Abstract

Sheet material with a sandwich structure comprising a web between two metal skins has a pattern imprinted on at least one of the outer surfaces by deformation of the skin. An Independent claim is also included for a method for the production of this material by pressing the sandwich between two rollers, at least one of which is engraved, and deforming at least one of the skins by a stamping process in which the engraving on the roller acts as a matrix for the skin in contact with it and the web (under pressure) acts as a flexible punch for the skin.

Tôle de structure sandwich composée d'une âme insérée entre deux peaux métalliques formant chacune une face du sandwich.  Sandwich structure sheet composed of a core inserted between two metal skins each forming one side of the sandwich.

La présente invention concerne une tôle de structure sandwich composée d'une âme insérée entre deux peaux métalliques formant chacune une face du sandwich.  The present invention relates to a sandwich structure sheet composed of a core inserted between two metal skins each forming a face of the sandwich.

Aujourd'hui, les tôles gravées par exemple en acier inoxydable sont réalisées par laminage ou embossage.  Today, engraved sheets, for example made of stainless steel, are produced by rolling or embossing.

Le laminage est effectué soit à froid soit à chaud sur une tôle soumise à une forte pression entre deux cylindres dont au moins un est gravé. Les reliefs obtenus sont de l'ordre de quelques centièmes à quelques dixièmes de millimètre.  The rolling is carried out either cold or hot on a sheet metal subjected to a high pressure between two rolls of which at least one is engraved. The reliefs obtained are of the order of a few hundredths to a few tenths of a millimeter.

L'embossage est effectué à froid sur une tôle soumise à une forte pression entre deux cylindres dits male et femelle et appariés. Les surfaces de la tôle présentent de ce fait des reliefs en bosse et en creux, sans modification importante de l'épaisseur générale de la tôle mais présentant des problèmes dans le domaine de la mise en oeuvre et de la fixation, les deux surfaces étant systématiquement déformées.  The embossing is carried out cold on a sheet metal subjected to a strong pressure between two cylinders called male and female and paired. The surfaces of the sheet therefore have reliefs in hump and recess, without significant modification of the general thickness of the sheet but presenting problems in the field of implementation and fixing, the two surfaces being systematically distorted.

D'autre part, ces méthodes de réalisations de reliefs sur une tôle métallique ne permettent pas la réalisation de motifs de grande profondeur et nécessite des efforts de tar'nage importants.  On the other hand, these methods of producing reliefs on a metal sheet do not allow the production of patterns of great depth and require significant tarning efforts.

L'invention a pour but de proposer un produit sous forme de tôle métallique et de préférence d'acier inoxydable comportant des reliefs, dont les motifs, très marqués, peuvent avoir des profondeurs de l'ordre du millimètre.  The invention aims to provide a product in the form of metal sheet and preferably stainless steel having reliefs, the patterns, very marked, can have depths of the order of a millimeter.

L'invention a pour objet une tôle de structure sandwich composée d'une âme insérée entre deux peaux métalliques formant chacune une face du sandwich, caractérisée en ce qu'elle présente, sur au moins une de ces faces, des motifs gravés, obtenus par la déformation d'au moins une peau.  The subject of the invention is a sheet of sandwich structure composed of a core inserted between two metal skins each forming one face of the sandwich, characterized in that it has, on at least one of these faces, engraved patterns, obtained by deformation of at least one skin.

Les autres caractéristiques de l'invention sont : - au moins une des peaux métallique est choisie parmi un acier, un acier inoxydable.  The other characteristics of the invention are: - at least one of the metallic skins is chosen from steel, stainless steel.

- l'âme est constituée d'un matériau présentant des caractéristiques mécaniques très inférieures à celle des peaux.  - The core is made of a material with mechanical characteristics much lower than that of the skins.

- l'âme est constituée d'un matériau métallique ou synthétique.  - the core is made of a metallic or synthetic material.

- l'âme est constituée d'un matériau métallique choisi parmi l'aluminium, le plomb, le cuivre.  - the core consists of a metallic material chosen from aluminum, lead, copper.

- l'âme est constituée d'un matériau synthétique choisi parmi les thermoplastiques, le polypropylène, le polyéthylène, le poly butène.  - The core consists of a synthetic material chosen from thermoplastics, polypropylene, polyethylene, poly butene.

L'invention concerne également un procédé de réalisation d'une tôle gravée de structure sandwich composée d'une âme insérée entre deux peaux métalliques formant chacune une face du sandwich, caractérisé en ce que : - on presse la tôle sandwich entre deux cylindres dont au moins un des cylindres présente des gravures, - on déforme au moins une des peaux, par un phénomène d'emboutissage, les gravures d'un cylindre ayant pour fonction celle d'une matrice pour la peau en contact avec celui-ci, et l'âme, mise sous pression, ayant la fonction d'un poinçon souple pour ladite peau.  The invention also relates to a process for producing an engraved sheet of sandwich structure composed of a core inserted between two metal skins each forming one face of the sandwich, characterized in that: - the sandwich sheet is pressed between two cylinders, of which at least one of the cylinders has engravings, - at least one of the skins is deformed, by a stamping phenomenon, the engravings of a cylinder having the function of that of a matrix for the skin in contact with it, and l 'soul, pressurized, having the function of a flexible punch for said skin.

Les autres caractéristiques du procédé sont : - en outre, et préalablement à la réalisation des motifs gravés, on préchauffe la tôle de structure sandwich afin d'amener le matériau de l'âme à un degré de plasticité et ou de fluage adapté.  The other characteristics of the process are: - in addition, and prior to the production of the engraved patterns, the sandwich structure sheet is preheated in order to bring the material of the core to a suitable degree of plasticity and / or creep.

La description qui suit et les figures annexées, le tout donné à titre d'exemple non limitatif, fera bien comprendre l'invention.  The following description and the appended figures, all given by way of nonlimiting example, will make the invention clear.

La figure unique présente une photographie d'un exemple de tôle selon l'invention.  The single figure presents a photograph of an example sheet according to the invention.

La tôle de structure sandwich, selon l'invention, est composée d'une âme comprise entre 1 mm et 5 mm d'é aisseur, pouvant être, par exemple, en polypropylène et insérée entre deux pea, x métalliques de préférence en acier, l'une étant, par exemple, en acier inoxydable de 0,1 mm à 0,5 mm d'épaisseur, l'autre en acier galvanisé de 0,1 mm et 0,5 mm d'épaisseur, formant chacune une face du sandwich.  The sandwich structure sheet, according to the invention, is composed of a core of between 1 mm and 5 mm of spreader, which can be, for example, made of polypropylene and inserted between two metallic pegs, preferably steel, one being, for example, in stainless steel 0.1 mm to 0.5 mm thick, the other in galvanized steel 0.1 mm and 0.5 mm thick, each forming a face of the sandwich.

Pour la réalisation de motifs gravés, sur au moins une des faces du sandwich : - on presse la tôle sandwich entre deux cylindres d'un laminoir dont au moins un des cylindres présente des gravures, - on déforme au moins une des peaux, par un phénomène d'emboutissage, les gravures de cylindre ayant pour fonction celle d'une matrice et l'âme, matériau présentant une caractéristique de fluage sous charge importante, mise sous pression, ayant la fonction d'un poinçon souple.  To produce engraved patterns, on at least one of the faces of the sandwich: - the sandwich plate is pressed between two rolls of a rolling mill, at least one of the rolls of which has engravings, - at least one of the skins is deformed by a stamping phenomenon, the cylinder engravings having for function that of a matrix and the core, material having a characteristic of creep under heavy load, pressurized, having the function of a flexible punch.

En outre, et préalablement à la réalisation des motifs gravés, on préchauffe la tôle de structure sandwich afin d'amener le matériau de l'âme à un degré de plasticité et ou de fluage adapté.  In addition, and prior to the production of the engraved patterns, the sandwich structure sheet is preheated in order to bring the material of the core to a suitable degree of plasticity and or creep.

L'allongement moyen du métal de la peau emboutie peut atteindre 50%. Les déformations générées pourront être de type aléatoire comme par exemple, crépi,  The average metal elongation of the stamped skin can reach 50%. The deformations generated may be of random type such as, for example, roughcast,

<Desc/Clms Page number 3><Desc / Clms Page number 3>

grenaillé, ou de type géométriquement organisé comme par exemple, pyramide, drapé, grain d'orge.  shot blasted, or of a geometrically organized type such as, for example, pyramid, draped, grain of barley.

La déformation de la peau s'effectue par le fluage ou déplacement adapté de l'âme par exemple synthétique. Cette déformation permet l'obtention de rugosités ou de reliefs de l'ordre du mm voire plus, en fonction de l'épaisseur du sandwich ou de l'âme.  The deformation of the skin is effected by creep or adapted displacement of the, for example synthetic, core. This deformation makes it possible to obtain roughness or reliefs of the order of mm or more, depending on the thickness of the sandwich or of the core.

Soumis à la pression, le matériau métallique ou synthétique flue ou se déforme et se déplace dans les zones de moindre pression, creux des gravures, dans lesquels il fait office de poinçon. Ainsi, la peau en acier se déforme sous la pression et épouse la géométrie de la gravure d'au moins un cylindre.  When subjected to pressure, the metallic or synthetic material flows or deforms and moves in the areas of least pressure, hollow in the engravings, in which it acts as a punch. Thus, the steel skin deforms under pressure and follows the geometry of the engraving of at least one cylinder.

La finesse des motifs réalisés dépend de l'épaisseur de la peau déformée, de la géométrie des reliefs, de l'épaisseur de l'âme en matériau synthétique, de la pression exercée sur la tôle sandwich de base par les cylindres de laminoir.  The fineness of the patterns produced depends on the thickness of the deformed skin, on the geometry of the reliefs, on the thickness of the core in synthetic material, on the pressure exerted on the basic sandwich sheet by the rolling mill rolls.

La déformation d'au moins une peau peut être effectuée à chaud, comme par exemple à 70 C dans le cas d'une âme en polypropylène, juste au-dessus de 60 C qui est le DHT (High Deflection Temperature) de ce matériau synthétique.  The deformation of at least one skin can be carried out hot, for example at 70 C in the case of a polypropylene core, just above 60 C which is the DHT (High Deflection Temperature) of this synthetic material .

De ce fait, il est possible de réaliser une tôle sandwich selon l'invention en sortie de ligne de thermo-collage, lors de la réalisation de la tôle sandwich de base.  As a result, it is possible to produce a sandwich sheet according to the invention at the outlet of the heat-bonding line, during the production of the basic sandwich sheet.

D'autres matériaux synthétiques peuvent être utilisés comme poinçon soupl. par exemple les thermoplastiques, le polyéthylène, le poly butène.  Other synthetic materials can be used as a flexible punch. for example thermoplastics, polyethylene, poly butene.

Pour éviter une trop grande répétition des motifs, les diamètres des cylindres de laminoir sont adaptés aux dimensions des motifs. Les cylindres standards ont un diamètre de 100 mm à 1000 mm et une longueur de l'ordre de 1500 mm. Ils peuvent être montés sur un laminoir duo ou quarto. La déformation peut être réalisée par le laminoir en une ou plusieurs passes en fonction de la profondeur et de la géométrie de la gravure.  To avoid excessive repetition of the patterns, the diameters of the rolling mill rolls are adapted to the dimensions of the patterns. Standard cylinders have a diameter of 100 mm to 1000 mm and a length of the order of 1500 mm. They can be mounted on a duo or quarto rolling mill. The deformation can be carried out by the rolling mill in one or more passes depending on the depth and the geometry of the engraving.

Le procédé selon l'invention permet la réalisation des tôles en appliquant entre cylindres une charge de l'ordre de 200 Kg par centimètre soit un effort d'environ 30 tonnes, alors que les procédés classiques cités de l'art antérieur demandent des efforts 10 fois plus élevés.  The method according to the invention allows the production of sheets by applying between cylinders a load of the order of 200 Kg per centimeter, ie an effort of approximately 30 tonnes, whereas the conventional methods cited in the prior art require efforts 10 times higher.

Plusieurs procédés de gravure peuvent être utilisés pour le marquage des cylindres : - l'utilisation de résines disposées en film sur le cylindre, les motifs étant gravés par la destruction d'une partie du film au moyen d'un laser YAG (grenat d'yttrium), - gravure chimique, mécanique, électrochimique, physique (Laser).  Several engraving methods can be used for marking cylinders: - the use of resins arranged in film on the cylinder, the patterns being engraved by the destruction of part of the film by means of a YAG laser (garnet of yttrium), - chemical, mechanical, electrochemical, physical (Laser) etching.

<Desc/Clms Page number 4> <Desc / Clms Page number 4>

- le décapage classique du cylindre. Le fond de la gravure chimique étant rugueux, un polissage électrochimique peut être effectué pour éliminer ladite rugosité. - conventional stripping of the cylinder. The background of the chemical etching being rough, an electrochemical polishing can be carried out to eliminate said roughness.

L'invention permet la réalisation d'une tôle sandwich présentant des motifs gravés à hauts reliefs de l'ordre du mm, sous des pressions de laminoir relativement faibles, tôle de faible densité surfacique permettant la réalisation de panneaux légers. La tôle selon l'invention peut comporter des motifs gravés sur une seule de ces faces, pour une réduction des frais de gravure de cylindre, ou encore deux faces gravées de motifs différents adaptés. Une face, de la tôle, qui peut être lisse ou avec des motifs adaptés de faibles reliefs, facilite la mise en oeuvre et la fixation de la tôle selon l'invention. The invention allows the production of a sandwich sheet having etched patterns with high reliefs of the order of mm, under relatively low rolling mill pressures, sheet of low surface density allowing the production of light panels. The sheet according to the invention may include patterns engraved on only one of these faces, for a reduction in cylinder engraving costs, or even two faces engraved with different suitable patterns. One side of the sheet, which can be smooth or with patterns suitable for small reliefs, facilitates the implementation and fixing of the sheet according to the invention.
