Abstract

The fount has two identical matrices each with a hollow cavity which extends laterally on each edge through a matrix junction surface. The surface forms teeth (3) and interstices (4) having combined forms such that the teeth and the interstices imbricate one another from one matrix to another during mutual connection of the matrices. The teeth and the interstices placed on a side of a median longitudinal plane of the cavity align respectively, for each matrix, on the interstices and the teeth placed on the other side of the longitudinal plane.

Description

L'invention concerne un jeu de deux matrices destinées à équiper une presse à rétreindre et/ou à sertir une pièce tubulaire.The invention relates to a set of two dies intended to equip a press to shrink and / or to crimp a tubular piece.

Il est connu de sertir un embout ou un raccord disposé dans un tuyau, ou encore de sertir un câble, au moyen d'une bague métallique extérieure qui est généralement rétreinte à froid.It is known to crimp a tip or a fitting disposed in a pipe, or to crimp a cable, by means of an outer metal ring which is generally cold-shrink.

L'embout est généralement pourvu de bosselages périphériques, qui viennent ainsi s'ancrer dans la matière constitutive du tuyau par serrage de ladite bague extérieure. Il est connu aussi dans le sertissage de former lesdits bosselages au moment du serrage sur la bague elle-même.The tip is usually provided with peripheral bosses, which are thus anchored in the constituent material of the pipe by clamping said outer ring. It is also known in crimping to form said bossings at the time of tightening on the ring itself.

Pour rétreindre la bague, on peut utiliser des outils munis de mors, ou encore de préférence une presse hydraulique manuelle ou non qui comporte une tête dans laquelle on dispose deux matrices en regard, formant une empreinte en creux, l'une étant immobilisée tandis que l'autre, montée mobile, est sollicitée par le vérin hydraulique de la presse.To shrink the ring, it is possible to use tools provided with jaws, or preferably a manual or non-manual hydraulic press which comprises a head in which two opposite matrices are arranged, forming a recessed impression, one being immobilized while the other, mounted mobile, is solicited by the hydraulic cylinder of the press.

Pour effectuer un sertissage au moyen d'une bague comme mentionné ci-avant, les deux matrices resserrées l'une sur l'autre forment une surface par exemple sensiblement tubulaire cylindrique ou polygonale, aux bosselages près, mais qui est resserrée par rapport à la forme cylindrique initiale de la bague.To effect a crimping by means of a ring as mentioned above, the two matrices tightened one on the other form a surface, for example substantially tubular cylindrical or polygonal, with the bumps close, but which is tightened compared to the initial cylindrical shape of the ring.

On connaît divers dispositifs dont les deux matrices sont pourvues d'éléments et d'espaces qui s'imbriquent les uns dans les autres pour former une empreinte lorsqu'elles sont pressées l'une sur l'autre, comme par exemple les dispositifs décrits dans les documents US-3,055,412-A , US-3,085,313-A , US-2,692,422-A ou encore EP-0 620 057-A au nom du même déposant.Various devices are known in which the two matrices are provided with elements and spaces which interlock with one another to form an impression when they are pressed together, such as for example the devices described in FIG. the documents US-3055412-A , US-3085313-A , US-2692422-A or EP-0 620 057-A in the name of the same applicant.

Dans tous les dispositifs précités, les éléments et les espaces de chaque matrice sont alignés transversalement, un élément ou réciproquement un espace d'un côté du plan longitudinal médian de la matrice s'alignant avec un élément ou réciproquement un espace disposé de l'autre côté dudit plan.In all the aforementioned devices, the elements and spaces of each matrix are aligned transversely, an element or reciprocally a space on one side of the median longitudinal plane of the matrix aligning with an element or conversely a space disposed of the other side of said plane.

Dans le document précité EP-0 620 057-A , on décrit plus particulièrement un jeu avantageux de deux matrices destinées à équiper une presse à rétreindre et/ou à sertir une pièce tubulaire métallique, les matrices présentant chacune une empreinte en creux qui se prolonge latéralement sur chaque bord par une surface de jonction des matrices, formant une pluralité de dents et d'interstices ayant des formes conjuguées de telle sorte que lesdites dents et lesdits interstices sont prévus pour s'imbriquer les uns dans les autres d'une matrice à l'autre lors du rapprochement mutuel des deux matrices, réalisé par la presse.In the aforementioned document EP-0 620 057-A , an advantageous set of two dies intended to equip a press for shrinking and / or crimping a metal tubular part is described more particularly, the dies each having a hollow recess which is extended laterally on each edge by a junction surface of the dies. forming a plurality of teeth and interstices having conjugate shapes such that said teeth and said interstices are provided to interlock into each other from one die to the other when the two dies are brought together, made by the press.

Dans un tel dispositif, comme déjà dit, les dents et les interstices de chaque matrice sont alignés transversalement, ce qui permet de faciliter la fabrication par usinage.In such a device, as already said, the teeth and the interstices of each matrix are aligned transversely, which facilitates the manufacture by machining.

Toutefois, si dans les trois premiers documents cités, les deux matrices sont distinctes et nécessitent non seulement une fabrication spécifique pour chacune d'entre elle mais aussi l'impossibilité de les intervertir, par contre, le EP-0 620 057-A décrit un mode de réalisation dans lequel les deux matrices sont identiques. Cependant dans ce cas les matrices sont destinées à se présenter de face, mais retournées l'une par rapport à l'autre, de manière que les dents de l'une s'ajustent dans les interstices de l'autre.However, if in the first three documents cited, the two matrices are distinct and require not only a specific manufacture for each of them but also the impossibility to interchange them, on the other hand, the EP-0 620 057-A describes an embodiment in which the two matrices are identical. However, in this case the dies are intended to be face, but returned with respect to each other, so that the teeth of one fit into the interstices of the other.

Si une telle disposition permet de faciliter la fabrication par usinage comme déjà dit, du fait dudit alignement des dents des matrices et surtout de pouvoir utiliser deux matrices strictement identiques, il y a un inconvénient à devoir chercher le bon sens de présentation des matrices l'une par rapport à l'autre.If such an arrangement makes it easier to manufacture by machining as already said, because of said alignment of the teeth of the dies and especially to be able to use two strictly identical dies, there is a disadvantage in having to look for the good sense of presentation of the dies. one compared to the other.

En outre, l'avantage de fabrication précité n'a d'intérêt que pour un usinage alors qu'avec un procédé de fabrication par moulage, cet intérêt disparaît.In addition, the manufacturing advantage mentioned above is only relevant for machining whereas with a molding manufacturing process, this interest disappears.

C'est pourquoi les inventeurs ont imaginé un jeu de deux matrices qui sont à la fois identiques et qui peuvent être disposées dans n'importe quel sens l'une par rapport à l'autre, c'est-à-dire que pour chaque matrice, les dents et les interstices disposés d'un côté du plan longitudinal médian de l'empreinte, par rapport aux dents et interstices disposés de l'autre côté dudit plan longitudinal, se correspondent après une rotation d'un angle plat autour de l'axe défini par l'intersection dudit plan longitudinal et d'un plan transversal médian de l'empreinte.This is why the inventors have devised a set of two matrices which are both identical and which can be arranged in any sense with respect to each other, that is to say that for each matrix, the teeth and the interstices arranged on one side of the median longitudinal plane of the impression, with respect to the teeth and interstices disposed on the other side of said longitudinal plane, correspond after a rotation of a flat angle around the axis defined by the intersection of said longitudinal plane and a median transverse plane of the footprint.

A cet effet, les inventeurs proposent un jeu de matrices du type précité à propos du document EP-0 620 057 et conformément au préambule de la revendication 1, mais qui est remarquable en ce que pour chaque matrice, les dents et respectivement les interstices disposés d'un côté du plan longitudinal médian de l'empreinte, s'alignent sur les interstices et respectivement les dents disposés de l'autre côté dudit plan longitudinal.For this purpose, the inventors propose a set of dies of the aforementioned type with reference to the document EP-0 620 057 and in accordance with the preamble of claim 1, but which is remarkable in that for each matrix, the teeth and the interstices respectively arranged on one side of the median longitudinal plane of the impression, align with the interstices and the teeth respectively. arranged on the other side of said longitudinal plane.

Par exemple, chaque extrémité transversale de chaque matrice commence de manière identique, d'un côté du plan longitudinal médian de l'empreinte, par au moins une partie de dent et/ou au moins une partie d'interstice, et, de l'autre côté dudit plan, réciproquement et inversement, par au moins une partie d'interstice et/ou au moins une partie de dent.For example, each transverse end of each die begins identically, on one side of the median longitudinal plane of the impression, with at least one tooth portion and / or at least one interstice portion, and another side of said plane, reciprocally and vice versa, by at least a gap portion and / or at least a tooth portion.

Selon un mode de réalisation, chaque matrice est fabriquée d'une seule pièce par moulage.According to one embodiment, each matrix is manufactured in one piece by molding.

Selon un mode de réalisation non obligatoire, l'empreinte en creux de chaque matrice forme une partie uniforme de cylindre ou de polygone pour constituer une empreinte complète sensiblement tubulaire uniforme cylindrique ou respectivement polygonale.According to a non-mandatory embodiment, the indentation of each matrix forms a uniform portion of a cylinder or polygon to form a cylindrical or polygonal uniformly substantially cylindrical complete impression.

Selon un autre mode particulier, l'empreinte en creux de chaque matrice comprend au moins deux parties de cylindres concentriques alternées dans le sens longitudinal et séparées par au moins une saillie radiale orientée vers l'intérieur de l'empreinte.According to another particular embodiment, the indentation of each die comprises at least two concentrically reciprocating cylindrical portions in the longitudinal direction and separated by at least one radial projection oriented towards the inside of the imprint.

Il est clair que si l'invention concerne un jeu de deux matrices, elle concerne aussi bien entendu une seule matrice destinée à coopérer avec une autre matrice identique afin de former un jeu de deux matrices tel que défini ci-avant.It is clear that if the invention relates to a set of two matrices, it also concerns of course a single matrix intended to cooperate with another identical matrix to form a set of two matrices as defined above.

L'invention sera bien comprise à la lecture de la description qui va suivre et qui se réfère aux dessins annexés dans lesquels :

  • les figures 1 et 2 montrent en perspective une matrice selon l'invention dans deux positions différentes (ou encore deux matrices distinctes mais identiques, destinées à coopérer entre elles en formant une paire),
  • la figure 3 montre la matrice des figures 1 et 2 en élévation, vue dans la direction longitudinale de son empreinte en creux,
  • la figure 4 est une coupe selon IV-IV de la figure 3,
  • la figure 5 montre en élévation deux matrices telles que représentées sur les figures 1 à 4, imbriquées l'une dans l'autre,
  • la figure 6 est une coupe selon VI-VI de la figure 5,
  • les figures 7, 8 et 9 correspondent aux figures respectivement 2, 4 et 6 selon un mode de réalisation légèrement différent.
The invention will be better understood on reading the description which follows and which refers to the appended drawings in which:
  • Figures 1 and 2 show in perspective a matrix according to the invention in two different positions (or two separate but identical matrices, intended to cooperate with each other forming a pair),
  • FIG. 3 shows the matrix of FIGS. 1 and 2 in elevation, seen in the longitudinal direction of its indentation,
  • FIG. 4 is a section on IV-IV of FIG. 3,
  • FIG. 5 shows in elevation two matrices as represented in FIGS. 1 to 4, nested one inside the other,
  • FIG. 6 is a section along VI-VI of FIG. 5,
  • Figures 7, 8 and 9 correspond to Figures 2, 4 and 6 respectively according to a slightly different embodiment.

Sur les figures 1 à 6, on peut voir une matrice 1 destinée à coopérer avec une matrice identique afin de constituer un jeu de deux matrices 1, 1' comme représenté sur la figure 5, lesdites matrices étant destinées à équiper une presse à rétreindre et/ou à sertir une pièce tubulaire. Les matrices 1, 1' sont avantageusement obtenues d'une seule pièce, par moulage.In FIGS. 1 to 6, there can be seen a matrix 1 intended to cooperate with an identical matrix in order to constitute a set of two matrices 1, 1 'as represented in Figure 5, said matrices being intended to equip a press to shrink and / or crimp a tubular piece. The dies 1, 1 'are advantageously obtained in one piece, by molding.

La matrice 1 présente une empreinte en creux 2 sous la forme dans l'exemple des figures 1 à 6, sensiblement d'une partie de cylindre.The matrix 1 has an indentation 2 in the form in the example of Figures 1 to 6, substantially a cylinder portion.

L'empreinte 2 de la matrice se prolonge latéralement sur chaque bord par une surface de jonction formant une pluralité de dents 3 et d'interstices 4 (figures 1, 2 et 4) de formes conjuguées.The impression 2 of the matrix is extended laterally on each edge by a junction surface forming a plurality of teeth 3 and interstices 4 (FIGS. 1, 2 and 4) of conjugate shapes.

Sur la figure 5 qui représente, comme déjà dit, deux matrices 1, 1' imbriquées l'une dans l'autre, on peut voir que les empreintes 2 et 2' de ces matrices forment alors une empreinte complète, ici sensiblement tubulaire uniforme cylindrique. Dans une version non représentée, l'empreinte complète pourrait être sensiblement tubulaire polygonale.In FIG. 5 which represents, as already stated, two matrices 1, 1 'imbricated one in the other, it can be seen that the imprints 2 and 2' of these matrices then form a complete imprint, here substantially cylindrical uniform cylindrical . In a version not shown, the complete impression could be substantially tubular polygonal.

Sur la figure 6, on peut voir en coupe ce que donne l'imbrication des matrices.In Figure 6, we can see in section what gives the nesting matrices.

Les dents 3, respectivement 3' de l'une des matrices 1, respectivement 1' s'intercalent dans les interstices correspondant de l'autre matrice de telle sorte qu'en coupe, il y a pratiquement une continuité de matière.The teeth 3 and 3 'respectively of one of the dies 1 and 1' are interposed in the corresponding interstices of the other matrix so that in section there is practically a continuity of material.

L'invention propose une structure particulière afin d'utiliser deux matrices strictement identiques en permettant en outre de les présenter face à face, quelles que soient leurs positions parmi les deux positions relatives possibles qui sont retournées de 180° l'une par rapport à l'autre.The invention proposes a particular structure in order to use two strictly identical matrices while also making it possible to present them face to face, whatever their positions among the two possible relative positions which are turned by 180 ° relative to each other. 'other.

Autrement dit, dans la position imbriquée des figures 5 et 6, on obtient le même résultat en retournant l'une des matrices 1 ou 1' de 180° autour d'un axe, par rapport à la figure 5, qui serait perpendiculaire à la ligne de coupe référencée VI-VI, ce que ne permet pas l'art antérieur précité.In other words, in the nested position of FIGS. 5 and 6, the same result is obtained by returning one of the matrices 1 or 1 'by 180 ° about an axis, with respect to FIG. 5, which would be perpendicular to the cutting line referenced VI-VI, which does not allow the aforementioned prior art.

A cet effet et comme le montre bien la figure 4, pour chaque matrice les dents 3 et respectivement les interstices 4 disposés d'un côté du plan longitudinal médian de l'empreinte 2, passant ici par l'axe longitudinal L représenté sur la figure, s'alignent sur les interstices 4 et respectivement les dents 3 disposés de l'autre côté dudit plan longitudinal.For this purpose and as is well shown in FIG. 4, for each matrix the teeth 3 and the interstices 4, respectively, are arranged on one side of the median longitudinal plane of the cavity 2, passing here through the longitudinal axis L shown in FIG. , align with the interstices 4 and respectively the teeth 3 disposed on the other side of said longitudinal plane.

On peut aussi voir sur la figure 4 que chaque extrémité transversale de la matrice commence de manière identique, d'un côté du plan longitudinal médian de l'empreinte, par au moins une partie de dent 3 et/ou au moins une partie d'interstice 4, et, de l'autre côté dudit plan, réciproquement et inversement, par au moins une partie d'interstice 4 et/ou au moins une partie de dent 3.It can also be seen in FIG. 4 that each transverse end of the die starts identically, on one side of the median longitudinal plane of the impression, by at least a portion of tooth 3 and / or at least a portion of gap 4, and, on the other side of said plane, reciprocally and vice versa, by at least a gap portion 4 and / or at least a tooth portion 3.

Dans l'exemple représenté, les extrémités sont d'ailleurs munies d'une partie seulement de dent 3 ou d'interstice 4.In the example shown, the ends are also provided with only a portion of tooth 3 or gap 4.

En outre, ladite figure 4 de l'exemple représenté à quatre dents, montre que d'un côté à l'autre de la matrice et par rapport à l'axe transversal T, les dents 3 les plus voisines de cet axe sont disposées de part et d'autre de celui-ci.In addition, said FIG. 4 of the example shown with four teeth shows that, from one side to the other of the matrix and with respect to the transverse axis T, the teeth 3 closest to this axis are disposed of on both sides of it.

De la sorte, on peut alors constater que les dents 3 et les interstices 4 disposés d'un côté dudit plan longitudinal par rapport aux dents et interstices disposés de l'autre côté, se correspondent après une rotation d'un angle plat autour de l'axe défini par l'intersection dudit plan longitudinal et d'un plan transversal médian de l'empreinte, passant ici par l'axe T représenté sur ladite figure 4, l'axe de rotation passant donc par le point O d'intersection des axes précités L et T.In this way, it can then be seen that the teeth 3 and the gaps 4 arranged on one side of said longitudinal plane with respect to the teeth and interstices arranged on the other side, correspond after a rotation of a flat angle around the an axis defined by the intersection of said longitudinal plane and a median transverse plane of the cavity, passing here by the axis T shown in said FIG. 4, the axis of rotation therefore passing through the intersection point O aforementioned axes L and T.

Si dans le mode de réalisation des figures 1 à 6, l'empreinte 2, 2' de chaque matrice 1, 1' forme une partie de cylindre uniforme, outre le fait qu'il pourrait s'agir, comme déjà dit, d'une partie de polygone, l'empreinte peut également varier dans le sens longitudinal, comme dans le mode de réalisation représenté sur les figures 7 à 9.If in the embodiment of FIGS. 1 to 6, the impression 2, 2 'of each matrix 1, 1' forms a uniform cylinder part, in addition to the fact that it could be, as already said, of a portion of polygon, the imprint may also vary in the longitudinal direction, as in the embodiment shown in Figures 7 to 9.

Comme déjà dit, les figures 7 à 9 correspondent aux figures respectivement 2, 4 et 6 du mode de réalisation précédemment décrit.As already mentioned, FIGS. 7 to 9 correspond to FIGS. 2, 4 and 6 respectively of the embodiment previously described.

Pour faciliter la compréhension, on a repris les mêmes références en rajoutant un prime à chaque numéro, de manière telle que la matrice 1" comporte des dents 3" et des interstices 4" de manière à s'imbriquer avec une autre matrice munie de dents 3'".For ease of understanding, the same references have been used by adding a bonus to each number, in such a way that the matrix 1 "has teeth 3" and gaps 4 "so as to interlock with another matrix provided with teeth. 3 ".

Toutefois dans ce mode de réalisation, l'empreinte 2" est ici formée de plusieurs parties de cylindres concentriques alternées dans le sens longitudinal, les dents et les interstices étant décalés dans le sens transversal afin d'assurer la continuité des empreintes.However, in this embodiment, the impression 2 "here is formed of several parts of concentric cylinders alternated in the longitudinal direction, the teeth and the interstices being offset in the transverse direction to ensure the continuity of the impressions.

Dans l'exemple représenté, l'empreinte en creux 2" comprend trois parties de cylindres concentriques 5" de même diamètre qui sont alternées et séparées par deux parties de cylindres 6' d'un diamètre plus petit.In the example shown, the indentation 2 "comprises three parts of concentric cylinders 5" of the same diameter which are alternated and separated by two parts of cylinders 6 'of smaller diameter.

Toutefois, les parties de cylindres 6' pourraient être des parties polygonales ou autres faisant saillie vers l'intérieur et de façon générale, au moins deux parties de cylindres concentriques peuvent être séparées par au moins une saillie radiale orientée vers l'intérieur de l'empreinte.However, the cylinder parts 6 'could be inwardly projecting polygonal or other parts and in general, at least two concentric cylinder portions can be separated by at least one inwardly directed radial projection of the footprint.

Un jeu de deux matrices de ce type permet de réaliser des gorges sur la pièce sertie.A set of two dies of this type allows for grooves on the crimped part.

Il est très clair que l'invention concerne aussi bien un jeu de deux matrices nécessaires pour un sertissage, qu'une seule matrice et ce, d'autant plus qu'un jeu comporte deux matrices strictement identiques.It is very clear that the invention concerns both a set of two matrices necessary for a crimping, a single matrix and this, especially since a game has two strictly identical matrices.
