Definitions
- the present invention relates to the production of a electric coil whose layers of turns are radial and alternately wound from the inside to the outside and from outside to inside.
- An object of the present invention is to provide a method of winding such radial layer coils, which is particularly simple to implement.
- Another object of the present invention is to provide such a process which allows, using a single device, make coils of variable internal and external diameters.
- the process includes the steps of forming around a core the layer with an internal diameter greater than diameter of the core, and to exert a traction on the internal whorl to tighten the layer on the core.
- the layer is formed by exerting an axial pressure on the turns during their winding.
- the method further comprises the steps of winding directly around the core the next layer from the inside outward by pressing on the exposed side of this layer; to axially offset the layers by the thickness of two layers; maintain the last layer on the periphery providing a support plan for a new layer; and to realize the new layer wound from the outside to the inside.
- the present invention also relates to an apparatus for implementing the above-mentioned method, comprising a crown radial surrounding the nucleus and defining with it a space winding a current layer; radial rollers extending to the core and urged towards the upper face of the crown; radial wedges movable between a position in contact with the core and a retracted position, these shims being shifted down from the top of the crown of a distance between a layer thickness and two layer thicknesses; and means for lifting the crown compared to the core of two layer thicknesses.
- the crown has retractable platforms associated with rollers to allow the rollers to lower.
- the apparatus includes a wire feeder for supplying the turns during winding at one of the rollers, the debtor being capable of selectively exerting traction or axial pressure on the wire.
- the rollers are conical, their largest diameter being side of the nucleus.
- the rollers are fixed and the whole of the crown, shims and the nucleus is rotating.
- An essential aspect of the winding process according to the invention lies in the production of the wound layers of outside to inside.
- the inner diameter of the layer is inevitably larger than the diameter of the nucleus of the future coil. So, we pull the last turn, that is to say the inner coil, to tighten the whole of the layer on the core, this core can be of section and any diameter.
- Figures 1 and 2A show a top view and a partial side view in section of an embodiment winding apparatus for carrying out the method according to the invention.
- the core 10 of the future coil is arranged substantially in the center of a radial crown 12.
- the space between the core 10 and this crown 12 is intended to receive a layer 14 during winding.
- the internal diameter of the crown therefore determines the maximum external diameter of the coil.
- the upper face of layer 14 is held in place by radial rollers 16 (of which only three are shown) which are biased towards the upper face of the crown 12 and come into contact with the core 10. These rollers 16 slide axially in order to be able to modify the diameter of the core 10.
- the winding wire 14-1 comes tangentially from below one of the rollers 16. To facilitate the introduction of wire 14-1, we can provide an area without rollers in front of the roller which receives the wire.
- the underside of layer 14 is held in place by radial wedges 18 regularly distributed around the core 10 below the crown 12.
- Each of these wedges 18 is movable between a position of contact with the core 10 and a position retracted where the inner end of the wedge is located substantially at the level of the internal diameter of the crown 12. The stroke of these shims 18 and of the rollers 16 determines the minimum core diameter 10.
- the assembly of the crown 12, the core 10, and the shims 18 is likely to be rotated about the axis of the core while the rollers 16 are fixed.
- the rollers 16 are preferably conical, the most large diameter being on the side of the core 10.
- the rollers 16 are then tilted to provide a horizontal plane to maintain the wound layer 14. As a result, the contact zone between each roller 16 and the core 10 is reduced to a point, which reduces friction.
- the crown 12 includes platforms 20 which can be brought into correspondence with the rollers 16 by a rotation of the crown 12. These platforms 20 are retractable down to allow the rollers 16 to lower to reach the plane of the holds 18.
- the wire 14-1 is rectangular or square. We would prefer such a choice, because it facilitates the adjustment of the device according to the section of the wire.
- the distance between the rollers 16 and the shims 18 can then be freely adjusted between once and twice the wire height. It is thus possible, with a single adjustment, to wind wires varying in height from single or double.
- the height of the shims 18 must be adjusted so that the distance separating them rollers 16 is substantially equal to the diameter of the wire, this to prevent the turns of the same layer from overlapping.
- Figures 1 and 2A illustrate a first step in winding of a first layer from the outside to the inside.
- the rollers 16 are in contact with the upper face of the crown 12 and the shims 18 are supported on the core 10.
- the crown 12 (as well as the shims 18 and the core 10) is set clockwise rotation, for example.
- a debtor, no shown, provides wire 14-1 with some axial pressure P in the direction of rotation of the crown 12. This pressure P is chosen so that the turns being wound have tends to move away from the nucleus 10.
- the first turn has tendency to press against the internal diameter of the crown 12 and each subsequent turn tends, as is shown, to be pressed inside the previous turn.
- the layer that we just wound normally has a diameter internal greater than the diameter of the nucleus.
- the next step, illustrated in Figure 2B, is to pull T on wire 14-1 until the layer which has just been wound up tightens on the core 10.
- This traction T is preferably exerted by stopping the crown 12 and operating the debtor in reverse. According to one variant, traction T could be obtained by braking the debtor while the crown 12 continues to rotate.
- the crown 12 performs, if necessary if necessary, a fraction of a turn to bring platforms 20 into correspondence with the rollers 16. So the platforms 20 are lowered while the wedges 18 are retracted. In practical, the layers we just wound are so tight on core 10 that they cannot slide down under the force of the rollers 16. Furthermore, this sliding is not desirable because it could damage the insulation of the turns interior.
- the crown 12 is offset relative to the core 10 the height of two layers, as shown. For this, the crown 12 is lifted, for example, by a jack with position adjustable by digital control. Alternatively, the core 10 could be lowered, which would however disadvantage of doubling the overall height of the device the fact that the core 10 should move to one side and the other from crown 12.
- the shims 18 are slid towards the core 10 and the platforms 20 are then lifted to their initial position.
- the internal ends of the shims 18 come abut against the outer coil of the last wound layer and maintain this layer which would otherwise tend to unfold.
- the device is then ready to repeat the step illustrated in Figure 2A to wind a new layer of outside to inside.
- Each layer can be made to a diameter different. This possibility has the advantage of allowing the creation of intermediate output terminals for which the total number of turns is not a multiple of the number of turns nominal layers.
- the thickness of the shims 18 is chosen to be less than the thickness of the layers. So the holds can still reach the outside diameter of this layer at the Figure 2F.
- the crown 12 is continuous, that is to say devoid of retractable wedges 20.
- a set of pressers is provided which press on the new layer wound in the defined space between the rollers 16, the core 10, and the internal diameter of the crown 12. These pressers descend at the same time as the rollers and continue to descend when rollers 16 abut on the upper face of the crown 12, to bring the last layer wound at the level of the radial shims 18 in FIG. 2E.
- the translational displacements of the various elements of the apparatus, except of the core 10, are ensured by jacks tires, for example.
- the rotation can be ensured by a DC motor.

Description
La présente invention concerne la réalisation d'une bobine électrique dont les couches de spires sont radiales et bobinées alternativement de l'intérieur vers l'extérieur et de l'extérieur vers l'intérieur.The present invention relates to the production of a electric coil whose layers of turns are radial and alternately wound from the inside to the outside and from outside to inside.
Lorsque de telles bobines sont utilisées dans des applications haute tension, par exemple dans des transformateurs, elles présentent l'avantage de ne nécessiter aucun isolant entre couches de spires. Ce résultat est obtenu grâce au fait que deux spires adjacentes de deux couches successives ne sont séparées que par un faible nombre de tours, de sorte qu'elles sont soumises à une différence de potentiel relativement basse ne nécessitant pas l'interposition d'un isolant entre les deux couches.When such coils are used in high voltage applications, for example in transformers, they have the advantage of not requiring any insulation between layers of turns. This is achieved due to the fact that two adjacent turns of two successive layers are not separated only by a small number of turns, so that they are subject to a relatively low potential difference does not requiring the interposition of an insulation between the two layers.
Un objet de la présente invention est de prévoir un procédé de bobinage de telles bobines à couches radiales, qui soit particulièrement simple à mettre en oeuvre.An object of the present invention is to provide a method of winding such radial layer coils, which is particularly simple to implement.
Un autre objet de la présente invention est de prévoir un tel procédé qui permette, à l'aide d'un appareil unique, de réaliser des bobines de diamètres internes et externes variables.Another object of the present invention is to provide such a process which allows, using a single device, make coils of variable internal and external diameters.
Ces objets sont atteints selon l'invention grâce à un procédé de bobinage de spires en couches radiales bobinées alternativement de l'extérieur vers l'intérieur et de l'intérieur vers l'extérieur. Pour bobiner une couche de l'extérieur vers l'intérieur, le procédé comprend les étapes consistant à former autour d'un noyau la couche avec un diamètre interne supérieur au diamètre du noyau, et à exercer une traction sur la spire interne pour resserrer la couche sur le noyau.These objects are achieved according to the invention thanks to a winding process of coils in wound radial layers alternately from outside to inside and from inside outwards. To wind a layer from the outside to inside, the process includes the steps of forming around a core the layer with an internal diameter greater than diameter of the core, and to exert a traction on the internal whorl to tighten the layer on the core.
Selon un mode de réalisation de la présente invention, la couche est formée en exerçant une pression axiale sur les spires pendant leur bobinage.According to an embodiment of the present invention, the layer is formed by exerting an axial pressure on the turns during their winding.
Selon un mode de réalisation de la présente invention, le procédé comprend en outre les étapes consistant à bobiner directement autour du noyau la couche suivante de l'intérieur vers l'extérieur en exerçant une pression sur la face exposée de cette couche ; à décaler axialement les couches de l'épaisseur de deux couches ; à maintenir en périphérie la dernière couche en fournissant un plan d'appui à une nouvelle couche ; et à réaliser la nouvelle couche bobinée de l'extérieur vers l'intérieur.According to an embodiment of the present invention, the method further comprises the steps of winding directly around the core the next layer from the inside outward by pressing on the exposed side of this layer; to axially offset the layers by the thickness of two layers; maintain the last layer on the periphery providing a support plan for a new layer; and to realize the new layer wound from the outside to the inside.
La présente invention vise également un appareil pour mettre en oeuvre le procédé susmentionné, comprenant une couronne radiale entourant le noyau et définissant avec celui-ci un espace de bobinage d'une couche courante ; des rouleaux radiaux s'étendant jusqu'au noyau et sollicités vers la face supérieure de la couronne ; des cales radiales mobiles entre une position en contact avec le noyau et une position escamotée, ces cales étant décalées vers le bas par rapport à la face supérieure de la couronne d'une distance comprise entre une épaisseur de couche et deux épaisseurs de couche ; et des moyens pour lever la couronne par rapport au noyau de deux épaisseurs de couche.The present invention also relates to an apparatus for implementing the above-mentioned method, comprising a crown radial surrounding the nucleus and defining with it a space winding a current layer; radial rollers extending to the core and urged towards the upper face of the crown; radial wedges movable between a position in contact with the core and a retracted position, these shims being shifted down from the top of the crown of a distance between a layer thickness and two layer thicknesses; and means for lifting the crown compared to the core of two layer thicknesses.
Selon un mode de réalisation de la présente invention, la couronne comporte des plates-formes escamotables associées aux rouleaux pour permettre aux rouleaux de s'abaisser.According to an embodiment of the present invention, the crown has retractable platforms associated with rollers to allow the rollers to lower.
Selon un mode de réalisation de la présente invention, l'appareil comprend un débiteur de fil pour alimenter les spires en cours de bobinage au niveau de l'un des rouleaux, le débiteur étant susceptible d'exercer sélectivement une traction ou une pression axiale sur le fil. According to an embodiment of the present invention, the apparatus includes a wire feeder for supplying the turns during winding at one of the rollers, the debtor being capable of selectively exerting traction or axial pressure on the wire.
Selon un mode de réalisation de la présente invention, les rouleaux sont coniques, leur plus grand diamètre étant du côté du noyau.According to an embodiment of the present invention, the rollers are conical, their largest diameter being side of the nucleus.
Selon un mode de réalisation de la présente invention, les rouleaux sont fixes et l'ensemble de la couronne, des cales et du noyau est tournant.According to an embodiment of the present invention, the rollers are fixed and the whole of the crown, shims and the nucleus is rotating.
Ces objets, caractéristiques et avantages, ainsi que
d'autres de la présente invention seront exposés en détail dans
la description suivante de modes de réalisation particuliers
faite à titre non-limitatif en relation avec les figures jointes
parmi lesquelles :
Un aspect essentiel du procédé de bobinage selon l'invention réside dans la réalisation des couches bobinées de l'extérieur vers l'intérieur. Pour réaliser une telle couche selon l'invention, on commence par la bobiner de l'extérieur vers l'intérieur à partir d'un diamètre extérieur supérieur au diamètre extérieur de la future bobine. Ceci est réalisé avantageusement en exerçant une pression axiale sur la spire en cours de bobinage, de manière que l'ensemble de la couche ait tendance à s'agrandir. Une fois que le nombre de spires de la couche a été atteint, le diamètre intérieur de la couche est inévitablement plus grand que le diamètre du noyau de la future bobine. Alors, on exerce une traction sur la dernière spire, c'est-à-dire la spire intérieure, pour resserrer l'ensemble de la couche sur le noyau, ce noyau pouvant être de section et de diamètre quelconque.An essential aspect of the winding process according to the invention lies in the production of the wound layers of outside to inside. To make such a layer according to the invention, we start by winding it from the outside towards the interior from an outside diameter greater than outer diameter of the future coil. This is achieved advantageously by exerting an axial pressure on the turn in winding course, so that the entire layer has tendency to get bigger. Once the number of turns of the layer has been reached, the inner diameter of the layer is inevitably larger than the diameter of the nucleus of the future coil. So, we pull the last turn, that is to say the inner coil, to tighten the whole of the layer on the core, this core can be of section and any diameter.
Les figures 1 et 2A représentent une vue de dessus et
une vue partielle de côté en coupe d'un mode de réalisation
d'appareil de bobinage permettant de mettre en oeuvre le procédé
selon l'invention. Le noyau 10 de la future bobine est disposé
sensiblement au centre d'une couronne radiale 12. L'espace entre
le noyau 10 et cette couronne 12 est destiné à recevoir une
couche 14 en cours de bobinage. Le diamètre interne de la
couronne détermine donc le diamètre externe maximal de la bobine.Figures 1 and 2A show a top view and
a partial side view in section of an embodiment
winding apparatus for carrying out the method
according to the invention. The
La face supérieure de la couche 14 est maintenue par
des rouleaux radiaux 16 (dont seulement trois sont représentés)
qui sont sollicités vers la face supérieure de la couronne 12 et
entrent en contact avec le noyau 10. Ces rouleaux 16 coulissent
axialement afin de pouvoir modifier le diamètre du noyau 10. Le
fil à bobiner 14-1 arrive tangentiellement par dessous l'un des
rouleaux 16. Pour faciliter l'introduction du fil 14-1, on pourra
prévoir un secteur dépourvu de rouleaux devant le rouleau qui
reçoit le fil.The upper face of
La face inférieure de la couche 14 est maintenue par
des cales radiales 18 régulièrement réparties autour du noyau 10
en dessous de la couronne 12. Chacune des ces cales 18 est mobile
entre une position de contact avec le noyau 10 et une position
escamotée où l'extrémité intérieure de la cale se trouve
sensiblement au niveau du diamètre intérieur de la couronne 12.
La course de ces cales 18 et des rouleaux 16 détermine le
diamètre minimal du noyau 10.The underside of
L'ensemble de la couronne 12, du noyau 10, et des cales
18 est susceptible d'être entraíné en rotation autour de l'axe du
noyau alors que les rouleaux 16 sont fixes. Comme cela est
représenté, les rouleaux 16 sont de préférence coniques, le plus
grand diamètre étant du côté du noyau 10. Les rouleaux 16 sont
alors inclinés pour offrir un plan horizontal de maintien à la
couche bobinée 14. Il en résulte que la zone de contact entre
chaque rouleau 16 et le noyau 10 est réduit à un point, ce qui
réduit les frottements.The assembly of the
La couronne 12 comporte des plates-formes 20 qui
peuvent être amenées en correspondance avec les rouleaux 16 par
une rotation de la couronne 12. Ces plates-formes 20 sont
escamotables vers le bas afin de permettre aux rouleaux 16 de
s'abaisser pour rejoindre le plan des cales 18.The
Comme cela est représenté à titre d'exemple, le fil 14-1
est rectangulaire ou carré. On préférera un tel choix, car il
facilite le réglage de l'appareil en fonction de la section du
fil. En effet, la distance séparant les rouleaux 16 des cales 18
peut alors être librement réglée entre une fois et deux fois la
hauteur du fil. On peut ainsi, avec un réglage unique, bobiner
des fils de hauteur variant du simple ou double.As shown by way of example, the wire 14-1
is rectangular or square. We would prefer such a choice, because it
facilitates the adjustment of the device according to the section of the
wire. The distance between the
Si le fil est de section circulaire, la hauteur des
cales 18 doit être réglée pour que la distance séparant celles-ci
des rouleaux 16 soit sensiblement égale au diamètre du fil, ceci
pour éviter que les spires d'une même couche ne se chevauchent.
Pour faciliter le bobinage d'un fil à section circulaire, on
préférera laminer le fil pour qu'il présente des méplats
parallèles à l'axe de bobinage, ce qui empêchera le
chevauchement.If the wire is of circular section, the height of the
Les figures 1 et 2A illustrent une première étape du
bobinage d'une première couche de l'extérieur vers l'intérieur.
Les rouleaux 16 sont en contact avec la face supérieure de la
couronne 12 et les cales 18 sont en appui sur le noyau 10. La
couronne 12 (ainsi que les cales 18 et le noyau 10) est mise en
rotation dans le sens horaire, par exemple. Un débiteur, non
représenté, fournit le fil 14-1 avec une certaine pression axiale
P dans le sens de la rotation de la couronne 12. Cette pression P
est choisie pour que les spires en cours de bobinage aient
tendance à s'écarter du noyau 10. Ainsi, la première spire a
tendance à se plaquer contre le diamètre interne de la couronne
12 et chaque spire suivante a tendance, comme cela est
représenté, à se plaquer à l'intérieur de la spire précédente.Figures 1 and 2A illustrate a first step in
winding of a first layer from the outside to the inside.
The
Lorsque le nombre souhaité de spires est atteint, la couche que l'on vient de bobiner présente normalement un diamètre interne supérieur au diamètre du noyau.When the desired number of turns is reached, the layer that we just wound normally has a diameter internal greater than the diameter of the nucleus.
L'étape suivante, illustrée à la figure 2B, consiste à
exercer une traction T sur le fil 14-1 jusqu'à ce que la couche
qui vient d'être bobinée se resserre sur le noyau 10. Cette
traction T est de préférence exercée en arrêtant la couronne 12
et en faisant fonctionner le débiteur en sens inverse. Selon une
variante, la traction T pourrait être obtenue en freinant le
débiteur alors que la couronne 12 continue à tourner.The next step, illustrated in Figure 2B, is to
pull T on wire 14-1 until the layer
which has just been wound up tightens on the
Comme cela est représenté aux figures 2A et 2B, si
l'écart entre les rouleaux 16 et les cales 18 est supérieur à la
hauteur du fil, les spires que l'on obtient ne sont généralement
pas dans le même plan. Ceci n'est pas gênant, comme on le verra
ci-après.As shown in Figures 2A and 2B, if
the distance between the
A la figure 2C, la couche qui vient d'être bobinée de
l'extérieur vers l'intérieur vient d'être resserrée autour du
noyau 10 et la couronne 12 tourne dans le sens horaire. La spire
en cours de bobinage 14-1, par manque de place, monte sur la
dernière spire, interne, de la couche que l'on vient de bobiner
et soulève les rouleaux 16. En effet, ces rouleaux 16 coulissent
verticalement et sont sollicités vers le bas élastiquement ou
simplement par gravité. Ainsi, la spire en cours de bobinage et
la spire qui se trouve immédiatement en dessous sont forcées vers
les cales 18 sous la pression exercée par les rouleaux 16. Les
spires successives vont s'enrouler de l'intérieur vers
l'extérieur tout en alignant les spires de la couche précédente.In FIG. 2C, the layer which has just been wound with
the outside towards the inside has just been tightened around the
A la figure 2D, le nombre de spires souhaité pour la deuxième couche est atteint. Comme cela est représenté, les deux couches que l'on vient de bobiner sont parfaitement plates.In Figure 2D, the number of turns desired for the second layer is reached. As shown, the two layers that we just wound are perfectly flat.
A la figure 2E, la couronne 12 effectue, le cas
échéant, une fraction de tour pour amener des plates-formes 20 en
correspondance avec les rouleaux 16. Alors, les plates-formes 20
sont abaissées tandis que les cales 18 sont escamotées. En
pratique, les couches que l'on vient de bobiner sont si serrées
sur le noyau 10 qu'elles ne peuvent pas glisser vers le bas sous
l'effort des rouleaux 16. Par ailleurs, ce glissement n'est pas
souhaitable car il risquerait d'endommager l'isolant des spires
intérieures. Par contre, on décale la couronne 12 par rapport au
noyau 10 de la hauteur de deux couches, comme cela est illustré.
Pour cela, la couronne 12 est levée, par exemple, par un vérin à
position réglable par commande numérique. Selon une variante, le
noyau 10 pourrait être abaissé, ce qui aurait toutefois pour
inconvénient de doubler l'encombrement en hauteur de l'appareil
du fait que le noyau 10 devrait se déplacer d'un côté et de
l'autre de la couronne 12.In FIG. 2E, the
A la figure 2F, les cales 18 sont glissées vers le
noyau 10 et les plates-formes 20 sont ensuite levées jusqu'à leur
position initiale. Les extrémités internes des cales 18 viennent
buter contre la spire externe de la dernière couche bobinée et
assurent le maintien de cette couche qui aurait sinon tendance à
se dérouler.In FIG. 2F, the
L'appareil se trouve alors prêt à recommencer l'étape illustrée à la figure 2A pour bobiner une nouvelle couche de l'extérieur vers l'intérieur.The device is then ready to repeat the step illustrated in Figure 2A to wind a new layer of outside to inside.
Chaque couche peut être réalisée à un diamètre différent. Cette possibilité présente l'avantage de permettre la création de bornes de sortie intermédiaires pour lesquelles le nombre total de spires n'est pas un multiple du nombre de spires nominal des couches.Each layer can be made to a diameter different. This possibility has the advantage of allowing the creation of intermediate output terminals for which the total number of turns is not a multiple of the number of turns nominal layers.
Pour permettre la réalisation d'une couche de diamètre
inférieur à celui de la couche précédente au niveau de l'étape de
la figure 2D, l'épaisseur des cales 18 est choisie inférieure à
l'épaisseur des couches. Alors, les cales pourront toujours
atteindre le diamètre extérieur de cette couche à l'étape de la
figure 2F.To allow the realization of a diameter layer
lower than that of the previous layer at the step of
FIG. 2D, the thickness of the
Selon une variante avantageuse (non représentée) de
l'appareil, la couronne 12 est continue, c'est-à-dire dépourvue
des cales escamotables 20. Alors, pour passer de l'étape de la
figure 2D à celle de la figure 2E, on prévoit un jeu de presseurs
qui appuient sur la nouvelle couche bobinée dans l'espace défini
entre les rouleaux 16, le noyau 10, et le diamètre interne de la
couronne 12. Ces presseurs descendent en même temps que les
rouleaux et continuent à descendre lorsque les rouleaux 16 butent
sur la face supérieure de la couronne 12, pour amener la dernière
couche bobinée au niveau des cales radiales 18 à la figure 2E.According to an advantageous variant (not shown) of
the device, the
Les déplacements en translation des divers éléments de l'appareil, sauf du noyau 10, sont assurés par des vérins pneumatiques, par exemple. La rotation pourra être assurée par un moteur à courant continu.The translational displacements of the various elements of the apparatus, except of the core 10, are ensured by jacks tires, for example. The rotation can be ensured by a DC motor.
Dans la description qui précède, on a supposé à titre
d'exemple que le noyau 10 était de section circulaire. Il peut
bien entendu être de section quelconque.In the above description, it has been assumed as
example that the
De nombreuses variantes et modifications de la présente invention apparaítront à l'homme du métier. Par exemple, on peut bobiner en même temps plusieurs fils en parallèle.Many variations and modifications to this invention will appear to those skilled in the art. For example, we can wind several wires at the same time.
