Description
Installation pour le soudage électrique de métaux.
L'objet de la présente invention est une installation du genre de celles comprenant une bobine destinée à être parcourue par du courant alternatif qui engendre, dans les pièces à souder, des courants de Foucault chauffant celles-ci. L'installation est caractérisée en ce que la bobine susmendonnée présente deux parties terminées en cônes, les sommets de ceux-ci étant disposés en face l'un de l'autre et laissant entre eux un espace libre où se concentrent les lignes de force.
Le dessin ci-annexé représente, à titre d'exemple et partiellement, deux formes d'exécution de l'objet de l'invention.
La fig. 1 est une coupe axiale de la bobine de la première forme d'exécution ; la fig. 2 est une coupe par II-II de la fig. 1 ; la fig. 3 est une vue, analogue à celle de fig. 2, d'une variante ; la fig. 4 montre la bobine de la seconde forme d'exécution.
La bobine représentée aux fig. 1 et 2 est constituée par un fil conducteur 1 isolé et enroulé sur lui-même en plusieurs couches, de façon à former deux cônes 2 et 3, à section droite circulaire, ayant leurs sommets en regard et à distance l'un de l'autre. Dans l'espace 4 situé entre ces deux sommets, et où les lignes de force de la bobine se trouvent concentrées sur une étroite surface, on introduit les extrémités des pièces à souder, par exemple les extrémités de deux barres métalliques. Lorsque la bobine est parcourue par du courant alternatif, de préférence à haute fréquence, celui-ci engendre, dans les extrémités à souder, des courants de Foucault qui portent lesdites extrémités à haute température et les fondent.
La bobine pourrait aussi avoir une section droite oblongue, comme montré en fig. 3, ce qui convient spécialement pour la soudure le long de lignes, par exemple pour la soudure de tôles.
En fig. 4,5 est une bobine en forme de tore, à axe circulaire et présentant en 6 une solution de continuité limitée par les deux cônes 7 et 8 dont les sommets se font face.
Dans 1'espace libre 6, s'engagent les extrémi- tés à souder.
Grâce à la forme en tore de la bobine 5, la totalité du flux magnétique de cette dernière se trouve utilisé.
Bien entendu, les bobines susmentionnées pourraient présenter à leur intérieur un noyau en métal,-par exemple en fer.
Installation for electric welding of metals.
The object of the present invention is an installation of the type of those comprising a coil intended to be traversed by the alternating current which generates, in the parts to be welded, eddy currents heating them. The installation is characterized in that the aforementioned coil has two parts terminated in cones, the tops of the latter being arranged opposite one another and leaving between them a free space where the lines of force are concentrated.
The appended drawing represents, by way of example and partially, two embodiments of the object of the invention.
Fig. 1 is an axial section of the coil of the first embodiment; fig. 2 is a section through II-II of FIG. 1; fig. 3 is a view, similar to that of FIG. 2, of a variant; fig. 4 shows the coil of the second embodiment.
The coil shown in fig. 1 and 2 consists of a conductive wire 1 insulated and wound on itself in several layers, so as to form two cones 2 and 3, with a circular cross section, having their tops opposite and at a distance from one of the other. In the space 4 located between these two vertices, and where the lines of force of the coil are concentrated on a narrow surface, the ends of the parts to be welded, for example the ends of two metal bars, are introduced. When the coil is traversed by alternating current, preferably at high frequency, the latter generates, in the ends to be welded, eddy currents which bring said ends to high temperature and melt them.
The coil could also have an oblong straight section, as shown in fig. 3, which is especially suitable for welding along lines, for example for welding sheet metal.
In fig. 4,5 is a coil in the form of a torus, with a circular axis and having at 6 a solution of continuity limited by the two cones 7 and 8 whose vertices face each other.
In the free space 6, engage the ends to be welded.
Thanks to the toroidal shape of the coil 5, all of the magnetic flux of the latter is used.
Of course, the aforementioned coils could have a metal core, for example iron, inside them.
