Description

La présente invention se rapporte à la réalisation d'outils d'assemblage sans élément rapporté de tôle par emboutissage sertissage de points de toutes formes, dont les matrices sont posées glissantes sur la face d'emboutissage de l'emboutissoir.The present invention relates to the production of assembly tools without insert sheet metal stamping crimping points of all shapes, whose dies are laid sliding on the stamping face of the stamping machine.

La présente invention se rapporte à la réalisation des points de toutes formes d'assemblage de tôles. La forme de la cavité dans la tôle côté poinçon est donnée par ledit poinçon. La forme de la saillie côté des matrices est donnée par la forme desdites matrices, lesdites matrices étant montées glissantes sur la face d'emboutissage de l'emboutissoir. Les matrices posées sur l'emboutissoir induisent par leurs épaisseurs la hauteur de la saillie du point de sertissage. L'invention concerne l'assemblage de tôles dans lequel on superpose, au moins deux tôles. A l'aide d'un poinçon de matrices et d'un emboutissoir on réalise simultanément dans lesdites tôles, à partir d'une face, une cavité 15 sur l'une des tôles s'insérant dans la saillie de l'autre tôle, ladite cavité formant un élargissement au voisinage de son fond, tandis que la saillie par fluage, forme un évasement s'insérant dans l'élargissement. Les outils à matrices mobiles, à ce jour, ont matrices, coquilles, lames, plaquettes, appuyées ou guidées autour ou latéralement de la partie réalisant 20 l'emboutissage. L'invention concerne la conception des outils pour la réalisation de ces points d'assemblage. Pour réaliser ce type de point on utilisera d'une part un poinçon et un serre-flanc, et d'autre part un ensemble matrices et emboutissoir. Ledit 25 emboutissoir dont la face supérieur reçoit les matrices et embouti le point dans la surface laissée par lesdites matrices a une rainure de forme sur ladite surface pour maîtriser le fluage de la matière. Le poinçon et l'emboutissoir seront fixés aux portes, poinçon ou emboutissoir, avec une forme prismatique de manière à ce qu'ils soient orientés autour de leurs axes. Ce type de 30 montage permet d'obtenir des outils compacts et robustes. Le nombre de matrices est déterminé par la forme de la saillie. Dans le cas de la réalisation d'un point de forme cylindrique l'orientation des outils n'est pas indispensable. L'invention va maintenant être décrite plus en détails en se référant à 35 un mode de réalisation particulier, donné à titre d'exemple seulement, représentée aux dessins annexés, dans lesquels : La figure 1 montre une vue en coupe des outils La figure 2 montre une vue de deux outils (02) emboutissoir et matrices, l'un avec deux matrices pour réaliser un point de forme rectangulaire, l'autre avec quatre matrices pour réaliser un point de forme circulaire. La figure 3 montre une vue de l'ensemble poinçon (01), de l'ensemble 5 matrices emboutisseur (02), matrices fermées, et de l'ensemble (02), matrices ouvertes de l'outillage pour réaliser un point de forme circulaire. La figure 4 montre une vue de l'ensemble poinçon (01), de l'ensemble matrices emboutisseur (02), matrices fermées, et de l'ensemble (02), matrices ouvertes de l'outillage pour réaliser un point de forme rectangulaire. En référence à ces dessins, à la figure 1 on représente une coupe de l'ensemble de l'outil, comprenant l'outil supérieur (01) et l'outil inférieur (02). L'outil supérieur (01) comprend un poinçon (1) emboîté dans son porte outil (11), un appui serre flanc (8), un serre-flanc (9) chassé sur le poinçon retenu par des griffes. 15 L'outil inférieur (02) comprend un emboutissoir (2) emboîté dans son porte-outil (12), un ensemble de matrices (3)-(4) ou (3)-(4)-(5)-(6) posé sur l'emboutissoir. Les matrices sont tenues par les languettes (15) et maintenues en position par un moyen élastique : les ressorts (16). La surface (14) a deux fonctions, emboutir les tôles et guider les matrices, ce qui permet de fabriquer 20 un outil très compact. La hauteur de la saillie est donnée par l'épaisseur des matrices. Des empreintes (17) sont pratiquées sur l'emboutissoir (2) pour maitriser la déformation du point lors de l'emboutissage. Lors d'un assemblage de tôle, l'ensemble (01) descend sur l'ensemble (02), le serre-flanc (09) plaque les tôles à assembler, puis se comprime. Le 25 poinçon (1) pénètre la tôle (25) avec ou sans découpage selon la forme et le jeu donné avec les matrices, dans le même temps la tôle côté matrices forme une saillie avec ou sans découpage entre les matrices. La matière des tôles (25) prises entre le poinçon (1) et l'emboutissoir (2) flue sur les côtés et dans les empreintes (17). Les matrices (3)-(4) ou (3)-(4)-(5)-(6) glissent sur 30 l'emboutissoir et s'écartent figure 3 et 4 outil (02). Le point d'assemblage et alors formé. L'actionneur remonte l'outil supérieur, le poinçon (1) se dégage de l'empreinte extrait par le serre flanc (9), le point est dégagé des matrices (3)-(4) ou (3)-(4)-(5)-(6) sans effort dû à leur montage glissant. Les matrices reviennent en position jointive, rappelées par les ressorts (16). 35 Les empreintes (17) permettent de contrôler le fluage. L'épaisseur des matrices donne la hauteur de la saillie.The present invention relates to the realization of points of all forms of sheet metal assembly. The shape of the cavity in the punch side plate is given by said punch. The shape of the protrusion on the side of the dies is given by the shape of said dies, said dies being slidably mounted on the stamping face of the embossing machine. The dies placed on the embosser induce by their thicknesses the height of the projection of the crimping point. The invention relates to the assembly of sheets in which is superimposed at least two sheets. With the aid of a die punch and a stamping die, a cavity 15 is produced simultaneously in said sheets from one face on one of the sheets which fit into the projection of the other sheet, said cavity forming an enlargement near its bottom, while the creep protrusion forms a widening fitting into the enlargement. The mobile die tools, to date, have dies, shells, blades, plates, pressed or guided around or laterally of the part making the stamping. The invention relates to the design of tools for the realization of these assembly points. To achieve this type of point will be used on the one hand a punch and a flank, and on the other hand a set of dies and emboutissoir. Said stamping machine whose upper face receives the dies and stamps the point in the surface left by said dies has a shape groove on said surface to control the creep of the material. The punch and the punch will be attached to the doors, punch or embosser, with a prismatic shape so that they are oriented around their axes. This type of assembly makes it possible to obtain compact and robust tools. The number of matrices is determined by the shape of the projection. In the case of the realization of a point of cylindrical shape the orientation of the tools is not essential. The invention will now be described in more detail with reference to a particular embodiment, given by way of example only, shown in the accompanying drawings, in which: Figure 1 shows a sectional view of the tools Figure 2 shows a view of two tools (02) stamping and dies, one with two dies to make a point of rectangular shape, the other with four dies to achieve a point of circular shape. FIG. 3 shows a view of the punch assembly (01), of the assembly 5 stamping dies (02), closed dies, and of the assembly (02), open dies of the tooling for producing a shape point circular. FIG. 4 shows a view of the punch assembly (01), of the stamping die assembly (02), closed dies, and of the assembly (02), of the open dies of the tooling for producing a rectangular-shaped dot. . Referring to these drawings, in Figure 1 is shown a section of the entire tool, comprising the upper tool (01) and the lower tool (02). The upper tool (01) comprises a punch (1) fitted into its tool holder (11), a flank support (8), a flange clamp (9) driven on the punch retained by claws. The lower tool (02) comprises a plunger (2) fitted into its tool holder (12), a set of dies (3) - (4) or (3) - (4) - (5) - (6). ) placed on the embosser. The dies are held by the tongues (15) and held in position by an elastic means: the springs (16). The surface (14) has two functions, stamping the sheets and guiding the dies, thereby making a very compact tool. The height of the projection is given by the thickness of the matrices. Fingerprints (17) are made on the embosser (2) to control the deformation of the point during stamping. During a sheet assembly, the assembly (01) descends on the assembly (02), the side clamp (09) plates the plates to be assembled, then compresses. The punch (1) penetrates the sheet (25) with or without cutting according to the shape and the game given with the dies, at the same time the plate side die forms a projection with or without cutting between the dies. The material of the sheets (25) taken between the punch (1) and the embosser (2) flue on the sides and in the indentations (17). The dies (3) - (4) or (3) - (4) - (5) - (6) slide on the embossing machine and move away from FIG. 3 and 4 tool (02). The assemblage point and then formed. The actuator raises the upper tool, the punch (1) is released from the impression extracted by the sidewall (9), the point is cleared from the dies (3) - (4) or (3) - (4) - (5) - (6) without effort due to their sliding mounting. The dies return in contiguous position, recalled by the springs (16). Fingerprints (17) control creep. The thickness of the dies gives the height of the projection.

Les matrices étant posées sur l'emboutissoir, elles subissent une contrainte de compression, pas de contrainte due au flambage ou à l'arcboutement. Ce montage est plus compact et robuste que ce qui est fait à ce jour. La forme du point est générée par le choix de l'outillage. Un poinçon de forme circulaire et un ensemble de matrices circulaires figure 3 permettra de façonner des points de forme circulaire étanche. Solution applicable dans la plupart des assemblages. Un poinçon de forme rectangulaire figure 4, avec deux arrêtes 10 tranchantes et deux cotés rayonnés et deux matrices avec une empreinte rectangulaire dont deux côtés sont coupants et deux côtés sont rayonnés permettra de façonner des points avec deux côtés découpés et deux côtés pliés. Cette solution peut s'appliquer pour tout assemblage, mais n'est pas toujours étanche, elle est efficace pour assembler les tôles dures comme les 15 inox ou pour marier des tôles de duretés différentes comme les aluminiums avec les aciers. La technique est utilisée dans l'industrie utilisant des tôles, électroménager, automobile, ventilation, électromécanique...The matrices being placed on the embosser, they undergo a compressive stress, no stress due to buckling or arcboutement. This assembly is more compact and robust than what is done today. The shape of the point is generated by the choice of tooling. A circular shaped punch and a set of circular dies Figure 3 will shape points of sealed circular shape. Solution applicable in most assemblies. A rectangular shaped punch 4, with two sharp edges 10 and two radiated sides and two dies with a rectangular imprint whose two sides are sharp and two sides are radiated will shape points with two cut sides and two folded sides. This solution can be applied for any assembly, but is not always waterproof, it is effective for assembling hard plates such as stainless steel or for marrying sheets of different hardness such as aluminum with steel. The technique is used in the industry using sheet metal, household appliances, automotive, ventilation, electromechanical ...
