Abstract

A spray head for the distribution of liquid or viscous materials, e.g. corrosion protection materials, on the inside of box-like metal profile parts has a rotatable ring (14) which carries the spray openings (24) and is set in rotation, when used according to its purpose, under the action of the reaction force which arises.

Description

La présente invention a pour objet une tête de pulvérisation destinée à être reliée à un pistolet par Ün tuyau pour pulvériser des matières liquides ou semi-denses mélangées à de l'air, par exemple de matières protectrices anticorrosives, à l'intérieur de profilés métalliques fermés en caisson tels que les longerons passant sous les portes des véhicules automobiles, ainsi que les traverses de renforcement de ces véhicules. The subject of the present invention is a spray head intended to be connected to a gun by a hose for spraying liquid or semi-dense materials mixed with air, for example anticorrosive protective materials, inside metal profiles. closed in a box such as the side rails passing under the doors of motor vehicles, as well as the reinforcing cross members of these vehicles.

Dans l'état actuel de la technique, la pulvérisation de ces matières anticorrosives s'effectue à l'aide d'un pistolet relié par un tuyau à une tête de pulvÇrisa- tion que l'opérateur introduit dans des trous pratiqués dans les profilés fermés qu'il s'agit de traiter avec ces substances. In the current state of the art, the spraying of these anticorrosive materials is carried out using a gun connected by a hose to a spray head which the operator introduces into holes made in the closed profiles. that it's about dealing with these substances.

Toutefois, cette solution crée des inconvénients notables en ce sens que, pour permettre une distribution uniforme de la matière à l'intérieur du profilé fermé, la tête doit possèder des trous multiples orientés en fonction de la géomètrie du profilé à traiter. However, this solution creates notable drawbacks in that, to allow a uniform distribution of the material inside the closed profile, the head must have multiple holes oriented according to the geometry of the profile to be treated.

Par ailleurs, il peut se produire que, pour pouvoir être entièrement recouverts de la substance anticorrosive, certains profilés fermés exigent de la part de l'op6- rateur plusieurs introductions de la même tête ou de têtes possédant des trous différemment orientés, ce qui entratne une grande perte de temps et un prix de revient élevé en main d'oeuvre. In addition, it may happen that, in order to be completely covered with the anticorrosive substance, certain closed sections require from the operator several introductions of the same head or of heads having differently oriented holes, which leads to a great waste of time and a high cost price in manpower.

L'invention vise à résoudre avantageusement ces problèmes en réalisant une tette de pulvérisation qui permette une répartition plus uniforme de la matière et qui permette de recouvrir de plus grandes zones avec une notable économie de temps dans l'exécution des opérations. The invention aims to advantageously solve these problems by producing a spraying cap which allows a more uniform distribution of the material and which makes it possible to cover larger areas with a notable saving of time in the execution of the operations.

La présente invention atteint ces buts au moyen d'une tête de pulvérisation caractérisée en ce que,sur la surface extérieure du corps est montée rotative une bague qui présente les trous de sortie, lesdits trous étant dirigés tangentiellement au corps de la tête, de sorte que, lors de l'utilisation, ladite bague tourne par rapport au corps par réaction. The present invention achieves these objects by means of a spray head characterized in that, on the external surface of the body, there is rotatably mounted a ring which has the outlet holes, said holes being directed tangentially to the body of the head, so that, in use, said ring rotates relative to the body by reaction.

D'autres caractéristiques et avantages de l'invention seront mieux compris a la lecture de la description qui va suivre d'un exemple de réalisation et en se référant aux dessins annexés sur lesquels,
la figure 1 est une vue en coupe de la tête selon l'invention ;
la figure 2 est une vue en coupe selon la ligne A-A de la figure 1.
Other characteristics and advantages of the invention will be better understood on reading the description which follows of an embodiment and with reference to the appended drawings in which,
Figure 1 is a sectional view of the head according to the invention;
Figure 2 is a sectional view along line AA of Figure 1.

Sur la figure 1, on a représenté en 4 l'ensemble de la tête qui est composée d'un corps 6 de forme cylindrique se terminant à une extrémité par une queue 8 sur laquelle on emmanche un tuyau flexible 10 servant a raccorder la tête à un pistolet de pulvérisation non repré senté sur le dessin
Le corps 6 présente à son autre extrémité une partie cylindrique 12 de diamètre réduit sur laquelle est formée une gorge annulaire 14.
In Figure 1, there is shown in 4 the entire head which is composed of a body 6 of cylindrical shape ending at one end by a tail 8 on which is connected a flexible pipe 10 used to connect the head to a spray gun not shown in the drawing
The body 6 has at its other end a cylindrical part 12 of reduced diameter on which an annular groove 14 is formed.

Sur la partie 12 est montéerotative une bague cylindrique 16 qui prend appui à une extrémité sur une paroi plane 18 du corps 6. On the part 12 is rotatably mounted a cylindrical ring 16 which bears at one end on a flat wall 18 of the body 6.

Le corps 6 présente un trou longitudinal 20 et une série de trous radiaux 22 qui débouchent dans la gorge annulaire 14. The body 6 has a longitudinal hole 20 and a series of radial holes 22 which open into the annular groove 14.

La bague 16 est percée d'une série de trous 24 pratiqués dans des directions sensiblement tangentielles à sa paroi intérieure et qui présentent un évasement 26 à leur partie qui débouche à l'extérieur. The ring 16 is pierced with a series of holes 24 made in directions substantially tangential to its inner wall and which have a flare 26 at their part which opens to the outside.

Le corps 6 se termine par une partie cylindrique 28 de plus petit diamètre que la partie 12 et par une partie filetée 30. The body 6 ends in a cylindrical part 28 of smaller diameter than the part 12 and in a threaded part 30.

La bague 16 est maintenue dans sa position par un bouchon 32 en forme d'ogive qui est vissé sur la partie filetée 30 et s'appuie sur une partie plane 34 de la partie 12.  The ring 16 is held in its position by a plug 32 in the form of an ogive which is screwed onto the threaded part 30 and rests on a flat part 34 of the part 12.

Dans le fonctionnement, on introduit la tête de pulvérisation dans un trou d'un profilé metallique fermé. In operation, the spray head is introduced into a hole in a closed metal profile.

La matière fluide fournie sous pression par un pistolet et qui arrive par le tuyau 10 passe dans les trous 20 et 22 puis, par la gorge 14, elle pénètre dans les trous 24 de la bague 16 t en tournant par réaction sous l'effet de la pression du jet, cette bague distribue uniformément la matière dans toutes les directions indépendamment de la forme géométrique du profilé fermé.The fluid material supplied under pressure by a gun and which arrives through the pipe 10 passes through the holes 20 and 22 then, through the groove 14, it enters the holes 24 of the ring 16 t by rotating by reaction under the effect of the pressure of the jet, this ring distributes the material uniformly in all directions regardless of the geometric shape of the closed profile.

Bien entendu, différentes modifications pourront etre apportées par l'homme de l'art au dispositif qui vient d'être décrit uniquement à titre d'exemple non limitatif sans pour cela sortir du cadre de l'invention.  Of course, various modifications may be made by those skilled in the art to the device which has just been described solely by way of nonlimiting example without thereby departing from the scope of the invention.
