Description

La présente invention concerne les dispositifs pour l'usinage de métaux par déformation et a notamment des outils pour l'étirage ou le tréfilage de produits avec utilisation d'un lubrifiant sous pression. The present invention relates to devices for machining metals by deformation and in particular has tools for drawing or drawing products with the use of a pressurized lubricant.

L'invention est applicable avec succès à l'étirage (au tréfilage) de produits de tous types et destinations (tels que, par exemple : fils, barres, tubes) sur tous les types de bancs d'étirage (de tréfilage) exploités actuellement. The invention is applicable successfully to the drawing (drawing) of products of all types and destinations (such as, for example: wires, bars, tubes) on all types of drawing benches (drawing) currently used .

L'évolution actuelle de la production industrielle exige une intensification du processus d'étirage (de tréfilage) grace à l'augmentation des vitesses d'étirage, des réductions, de même que de la durée de service des outils utilisés. The current development of industrial production requires an intensification of the drawing (drawing) process thanks to the increase in drawing speeds, reductions, as well as the service life of the tools used.

On connait un outil d'étirage (de tréfilage) de produits avec utilisation d'un lubrifiant sous pression (cf. certificat d'auteur d'invention URSS NO 165 416, cl. B21C3/14, publié le 12 Octobre 1964) comportant dans un corps une douille conique fendue de serrage, à l'intérieur de laquelle sont disposés successivement (dans le sens de défilement du produit) une douille de pression, un élément d'étanchéité et au moins une filière de travail en contact entre eux. There is a known tool for drawing (drawing) products using a pressurized lubricant (cf. USSR inventor certificate NO 165 416, cl. B21C3 / 14, published on October 12, 1964) comprising in a body a conical split clamping bushing, inside which are successively arranged (in the direction of travel of the product) a pressure bushing, a sealing element and at least one working die in contact with each other.

Cependant, l'étanchéité de cet outil n'est pas suffisamment fiable dans les conditions de déformations thermiques et mécaniques apparaissant au cours de l'étirage (tréfilage), ce qui conduit à une baisse de la pression du lubrifiant et, par conséquent, de son efficacité. However, the tightness of this tool is not sufficiently reliable under the conditions of thermal and mechanical deformations appearing during drawing (drawing), which leads to a drop in the pressure of the lubricant and, consequently, of its efficiency.

De plus, lorsque let amètre extérieur de la douille de pression est supérieur à celui de la filière de travail, cette dernière s'avère insuffisamment serrée dans le sens radial, ce qui conduit à sa cassure pendant l'étirage (tréfilage),
L'invention a pour objectif de créer un outil pour l'étirage (tréfilage) de produits avec utilisation d'un lubrifiant sous pression, dont l'élément d'étanchéité serait réalisé de façon à permettre d'accroître la fiabilité de fonctionnement de l'outil et l'intensité du processus d'étirage.In addition, when the outside meter of the pressure sleeve is greater than that of the working die, the latter turns out to be insufficiently tightened in the radial direction, which leads to its breaking during drawing (drawing),
The object of the invention is to create a tool for drawing (drawing) products using a pressurized lubricant, the sealing element of which would be made so as to increase the operating reliability of the tool and intensity of the stretching process.

La solution consiste en ce que l'outil, comportant un corps dans lequel est montée une douille conique fendue de serrage dans laquelle sont placés successivement (dans le sens de défilement du produit) une douille de pression, un élément d'étanchéité et au moins une filière de travail en contact entre eux, est doté, selon l'invention, d'une douille flottante d'étanchéité qui est placée avec un jeu radial dans un chambrage de la douille conique fendue de serrage de façon telle que ladite douille flottante d'étanchéité entoure la douille de pression ainsi que la filière de travail sur sensiblement 0,1 à 0,3 de sa longueur. The solution consists in that the tool, comprising a body in which is mounted a conical split clamping sleeve in which are successively placed (in the direction of travel of the product) a pressure sleeve, a sealing element and at least a working die in contact with each other, is provided, according to the invention, with a floating sealing bushing which is placed with a radial clearance in a recess of the conical split clamping bushing such that said floating bushing d the seal surrounds the pressure sleeve as well as the working die over substantially 0.1 to 0.3 of its length.

Il est avantageux que la partie de la douille conique fendue de serrage entourant la douille flottante d'étanchéité comporte au moins une fente longitudinale. It is advantageous that the part of the conical split clamping sleeve surrounding the floating sealing sleeve has at least one longitudinal slot.

La présente invention améliore la fiabilité de l'étanchéité dans les conditions de déformations thermiques et mécaniques, ce qui permet d'augmenter la vitesse d'étirage (de tréfilage) et de réduction et de diminuer la rupture des produits au cours de l'étirage (tréfilage). The present invention improves the reliability of the seal under thermal and mechanical deformation conditions, which makes it possible to increase the speed of drawing (drawing) and of reducing and reducing the breakage of the products during drawing. (wire drawing).

1a outre, l'invention diminue le risque de mise hors d'usage des filières de travail par usure ou rupture. 1a moreover, the invention reduces the risk of the working dies being put out of use by wear or breakage.

L'invention sera mieux comprise et d'autres buts, détails et avantages de celle-ci apparaîtront mieux à la lumière de la description explicative qui va suivre de différents modes de réalisation donnés uniquement à titre d'exemples non limitatifs, avec référence au dessin unique non limitatif annexé dans lequel
- la figure 1 représente une vue d'ensemble, en coupe longitudinale, d'un outil d'étirage (de tréfilage) de produits avec utilisation d'un lubrifiant sous pression, selon l'invention.The invention will be better understood and other objects, details and advantages thereof will appear better in the light of the explanatory description which will follow of different embodiments given only by way of nonlimiting examples, with reference to the drawing. single nonlimiting annexed in which
- Figure 1 shows an overall view, in longitudinal section, of a drawing tool (drawing) of products with the use of a pressurized lubricant, according to the invention.

- la figure 2 est une vue en perspective, isométrique d'ensemble de la douille conique fendue de serrage apparaissant sur la figure 1, selon l'invention. - Figure 2 is an isometric, perspective view of the conical split clamping sleeve appearing in Figure 1, according to the invention.

L'outil d'étirage (de tréfilage) de produits avec utilisation d'un lubrifiant sous pression comporte une douille conique fendue de serrage 2 (figures 1, 2) placée dans un corps 1 (figure 1). Une douille de pression 4, un élément d'étanchéité 5 et une filière de travail 6 en contact entre eux sont disposés successivement, dans le sens de défilement du produit 3 (appelé "fil 3" dans la suite de la présente description), à l'intérieur de la douille conique fendue de serrage 2 (figure 1). L'espace séparant la douille 4 de la filière 6 est rempli de lubrifiant 7. The tool for drawing (drawing) products using a pressurized lubricant comprises a conical split clamping sleeve 2 (Figures 1, 2) placed in a body 1 (Figure 1). A pressure sleeve 4, a sealing element 5 and a working die 6 in contact with each other are arranged successively, in the direction of travel of the product 3 (called "wire 3" in the remainder of this description), to inside the conical split clamping sleeve 2 (figure 1). The space separating the bush 4 from the die 6 is filled with lubricant 7.

Dans un chambrage réalisé dans la douille 2, est placée, avec un jeu radial par rapport à cette dernière, une douille flottante d'étanchéité 8 de manière que celle-ci entoure la douille 4, ainsi que la filière 6 de préférénce sur 0,2 de la longueur de cette dernière. La douille 2 (figures 1, 2) comporte une fente 9 dans sa partie embrassant la douille 8. In a recess made in the socket 2, is placed, with a radial clearance relative to the latter, a floating sealing socket 8 so that the latter surrounds the socket 4, as well as the die 6 preferably on 0, 2 the length of the latter. The socket 2 (FIGS. 1, 2) has a slot 9 in its part embracing the socket 8.

Un chapeau de serrage 10 est relié au corps 1.A tightening cap 10 is connected to the body 1.

Lors de l'assemblage de l'outil, conforme à l'invention, pour le tréfilage (figure 1) avec utilisation d'un lubrifiant 7 sous pression, la filière de travail 6 devient plus serrée dans le sens radial indépendamment du diamètre de la douille de pression 4, ce qui diminue le risque de rupture et de mise hors d'usage de la filière de travail 6. When assembling the tool, according to the invention, for drawing (FIG. 1) with the use of a lubricant 7 under pressure, the working die 6 becomes tighter in the radial direction independently of the diameter of the pressure sleeve 4, which reduces the risk of breakage and disabling of the working die 6.

L'outil de tréfilage avec utilisation d'un lubrifiant sous pression fonctionne de la façon suivante. The drawing tool using a pressurized lubricant works as follows.

Le fil 3 (figure 1) passe à travers la douille de pression 4 et s'engage dans la filière de travail 6.  The wire 3 (Figure 1) passes through the pressure sleeve 4 and engages in the working die 6.

Hors de son passage à travers la douille de pression 4, le fil 3 refoule le lubrifiant 7 en créant une haute pression dans la zone située entre la douille 4 et la filière 6. Il se produit alors une séparation des surfaces frottantes du fil 3 d'avec la filière de travail 6, ce qui permet d'accroître la vitesse de tréfilage et de réduction et diminue en outre l'usure de la filière de travail 6.Out of its passage through the pressure sleeve 4, the wire 3 discharges the lubricant 7 by creating a high pressure in the area between the sleeve 4 and the die 6. There then occurs a separation of the friction surfaces of the wire 3 d 'with the working die 6, which increases the drawing speed and reduction and further reduces the wear of the working die 6.

Suivant l'invention, la présence d'un chambrage dans la douille conique fendue de serrage 2 en combinaison avec la fente longitudinale 9 (figure 2) permet d'utiliser la douille 2 et la douille 8 comme un ensemble formant un tout, ce qui simplifie les opérations d'assemblage et de démontage de l'outil. According to the invention, the presence of a recess in the conical split clamping sleeve 2 in combination with the longitudinal slot 9 (FIG. 2) makes it possible to use the sleeve 2 and the sleeve 8 as a whole forming a whole, which simplifies assembly and disassembly of the tool.

Bien entendu, l'invention n'est nullement limitée aux modes de réalisation décrits et représentés qui n'ont été donnés qu'à titre d'exemples. En particulier, elle comprend tous les moyens constituant des équivalents techniques des moyens décrits, ainsi que leurs combinaisons, si celles-ci sont exécutées suivant son esprit et mises en oeuvre dans le cadre de la protection comme revendiquée.  Of course, the invention is in no way limited to the embodiments described and shown which have been given only by way of examples. In particular, it includes all the means constituting technical equivalents of the means described, as well as their combinations, if these are executed according to the spirit and implemented in the context of protection as claimed.
