La présente invention se propose de fournir une machine fileuse perfectionnée de ce type, qui permette- ;# d'obtenir des profils de poutrelles réguliers malgré d'éven- tuels défauts de planélté des pistes du banc. The present invention proposes to provide an improved spinning machine of this type, which allows; to obtain regular beam profiles despite possible defects in the levelness of the bench tracks.
Un objectif de l'invention est. en particulier de supprimer les bavures en béton qui sont susceptibles de fi former au bas des faces latérales des talons de poutrelles f lorsque la piste comporte des irrégularités. An object of the invention is. in particular to remove the concrete burrs which are liable to form at the bottom of the lateral faces of the heels of beams f when the track has irregularities.
A cet effet, conformément à la présente inven- tion, la machine fileuse du type évoqué plus haut est équipez à llarrière de chaque filière, d'un côté et de l'autre de eh que produit filé, d'un organe d'ébavurage comprenant une de découpe située dans un plan longitudinal en bordure du pro duit et agencée mobile de haut en bas pour venir en appui --Oc tre la piste et suivre le profil de celle-ci en vue de décou per latéralement la partie inférieure du talon du produit ce 9 sidéré. To this end, in accordance with the present invention, the spinning machine of the type mentioned above is equipped at the rear of each die, on one side and on the other as a spun product, with a deburring member. comprising a cutting located in a longitudinal plane at the edge of the product and arranged movable from top to bottom to come into support --Oc be the track and follow the profile thereof in order to cut out laterally the lower part of the heel of the product this flabbergasted 9.
Ainsi ces lames mobiles en appui sur la pis- te quelles que soient les irrégularités de celle-ci, décou pent les bavures de béton susceptibles de couler de part et d'autre des prcduits au-dessous des filières et permettent d'obtenir un profil net et régulier des produits filés.

L'installation de préfabrication visée dans
l'exemple représenté est du type de celle décrite dans la de
mande de brevet n 78.26379 et dans la demande de premier cer
tificat d'addition n 80.13048, qui ont été déposées par las
demanderesse.The prefabrication facility referred to in
the example shown is of the type described in the of
patent application no. 78.26379 and in the application for first cer
addition certificate no 80.13048, which have been filed by las
plaintiff.
Cette installation comprend un banc à plusieurs
pistes, doté à chaque extrémité d'un système de mise en tensc*',
de cables de précontrainte. De part et d'autre des pistes sont. This installation includes a bench with several
tracks, equipped at each end with a tensioning system * ',
of prestressing cables. On both sides of the tracks are.
disposés deux rails tels que 1, s'étendant tout le long du banc. arranged two rails such as 1, extending all along the bench.
Une machine fileuse en continu dont on aper çoit la partie arrière aux figures, peut être amenée à progresser sur ces rails dans le sens de la flèche F pour parcoti-- -- rir la longueur du banc. A continuous spinning machine, the rear part of which can be seen in the figures, can be made to advance on these rails in the direction of the arrow F to parrot the length of the bench.
On se reportera aux demandes de brevet et de certificat d'addition sus-évoquées pour plus de détails sur les divers organes de cette machine : trémie à béton, prémou le vibrant, filières que l'on aperçoit en 3 à l'arrière de la machine, treuil de traction de la machine (laquelle est portée par des roues telles que 4), plaque d'obturation 5 mobile verticalement avec ses moyen de guidage 6 et moyens d'entratnement 12 pour assurer l'interruption des poutrelles aux longueurs désirées, extension 34 de filières situéas à l'ar- rière de la plaque 5 pour réduire les déformations des poutrelles après manoeuvre de la plaque, queues de filières 36, qui prolongent les extensions au niveau des talons de poutrelles en vue d'assurer un guidage prolongé du béton à ce niveau, etc... Reference is made to the patent and addition certificate applications mentioned above for more details on the various organs of this machine: concrete hopper, pre-vibrating vibrator, dies which can be seen in 3 at the rear of the machine, machine traction winch (which is carried by wheels such as 4), shutter plate 5 movable vertically with its guide means 6 and drive means 12 for interrupting the beams at the desired lengths, extension 34 of dies located at the rear of the plate 5 to reduce the deformations of the beams after maneuvering the plate, dies of the dies 36, which extend the extensions at the heels of the beams in order to ensure prolonged guidance concrete at this level, etc ...
Selon la présente invention, des organes d'ébavurage tels que 60, 61, 62...sont portés par les queues de filière 36 à proximité immédiate des extensions 34. According to the present invention, deburring members such as 60, 61, 62 ... are carried by the die tails 36 in the immediate vicinity of the extensions 34.
Chaque organe ébavurage porté par une queue de filière 36 est essentiellement composé de deux lames de dé- coupe 63 et 64 (Figures 2, 3 et 4) qui sont montées coulissantes dans le sens vertical de part et d'autre de la queue de filière 36 dans des rainures en forme de queue d'aronde que comporte cette queue sur chacun de ses flancs. Each deburring member carried by a die tail 36 is essentially composed of two cutting blades 63 and 64 (Figures 2, 3 and 4) which are slidably mounted in the vertical direction on either side of the die tail 36 in grooves in the shape of a dovetail that this tail has on each of its sides.
La profondeur de ces rainures et l'épaisseur des lames de découpe sont prévues de façon à former des faces continues sans surépaisseur au niveau des deux flancs de la queue de filière. The depth of these grooves and the thickness of the cutting blades are provided so as to form continuous faces without additional thickness at the two sides of the die tail.
Les deux lames 63 et 64 sont assujetties en partie haute sur un support 65 en l'exemple de forme tronconique ; cette fixation des lames peut être réalisée gracie à deux rainures longitudinales que comporte ledit support en partie basse, les lames munies d'un perçage étant verrouillées par des goupilles 66. The two blades 63 and 64 are secured in the upper part on a support 65 in the example of frustoconical shape; this fixing of the blades can be carried out thanks to two longitudinal grooves that said support has in the lower part, the blades provided with a bore being locked by pins 66.
Le support 65 percé d'un canal central peut coulisser le long d'une tige verticale 67 solidaire de la queue de filière 36, notamment vissée ou soudée au-dessus de celle-ci. Un ressprt supérieur 68 vient faire pression sur le support 67 de façon à solliciter celui-ci vers le bas. Ce ressort prend appui en partie haute sur un écrou de tarage 69 qui est vissé à l'extrémité supérieure de la tige 67, laquelle est dotée à cet effet d'un filetage. The support 65 pierced with a central channel can slide along a vertical rod 67 secured to the die tail 36, in particular screwed or welded above the latter. An upper spring 68 presses on the support 67 so as to urge the latter downwards. This spring is supported in the upper part on a calibration nut 69 which is screwed to the upper end of the rod 67, which is provided for this purpose with a thread.
En outre, des moyens de graissage sont asso ciés aux lames 63 et 64 pour permettre un coulissement de celles-ci à frottement doux dans leurs rainures. En l'exemple, ces moyens de graissage peuvent comprendre un canal de graissage longitudinal 70 ménagé dans chaque queue de filière 36 et débouchant dans les rainures par des canaux transversaux 71. A son entrée située sur la partie frontale de la queue de filière, le canal 70 est muni d'un embout de type classique pour l'injection d'un liquide ou corps de graissage. In addition, lubrication means are associated with the blades 63 and 64 to allow them to slide with gentle friction in their grooves. In the example, these lubrication means may comprise a longitudinal lubrication channel 70 formed in each die tail 36 and opening into the grooves by transverse channels 71. At its inlet located on the front part of the die tail, the channel 70 is provided with a tip of the conventional type for injecting a liquid or lubricating body.
La figure 5 illustre le fonctionnement des organes d'ébavurage. Quelles que soient les irrégularités des pistes de préfabrication, les lames des divers organes sont maintenues en appui contre les pistes et découpent les bavures qui peuvent se former au niveau des parties basses des talons, par coulée du béton au-dessous des filières. Les deux lames d'un organe donné assurent l'ébavurage des bords contigüs B1 et B2 des talons de deux poutrelles voisines. Figure 5 illustrates the operation of the deburring devices. Whatever the irregularities of the prefabrication tracks, the blades of the various members are held in abutment against the tracks and cut out the burrs which can form at the lower parts of the heels, by pouring the concrete below the dies. The two blades of a given member deburring the contiguous edges B1 and B2 of the heels of two neighboring beams.
Bien entendu, l'invention n' est pas limitée aux termes de la description qui précède, mais en comprend toutes les variantes. Of course, the invention is not limited to the terms of the above description, but includes all variants.
