Description

La présente invention est relative à une machine de fabrication de bagues d'étanchéité du type comportant une armature et un corps, notamment en élastomère, comportant au moins une lèvre d'étanchéité. The present invention relates to a machine for manufacturing sealing rings of the type comprising a frame and a body, in particular made of elastomer, comprising at least one sealing lip.

De telles bagues sont couramment utilisées, notamment dans l'industrie automobile, pour réaliser une étanchéité entre une pièce tournante, par exemple un arbre et une pièce fixe, par exemple l'alésage du carter dans lequel l'arbre est monté à rotation. Such rings are commonly used, in particular in the automobile industry, for sealing between a rotating part, for example a shaft and a fixed part, for example the bore of the casing in which the shaft is mounted for rotation.

De telles bagues sont fabriquées par moulage, puis soumises à des opérations de finition par usinage pour notamment éliminer les bavures provenant de l'opération de moulage et usiner des chanfreins. Such rings are manufactured by molding, then subjected to operations of finishing by machining in order in particular to eliminate the burrs coming from the operation of molding and to machine chamfers.

La présente invention se propose de fournir une machine intégrée permettant de réaliser les différentes opérations nécessaires à la fabrication de telles bagues d'étanchéité de manière automatique et à grande cadence sans intervention manuelle, réduisant ainsi notablement le personnel nécessaire et les temps de fabrication. The present invention proposes to provide an integrated machine making it possible to carry out the various operations necessary for the manufacture of such sealing rings automatically and at high speed without manual intervention, thus significantly reducing the personnel required and the manufacturing times.

La machine selon l'invention se caractérise essentiellement par le fait qu'elle comporte un poste de moulage comportant un dispositif de moulage, notamment par injection, un poste de refroidissement comportant au moins deux supports de bagues et au moins un dispositif de refroidissement des bagues maintenues dans lesdits supports, un poste d'usinage comportant un support rotatif, des moyens pour maintenir en position la bague sur ledit support pendant la rotation de celui-ci et un ensemble d'outils tranchants aptes à être amenés au contact de la bague maintenue sur ledit support rotatif, et un dispositif manipulateur agencé pour réaliser une succession de cycles consistant à prendre en charge une bague au poste de moulage, la transférer au poste de refroidissement sur l'un des supports de bague, prendre en charge une bague maintenue sur le ou l'un des autres supports au poste de refroidissement et la transférer au poste d'usinage. The machine according to the invention is essentially characterized by the fact that it comprises a molding station comprising a molding device, in particular by injection, a cooling station comprising at least two ring supports and at least one ring cooling device held in said supports, a machining station comprising a rotary support, means for holding the ring in position on said support during the rotation of the latter and a set of cutting tools capable of being brought into contact with the ring maintained on said rotary support, and a manipulator device arranged to carry out a succession of cycles consisting of taking charge of a ring at the molding station, transferring it to the cooling station on one of the ring supports, taking charge of a ring held on or one of the other supports at the cooling station and transfer it to the machining station.

Ainsi, dans la machine selon l'invention, ltopération de moulage d'une pièce peut s'effectuer simultanément à l'étape de refroidissement de la bague précédemment moulée et transférée au poste de refroidissement, ainsi qu'à l'étape d'usinage de la bague moulée avant cette dernière et transférée du poste de refroidissement au poste d'usinage. Thus, in the machine according to the invention, the molding operation of a part can be carried out simultaneously with the step of cooling the ring previously molded and transferred to the cooling station, as well as with the machining step. of the ring molded before the latter and transferred from the cooling station to the machining station.

Ainsi, avec un poste de refroidissement comportant deux supports de bague, trois bagues se trouvent simultanément présentes dans la machine en cours de moulage, en cours de refroidissement et respectivement en cours d'usinage, (ou en cours de transfert entre les différents postes) ce qui accroît notablement les cadences de fabrication. Thus, with a cooling station comprising two ring supports, three rings are simultaneously present in the machine during molding, during cooling and respectively during machining, (or during transfer between the different stations) which significantly increases the production rates.

Le ou les dispositifs de refroidissement de chacune des bagues maintenus sur leur support respectif au poste de refroidissement comportent avantageusement deux buses de soufflage d'un fluide de refroidissement, notamment d'air comprimé, disposées au-dessus du support correspondant et agencées pour diriger le fluide de refroidissement sur deux emplacements diamétralement opposés de la bague, ce qui, outre le refroissement de celle-ci offre l'avantage supplémentaire d'éloigner pendant le refroidissement de la bague la bavure périphérique dont est munie celle-ci du corps en élastomère, évitant tout collage de la bavure sur le corps de la bague. The cooling device (s) for each of the rings maintained on their respective support at the cooling station advantageously comprise two nozzles for blowing a cooling fluid, in particular of compressed air, disposed above the corresponding support and arranged to direct the coolant on two diametrically opposite locations of the ring, which, in addition to cooling it offers the additional advantage of removing the peripheral burr which is provided therefrom from the elastomer body during cooling of the ring, avoiding any bonding of the burr on the body of the ring.

Dans le cas de bagues moulées par injection, les bagues sortant du moule comportent outre une bavure périphérique, un voile intérieur prolongé en son centre par une carotte. In the case of rings molded by injection, the rings leaving the mold have, in addition to a peripheral burr, an inner veil extended in its center by a core.

Les opérations d'usinage consistent à éliminer la bavure périphérique, éliminer le voile intérieur et réaliser les chanfreins nécessaires. The machining operations consist in eliminating the peripheral burr, eliminating the internal veil and making the necessary chamfers.

Pour maintenir en position la bavure périphérique en vue de son tranchage au poste d'usinage, les moyens pour maintenir la bague en position sur son support au poste d'usinage comportent avantageusement deux galets coniques agissant sur la bague dans deux directions diamétralement opposées, évitant tout repliement de la bavure périphérique pendant son tranchage. To keep the peripheral burr in position for its cutting at the machining station, the means for holding the ring in position on its support at the machining station advantageously comprise two conical rollers acting on the ring in two diametrically opposite directions, avoiding any folding of the peripheral burr during its slicing.

Avantageusement, il est également prévu au poste d'usinage une buse de soufflage d'air agissant verticalement pour maintenir le voile après sa découpe et avant son évacuation qui s'effectue avantageusement par soufflage d'air. Advantageously, there is also provided at the machining station an air blowing nozzle acting vertically to maintain the web after its cutting and before its evacuation which is advantageously carried out by air blowing.

En particulier, pour les bagues de gros diamètres, l'alimentation en air pour le soufflage en vue de l'éjection du voile peut s'effectuer au travers d'un orifice ménagé dans le support rotatif de la bague au poste d'usinage. In particular, for large diameter rings, the air supply for blowing with a view to ejecting the web can be effected through an orifice made in the rotary support of the ring at the machining station.

D'autres avantages et caractéristiques de l'invention apparattront à la lecture de la description suivante d'un exemple de réalisation nullement limitatif en se référant au dessin annexé dans lequel
Les figures 1 à 3 sont des vues schématiques illustrant la machine selon l'invention selon trois positions en cours de fonctionnement.Other advantages and characteristics of the invention will appear on reading the following description of an exemplary embodiment which is in no way limitative, with reference to the appended drawing in which
Figures 1 to 3 are schematic views illustrating the machine according to the invention in three positions during operation.

La machine de fabrication de bagues d'étanchéité selon l'invention comporte quatre composants essentiels à savoir un poste de moulage désigné globalement par 10, un poste de refroidissement désigné globalement par 20, un poste d'usinage désigné globalement par 30 et un dispositif manipulateur 40. The machine for manufacturing sealing rings according to the invention comprises four essential components, namely a molding station generally designated by 10, a cooling station generally designated by 20, a machining station generally designated by 30 and a manipulator device. 40.

Le poste de moulage illustré sur le dessin est du type à injection et comporte un élément de moule fixe 11 solidaire d'un plateau de moule supérieur fixe, un élément de moule mobile 12 solidaire d'un plateau inférieur mobile et un noyau intérieur 13. The molding station illustrated in the drawing is of the injection type and comprises a fixed mold element 11 secured to a fixed upper mold plate, a movable mold element 12 secured to a movable lower plate and an inner core 13.

Le dispositif de moulage utilisé est de type bien connu et n'a pas besoin d'être décrit plus en détail. The molding device used is of a well known type and does not need to be described in more detail.

Le moule est alimenté manuellement ou de manière automatique en armatures métalliques sur lesquelles doivent être formées la ou les garnitures d'étanchéité à lèvre. Selon l'invention, on peut réaliser des bagues mono ou multimatière. The mold is supplied manually or automatically with metal reinforcements on which the lip seal (s) are to be formed. According to the invention, single or multi-material rings can be produced.

Le poste de refroidissement 20 comporte un plateau 21 mobile sur des glissières 22 et comportant sur sa face supérieure des supports de bague, au nombre de deux dans l'exemple illustré, 23 et respectivement 24. The cooling station 20 comprises a plate 21 movable on slides 22 and comprising on its upper face ring supports, 23 in number in the example illustrated, 23 and 24 respectively.

Pour le refroidissement des bagues maintenues sur leur support respectif, il est prévu au moins une paire de buses de soufflage d'air comprimé 25, 26 agencées pour diriger verticalement de haut en bas des courants d'air en des emplacements diamètralement opposés de la bague maintenue sur son support. For the cooling of the rings maintained on their respective support, at least one pair of compressed air blowing nozzles 25, 26 is provided, arranged to direct air currents vertically up and down at diametrically opposite locations of the ring. held on its support.

Le poste d'usinage 30 comporte un support rotatif de bague 31 monté sur un plateau 32 mobile en translation sur des glissières 33. The machining station 30 comprises a rotary ring support 31 mounted on a plate 32 movable in translation on slides 33.

Au poste d'usinage 30, il est prévu un ensemble d'outils tranchants 34 destinés à sectionner les bavures sur la bague disposée sur le support tournant 31r notamment la bavure périphérique extérieure et le voile intérieur comportant la carotte. Les outils tranchants agissent à cet effet respectivement sur un diamètre extérieur et sur un diamètre intérieur de la bague et réalisent également les chanfreins désirés sur ces diamètres. At the machining station 30, there is provided a set of cutting tools 34 intended to cut the burrs on the ring disposed on the rotating support 31r, in particular the outer peripheral burr and the inner veil comprising the core. The cutting tools act for this purpose respectively on an outside diameter and on an inside diameter of the ring and also produce the desired chamfers on these diameters.

Pour maintenir la bague en position sur le support 31 pendant la rotation de celui-ci, il est prévu deux galets coniques 35 agissant sur la bague dans deux directions diamètralement opposées. To keep the ring in position on the support 31 during the rotation of the latter, there are provided two conical rollers 35 acting on the ring in two diametrically opposite directions.

Pour évacuer le voile tranché, il est prévu un mécanisme de soufflage d'air au travers du support 31 par l'intermédiaire d'une buse de soufflage 36 (figure 3). To evacuate the cut veil, an air blowing mechanism is provided through the support 31 by means of a blowing nozzle 36 (FIG. 3).

Le dispositif manipulateur comporte des doigts formant pince d'extrémité 41 montée à l'extrémité d'un bras télescopique 42, le bras 42 étant lui-même agencé pour pouvoir tourner autour d'un axe vertical 43. The manipulator device comprises fingers forming an end clamp 41 mounted at the end of a telescopic arm 42, the arm 42 itself being arranged so as to be able to rotate about a vertical axis 43.

On va maintenant décrire sommairement le fonctionnement de la machine selon l'invention. We will now briefly describe the operation of the machine according to the invention.

Dans la position de la figure 1, le moule au poste de moulage 10 vient d'être ouvert et le dispositif manipulateur 40 vient de prendre en charge, par sa pince d'extrémité 41, une bague B1, cette dernière se trouvant alors à une température de l'ordre de 200 C.  In the position of FIG. 1, the mold at the molding station 10 has just been opened and the manipulator device 40 has just taken over, by its end clamp 41, a ring B1, the latter then being at a temperature of the order of 200 C.

Dans cette position, une seconde bague B2 précédemment obtenue et transferée par le dispositif manipulateur 40 se trouve en cours de refroidissement sur le support 23 du poste de refroidissement 20. In this position, a second ring B2 previously obtained and transferred by the manipulator device 40 is being cooled on the support 23 of the cooling station 20.

Selon l'invention, le cycle de la machine est déterminé pour assurer un temps de refroidissement suffisant pour amener la bague à une température voisine de 300 à laquelle l'usinage peut se faire dans de bonnes conditions. According to the invention, the machine cycle is determined to ensure sufficient cooling time to bring the ring to a temperature close to 300 at which the machining can be carried out under good conditions.

Une troisième bague B3 obtenue antérieurement à la bague B2 est transferée au poste d'usinage 30. A third ring B3 obtained before the ring B2 is transferred to the machining station 30.

Le dispositif manipulateur 40 après avoir transferé la bague
B1 sur le support 24 comme schématisé par la flèche de la figure 2 vient prendre en charge la bague B2 à la fin de son refroidissement sur le support 23 et, comme schématisé par la flèche sur la figure 3, la transfère sur le support de bague 35 du poste d'usinage.The manipulator device 40 after having transferred the ring
B1 on the support 24 as shown diagrammatically by the arrow in FIG. 2 supports the ring B2 at the end of its cooling on the support 23 and, as shown diagrammatically by the arrow in FIG. 3, transfers it to the ring support 35 of the machining station.

La bague est recue du poste d'usinage sur le plateau 32 en position avancée. Le plateau est ensuite amené à reculer pour amener la bague en prise avec les galets 35 et au contact des outils de tranchage 34. The ring is received from the machining station on the plate 32 in the advanced position. The plate is then brought back to bring the ring into engagement with the rollers 35 and in contact with the slicing tools 34.

Comme on le voit sur la figure 3, pendant l'usinage de la bague B2, le moule au poste de moulage 10 est fermé pour la fabrication d'une nouvelle bague. As can be seen in FIG. 3, during the machining of the ring B2, the mold at the molding station 10 is closed for the manufacture of a new ring.

Du fait que la machine selon l'invention permet de réaliser simultanément différentes étapes de fabrication d'une bague d'étanchéité, les cadences de production sont notablement accrues, la machine selon l'invention permettant ainsi la fabrication d'une bague toutes les treize secondes environ. Because the machine according to the invention makes it possible to simultaneously carry out different stages of manufacturing a sealing ring, the production rates are significantly increased, the machine according to the invention thus making it possible to manufacture a ring every thirteen about seconds.

Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'on peut lui apporter diverses variantes et modifications sans pour autant sortir ni de son cadre, ni de son esprit.  Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it can be brought to various variants and modifications without departing from its scope, nor of his mind.
