Description

La présente invention a pour objet une machine destinée à la formation de panneaux de tôle et, plus particulièrement, à la réalisation des pliages nécessaires aux tôles d'application en utilisant des moyens qui rendent efficacement avantageux le travail de cette fonction.The present invention relates to a machine intended for the formation of sheet metal panels and, more particularly, to carry out the necessary folds to the application plates using means which effectively make the work of this function.

On connaít déjà des machines qui réalisent automatiquement le pliage de tôles, selon des angles prédéterminés, lesdites machines comprenant un poinçon et une matrice, entre lesquels se réalise le formage des tôles par pliage, cette opération étant menée à bien par des pliages progressifs, pour compenser la capacité de récupération des tôles pliées qui varie en fonction de divers facteurs, tels que la nature du matériau, la grosseur, etc..We already know machines that realize automatically bending sheets, at angles predetermined, said machines comprising a punch and a matrix, between which the forming of sheets by folding, this operation being carried out by progressive folding, to compensate for the capacity of recovery of folded sheets which varies depending on various factors, such as the nature of the material, the size, etc.

La précision du pliage requiert, en outre, un contrôle exact de l'angle obtenu et, à cet effet, on utilise des systèmes de mesure associés au procédé de pliage, consistant en un instrument de mesure par laser, en dispositifs complexes intégrés au poinçon de pliage ou en appareils portables indépendants, les systèmes en question s'avérant compliqués et coûteux.Folding precision also requires exact control of the angle obtained and, for this purpose, uses measurement systems associated with the folding, consisting of a laser measuring instrument, in complex devices integrated into the folding punch or in independent portable devices, the systems in question proving complicated and expensive.

Pour mesurer l'angle de pliage, il existe plusieurs solutions et, notamment, celle proposée dans le Brevet US 4 564 765 qui utilise un mesureur laser, celle du Brevet US 4 489 586 qui utilise un dispositif incorporé au poinçon de pliage ou celle du Brevet US 3 146 819 qui utilise un butoir palpeur d'appui de la tôle pliée.To measure the folding angle, there are several solutions and, in particular, that proposed in the US Patent 4,564,765 which uses a laser meter, that of the Patent US 4,489,586 which uses a device incorporated in the folding punch or that of US Patent 3,146,819 which uses a feeler stop to support the folded sheet.

La présente invention a pour objet une machine qui inclut des moyens de réalisation du pliage et un dispositif de mesure de l'angle de la tôle pliée, différents dans leur conception des systèmes connus et offrant certains avantages pour la fonction pratique du pliage des tôles d'application. The subject of the present invention is a machine which includes means for folding and a device for measuring the angle of the folded sheet, different in their design of known systems and offering certain advantages for the practical function of the folding of the application sheets.

La machine faisant l'objet de la présente invention comprend un mécanisme de pliage composé d'un porte-lames mobile situé en face d'un dispositif de maintien et immobilisation des tôles à plier, le dispositif d'immobilisation comprenant une partie inférieure fixe ou contre-lame et un serre-tôles supérieur actionné verticalement à l'aide d'un vérin poussoir, tandis que le porte-lames est muni d'un palpeur disposé sur un vérin de déplacement qui le conduit vers le dispositif d'immobilisation des tôles.The machine which is the subject of the present invention includes a folding mechanism consisting of a blade holder mobile located in front of a holding device and immobilization of the sheets to be folded, the device immobilizer comprising a fixed lower part or counter blade and an actuated upper sheet clamp vertically using a push cylinder, while the blade holder is fitted with a probe arranged on a cylinder displacement which leads it towards the device sheet immobilization.

Le porte-lames est incorporé à un dispositif de translation qui assure son déplacement vers le dispositif d'immobilisation des tôles et à un dispositif articulé de basculement qui permet de faire varier verticalement sa position par rapport au dispositif d'immobilisation des tôles, les deux mouvements étant assurés par les deux vérins d'entraínement.The blade holder is incorporated in a device for translation which ensures its movement towards the device sheet immobilization and an articulated device tilting which allows to vertically vary its position relative to the immobilizer sheets, the two movements being provided by the two drive cylinders.

Le serre-tôles du dispositif d'immobilisation des tôles est disposé sur un chariot entraíné par le vérin poussoir, le serre-flans en question se composant d'un ensemble formé de deux blocs d'extrémité et d'un bloc central qui déterminent une forme longitudinale continue, le bloc central pouvant être remplacé pour moduler la dimension longitudinale de l'ensemble en fonction de la largeur des tôles d'application.The sheet clamps of the device for immobilizing sheets is arranged on a carriage driven by the cylinder pusher, the blank holder in question consisting of a assembly formed by two end blocks and a block central which determine a continuous longitudinal shape, the central block can be replaced to modulate the longitudinal dimension of the assembly as a function of the width of the application sheets.

Le porte-lames inclut un chariot capable de transporter automatiquement le bloc central du serre-flans de la position de montage jusqu'à un magasin contenant plusieurs blocs de différentes longueurs, pour permettre le remplacement sélectif du bloc en question dans l'adaptation longitudinale du serre-flans, le chariot de remplacement étant entraíné par un vérin indépendant ou associé à celui du palpeur également incorporé au porte-lames. The blade holder includes a cart capable of automatically transport the central block of the blank holder from the mounting position to a magazine containing several blocks of different lengths, to allow selective replacement of the block in question in the longitudinal adaptation of the blank holder, the carriage replacement being driven by an independent cylinder or associated with that of the probe also incorporated in the blade holder.

On obtient ainsi un groupe fonctionnel qui permet de réaliser rapidement et avec précision le pliage de tôles selon des angles prédéterminés, en contrôlant à l'aide d'un mesurage automatique l'angle du pliage aux fins de déterminer les corrections nécessaires à l'opération.A functional group is thus obtained which makes it possible to quickly and precisely bend sheets at predetermined angles, controlling with automatic measurement of the folding angle for determine the corrections necessary for the operation.

En outre, l'ensemble fonctionnel peut s'adapter à des tôles de différentes largeurs, grâce au changement sélectif automatique de la longueur du serre-flans d'immobilisation, ce qui permet d'obtenir une grande vitesse dans l'agencement opérationnel de fonctionnement par rapport aux tôles d'application.In addition, the functional assembly can be adapted to sheets of different widths, thanks to the change automatic selection of the length of the blank holder of immobilization, which makes it possible to obtain a large speed in the operational operating arrangement compared to the application sheets.

Par conséquent, la machine faisant l'objet de la présente invention possède réellement des caractéristiques très avantageuses, en acquérant une vie propre et un caractère de référence pour la fonction à laquelle elle est destinée.Therefore, the machine subject to present invention actually has features very advantageous, by acquiring a clean life and a reference character for the function to which it is intended.

La figure 1 montre une vue latérale sectionnée de la panneauteuse préconisée.Figure 1 shows a sectioned side view of the panel maker recommended.

La figure 2 est une vue sectionnée de la machine, en plan supérieur.FIG. 2 is a sectioned view of the machine, in upper shot.

Les figures 3A à 3E montrent une séquence des positions successives de l'opération de pliage d'une tôle et le contrôle de l'angle de pliage.Figures 3A to 3E show a sequence of successive positions of the bending operation of a sheet and control of the folding angle.

L'invention a pour objet une panneauteuse destinée à réaliser automatiquement le pliage de tôles (1), selon les plis nécessaires à la formation de panneaux de portes, de cloisonnages ou applications similaires.The subject of the invention is a paneling machine intended for automatically bend sheets (1), according to the folds necessary for the formation of door panels, partitions or similar applications.

La machine dispose d'un mécanisme de pliage qui comprend un porte-lames (2) disposé, en montage mobile, face à un dispositif d'immobilisation des tôles (1) à plier.The machine has a folding mechanism which comprises a blade holder (2) arranged, in mobile mounting, facing a sheet immobilization device (1) at to fold.

Le dispositif d'immobilisation comprend une partie inférieure (3) ou contre-lame fixée sur le bâti structurel (4) de la machine et un serre-flans supérieur (5) susceptible d'être entraíné verticalement en appui contre la partie inférieure (3) susmentionnée afin d'immobiliser entre l'une et l'autre partie les tôles (1) d'application pour pouvoir réaliser les opérations de pliage.The immobilizer comprises a part lower (3) or counter blade fixed on the structural frame (4) of the machine and an upper hold-down (5) likely to be driven vertically against the lower part (3) mentioned above in order to immobilize between one and the other part the application sheets (1) to be able to perform the folding operations.

Le porte-lames (2) est disposé en articulation de basculement vertical sur des chariots porteurs (6) montés sur des glissières qui les conduisent vers le dispositif d'immobilisation des tôles (1).The blade holder (2) is arranged in articulation of vertical tilting on carrier trolleys (6) mounted on slides that lead them to the device sheet immobilization (1).

Les chariots (6) sont unis aux vérins (7) respectifs qui permettent de les faire avancer et reculer tandis que le porte-lames (2) est uni à un ou plusieurs vérins (8) qui assurent le basculement vertical du porte-lames (2) par rapport à l'articulation prévue sur les chariots porteurs (6).The carriages (6) are joined to the respective cylinders (7) which allow them to move forward and backward while the blade holder (2) is joined to one or more cylinders (8) which ensure the vertical tilting of the blade holder (2) in relation to the articulation provided on the carriages carriers (6).

Le porte-lames (2) est équipé d'un palpeur (9) disposé sur un vérin (10) qui le conduit jusqu'à la partie frontale où se trouve le dispositif d'immobilisation des tôles (1).The blade holder (2) is equipped with a probe (9) arranged on a jack (10) which leads it to the part front where the immobilizer of the sheets (1).

Ainsi, la tôle (1) à plier est retenue à l'aide du dispositif d'immobilisation entre le serre-flans (5) et la partie fixe (3), tel qu'illustré sur la figure 3A, de telle sorte que lorsque la tôle se retrouve dans cette position, le déplacement du porte-lames (2) entraíné par les vérins (7 et 8) provoque le pliage de l'extrémité de la tôle (1) immobilisée, tel que représenté sur la figure 3B.Thus, the sheet (1) to be folded is retained using the immobilization device between the blank holder (5) and the fixed part (3), as illustrated in FIG. 3A, of so that when the sheet ends up in this position, the movement of the blade holder (2) driven by the jacks (7 and 8) cause the end of the the sheet (1) immobilized, as shown in the figure 3B.

Le porte-lames est entraíné automatiquement par les vérins (7 et 8)en fonction de l'angle de pliage programmé dans le contrôle de la machine, le pliage de la tôle s'effectuant lors d'une première opération selon l'angle programmé, sans dépasser cet angle, après quoi le porte-lames (2) retourne à la position de départ, tel qu'illustré à la figure 3C.The blade holder is automatically driven by the cylinders (7 and 8) depending on the programmed folding angle in the control of the machine, the bending of the sheet performed during a first operation according to the angle programmed, without exceeding this angle, after which the blade holder (2) returns to the starting position, as as illustrated in Figure 3C.

Le vérin(10) entraíne ensuite le palpeur (9) et le conduit jusqu'à la zone de pliage de la tôle (1), tel qu'illustré à la figure 3D; puis, par le basculement nécessaire du porte-lames (2), le palpeur (9) est mis au contact de la zone extrême de la partie pliée de la tôle (1), tel qu'illustré à la figure 3E.The cylinder (10) then drives the probe (9) and the leads to the bending zone of the sheet (1), as as illustrated in Figure 3D; then, by tilting blade holder (2) required, the probe (9) is set to contact of the extreme zone of the folded part of the sheet (1), as shown in Figure 3E.

On réalise ainsi deux mesures sur la partie pliée de la tôle (1), qui permettent d'obtenir avec une précision absolue le résultat de l'angle de pliage, afin que grâce au traitement de cette valeur, et par comparaison avec l'angle réel programmé, le contrôle de la machine adopte la correction nécessaire pour compenser, par une autre opération de pliage, tout défaut éventuel jusqu'à ce que l'on obtienne l'angle exact. Two measurements are thus made on the folded part of the sheet (1), which allow to obtain with precision absolute the result of the folding angle, so that thanks when processing this value, and by comparison with the actual programmed angle, the machine control adopts the correction necessary to compensate, by another folding operation, any defect until we get the exact angle.

Le serre-flans (5) est disposé sur un chariot (11) articulé sur le bâti structurel (4) de la machine, le chariot (11) en question étant entraíné en basculement par le vérin(12), ce même vérin exerce une pression contre les tôles (1) pour les immobiliser en amenant le serre-flans (5) contre la partie inférieure fixe (3).The blank holder (5) is arranged on a carriage (11) articulated on the structural frame (4) of the machine, the carriage (11) in question being driven in tilting by the jack (12), this same jack exerts pressure against the sheets (1) to immobilize them by bringing the blank holder (5) against the fixed lower part (3).

Le serre-flans (5) se compose de deux blocs d'extrémité et d'un bloc central qui déterminent la longueur du corps du serre-flans (5), le bloc central pouvant être remplacé par des blocs de différentes longueurs, ce qui permet d'adapter la longueur de l'ensemble du serre-flans (5) en fonction de la largeur des tôles (1) d'application pour que l'opération de la machine soit aussi précise que possible dans chaque cas.The blank holder (5) consists of two blocks end and a central block which determine the length of the body of the blank holder (5), the central block can be replaced by blocks of different lengths, which allows you to adjust the length of the whole blank holder (5) depending on the width application sheets (1) so that the operation of the machine is as precise as possible in each case.

A cet effet, le porte-lames (2) est équipé d'un chariot (13) qui permet de remplacer automatiquement le bloc central du serre-flans (5) en fonction de la largeur des tôles (1) à plier avec la machine dans chaque cas, de telle sorte que le chariot (13) se déplace et saisisse au passage le bloc central du serre-flans (5) pour le conduire à un magasin (non représenté) contenant plusieurs blocs semblables, de différentes longueurs, où le chariot (13) en question prend le bloc de longueur appropriée, l'emmène ensuite jusqu'au serre-flans (5) et le dépose au centre de celui-ci.For this purpose, the blade holder (2) is equipped with a carriage (13) which automatically replaces the central block of the blank holder (5) depending on the width sheets (1) to be folded with the machine in each case, so that the carriage (13) moves and grips pass the central block of the blank holder (5) for the lead to a store (not shown) containing several similar blocks, of different lengths, where the carriage (13) in question takes the appropriate length block, then take it to the blank holder (5) and place it in the center of it.

Le chariot (13) est entraíné par un vérin (14) commandé par le contrôle de la machine, ledit vérin (14) pouvant être un vérin indépendant, servant uniquement à déplacer le chariot (13); mais on a prévu également la possibilité d'utiliser pour cette fonction le vérin (10) du palpeur (9), auquel cas le chariot (13) serait associé audit vérin (10) par rapport au contrôle correspondant pour réaliser cette fonction de changement du bloc central du serre-flans (5). The carriage (13) is driven by a jack (14) controlled by the machine control, said cylinder (14) can be an independent cylinder, used only for move the carriage (13); but we also planned the possibility of using the jack (10) for this function of the probe (9), in which case the carriage (13) would be associated said cylinder (10) relative to the corresponding control to perform this central block change function blank holder (5).

Bien entendu, la description ci-dessus n'a été donnée qu'à titre d'exemple non limitatif et diverses modifications pourront y être apportées par l'homme de l'art sans pour cela sortir du domaine de l'invention.Of course, the above description has not been given as a nonlimiting and diverse example modifications can be made by the man of art without departing from the scope of the invention.
