Description
261397R261397R
La présente invention concerne un appareil fixe à découpe verticale pour scier des blocs de pierre au moyen The present invention relates to a fixed device with vertical cutting for sawing blocks of stone by means of
d'un outil à fil de diamant.of a diamond wire tool.
Plus précisément, dans l'appareil selon l'invention, les pièces composantes sont agencées pour adapter la face aux dimensions du bloc à tailler, tout en maintenant l'outil à fil de diamant sous une tension prédéterminée, More specifically, in the apparatus according to the invention, the component parts are arranged to adapt the face to the dimensions of the block to be cut, while maintaining the diamond wire tool under a predetermined tension,
en fonction de la dureté du bloc lui-même. depending on the hardness of the block itself.
On connaît des machines pour tailler des blocs de pierre tels que du marbre ou analogues, en les fragmentant en blocs plus petits, ou en les découpant en plaques, dans lesquelles l'outil est constitué d'un fil fabriqué en acier ou autre matériau approprié, par exemple un outil à Machines are known for cutting stone blocks such as marble or the like, by fragmenting them into smaller blocks, or by cutting them into plates, in which the tool consists of a wire made of steel or other suitable material. , for example a tool to
fil de diamant.diamond wire.
Ces machines comportent généralement une structure de cadre en forme de portique sous lequel est placé le bloc à tailler, et sur lequel sont installées des poulies de guidages et autres moyens appropriés pour entraîner le fil. Dans certains cas, le groupe moteur tout entier s'abaisse avec le fil au fur et à mesure de la taille; dans d'autres cas, par exemple, selon le descriptif du brevet italien ne 20558 B/86 du même auteur, le bloc-moteur coulisse horizontalement le long de la poutre These machines generally have a frame structure in the form of a gantry under which the block to be cut is placed, and on which are installed guide pulleys and other suitable means for driving the wire. In some cases, the entire power unit is lowered with the wire as it is pruned; in other cases, for example, according to the description of Italian patent no 20558 B / 86 by the same author, the engine block slides horizontally along the beam
du cadre du portique.of the frame of the gantry.
Tous ces dispositifs connus sont nécessaires pour résoudre au moins deux problèmes: celui qui consiste à appliquer à la poulie d'entraînement - au moins en fonctionnement - un frottement suffisant, de manière à obtenir une tension assez forte du fil, et celui du guidage du fil très soigneusement, au stade initial, dans le but d'effectuer une coupe précise. De plus, les structures et mécanismes employés ne doivent pas être trop complexes, afin de ne pas peser excessivement sur les All these known devices are necessary to solve at least two problems: that which consists in applying to the drive pulley - at least in operation - sufficient friction, so as to obtain a fairly high tension of the wire, and that of guiding the wire very carefully, at the initial stage, in order to make a precise cut. In addition, the structures and mechanisms used must not be too complex, so as not to weigh excessively on the
coûts de production.production costs.
La présente invention propose un appareil capable de simplifier, encore davantage, à la fois la structure et les mécanismes qui y sont reliés tout en éliminant The present invention provides an apparatus capable of further simplifying both the structure and the mechanisms connected thereto while eliminating
complètement les problèmes mentionnés ci-dessus. completely the problems mentioned above.
Ce but est atteint grâce à une machine dans laquelle ce n'est pas l'outil, mais les blocs à tailler qui sont déplacés et avancés vers le fil, ce qui ne nécessite pas l'ajustement de la longueur du fil au fur et à mesure de This object is achieved thanks to a machine in which it is not the tool, but the blocks to be cut which are moved and advanced towards the wire, which does not require the adjustment of the length of the wire as and when measure of
l'avance de la découpe.cutting advance.
La machine selon l'invention prévoit des poulies folles fixées à un bras mobile dont la course verticale est égale ou supérieure à la variation possible de 2 0 dimensions des blocs i scier, de façon à adapter l'ouverture de l'outil à fil de diamant aux dimensions du bloc afin de guider l'outil plus précisément dans les The machine according to the invention provides idler pulleys fixed to a movable arm whose vertical stroke is equal to or greater than the possible variation of the dimensions of the blocks to be sawn, so as to adapt the opening of the tool to wire diamond to the dimensions of the block in order to guide the tool more precisely in the

Cet avantage ainsi que d'autres avantages de This and other advantages of
l'invention ressortiront de la description détaillée the invention will emerge from the detailed description
suivante, en se référant aux dessins annexés dans following, referring to the accompanying drawings in
lesquels: -which: -
la figure 1 représente une vue avant d'un appareil selon l'invention; la figure 2 représente une vue latérale de l'appareil de la figure 1; la figure 3 représente une vue en plan du même appareil. Sur un socle 1 est fixée une structure, désignée dans son ensemble par le repère numérique 2 comportant une colonne 3 à l'intérieur de laquelle se déplace un poteau téléscopique 4 ayant par exemple une section carrée, sur lequel coulisse un bras 5 supportant un groupe de poulies Figure 1 shows a front view of an apparatus according to the invention; Figure 2 shows a side view of the apparatus of Figure 1; Figure 3 shows a plan view of the same device. On a base 1 is fixed a structure, designated as a whole by the reference numeral 2 comprising a column 3 inside which a telescopic pole 4 having for example a square section, on which slides an arm 5 supporting a group pulleys

Le déplacement du poteau est actionné par des mécanismes connus, tels que des vis sans fin ou des moyens The displacement of the post is actuated by known mechanisms, such as worms or means

Sur le bras 5 sont installées des poulies folles 6, 7 et 8, la dernière étant équipée d'un dispositif de commande 9 de type connu, prévu pour aligner exactement ladite poulie folle avec la poulie folle correspondante 8' (voir figure 1) du jeu des poulies folles inférieures 6', 7' et 8' On the arm 5 are installed idler pulleys 6, 7 and 8, the latter being equipped with a control device 9 of known type, designed to exactly align said idler pulley with the corresponding idler pulley 8 '(see FIG. 1) of the set of 6 ', 7' and 8 'lower idler pulleys
montées sur un bras 5' analogue au précédent. mounted on an arm 5 'similar to the previous one.
Ce second groupe est monté au-dessous du niveau des rails fixes 10, sur lesquels sont entraînés en parallèle deux chariots 11, 11', le premier transportant le bloc 12 à couper, et le second les pièces coupées correspondantes 13. Sur le poteau 3 est montée une poulie folle 14 qui envoie l'outil à fil de diamant 15 vers la poulie folle 6, This second group is mounted below the level of the fixed rails 10, on which two carriages 11, 11 ′ are driven in parallel, the first carrying the block 12 to be cut, and the second the corresponding cut parts 13. On the post 3 a crazy pulley 14 is mounted which sends the diamond wire tool 15 to the crazy pulley 6,

Le fonctionnement se fait de la façon suivante: Lorsque le bloc 12 à tailler a été placé sur un chariot 11', il est avancé, avec le chariot 11, vers la Operation is as follows: When the block 12 to be cut has been placed on a carriage 11 ′, it is advanced, with the carriage 11, towards the
face 8-8'.8-8 'side.
La hauteur du bras supérieur 5 est ajustée jusqu'à ce qu'une faible distance soit obtenue entre la surface supérieure du bloc 12 et la partie inférieure de la poulie folle 8. De cette façon, on peut réaliser à l'origine une The height of the upper arm 5 is adjusted until a small distance is obtained between the upper surface of the block 12 and the lower part of the idler pulley 8. In this way, it is possible at the outset to
découpe plus précise.more precise cutting.
La tension du fil est ensuite ajustée, soit à la main, soit grâce à des commandes automatiques, grâce à des dispositifs déjà connus, afin d'empêcher l'outil à fil de diamant d'effectuer des décalages indésirables; les dispositifs 9 et 9' sont destinés à contrôler que la coupe réalisée est bien perpendiculaire au plan de glissement The thread tension is then adjusted, either by hand or by automatic controls, using already known devices, in order to prevent the diamond thread tool from making undesirable shifts; devices 9 and 9 'are intended to check that the cut made is indeed perpendicular to the sliding plane

Comme on peut le remarquer, l'appareil selon l'invention est considérablement simplifié par rapport à des machines analogues déjà connues. Ceci permet de réduire à la fois les coûts de production et d'exploitation, d'employer un outil à fil de diamant plus court ou, pour une longueur égale, de faire des coupes plus longues, après avoir optimisé les opérations de As can be seen, the apparatus according to the invention is considerably simplified compared to similar machines already known. This reduces both production and operating costs, employs a shorter diamond wire tool or, for an equal length, makes longer cuts, after optimizing the cutting operations.
l'outil à fil de diamant.the diamond wire tool.
De plus, les surfaces résultant de la découpe seront moins rugueuses et de meilleures qualités, la largeur de l'outil à fil de diamant ayant été réduite, en éliminant réellement les risques d'oscillation ou de déviation qui pourraient se produire pendant la coupe. Naturellement les dimensions, ainsi que les matériaux employés, peuvent varier, en fonction des différentes conditions d'utilisation. In addition, the surfaces resulting from the cutting will be less rough and of better quality, the width of the diamond wire tool having been reduced, effectively eliminating the risks of oscillation or deviation which could occur during cutting. Of course the dimensions, as well as the materials used, can vary, depending on the different conditions of use.
