Furthermore, they do not allow sufficient flexibility of the settings.

La présente invention se rapporte à une machine permettant de réaliser des cambrages sans nécessiter de pivotement du fil. Cette machine peu onéreuse permet de réduire les délais d'industrialisation. Elle facilite la mise au point par le nombre limité d'outils de forme. Elle permet de suivre facilement les modifications éventuelles des pièces à façonner. Du fait que le fil est toujours maintenu pendant le façonnage, la qualité des pièces obtenues est bonne. La machine permet de réaliser des cambrages rapprochés et de réaliser facilement les réglages sans déplacer les actionneurs.The present invention relates to a machine for making bends without requiring pivoting of the wire. This inexpensive machine reduces industrialization times. It facilitates the development by the limited number of shaping tools. It allows easy monitoring of any changes to the workpieces. Because the wire is always held during the shaping, the quality of the parts obtained is good. The machine allows close bends and easy adjustments without moving the actuators.

La machine selon l'invention est caractérisée par le fait qu'elle comporte des unités de cambrage équipées chacune d'une tête rotative de cambrage du fil tournant autour d'un axe orthogonal à l'axe d'alimentation du fil.The machine according to the invention is characterized in that it comprises bending units each equipped with a rotary head for bending the wire rotating around an axis orthogonal to the axis of supply of the wire.

Selon une caractéristique, l'unité de cambrage comporte une broche cylindrique rotative munie de deux poins et assurant, par rotation, le pliage du fil engagé entre les pions et des moyens pour déplacer ladite broche en translation de manière à assurer le dégagment du fil après pliage de celui-ci.According to one characteristic, the cambering unit comprises a rotary cylindrical spindle provided with two pins and ensuring, by rotation, the folding of the wire engaged between the pins and means for moving said spindle in translation so as to ensure the disengagement of the wire after folding of it.

Selon une autre caractéristique, l'unité de cambrage comporte un moteur d'entraînement en rotation de la broche qui est monté sur les parties fixes et est relié à la broche par l'intermédiaire d'une liaison homocinétique.According to another characteristic, the cambering unit comprises a motor for rotating the spindle which is mounted on the fixed parts and is connected to the spindle by means of a constant velocity connection.

Selon une caractéristique, l'unité de cambrage est montée sur des moyens de support permettant son orientation autour de l'axe d'ali­mentation du fil.According to one characteristic, the bending unit is mounted on support means allowing its orientation around the wire supply axis.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation donné à titre d'exemple et représenté par les dessins annexés sur lesquels :

  • - la figure 1 est une vue générale de la machine,
  • - la figure 2 est une coupe selon II - II de la figure 1,
  • - la figure 3 est une coupe selon III - III de la figure 1,
The invention will now be described in more detail with reference to an embodiment given by way of example and represented by the appended drawings in which:
  • FIG. 1 is a general view of the machine,
  • FIG. 2 is a section on II - II of FIG. 1,
  • FIG. 3 is a section on III - III of FIG. 1,

En se référant aux dessins, la machine comporte un châssis plan 1 (table ou marbre) porté par un bati non représenté. Ce châssis peut être incliné.Referring to the drawings, the machine comprises a flat frame 1 (table or marble) carried by a frame, not shown. This chassis can be tilted.

Les fils à cambrer 5 alimentent la machine selon un axe d'alimentation repéré 51. L'alimentation peut être manuelle. Dans ce cas, l'opérateur positionne un flan de fil redressé et coupé. L'alimentation peut être assurée par un dispositif automatique. Un premier type de dispositif d'alimentation automatique peut être constitué par un chargeur contenant les flans prédécoupés. Un autre type de dispositif automatique peut assurer le redressage, le défilement et la coupe d'un fil à partir d'une bobine.The wires to be bent 5 supply the machine along a supply axis marked 51. The supply can be manual. In this case, the operator positions a straight and cut yarn blank. Power can be supplied by an automatic device. A first type of automatic feeding device can be constituted by a charger containing the precut blanks. Another type of automatic device can ensure the straightening, running and cutting of a wire from a spool.

Le châssis porte une unité de cambrage linéaire 2, une première unité de cambrage rotative 3 et une seconde unité de cambrage rotative 4.The chassis carries a linear camber unit 2, a first rotary camber unit 3 and a second rotary camber unit 4.

L'unité de cambrage linéaire 2 se compose d'un support 21 muni de glissières 22 servant à guider un coulisseau mobile 23 selon un axe 24. Le coulisseau porte à l'extrémité avant un outil de formage 25 présentant un profil galbé adapté au cambrage désiré.The linear bending unit 2 consists of a support 21 provided with slides 22 used to guide a movable slide 23 along an axis 24. The slide carries at the front end a forming tool 25 having a curved profile suitable for bending longed for.

Ce coulisseau mobile coopère avec une enclume fixe 26 équipée avec un outil de formage 27 présentant un profil galbé conjugué avec le profil du coulisseau.This movable slide cooperates with a fixed anvil 26 equipped with a forming tool 27 having a curved profile conjugated with the profile of the slide.

Le coulisseau mobile 23 est animé d'un mouvement rectiligne alternatif par un actionneur linéaire 28, du type vérin, fixé sur le support 21. L'ensemble de l'unité 2 peut être déplacé horizontalement sur le châssis 1. Généralement l'axe 24 est perpendiculaire à l'axe 51. L'unité peut être inclinée sans le plan du châssis 1 par rapport à l'axe d'alimentation 51 du fil.The movable slide 23 is driven in an alternating rectilinear movement by a linear actuator 28, of the jack type, fixed on the support 21. The entire unit 2 can be moved horizontally on the chassis 1. Generally the axis 24 is perpendicular to the axis 51. The unit can be tilted without the plane of the chassis 1 relative to the axis of wire feed 51.

Chaque unité rotative 3 ou 4 comprend un boîtier 31 ou 41 assurant le guidage en rotation et translation d'une broche cylindrique 32 ou 42 constituant une tête rotative de cambrage du fil. Cette broche présente un pion central 33 ou 43 et un pion excentré d'entraînement 34 ou 44. Par rotation de la broche autour de l'axe 35 ou 45, cette tête permet de réaliser sur le fil un pli suivant un angle de 0 à 270°.Each rotary unit 3 or 4 comprises a housing 31 or 41 ensuring the guiding in rotation and translation of a cylindrical spindle 32 or 42 constituting a rotary head for bending the wire. This pin has a central pin 33 or 43 and an eccentric drive pin 34 or 44. By rotation of the pin around the axis 35 or 45, this head makes it possible to produce a fold on the wire at an angle of 0 to 270 °.

La broche 32 ou 43 peut être déplacée en translation selon 35 ou 45 par un actionneur linéaire 36 ou 46 fixé au boîtier 31 ou 41.The spindle 32 or 43 can be moved in translation along 35 or 45 by a linear actuator 36 or 46 fixed to the housing 31 or 41.

L'entraînement en rotation de la broche 32 ou 42 est assuré par un actionneur rotatif 37 ou 47 monté sur les parties fixes de la machine.The spindle 32 or 42 is driven in rotation by a rotary actuator 37 or 47 mounted on the fixed parts of the machine.

Le boîtier 31 ou 41 est monté sur un berceau-support orientable 39 ou 49 de manière à être orientable autour de l'axe d'alimentation 51 du fil.The housing 31 or 41 is mounted on an orientable support cradle 39 or 49 so as to be orientable around the feed axis 51 of the wire.

L'actionneur est relié à la broche par l'intermédiaire d'une liaison homocinétique à cardans 38 ou 48. Cette liaison permet les réglages en position des unités rotatives.The actuator is connected to the spindle via a constant velocity connection with cardan joints 38 or 48. This connection allows adjustments in position of the rotary units.

Lorsque les axes des deux broches des unités 3 et 4 sont situés dans deux plans formant un dièdre, la machine produit des plis dans des plans différents.When the axes of the two pins of units 3 and 4 are located in two planes forming a dihedral, the machine produces folds in different planes.

Il est possible de placer un butée fixe sur le boîtier de l'unité à proximité de la broche afin de réaliser un contre-cambrage en fin de rotation.It is possible to place a fixed stop on the unit housing near the spindle in order to achieve a counter-bending at the end of rotation.

Chaque unité 3 ou 4 peut être déplacée selon l'axe 51.Each unit 3 or 4 can be moved along axis 51.

La largeur réduite des boîtiers 31 et 41 et les liaisons homocinétiques permettent de réaliser des cambrages rapprochés en plaçant des unités côte à côte.The reduced width of the boxes 31 and 41 and the constant velocity connections make it possible to produce close bends by placing units side by side.

Le fonctionnement va maintenant être expliqué.The operation will now be explained.

L'unité de cambrage 2 assure le pliage du fil 5 dans un plan. Elle assure le maintien du fil pendant le cambrage réalisé par les unités rotatives 3 et 4.The bending unit 2 folds the wire 5 in a plane. It maintains the wire during the bending carried out by the rotary units 3 and 4.

Les unités rotatives 3 et 4 sont ensuite actionnées dans un ordre déterminé par la forme finale de la pièce.The rotary units 3 and 4 are then actuated in an order determined by the final shape of the part.

Il est bien entendu que l'on peut sans sortir du cadre de l'invention imaginer des variantes et des perfectionnements de détails et de même envisager l'emploi de moyens équivalents. Le nombre d'unités est adapté à la forme désirée.It is understood that it is possible, without departing from the scope of the invention, to imagine variants and refinements of details and even to envisage the use of equivalent means. The number of units is adapted to the desired shape.
