Description
Procede de fabrieation de fiotteurs metalliques. L'invention se rapporte ä un procedd de fabrication de flotteurs mdtalliques, applica- ble par exemple ä la fabrication des flotteurs de carburateurs et des flotteurs pour 'appa- reils sanitaires. Process for the manufacture of metal floats. The invention relates to a process for the manufacture of metal floats, applicable for example to the manufacture of floats for carburettors and floats for sanitary appliances.
Comme an 1e sait, les flotteurs prdcitds sont gendralement etablis. en laiton, en cui- vre ou en töle de fer ou d'acier tres mince, ce qui oblige ä les constituer de plusieurs pieces assemblees par soudure. Toutefois, par suite de la tres faible epaisseur de la feuille de metal employe, ces assemblages soudds manquent tres frdquemment d'etarrchditd, ce qui nuit considdrablement au fonctionnement et ä la bonne marche des flotteurs. As we know, the aforementioned floats are generally established. made of brass, copper or sheet iron or very thin steel, which means that they have to be made from several pieces assembled by welding. However, due to the very thin thickness of the metal sheet used, these welded assemblies very frequently lack sturdiness, which considerably impairs the operation and proper functioning of the floats.
Le procdde suivant 1'invention consiste ä emboutir un disque d'aluminium plan, mis en rotation, entre une matrice mobile placee du cöte ext6rieur du disque et une contre- matrice fixe placee du cötd interieur de celui-ci, en faisant ddplacer la matrice mo bile exterieure de maniere que 1e mdtal dpouse la forme de la contre-matrice intd- rieure, laquelle est conformee pour qu'ä la fin de cette operation 1'dbauche sofft formde d'un Premier fond prolonge par un corps dont 1'extremitd est ouverte et prdsente un diametre inferieur ä celui de la Partie prin- cipale de. ce corps, puis ä enlever la contre- matriee irrterieure, ä adapter sur 1'dbauche une matrice extdrieure ä serrage progressif en meme temps que Fon chauffe legerement, de maniere ä retrdcir de plus en plus 1'extr6- mite. du corps de 1'ebauche jusqu'ä ce que celle-ei se ferme par jonctionnement du metal. The process according to the invention consists in stamping a flat aluminum disc, set in rotation, between a mobile die placed on the outside of the disc and a fixed counter-die placed on the inside of the latter, by causing the die to move external mobile so that the metal matches the shape of the internal counter-die, which conforms so that at the end of this operation the blank is formed from a First bottom extended by a body whose extremity is open and has a diameter less than that of the main part of. this body, then removing the inner counter-die, fitting onto the blank an outer die with progressive tightening at the same time as it heats slightly, so as to shrink the end more and more. of the body of the blank until it closes by joining the metal.
Dans ce qui suit, an ddcrira, ä titre d'exemple, un mode d'exdcution du procede faisant 1'objet de 1'invention. In what follows, an will describe, by way of example, a mode of execution of the process which is the subject of the invention.
0n Part d'un flan de töle d'aluminium mince, par exemple dune epaisseur variant entre 4/io et lo/io de millimetre, que 1'on monte sur un tour pour 1e faire tourner ä Brande vitesse et que 1'on presse en meme temps entre une matrice mobile placee du cötd ext6rieur du disque et une contre-matrice placee du cöte interieur de celui-ci, tont en faisant deplacer la matrice mobile extdrieure de maniere que 1e mdtal dpouse la forme de la contre-matrice iriterieure, laquelle est con- form6e pour qdä la fin de cette operation 1'ebauche sofft formee d'un Premier fond pro long6 par un Corps dont l'extremite est ou- verte et presente un diametre inferieur ä celui de la Partie principale de ce Corps; ensuite an enleve la contre-matrice interieure et an adapte sur l'ebauche une matrice exte- rieure ä serrage progressif en meine temps que 1'on chauffe legerement 1'extrgmite ou- verte du Corps de 1'ebauche. Gräce ä la tem- p6rature developpee par la rotation rapide du mUal, aidee par la chaleur externe apportee, 1'extremite ouverte du Corps metallique se referme sous Paction de la matrice exterieure ä serrage progressif. Le second fond du flot- teur se forme ä mesure que Pouverture libre de l'extremite du Corps se resserre pour finir par disparaitre, 1e mötal se jonctionnant au- tomatiquement. 0n Starts with a blank of thin aluminum sheet, for example of a thickness varying between 4/io and lo/io of a millimeter, which is mounted on a lathe to make it turn at high speed and which is pressed at the same time between a movable die placed on the outer side of the disc and a counter-die placed on the inner side of the latter, all by moving the outer movable die so that the metal matches the shape of the inner counter-die, which conforms so that at the end of this operation the blank is formed of a First bottom extended by a Body whose end is open and has a diameter less than that of the main part of this Body; then the inner counter-die is removed and a progressively clamped outer die is fitted to the blank while the open end of the body of the blank is slightly heated. Thanks to the temperature developed by the rapid rotation of the mUal, aided by the external heat supplied, the open end of the metallic body closes under the action of the external matrix with progressive tightening. The second bottom of the float forms as the free opening in the end of the Body narrows and eventually disappears, the metal joining automatically.
Lorsqu'il s'agit d'un flotteur, tel par exemple que celui d'un appareil sanitaire oü il est necessaire de prevoir un organe de fixation de la tige du flotteur, 1'on mdnage d'abord dann 1e disque plat, par emboutis- sage au centre de ce disque monte sur 1e tour et tournant avec lui, un evidement con- veriable pour 1e logement de cet organe; puls, ce dernier est enga.ge dans 1'evidement en question et 1e metal du disque est serti interieuremerit autour de cet organe qui se trouve ainsi solidement emprisonn6; enfin, l'emboutissage du Premier fond et du Corps, puls celui du deuxieme fond sont produits de la meine fagon que dans 1e cas pr6cedent. In the case of a float, such as that of a sanitary appliance, for example, where it is necessary to provide a member for fixing the stem of the float, it is first fitted in the first flat disc, by stamping in the center of this disk mounted on the lathe and rotating with it, a suitable recess for the housing of this organ; puls, the latter is enga.ge in 1'evidement in question and the first metal of the disc is crimped interieuremerit around this body which is thus firmly imprisonn6; finally, the stamping of the First bottom and the Body, as well as that of the second bottom are produced in the same way as in the previous case.
Une forme d'exkution du produit obtenu par 1e procedd dkrit est representde, ä titre d'exemple, au dessin annexe. One embodiment of the product obtained by the process described is shown, by way of example, in the accompanying drawing.

Sur cette figure, a represente la paroi d'aluminium mince en une Beule piece; b est une Pointe de cen- trage et c est 1e point oiz s'est ferme 1'extre- niite de diametre restreint du Corps de Vebauche. fig. 1 shows a longitudinal section of an aluminum carburettor float in a Beule pike. In this figure, a represents the thin aluminum wall in one piece; b is a Center Point and c is the point where the restricted diameter end of the Blank Body is closed.
La fig. 2 montre, egalement en coupe longitudinale, un flotteur en aluminium dune Beule piece, pour appareil de chasse, obtenu conformement au procede decrit. Sur cette figure, a designe la paroi continue en alu- minium dune Beule piece; d 1'evidement continu obtenu par emboutissage dans 1e flan ou disque plag e designe 1e tube taraude pour la fixation de la tige de commande et ei une saillie cireulaire prdvue sur la face externe de ce tube pour assurer Bon main- tien. Le sertissage deRTI ID="0002.0275" WI="3" HE="4" LX="1622" LY="779"> ce tube a etd obtenu par Paction d'outils agissant suivant une di- rection convenable en f, quand 1e flan etait encore sous forme de disque plat g. fig. 2 shows, also in longitudinal section, an aluminum float of one Beule piece, for a hunting device, obtained in accordance with the process described. In this figure, a designates the continuous aluminum wall of a single piece; d the continuous recess obtained by stamping in the blank or beach disc designates the threaded tube for fixing the control rod and ei a circular projection provided on the external face of this tube to ensure good maintenance. The crimping of RTI ID="0002.0275" WI="3" HE="4" LX="1622" LY="779"> this tube was obtained by the action of tools acting in a suitable direction at f, when the blank was still in the form of a flat disc g.
