Description

L'invention concerne un dispositif d'assemblage de deux panneaux de tôle par sertissage selon le préambule de la revendication 1 (voir par exemple JP-A-2002 035865 ), ainsi qu'un procédé de sertissage utilisant un tel dispositif, en effectuant une opération de présertissage et une opération de sertissage.The invention relates to a device for assembling two crimping sheet metal panels according to the preamble of claim 1 (see for example JP-A-2002 035865 ), as well as a crimping method using such a device, performing a prestressing operation and a crimping operation.

Le sertissage est mis en oeuvre pour assembler les deux panneaux de tôles en repliant un bord du premier panneau sur un bord du second panneau.The crimping is used to assemble the two panels of sheets by folding an edge of the first panel on an edge of the second panel.

Les opérations de sertissage sont réalisées avec un bras mobile d'un robot portant un outil de sertissage incluant un galet ou une molette : le bras est alors déplacé le long du bord à sertir pour exercer sur celui-ci un effort par l'intermédiaire du galet.The crimping operations are carried out with a mobile arm of a robot carrying a crimping tool including a roller or a wheel: the arm is then moved along the edge to be crimped to exert on it a force through the roller.

Afin d'obtenir une qualité de pliage satisfaisante, il peut être indispensable de réaliser le sertissage en deux opérations, voire trois opérations.In order to obtain a satisfactory folding quality, it may be necessary to perform crimping in two operations, or even three operations.

Ainsi, le bras est déplacé une première fois le long du bord pour exercer un effort permettant de plier partiellement ce bord, puis il est déplacé une seconde fois le long du bord pour exercer un effort permettant de l'appliquer sur l'autre bord pour qu'il l'enserre.Thus, the arm is moved a first time along the edge to exert a force to partially fold this edge, then it is moved a second time along the edge to exert a force to apply it on the other edge to that he encloses it.

En effet, dans le cas d'un bord devant être replié sur un angle total valant important tel que 105 degrés, il n'est pas possible d'effectuer le repli complet du bord en une opération unique : celui-ci impliquerait qu'un unique galet forme un angle de 105 degrés avec le bord à sertir le long duquel il est déplacé.Indeed, in the case of an edge to be folded over a significant total angle such as 105 degrees, it is not possible to perform the complete folding of the edge in a single operation: it would imply that a Single roller forms an angle of 105 degrees with the crimp edge along which it is moved.

Une telle déformation du bord ne peut pas être réalisée en une opération unique : ceci provoquerait un déplacement latéral de la ligne de pliage par rapport à la ligne de pliage souhaitée.Such deformation of the edge can not be achieved in a single operation: this would cause a lateral displacement of the fold line with respect to the desired fold line.

Dans les dispositifs connus, l'effort exercé par le galet sur le bord à sertir est par exemple généré et/ou asservi grâce à un dispositif tel que celui décrit dans la demande de brevet FR-A-2 843 549 , en étant éventuellement contrôlé par un capteur.In known devices, the force exerted by the roller on the edge to be crimped is for example generated and / or enslaved by a device such as that described in FIG. the patent application FR-A-2,843,549 , possibly being controlled by a sensor.

Le but de l'invention est de proposer un moyen de réaliser le sertissage d'une pièce de façon simple et rapide et offrant une qualité satisfaisante.The object of the invention is to provide a means for performing the crimping of a part in a simple and fast manner and offering a satisfactory quality.

A cet effet, l'invention a pour objet un dispositif d'assemblage par pliage d'un bord d'un premier panneau de tôle sur un bord d'un second panneau de tôle tel que défini dans la revendication 1.To this end, the invention relates to a device for assembling by folding an edge of a first sheet metal panel on an edge of a second sheet metal panel as defined in claim 1.

De préférence l'outil comprend au moins un ressort se comprimant lorsque le balancier est écarté d'une position angulaire neutre.Preferably the tool comprises at least one spring compressing when the rocker is spaced from a neutral angular position.

De préférence l'outil comprend deux ressorts se comprimant respectivement lorsque le balancier est écarté de sa position neutre selon un premier ou un second sens de rotation autour de l'axe.Preferably the tool comprises two springs compressing respectively when the rocker is spaced from its neutral position in a first or a second direction of rotation about the axis.

De préférence l'angle que les axes des deux galet forment, vaut 55°.Preferably the angle that the axes of the two rollers form, is 55 °.

De préférence le balancier est monté pivotant par rapport à l'embase autour d'un axe coïncidant avec l'axe de pivotement du galet de sertissage.Preferably the balance is pivotally mounted relative to the base around an axis coinciding with the pivot axis of the crimping roller.

De préférence l'axe de pivotement du galet de sertissage et du balancier coupe un axe de symétrie du bras portant l'outil.Preferably, the pivot axis of the crimping roller and the rocker crosses an axis of symmetry of the arm carrying the tool.

L'invention concerne également un procédé d'assemblage par pliage d'un bord d'un premier panneau de tôle sur un bord d'un second panneau de tôle tel que défini dans la revendication 7, avec un dispositif selon l'invention comprenant un bras mobile portant un outil pour exercer un effort sur le bord du premier panneau afin d'une part de le plier vers le bord du second panneau et d'autre part de l'appliquer sur le bord du second panneau, comprenant au moins les étapes suivantes :

  • approche du bras mobile et positionnement de l'outil en contact avec une surface d'appui d'une matrice portant les panneaux à assembler,
  • application d'un effort sur l'outil,
  • déplacement de l'outil suivant une trajectoire programmée, avec maintien de l'effort exercé sur l'outil.
The invention also relates to a method of assembling by folding an edge of a first sheet metal panel on an edge of a second sheet metal panel as defined in claim 7, with a device according to the invention comprising a movable arm carrying a tool for exerting a force on the edge of the first panel in order to fold it towards the edge of the second panel and secondly to apply it on the edge of the second panel, comprising at least the steps following:
  • approaching the movable arm and positioning the tool in contact with a bearing surface of a matrix carrying the panels to be assembled,
  • application of an effort on the tool,
  • moving the tool along a programmed path, maintaining the force exerted on the tool.

Le dispositif selon l'invention, dont un premier mode de réalisation est représenté en figure 1 et 2, est destiné à assembler des pièces par sertissage ou pliage. Comme représenté sur la figure 3, cet assemblage consiste à replier un bord B1 d'un premier panneau P1 de tôle, sur un bord B2 d'un deuxième panneau P2 de tôle.The device according to the invention, a first embodiment of which is represented in figure 1 and 2 , is intended to assemble parts by crimping or folding. As shown on the figure 3 , this assembly consists in folding an edge B1 of a first panel P1 of sheet metal, on an edge B2 of a second panel P2 of sheet metal.

Les panneaux sont supportés par une matrice M, le pliage étant effectué avec un galet de présertissage 1 et un galet de sertissage 2 montés sur un outil porté par un bras mobile d'un robot.The panels are supported by a matrix M, the folding being carried out with a prestress roller 1 and a crimping roller 2 mounted on a tool carried by a mobile arm of a robot.

L'outil comprend à cet effet un support 3, ou balancier, portant les deux galets 1, 2, ce balancier étant monté sur une embase 7 en étant apte à pivoter autour d'un axe 4 par rapport à cette embase 7. L'axe 4 s'étend perpendiculairement à la direction de déplacement de l'outil 1, 2 le long du bord à sertir.The tool comprises for this purpose a support 3, or balance, carrying the two rollers 1, 2, this beam being mounted on a base 7 being able to pivot about an axis 4 relative to this base 7. The axis 4 extends perpendicularly to the direction of movement of the tool 1, 2 along the edge to be crimped.

L'embase 7 de l'outil est fixée à une extrémité non représentée du bras du robot par l'intermédiaire d'une tête de sertissage 8 comprenant une face 9 de fixation à cette extrémité de bras.The base 7 of the tool is attached to a not shown end of the robot arm via a crimping head 8 comprising a face 9 of attachment to this arm end.

Cette tête de sertissage 8 comprend par exemple des moyens permettant de piloter l'intensité de l'effort appliqué par les galets au bord à sertir, l'embase 7 étant rigidement fixée à un organe mobile de cette tête de sertissage.This crimping head 8 comprises, for example, means for controlling the intensity of the force applied by the rollers to the edge to be crimped, the base 7 being rigidly fixed to a movable member of this crimping head.

Cette tête 8 comprend par exemple un ressort qui est comprimé par le robot sur une course prédéterminée pour délivrer un effort de sertissage déterminé par la raideur du ressort et à la longueur de compression.This head 8 comprises for example a spring which is compressed by the robot on a predetermined stroke to deliver a crimping force determined by the stiffness of the spring and the length of compression.

Comme visible dans la figure 1, l'outil comprend également des ressorts 5 et 6 de mise en contrainte, respectivement du galet de pré sertissage et du galet de sertissage.As visible in the figure 1 , the tool also comprises springs 5 and 6 of stressing, respectively pre-crimping roller and crimping roller.

Plus particulièrement, le balancier 3 comprend deux branches, repérées respectivement par 3A et 3B parallèles l'une à l'autre et s'étendant de part et d'autre de l'embase 7, au-delà de l'axe de rotation 4.More particularly, the balance 3 comprises two branches, respectively marked by 3A and 3B parallel to one another and extending on either side of the base 7, beyond the axis of rotation 4 .

Le ressort 5 est interposé et maintenu en position entre la branche 3A et l'embase 7, le ressort 6 est interposé et maintenu en position entre la branche 3B et l'embase 7.The spring 5 is interposed and held in position between the leg 3A and the base 7, the spring 6 is interposed and held in position between the leg 3B and the base 7.

Une rotation du balancier 3 dans le sens direct sur la figure 1 tend à comprimer le ressort 5, et une rotation dans le sens indirect sur la figure 1 tend à comprimer le ressort 6.A rotation of the balance 3 in the direct direction on the figure 1 tends to compress the spring 5, and a rotation in the indirect direction on the figure 1 tends to compress the spring 6.

Ces ressorts tendent ainsi, conjointement, à ramener le balancier 3 dans une position angulaire dite neutre, correspondant à la position qu'occupe ce balancier sur les figures 1 et 2, et dans laquelle les branches 3A et 3B s'étendent parallèlement à l'embase 7.These springs thus tend, together, to bring the rocker 3 into a so-called neutral angular position, corresponding to the position occupied by this rocker on the Figures 1 and 2 , and in which the branches 3A and 3B extend parallel to the base 7.

En fonctionnement, si le galet de pré sertissage 1 rencontre une surépaisseur, il va tendre à faire pivoter le balancier 3 dans un sens tendant à comprimer le ressort 5, ce qui va augmenter sensiblement l'effort appliqué par ce galet au bord à sertir.In operation, if the pre-crimping roller 1 encounters an excess thickness, it will tend to rotate the rocker 3 in a direction tending to compress the spring 5, which will substantially increase the force applied by the roller edge to crimp.

De manière analogue, si le galet de sertissage 2 rencontre une surépaisseur, c'est le ressort 6 qui va être comprimé, tendant ainsi à augmenter sensiblement l'effort appliqué par ce galet 6.Similarly, if the crimping roller 2 encounters an excess thickness, the spring 6 will be compressed, thus tending to increase substantially the force applied by the roller 6.

Ainsi, l'effort de sertissage est appliqué par le bras et asservi via la tête de sertissage 8 pour correspondre à une valeur souhaitée de la somme des efforts appliqués par les deux galets 1 et 2 au bord à sertir. La répartition de cet effort entre le galet 1 et le galet 2 est gérée par les ressort 5 et 6 pour absorber au mieux les irrégularités rencontrées durant le déplacement de l'outil.Thus, the crimping force is applied by the arm and enslaved via the crimping head 8 to correspond to a desired value of the sum of the forces applied by the two rollers 1 and 2 to the edge to be crimped. The distribution of this force between the roller 1 and the roller 2 is managed by the spring 5 and 6 to absorb the best irregularities encountered during the movement of the tool.

Comme visible figure 2 les galets 1 et 2 sont portés respectivement par un axe A1 et par un axe A2 qui forment un angle non nul, noté W, l'un par rapport à l'autre.As visible figure 2 the rollers 1 and 2 are respectively carried by an axis A1 and by an axis A2 which form a non-zero angle, denoted W, with respect to each other.

Plus particulièrement, l'axe A1 et l'axe A2 sont inscrits dans deux plans parallèles, perpendiculaires à la trajectoire de l'outil. L'angle W correspond à l'angle séparant, dans le plan contenant l'axe A2, l'axe A2 et la projection orthogonale de l'axe A1 dans ce plan.More particularly, the axis A1 and the axis A2 are inscribed in two parallel planes, perpendicular to the path of the tool. The angle W corresponds to the angle separating, in the plane containing the axis A2, the axis A2 and the orthogonal projection of the axis A1 in this plane.

Lors d'un sertissage, le galet de pré sertissage 1 est positionné en appui sur une surface de guidage S de la matrice M dans laquelle ont été positionnés les panneaux de tôle P1 et P2 à sertir, en exerçant un effort sur le bord B1 via l'outil, pour plier ce bord B1 localement.During crimping, the pre-crimping roller 1 is positioned in abutment on a guide surface S of the matrix M in which the sheet metal panels P1 and P2 to be crimped have been positioned, exerting a force on the edge B1 via the tool, to fold this edge B1 locally.

Le bras mobile non représenté est ensuite déplacé pour déplacer l'outil le long du bord à sertir, en appui sur la surface de guidage S, de manière à exercer un effort sur le bord B1 à sertir.The not shown movable arm is then moved to move the tool along the edge crimping, resting on the guide surface S, so as to exert a force on the edge B1 to crimp.

Au fur et à mesure que l'outil avance le long du bord B1, celui-ci est d'abord plié par le galet de pré sertissage 1, puis appliqué sur le bord B2 du second panneau P2 par le galet de sertissage 2.As the tool advances along the edge B1, the latter is first folded by the pre-crimping roller 1, then applied on the edge B2 of the second panel P2 by the crimping roller 2.

Grâce à l'inclinaison relative W des deux galets 1, 2 le galet de présertissage 1 apporte les premières déformations du bord B1 du panneau P1 et le galet de sertissage 2, qui suit le galet 1 à faible distance, effectue le sertissage.Due to the relative inclination W of the two rollers 1, 2 the prestressing roller 1 provides the first deformations of the edge B1 of the panel P1 and the crimping roller 2, which follows the roller 1 at a short distance, performs the crimping.

L'angle W vaut avantageusement 55 degrés, ce qui permet, en pratique d'effectuer des sertissages dans lesquels le bord à sertir est plié d'un angle pouvant aller jusqu'à 105 degrés, en une seule passe, c'est-à-dire en un seul passage de l'outil de sertissage. Le temps de cycle d'un sertissage peut ainsi être divisé par deux.Advantageously, the angle W is 55 degrees, which makes it possible, in practice, to make crimps in which the crimping edge is bent at an angle of up to 105 degrees in a single pass, that is to say say in one pass the crimping tool. The cycle time of a crimp can thus be divided by two.

Le degré de liberté introduit par le balancier permet d'éviter notamment un marquage des pièces à sertir au passage d'un obstacle. Les ressorts 5 et 6 de mise en contrainte des galets permettent de réduire encore l'influence d'une surépaisseur sur la qualité du sertissage obtenu.The degree of freedom introduced by the balance makes it possible to avoid, in particular, marking of the parts to be crimped when passing an obstacle. The springs 5 and 6 stress the rollers can further reduce the influence of an extra thickness on the quality of crimping obtained.

Dans le premier mode de réalisation de l'invention, le support ou balancier 3 admet un axe de symétrique coïncidant avec l'axe de révolution AX de la tête de sertissage 8 lorsque ce balancier 3 occupe une position angulaire neutre, comme dans la figure 1.In the first embodiment of the invention, the support or pendulum 3 has an axis of symmetry coinciding with the axis of revolution AX of the crimping head 8 when the balance 3 occupies a neutral angular position, as in FIG. figure 1 .

Ainsi, les axes A1 et A2 des galets 1 et 2 sont situés respectivement en avant et en arrière d'un plan normal au déplacement de l'outil et contenant l'axe AX. La pression appliquée par la tête 8 est ainsi équitablement répartie sur le premier et le second galet 1 et 2, cette répartition étant de surcroît gérée par les ressorts de mise en contrainte 5 et 6 en cas d'inclinaison du balancier 3.Thus, the axes A1 and A2 of the rollers 1 and 2 are respectively forward and backward of a plane normal to the movement of the tool and containing the axis AX. The pressure applied by the head 8 is thus equitably distributed over the first and the second roller 1 and 2, this distribution being moreover managed by the stressing springs 5 and 6 in case of inclination of the balance 3.

Selon un second mode de réalisation représenté sur les figures 4 et 5, le dispositif comprend un balancier 3' qui est asymétrique. Ce balancier porte également un galet 1' de présertissage et un galet 2' de sertissage situés l'un derrière l'autre par rapport au sens de déplacement de l'outil. Ces galets 1' et 2' sont aussi montés sur des axes A1' et A2' formant un angle W' l'un par rapport à l'autre, comme visible dans la figure 5.According to a second embodiment shown on the Figures 4 and 5 , the device comprises a balance 3 'which is asymmetrical. This balance also carries a roller 1 'of présertissage and a roller 2' crimping located one behind the other relative to the direction of movement of the tool. These rollers 1 'and 2' are also mounted on axes A1 'and A2' forming an angle W 'with respect to each other, as visible in FIG. figure 5 .

Comme dans le cas du premier mode de réalisation, l'axe A1' et l'axe A2' sont inscrits dans deux plans parallèles, perpendiculaires à la trajectoire de l'outil. L'angle W' correspond à l'angle séparant, dans le plan contenant l'axe A2', l'axe A2' et la projection orthogonale de l'axe A1' dans ce plan.As in the case of the first embodiment, the axis A1 'and the axis A2' are inscribed in two parallel planes, perpendicular to the path of the tool. The angle W 'corresponds to the angle separating, in the plane containing the axis A2', the axis A2 'and the orthogonal projection of the axis A1' in this plane.

Comme visible dans les figures 4 et 5, le balancier 3' est aussi monté sur une embase repérée par 7' qui est rigidement solidaire d'une tête de sertissage 8' pourvue d'une surface supérieure 9' de fixation à un bras du robot.As visible in Figures 4 and 5 , the balance 3 'is also mounted on a base marked by 7' which is rigidly secured to a crimping head 8 'provided with an upper surface 9' of attachment to an arm of the robot.

Mais dans ce second mode de réalisation, le support 3' est apte à pivoter par rapport à cette embase 7' autour de l'axe A2' coïncidant avec l'axe du galet 2' de sertissage.But in this second embodiment, the support 3 'is pivotable relative to the base 7' about the axis A2 'coinciding with the axis of the roller 2' crimping.

La tête de sertissage 8' des figures 4 et 5 est identique à la tête de sertissage 8 des figures 1 et 2. Elle comprend par exemple un ressort permettant d'ajuster le niveau d'effort appliqué à l'outil en paramétrant la trajectoire du robot pour comprimer plus ou moins fortement ce ressort.The crimping head 8 ' Figures 4 and 5 is identical to the crimping head 8 of Figures 1 and 2 . It comprises for example a spring for adjusting the level of force applied to the tool by setting the path of the robot to compress more or less strongly this spring.

Dans ce second mode de réalisation, l'axe A2' du galet de sertissage 2', et de pivotement du balancier 3' coupe l'axe AX' de symétrie de la tête de sertissage 8', ces deux axes étant inscrits dans un plan normal à la direction de déplacement de l'outil.In this second embodiment, the axis A2 'of the crimping roller 2', and pivoting of the balance 3 'intersects the axis AX' of symmetry of the crimping head 8 ', these two axes being inscribed in a plane normal to the direction of movement of the tool.

En ce qui concerne le galet de présertissage 1', son axe de rotation A1' est situé en avant du plan normal à la trajectoire de l'outil et contenant l'axe AX', de sorte que l'effort appliqué par ce galet de présertissage 1' dépend principalement d'un ressort de mise en contrainte repéré par 5 '.As regards the prestress roller 1 ', its axis of rotation A1' is situated in front of the plane normal to the path of the tool and containing the axis AX ', so that the force applied by this roller of Preservation 1 'mainly depends on a stressing spring marked by 5'.

Comme visible dans les figures 4 et 5, le dispositif comprend une branche latérale unique repérée par 11', s'étendant parallèlement à l'axe AX' et portant le ressort 5'.As visible in Figures 4 and 5 , the device comprises a single lateral branch marked by 11 ', extending parallel to the axis AX' and carrying the spring 5 '.

Cette branche 11' est située en arrière du galet de sertissage 2' par rapport au sens d'avancement de l'outil. Elle comprend une chape à son extrémité inférieure par laquelle elle est reliée à un bras inférieur 12' du support 3' par une liaison pivot d'axe parallèle à l'axe A2'.This branch 11 'is located behind the crimping roller 2' relative to the direction of travel of the tool. It comprises a yoke at its lower end by which it is connected to a lower arm 12 'of the support 3' by a pivot connection axis parallel to the axis A2 '.

Le bras inférieur 12' prolonge une zone de fixation des galets, selon la direction horizontale correspondant à la direction d'avancement de l'outil, et il se termine par un coude orienté verticalement à l'extrémité supérieure duquel est fixée la chape de la branche 11'.The lower arm 12 'extends an attachment zone of the rollers, in the horizontal direction corresponding to the direction of advance of the tool, and ends with a bend oriented vertically at the upper end of which is fixed the yoke of the branch 11 '.

La branche 11' comprend une tige non visible sur les figures et ayant son extrémité inférieure fixée à la chape. Cette tige est parallèle à l'axe AX', et elle traverse une butée tubulaire 13', cette butée étant rigidement fixée à l'embase 7' en s'étendant parallèlement à l'axe AX'.The branch 11 'comprises a rod not visible in the figures and having its lower end fixed to the yoke. This rod is parallel to the axis AX ', and it passes through a tubular abutment 13', this stop being rigidly fixed to the base 7 'extending parallel to the axis AX'.

Le ressort hélicoïdal 5' entoure une vis de tarage 14' qui est vissée dans une extrémité supérieure de la tige non visible. Le ressort 5' est ainsi interposé entre la tête de la vis de tarage 14' et une face supérieure de la butée tubulaire 13'.The helical spring 5 'surrounds a set screw 14' which is screwed into an upper end of the non-visible rod. The spring 5 'is thus interposed between the head of the set screw 14' and an upper face of the tubular abutment 13 '.

Lorsque les efforts appliqués à l'outil tendent à le faire pivoter dans le sens indirect sur la figure 4, c'est-à-dire à faire monter le galet de présertissage 1', ceci tend à comprimer le ressort de mise en contrainte 5', ce qui provoque une augmentation de l'effort appliqué par le galet 1' au bord de tôle à sertir.When the forces applied to the tool tend to rotate it in the indirect direction on the figure 4 , that is to say, to raise the prestress roller 1 ', this tends to compress the stress spring 5', which causes an increase in the force applied by the roller 1 'at the edge of sheet metal Crimp.

La vis de tarage 14' permet ainsi d'ajuster directement l'effort appliqué par le galet de présertissage 1' au bord de tôle à plier, cet effort étant d'autant plus important que la vis 14' est serrée.The set screw 14 'thus makes it possible to directly adjust the force applied by the prestressing roller 1' to the sheet metal edge to be bent, this force being all the more important as the screw 14 'is tightened.

Dans le cas où l'effort à appliquer par le galet de sertissage 2' est très supérieur à celui à appliquer par le galet de présertissage 1', l'ajustement du tarage avec la vis 14' est quasiment sans influence sur l'effort appliqué par le galet de sertissage 2' qui dépend principalement de l'effort appliqué par la tête de sertissage 8'.In the case where the force to be applied by the crimping roller 2 'is much greater than that to be applied by the prestress roller 1', the adjustment of the calibration with the screw 14 'has virtually no influence on the applied force by the crimping roller 2 'which depends mainly on the force applied by the crimping head 8'.

Comme visible en particulier dans la figure 4, la base de la chape 15' de la branche 11' définit une surface d'appui de plus grandes dimensions que la face inférieure de la butée tubulaire 13'.As visible especially in the figure 4 , the base of the clevis 15 'of the branch 11' defines a support surface of larger dimensions than the lower face of the tubular abutment 13 '.

En position de repos, comme dans le cas de la figure 4, la base de cette chape est maintenue en appui sur la face inférieure de la butée 13' par le ressort 5', de sorte que le balancier 3' occupe alors une position angulaire neutre.In the rest position, as in the case of figure 4 , the base of this yoke is held in abutment on the lower face of the abutment 13 'by the spring 5', so that the balance 3 'then occupies a neutral angular position.

Comme illustré sur la figure 3, lors d'un sertissage, le galet de pré sertissage 1' est positionné en appui sur une surface de guidage S de la matrice M dans laquelle ont été positionnés les panneaux de tôle P1 et P2 à sertir, en exerçant un effort sur le bord B1 via l'outil, pour plier ce bord B1 localement.As illustrated on the figure 3 during crimping, the pre-crimping roller 1 'is positioned in abutment on a guide surface S of the matrix M in which the sheet metal panels P1 and P2 to be crimped have been positioned, exerting a force on the edge B1 via the tool, to fold this edge B1 locally.

L'outil est ensuite déplacé le long du bord à sertir, en appui sur la surface de guidage S, de manière à exercer un effort sur le bord B1 à sertir.The tool is then moved along the crimping edge, resting on the guide surface S, so as to exert a force on the edge B1 to be crimped.

L'avance de l'outil provoque le pliage du bord B1 par le galet de pré sertissage 1', puis ce bord B1 est appliqué sur le bord B2 par le galet de sertissage 2'. Le temps de cycle peut ainsi être divisé par deux.The advance of the tool causes the folding of the edge B1 by the pre crimping roller 1 ', then this edge B1 is applied on the edge B2 by the crimping roller 2'. The cycle time can thus be divided by two.

La mobilité du balancier permet d'éviter un marquage des pièces au passage d'un obstacle : un réglage fin de la pression du galet de présertissage pouvant être effectué en jouant sur la vis de tarage 14'.The mobility of the balance makes it possible to avoid marking the pieces when passing an obstacle: a fine adjustment of the pressure of the presetting roller can be performed by adjusting the set screw 14 '.

D'autre part, la programmation de la trajectoire du robot portant l'outil selon le second mode de réalisation est simplifiée par le fait que l'axe A1' portant le galet 1' de présertissage est inscrit dans un plan comprenant l'axe AX' de la tête 8' et l'axe 4' de pivotement du balancier 3'.On the other hand, the programming of the trajectory of the robot carrying the tool according to the second embodiment is simplified by the fact that the axis A1 'carrying the prestressing roller 1' is inscribed in a plane comprising the axis AX 'of the head 8' and the axis 4 'of pivoting of the balance 3'.
