Description

La présente invention se rapporte au soudage d'accessoires métalliques, tels que des appareils de prise de mesures, des attaches de calorifuge, des ailettes de refroidissement, sur une autre pièce métallique de beaucoup plus grandes dimensions, telle qu'une virole chaudronnée par exemple. The present invention relates to the welding of metal accessories, such as measuring devices, heat-insulating clips, cooling fins, on another metal part of much larger dimensions, such as a sheet metal shell for example. .

La fragilité des liaisons de materiaux hétérogènes realisees par fusion rend obligatoire l'utilisation de techniques particulières lors de leur exécution. L'une des techniques les plus couramment employées au chaudronnerie consiste à interposer une couche de matériau compatible avec l'un et l'autre des matériaux à assembler. Ce procédé, dit du "beurrage" permet de rapporter, en général par soudage, le matériau-tampon sur l'une ou l'autre des faces à assembler et d'effectuer le soudage entre cette face et la seconde pièce. The fragility of the links of heterogeneous materials made by fusion makes the use of particular techniques compulsory during their execution. One of the techniques most commonly used in boilermaking is to interpose a layer of material compatible with both of the materials to be joined. This process, known as "buttering" makes it possible to add, in general by welding, the buffer material on one or the other of the faces to be assembled and to carry out the welding between this face and the second part.

Dans le cas où l'on désire réaliser la liaison d'une petite pièce, de forme généralement cylindrique, tel qu'un goujon d'attache de calorifuge, sur une pièce de beaucoup plus grandes dimensions, telle qu'une virole chaudronnée pour appareil à pression, qui peut être considérée comme plate là ou l'on effectue cette soudure, il est nécessaire avec ce procédé connu de faire le tour de la petite pièce, ce qui prend beaucoup de temps et rend le procédé coûteux, d'autant plus que ces petites pièces (par exemple des goujons) doivent souvent être soudées en assez grand nombre sur la virole. In the case where it is desired to make the connection of a small part, generally cylindrical in shape, such as a heat-insulating attachment stud, to a part of much larger dimensions, such as a sheet metal ferrule for an appliance pressure, which can be considered flat where this welding is carried out, it is necessary with this known process to go around the small part, which takes a long time and makes the process expensive, all the more that these small parts (for example studs) often have to be welded in large enough numbers on the ferrule.

Grâce au procédé de l'invention, il est possible de fixer de tels accessoires en un temps beaucoup plus court, donc avec un moindre coût. Le procede de l'invention est caractérisé en ce que l'on utilise, pour fixer lesdits accessoires, la méthode dite du soudage par friction, en positionnant dans l'espace un ensemble de mise en rotation et de translation axiale d'une machine traditionnelle de soudage par friction, de manière à déplacer ledit ensemble afin qu'il soit orthogonal à la surface de la pièce metallique de grandes dimensions. Thanks to the method of the invention, it is possible to fix such accessories in a much shorter time, therefore with a lower cost. The method of the invention is characterized in that one uses, to fix said accessories, the method known as friction welding, by positioning in space a set of rotation and axial translation of a traditional machine friction welding, so as to move said assembly so that it is orthogonal to the surface of the large metal part.

L'invention concerne également un dispositif de mise en oeuvre de ce procédé caracterisé en ce qu'il comporte entre autres un bras horizontal sur lequel peut coulisser ledit ensemble. The invention also relates to a device for implementing this method characterized in that it comprises inter alia a horizontal arm on which said assembly can slide.

L'invention sera mieux comprise à l'aide de la description suivante d'un exemple de réalisation, en référence à la figure unique annexée représentant schématiquement une machine de soudage d'accessoires conforme à l'invention. The invention will be better understood with the aid of the following description of an exemplary embodiment, with reference to the appended single figure schematically showing an accessory welding machine according to the invention.

Sur la figure, la référence 1 désigne une virole chaudronnée sur la face interne de laquelle on désire fixer un grand nombre de goujons 2 destinés à l'attache d'un calorifuge. Conformément à l'invention, la fixation de ces goujons est effectuée à l'aide d'une unité de soudage par friction 6 pouvant se positionner dans l'espace grâce à la machine représentée.Cette dernière comporte
- un socle ou bâti 5,
- une colonne latérale 4 sur laquelle est fixé un moteur-frein 7 de commande de rotation d'une vis 8 de montée et descente d'un coulisseau 9 associé à une glissière 10 et portant un bras horizontal 3 lui-même soutenu à son autre extrémité à l'aide d'axes 25 et 26 et d'un tirant il qui peut être escamoté par rotation vers la gauche sous l'action d'un vérin de poussée 12,
- l'unité de soudage par friction 6 composée d'un ensemble de mise en rotation et de translation axiale d'une machine traditionnelle, montée sur le bras 3 de manière à pouvoir coulisser tout le long de celui-ci à l'aide du moteur 13 et comportant, de manière connue en soi, un mandrin 16 de fixation du goujon 2, un corps 32 d'axe vertical, une courroie d'entrainement 14, un embrayage 15, un moteur de broche 17, un vérin de poussée 20, un coulisseau 18 et une glissière 19.In the figure, the reference 1 designates a sheet metal shell on the internal face of which it is desired to fix a large number of studs 2 intended for the attachment of an insulating material. According to the invention, the fixing of these studs is carried out using a friction welding unit 6 which can be positioned in space using the machine shown.
- a base or frame 5,
- A lateral column 4 on which is fixed a brake motor 7 for controlling the rotation of a screw 8 for raising and lowering a slide 9 associated with a slide 10 and carrying a horizontal arm 3 itself supported at its other end using pins 25 and 26 and a tie rod which can be retracted by rotation to the left under the action of a thrust cylinder 12,
- the friction welding unit 6 composed of a set for rotating and axial translation of a traditional machine, mounted on the arm 3 so as to be able to slide along it using the motor 13 and comprising, in a manner known per se, a mandrel 16 for fixing the stud 2, a body 32 with a vertical axis, a drive belt 14, a clutch 15, a spindle motor 17, a thrust cylinder 20 , a slide 18 and a slide 19.

La virole 1 repose horizontalement sur le socle 5 par l'intermédiaire de galets 21 et 22, les galets 21 étant fous et les galets 22 motorisés à l'aide d'un moteur 23 et d'une transmission 24. The ferrule 1 rests horizontally on the base 5 by means of rollers 21 and 22, the rollers 21 being idle and the rollers 22 motorized using a motor 23 and a transmission 24.

Le fonctionnement du dispositif est le suivant :le tirant 11 étant escamote par sortie de la tige du vérin 12, l'opérateur positionne tout d'abord le coulisseau 9 à l'aide de la vis 8 et du moteur 7 de manière à ce que le bras 3 soit à la hauteur desirée, c'est- à-dire à ce qu'il vienne à l'intérieur de la virole à mettre en place dans le cas du soudage sur la paroi intérieure de cette dernière ou à l'extérieur de celle-ci dans le cas du soudage sur sa partie ex- terieure.  The operation of the device is as follows: the tie rod 11 being retracted by output from the rod of the jack 12, the operator first of all positions the slide 9 using the screw 8 and the motor 7 so that arm 3 is at the desired height, that is to say that it comes inside the shell to be put in place in the case of welding on the inner wall of the latter or outside of this in the case of welding on its outer part.

La virole i est alors amenée par des moyens de levage etde translation classiques non représentés à la place désirée, telle que celle représentée sur le dessin qui correspond au soudage de goujons sur la paroi intérieure sur les galets 2.1 et 22. Le tirant 11 est alors relevé par rétraction de la tige du vérin 12 et les axes 25 et 26 mis en place sur l'extrémité du bras 3. The ferrule i is then brought by conventional lifting and translating means not shown in the desired place, such as that shown in the drawing which corresponds to the welding of studs on the inner wall on the rollers 2.1 and 22. The tie rod 11 is then raised by retraction of the rod of the jack 12 and the pins 25 and 26 placed on the end of the arm 3.

L'opérateur monte alors à l'intérieur de la virole sur lequel on a effectué un traçage permettant de déterminer tous les endroits de fixation des goujons. Il peut alors, après avoir fixé un goujon 2 dans le mandrin 16, agir à distance sur les moteurs 24 et 13 pour déplacer par rotation la virole l, d'une part1 et par translation le chariot 6, d'autre part, de manière à positionner le goujon 2 à l'endroit désiré. Il déclenche alors le fonctionnement de l'ensemble 17, 15, 14, 12, 20, 18, 19 de soudage par friction dudit goujon. Après soudure de ce dernier et retrait du mandrin 16, Il fixe sur ce dernier un autre goujon et le soude de même à la place tracée après avoir déplacé le chariot 6 et éventuellement la virole 1 en conséquence. The operator then climbs inside the shell on which a tracing has been carried out making it possible to determine all the locations for fixing the studs. It can then, after having fixed a stud 2 in the mandrel 16, act remotely on the motors 24 and 13 to move the ferrule l by rotation, on the one hand1 and by translation the carriage 6, on the other hand, so to position the stud 2 at the desired location. It then triggers the operation of the assembly 17, 15, 14, 12, 20, 18, 19 for friction welding of said stud. After welding of the latter and removal of the mandrel 16, it fixes on the latter another stud and the same soda in the place traced after having moved the carriage 6 and possibly the ferrule 1 accordingly.

Il est également possible d'automatiser le fonctionnement de la machine, d'une part, en montant éventuellement les pièces à souder 2 dans le mandrin 16 à l'aide d'un dispositif classique de chargement automatique ; d'autre part, en automatisant e-ventuelle- ment de manière classique le fonctionnement des différents moteurs 23 et 13, embrayage 15, vérin de poussée 2Q, par programmage traditionnel, ce qui permet d'éviter l'execution du traçage a l'intérieur de la virole puisque celui-ci est inclus dans le programme de fonctionnement de tous ces éléments.  It is also possible to automate the operation of the machine, on the one hand, by optionally mounting the parts to be welded 2 in the mandrel 16 using a conventional automatic loading device; on the other hand, by e-possibly automating in a conventional manner the operation of the various motors 23 and 13, clutch 15, thrust cylinder 2Q, by traditional programming, which makes it possible to avoid the execution of the tracing with the inside the shell since it is included in the operating program of all these elements.

L'invention trouve son utilisation principale dans le domaine de la fabrication de capacités chaudronnées destinées aux unités de raffinage ou de transformation de produits pétrochimiques. The invention finds its main use in the field of the manufacture of boilers for the refining or transformation of petrochemical products.
