Description

La présente invention est relative à des outillages pour des presses-plieuses.The present invention relates to tools for press brakes.

On sait que les outillages des presses destinées à permettre le pliage de tôles métalliques sont généralement constitués d'un poinçon monté de manière amovible sur un tablier supérieur et par une matrice montée de manière amovible sur une table. Le poinçon et la matrice coopèrent l'un avec l'autre en forçant entre eux la tôle à plier, le poinçon présentant une partie en saillie dont le profil correspond sensiblement à celle de l'encoche ménagée en regard dans la matrice. Lors de l'actionnement du tablier supérieur, généralement par des vérins hydrauliques, la tôle engagée entre les deux outils subit une déformation selon un pli plus ou moins prononcé.It is known that the tools of presses intended to allow the bending of metal sheets generally consist of a punch removably mounted on an upper deck and by a die removably mounted on a table. The punch and the matrix cooperate with each other by forcing between them the sheet to bend, the punch having a projecting part whose profile corresponds substantially to that of the notch made opposite in the matrix. When the upper deck is actuated, generally by hydraulic cylinders, the sheet engaged between the two tools undergoes deformation in a more or less pronounced fold.

La fixation des poinçons et des matrices s'effectue par différents moyens connus et propres à chaque constructeur de presses-plieuses. De tels systèmes de fixation sont par exemple décrit dans le brevet français FR2122977. Ils présentent l'inconvénient d'imposer un outillage spécifique à la presse-plieuse, et d'interdire l'utilisation d'outillages d'origine différente.The punches and dies are fixed by different means known and specific to each manufacturer of press brakes. Such fastening systems are for example described in French patent FR2122977. They have the drawback of imposing specific tools on the press brake, and of prohibiting the use of tools of different origin.

On connaît également dans l'état de la technique des adaptateurs permettant d'utiliser sur une presse-plieuse des outillages de différentes origines. Un tel adaptateur est décrit dans le brevet EP494714. Cet adaptateur met en oeuvre des mécanismes pour le maintien de l'outillage relativement complexes et donc peu fiables.Also known in the state of the art are adapters making it possible to use on a press brake tools of different origins. Such an adapter is described in patent EP494714. This adapter implements mechanisms for maintaining the tools that are relatively complex and therefore unreliable.

L'objet de la présente invention est de remédier à cet inconvénient en proposant un adaptateur et des outillages associés faciles à mettre en place et offrant une grande résistance et fiabilité, et permettant l'adaptation d'outillages sur des presses de types différents.The object of the present invention is to remedy this drawback by proposing an adapter and associated tools which are easy to install and which offer great resistance and reliability, and allowing the adaptation of tools on presses of different types.

A cet effet, l'invention concerne plus particulièrement un adaptateur pour le montage d'outillages sur une presse-plieuse, constitué par un corps en forme de barreau présentant un premier talon spécifique à un type de presse-plieuse donné et apte à coopérer avec la table ou le tablier supérieur de ladite presse-plieuse, et un moyen de fixation de l'outillage, caractérisé en ce que le moyen de fixation de l'outillage est constitué par un talon central spécifique à l'outillage.To this end, the invention relates more particularly to an adapter for mounting tools on a press brake, consisting of a rod-shaped body having a first heel specific to a given type of press brake and capable of cooperating with the table or the upper deck of said press brake, and a tool fixing means, characterized in that the tool fixing means is constituted by a central heel specific to the tool.

Ce talon permet de positionner facilement la gorge complémentaire d'un poinçon ou d'une matrice. Il garantit une bonne répartition des efforts.This heel makes it easy to position the complementary groove of a punch or a die. It guarantees a good distribution of efforts.

De préférence, le talon central spécifique à l'outillage est centré par rapport à un plan longitudinal contenant l'axe de la poussée de pliage.Preferably, the central heel specific to the tool is centered relative to a longitudinal plane containing the axis of the folding thrust.

Avantageusement, l'adaptateur selon l'invention présente des surfaces d'appui longitudinales de part et d'autre du talon central spécifique à l'outillage.Advantageously, the adapter according to the invention has longitudinal bearing surfaces on either side of the central heel specific to the tool.

Selon un mode de réalisation particulier, le talon central spécifique à l'outillage comporte au moins un élément saillant au repos, propre à coopérer avec une gorge prévue sur l'outillage.According to a particular embodiment, the central heel specific to the tool comprises at least one protruding element at rest, adapted to cooperate with a groove provided on the tool.

Selon une première variante, le talon central spécifique à l'outillage comporte un organe de verrouillage longitudinal rotatif entre une position de démontage dans laquelle il s'efface à l'intérieur du talon, et une position de blocage dans laquelle il forme une saillie propre à coopérer avec une gorge prévue sur l'outillage.According to a first variant, the central heel specific to the tool comprises a rotary longitudinal locking member between a disassembly position in which it disappears inside the heel, and a locking position in which it forms its own projection to cooperate with a groove provided on the tool.

Selon une deuxième variante, l'organe de verrouillage est constitué par une tige cylindrique présentant un méplat longitudinal.According to a second variant, the locking member consists of a cylindrical rod having a longitudinal flat.

Selon une troisième variante, le talon de l'adaptateur présente une pluralité d'organes saillants au repos et escamotables pour permettre le mise en place de l'outillage, l'adaptateur comportant en outre un moyen mobile pour bloquer l'ensemble des organes saillants en position saillante pour le blocage de la totalité des outillages après leur mise en place sur l'adaptateur. Ce moyen de blocage peut être constitué par une tige avec un méplat agissant sur l'extrémité intérieure des organes saillants, par l'intermédiaire d'une pièce de liaison compressible élastiquement, par exemple un ressort. Cette variante permet de monter plusieurs poinçons ou matrices élémentaires sur un adaptateur, ceux-ci étant maintenus en position provisoirement par la coopération entre les organes saillants au repos et la nervure de la gorge, et étant ensuite verrouillés en bloc lors de l'actionnement de la tige de blocage en position de verrouillage dans laquelle elle empêche l'escamotage des organes saillants.According to a third variant, the heel of the adapter has a plurality of protruding members at rest and retractable to allow the installation of the tool, the adapter further comprising a movable means for blocking all of the protruding members in the protruding position for blocking all the tools after their installation on the adapter. This locking means can be constituted by a rod with a flat acting on the inner end of the projecting members, by means of an elastically compressible connecting piece, for example a spring. This variant makes it possible to mount several punches or elementary dies on an adapter, these being held in position provisionally by the cooperation between the projecting members at rest and the rib of the groove, and then being locked in block during actuation of the locking rod in the locking position in which it prevents the retraction of the projecting members.

L'invention concerne également un poinçon et une matrice pour coopérer avec un adaptateur présentant à leur partie de liaison une gorge longitudinale dont la section est complémentaire de la section du talon de l'adaptateur.The invention also relates to a punch and a die for cooperating with an adapter having at their connecting part a longitudinal groove whose section is complementary to the section of the heel of the adapter.

Selon un mode de réalisation préféré, la gorge longitudinale présente une nervure en creux latérale pour recevoir l'élément de blocage saillant du talon de l'adaptateur.According to a preferred embodiment, the longitudinal groove has a lateral hollow rib for receiving the protruding blocking element of the heel of the adapter.

Selon une variante avantageuse, le poinçon et la matrice présentent une cavité latérale pour l'introduction d'une broche de manutention. Cette broche permet de manipuler l'outillage sans risque de blessure.According to an advantageous variant, the punch and the die have a lateral cavity for the introduction of a handling spindle. This pin allows you to handle the tools without risk of injury.

Selon une autre variante avantageuse, ils présentent un alésage longitudinal de section hexagonale pour le raccordement de plusieurs outils juxtaposés.According to another advantageous variant, they have a longitudinal bore of hexagonal section for the connection of several juxtaposed tools.

L'invention sera décrite dans ce qui suit selon un exemple non limitatif de réalisation, faisant référence aux dessins annexés où :

  • la figure 1 représente une vue en coupe de l'outillage ;
  • la figure 2 représente une vue agrandie d'une variante de talon d'adaptateur ;
  • la figure 3 représente une vue en coupe d'une variante de matrice ,
  • la figure 4 représente une vue en coupe d'une deuxième variante de matrice ,
  • la figure 5 représente une vue partielle de la deuxième variante en position de démontage.
The invention will be described in the following according to a nonlimiting exemplary embodiment, referring to the appended drawings where:
  • Figure 1 shows a sectional view of the tool;
  • FIG. 2 represents an enlarged view of a variant adapter heel;
  • FIG. 3 represents a sectional view of a variant of the matrix,
  • FIG. 4 represents a sectional view of a second variant of the matrix,
  • FIG. 5 represents a partial view of the second variant in the disassembly position.

La figure 1 représente une vue en coupe médiane de l'outillage constitué par un adaptateur supérieur (1), un poinçon (2), une matrice (3) et un adaptateur inférieur.FIG. 1 represents a view in median section of the tool consisting of an upper adapter (1), a punch (2), a die (3) and a lower adapter.

L'adaptateur supérieur (1) présente à sa partie supérieure (5) un talon dont la section est déterminée pour permettre le montage sur le tablier supérieur d'une presse-plieuse d'un type déterminé. La face opposée présente un talon (6) de section rectangulaire centré par rapport à l'axe de poussée de pliage (7). De part et d'autre de ce talon (6), l'adaptateur présente des épaulements (8, 9) dont la surface s'étend dans le plan perpendiculaire à l'axe de poussée (7) . Le talon (6) présente un alésage longitudinal (10) de forme cylindrique s'ouvrant sur la face latérale (12) du talon par une fenêtre rectangulaire d'une hauteur inférieure à la section de l'alésage (10). A l'intérieur de cet alésage (10) est placée une tige (11) de forme cylindrique présentant un méplat (13) de forme rectangulaire.The upper adapter (1) has at its upper part (5) a heel whose section is determined to allow mounting on the upper deck of a press brake of a specific type. The opposite face has a heel (6) of rectangular section centered with respect to the folding thrust axis (7). On either side of this heel (6), the adapter has shoulders (8, 9) whose surface extends in the plane perpendicular to the thrust axis (7). The heel (6) has a longitudinal bore (10) of cylindrical shape opening on the lateral face (12) of the heel by a rectangular window with a height less than the cross section of the bore (10). Inside this bore (10) is placed a rod (11) of cylindrical shape having a flat (13) of rectangular shape.

Le poinçon présente à sa partie opposée à la lèvre (14) une gorge médiane (15) présentant sur l'une des faces latérales une nervure (16).The punch has at its part opposite the lip (14) a central groove (15) having on one of the lateral faces a rib (16).

La position de cette nervure (16) correspond à la position de la fenêtre s'ouvrant sur l'alésage (10). Lorsque le méplat (13) est orienté vers la fenêtre, il est dans le plan de la face latérale du talon (6) et le poinçon peut être déplacé suivant la direction de l'axe (7), afin de le retirer ou de le mettre en place. Lorsque l'on fait tourner de 180° la tige (11), celle-ci fait saillie à travers la fenêtre et la partie saillante vient se loger dans la nervure (16) de la gorge (15) du poinçon (2).The position of this rib (16) corresponds to the position of the window opening on the bore (10). When the flat (13) is oriented towards the window, it is in the plane of the lateral face of the heel (6) and the punch can be moved in the direction of the axis (7), in order to remove it or to implement. When the rod (11) is rotated by 180 °, it projects through the window and the projecting part is housed in the rib (16) of the groove (15) of the punch (2).

Lorsque le poinçon (2) est en position dans l'adaptateur (1), les bords supérieurs viennent s'appuyer sur les épaulements (8, 9) de l'adaptateur (1) et le bord inférieur (17) du talon vient s'appuyer sur le fond plat de la gorge (15). Le poinçon (2) présente un alésage (21) longitudinal à section polygonale, permettant le passage d'une tige de liaison destinée à l'accouplement de plusieurs outils. Cet alésage (21) permet également d'introduire une broche de manutention pour la manipulation du poinçon.When the punch (2) is in position in the adapter (1), the upper edges come to rest on the shoulders (8, 9) of the adapter (1) and the lower edge (17) of the heel comes '' press on the flat bottom of the groove (15). The punch (2) has a longitudinal bore (21) with a polygonal section, allowing the passage of a connecting rod intended for the coupling of several tools. This bore (21) also makes it possible to introduce a handling spindle for handling the punch.

L'adaptateur inférieur (4) présente un talon (19) identique au talon (6) de l'adaptateur supérieur (1). Sa partie inférieure est adaptée pour permettre la fixation sur la table d'une presse-plieuse d'un type déterminé. Le fait que les talons (6, 19) des deux adaptateurs (1, 4) soient identiques permet de monter sur chacun indifféremment un poinçon ou une matrice.The lower adapter (4) has a heel (19) identical to the heel (6) of the upper adapter (1). Its lower part is adapted to allow the fixing on the table of a press brake of a determined type. The fact that the heels (6, 19) of the two adapters (1, 4) are identical makes it possible to mount on each indifferently a punch or a die.

La matrice (3) présente une gorge (20) identique à la gorge (15) du poinçon (2), et un alésage (22) identique à celui (21) du poinçon (2). Les alésages (21, 22) sont de préférence centrés sur l'axe de poussée (7).The die (3) has a groove (20) identical to the groove (15) of the punch (2), and a bore (22) identical to that (21) of the punch (2). The bores (21, 22) are preferably centered on the thrust axis (7).

La figure 2 représente une vue agrandie du talon de l'adaptateur conforme à une variante de réalisation. La paroi latérale (30) du talon présente une fenêtre longitudinale (31) ou circulaire. Cette fenêtre communique avec un alésage cylindrique (32) à l'intérieur duquel est logée une tige cylindrique (35) présentant un méplat (36). La tige coopère avec un téton (34) par l'intermédiaire d'un élément compressible élastiquement (33), par exemple un ressort. Le téton (34) est en érection au repos et fait saillie par rapport à la face latérale (30). Lors de la mise en place du poinçon ou de la matrice sur l'adaptateur, le téton (34) s'efface, puis ressort de manière à ce que son extrémité vienne se loger dans la nervure latérale de la gorge. En tournant la tige (35) d'un demi-tour, on provoque le verrouillage du téton en position d'érection.Figure 2 shows an enlarged view of the heel of the adapter according to an alternative embodiment. The side wall (30) of the heel has a longitudinal (31) or circular window. This window communicates with a cylindrical bore (32) inside which is housed a cylindrical rod (35) having a flat (36). The rod cooperates with a stud (34) via an elastically compressible element (33), for example a spring. The nipple (34) is erect at rest and protrudes from the lateral face (30). When placing the punch or the die on the adapter, the stud (34) disappears, then comes out so that its end comes to lodge in the lateral rib of the groove. By turning the rod (35) a half-turn, it causes the locking of the stud in the erection position.

La figure 3 représente une vue en coupe d'une variante de matrice multi-V. L'adaptateur coopère avec la matrice par l'intermédiaire d'une cale (38) de part ou d'autre en fonction de la fente (39 ou 40) utilisée.Figure 3 shows a sectional view of a variant of multi-V matrix. The adapter cooperates with the matrix via a wedge (38) on either side depending on the slot (39 or 40) used.

La figure 4 représente une vue en coupe d'une deuxième variante de matrice. L'adaptateur supérieur (50) est formé par un barreau longitudinal présentant à sa surface supérieure (51) deux rangées de trous (52, 53) pour la fixation sur la presse. Le barreau longitudinal présente une partie supérieure (54) de forme sensiblement parallélépipédique prolongée à sa surface inférieure par un talon longitudinal (55) dont la face intérieure (56) s'étend sensiblement dans le plan médian (7). Cette face intérieure (56) présente une rainure semi-cylindrique (57) dans laquelle vient se loger un tube expansible (58). L'adaptateur comporte par ailleurs une pluralité d'organes de verrouillage basculant (59) présentant sur l'une des faces (60) une rainure (61) positionnée en regard de la rainure semi-cylindrique (57) du talon (55), et sur sa surface extérieure (62) une protubérance (63) complémentaire de la nervure (16) du poinçon (40). Les organe de verrouillages basculants (59) sont montés sur des pivots (65).Figure 4 shows a sectional view of a second variant of the matrix. The upper adapter (50) is formed by a longitudinal bar having at its upper surface (51) two rows of holes (52, 53) for fixing to the press. The longitudinal bar has an upper part (54) of substantially parallelepiped shape extended at its lower surface by a longitudinal heel (55) whose inner face (56) extends substantially in the median plane (7). This inner face (56) has a semi-cylindrical groove (57) in which is housed an expandable tube (58). The adapter also comprises a plurality of tilting locking members (59) having on one of the faces (60) a groove (61) positioned opposite the semi-cylindrical groove (57) of the heel (55), and on its outer surface (62) a protuberance (63) complementary to the rib (16) of the punch (40). The tilting locking members (59) are mounted on pivots (65).

Le tube expansible (58) est relié à une source d'air ou de fluide comprimé. Lorsqu'il est mis en charge, il tend écarter l'organe de verrouillage basculant (59) du talon (55), et la protubérance (63) vient se loger dans la rainure (16) du poinçon (40). Celui-ci est alors bloqué et parfaitement solidaire de l'adaptateur et de la presse.The expandable tube (58) is connected to a source of compressed air or fluid. When loaded, it tends to move the tilting locking member (59) away from the heel (55), and the protuberance (63) is housed in the groove (16) of the punch (40). This is then blocked and perfectly secured to the adapter and the press.

De la même manière, la matrice est fixé sur la table de la presse par un adaptateur comprenant des organe de verrouillages basculant repoussés par un tube expansible. Si le tube expansible (58) est coupé de la source d'air ou de fluide comprimé, il devient déformable, comme représenté en figure 5 et peut s'écraser pour permettre le rapprochement de l'organe de verrouillage basculant (59) et du talon (55). Le poinçon peut alors être dégagé par un traction verticale.Likewise, the die is fixed to the press table by an adapter comprising tilting locking members pushed back by an expandable tube. If the expandable tube (58) is cut from the source of compressed air or fluid, it becomes deformable, as shown in Figure 5 and can be crushed to allow the tilting locking member (59) and the heel (55). The punch can then be released by a vertical pull.

L'invention est décrite dans ce qui précède à titre d'exemple non limitatif.The invention is described in the foregoing by way of nonlimiting example.
