TOLE METALLIQUE GRAVEE A MOTIF REPETITIF REPETITIVE REPETITIVE PATTERNED METAL SHEET
Domaine de l'invention L'invention concerne une tôle métallique gravée à motif répétitif du type " grain de riz " obtenue par une passe finale de laminage effectuée à l'aide d'un cylindre gravé portant l'empreinte négative du motif que l'on souhaite obtenir sur la tôle. Des tôles de ce type sont destinées à la décoration ou à des applications industrielles telles que FIELD OF THE INVENTION The invention relates to an engraved metal sheet with repetitive pattern of the "rice grain" type obtained by a final rolling pass made using an engraved cylinder bearing the negative imprint of the pattern that the we want to get on the sheet. Sheets of this type are intended for decoration or industrial applications such as
des planchers de véhicules industriels. floors of industrial vehicles.
Etat de la technique Il existe déjà sur le marché différents modèles de tôles gravées à motif répétitif souvent désigné de manière imagée: damier, grain d'orge, amande, etc. Elles sont décrites dans la norme NF- EN-1386 ou DIN 59605. Ces tôles doivent satisfaire aux diverses propriétés requises par l'utilisateur et leur fabrication est soumise à un certain nombre d'exigences chez le producteur Pour le fabricant, la gravure du cylindre de laminage représente un investissement important, surtout s'il veut produire des tôles ou bandes en grande largeur. Il souhaite donc que le cylindre ait une durée de vie aussi longue que possible. Dans ce but, il est préférable d'utiliser un procédé de gravure mécanique, plutôt qu'une gravure STATE OF THE ART There are already on the market various models of engraved plates with repeating pattern often pictorially designated: checkerboard, barley grain, kernel, etc. They are described in standard NF-EN-1386 or DIN 59605. These sheets must satisfy the various properties required by the user and their manufacture is subject to a number of requirements at the producer. For the manufacturer, the engraving of the cylinder The rolling mill represents a major investment, especially if it wants to produce sheets or strips in wide width. He wants the cylinder to last as long as possible. For this purpose, it is preferable to use a mechanical etching process, rather than an etching
chimique. Ceci n'est possible que si le motif n'est pas trop fin. chemical. This is only possible if the pattern is not too thin.
D'autre part, pour réduire l'usure du cylindre, assurer une bonne planéité de la tôle et éviter les criques et défauts de surface apparents sur les parties non-gravées de la tôle, il faut que, lors du contact entre la tôle et le cylindre, le métal " monte " facilement dans les creux de la gravure du cylindre, ce qui nécessite que la fraction de surface On the other hand, to reduce the wear of the cylinder, ensure a good flatness of the sheet and avoid cracks and surface defects apparent on the non-etched parts of the sheet, it is necessary that, during contact between the sheet and the cylinder, the metal "mounts" easily into the hollows of the engraving of the cylinder, which requires that the fraction of surface
gravée en creux sur le cylindre soit suffisante et le motif pas trop fin. engraved on the cylinder is sufficient and the pattern is not too thin.
L'utilisateur qui réalise avec la tôle des planchers industriels souhaite de son côté une bonne résistance à l'usure et au frottement et une limitation du bruit, généré en particulier par les engins roulants tels que les chariots. Cette dernière condition The user who realizes with the sheet of the industrial floors wishes for its part a good resistance to wear and friction and a limitation of the noise, generated in particular by the rolling machines such as the carriages. This last condition
demande notamment que le motif soit suffisamment fin. asks in particular that the reason be sufficiently fine.
L'ensemble de ces exigences plus ou moins contradictoires fait que les gravures All of these more or less contradictory requirements make engravings
existant sur le marché ne sont pas totalement satisfaisantes. existing on the market are not totally satisfactory.
But de l'invention L'invention a pour but d'offrir une tôle gravée qui soit aisée à laminer à l'aide d'un cylindre qu'on puisse graver par gravure mécanique et qui présente des propriétés OBJECT OF THE INVENTION The object of the invention is to provide an engraved plate which is easy to laminate with the aid of a cylinder which can be etched by mechanical etching and which has properties
d'emploi satisfaisantes, notamment pour le marché des planchers industriels. satisfactory use, especially for the industrial floor market.

Description de l'inventionDescription of the invention
La description sera faite en se référant à l'exemple représenté sur les figures. Le motif The description will be made with reference to the example shown in the figures. The reason
de la tôle gravée est constitué de plusieurs (2 sur l'exemple représenté) demi-ovoïdes en relief de taille identique, dont la section par le plan de la surface non gravée de la tôle est un ensemble d'ovales ayant des grands axes parallèles et des petits axes colinéaires. Ce motif de base est entouré de 4 motifs identiques, de sorte que, sur des bandes parallèles aux grands axes et aux petits axes, on ait une succession régulièredu motif de base et du même motif après rotation de 90 . Pour assurer une meilleure montée du métal à la gravure, la direction du motif est, de préférence, orientée à of the engraved plate consists of several (2 on the example shown) half-ovoid relief of identical size, whose section by the plane of the ungraved surface of the sheet is a set of ovals having large parallel axes and small collinear axes. This basic pattern is surrounded by 4 identical patterns, so that on strips parallel to the major axes and minor axes, there is a regular succession of base pattern and the same pattern after rotation of 90. To ensure a better rise of the metal during etching, the direction of the pattern is preferably oriented towards
environ 45 par rapport à la direction de laminage. about 45 relative to the rolling direction.
La demanderesse a découvert que la modification, par rapport à l'art antérieur, d'un certain nombre de paramètres dimensionnels du motif pouvait conduire à une amélioration significative et conjointe de plusieurs propriétés d'emploi: réduction du bruit de roulement, meilleure montée de la gravure au laminage, meilleure planéité de The applicant has discovered that the modification, compared with the prior art, of a certain number of dimensional parameters of the pattern could lead to a significant and joint improvement of several employment properties: reduction of rolling noise, better increase of the rolling engraving, better flatness of
la tôle gravée.the engraved plate.
i5 Dans ce but, la longueur de chaque relief du motif correspondant au grand axe de l'ovale de section avec la plan de la surface non gravée de la tôle, doit être comprise entre 5 et 10 min, et de préférence entre 7 et 10 mm La largeur du relief; correspondant au petit axe de l'ovale, doit être compris entre 2,5 et 4 mm, et de préférence entre 2,5 et 3 min. Le pas du motif c'est-à-dire la distance, mesurée dans le sens du laminage, par laquelle le motif se reproduit à l'identique, est compris entre 12 et 15 mm, ce qui conduit à une fraction de surface gravée comprise entre 30 et %. La hauteur maximale du relief est comprise de préférence entre 1,3 et 2 mm Le motif en relief de la tôle gravée est obtenu par laminage à l'aide d'un cylindre gravé portant en creux l'empreinte négative du relief de la tôle. Les dimensions selon l'invention permettent de réaliser le motif par gravure mécanique, et non chimique, qui permet d'utiliser un acier durci, ce qui assure au cylindre une durée de vie accrue et permet la réalisation d'un motif aux contours nets. De plus, il est possible d utiliser des cylindres de grande largeur pour graver des tôles de plus de 2 m de large, voire de For this purpose, the length of each relief of the pattern corresponding to the major axis of the sectional oval with the plane of the unetched surface of the sheet must be between 5 and 10 min, and preferably between 7 and 10. mm The width of the relief; corresponding to the minor axis of the oval, should be between 2.5 and 4 mm, and preferably between 2.5 and 3 min. The pitch of the pattern, that is to say the distance, measured in the direction of rolling, by which the pattern reproduces identically, is between 12 and 15 mm, which leads to an engraved area fraction included between 30 and%. The maximum height of the relief is preferably between 1.3 and 2 mm. The embossed pattern of the etched sheet is obtained by rolling with the aid of an engraved roll bearing in hollow the negative imprint of the relief of the sheet. The dimensions according to the invention make it possible to produce the pattern by mechanical etching, and non-chemical, which makes it possible to use a hardened steel, which assures the roll a longer life and allows the realization of a pattern with sharp outlines. In addition, it is possible to use large cylinders to engrave sheets of more than 2 m wide, or even
plus de 2,5 mi de large.more than 2.5 mi wide.
Les tôles gravées selon l'invention présentent un motif net sur une surface non gravée bien plane et exempte de criques et autres défauts de surface, ce qui les rend apte à des emplois décoratifs, tels que des panneaux muraux ou d'ascenceurs. Grice au faible niveau de bruit occasionné par le roulement des chariots et leur bonne résistance à l'usure, elles peuvent être utilisées comme planchers de véhicules industriels, par The etched sheets according to the invention have a clean pattern on a non-etched surface that is flat and free of cracks and other surface defects, which makes them suitable for decorative purposes, such as wall panels or elevators. Thanks to the low noise level caused by the rolling of the trolleys and their good resistance to wear, they can be used as floors for industrial vehicles, for example
exemple des camions frigorifiques.example of refrigerated trucks.
ExempleExample
On a réalisé des tôles gravées selon le dessin des figures 1 à 3 avec les caractéristiques dimensionnelles suivantes: longueur du relief demiovoïde: 8,4 mm largeur du relief 2,8 mm hauteur du relief 1,5 mm pas du motif dans le sens du laminage: 13,3 mm fraction de surface gravée: 34,5% On a comparé ces tôles à des tôles d'un motif << grain d'orge " de l'art antérieur de dessin assez voisin, mais présentant les dimensions suivantes: longueur: 7,5 mm largeur: 2,3 mm hauteur: 1,25 mm pas: 11,3% fraction de surface gravée: 34,9% Le cylindre utilisé pour les tôles selon l'invention,de diamètre 615 mm et de largeur gravée 2700 mm, a été réalisé par gravure mécanique sur acier 19NC traité pour obtenir une dureté de 620 HV30. Le cylindre pour la gravure " grain d'orge ", de Embossed plates were made according to the drawing of FIGS. 1 to 3 with the following dimensional characteristics: length of the semiovoidal relief: 8.4 mm width of the relief 2.8 mm height of the relief 1.5 mm no pattern in the direction of the rolling: 13.3 mm fraction of etched surface: 34.5% These sheets were compared to sheets of a "barley grain" pattern of the prior art of fairly similar design, but having the following dimensions: length: 7.5 mm width: 2.3 mm height: 1.25 mm pitch: 11.3% fraction of engraved area: 34.9% The cylinder used for the sheets according to the invention, with a diameter of 615 mm and engraved width 2700 mm, was produced by mechanical etching on 19NC steel treated to obtain a hardness of 620 HV30.The cylinder for engraving "barley grain", of
largeur1700 min, a été gravé par gravure chimique sur acier non traité. width1700 min, was engraved by chemical etching on untreated steel.
Dans les deux cas, la gravure a été effectuée sur des tôles en alliage d'aluminium 5086 laminées à froid à l'épaisseur 3,9 mm et à l'état H14. La passe de laminage avec le cylindre gravé a réduit l'épaisseur à 2,85 mm L'effort appliqué pour la montée du relief de gravure a été de 800 t/ mètre de largeur au lieu de 1000 T:M pour la tôle " grain d'orge ". L'écart de planéité a été de l'ordre de 10 mm/m au lieu de 20 mm/m In both cases, the etching was carried out on cold-rolled aluminum alloy sheets 5086 at a thickness of 3.9 mm and in the H14 state. The rolling pass with the engraved cylinder reduced the thickness to 2.85 mm The force applied for the rising of the engraving relief was 800 t / meter width instead of 1000 T: M for the sheet "grain barley ". The flatness difference was of the order of 10 mm / m instead of 20 mm / m
pour les tôles << grain d'orge ".for "barley grain" sheets.
On a réalisé par ailleurs un essai de bruit par roulement d'un chariot à roulettes sur la tôle. La tôle selon l'invention a donné un résultat de l'ordre de 6 décibels au lieu de 8 In addition, a rolling noise test of a trolley with wheels on the sheet was carried out. The sheet according to the invention gave a result of the order of 6 decibels instead of 8
décibels pour la tôle " grain d'orge ". decibels for the "barley grain" sheet.
Ainsi, les caractéristiques dimensionnelles du motif des tôles selon l'invention Thus, the dimensional characteristics of the pattern of the sheets according to the invention
conduisent à un ensemble de propriétés améliorées par rapport à l'art antérieur. lead to a set of improved properties over the prior art.
