État de la technique State of the art
Comme illustré aux figures 1 à 3, un insert selon l'art antérieur se présente 20 sous la forme d'un corps allongé 1 prolongé à une extrémité par une tête 2 en forme de collerette. La tête 2 comporte une surface d'appui 3 orientée vers le corps allongé 1. Un épaulement 4 fait saillie de la surface d'appui 3 de la tête au niveau de la jonction entre la tête et le corps allongé 1. Cet épaulement 4 présente des protubérances 5 s'étendant axialement à sa 25 surface. Un tel insert est destiné à être assemblé par sertissage sur un support 6 comportant une ouverture 7 dont le diamètre est sensiblement égal au diamètre de l'épaulement 4. Le procédé de sertissage, d'un tel insert sur un support métallique 6 comporte les étapes suivantes : on introduit l'insert dans l'ouverture 7 jusqu'à obtenir la mise en contact 30 des protubérances 5 de l'épaulement avec le support,5 As illustrated in FIGS. 1 to 3, an insert according to the prior art is in the form of an elongate body 1 extended at one end by a collar-shaped head 2. The head 2 has a bearing surface 3 oriented towards the elongate body 1. A shoulder 4 projects from the bearing surface 3 of the head at the junction between the head and the elongate body 1. This shoulder 4 has protuberances 5 extending axially at its surface. Such an insert is intended to be assembled by crimping on a support 6 having an opening 7 whose diameter is substantially equal to the diameter of the shoulder 4. The method of crimping, such an insert on a metal support 6 comprises the steps following: the insert is introduced into the opening 7 until the protuberances 5 of the shoulder are brought into contact with the support,
on rapporte une enclume 8 sur une surface de la tête 2 opposée à sa surface d'appui 3, on rapporte une bouterolle 9 sur le corps allongé 1 de l'insert pour mettre en contact une extrémité libre de la bouterolle avec une première face 6a du support métallique 6. La bouterolle est un outil permettant d'effectuer une déformation d'un métal, et comporte un alésage dont le gabarit correspond sensiblement au corps allongé 1, on rapproche enclume et la bouterolle, jusqu'à obtenir la mise en contact de la surface d'appui 3 de la tête 2 de l'insert avec une seconde face 6b du support métallique 6. Les protubérances 5 sont ainsi enfoncées en force dans le support 6. an anvil 8 is reported on a surface of the head 2 opposite its bearing surface 3, there is reported a rivet 9 on the elongate body 1 of the insert for bringing a free end of the rivet into contact with a first face 6a 6. The rivet is a tool for deforming a metal, and has a bore whose template corresponds substantially to the elongate body 1, is brought anvil and the rivet, to get in contact of the bearing surface 3 of the head 2 of the insert with a second face 6b of the metal support 6. The protuberances 5 are thus forced into the support 6.
Pour réaliser un tel sertissage, l'insert est réalisé dans un matériau ou un alliage indéformable tel que l'acier. Le support est généralement réalisé dans un matériau ou un alliage suffisamment malléable de manière à subir une déformation. Cette déformation permet la pénétration des protubérances 5 de l'insert dans le support lors du mouvement de rapprochement de l'enclume 8 et de la bouterolle 9. Le sertissage obtenu par le procédé décrit ci-dessus permet de rendre l'insert solidaire du support à la fois en rotation et en translation. Il subsiste néanmoins un risque d'étanchéité imparfaite entre les deux faces 6a et 6b du support métallique 6. To achieve such crimping, the insert is made of a material or an indeformable alloy such as steel. The support is generally made of a material or alloy sufficiently malleable to undergo deformation. This deformation allows penetration of the protuberances 5 of the insert into the support during the movement of approximation of the anvil 8 and the rivet 9. The crimping obtained by the method described above makes it possible to make the insert integral with the support both in rotation and in translation. There remains however a risk of imperfect sealing between the two faces 6a and 6b of the metal support 6.
Objet de l'invention L'objet de l'invention consiste à réaliser un sertissage étanche d'un support avec un insert. OBJECT OF THE INVENTION The object of the invention is to perform a tight crimping of a support with an insert.
Ce but est atteint par le fait que l'ouverture ayant une forme polygonale et 30 l'épaulement étant de hauteur supérieure à l'épaisseur du support métallique au niveau de l'ouverture, le procédé comporte les étapes suivantes:25 This object is achieved by having the aperture having a polygonal shape and the shoulder being greater than the thickness of the metal support at the aperture, the method comprises the following steps:
on introduit l'insert dans l'ouverture du support métallique jusqu'à obtenir un contact entre le support et la surface d'appui, l'épaulement étant sur une portion en saillie du support, on rapporte sur le corps allongé une bouterolle jusqu'à obtenir un contact entre l'épaulement et une extrémité libre de la bouterolle, ladite bouterolle comportant un alésage correspondant au gabarit du corps allongé, on rapporte, sur une surface de la tête opposée à sa surface d'appui, une excroissance en saillie d'une enclume, on rapproche l'enclume et la bouterolle déformant simultanément la tête et l'épaulement de l'insert pour combler des vides entre l'épaulement et l'ouverture, et pour constituer un bourrelet de sertissage entre l'extrémité libre de la bouterolle et le support métallique. inserting the insert in the opening of the metal support until a contact between the support and the bearing surface, the shoulder being on a projecting portion of the support, is reported on the elongated body a snap until to obtain a contact between the shoulder and a free end of the rivet, said rivet having a bore corresponding to the template of the elongated body, is reported, on a surface of the head opposite to its bearing surface, a protruding protrusion d an anvil, the anvil and the rivet are deformed simultaneously deforming the head and the shoulder of the insert to fill voids between the shoulder and the opening, and to form a crimping bead between the free end of the snap and the metal support.
Un tel procédé permet de garantir une étanchéité parfaite du sertissage ainsi qu'une solidarisation de l'insert avec le support en translation et en rotation. Such a method makes it possible to guarantee a perfect sealing of the crimping as well as a fastening of the insert with the support in translation and in rotation.
Selon des variantes, les inserts utilisés peuvent se présenter sous forme d'écrous, de goujons ou encore d'entretoise. Description sommaire des dessins According to variants, the inserts used may be in the form of nuts, studs or spacer. Brief description of the drawings

Description d'un mode préférentiel de l'invention 10 Selon un mode de réalisation de l'invention, illustré aux figures 4 à 6, on cherche à solidariser un insert sur un support métallique 6 par déformation à froid. L'insert comporte un corps allongé 1 prolongé à une de ses extrémités par une tête 2 formant une collerette. La tête 2 de l'insert comporte une 15 surface d'appui 3 orientée vers le corps allongé 1. L'insert comporte en outre un épaulement 4 faisant saillie de la surface d'appui 3 de la tête 2 au niveau de la jonction entre le corps allongé 1 et la tête 2, l'épaulement 4 réalisant le tour du corps allongé. Figure 1 illustrates an insert according to the prior art. Figures 2 to 3 illustrate, in section, a method of crimping the prior art of an insert according to Figure 1 with a metal support. FIG. 4 illustrates an insert according to the invention. FIGS. 5 and 6 illustrate, in sectional view, various steps of the crimping method according to the invention. Figures 7 and 8 illustrate, in section, different variants of inserts. Figures 9 and 10 illustrate, in section, a variant of the crimping process. DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION According to one embodiment of the invention, illustrated in FIGS. 4 to 6, it is sought to join an insert to a metal support 6 by cold deformation. The insert comprises an elongated body 1 extended at one of its ends by a head 2 forming a collar. The head 2 of the insert has a bearing surface 3 oriented towards the elongated body 1. The insert further comprises a shoulder 4 projecting from the bearing surface 3 of the head 2 at the junction between the elongate body 1 and the head 2, the shoulder 4 providing the elongate body turn.
20 Un tel insert est serti sur un support métallique 6 comportant une ouverture 7 de forme polygonale. Le diamètre de l'ouverture 7 permet l'introduction de l'épaulement 4 de l'insert présentant une hauteur supérieure à l'épaisseur du support métallique 6 au niveau de l'ouverture 7. Such an insert is crimped onto a metal support 6 having an opening 7 of polygonal shape. The diameter of the opening 7 allows the introduction of the shoulder 4 of the insert having a height greater than the thickness of the metal support 6 at the opening 7.
25 Afin de réaliser un sertissage étanche de l'insert sur le support 6, le procédé de sertissage comporte les étapes suivantes : on introduit le corps allongé 1 dans l'ouverture 7 jusqu'à obtenir un contact entre la surface d'appui 3 de la tête 2 et le support métallique 6, l'épaulement 4 de l'insert étant sur une portion en saillie du support 30 métallique 6, In order to effect a tight crimping of the insert on the support 6, the crimping method comprises the following steps: the elongated body 1 is introduced into the opening 7 until contact is obtained between the bearing surface 3 of the the head 2 and the metal support 6, the shoulder 4 of the insert being on a projecting portion of the metal support 6,
on rapporte une bouterolle 9 sur le corps allongé 1 jusqu'à obtenir un contact entre l'épaulement 4 et une extrémité libre de la bouterolle 9, la bouterolle 9 comportant un alésage correspondant au gabarit du corps allongé 1, on rapporte une excroissance 10 en saillie d'une enclume 8 sur une surface de la tête 2 de l'insert opposée à sa surface d'appui 3, l'excroissance 10 étant alors mise en contact avec la tête 2 de l'insert, on rapproche ensuite l'enclume et la bouterolle, ce rapprochement a pour effet de déformer simultanément la tête 2 et l'épaulement 4 de l'insert pour combler les vides entre l'épaulement 4 de l'insert et l'ouverture 7 polygonale du support. La matière est donc déplacée en direction de l'épaulement 4 par la pression exercée par l'excroissance 10 de l'enclume 8 provoquant une déformation de la tête 2 correspondant au volume de l'excroissance 10 de l'enclume. La contre-pression exercée par la bouterolle 9 permet de chasser la matière dans des vides situés entre l'épaulement 4 et l'ouverture 7 et de déformer l'épaulement 4 jusqu'à l'obtention d'un bourrelet de sertissage 11 entre l'extrémité libre de la bouterolle 9 et le support métallique 6. Seul l'insert est déformé lors de son sertissage sur le support 6. a rivet 9 is attached to the elongated body 1 until contact is made between the shoulder 4 and a free end of the rivet 9, the rivet 9 having a bore corresponding to the template of the elongate body 1, a protrusion 10 is reported in protrusion of an anvil 8 on a surface of the head 2 of the insert opposite to its bearing surface 3, the protrusion 10 then being brought into contact with the head 2 of the insert, then approximates the anvil and the rivet, this approximation has the effect of simultaneously deforming the head 2 and the shoulder 4 of the insert to fill the voids between the shoulder 4 of the insert and the polygonal opening 7 of the support. The material is thus displaced towards the shoulder 4 by the pressure exerted by the protrusion 10 of the anvil 8 causing a deformation of the head 2 corresponding to the volume of the protrusion 10 of the anvil. The counterpressure exerted by the rivet 9 makes it possible to drive the material into voids situated between the shoulder 4 and the opening 7 and to deform the shoulder 4 until a crimping bead 11 is obtained between the free end of the rivet 9 and the metal support 6. Only the insert is deformed during its crimping on the support 6.
Après retrait de la bouterolle 9 et de l'enclume 8, les vides situés entre l'épaulement 4 et l'ouverture 7 du support 6 sont complètement comblés. After removal of the rivet 9 and the anvil 8, the gaps between the shoulder 4 and the opening 7 of the support 6 are completely filled.
Un tel sertissage à froid permet d'assurer une solidarisation en translation de l'insert sur le support grâce au bourrelet 11. Such cold crimping makes it possible to secure the insert in translation on the support thanks to the bead 11.
L'insert est immobilisé en rotation, la nature polygonale de l'ouverture 7 empêchant toute rotation de l'insert une fois les vides comblés. Le contact réalisé sur le support 6 par le bourrelet de sertissage 11 d'une part et par la surface d'appui 3 de la tête 2 de l'insert d'autre part permet d'assurer l'étanchéité du sertissage du support métallique 6 avec l'insert. The insert is immobilized in rotation, the polygonal nature of the opening 7 preventing rotation of the insert once the voids are filled. The contact made on the support 6 by the crimping bead 11 on the one hand and by the bearing surface 3 of the head 2 of the insert on the other hand makes it possible to seal the crimping of the metal support 6 with the insert.
Dans une variante illustrée à la figure 7, l'insert comporte un alésage s'étendant coaxialement dans le corps allongé 1 à une extrémité opposé de la tête 2 en forme de collerette. Cet alésage comporte une portion 12 taraudée, formant un écrou borgne. Un tel écrou peut être serti à un support métallique selon le procédé de sertissage décrit ci-dessus. Dans une variante (non représentée) l'insert a une forme de goujon servant de moyens de fixation. In a variant illustrated in Figure 7, the insert has a bore extending coaxially in the elongated body 1 at an opposite end of the head 2 in the form of flange. This bore has a threaded portion 12, forming a blind nut. Such a nut can be crimped to a metal support according to the crimping method described above. In a variant (not shown) the insert has a form of stud serving as fixing means.
io De préférence, l'excroissance 10 de l'enclume 8 est une couronne circulaire dont le diamètre extérieur correspond sensiblement au diamètre de l'épaulement 4 de l'insert. L'insert est placé coaxialement à cette couronne lorsque l'enclume est rapportée sur la tête 2. Preferably, the protrusion 10 of the anvil 8 is a circular ring whose outer diameter substantially corresponds to the diameter of the shoulder 4 of the insert. The insert is placed coaxially with this ring when the anvil is attached to the head 2.
15 Dans une autre variante illustrée aux figures 8 à 10, le corps allongé 1 de l'insert comporte un alésage débouchant s'étendant coaxialement dans le corps allongé 1, l'insert formant ainsi une entretoise. L'excroissance 10 de l'enclume, correspondant à un tel insert, comporte un tenon 13 dont le diamètre est équivalent au diamètre de l'alésage de l'insert. Ce tenon 13 est 20 introduit dans l'alésage du corps allongé 1 lors de la mise en contact de l'excroissance 10 de l'enclume 8 et de la tête 2. L'excroissance comporte en outre un renfort 14 entourant le tenon 13 à la jonction de ce dernier et de l'enclume 8. In another variant illustrated in FIGS. 8 to 10, the elongate body 1 of the insert has a through bore extending coaxially in the elongated body 1, the insert thus forming a spacer. The protrusion 10 of the anvil, corresponding to such an insert, comprises a pin 13 whose diameter is equivalent to the diameter of the bore of the insert. This pin 13 is introduced into the bore of the elongate body 1 when the protuberance 10 of the anvil 8 and the head 2 are brought into contact. The protrusion further comprises a reinforcement 14 surrounding the pin 13 to the junction of the latter and the anvil 8.
25 Lors du sertissage de l'insert sur le support métallique 6, on rapporte l'excroissance 10 de l'enclume sur la tête 2. Le tenon 13 est inséré dans l'alésage de l'insert et une partie supérieure du renfort 14 est mise en contact avec la tête 2. L'enclume et la bouterolle sont rapprochées l'une de l'autre, la pression exercée par le renfort 14 de l'enclume déplace la matière en 30 direction de l'épaulement 4. La contre-pression exercée par la bouterolle 9 permet de chasser la matière dans les vides formés entre l'épaulement 4 de When crimping the insert on the metal support 6, the protrusion 10 of the anvil is reported on the head 2. The post 13 is inserted into the bore of the insert and an upper portion of the reinforcement 14 is The anvil and the rivet are brought closer to each other, the pressure exerted by the reinforcement 14 of the anvil moves the material towards the shoulder 4. The pressure exerted by the rivet 9 allows to drive the material in the voids formed between the shoulder 4 of
l'insert et l'ouverture 7 du support. L'épaulement 4 est ainsi déformé jusqu'à l'obtention d'un bourrelet de sertissage 11 entre l'extrémité libre de la bouterolle 9 et le support métallique 6. the insert and the opening 7 of the support. The shoulder 4 is thus deformed until a crimping bead 11 is obtained between the free end of the rivet 9 and the metal support 6.
De préférence, l'insert est métallique. À titre d'exemple, l'insert peut être réalisé en aluminium, en acier ou en un alliage acier/inox. L'insert doit être déformable de manière à former le bourrelet de sertissage 11 et combler les vides entre l'épaulement 4 et l'ouverture 7 du support 6 lors de l'introduction de l'insert. Preferably, the insert is metallic. For example, the insert can be made of aluminum, steel or a steel / stainless steel alloy. The insert must be deformable so as to form the crimping bead 11 and fill the voids between the shoulder 4 and the opening 7 of the support 6 during the introduction of the insert.
L'enclume peut comporter un alésage correspondant au gabarit de la tête 2 de l'insert, l'excroissance 10 étant formée sur le fond de cet alésage. Un tel alésage forme une matrice permettant d'éviter que la matière soit chassée parallèlement à l'enclume lors du rapprochement de l'enclume 8 et de la bouterolle 9 pendant le sertissage, la matière étant chassée uniquement perpendiculairement à l'enclume 8 en direction de l'épaulement 4. The anvil may comprise a bore corresponding to the jig of the head 2 of the insert, the protrusion 10 being formed on the bottom of this bore. Such a bore forms a matrix making it possible to prevent the material being driven parallel to the anvil when the anvil 8 and the rivet 9 are brought together during crimping, the material being driven only perpendicularly to the anvil 8 in the direction shoulder 4.
Les différents procédés de sertissage tels que décris ci-dessus peuvent être utilisés pour assembler par sertissage trois écrous et une entretoise servant de douille de vidange sur une cuve de filtre à gazole. The various crimping methods as described above can be used to crimp together three nuts and a spacer serving as a drain socket on a diesel fuel filter tank.
