Description
La présente invention concerne un système permettant de réaliser des bossages annulaires, par gonflement de métal, sur les tuyaux de descente d'eau pluviale, pour préparer la mise en place et éviter le glissement dans leurs colliers de maintien. The present invention relates to a system making it possible to produce annular bosses, by swelling of metal, on the rainwater downpipes, to prepare the installation and prevent slipping in their retaining collars.
Ces bossages annulaires sont traditionnellement fabriqués à partir de profilés demi cylindriques, avec ou sans bords de 2 mm, obtenus par passage de bandes en métal de même nature que les tuyaux de descentes pluviales, entre deux molettes, mâle et femelle, puis enroulées en spirale d'environ 2 m de longueur. These annular bosses are traditionally made from semi-cylindrical profiles, with or without edges of 2 mm, obtained by passing metal strips of the same kind as the downspouts, between two knurls, male and female, then wound in a spiral about 2 m in length.
Le zingueur découpe à la demande deux bagues dans la spirale, les ajuste et les soude sur le tuyau de descente d'eau pluviale, l'une au dessus, l'autre au dessous du collier de maintien. The zinc worker cuts two rings on the spiral on demand, adjusts and seals them on the rainwater down pipe, one above, the other below the clamp.
La pose traditionnelle d'un tuyau de descente d'eau pluviale comprend les phases suivantes
- pose du collier de maintien
- présentation du tuyau dans ce collier
- traçage de l'emplacement des bagues
- dépose du tuyau
- coupe des deux bagues dans la spirale
- ajustage et soudage des deux bagues sur le tuyau
- repose définitive du tuyau dans le collier de maintien.The traditional installation of a rainwater down pipe includes the following phases
- fitting of the support collar
- presentation of the pipe in this necklace
- tracing of the location of the rings
- removal of the hose
- cut of the two rings in the spiral
- adjustment and welding of the two rings on the pipe
- final installation of the pipe in the retaining collar.
Cette pose traditionnelle nécessite un temps de pose d'environ 15 minutes. This traditional pose requires an exposure time of approximately 15 minutes.
Elle consomme de la soudure, de l'acide de décapage et du gaz de soudage. En outre son principe présente des inconvénients : risques de coulures de soudure nuisant à l'esthétique et risques de résidus d'acide de décapage qui, restant enfermés dans le creux des bagues, peuvent provoquer une détérioration prématurée du métal.It consumes welding, pickling acid and welding gas. In addition, its principle has drawbacks: risks of weld seams detrimental to the aesthetics and risks of pickling acid residues which, remaining enclosed in the hollow of the rings, can cause premature deterioration of the metal.
La réalisation des bossages annulaires suivant l'invention, directement sur les tuyaux de descentes d'eau pluviale, permet de remédier à ces inconvénients. The realization of the annular bosses according to the invention, directly on the rainwater downpipes, overcomes these drawbacks.
La pose d'un tuyau de descente d'eau pluviale ne comprend plus que les phases suivantes :
- pose du collier de maintien
- pose définitive du tuyau dans le collier de maintien.The installation of a rainwater downpipe only includes the following phases:
- fitting of the support collar
- final installation of the pipe in the clamp.
Offrant ainsi un gain de temps de pose appréciable, le système de gonflage des tuyaux de descentes d'eau pluviale ne laisse, hors des bossages annulaires, aucune marque, d'où une esthétique parfaite, il ne provoque aucun amincissement du métal, concervant au tuyau toutes ses caractéristiques mécaniques de rigidité et de solidité. Thus offering an appreciable saving in installation time, the inflation system of the rainwater downpipes leaves no marks outside the annular bosses, hence a perfect aesthetic, it does not cause any thinning of the metal, keeping the pipe all its mechanical characteristics of rigidity and solidity.
De plus, le système, selon l'invention, permet de réaliser des bossages annulaires doubles sur des bagues extensibles, qui pourront ensuite être ajustées et soudées sur des chutes de tuyau de descente d'eau pluviale, pour en permettre ainsi la réutilisation, donc minimiser les pertes. In addition, the system according to the invention makes it possible to produce double annular bosses on extensible rings, which can then be adjusted and welded on falls of downpipe for rainwater, thus allowing reuse, therefore minimize losses.
Les bossages annulaires peuvent être réalisés, selon l'invention, sur les tuyaux de descente d'eau pluviale et sur des bagues extensibles, en zinc, cuivre acier inoxydable et tous métaux ferreux ou non. According to the invention, the annular bosses can be produced on the rainwater downpipes and on expandable rings, made of zinc, copper, stainless steel and all ferrous metals or not.

Le dispositif selon l'invention est constitue
- D'une matrice en acier à l'intérieur de laquelle sont reproduits en creux les bossages annulaires (15), en deux parties--l'une, inférieure (1), immobilisée sur une table de presse (8) -- l'autre supérieure, mobile (2), guidée par les axes (14) sur l'inférieure (1), est reliée au vérin de la presse (9) lui même animé d'un mouve ment vertical alterné : vers le haut pour permettre l'ouverture de la matrice, l'intro- duction du tuyau à gonfler ou le dégagement du tuyau après gonflage, vers le bas pour fermer la matrice avant le gonflage, du tuyau.The device according to the invention is constituted
- A steel matrix inside which are hollowed out the annular bosses (15), in two parts - one, lower (1), immobilized on a press table (8) - l 'other upper, mobile (2), guided by the axes (14) on the lower (1), is connected to the press cylinder (9) itself animated alternately vertical movement: upwards to allow opening the die, inserting the hose to be inflated or releasing the hose after inflation, down to close the matrix before inflating the hose.
- D'un vérin hydraulique à double effet, dont le cylindre (3) est relié par des guides rainurés (15) à la demi matrice fixe (1), l'immobilisant latéralement mais lui laissant un mouvement vertical, et dont le piston (4) sur lequel est vissé un axe en acier (5) terminé par un cône métallique (6), permet un mouvement de tirage. - A double-acting hydraulic cylinder, whose cylinder (3) is connected by grooved guides (15) to the fixed half-matrix (1), immobilizing it laterally but leaving it in a vertical movement, and whose piston ( 4) on which is screwed a steel pin (5) terminated by a metal cone (6), allows a pulling movement.
- D'un manchon cylindrique (7) en élastomère de. polyuréthane compact ajusté sur l'axe (5), d'un diamètre extérieur légèrement inférieur à ceux du tuyau ou à la bague extensible à gonfler, immobilisé latéralement entre le cône (6) et une rondelle (10)
Après introduction du tuyau ou de la bague extensible à gonfler et abaissement de la demi matrice supérieure (2), sous l'action du vérin de tirage, le manchon en élastomère (11), comprimé entre le cône (6) et la rondelle (10), monte en pression, épousant la forme de la matrice, déformant le tuyau ou la bague extensible sur lesquels sont reproduites les formes exactes de la matrice (16-17). - A cylindrical sleeve (7) made of elastomer. compact polyurethane adjusted on the axis (5), with an outside diameter slightly smaller than those of the hose or the expandable ring to be inflated, immobilized laterally between the cone (6) and a washer (10)
After insertion of the hose or the expandable ring to be inflated and lowering of the upper half-matrix (2), under the action of the pulling cylinder, the elastomer sleeve (11), compressed between the cone (6) and the washer ( 10), increases in pressure, conforming to the shape of the matrix, deforming the pipe or the extensible ring on which the exact forms of the matrix are reproduced (16-17).
Lors de l'abaissement de la demi matrice (2) l'ensemble vérin de tirage est sollicité vers le bas, des ressorts de rappel (12) permettent son autocentrage et son relevage automatique lors du relevage de la demi matrice (2). When lowering the half matrix (2) the pulling cylinder assembly is biased downward, return springs (12) allow its self-centering and automatic lifting when raising the half matrix (2).
Plusieurs jeux interchangeables d'ensembles matrice - axe et cône - manchon élastomère - permettent le gonflage de différents diamètres de tuyaux et de bagues extensibles.
