Description

Dispositif pour le recuit partiel de pièces mécaniques usinées Device for the partial annealing of machined mechanical parts
La présente invention a pour objet un dispositif pour le recuit partiel de pièces mécaniques usinées. Les dispositifs actuels pour le recuit de pièces sont lents et imprécis car le chauffage s'effectue par induction et, une fois la pièce chauffée, il s'écoule un laps de temps important avant son refroidissement, de sorte que la chaleur de la partie chauffée, à recuire, s'étend par conduction à des parties de la pièce ne devant pas être recuites.The present invention relates to a device for the partial annealing of machined mechanical parts. Current devices for annealing parts are slow and imprecise because the heating takes place by induction and, once the part is heated, a significant period of time elapses before it cools, so that the heat of the heated part , to be annealed, extends by conduction to parts of the part which should not be annealed.
Le but de la présente invention est de permettre une augmentation du nombre de pièces traitées par unité de temps et surtout d'obtenir une plus grande précision en évitant que des parties de la pièce ne devant pas être recuites ne soient chauffées.The object of the present invention is to allow an increase in the number of parts treated per unit of time and above all to obtain greater precision by preventing parts of the part which do not have to be annealed from being heated.
Le dispositif objet de l'invention pour le recuit partiel de pièces mécaniques usinées tend à obvier aux inconvénients des dispositifs à chauffage à induction existants et à permettre une plus grande précision du traitement ainsi qu'une augmentation de la vitesse et de la cadence de traitement des pièces. Ce dispositif est caractérisé par les caractéristiques énumérées à la revendication 1.The device which is the subject of the invention for the partial annealing of machined mechanical parts tends to obviate the drawbacks of existing induction heating devices and to allow greater treatment precision as well as an increase in the speed and rate of treatment. pieces. This device is characterized by the characteristics listed in claim 1.
Le dessin annexé illustre schématiquement et à titre d'exemple une formé d'exécution du dispositif pour le recuit partiel de pièces mécaniques usinées. La figure 1 est une vue en perspective partielle du dispositif.The attached drawing illustrates schematically and by way of example an embodiment of the device for the partial annealing of machined mechanical parts. Figure 1 is a partial perspective view of the device.
La figure 2 illustre une pièce mécanique devant être traitée par le dispositif.Figure 2 illustrates a mechanical part to be treated by the device.
Dans l'application représentée du dispositif pour le traitement de pièces usinées celui-ci est utilisé pour le recuit partiel de broches de connecteurs électriques. Bien entendu, ce dispositif pourrait être adapté pour traiter d'autres pièces mécaniques présentant d'autres formes.In the illustrated application of the device for the treatment of machined parts, it is used for the partial annealing of pins of electrical connectors. Of course, this device could be adapted to treat other mechanical parts having other shapes.
Le dispositif pour le recuit partiel de pièces mécaniques usinées comporte un bac de refroidissement 1 partiellement rempli d'eau. Cette eau est maintenue à une température basse d'environ 12 à 15°C soit par un apport constant d'eau froide et une évacuation, soit par un système de réfrigération en circuit fermé de l'eau contenue dans le bac 1 .The device for the partial annealing of machined mechanical parts comprises a cooling tank 1 partially filled with water. This water is kept at a low temperature of around 12 to 15 ° C or by a constant supply of water cold and an evacuation, either by a closed circuit refrigeration system of the water contained in the tank 1.
Ce dispositif comporte encore une roue porte pièces 2, de préférence en aluminium, entraînée en rotation par un axe horizontal 3, la roue 2 s'etendant ainsi dans un plan vertical. Cette roue est partiellement immergée dans l'eau contenue dans le bac 1. L'axe 3 de la roue est complètement immergé dans le bac 1. Le passage dudit axe 3 est étanchéisé par un joint solidaire du bac 1.This device also comprises a parts-carrying wheel 2, preferably made of aluminum, driven in rotation by a horizontal axis 3, the wheel 2 thus extending in a vertical plane. This wheel is partially immersed in the water contained in the tank 1. The axis 3 of the wheel is completely submerged in the tank 1. The passage of said axis 3 is sealed by a joint integral with the tank 1.
Dans l'application décrite les pièces à recuire partiellement sont des broches 4 de contacteurs électriques, comme illustré à la figure 2. Ces broches 4 ne doivent être recuites que dans leur partie avant 5, le reste de la pièce ne devant pas être traité thermiquement.In the application described, the parts to be partially annealed are pins 4 of electrical contactors, as illustrated in FIG. 2. These pins 4 must only be annealed in their front part 5, the rest of the part not having to be heat treated .
La périphérie de la roue 2 est munie de perçages radiaux 6 faisant office de posage pour les pièces 4. La roue 2 comporte ainsi un grand nombre de posages, de l'ordre de 30 à 60 par exemple, recevant chacun une pièce à traiter 4. La roue 2 qui plonge verticalement dans le bac 1 est entraînée par un moteur pas à pas ou une table tournante pneumatique en bout d'arbre contrôlée par un automate programmable permettant de déterminer le temps d'arrêt du moteur ou de la table tournante entre deux pas d'indexation, ainsi que la vitesse de passage d'une position d'indexation à la suivante. Le dispositif comporte encore un dispositif d'alimentation des pièces à traiter, manuel ou automatique, permettant de placer pendant un temps d'arrêt de la roue 2 une pièce dans un de ses perçages 6. La pièce 4 est placée dans la roue de manière à ce que la partie devant être recuite 5 émerge hors de la périphérie de la roue, tandis que la partie de la pièce 4 ne devant pas être recuite est située à l'intérieur d'un perçage 6 de cette roue 2. Il est évident que la forme des posages 6 et leur profondeur dépendent de la forme de la partie ne devant pas être recuite des pièces 4 à traiter.The periphery of the wheel 2 is provided with radial bores 6 serving as a fitting for the parts 4. The wheel 2 thus comprises a large number of fittings, of the order of 30 to 60 for example, each receiving a part to be treated 4 The wheel 2 which plunges vertically into the tank 1 is driven by a stepping motor or a pneumatic rotary table at the end of the shaft controlled by a programmable automaton making it possible to determine the downtime of the motor or the rotary table between two indexing steps, as well as the speed of passage from one indexing position to the next. The device also includes a device for feeding the parts to be treated, manual or automatic, making it possible to place a part in one of its bores 6 during a downtime of the wheel 2. The part 4 is placed in the wheel so that the part to be annealed 5 emerges from the periphery of the wheel, while the part of the part 4 not to be annealed is located inside a bore 6 of this wheel 2. It is obvious that the shape of the layings 6 and their depth depend on the shape of the part not to be annealed from the pieces 4 to be treated.
Le dispositif pour le recuit partiel de pièces mécaniques comporte encore un chalumeau 7 dont la flamme est dirigée sur la pièce à recuire 5 située juste en _> dessus du niveau d'eau de la cuve 1. Ce chalumeau 7 fonctionne en permanence et chauffe une pièce 5 portée par la roue 2 pendant le temps d'arrêt de cette roue. Suivant la durée du temps d'arrêt de la roue, durée qui est réglable et programmable, on peut ajuster, pour une température et un positionnement de la flamme donnés, la température de recuit de la partie 5 de la pièce à traiter. Lors de chaque indexage de la roue 2 la pièce chauffée est immédiatement plongée dans l'eau du bac 1. Le temps d'indexage étant très court, la partie 5 à recuire de la pièce 4 n'a pas le temps de se refroidir, de sorte que le recuit peut être fait avec grande précision. De plus, l'inertie thermique de la roue 2 étant grande et sa température maintenue constante par le bain d'eau, la partie de la pièce 4 ne devant pas être recuite est maintenue à basse température puisqu'elle est en contact avec cette roue 2 dans son posage 6. La diffusion de chaleur de la partie chauffée 5 de la pièce dans le reste de la pièce est empêchée par son contact avec la roue 2. Au fur et à mesure des pas successifs de la roue 2 les pièces recuites sont entraînées par la roue 2 jusqu'au moment où, proches de la verticale, elles tombent par gravité dans un récipient placé au fond du bac 1 permettant leur récupération.The device for the partial annealing of mechanical parts also comprises a torch 7, the flame of which is directed onto the part to be annealed 5 located just in _> above the water level in the tank 1. This torch 7 operates continuously and heats a part 5 carried by the wheel 2 during the stop time of this wheel. Depending on the duration of the wheel stopping time, which is adjustable and programmable, it is possible to adjust, for a given flame temperature and positioning, the annealing temperature of part 5 of the part to be treated. During each indexing of the wheel 2 the heated part is immediately immersed in the water of the tank 1. The indexing time being very short, the part 5 to be annealed of the part 4 does not have time to cool, so that annealing can be done with great precision. In addition, the thermal inertia of the wheel 2 being large and its temperature kept constant by the water bath, the part of the part 4 which does not have to be annealed is kept at low temperature since it is in contact with this wheel. 2 in its fitting 6. The heat diffusion from the heated part 5 of the part into the rest of the part is prevented by its contact with the wheel 2. As successive steps of the wheel 2 the annealed parts are driven by the wheel 2 until, close to the vertical, they fall by gravity into a container placed at the bottom of the tank 1 allowing their recovery.
Dans l'exemple illustré le dispositif pour le recuit comporte un dispositif d'arrivée automatique des pièces à traiter dans les posages 6 de la roue 2. Les pièces 4 sont amenées une à une par un tuyau 8 sur la périphérie de la roue 2 et tombent dans les posages 6 successifs. Une lame ressort 9 assure que la ou les pièces 4 situées avant celle exposée à la flamme du chalumeau 7 sont positionnées correctement dans leurs posages 6. Dans l'exemple illustré le dispositif pour le recuit de pièces comporte encore des moyens de nettoyage de la périphérie de la roue entre le dispositif d'arrivée 8 des pièces et la flamme du chalumeau 7. Ce dispositif est formé par une buse 10 alimentée en air comprimé. Comme le chauffage de la partie 5 de la pièce à traiter est très rapide, de l'ordre de quelques dixièmes de seconde, que le nombre de posages 6 est grand, de l'ordre de 30 à 60, on peut arriver avec ce dispositif à traiter 60 à 80 pièces à la minute. Le dispositif décrit permet donc bien de réaliser une grande productivité tout en garantissant une précision jusqu'ici inégalée dans le recuit. Ceci est dû à l'utilisation d'une roue support 2 disposée dans un plan vertical et trempant dans l'eau du bac 1 et au fait que la pièce chauffée est à fleur de la surface de l'eau du bac et peut y être plongée en un seul pas d'indexage de la roue. En plus l'inertie thermique de la roue est grande, de sorte qu'elle reste pratiquement à la température de l'eau du bac 1 et la partie de la pièce 4 ne devant pas être traitée est en contact intime avec cette roue pendant le chauffage de sa partie à traiter, évitant ainsi toute élévation de température de la partie de cette pièce ne devant pas être recuite. In the example illustrated, the device for annealing comprises a device for automatically arriving the parts to be treated in the positions 6 of the wheel 2. The parts 4 are brought one by one by a pipe 8 to the periphery of the wheel 2 and fall in successive 6 poses. A leaf spring 9 ensures that the part or parts 4 situated before that exposed to the flame of the torch 7 are correctly positioned in their positions 6. In the example illustrated, the device for annealing parts also includes means for cleaning the periphery of the wheel between the arrival device 8 of the parts and the flame of the torch 7. This device is formed by a nozzle 10 supplied with compressed air. As the heating of part 5 of the part to be treated is very rapid, of the order of a few tenths of a second, that the number of layings 6 is large, of the order of 30 to 60, it is possible to arrive with this device to treat 60 to 80 pieces per minute. The device described therefore makes it possible to achieve high productivity while guaranteeing a precision hitherto unequaled in annealing. This is due to the use of a support wheel 2 arranged in a vertical plane and dipping in the water of the tank 1 and to the fact that the heated part is flush with the surface of the water in the tank and can be there dive in a single wheel indexing step. In addition, the thermal inertia of the wheel is large, so that it remains practically at the temperature of the water in tank 1 and the part of the part 4 which must not be treated is in intimate contact with this wheel during the heating of its part to be treated, thus avoiding any rise in temperature of the part of this part which must not be annealed.
