Description

Dispositif porte-outils pour des machines d'étirage travaillant en continu.Tool holder device for continuous working stretching machines.

L'invention concerne un dispositif porteoutils pour des machines d'étirage travaillant en continu pour l'étirage d'un tube d'acier ou pour l'étirage simultané de plusieurs tubes d'acier. The invention relates to a tool holder for drawing machines working continuously for drawing a steel tube or for drawing several steel tubes simultaneously.

De façon connue, dans le cas de machines d'étirage comportant des chariots d'étirage effectuant un mouvement de vaet-vient et entraînés par des moyens mécaniques ou hydrauliques, les tubes à étirer sont serrés, au niveau de la section transversale déjà étirée, par des mâchoires de serrage semi-circulaires montées dans les chariots d'étirage et sont étirés par la lunette ou bague d'étirage.Le fait de conserver la conformation structurelle de principe, mise en oeuvre jusqu'alors dans des machines d'étirage simple, des chariots d'étirage - un tel chariot servant de "piece d'entrainement" et "l'outil de serrage" formant une unité de construction indivisible - conduirait pour une machine d'étirage multiple correspondante à des inconvénients déterminés en ce qui concerne l'encombrement résultant en raison des écartements importants entre les axes d'étirage et lors du changement d'outils. In a known manner, in the case of stretching machines comprising stretching carriages reciprocating and driven by mechanical or hydraulic means, the tubes to be stretched are tightened, at the level of the already stretched cross section, by semi-circular clamping jaws mounted in the stretching carriages and are stretched by the telescope or stretching ring. The fact of maintaining the structural structure in principle, implemented until then in simple stretching machines , stretching carriages - such a carriage serving as a "drive piece" and the "tightening tool" forming an indivisible construction unit - would lead to a drawback machine corresponding to certain drawbacks with regard to the resulting space due to the large spacings between the drawing axes and when changing tools.

Dans le cas de bancs d'étirage de type usuel, comportant des chariots d'étirage et un dispositif de rappel, on connait des constructions avec lesquelles on peut étirer simultanément côte à côte jusqu'à cinq tubes, en vue d'accroître la capacité. La longueur des tubes à fabriquer dépend de la longueur de l'installation. In the case of drawing benches of the usual type, comprising drawing carriages and a return device, constructions are known with which it is possible to stretch up to five tubes side by side simultaneously, in order to increase the capacity. . The length of the tubes to be produced depends on the length of the installation.

Dans le domaine des machines d'étirage comportant des chariots d'étirage effectuant un mouvement de va-et-vient, on ne connaît pas ce genre de constructions. In the field of stretching machines comprising stretching carriages performing a back-and-forth movement, this type of construction is not known.

L'invention a pour but de créer un dispositif porte-outils pour des machines d'étirage travaillant en continu, à l'aide duquel on puisse effectuer aussi bien un étirage simple que des étirages multiples, par exemple des étirages triples ou quintuples. The object of the invention is to create a tool holder device for stretching machines working continuously, with the aid of which it is possible to carry out both a simple stretching and multiple stretchings, for example triple or quintuple stretchings.

Pour résoudre ce problème,il est proposé, conformment à l'invention, un dispositif porte-outils pour des machines d'étirage travaillant en continu pour l'étirage d'un tube d'acier ou pour l'étirasse simultané de plusieurs tubes d'acier, caractérisé par le fait que le chariot d'étirage est sépare des outils de serrage et loge plusieurs unités d'outils de serrage en forme de cassettes.  To solve this problem, there is proposed, in accordance with the invention, a tool-holding device for drawing machines working continuously for drawing a steel tube or for the simultaneous drawing of several tubes of steel, characterized in that the drawing carriage is separated from the clamping tools and houses several units of clamping tools in the form of cassettes.

En outre, pour l'étirage simple, un logement pour cassette est ménagé au centre du chariot d'étirage et, pour des étirages multiples, les logements pour cassettes sont disposés symétriquement par rapport au centre. In addition, for single stretching, a cassette housing is provided in the center of the stretching carriage and, for multiple stretching, the cassette housings are arranged symmetrically with respect to the center.

Selon l'invention, les outils de serrage en forme de cassette sont munis de dispositifs de blocage. According to the invention, the cassette-shaped clamping tools are provided with locking devices.

Avantageusement, le chariot d'étirage pour chaque outil de serrage est équipé d'un dispositif de commande qui, lors de la mise en place de l'outil de serrage dans le chariot d'étirage, est relié aux organes d'accouplement, situés sur le chariot d'étirage, du dispositif de commande. En outre, le premier chariot d'étirage est équipé, de façon connue, de pinces à tirer. Advantageously, the drawing carriage for each clamping tool is equipped with a control device which, when the clamping tool is placed in the drawing carriage, is connected to the coupling members, located on the drawing carriage, of the control device. In addition, the first drawing carriage is equipped, in a known manner, with grippers.

Enfin, les outils de servage en forme de cassettes peuvent être facilement changés et sont disposés de telle manière que la distance entre les axes d'étirage est seulement à peine supérieure au diamètre extérieur de la bague d'étirage. Finally, the cassette-shaped service tools can be easily changed and are arranged in such a way that the distance between the drawing axes is only barely greater than the outside diameter of the drawing ring.

A l'aide du dispositif porte-outils conforme à l'invention, il est possible d'augmenter fortement la capacité d'étirage, étant donné que, simultanément, on peut étirer plusieurs tubes, par exemple trois ou cinq tubes côte à côte. Using the tool holder device according to the invention, it is possible to greatly increase the drawing capacity, since, simultaneously, it is possible to stretch several tubes, for example three or five tubes side by side.

A l'opposé des constitutions connues de machines d'étirage travaillant en continu, grâce à la séparation conforme à l'invention du chariot d'étirage, servant d'organe d'entraînement, et de l'outil de serrage à l'aide de cassettes pour outils, on peut effectuer un étirage multiple qui permet, dans le cas d'une machine d'étirage de 30 t, soit un étirage simple de 30 t, soit un étirage double de deux fois 15 t, soit un étirage quintuple de cinq tubes avec une force respective de traction de 6 t. In contrast to the known constitutions of drawing machines working continuously, thanks to the separation according to the invention of the drawing carriage, serving as a drive member, and the clamping tool using of tool cassettes, it is possible to carry out a multiple drawing which allows, in the case of a drawing machine of 30 t, either a single drawing of 30 t, or a double drawing of twice 15 t, or a five-fold drawing of five tubes with a respective tensile force of 6 t.

Les outils de serrage en forme de cassette, disposes dans le chariot d'étirage, peuvent être aisément remplacés et s'encliquètent par leurs organes d'accouplement dans le chariot d'etirage et sont verrouillés dans cette position. La largeur des cassettes est à peine plus petite que le diametre de la lunette. The cassette-shaped clamping tools, arranged in the drawing carriage, can be easily replaced and snap into the drawing carriage by their coupling members and are locked in this position. The width of the cassettes is barely smaller than the diameter of the bezel.

Il est également possible d'introduire, lors de l'étirage, déjà pour le programme suivant, avec d'autres diamètres et forces de traction, les cassettes correspondantes d'outils de serrage, de sorte que l'on peut effectuer en un temps extrêmement court le changement d'outil et donc la modification d'équipement du banc lors du changement de programme. It is also possible to insert, during stretching, already for the following program, with other diameters and tensile forces, the corresponding cassettes of clamping tools, so that one can perform in one time extremely short tool change and therefore modification of the bench equipment when changing the program.
