 serre, avec une force de pression, de préférence régla¬ ble, la feuille métallique 3 défilant à grande vitesse con¬ tre le galet de dressage inférieur 23 en vue de la dresser à l'endroit de l'usinage à effectuer sur les bords de rive. Ladite force de pression est exercée à l'aide du vérin 27 également.25 clamps, with a pressure force, preferably adjustable, the metal sheet 3 moving at high speed against the lower facing roller 23 in order to straighten it at the location of the machining to be carried out on the edges shore. Said pressing force is exerted by means of the jack 27 also.
On a constaté que l'on obtient les meilleurs ré¬ sultats à l'usinage des tranches de feuilles métalliques 3 défilant à grande vitesse, avec des outils de coupe et en procédant en plusieurs étapes. Un porte-outil amont 29 est pourvu de deux outils de coupe 31 et 33, un outil dé- grossisseur 31 et un outil de finition 33, pour dresser la tranche de la feuille métallique 3. Un porte-outil aval 35 est pourvu de deux outils de chanfreinage, un outil dé- grossisseur 37 et un outil de finition 39.It has been found that the best results are obtained when machining the slices of metal sheets 3 scrolling at high speed, with cutting tools and by proceeding in several stages. An upstream tool holder 29 is provided with two cutting tools 31 and 33, a coarse tool 31 and a finishing tool 33, for dressing the edge of the metal sheet 3. A downstream tool holder 35 is provided with two chamfering tools, a coarse tool 37 and a finishing tool 39.
Avantageusement, les porte-outils 29 et 35 sont montés sur des guides 41, 43 de manière à pouvoir être dé¬ placés perpendiculairement à l'axe de défilement de la ban¬ de 3, sur le bras pivotant 11. II est bien entendu que selon le matériau métal¬ lique à traiter et selon les autres conditions d'utilisa¬ tion, il peut s'avérer avantageux d'utiliser plus de deux outils de dressage et/ou plus de deux outils de chanfreinage successifs.Advantageously, the tool holders 29 and 35 are mounted on guides 41, 43 so as to be able to be moved perpendicular to the axis of travel of the ban 3, on the pivoting arm 11. It is understood that depending on the metallic material to be treated and according to the other conditions of use, it may prove advantageous to use more than two dressing tools and / or more than two successive chamfering.
Tout type d'outil connu en soi pour ce genre d'opération convient dans l'application concernée. On a constaté que pour réduire les frais d'entretien et d'arrêt de la machine, il est avantageux d'utiliser des outils de dressage à quatre tranchants qui permettent de remplacer un couteau par un autre par simple rotation de l'outil.Any type of tool known per se for this kind of operation is suitable for the application concerned. It has been found that in order to reduce the maintenance and stopping costs of the machine, it is advantageous to use dressing tools with four cutting edges which make it possible to replace one knife with another by simply rotating the tool.
Selon une forme d'exécution préférée, l'embout de support du galet de dressage supérieur 25 est équipé d'un patin d'entrée 45 qui facilite le guidage de la feuil¬ le métallique défilante.According to a preferred embodiment, the support end piece of the upper facing roller 25 is equipped with an input pad 45 which facilitates the guiding of the traveling metal sheet.
De préférence, le dispositif conforme à la pré¬ sente invention est équipé d'un moyen d'évacuation des co¬ peaux tel que des buses de soufflage d'air. On peut égale- ment prévoir des moyens pour la projection de lubrifiants ou d'agents réfigérants.Preferably, the device according to the present invention is equipped with a means for removing the skins such as air blowing nozzles. Means can also be provided for spraying lubricants or refrigerants.
Selon une forme d'exécution particulièrement pré¬ férée de la présente invention, le support mobile est ap¬ puyé contre le bord de rive de la bande de feuille métalli- que, via les galets de guidage 15 et 17 à l'aide d'une for¬ ce de pression comportant une composante active et une com¬ posante passive. Ladite force de pression exercée par un ressort 47 et par au moins un vérin 49. De préférence, la composante active est exercée par un vérin à suivre et un vérin de retrait.According to a particularly preferred embodiment of the present invention, the movable support is pressed against the edge of the edge of the metal sheet strip, via the guide rollers 15 and 17 using a pressure force comprising an active component and a passive component. Said pressure force exerted by a spring 47 and by at least one cylinder 49. Preferably, the active component is exerted by a cylinder to be followed and a withdrawal cylinder.
Le présent mémoire descriptif est limité à la description d'un dispositif pour rectifier les bords de rive mais il est bien évident que l'on peut disposer un dispositif du type susmentionné de part et d'autre de la bande de feuille métallique afin de rectifier simultané¬ ment et en continu les deux bords de rive de ladite bande quel que soit le déplacement transversal de cette bande.This specification is limited to the description of a device for rectifying the edge edges but it is obvious that one can have a device of the aforementioned type on either side of the strip of metal foil in order to rectify simultaneously and continuously the two edge edges of said strip whatever the transverse displacement of this strip.
Il est bien évident que la présente invention ne se limite pas au dispositif tel que décrit mais qu'elle s'étend au cadre défini par les revendications. It is obvious that the present invention is not limited to the device as described but that it extends to the framework defined by the claims.
