Abstract
Description
L'invention a pour objet un système de tension apporté sur des machines outils à débiter des blocs de pierres, marbres et granits en tranches à l'aide d'un câble diamanté. The subject of the invention is a tensioning system provided on machine tools for cutting blocks of stones, marbles and granites in slices using a diamond cable.
Pour les machines outils à câble diamanté servant à débiter les blocs en tranches, la longueur du câble sur ces machines à grands volants de sciage est de 40 m. For machine tools with a diamond cable used to cut blocks into slices, the cable length on these machines with large saw blades is 40 m.
L'encombrement total d'une telle machine est de 20 m.The total size of such a machine is 20 m.
environ. le terrain se situant entre la machine et le tendeur est inutilisable, en raison du passage du câble.about. the ground between the machine and the tensioner is unusable, due to the passage of the cable.
Cette machine ne pouvant pas être installée en atelier, elle engendre souVent la construction d'un hangar pour son installation. Since this machine cannot be installed in the workshop, it often results in the construction of a hangar for its installation.
Des machines comportant plusieurs câbles diamantés sont également connues, le tendeur est plus important, mais les mêmes problèmes d'encombrement sont rencontrés. Machines comprising several diamond cables are also known, the tensioner is more important, but the same dimensions problems are encountered.
Le but de la présente invention est de remèdier aux inconvénients précités en réalisant une machine outil de sciage en circuit court avec tendeur incorporé pour sciage au câble diamanté. il en résulte un gain de place, mais surtout une baisse de prix d'achat pour le client de l'outil de coupe à monter sur la machine. The object of the present invention is to remedy the aforementioned drawbacks by producing a short circuit sawing machine tool with incorporated tensioner for sawing with diamond wire. this results in space savings, but above all a reduction in the purchase price for the customer of the cutting tool to be mounted on the machine.
L'objet de l'invention est d'adapter un système de tension sur l'un des coulisseaux composant la machine outil de sciage. Durant le sciage, le câble décrit un certain arc de cercle appelé flêche dans le bloc de pierre, marbre ou granit à débiter. La formation de cet arc de cercle occasionne une diminution de la valeur de l'entraxe entre les deux grands volants de sciage (~ 1 600 m/m et plus). Il est donc nécessaire d'avoir un déplacement horizontal, ou tangent à un arc de cercle de la poulie de sciage pour compenser cette variation d'entraxe. The object of the invention is to adapt a tension system on one of the sliders making up the sawing machine tool. During sawing, the cable describes a certain arc of a circle called an arrow in the block of stone, marble or granite to be cut. The formation of this circular arc causes a decrease in the value of the distance between the two large saw wheels (~ 1,600 m / m and more). It is therefore necessary to have a horizontal displacement, or tangent to an arc of a circle of the saw pulley to compensate for this variation in center distance.
Le dit tendeur, monté à pivotement autour d'un axe horizontal est symétrique par rapport à un plan vertical perpendiculaire au dit axe horizontal. Said tensioner, pivotally mounted about a horizontal axis is symmetrical with respect to a vertical plane perpendicular to said horizontal axis.
Le dit tendeur est apte à supporter un fourreau étanche, porte-poulie et un effort de tension et d'amortissement d'ordre mécanique par ressort ou de technique pneumatique ou hydraulique par un vérin. Said tensioner is capable of supporting a sealed sheath, pulley holder and a tensioning and damping effort of a mechanical order by spring or of pneumatic or hydraulic technique by a jack.

La fig. 4 est une vue de droite de la fig. 3. Fig. 4 is a view from the right of FIG. 3.
La fig. 5 est une variante de réalisation de l'objet de l'invention. Fig. 5 is an alternative embodiment of the object of the invention.
Sur toutes ces figures, des éléments identiques ou analogues sont désignés par les mêmes chiffres de référence. In all these figures, identical or analogous elements are designated by the same reference numbers.
le système de tension, représenté sur la machine en phase de travail sur la fig. 1 se compose d'un bras de levier, formé de profils métalliques 2, 3, 4 & 5. Ces profils sont assemblés au moyen de deux fers plats 6 & 7 et renforcés par des profils métalliques 8. the tension system, shown on the machine in the working phase in fig. 1 consists of a lever arm, formed of metal profiles 2, 3, 4 & 5. These profiles are assembled by means of two flat bars 6 & 7 and reinforced by metal profiles 8.
Le dit bras de levier est associé à un fourreau 9 sur sa partie inférieure , monté sur roulements à billes, l'axe de ce fourreau est assemblé sur le coulisseau 1 au moyen de deux paliers 10, le dit bras de devier peut donc ainsi pivoter autour d'un axe horizontal BB. Said lever arm is associated with a sleeve 9 on its lower part, mounted on ball bearings, the axis of this sleeve is assembled on the slide 1 by means of two bearings 10, the said deviating arm can thus pivot around a horizontal axis BB.
Un système à vis et contre-écrou permet de comprimer le ressort 11, afin d'obtenir la tension voulue du câble diamanté suivant la valeur de compression du dit ressort. A screw and lock nut system makes it possible to compress the spring 11, in order to obtain the desired tension of the diamond cable according to the compression value of said spring.
Ce ressort est porté par un tube cylindrique 12, lui-même monté sur une vis 14. L'effort de tension est ainsi obtenu en comprimant à l'aide d'un écrou 13, le ressort sur l'axe de tension 17. un autre écrou derrière l'écrou 13 fait office de contre-écrou pour palier à une décompression de ressort, en raison des vibrations. This spring is carried by a cylindrical tube 12, itself mounted on a screw 14. The tension force is thus obtained by compressing, using a nut 13, the spring on the tension axis 17. a another nut behind the nut 13 acts as a lock nut to compensate for a spring decompression, due to vibrations.
Le dit axe de tension 17 est percé pour permettre le passage de la vis 14, un écrou 18 est monté en opposition au ressort pour permettre le relevage du bras de levier, pour changer le câble par exemple. Said tension pin 17 is drilled to allow the passage of the screw 14, a nut 18 is mounted in opposition to the spring to allow the lever arm to be raised, for example to change the cable.
Le dit axe de tension 17 est lui-même porté par deux paliers 19 en ses deux extrêmités, les deux paliers 19 étant solidaires des profils 4 & 5. Said tension axis 17 is itself carried by two bearings 19 at its two ends, the two bearings 19 being integral with the profiles 4 & 5.
La liaison entre la vis 14 et le coulisseau 1 s'effectue au moyen d'une chape 15 et un axe d'articulation 16. The connection between the screw 14 and the slide 1 is effected by means of a yoke 15 and a hinge pin 16.
La dite chape 15 est soudée en extrêmité de la vis 14, et peut osciller sur l'axe 16, solidaire du coulisseau 1 au moyen de cornières 20. Said yoke 15 is welded at the end of the screw 14, and can oscillate on the axis 16, integral with the slide 1 by means of angles 20.
Un des avantages importants fournis par l'inven- tion réside dans le fait qu'elle allie la simplicité et la facilité d'opération des machines outils à câble diamanté. One of the important advantages provided by the invention lies in the fact that it combines the simplicity and ease of operation of machine tools with diamond wire.
En effet, il n'est plus besoin d'aller vérifier si le câble est bien tendu grâce à ces contrepoids en pierre. In fact, there is no longer any need to go and check whether the cable is properly tensioned thanks to these stone counterweights.
Un autre avantage très important est que l'inven- tion réduit considérablement l'encombrement de la machine outil dans un atelier. Another very important advantage is that the invention considerably reduces the size of the machine tool in a workshop.
Nous pouvons également connaitre constament la valeur de tension des brins du câble à l'aide d'un tableau de lecture suivant l'allongement du ressort. We can also constantly know the tension value of the cable strands using a reading table according to the elongation of the spring.
Un autre avantage de l'invention est que l'on peut régler la tension du câble en fonction de la. vitesse de descente des coulisseaux grâce à des abaques pour utiliser le câble aux maximums de ses possibilités. Another advantage of the invention is that the tension of the cable can be adjusted according to the. speed of descent of the slides thanks to charts to use the cable to the maximum of its possibilities.
Il en ressort également que le système ressort vis écrou peut être remplacé par un vérin pneumatique ou hydraulique selon les désirs du client (ou suivant la dureté des matériaux à débiter). It also appears that the screw nut spring system can be replaced by a pneumatic or hydraulic cylinder according to the customer's wishes (or according to the hardness of the materials to be cut).
