Description

OUTILLAGE DE PRESSE D'EMBOUTISSAGE A REMONTEE SECURISEE DU COULISSEAU A CAME  TOOLING OF PRESSING PRESS WITH SAFE RISE OF THE CAM SLIDER
[0001] La présente invention concerne un outillage de presse d'emboutissage permettant de réaliser des opérations techniques sur une pièce de tôlerie. [0002] Elle s'applique en particulier, mais de manière non limitative, à l'emboutissage de pièces de structures de carrosseries de véhicules automobiles. The present invention relates to a press stamping tool for performing technical operations on a sheet metal part. It applies in particular, but not limited to stamping parts of automotive body structures.
[0003] On connaît un outillage de presse d'emboutissage comprenant un bâti supérieur verticalement mobile relativement à un bâti inférieur, un premier coulisseau à came inférieure en rampe monté verticalement mobile de manière guidée au bâti inférieur, un second coulisseau inférieur, dénommé boisseau, à came en rampe et monté mobile de manière guidée au bâti inférieur. [0003] A stamping press tooling is known comprising a vertically movable upper frame relative to a lower frame, a first lower cam ramp mounted vertically movably guided to the lower frame, a second lower slider, referred to as a bushel, with a ramp cam and mounted movably guided to the lower frame.
[0004] Le second coulisseau porte à son extrémité opposée à la came en rampe un outil de travail permettant de réaliser des opérations techniques sur une pièce de tôlerie, la came en rampe du second coulisseau coopérant avec la came en rampe du premier coulisseau pour déplacer en translation horizontale le second coulisseau vers la pièce de tôlerie lorsque le premier coulisseau est verticalement abaissé par le bâti supérieur descendant vers le bâti inférieur. The second slide carries at its end opposite to the ramp cam a working tool for performing technical operations on a sheet metal part, the ramp cam of the second slide cooperating with the ramp cam of the first slide to move in horizontal translation the second slide to the sheet metal part when the first slide is vertically lowered by the upper frame descending to the lower frame.
[0005] Un vérin, par exemple du type à gaz, est interposé verticalement entre le bâti inférieur et le premier coulisseau pour assurer la remontée de ce dernier lorsque le bâti supérieur de la presse remonte une fois la pièce de tôlerie emboutie. A cylinder, for example of the gas type, is interposed vertically between the lower frame and the first slide to ensure the recovery of the latter when the upper frame of the press back once the sheet metal part stamped.
[0006] Cependant, le vérin de remontée du premier coulisseau, au bout d'un certain nombre d'opérations d'emboutissage, peut subir une perte de pression ou dégonflement empêchant la remontée de ce coulisseau, impliquant alors l'annulation de la transformation de la pièce de tôlerie, l'arrêt de la production et le démontage de l'outillage pour intervention. However, the lift cylinder of the first slide, after a number of stamping operations, can suffer a loss of pressure or deflation preventing the ascent of the slide, thus implying the cancellation of the transformation of the sheet metal part, the stop of the production and the disassembly of the tools for intervention.
[0007] En outre, il y a également un risque de grippage du premier coulisseau, occasionnant alors un très grand risque de sécurité pour l'opérateur devant assurer une intervention périlleuse de déblocage de ce coulisseau. [0008] Enfin, la remontée accidentelle seule du premier coulisseau, c'est-à-dire non accompagnée par le bâti supérieur dans le cycle de presse engendre généralement de très lourds dégâts dans l'outillage se traduisant par des délais de réparation longs et coûteux avec perturbation du flux de fabrication des pièces de tôlerie. [0009] La présente invention a pour but de palier les inconvénients ci-dessus de l'outillage de presse d'emboutissage connu. In addition, there is also a risk of seizure of the first slide, thus causing a very high security risk for the operator to ensure a perilous unlocking action of the slider. Finally, accidental winding only of the first slide, that is to say, not accompanied by the upper frame in the press cycle generally generates very heavy damage in the tooling resulting in long repair times and costly with disruption of manufacturing flow of sheet metal parts. The present invention aims to overcome the above drawbacks of the known stamping press tooling.

[0013] La face frontale de la butée et la face plane du bossage du bras pivotant sont en contact l'une avec l'autre suivant une même hauteur verticale à la position de maintien de l'extrémité en forme de crochet dans l'encoche du bloc de commande. Preferably, the locking member comprises a hook-shaped end arm pivotally mounted to the first slider about a horizontal axis integral with the first slider and pivotable to its locking position of the first slider to the slider block. control under the action of an abutment secured to the upper frame and to which the hook-shaped end is engaged and held in a notch of the control block by the abutment bearing on the pivoting arm when the upper frame substantially reaches its bottom dead position. Advantageously, the abutment comprises a vertical end face bearing on a flat front face of an external boss of the pivoting arm to engage and maintain the hook-shaped end of the pivoting arm in the notch of the control block. . The front face of the abutment and the flat face of the boss of the pivoting arm are in contact with each other following the same vertical height at the holding position of the hook-shaped end in the notch from the control block.

[0015] Le premier coulisseau comprend un organe de déverrouillage libérant l'organe de verrouillage de sa position de verrouillage de ce coulisseau au bloc de commande lorsque le bâti supérieur atteint une hauteur déterminée lors de sa remontée. The end face of the abutment is delimited by two upper and lower chamfers and the flat face of the boss of the pivoting arm is delimited by two upper and lower chamfers, the lower bevel of the boss cooperating with the upper chamfer of the abutment. one part during the descent of the upper frame to initiate the pivoting of the arm to its locking position and secondly during the ascent of the upper frame to initiate the pivoting of the arm to its unlocked position. The first slide comprises an unlocking member releasing the locking member from its locking position of the slide to the control block when the upper frame reaches a determined height during its ascent.

[0022] L'outillage de presse d'emboutissage comprend également un premier coulisseau 5 monté verticalement mobile au bâti inférieur 3 par l'intermédiaire de moyens de guidage connus en soi, tels que par exemple des glissières. [0023] Le premier coulisseau 5 porte à son extrémité inférieure une came en rampe 6. The stamping press tool also comprises a first slider 5 mounted vertically movable to the lower frame 3 by means of guide means known per se, such as for example slides. The first slider 5 carries at its lower end a cam ramp 6.
[0024] L'outillage de presse d'emboutissage 1 comprend en outre un second coulisseau inférieur 7, dénommé boisseau, monté mobile au bâti inférieur 3 par l'intermédiaire de moyens de guidage en translation, connus en soi, tels que par exemple des glissières, et permettant le coulissement guidé du second coulisseau 7 suivant une direction horizontale. [0025] Le second coulisseau 7 comporte une came en rampe 8 à l'une de ses extrémités et porte à son extrémité opposée un outil de travail, non représenté, permettant de réaliser des opérations techniques sur une pièce de tôlerie, telles que par exemple une opération de poinçonnage ou une opération de détourage de cette pièce. [0026] La came en rampe 8 du second coulisseau 7 coopère avec la came en rampe 6 du premier coulisseau 5 pour déplacer le second coulisseau 7 vers la pièce de tôlerie lorsque le premier coulisseau 5 est verticalement abaissé par le bâti supérieur 2 descendant vers le bâti inférieur 3 à partir de sa position d'ouverture de l'outillage de presse 1 pour permettre à l'outil de travail d'effectuer l'opération technique appropriée sur la pièce de tôlerie. The pressing press tooling 1 further comprises a second lower slider 7, called plug, movably mounted to the lower frame 3 by means of translation guide means, known per se, such as for example slides, and allowing the guided sliding of the second slider 7 in a horizontal direction. The second slider 7 comprises a cam ramp 8 at one of its ends and carries at its opposite end a working tool, not shown, for performing technical operations on a sheet metal part, such as for example a punching operation or a trimming operation of this piece. The ramped cam 8 of the second slider 7 cooperates with the ramped cam 6 of the first slider 5 to move the second slider 7 to the sheet metal part when the first slider 5 is vertically lowered by the upper frame 2 descending towards the lower frame 3 from its open position of the press tool 1 to allow the work tool to perform the appropriate technical operation on the sheet metal part.
[0027] Le second coulisseau 7 est représenté comme pouvant être déplacé en translation horizontale au bâti inférieur, mais il peut être déplacé en translation inclinée relativement à ce bâti suivant le type d'opération technique à effectuer sur la pièce de tôlerie par l'outil de travail. [0028] Un vérin V, par exemple du type à gaz, est interposé verticalement entre le bâti inférieur 3 et le premier coulisseau 5 pour permettre, dans des conditions normales de fonctionnement du premier coulisseau, la remontée de ce coulisseau pendant la remontée du bâti supérieur 2. The second slider 7 is shown as being movable in horizontal translation to the lower frame, but it can be moved in inclined translation relative to this frame according to the type of technical operation to be performed on the sheet metal part by the tool working. A cylinder V, for example of the gas type, is interposed vertically between the lower frame 3 and the first slider 5 to allow, under normal operating conditions of the first slider, the ascent of the slider during the ascent of the frame superior 2.
[0029] Selon l'invention, le bâti supérieur 2 comprend un bloc 9 de commande du déplacement vertical du premier coulisseau 5 et qui est amoviblement fixé, par exemple par des vis de fixation, non représentées, à une face horizontale 10 du bâti supérieur 2 en s'étendant sous celle-ci suivant une direction verticale au-dessus d'une face plane supérieure horizontale 11 du premier coulisseau 5. According to the invention, the upper frame 2 comprises a block 9 for controlling the vertical displacement of the first slider 5 and which is removably fixed, for example by fastening screws, not shown, to a horizontal face 10 of the upper frame 2 extending below it in a vertical direction above a horizontal upper planar face 11 of the first slider 5.
[0030] Le bloc de commande 9 comporte dans l'une de ses faces latérales une encoche 12 dont le rôle sera expliqué ultérieurement. The control block 9 has in one of its lateral faces a notch 12 whose role will be explained later.
[0031] Le premier coulisseau 5 comprend un organe commandé 13 permettant de verrouiller le premier coulisseau 5 au bloc de commande du bâti supérieur 2 lorsque ce dernier atteint sensiblement sa position de point mort bas d'emboutissage de la pièce de tôlerie, l'organe de verrouillage 13 étant maintenu à sa position de verrouillage du coulisseau 5 au bloc de commande 9 lors de la remontée du bâti supérieur 2 jusqu'à une hauteur déterminée. [0032] De préférence, l'organe de verrouillage 13 comprend un bras 14 à extrémité en forme de crochet 15, monté pivotant à une face latérale et verticale correspondante du coulisseau 5 et apte à pivoter relativement au coulisseau sous l'action d'une butée 16 solidaire du bâti inférieur 3 à une position de verrouillage du coulisseau 5 au bloc de commande 9, à laquelle position l'extrémité en forme de crochet 15 du bras 14 est engagée et maintenue dans l'encoche 12 par la butée 16 en appui sur le bras pivotant 14 lorsque le bâti supérieur 2 atteint sensiblement sa position de point mort bas. The first slider 5 comprises a controlled member 13 for locking the first slider 5 to the control block of the upper frame 2 when the latter substantially reaches its position of bottom dead center stamping of the sheet metal part, the body locking 13 being maintained in its locking position of the slider 5 to the control block 9 during the ascent of the upper frame 2 to a predetermined height. Preferably, the locking member 13 comprises an arm 14 with a hook-shaped end 15 pivotally mounted to a corresponding lateral and vertical face of the slide 5 and able to pivot relative to the slide under the action of a abutment 16 secured to the lower frame 3 at a locking position of the slider 5 to the control block 9, at which position the hook-shaped end 15 of the arm 14 is engaged and held in the notch 12 by the abutment 16 in support on the pivoting arm 14 when the upper frame 2 substantially reaches its bottom dead position.
[0033] Le bras 14 est monté pivotant au premier coulisseau 5 par l'intermédiaire d'un axe horizontal 17 traversant une partie d'extrémité inférieure du bras opposée à l'extrémité supérieure en forme de crochet 15 de ce bras et solidaire d'une chape de support 18 amoviblement fixée, par exemple par des vis de fixation non représentées, à la face latérale correspondante du premier coulisseau 5. The arm 14 is pivotally mounted to the first slider 5 via a horizontal axis 17 passing through a lower end portion of the arm opposite the hook-shaped upper end 15 of this arm and secured to a support screed 18 removably fixed, for example by unrepresented fixing screws, to the corresponding lateral face of the first slide 5.
[0034] Le bras pivotant 14 comprend un bossage externe 19 comportant une face frontale plane 20 délimitée, en considérant le bras 14 à une position sensiblement verticale, par deux chanfreins supérieur 21 et inférieur 22. The pivoting arm 14 comprises an outer boss 19 having a planar front face 20 delimited, considering the arm 14 to a substantially vertical position, by two upper and lower chamfers 21 and 22.
[0035] Le premier coulisseau 5 comprend également un organe 23 permettant le pivotement du bras 14 à sa position de déverrouillage du bloc de commande 9 du premier coulisseau 5. The first slider 5 also comprises a member 23 for pivoting the arm 14 to its unlocking position of the control block 9 of the first slider 5.
[0036] De préférence, l'organe de déverrouillage 23 est constitué par un vérin horizontal, par exemple du type à gaz, dont le cylindre 24 est solidarisé dans un logement supérieur 5a du premier coulisseau 5 et la tige 25 est reliée de façon articulée au bras pivotant 14 sensiblement au milieu de celui-ci. Preferably, the unlocking member 23 is constituted by a horizontal cylinder, for example of the gas type, the cylinder 24 is secured in an upper housing 5a of the first slider 5 and the rod 25 is connected in an articulated manner the pivot arm 14 substantially in the middle thereof.
[0037] La butée 16 comporte une semelle 26 amoviblement fixée à une face verticale 27 du bâti inférieur 3 par des vis de fixation, non représentées. [0038] La butée 16 comprend en outre une partie 28 faisant saillie de la semelle 26 et qui comporte une face frontale plane et verticale 29 délimitée entre un chanfrein supérieur 30 et un chanfrein inférieur 31. The stop 16 comprises a sole 26 removably attached to a vertical face 27 of the lower frame 3 by fixing screws, not shown. The abutment 16 further comprises a portion 28 projecting from the sole 26 and which has a flat and vertical front face 29 delimited between an upper chamfer 30 and a lower chamfer 31.
[0039] La face plane verticale 29 de la butée 16 a une hauteur prédéterminée h comme cela est symbolisé par la double flèche aux figures 7 et 8. [0040] Le fonctionnement du dispositif de verrouillage et de déverrouillage de l'invention ressort déjà en partie de la description qui précède et va être maintenant expliqué. The vertical plane face 29 of the stop 16 has a predetermined height h as is symbolized by the double arrow in Figures 7 and 8. The operation of the locking and unlocking device of the invention is already apparent in part from the foregoing description and will now be explained.
[0041] La figure 3 représente la situation selon laquelle l'outillage de presse 1 est ouvert, c'est-à-dire que le bâti supérieur 2 et le bloc de commande 9 occupent une position supérieure dégagée d'au dessus du bâti inférieur 3 et à laquelle la pièce à transformer par emboutissage est déposée sur le poinçon, non représenté, de l'outillage de presse 1. [0041] FIG. 3 represents the situation in which the press tooling 1 is open, that is to say that the upper frame 2 and the control block 9 occupy an upper position released from above the lower frame. 3 and to which the workpiece to be converted by stamping is deposited on the punch, not shown, of the press tooling 1.
[0042] A cette position ouverte de l'outillage de presse 1 , le vérin 23 du premier coulisseau 5 est commandé pour que sa tige 25 soit sortie du corps 24 de manière à maintenir le bras de verrouillage 14 à sa position inactive écartée de la trajectoire descendante du bloc de commande 9. In this open position of the press tool 1, the cylinder 23 of the first slider 5 is controlled so that its rod 25 is out of the body 24 so as to maintain the locking arm 14 at its inactive position away from the downward trajectory of the control block 9.
[0043] Ensuite, le bâti supérieur 2 de l'outillage 1 est commandé pour descendre verticalement vers le bâti inférieur 3 jusqu'à ce que la face plane horizontale inférieure 9a du bloc de commande 9 vienne en appui sur la face plane supérieure 1 1 du premier coulisseau 5 et le chanfrein inférieur 22 du bossage 19 du bras 14 vienne en appui sur le chanfrein supérieur 30 de la butée 16 pour permettre au bras 14 d'amorcer son pivotement vers le bloc de commande 9 suivant son axe 17 comme représenté en figure 5. Ainsi débute le déplacement vertical vers le bas du premier coulisseau 5 par le bâti supérieur 2. Then, the upper frame 2 of the tool 1 is controlled to descend vertically to the lower frame 3 until the lower horizontal planar face 9a of the control block 9 bears on the upper planar face 1 1 of the first slide 5 and the lower chamfer 22 of the boss 19 of the arm 14 bears on the upper chamfer 30 of the abutment 16 to allow the arm 14 to initiate its pivoting towards the control block 9 along its axis 17 as shown in FIG. Figure 5. Thus begins the vertical downward movement of the first slider 5 by the upper frame 2.
[0044] La figure 6 représente la situation selon laquelle le bâti supérieur 2 est descendu verticalement avec le coulisseau 5 à sa position de point mort bas sur le bâti inférieur 3 pour effectuer une opération technique sur la pièce de tôlerie et, à cette position, la butée 16 a fait pivoter le bras 14 à sa position de verrouillage du bloc de commande 9 sur le premier coulisseau 5 à laquelle l'extrémité en forme de crochet 15 de ce bras est engagée dans l'encoche conjuguée 12 du bloc de commande 9. A cette position de verrouillage, la face frontale 20 du bossage 19 du bras de verrouillage 14 est en contact intime avec la face frontale verticale 29 de la butée 16 pour maintenir l'extrémité en forme de crochet 15 du bras 14 à sa position engagée dans l'encoche 12 du boîtier de commande 9. Les deux faces frontales 20 du bossage 19 et 29 de la butée 16 sont en contact l'une contre l'autre suivant la même hauteur h. FIG. 6 represents the situation in which the upper frame 2 is lowered vertically with the slider 5 at its bottom dead position on the lower frame 3 to carry out a technical operation on the sheet metal part and, at this position, the stop 16 has pivoted the arm 14 to its locking position of the control block 9 on the first slider 5 to which the hook-shaped end 15 of this arm is engaged in the conjugate notch 12 of the control block 9 In this locking position, the end face 20 of the boss 19 of the locking arm 14 is in intimate contact with the vertical end face 29 of the abutment 16 to maintain the hook-shaped end 15 of the arm 14 in its engaged position. in the notch 12 of the control box 9. The two end faces 20 of the boss 19 and 29 of the stop 16 are in contact with each other at the same height h.
[0045] Une fois l'opération technique effectuée, le bâti supérieur 2 est commandé pour remonter verticalement et, normalement, le premier coulisseau 5 doit remonter sous l'effort du vérin V, mais si cette fonction ne peut être assumée à cause d'une perte de pression dans le vérin V ou de grippage du premier coulisseau 5, le verrouillage par le bras 14 du bloc de commande 9 au premier coulisseau 5 assurera efficacement la remontée du premier coulisseau 5 pendant la remontée du bâti supérieur 2 suivant un effort permettant notamment de vaincre le blocage par grippage de ce coulisseau. Once the technical operation performed, the upper frame 2 is controlled to go up vertically and normally the first slide 5 must go up under the force of the cylinder V, but if this function can not be assumed because of a loss of pressure in the jack V or seizure of the first slider 5, the locking by the arm 14 of the control block 9 at the first slider 5 will effectively raise the first slider 5 during the ascent of the upper frame 2 according to a force including to overcome the blocking jamming of the slider.
[0046] La figure 7 représente la remontée du bâti supérieur 2 à une hauteur déterminée relativement au bâti inférieur 3 à laquelle le vérin 23 va déplacer sa tige 25 pour permettre le pivotement du bras 14 à sa position déverrouillée du bloc de commande 9, amorcée dès que le chanfrein inférieur 22 du bossage 19 de ce bras s'engage sur le chanfrein supérieur 30 de la butée 16 pour occuper ensuite sa position complètement désengagée d'au- dessus de la butée 16 représentée en figure 3. Il est à noter que la hauteur h de la butée 16 détermine la hauteur de remontée du premier coulisseau 5 pendant laquelle le bloc de commande 9 est encore verrouillé au premier coulisseau 5 jusqu'à ce que la face 20 du bossage 19 quitte la face frontale 29 de la butée 16, comme le montre clairement la figure 7. Figure 7 shows the rise of the upper frame 2 at a given height relative to the lower frame 3 to which the cylinder 23 will move its rod 25 to allow pivoting of the arm 14 to its unlocked position of the control block 9, primed as soon as the lower chamfer 22 of the boss 19 of this arm engages on the upper bevel 30 of the abutment 16 to then occupy its completely disengaged position from above the abutment 16 shown in FIG. 3. It should be noted that the height h of the abutment 16 determines the rise height of the first slider 5 during which the control block 9 is still locked to the first slider 5 until the face 20 of the boss 19 leaves the front face 29 of the abutment 16 as clearly shown in Figure 7.
[0047] L'invention ci-dessus décrite présente ainsi les avantages suivants : - elle assure une sécurité optimale puisqu'elle ne nécessite plus d'intervention d'opérateur pour débloquer le coulisseau avec, par conséquent, suppression de tout risque corporel de l'opérateur, The invention described above thus has the following advantages: - it ensures optimal security since it no longer requires operator intervention to unlock the slide with, therefore, eliminating any risk of bodily injury. 'operator,
- du point de vue technique, les coulisseaux ne sont plus bloqués sous pression pouvant aller jusqu'à 1500 daN et elle permet la suppression des risques de détérioration des différents composants des outillages de presse, - From a technical point of view, the slides are no longer locked under pressure up to 1500 daN and it allows the elimination of the risk of deterioration of the various components of the press tools,
- elle permet de réduire considérablement les coûts du fait de la suppression des frais importants de réparation que nécessitaient les outillages de presse antérieurs et liés au montage/démontage des outillages de presse, à la perturbation du flux de productivité, aux heures supplémentaires et/ou à la commande de composants particuliers, - les délais de productivité sont améliorés puisqu'il n'y a plus de perturbation liée au flux d'approvisionnement des pièces au ferrage. - it allows to reduce considerably the costs by the suppression of the important costs of repair which required the previous press tools and related to the assembly / disassembly of the tools of press, the disruption of the productivity flow, overtime and / or to the control of particular components, - the productivity delays are improved since there is no longer any disturbance linked to the supply flow of the pieces to the shoeing.
