Abstract
Description
Le procédé de fabrication du fil de laiton carre, surtout 1,2 x 1,2 2 irmi > étame, est le sujet de l'invention. The method of manufacturing the square brass wire, especially 1.2 × 1.2 2 μmiame, is the subject of the invention.
Selon les procédés connus de fabrication du fil de laiton carre, étamés les fils mentionnes sont produits au moyen du travail à froid, le plus souvent par laminage, en utilisant le traitement de recuit et celui d'etamage qui exigent la surface propre de produit. Pour cela, on se sert des machines spéciales pour le laminage, dans lesquelles la pression des ylindres est reglée automatiquement ensemble avec le changement de tolérance de production du fil. According to the known methods of manufacturing tinned brass wire, the son mentioned are produced by means of cold work, usually by rolling, using the annealing and tinning treatment which require the clean surface of the product. For this, special machines are used for rolling, in which the pressure of the ylinders is automatically adjusted together with the change of tolerance of production of the wire.
Ce procédé laisse obtenir les arêtes vives et l'epaisseur déterminée de l'étain sur la surface du fil, mais il a aussi un defaut en changements de la surface des arrondis à la longueur du fil. This method allows sharp edges and the determined thickness of the tin to be obtained on the surface of the wire, but it also has a defect in changes in the surface of the roundings to the length of the wire.
En outre, la couche superposée de l'tain est aigre et on voit des lieux non couverts sur la surface du fil, sous la forme de taches. Aussi, le traitement de recuit du fil/semi-produit exige l'utilisation des outils spéciaux au recuit sans voile. In addition, the superimposed layer of the tain is sour and uncovered places are seen on the surface of the wire, in the form of spots. Also, the annealing treatment of the wire / semi-product requires the use of special tools for annealing without a sail.
On connaît aussi le procede de fabrication du fil en acier austenitique selon le fascicule du brevet polonais n 90266, qui consiste à sursaturer le fil d'epaisseur de 7 mm à l'intervalKle 10500C-10800C dans l'eau et ensuite ce fil est tréfilé dans les filières jusqu'au diamètre de 2,91 mm, et de nouveau le fil est sursaturé dans la température 11300C-11500C dans l'eau et après tréfilé dans les filières lubrifiées à pression. On connait aussi le procede de fabrication et de travail du fil avec la machine travaillant en série; qui se compose de plusieurs ensembles travaillant, par lesquels le fil passe sans déroulage. C'est un fascicule de brevet anglais n 81221 accordé en Pologne. Also known is the method of manufacturing the austenitic steel wire according to the specification of the Polish Patent No. 90266, which consists of oversaturating the 7 mm thick wire at interval 10500C-10800C in water and then this wire is drawn. in the dies up to a diameter of 2.91 mm, and again the wire is supersaturated in the temperature 11300C-11500C in the water and after drawn into the pressure-lubricated dies. Also known is the method of manufacturing and working the wire with the machine working in series; which consists of several working sets, through which the thread passes without unwinding. This is a British Patent Specification No. 81221 granted in Poland.
Le procéde de travail du fil consiste à tréfiler le fil avec au moins deux filières et au moins un tambour de la machine à trefiler. La vitesse du filage est réglée. I1 faut tréfiler simul tapement au moins deux fils. L'entraînement de chaque machine est accouple à l'entraînement des tambours de la machine à tréfiler. Sur le fil chaud, sortant de la machine à tréfiler, par exemple le fil en aluminium, on superpose une couche d'étain par exemple. The method of working the wire is to draw the wire with at least two dies and at least one drum of the machine to thread. The spinning speed is set. Simul tapes must be drawn at least two wires. The drive of each machine is coupled to the drive of the drums of the drawing machine. On the hot wire coming out of the drawing machine, for example the aluminum wire, a layer of tin for example is superimposed.
Le but de l'invention, c'est l'élaboration du procédé de fabrication du fil de laiton étamé, éliminant le laminage et le recuit et l'application du procédé de trefiler le fil étamé antérieu- rement à chaud. The object of the invention is the development of the method of manufacturing the tinned brass wire, eliminating the rolling and annealing and the application of the method of extruding the tinned wire before heat.
La première étape du procedé suivant l'invention consiste à étamer à chaud le fil semi-produit au diamètre de 1 > 85 - 0,05 mm, en laiton à teneur en cuivre de 60 à 70% , ayant une résistance à la traction Rm=500 de 600 N/mm, et à tréfiler le fil rond au diamètre 1,72 + 0,02mm, se servant du lubrifiant dégraissé. The first step of the process according to the invention consists in hot-tinning the semi-finished wire with a diameter of 1> 85 - 0.05 mm, brass with a copper content of 60 to 70%, having a tensile strength Rm = 500 of 600 N / mm, and to wire the round wire to the diameter 1.72 + 0.02mm, using degreased lubricant.
Le fil ainsi préparé n'exige pas de long traitement de recuit et sa surface est propre. A la seconde étape, le semiproduit de la première étape est tréfilé avec l'écrouissage : 10 à 30% par la filière profilee qui a dans la partie de calibrage la section transversale sous la forme d'epitrochoide. Ensuite, le fil à section transversale d'bpitrochoïde est tréfilé par la filière qui a dans la partie de calibrage la section carrée aux dimensions 1,2 x 1,2 mm
Le fil carré obtenu de cette façon possède sur sa surface une couche d'étain ou d'alliage d'etain se caractérisant d'une adhérence importante au support et d'une épaisseur de 3 à 8 micromètres.The yarn thus prepared does not require a long annealing treatment and its surface is clean. In the second step, the semiproduct of the first step is drawn with the work hardening: 10 to 30% by the profiled die which has in the sizing portion the cross section in the form of epitrochoid. Then, the cross-section of bpitrochoid wire is drawn by the die which has in the calibration part the square section with dimensions 1.2 x 1.2 mm
The square wire obtained in this way has on its surface a layer of tin or tin alloy characterized by a high adhesion to the support and a thickness of 3 to 8 microns.
Dans le procede décrit, suivant l'invention, la forme et la tolérance de fabrication du fil sont déterminées par la qualité de la filière finale et par le procédé de tréfiler. In the process described according to the invention, the form and the tolerance of manufacture of the yarn are determined by the quality of the final die and by the drawing process.
