Description

La présente invention est relative à une presse portative pour soudure à chaud, notamment de joints, par vulcanisation. The present invention relates to a portable press for hot welding, in particular of joints, by vulcanization.

Les solutions traditionnellement utilisées pour solidariser entre elles les extrémités d'un joint sont - le collage, en utilisant des colles spéciales, telles
que les cyano-acrylates, ou - le soudage à chaud en atelier, à l'aide d'installations
lourdes.The solutions traditionally used to join together the ends of a joint are - bonding, using special glues, such
than cyanoacrylates, or - hot welding in the workshop, using installations
heavy.

Toutefois, les solutions de l'Art antérieur ne permettent pas de résoudre de façon satisfaisante certains problèmes liés à la solidarisation des extrémités opposées des joints entre elles, notamment :
- en ce qui concerne le collage, les colles employées ne
sont pas compatibles avec des températures élevées ni
avec certains types de solvants ; en outre, les joints
ainsi traités se détériorent très rapidement quand ils
sont utilisés dans des conditions dynamiques, à cause
des efforts auxquels ils sont souris
- en ce qui oenoerne la soudure à chaud, par vulcanisation, à l'aide
d'installations louais, en usine, cette solution présente l'in
oenvénient d'entraîner des attentes très longs par rapport aux
besoins sur le chantier.However, the solutions of the prior art do not make it possible to satisfactorily resolve certain problems linked to the joining of the opposite ends of the joints together, in particular:
- with regard to gluing, the glues used do not
are not compatible with high temperatures nor
with certain types of solvents; in addition, the seals
well treated deteriorate very quickly when they
are used in dynamic conditions, because
efforts to which they are mice
- with regard to hot welding, by vulcanization, using
of louais installations, in factory, this solution presents the in
disadvantage of causing very long waits compared to
needs on site.

La présente invention a en conséquence pour but de pourvoir à un dispositif de soudage, en particulier de
joints, par vulcanisation, qui repond mieux aux nécessités de la pratique que les dispositifs visant au mEm.e but antérieurement connus, notamment en ce qu'il allie aux avantages de la soudure à chaud, par vulcnnisation - qui consistent essentiellement à retrouver à l'endroit de la soudure les mêmes caractéristiques physiques et chimiques que sur le reste du joint - la souplesse d'une intervention sur chantier à la demande, qui est propre à l'emploi de colles.The present invention therefore aims to provide a welding device, in particular to
joints, by vulcanization, which responds better to the needs of the practice than the devices aiming at the mEm.e previously known goal, in particular in that it combines the advantages of hot welding, by vulcnnisation - which consist essentially of finding in the he location of the weld has the same physical and chemical characteristics as on the rest of the joint - the flexibility of an intervention on site on demand, which is specific to the use of adhesives.

La présente invention a pour objet une presse portative pour soudure à chaud, notamment de joints, par vulcanisation, caractérisée en ce qu'elle se présente sous la forme d'une pince et comprend deux branches, dont l'une est mobile par rapport à l'autre par l'intermédiaire d'articulations à genouillère, en ce que chacune desdites branches comporte à l'une de ses extrémités une machoire portant un plateau de soudure par vulcanisation à chaud, et en ce que les plateaux de soudure, qui sont disposés en correspondance l'un de l'autre, et qui sont destinés à se faire face lors de l'opération de soudure, présentent sur leur face extérieure une pluralité de profils en creux correspondant à différents profils de joints susceptibles d'être soudés par vulcanisation dans ladite presse portative. The present invention relates to a portable press for hot welding, in particular of joints, by vulcanization, characterized in that it is in the form of a clamp and comprises two branches, one of which is movable relative to the other by means of toggle joints, in that each of said branches comprises at one of its ends a jaw carrying a weld plate by hot vulcanization, and in that the weld plates, which are arranged in correspondence with one another, and which are intended to face each other during the welding operation, have on their outer face a plurality of hollow profiles corresponding to different profiles of joints capable of being welded by vulcanization in said portable press.

Selon un mode de réalisation avantageux de la presse portative conforme à l'invention, le plateau de soudure monté dans la mâchoire fixe est pourvu d'ergots de centrage et de maintien du joint à souder. According to an advantageous embodiment of the portable press according to the invention, the welding plate mounted in the fixed jaw is provided with lugs for centering and holding the joint to be welded.

Selon une disposition avantageuse de ce mode de réalisation, chaque ergot est placé en correspondance de chacune des extrémités des différentes dents de séparation entre les différents profils concaves ménagés sur la face extérieure du plateau mont dans la mâchoire fixe.  According to an advantageous arrangement of this embodiment, each lug is placed in correspondence of each of the ends of the different separation teeth between the different concave profiles formed on the external face of the plate mounted in the fixed jaw.

Selon un mode de réalisation avantageux de la presse portative conforme à l'invention, les différents profils concaves ménagés sur la surface extérieure du plateau de soudure monté dans la mâchoire fixe présentent une longueur proportionnelle à la profondeur, en sorte que ledit plateau se présente sous la forme d'un triangle tronqué, délimite latéralement par lesdits ergots de centrage et de maintien. According to an advantageous embodiment of the portable press according to the invention, the various concave profiles formed on the external surface of the welding plate mounted in the fixed jaw have a length proportional to the depth, so that said plate is present under the shape of a truncated triangle, delimited laterally by said centering and holding lugs.

Il doit être bien entendu, toutefois, que ces dessins et les parties descriptives correspondantes, sont donnés uniquement à titre d'illustration de l'objet de l'invention, dont ils ne constituent en aucune manière une limitation. It should be understood, however, that these drawings and the corresponding descriptive parts, are given solely by way of illustration of the subject of the invention, of which they do not in any way constitute a limitation.

La presse portative pour soudure à chaud, notamment d'un joint, par vulcanisation, conforme à l'invention, se présente sous la forme d'une pince comprenant deux bran ches, dont l'une est mobilc par rapport à l'autre par l'intermédiaire d'une pluralité d'articulations à genouillère. The portable press for hot welding, in particular of a joint, by vulcanization, in accordance with the invention, is in the form of a clamp comprising two branches, one of which is movable relative to the other by through a plurality of toggle joints.

Chaque branche comporte, à l'une de ses extrémités, une mâchoire,1 et 2 respectivement, entre lesquelles peut être placé un joint (non représenté) dont les extrémités doivent être soudées ensemble par vulcanisation d'une dissolution de caoutchouc appliquée aux extrémités dudit joint.Each branch has, at one of its ends, a jaw, 1 and 2 respectively, between which can be placed a joint (not shown) whose ends must be welded together by vulcanization of a rubber solution applied to the ends of said attached.

La mâchoire fixe 1 fait saillie à partir de l'extrémité du bâti 3 de la presse portative correspondant à la base d'appui de ce bâti 3 et est réalisée en une seule pièce avec celui-ci, tandis que la mâchoire mobile 2, sensiblement en forme de L inversé à segments égaux,est articulée, à l'aide d'une articulation à genouillère 4, par rapport à l'extrémité du bâti 3 oppose e à l'extrémité dont est solidaire ladite mâchoire fixe 1. The fixed jaw 1 protrudes from the end of the frame 3 of the portable press corresponding to the support base of this frame 3 and is produced in one piece with it, while the movable jaw 2, substantially in the shape of an inverted L with equal segments, is articulated, by means of a toggle joint 4, relative to the end of the frame 3 opposite to the end of which said fixed jaw 1 is integral.

En position de repos cette mâchoire 2 est tenue séparée de la mâchoire 1 à l'aide d'un ressort de traction 5 tendu entre une deuxième articulation à genouillère 6 prévue dans l'extrémité de la mâchoire supérieure 2, placée du même côté que la première articulation à genouillère 4, et l'axe 7, ce dernier se trouvant dans la partie médiane supérieure du bâti 3. In the rest position this jaw 2 is kept separate from the jaw 1 by means of a tension spring 5 stretched between a second toggle joint 6 provided in the end of the upper jaw 2, placed on the same side as the first toggle joint 4, and the axis 7, the latter being in the upper middle part of the frame 3.

En correspondance de la deuxième articulation à genouillère 6, ladite mâchoire supérieure 2 s'articule avec une extrémité d'un levier 8 : une troisième articulation à genouillère 9, placée à une distance de la deuxième articulation 6, qui est fonction de la tension élastique du ressort de traction 5, relie entre eux ledit levier 8 et une biellette 10 dont l'autre extrémité est également articulée, à l'aide d'une quatrième articulation à genouillère 11, disposée en correspondance de l'extrémité du bâti 3 qui est alignée avec la première articulation à genouillère 4. In correspondence with the second knee joint 6, said upper jaw 2 is articulated with one end of a lever 8: a third knee joint 9, placed at a distance from the second joint 6, which is a function of the elastic tension of the tension spring 5, connects said lever 8 and a connecting rod 10, the other end of which is also articulated, by means of a fourth toggle joint 11, arranged in correspondence with the end of the frame 3 which is aligned with the first toggle joint 4.

Chaque articulation à genouillère comporte les éléments suivants, qui sont décrits par rapport à la seule articulation 11 : un axe lla, deux rondelles llb, deux bagues lic et une goupille élastique lld. Each toggle joint comprises the following elements, which are described with respect to the single joint 11: an axis lla, two washers llb, two rings lic and an elastic pin lld.

Conformément à l'invention, un plateau de soudure 15 est monté dans la mâchoire fixe 1, de même qu'un autre plateau de soudure 16 est monté dans la mâchoire mobile 2 : c'est précisément entre ces plateaux 15 et 16 que sont serrées les extrémités dudit joint torique à souder et c'est par leur intermédiaire que se fait l'apport de la chaleur nécessaire pour la vulcanisation d'une dissolution de caoutchouc appliquée sur les extrémités dudit joint. A cet effet, le plateau 15 monté dans la machoire fixe 1 est isolé thermiquement par rapport à cette dernière et au bâti 3 à l'aide de deux plaques isolantes 17a et 18a, respectivement.De façon similaire, le plateau 16 monté dans la mâchoire mobile 2 est isolé thermiquement,par rapport aux deux segments du L constituant cette mâchoire mobile 2,à l'aide de deux autres plaques isolantes 17b et 186.  According to the invention, a welding plate 15 is mounted in the fixed jaw 1, as well as another welding plate 16 is mounted in the movable jaw 2: it is precisely between these plates 15 and 16 that are clamped. the ends of said O-ring to be welded and it is through them that the heat necessary for the vulcanization of a rubber solution applied to the ends of said seal is supplied. To this end, the plate 15 mounted in the fixed jaw 1 is thermally insulated with respect to the latter and to the frame 3 by means of two insulating plates 17a and 18a, respectively. Similarly, the plate 16 mounted in the jaw mobile 2 is thermally insulated, with respect to the two segments of the L constituting this mobile jaw 2, using two other insulating plates 17b and 186.

Dans chacun des plateaux de soudure 15 et 16 est ménagé un canal 22a et 22b, respectivement, (cf. figure 3) chaque canal 22a et 22b étant destiné à recevoir un élément chauffant du plateau correspondant, notamment une cartouche chauffante 23 et 24, respectivement, de puissance appropriée et avantageusement constituée par une résistance électrique blindée, spécifiquement utilisé pour chauffer une masse, telle que la masse desdits plateaux de soudure 15 et 16 de la presse portative conforme à l'invention. In each of the welding plates 15 and 16 is formed a channel 22a and 22b, respectively, (cf. FIG. 3) each channel 22a and 22b being intended to receive a heating element of the corresponding plate, in particular a heating cartridge 23 and 24, respectively , of appropriate power and advantageously constituted by an armored electrical resistance, specifically used to heat a mass, such as the mass of said welding plates 15 and 16 of the portable press according to the invention.

En particulier, la cartouche 24 qui chauffe le plateau de soudure 16 est protégée contre les flexions, en sorte qu'elle peut suivre sans danger les mouvements de rotation de la mâchoire mobile 2 autour de la première articulation à genouillère 4, sous l'action du levier 8. In particular, the cartridge 24 which heats the welding plate 16 is protected against bending, so that it can safely follow the rotational movements of the movable jaw 2 around the first toggle joint 4, under the action lever 8.

Le contrôle de la température de vulcanisation est obtenu à l'aide d'un thermostat 34 qui coopère avec un voyant lumineux 37, la mise sous tension des résistances électriques blindées 23 et 24 se faisant à l'aide d'un interrupteur 36 placé sur la face arrière du bâti 3 de la presse portative. Control of the vulcanization temperature is obtained using a thermostat 34 which cooperates with an indicator light 37, the powering of the shielded electrical resistors 23 and 24 being done using a switch 36 placed on the rear face of the frame 3 of the portable press.

Sur la surface extérieure des deux plateaux de soudure-15 et 16, destinés à se faire face lors de l'opération de soudure, est ménagée une pluralité de profils concaves, en particulier semi cylindriques 25, 26, 27, 28 29 et 30,parallèles entre eux et de diamètre différent, séparés les uns des autres par des dents 31 de largeur appropriée : les profils de même diamètre ménagés dans les deux plateaux 15 et 16 se correspondent entre eux et délimitent des canaux 32 quand lesdits deux plateaux 15 et .16 sont appliqués l'un contre l'autre sous l'action du levier 8 : dans chaque canal du type du canal 32 est serré un joint torique dont les deux extrémités doivent être soudées. On the outer surface of the two welding plates -15 and 16, intended to face each other during the welding operation, a plurality of concave profiles, in particular semi-cylindrical 25, 26, 27, 28 29 and 30, are provided, parallel to each other and of different diameter, separated from each other by teeth 31 of appropriate width: the profiles of the same diameter formed in the two plates 15 and 16 correspond to each other and delimit channels 32 when said two plates 15 and. 16 are applied against each other under the action of the lever 8: in each channel of the type of channel 32 is tightened an O-ring whose two ends must be welded.

De toutes façons, la forme des profils concaves ménagés dans chacun des deux plateaux de soudure 15 et 16 peut être a priori quelconque pour s adapter aux différentes formes de joints. In any case, the shape of the concave profiles formed in each of the two welding plates 15 and 16 can be a priori arbitrary in order to adapt to the different shapes of seals.

A cet effet ces plateaux 15 et 16 sont interchangeables en fonction de la forme et des#dimensions -desdits profils, assurant ainsi une. souplesse d'emploi d'extrême utilité pratique. For this purpose these plates 15 and 16 are interchangeable according to the shape and # dimensions -des Said profiles, thus ensuring a. flexibility of use of great practical utility.

Avantageusement, le plateau de soudure 15, monté sur la mâchoire fixe 1, est pourvu d'ergots 33 de -centrage et de maintien du joint à souder : en particulier, chaque ergot 33 est disposé en correspondance de chacune des extrémités des différentes dents 31 de séparation entre les profils concaves 25 à 30 ménagés sur la face extérieure dudit plateau 15. Advantageously, the welding plate 15, mounted on the fixed jaw 1, is provided with lugs 33 for -centring and for holding the weld joint: in particular, each lug 33 is arranged in correspondence with each of the ends of the different teeth 31 of separation between the concave profiles 25 to 30 formed on the external face of said plate 15.

Etant donné que dans la majorité des cas rencontrés dans la pratique il y a une relation de pro portionnalité entre le diamètre intérieur d'un joint, ou sa loxigueurdéveloppée, et l'épaisseur du même joint, il s'est avéré avantageux de réaliser les différents profils concaves ménagés sur la surface extérieure du plateau 15, monté dans la mâchoire fixe 1, de façon à respecter la
relation ci-dessus indiquée, en sorte que ledit plateau 15
se présente sous la forme d'un triangle tronqué délimité
latéralement par lesdits ergots de centrage et de maintien
33.Since in the majority of cases encountered in practice there is a proportionality relationship between the internal diameter of a joint, or its developed thickness, and the thickness of the same joint, it has proved advantageous to carry out the different concave profiles formed on the outer surface of the plate 15, mounted in the fixed jaw 1, so as to respect the
relationship indicated above, so that said plate 15
is in the form of a delimited truncated triangle
laterally by said centering and retaining pins
33.

La solidarisation d'un plateau de soudure avec la
mâchoire dans laquelle il est monté est réalisée à l'aide
d'une pluralité de vis de serrage 19a et 19b pour les
paxties mobile et fixe, respectivement.The joining of a welding plate with the
jaw in which it is mounted is made using
a plurality of clamping screws 19a and 19b for the
mobile and fixed paxties, respectively.

Pour ne pas écraser le joint à souder, lors du
serrage,les vis l-9a solidarisant la mâchoire mobile 2 au
plateau correspondant 16 coopèrent avec des ressorts qui
assurent un réglage de l'effort de serrage entre les deux
mâchoires 1 et 2 de la presse portative : avantageusement
ces ressorts sont constitués par des rondelles élastiques 20a tenues en position dans des logements ménagés à cet effet
dans ledit plateau 161 autour de chaque vis de serrage 19a.To avoid crushing the welded joint, when
tightening, the screws l-9a securing the movable jaw 2 to
corresponding plate 16 cooperate with springs which
adjust the clamping force between the two
jaws 1 and 2 of the portable press: advantageously
these springs are constituted by elastic washers 20a held in position in housings provided for this purpose
in said plate 161 around each clamping screw 19a.

Pour mieux distribuer les efforts de serrage et,
en même temps, pour ne pas nuire l'intégrité de la plaque
isolante 17b disposée parallèlement au plateau de soudure mobile 16, ce dernier est séparé de ladite plaque 17b par
une tôle 21 de répartition des efforts, des rondelles 20b
étant interposées entre cette tôle 21 et ce plateau 16 autour des
vis de serrage 19a.To better distribute the clamping forces and,
at the same time, so as not to damage the integrity of the plate
insulator 17b arranged parallel to the movable welding plate 16, the latter is separated from said plate 17b by
a sheet 21 for distributing the forces, washers 20b
being interposed between this sheet 21 and this plate 16 around the
clamping screw 19a.

Le serrage entre les deux mâchoires 1 et 2 est rendu possible à l'aide d'une tige de manoeuvre tubulaire 12, tenue en position par introduction dans un logement ménagé à cet effet dans la face arrière du bâti 3,et à l'aide d'une goupille élastique 14, laquelle tige 12 coopère avec le levier 8, en sorte que l'actionnement des deux mâchoires let2 se fait manuellement et aisément de la part de l'opérateur sur le chantier, à la demande. Cette tige de manoeuvre tubulaire 12 est traversée par les câbles électriques d'alimentation du circuit contenu à l'intérieur du bâti 3 de la presse portative : à cet effet l'extrémité libre de cette tige 12 est pourvue d'un presse-étoupe 39. The clamping between the two jaws 1 and 2 is made possible using a tubular operating rod 12, held in position by insertion into a housing provided for this purpose in the rear face of the frame 3, and using an elastic pin 14, which rod 12 cooperates with the lever 8, so that the actuation of the two jaws let2 is done manually and easily by the operator on site, on request. This tubular operating rod 12 is crossed by the electric cables for supplying the circuit contained inside the frame 3 of the portable press: for this purpose the free end of this rod 12 is provided with a cable gland 39 .

Pour des raisons de sécurité d'emploi, ladite tige de manoeuvre 12 est enveloppée par une gaine, ou manche, isolante 13. For reasons of safety of use, said operating rod 12 is wrapped by an insulating sheath, or sleeve 13.

L'accès aux connexions électriques se fait à travers une ouverture ménagée dans la base d'appui dudit bâti 3 et fermée par un couvercle 38. Access to the electrical connections is made through an opening made in the support base of said frame 3 and closed by a cover 38.

Ainsi que cela ressort de ce qui précède, l'invention ne se limite nullement à ceux de ses modes de réalisation et d'application qui viennent d'être décrits de façon plus explicite ; elle en embrasse au contraire toutes les variantes qui peuvent venir à l'esprit du technicien en la matière, sans s'écarter du cadre, ni de la portée, de la présente invention.  As is apparent from the above, the invention is in no way limited to those of its embodiments and of application which have just been described more explicitly; on the contrary, it embraces all the variants which may come to the mind of the technician in the matter, without departing from the framework, or the scope, of the present invention.
