L'invention a également trait à un procédé mis en œuvre par un outillage de sertissage pour établir des trajectoires de déplacement d'une lame de l'outillage.The invention relates to the field of crimping tools. The invention also relates to a method implemented by a crimping tool to establish movement trajectories of a blade of the tool.

La figure 1 est une vue d'un outillage 2 connu de sertissage par pliage de bords d'emboutis (non représentés), notamment d'éléments de carrosserie de véhicule automobile. L'outillage comprend une matrice 4 avec un bord fixe 6 s'étendant longitudinalement ; une lame mobile 8 liée à un bras mobile 10 et apte à être déplacée par ledit bras le long du bord de la matrice. L'outillage est en l'occurrence représenté dans une phase de positionnement de la lame par rapport à la matrice, il comprend un gabarit 12 monté sur la lame pour assurer ce positionnement. Le gabarit comprend une surface de contact avec le bord 6 de la matrice, cette surface formant une première portion 20 généralement plane prenant appui sur la surface supérieure du bord 6 et une deuxième portion 18, également généralement plane, prenant appui sur la face latérale du bord. La première portion de surface 20 se limite à régler la hauteur de la lame sans se soucier de son inclinaison par rapport à la surface supérieure du bord 6.The figure 1 is a view of a known tool 2 for crimping by folding stamped edges (not shown), in particular motor vehicle bodywork elements. The tool comprises a die 4 with a fixed edge 6 extending longitudinally; a movable blade 8 linked to a movable arm 10 and able to be moved by said arm along the edge of the die. The tool is in this case represented in a phase of positioning the blade with respect to the matrix, it comprises a template 12 mounted on the blade to ensure this positioning. The template comprises a contact surface with the edge 6 of the die, this surface forming a first generally flat portion 20 resting on the upper surface of the edge 6 and a second portion 18, also generally flat, resting on the side face of the edge. The first surface portion 20 is limited to adjusting the height of the blade without worrying about its inclination with respect to the upper surface of the edge 6.

De plus, cet enseignement n'est satisfaisant que lorsque le bord de la matrice est généralement rectiligne en raison de l'interférence des zones latérales à la deuxième portion de surface 18. Un outillage de sertissage similaire à celui de la figure 1 est décrit dans le document FR-A-2987289 sur lequel repose le préambule de la revendication 1.Moreover, this teaching is satisfactory only when the edge of the die is generally rectilinear due to the interference of the lateral zones with the second surface portion 18. A crimping tool similar to that of the figure 1 is described in the document FR-A-2987289 on which the preamble of claim 1 is based.

L'invention a également pour objet un procédé de mise au point de trajectoire d'une lame mobile de sertissage par pliage de bords d'emboutis ; remarquable en ce qu'il comprend l'utilisation d'un outillage de sertissage conforme à l'invention, et comprend les étapes suivantes : i) déplacement de la lame mobile, équipée de la première cale, le long de la surface d'appui de la matrice en l'absence du ou des emboutis, la hauteur (h) de ladite cale, entre la surface de contact de la lame et la surface d'appui de la matrice correspondant à la hauteur des bords d'embouti(s) sertis ; ii) détection d'écarts de positionnement entre la première cale et la surface d'appui de la matrice ; iii) correction des écarts de positionnement par translation(s) et/ou pivotement(s) d'un bras mobile supportant la lame.The invention also relates to a method for developing the trajectory of a mobile crimping blade by folding stamped edges; remarkable in that it comprises the use of a crimping tool according to the invention, and comprises the following steps: i) displacement of the movable blade, equipped with the first wedge, along the bearing surface of the die in the absence of the stamping(s), the height (h) of said wedge, between the contact surface of the blade and the support surface of the die corresponding to the height of the edges of the stamping(s) crimped; ii) detection of positioning deviations between the first wedge and the support surface of the die; iii) correction of positioning deviations by translation(s) and/or pivoting(s) of a movable arm supporting the blade.

Selon un mode avantageux de l'invention, le procédé comprend, en outre, une étape, précédant l'étape de déplacement, d'application d'une couche de pigment coloré sur la surface d'appui et/ou sur la surface latérale de la matrice, la détection d'écarts de positionnement de la lame étant basée sur l'observation de zones de non frottement ou frottement insuffisant sur ladite couche de pigment.According to an advantageous mode of the invention, the method further comprises a step, preceding the moving step, of applying a layer of colored pigment on the support surface and/or on the side surface of the matrix, the detection of deviations in the positioning of the blade being based on the observation of zones of no friction or insufficient friction on said layer of pigment.

Selon un mode avantageux de l'invention, le procédé comprend, en outre, la mise en place d'un ou plusieurs comparateurs sur la lame afin de mesurer des distances transversalement à la direction de déplacement de la lame mobile et/ou la mise en place d'un indicateur de pente sur la lame, afin d'être lié à la lame pour mesurer des angles de pivotement de ladite lame. Le gabarit peut comprendre un support de comparateur avec des moyens de fixation, notamment par vissage, à la lame mobile. Le support peut comprendre un ou plusieurs orifices transversaux, préférentiellement perpendiculaires, à la direction de déplacement de la lame mobile, ces orifices étant configurés pour supporter le ou les comparateurs.

En effet, l'outillage comprend un gabarit avec une surface de contact latéral sur la deuxième cale et une surface de contact supérieure sur la première cale, ces surfaces étant configurées pour glisser sur le bord de la matrice lors du déplacement de la lame le long du bord en vue de son positionnement. Les surfaces de contact s'étendent transversalement par rapport à la direction longitudinale du bord et de la lame et les écarts de positionnement de la lame ne produisant pas de contact contre le bord peuvent être détectés et corrigés par déplacement d'un bras mobile portant la lame. Les surfaces de contact, en particulier peuvent être disposées longitudinalement de manière adaptée pour le sertissage, en particulier pour le pliage et de pressage du bord d'embouti contre le bord de la matrice. Des bords d'embouti courbés et/ou galbés, notamment d'éléments de carrosserie de véhicule automobile peuvent être sertis simplement par un tel outillage.According to an advantageous embodiment of the invention, the method further comprises placing one or more comparators on the blade in order to measure distances transversely to the direction of movement of the moving blade and/or placing place of a slope indicator on the blade, in order to be linked to the blade to measure the angles of pivoting of said blade. The jig can comprise a comparator support with fixing means, in particular by screwing, to the movable blade. The support may comprise one or more transverse orifices, preferably perpendicular to the direction of movement of the movable blade, these orifices being configured to support the comparator or comparators. The invention is interesting in that the crimping tool is adapted to easily establish a trajectory of the crimping blade along a fixed edge of the die. Indeed, the tooling comprises a jig with a side contact surface on the second wedge and an upper contact surface on the first wedge, these surfaces being configured to slide on the edge of the die during movement of the blade along edge for positioning. The contact surfaces extend transversely with respect to the longitudinal direction of the edge and of the blade and deviations in the positioning of the blade which do not produce contact against the edge can be detected and corrected by movement of a mobile arm carrying the blade. The contact surfaces in particular can be arranged longitudinally suitable for crimping, in particular for bending and pressing the stamped edge against the edge of the die. Curved and/or curved deep-drawn edges, in particular of motor vehicle bodywork elements, can be crimped simply by such a tool.

In the crimping phase, the blade carries out in this movement the bending and the pressing of an edge of a stamping against the stamping in question against the edge of another stamping, resting on the edge of the die. It comprises a twist-shaped left surface along the longitudinal direction for gradual bending of the stamped edge during movement; the spiral-shaped surface ends in a surface portion intended to press the stamped edge. The fixed edge 106 includes a side surface 114 and a bearing surface 116 adjacent to the side surface. The bearing surface is intended to receive the edge(s) of the stamping(s).

La figure 2 présente aussi deux vues en coupe transversale «T1» et «T2» de l'outillage par rapport à la direction longitudinale « L ».The figure 2 also presents two cross-sectional views "T1" and "T2" of the tool with respect to the longitudinal direction "L".

En référence à ces vues en coupe de la figure 2, l'outillage comprend aussi un gabarit 112 monté sur la lame, le gabarit étant prévu pour positionner la lame par rapport au bord fixe le long de son déplacement. Le gabarit comprend une première cale 1121 avec une surface de contact 120 apte à prendre appui contre la surface d'appui 116 du bord fixe. Le gabarit 112 comprend également une deuxième cale 1122 avec une surface de contact latéral 118 apte à prendre appui contre la surface latérale 114 du bord. La surface de contact 120 s'étend transversalement à la direction longitudinale et est à distance de la surface de contact latéral 118 selon la direction longitudinale « L ».With reference to these sectional views of the figure 2 , the tool also comprises a template 112 mounted on the blade, the template being provided to position the blade relative to the fixed edge along its movement. The jig comprises a first wedge 112 1 with a contact surface 120 capable of bearing against the bearing surface 116 of the fixed edge. The template 112 also includes a second wedge 112 2 with a lateral contact surface 118 capable of bearing against the lateral surface 114 of the edge. The contact surface 120 extends transversely to the longitudinal direction and is at a distance from the lateral contact surface 118 in the longitudinal direction "L".

On peut voir sur la vue en coupe « T1 » de la figure 2 la deuxième cale 1122 du gabarit 112, comprenant la surface de contact latéral 118 s'étendant transversalement et épousant la surface latérale 114 du bord. La surface latérale s'étend transversalement selon la direction «K» orthogonale à la direction longitudinale.You can see on the "T1" sectional view of the picture 2 the second wedge 112 2 of the template 112, comprising the lateral contact surface 118 extending transversely and matching the lateral surface 114 of the edge. The side surface extends transversely along the direction "K" orthogonal to the longitudinal direction.

On peut voir sur la vue en coupe «T2» de la figure 2 la première cale 1121 du gabarit 112, comprenant la surface de contact supérieur 120 s'étendant transversalement et épousant la surface d'appui 116 du bord qui est adjacente à la surface latérale.You can see on the "T2" sectional view of the picture 2 the first wedge 112 1 of the template 112, comprising the upper contact surface 120 extending transversely and marrying the bearing surface 116 of the edge which is adjacent to the side surface.

Si on considère le sens de déplacement de la lame indiqué par la flèche sur l'image principale de la figure 2, la vue en coupe « T2 » présentant la surface de contact 120 de la première cale est située en amont par rapport à la vue en coupe «T1» présentant la surface de contact latéral. Aussi, les surfaces de contact latéral et supérieur « s'étendant transversalement » doivent s'entendre qu'elles s'étendent principalement dans une direction transversale. Les surfaces de contact latéral et supérieur peuvent former des contacts transversaux linéiques.If we consider the direction of movement of the blade indicated by the arrow on the main image of the picture 2 , the cross-sectional view “T2” presenting the contact surface 120 of the first wedge is located upstream with respect to the cross-sectional view “T1” presenting the lateral contact surface. Also, the "transversely extending" side and top contact surfaces are to be understood to extend primarily in a transverse direction. The side and top contact surfaces can form line transverse contacts.

Revenant sur la vue en coupe «T1» de la figure 2, on peut voir la lame mobile s'étendant longitudinalement qui comprend une surface gauche en forme de vrille 122 le long de la direction longitudinale « L ». La surface vrillant est destinée à plier le bord d'embouti, en particulier la surface de contact latéral est située longitudinalement au niveau de la surface vrillant formant un angle de pliage β moyen compris entre 20° et 70° par rapport à la surface supérieure, préférentiellement compris entre 30° et 60°, plus préférentiellement compris entre 40° et 50°. Cette mesure de l'invention est intéressante en ce que la surface de contact latéral 118 est située longitudinalement à un niveau ou la précision de positionnement latérale de la surface vrillant vis-à-vis du bord de la matrice doit être adaptée pour assurer un pliage au niveau adapté du bord d'embouti.Returning to the "T1" sectional view of the picture 2 , one can see the movable longitudinally extending blade which includes a twist-shaped left surface 122 along the longitudinal direction "L". The twisting surface is intended to bend the stamped edge, in particular the lateral contact surface is located longitudinally at the level of the twisting surface forming an average bending angle β of between 20° and 70° with respect to the upper surface, preferably between 30° and 60°, more preferably between 40° and 50°. This measure of the invention is interesting in that the lateral contact surface 118 is located longitudinally at a level where the lateral positioning precision of the twisting surface with respect to the edge of the die must be adapted to ensure bending. at the appropriate level of the stamped edge.

Revenant à la vue en coupe « T2 », on peut voir la surface vrillant qui se termine par une portion de surface arrière 124 destinée à presser le bord d'embouti contre la surface d'appui 116 du bord. En particulier, la surface de contact supérieur 120 est située longitudinalement au niveau de cette portion 124 destinée à presser l'embouti. Cette mesure de l'invention est très intéressante pour assurer un positionnement adapté à ce niveau longitudinal de la lame ; la surface de contact supérieur 120 est située longitudinalement à un niveau ou la précision de positionnement de la lame vis-à-vis du bord de la matrice doit être adapté pour le pressage du bord de l'embouti en fin de sertissage. La surface de contact supérieur 120 s'étend en l'occurrence latéralement sur une distance « D » supérieure à 2mm, préférentiellement supérieure à 4mm, plus préférentiellement encore supérieure à 6mm. La distance « D » correspond avantageusement à plus 80% de la largeur moyenne de la surface d'appui 116. Cette mesure de l'invention est intéressante en ce que la surface de contact supérieur 120 peut être en contact avec la surface d'appui 116 du bord sur une distance correspondant à celle de la largeur d'un bord d'embouti destiné à être pressé en fin de sertissage. En particulier, la première cale comprend, en outre, une surface d'appui 126 en contact avec la lame mobile 108 et qui est située à l'opposé de la surface de contact supérieur 120. Cette mesure de l'invention est intéressante pour assurer une rigidité de la cale au niveau de la surface de contact supérieur. En particulier, la surface d'appui 126 peut s'étendre transversalement et être en appui contre la portion de surface arrière 124 de la surface vrillant et destinée à presser le bord d'embouti. Cette mesure de l'invention est particulièrement intéressante en ce que la hauteur entre la surface de contact supérieur 120 et la surface d'appui 126 peut précisément correspondre à une distance cible adaptée entre la portion 124 de la lame en question et la surface d'appui 116 au moment du pressage en fin de sertissage. La hauteur « h » entre la surface d'appui 126 et la surface de contact supérieur 120 peut être comprise entre 1mm et 8mm, préférentiellement entre 1,5mm et 6mm, plus préférentiellement encore entre 2mm et 4mm. Il est à noter que cette distance correspond généralement à 3 fois l'épaisseur de l'embouti, c'est-à-dire à la somme des épaisseurs de tôles serties, soit, en général, 2 fois la peau + 1 fois la doublure, à laquelle peut être soustrait un jeu correspondant à l'écrasement lors du pressage en fin sertissage.Returning to the sectional view “T2”, one can see the twisting surface which ends in a rear surface portion 124 intended to press the stamped edge against the bearing surface 116 of the edge. In particular, the upper contact surface 120 is located longitudinally at the level of this portion 124 intended to press the stamped part. This measure of the invention is very interesting to ensure a suitable positioning at this longitudinal level of the blade; the upper contact surface 120 is located longitudinally at a level where the positioning accuracy of the blade vis-à-vis the edge of the die must be suitable for pressing the edge of the stamping at the end of crimping. The upper contact surface 120 in this case extends laterally over a distance “D” greater than 2 mm, preferably greater than 4 mm, more preferably still greater than 6 mm. The distance "D" advantageously corresponds to more than 80% of the width average of the support surface 116. This measurement of the invention is interesting in that the upper contact surface 120 can be in contact with the support surface 116 of the edge over a distance corresponding to that of the width of a stamped edge intended to be pressed at the end of crimping. In particular, the first wedge further comprises a bearing surface 126 in contact with the movable blade 108 and which is located opposite the upper contact surface 120. This measure of the invention is advantageous for ensuring rigidity of the wedge at the level of the upper contact surface. In particular, the bearing surface 126 can extend transversely and bear against the rear surface portion 124 of the twisting surface and intended to press the stamped edge. This measurement of the invention is particularly interesting in that the height between the upper contact surface 120 and the support surface 126 can precisely correspond to a suitable target distance between the portion 124 of the blade in question and the surface of support 116 at the time of pressing at the end of crimping. The height “h” between the support surface 126 and the upper contact surface 120 can be between 1mm and 8mm, preferably between 1.5mm and 6mm, more preferably still between 2mm and 4mm. It should be noted that this distance generally corresponds to 3 times the thickness of the stamping, that is to say the sum of the thicknesses of crimped sheets, i.e., in general, 2 times the skin + 1 time the lining , from which can be subtracted a game corresponding to the crushing during pressing at the end of crimping.

Le procédé conforme à l'invention est prévu pour établir des trajectoires de la lame mobile 108 s'étendant longitudinalement le long du bord fixe. Le procédé est mis en œuvre par l'outillage de sertissage 102 conforme à l'invention et comprend les étapes suivantes : a) déplacement de la lame mobile longitudinale 108 le long du bord fixe 106, la surface de contact latéral 118 glissant le long de la surface latérale 114 du bord et/ou la surface de contact supérieur 120 épousant et glissant le long de la surface d'appui 116 dudit bord. ; b) détection d'écarts de positionnement entre la surface de contact latéral vis-à-vis de la surface latérale du bord et/ou entre la surface de contact supérieur vis à vis de la surface d'appui du bord ; c) correction d'écarts de positionnement par translation(s) et/ou pivotement(s) du bras mobile 110.The method according to the invention is provided for establishing trajectories of the mobile blade 108 extending longitudinally along the fixed edge. The method is implemented by the crimping tool 102 in accordance with the invention and comprises the following steps: a) displacement of the longitudinal movable blade 108 along the fixed edge 106, the lateral contact surface 118 sliding along the side surface 114 of the edge and/or the upper contact surface 120 matching and sliding along the bearing surface 116 of said edge. ; b) detection of positioning deviations between the lateral contact surface with respect to the lateral surface of the edge and/or between the upper contact surface with respect to the support surface of the edge; c) correction of positioning deviations by translation(s) and/or pivoting(s) of the movable arm 110.

La figure 3 est une vue de la matrice 104 après l'étape de déplacement du procédé conforme à l'invention. En l'occurrence, l'image présente en particulier, le bord fixe 106 de la matrice. En particulier, le procédé, dans un mode préféré de réalisation, comprend, en outre, une étape, précédant le déplacement, d'application d'une couche de pigment coloré 128, tel que du bleu de Prusse, sur la surface latérale 114 du bord fixe et/ou sur la surface d'appui 116 du bord fixe. On peut voir en l'occurrence sur l'image une couche de pigment sur la surface d'appui 116 du bord de la matrice (voir les petits traits symbolisant la couche). Le déplacement de la lame mobile avec les surfaces de contact latéral et/ou supérieur contactant les surfaces correspondantes du bord, génère un frottement sur la couche de pigment au niveau de zones de contact ; le retrait de la couche de pigment est une indication visible d'un positionnement correct de la lame vis-à-vis du bord. En l'occurrence, la mesure d'écarts de positionnement de la lame est réalisée par référence aux zones de non frottement des surfaces de contact latéral et ou supérieur avec la couche de pigment, zones sur lesquelles la couche de pigment n'est pas retirée.The picture 3 is a view of the die 104 after the displacement step of the method according to the invention. In this case, the image has in particular the fixed edge 106 of the matrix. In particular, the method, in a preferred embodiment, further comprises a step, preceding the displacement, of applying a layer of colored pigment 128, such as Prussian blue, on the side surface 114 of the fixed edge and/or on the bearing surface 116 of the fixed edge. One can see in this case on the image a layer of pigment on the bearing surface 116 of the edge of the matrix (see the small lines symbolizing the layer). The movement of the movable blade with the lateral and/or upper contact surfaces contacting the corresponding surfaces of the edge, generates friction on the layer of pigment at the contact zones; the removal of the pigment layer is a visible indication of the correct positioning of the blade vis-à-vis the edge. In this case, the measurement of blade positioning deviations is carried out by reference to the non-friction zones of the lateral and or upper contact surfaces with the layer of pigment, zones on which the layer of pigment is not removed. .

On peut voir, à titre d'exemple, à droite de l'image une première zone « U » de la surface supérieure de la matrice vis-à-vis de laquelle le positionnement de la lame lors du déplacement est adapté. En effet, le pigment est retiré sur toute la largeur « I » de la surface supérieure 116. La distance « I » doit correspondre à la distance D (vue en référence à la figure 2). Il est à noter qu'il peut être recherché de contrôler le pivotement de la lame par rapport à un axe perpendiculaire à la surface supérieure et le long du déplacement de la lame. En effet, la limite 130 d'enlèvement du pigment formant une ligne régulièrement à distance de la carre du bord peut servir de témoin du pivotement adapté de la lame le long du bord. La carre correspond à l'arête joignant les surfaces latérale et supérieure du bord.One can see, by way of example, on the right of the image a first “U” zone of the upper surface of the die vis-à-vis which the positioning of the blade during movement is adapted. Indeed, the pigment is removed over the entire width "I" of the upper surface 116. The distance "I" must correspond to the distance D (seen with reference to the picture 2 ). It should be noted that it may be desired to control the pivoting of the blade with respect to an axis perpendicular to the upper surface and along the movement of the blade. Indeed, the limit 130 of removal of the pigment forming a line regularly at a distance from the edge of the edge can serve as a witness of the adapted pivoting of the blade along the edge. The edge is the ridge joining the side and top surfaces of the edge.

On peut voir, encore à titre d'exemple, au milieu de l'image, une deuxième zone « V » de la surface supérieure du bord vis-à-vis de laquelle le positionnement de la lame lors du déplacement n'est pas adapté. En effet, le pigment n'est retiré que sur une partie de la largeur de la surface supérieure, en l'occurrence une partie adjacente à la carre du bord. La correction de cet écart se fait par correction de la trajectoire du bras mobile portant la lame. Cette correction peut consister en l'occurrence en un pivotement de la lame sur le tronçon du déplacement de la lame en vis-à-vis de cette deuxième zone.We can see, again by way of example, in the middle of the image, a second zone "V" of the upper surface of the edge vis-à-vis which the positioning of the blade during movement is not adapted . Indeed, the pigment is removed only on a part of the width of the upper surface, in this case a part adjacent to the edge of the edge. This deviation is corrected by correcting the trajectory of the movable arm carrying the blade. This correction may consist in this case of a pivoting of the blade on the section of the movement of the blade vis-à-vis this second zone.

On peut voir, encore à titre d'exemple, à gauche de l'image, une troisième zone « W » de la surface supérieure du bord vis-à-vis de laquelle le positionnement de la lame lors du déplacement n'est pas non plus adapté. En effet, le pigment n'est retiré que sur une partie de la largeur de la surface supérieure, en l'occurrence une partie à distance de la carre du bord. La correction de cet écart se fait aussi par correction de la trajectoire du bras mobile portant la lame. Cette correction peut consister en l'occurrence à un pivotement de la lame sur le tronçon du déplacement de la lame en vis-à-vis de cette troisième zone, le pivotement devant être ici réalisé dans le sens opposé à celui mentionné en référence à la deuxième zone « V » de la surface supérieure.We can see, again by way of example, on the left of the image, a third zone "W" of the upper surface of the edge vis-à-vis which the positioning of the blade during movement is not either more adapted. Indeed, the pigment is only removed over a part of the width of the upper surface, in this case a part away from the edge of the edge. This deviation is also corrected by correcting the trajectory of the movable arm carrying the blade. This correction can consist in this case in a pivoting of the blade on the section of the movement of the blade vis-à-vis this third zone, the pivoting having to be carried out here in the direction opposite to that mentioned with reference to the second zone "V" of the upper surface.

La figure 4 est une vue en perspective de la lame 108 et du gabarit 112 de l'outillage conforme à l'invention. On peut observer les première et deuxième cales 1121 et 1122 formant des éléments distincts rapportées sur la lame. Cette mesure est intéressante pour faciliter l'usinage des surfaces de contact. En l'occurrence, on peut voir que la surface de contact latéral 118 et la surface de contact supérieur 120 sont formées par des portions cylindriques réalisées dans chacune des cales. Les surfaces de contact supérieur et latéral peuvent en l'occurrence être de rayon supérieur à 5mm et inférieur à 15mm. On peut observer la surface vrillant 122 dans la direction longitudinale « L ». On peut voir sur la zone agrandie de la première cale située sous l'image principale, la surface de contact supérieur 120 ainsi que la surface d'appui 126 contre la portion arrière 124 de la surface vrillant de la lame destiné à presser le bord d'embouti. La première cale peut être symétrique de manière à se monter sur une vrille ou sur sa symétrie. A cet effet, on peut prévoir un chanfrein de chaque côté de la surface 126.The figure 4 is a perspective view of the blade 108 and the jig 112 of the tool according to the invention. One can observe the first and second shims 112 1 and 112 2 forming separate elements attached to the blade. This measure is interesting to facilitate the machining of the contact surfaces. In this case, it can be seen that the lateral contact surface 118 and the upper contact surface 120 are formed by cylindrical portions made in each of the wedges. The upper and lateral contact surfaces may in this case have a radius greater than 5mm and less than 15mm. The twisting surface 122 can be observed in the longitudinal direction "L". One can see on the enlarged area of the first wedge located under the main image, the upper contact surface 120 as well as the bearing surface 126 against the rear portion 124 of the twisting surface of the blade intended to press the edge of stamped. The first wedge can be symmetrical so as to be mounted on a spin or on its symmetry. For this purpose, a chamfer can be provided on each side of the surface 126.

Le gabarit peut comprendre un support de comparateur (non représenté) avec des moyens de fixation, notamment par vissage, à la lame mobile. Le support peut comprendre un ou plusieurs orifices transversaux, préférentiellement perpendiculaires, à la direction de déplacement de la lame mobile, ces orifices étant configurés pour supporter le ou les comparateurs.The jig can comprise a comparator support (not shown) with fixing means, in particular by screwing, to the movable blade. The support may comprise one or more transverse orifices, preferably perpendicular to the direction of movement of the movable blade, these orifices being configured to support the comparator or comparators.
