Abstract
Description
La présente invention se rapporte à un outil et plus particulièrement à sa partie active qui se présente sous la forme d'une plaquette et est utilisée pour éliminer le cordon de soudure longitudinal des tubes soudés. The present invention relates to a tool and more particularly to its active part which is in the form of a plate and is used to eliminate the longitudinal weld bead from the welded tubes.
On connaît des outils qui comprennent un porte-outil auquel est fixée de façon amovible une plaquette en alliage dur qui forme les surfaces de coupe. Tools are known which include a tool holder to which a hard alloy insert which removably forms the cutting surfaces is fixed.
Pour travailler un tube dans sa direction longitudinale le long d'une génératrice, il est avantageux d'utiliser un outil dont l'arête tranchante présente un profil circulaire, de manière à embrasser une zone non ponctuelle du tube. To work a tube in its longitudinal direction along a generator, it is advantageous to use a tool, the cutting edge of which has a circular profile, so as to embrace a non-point area of the tube.
Parmi les caractéristiques géométriques d'un outil de coupe, l'angle de dépouille supérieur ou angle de pente d'affûtage, est une caractéristique de grande importance. Among the geometric characteristics of a cutting tool, the upper draft angle or angle of sharpening slope is a characteristic of great importance.
Le but de l'invention est de proposer une configura tion-particulierement avantageuse pour un outil destiné à l'élimination du cordon de soudure des tubes. The object of the invention is to propose a particularly advantageous configuration for a tool intended for the elimination of the weld bead from the tubes.
A cet effet, l'outil suivant l'invention est constitué par une plaquette de forme générale prismatique dont les cotés sont concaves et dont les deux bases sont également concaves, de manière à former des arêtes tranchantes curvilignes aux intersections entre les côtés et les bases, la plaquette étant montée sur un porte-outil avec interposi tion d'une contre-plaquette qui posséde une section analogue à celle de la plaquette et qui présente une base plane et l'autre base convexe de façon à s'appuyer contre une base de la plaquette. To this end, the tool according to the invention consists of a generally prismatic plate whose sides are concave and whose two bases are also concave, so as to form curvilinear sharp edges at the intersections between the sides and the bases. , the plate being mounted on a tool holder with the interposition of a counter-plate which has a section similar to that of the plate and which has a flat base and the other convex base so as to bear against a base of the brochure.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre. Au dessin annexé, donné uniquement à titre d'exemple,
la Fig. 1 est. une vue générale d'un outil suivant l'invention placé en position de travail sur un tube
les Fig.2 et 3 sont des vues détaillées des éléments essentiels de l'outil. Other characteristics and advantages of the invention will emerge during the description which follows. In the accompanying drawing, given solely by way of example,
Fig. 1 is. a general view of a tool according to the invention placed in the working position on a tube
Figs 2 and 3 are detailed views of the essential elements of the tool.
Suivant l'exemple d'exécution représenté, une plaquette 11 et une contre-plaquette 12 sont fixées sur un porte-outil 10. According to the embodiment shown, a plate 11 and a counter-plate 12 are fixed to a tool holder 10.
La plaquette 11, qui est également représentée en plan sur la Fig. 3, présente des surfaces latérales concaves 13, le rayon de la concavité étant aussi proche que possible du rayon du tube à travailler, lequel tube est désigné par la référence 20. The plate 11, which is also shown in plan in FIG. 3 has concave lateral surfaces 13, the radius of the concavity being as close as possible to the radius of the tube to be worked, which tube is designated by the reference 20.
Les bases 14 de la plaquette sont elles aussi concaves, de préférence de forme sphérique. Le rayon de cette concavité peut être choisi dans une large gamme? et l'homme de l'art choisira en fonction de l'angle de pente d'affAta- ge moyen, indiqué en ' , qu'on désire obtenir. The bases 14 of the wafer are also concave, preferably of spherical shape. Can the radius of this concavity be chosen from a wide range? and those skilled in the art will choose as a function of the average angle of attack slope, indicated in ', which it is desired to obtain.
Naturellement, la valeur de cet angle varie le long de l'arête tranchante mais cette variation n'est pas excessivement forte. Naturally, the value of this angle varies along the cutting edge, but this variation is not excessively large.
Il est prévu en supplément une contre-plaquette 12 qui présente une base 15 convexe de maniere > épouser la surface concave d'une base 14 de la plaquette. L'autre base 16 est au contraire plane et destinée å s'appuyer sur la face de portée correspondante du porte-outil 10. A counterplate 12 is additionally provided which has a convex base 15 so as to> fit the concave surface of a base 14 of the plate. The other base 16 is on the contrary flat and intended to rest on the corresponding bearing face of the tool holder 10.
La plaquette et la contre-plaquette sont traversées de trous, respectivement 17 et 18, dans lesquels passe le goujon servant à fixer ces éléments au porte-outil. Ce goujon est représenté en 19, tandis qu'on a omis de repré- senter les éléments de commande qui coopèrent avec le goujon pour bloquer et débloquer la plaquette, ces éléments de commande pouvant être choisis parmi différentes formes bien connues. The plate and the counter-plate are traversed by holes, respectively 17 and 18, through which the stud passing for fixing these elements to the tool holder passes. This stud is shown in 19, while omitting to represent the control elements which cooperate with the stud to block and unblock the wafer, these control elements being able to be chosen from various well-known forms.
La configuration proposée par l'invention a l'avantage d'être tres facile à réaliser et présente cependant de grands avantages pour l'exécution du travail mécanique. The configuration proposed by the invention has the advantage of being very easy to carry out and nevertheless has great advantages for the execution of mechanical work.
