Abstract

The equipment clamps in position a saw blade whose central portion comprises two steel cores spaced apart, and between which coolant is delivered. The cores (6,7) are gripped between two flanged bodies, one of which also forms the coolant inlet passage (9a). There can be a mounting flange (3) secured against the face of the machine flange (1) by a clamping screw (2), while a clamping ring (4) is in turn attached to the mounting flange, the cores being gripped between the mounting flange and the ring. Clamping devices (8) clear of the ring secure the mounting flange to the machine flange.

Description

La présente invention a pour objet un dispositif de fixation de lames de scies, dont la partie médiane est composée de deux noyaux en acier distancés l'un par rapport à l'autre, de façon à constituer un espace creux. The subject of the present invention is a device for fixing saw blades, the middle part of which is composed of two steel cores spaced apart from one another, so as to constitute a hollow space.

Il existe déjà des moyens de fixation des lames de scies contre la bride de la machine, mais le but de l'invention consiste à développer et perfectionner les moyens connus de ce genre de montage des lames, de telle manière qu'il soit possible d'introduire dans l'interstice entre les noyaux d'acier un liquide réfrigérant, réalisation atteinte en encastrant les noyaux d'acier entre deux brides, dont l'une est façonnée de manière à comporter un canal annulaire destiné à amener le liquide réfrigérant en question. There are already means for fixing the saw blades against the machine flange, but the object of the invention is to develop and improve the known means of this type of mounting of the blades, in such a way that it is possible to '' introduce a coolant into the gap between the steel cores, an achievement achieved by embedding the steel cores between two flanges, one of which is shaped so as to have an annular channel intended to bring the coolant in question .

Plus particulièrement, le nouveau dispositif est caractérisé par une bride rapportée, se fixant au moyen d'une vis de serrage sur la partie frontale de la bride de la machine. Cette bride rapportée constitue l'un des éléments de l'ensemble obtenu conjointement avec une bride annulaire de fixation placée devant elle, et formant l'autre élément entre lesquels sont encastrés les noyaux en acier. Font également partie de l'invention, les moyens de serrage de la bride rapportée contre celle de la machine, tout en ayant soin que ces moyens soient distancés de la bride de serrage annulaire. More particularly, the new device is characterized by an attached flange, which is fixed by means of a clamping screw on the front part of the machine flange. This attached flange constitutes one of the elements of the assembly obtained jointly with an annular fixing flange placed in front of it, and forming the other element between which the steel cores are embedded. Also part of the invention, the clamping means of the attached flange against that of the machine, while taking care that these means are distant from the annular clamping flange.

Grâce à cet interstice entre ces moyens de serrage et la forme annulaire de l'un d'entre eux, il est réalisé un accès pour l'introduction du liquide réfrigérant dans le creux existant entre les noyaux en acier. Thanks to this gap between these clamping means and the annular shape of one of them, an access is made for the introduction of the coolant into the hollow existing between the steel cores.

D'une façon particulièrement avantageuse, la bride annulaire possède une retombée biaise par rapport à son axe, créant ainsi une entrée annulaire conique favorisant l'arrivée du liquide réfrigérant. In a particularly advantageous manner, the annular flange has a biased drop with respect to its axis, thus creating a conical annular inlet promoting the arrival of the coolant.

Les organes de fixation comprennent un anneau intermédiaire et un écrou placés sur la vis de fixation de la bride de la machine. The fasteners include an intermediate ring and a nut placed on the machine flange fixing screw.

Le dessin annexé représente à titre d'exemple non limitatif, une forme d'exécution en coupe du dispositif. The appended drawing represents by way of nonlimiting example, an embodiment in section of the device.

La bride de la machine désignée par 1, comporte la vis 2. The machine flange designated by 1, includes screw 2.

Frontalement sur la bride 1, est montée la bride rapportée 3, constituant l'un des éléments du dispositif préconisé. Sur la face frontale de la bride 57 est montée une bride 4, constituant l'autre élément de ce dispositif. Entre ces deux éléments sont encastrés les noyaux en acier 6 et 7 de la lame de scie à fixer, l'écartement à prévoir étant obtenu par des pièces intercalaires.Frontally on the flange 1, the attached flange 3 is mounted, constituting one of the elements of the recommended device. On the front face of the flange 57 is mounted a flange 4, constituting the other element of this device. Between these two elements are embedded the steel cores 6 and 7 of the saw blade to be fixed, the spacing to be provided being obtained by intermediate pieces.

L'assemblage des brides 3 et 4 est obtenu par des vis usuelles 5. The assembly of the flanges 3 and 4 is obtained by usual screws 5.

Les moyens de fixation de la bride rapportée 3 à celle de la machine 1 sont, dans leur ensemble, désignés par su Il est respecté une zone libre 9 qui détermine un canal d'accès 9a pour le liquide réfrigérant vers le creux 13,entre les noyaux en acier 6 et 7. La bride d'encastrement 4 accuse avantageusement une retombée biaise 12 par rapport à son axe, créant ainsi une ouverture conique pour l'arrivée du liquide réfrigérant. The means for fixing the attached flange 3 to that of the machine 1 are, as a whole, designated by su There is a free zone 9 which determines an access channel 9a for the coolant to the hollow 13, between the steel cores 6 and 7. The embedding flange 4 advantageously exhibits a bias drop 12 relative to its axis, thus creating a conical opening for the arrival of the coolant.

La bride rapportée 3 est fixée au moyen d'un anneau intermédiaire 10, maintenu lui-même par l'écrou 11 de la vis 2. The attached flange 3 is fixed by means of an intermediate ring 10, itself held by the nut 11 of the screw 2.

Le refroidissement de la lame de scie a lieu d'une manière particulièrement favorable du fait qu'elle agit comme une pompe centrifuge, le liquide réfrigérant étant amené axialement et évacué radialement. The cooling of the saw blade takes place in a particularly favorable manner because it acts like a centrifugal pump, the coolant being brought in axially and discharged radially.

Les lames de scies entrant en ligne de compte ne servent pas uniquement à débiter des matières pierreuses (pierres naturelles),mais aussi à sectionner des pièces préfabriquées en béton, fribro-ciment et autres, ainsi que des éléments pour le revêtement des chaussées.  The saw blades involved are not only used for cutting stony materials (natural stones), but also for cutting prefabricated concrete, fribro-cement and other parts, as well as elements for paving pavements.
