Description

Dispositif et procédé de fixation d' un système d' amorçage sur un corps d' ne grenade Device and method for fixing a priming system on a body of a grenade
Le domaine technique de la présente invention est celui des dispositifs permettant la fixation d'un système d'amorçage sur un corps d'une grenade, notamment d'une grenade à charge formée destinée à être emportée et dispersée sur trajectoire par un projectile (obus ou roquette) .The technical field of the present invention is that of devices allowing the fixing of a priming system on a body of a grenade, in particular of a grenade with a shaped charge intended to be carried and dispersed on trajectory by a projectile (shell or rocket).
Les systèmes d'amorçage de telles grenades sont généralement fixés au corps de la grenade par rivetage ou vissage.The priming systems of such grenades are generally fixed to the body of the grenade by riveting or screwing.
Le brevet US3913483 décrit ainsi un système d'amorçage fixé par rivetage.US Pat. No. 3,913,483 thus describes a priming system fixed by riveting.
Un tel dispositif de fixation ne permet pas de remplacer facilement le système d'amorçage par un nouveau système, par exemple un système plus performant, incorporant par exemple un dispositif d' autodestruction.Such a fixing device does not allow the priming system to be easily replaced by a new system, for example a more efficient system, incorporating for example a self-destruct device.
Les rivets doivent être coupés et ils ne peuvent plus alors être employés pour fixer un nouveau système d'amorçage.The rivets must be cut and they can no longer be used to fix a new priming system.
Le corps de grenade ne peut être réutilisé et la grenade doit être complètement remplacée.The grenade body cannot be reused and the grenade must be completely replaced.
Le but de la présente invention est de fournir un dispositif de fixation d'un système d'amorçage sur un corps de grenade qui permette, d'une façon sûre et économique, un remplacement ultérieur du système d'amorçage.The object of the present invention is to provide a device for fixing a priming system on a grenade body which allows, in a safe and economical manner, a subsequent replacement of the priming system.
L'invention a également pour objet un procédé permettant de solidariser facilement un système d'amorçage et un corps de grenade. Le procédé selon l'invention permet également d'assurer une telle solidarisation dans le cadre d'une opération de remise à niveau d'un stock de grenades.The invention also relates to a method for easily securing a priming system and a grenade body. The method according to the invention also makes it possible to ensure such a joining in the context of an operation to upgrade a stock of grenades.
Il autorise en effet le remplacement d'un système d'amorçage ancien par un nouveau système d'amorçage, même si ce dernier présente des formes, des matériaux et des dimensions différentes de celles de l'ancien système d' amorçage. Ainsi l'invention a pour objet un dispositif de fixation d'un système d'amorçage sur un corps d'une grenade, dispositif caractérisé en ce qu'il est constitué par un support rendu solidaire par un moyen de fixation du corps de la grenade, support comportant une paroi cylindrique mince dont un rebord supérieur est serti sur le système d'amorçage.It authorizes the replacement of an old priming system with a new priming system, even if the latter has different shapes, materials and dimensions from those of the old priming system. Thus the subject of the invention is a device for fixing a priming system on a body of a grenade, device characterized in that it is constituted by a support made integral by a means of fixing the body of the grenade , support comprising a thin cylindrical wall, an upper edge of which is crimped onto the priming system.
Selon un premier mode de réalisation, le support pourra être constitué par une coupelle présentant une paroi de fond solidaire de la paroi cylindrique et disposée en appui sur une face supérieure du corps de grenade.According to a first embodiment, the support may consist of a cup having a bottom wall secured to the cylindrical wall and disposed in abutment on an upper face of the grenade body.
La coupelle présentera par exemple au moins deux trous autorisant le passage de tiges solidaires du corps de grenade. La coupelle pourra être rendue solidaire des tiges par soudure.The cup will present for example at least two holes allowing the passage of rods integral with the grenade body. The cup can be made integral with the rods by welding.
Selon un deuxième mode de réalisation, le support pourra être constitué par un tube qui est fixé par soudure au niveau d'une paroi externe du corps. La paroi externe sur laquelle sera fixé le tube pourra comporter un épaulement constituant une butée pour le tube.According to a second embodiment, the support may consist of a tube which is fixed by welding at an external wall of the body. The external wall on which the tube will be fixed may include a shoulder constituting a stop for the tube.
La paroi externe sur laquelle est fixé le tube pourra être arrondie, l'extrémité du tube présentant alors une partie évasée et un chanfrein. L'invention a également pour objet un procédé de fixation d'un système d'amorçage sur un corps d'une grenade, procédé caractérisé par les étapes suivantes :The external wall on which the tube is fixed may be rounded, the end of the tube then having a flared part and a chamfer. The subject of the invention is also a method of fixing a priming system on a body of a grenade, a method characterized by the following steps:
-on découpe une portion d'un tube métallique,-a portion of a metal tube is cut,
-on coiffe avec cette portion de tube une partie d'une surface externe d'un corps de grenade,-with this portion of tube, part of an external surface of a pomegranate body is capped,
-on fixe par soudure la portion de tube au corps de grenade,-the tube portion is fixed by welding to the grenade body,
-on dispose le système d'amorçage à l'intérieur du tube, -on sertit le tube sur le système d'amorçage.- the priming system is placed inside the tube, - the tube is crimped onto the priming system.
L'invention a également pour objet un autre procédé de fixation d'un système d'amorçage sur un corps d'une grenade, procédé caractérisé par les étapes suivantes : -on découpe une portion d'un tube métallique,Another subject of the invention is another method of attaching a priming system to a body of a grenade, a method characterized by the following steps: -a portion of a metal tube is cut,
-on réalise une collerette formant butée de sertissage à une extrémité du tube, avant de le disposer autour d'un système d'amorçage ou bien après l'avoir disposé autour du système d'amorçage,a flange forming a crimping stop is produced at one end of the tube, before placing it around a priming system or after having placed it around the priming system,
-on coiffe une partie d'une surface externe d'un corps de grenade avec le tube portant le système d'amorçage,-a part of an external surface of a grenade body is capped with the tube carrying the priming system,
-on fixe par soudure la portion de tube au corps de grenade.-the tube portion is fixed by welding to the grenade body.
Avantageusement, lorsque la partie du corps de grenade sur laquelle vient s'appliquer le tube se trouve arrondie, on procédera à un léger évasement de l'extrémité du tube avant ou lors du positionnement du tube sur le corps de grenade, cela afin d'élargir la surface de contact relative entre tube et corps de grenade.Advantageously, when the part of the grenade body on which the tube is applied is rounded, there will be a slight flaring of the end of the front tube or when positioning the tube on the grenade body, this in order to widen the relative contact surface between the tube and the grenade body.
La soudure pourra être réalisée par laser.Welding can be performed by laser.
La soudure laser pourra être réalisée de façon à couper une extrémité du tube de façon à aménager un chanfrein d'extrémité à cette extrémité du tube.Laser welding can be performed so as to cut one end of the tube so as to provide an end chamfer at this end of the tube.
D'autres avantages de l'invention apparaîtront à la lecture de la description qui va suivre de différents modes de réalisation, description faite en référence aux dessins annexés et dans lesquels : - la figure 1 représente schématiquement et en coupe partielle une grenade portant un système d'amorçage fixé par un dispositif de fixation selon l'art antérieur,Other advantages of the invention will appear on reading the description which follows of different embodiments, description made with reference to the accompanying drawings and in which: - Figure 1 shows schematically and in partial section a grenade carrying a system priming fixed by a fixing device according to the prior art,
- la figure 2 représente un premier mode de réalisation d'un dispositif de fixation selon l'invention, - la figure 3 représente un deuxième mode de réalisation d'un dispositif de fixation selon l'invention,FIG. 2 represents a first embodiment of a fixing device according to the invention, FIG. 3 represents a second embodiment of a fixing device according to the invention,
- la figure 4 montre les différentes étapes du procédé de fixation selon l'invention,FIG. 4 shows the different stages of the fixing method according to the invention,
- les figures 5a et 5b sont deux vues de détails de deux variantes de réalisation de la soudure du tube sur le corps de grenade.- Figures 5a and 5b are two detail views of two alternative embodiments of the welding of the tube on the grenade body.
La figure 1 montre une grenade 1 de type connu (telle que décrite par exemple par le brevet US3913483. Elle comporte un corps 2 métallique qui renferme un chargement explosif 3 sur lequel est appliqué un revêtement métallique 4 sensiblement conique. Un système d'amorçage 5, d'un type connu et dont seul le profil externe est représenté ici, est fixé au corps 2 de la grenade par un dispositif de fixation qui comprend quatre rivets 6 régulièrement répartis angulairement (ici seuls deux rivets sont visibles) .Figure 1 shows a grenade 1 of known type (as described for example by US Pat. No. 3,913,483. comprises a metallic body 2 which contains an explosive charge 3 on which a metallic coating 4 is applied which is substantially conical. A priming system 5, of a known type and of which only the external profile is shown here, is fixed to the body 2 of the grenade by a fixing device which comprises four rivets 6 regularly distributed angularly (here only two rivets are visible ).
Les rivets 6 traversent une face supérieure 7 du corps 2 de grenade par des trous 8. La tête 6a des rivets est noyée dans le chargement explosif 3. La queue déformable 6b des rivets 6 est appliquée sur le système d'amorçage 5.The rivets 6 pass through an upper face 7 of the grenade body 2 through holes 8. The head 6a of the rivets is embedded in the explosive charge 3. The deformable tail 6b of the rivets 6 is applied to the priming system 5.
Avec ce dispositif de fixation connu, il est difficile de procéder au remplacement du système d' amorçage par un autre système d'amorçage plus performant.With this known fixing device, it is difficult to replace the priming system with another more efficient priming system.
Les queues 6b des rivets doivent être tout d'abord découpées pour retirer le système d'amorçage 5. Les rivets raccourcis sont alors difficilement utilisables pour fixer un autre système d'amorçage. De plus la géométrie de ce dernier doit être adaptée pour permettre une coopération avec les rivets.The shanks 6b of the rivets must first be cut to remove the priming system 5. The shortened rivets are then difficult to use for fixing another priming system. In addition the geometry of the latter must be adapted to allow cooperation with the rivets.
On notera qu'il n'est pas possible de remplacer les rivets 6 car une telle opération impose le déchargement de l'explosif 3 ce qui est coûteux et dangereux. La figure 2 montre un premier mode de réalisation d'un dispositif de fixation selon l'invention.Note that it is not possible to replace the rivets 6 because such an operation requires the unloading of the explosive 3 which is costly and dangerous. FIG. 2 shows a first embodiment of a fixing device according to the invention.
Suivant ce mode de réalisation, le système d'amorçage 5 est rendu solidaire du corps 2 de grenade par l'intermédiaire d'un support 9 métallique comportant une paroi cylindrique mince 10 dont un rebord supérieur 11 est serti sur le système d'amorçage 5.According to this embodiment, the priming system 5 is made integral with the body 2 of the grenade by means of a metallic support 9 comprising a thin cylindrical wall 10, an upper edge 11 of which is crimped onto the priming system 5 .
Le support 9 est constitué par une coupelle présentant une paroi de fond 12 solidaire de la paroi cylindrique 10 et disposée en appui sur la face supérieure 7 du corps 2 de grenade.The support 9 consists of a cup having a bottom wall 12 secured to the cylindrical wall 10 and disposed in abutment on the upper face 7 of the body 2 of the grenade.
La coupelle 9 sera réalisée par exemple en tôle d'acier emboutie de 1 mm d'épaisseur. Elle comporte des trous 13 autorisant le passage des tiges des rivets 6 solidaires du corps 2 de grenade.The cup 9 will be made for example from stamped sheet steel 1 mm thick. It has holes 13 allowing the passage of the rods of the rivets 6 secured to the body 2 of the grenade.
Suivant une première variante, on assurera la solidarisation de la coupelle 9 et du corps 2 en sertissant les extrémités 6b des rivets 6 sur la coupelle 9 (voir le rivet de droite sur la figure 2) . Dans ce cas on aura procédé au préalable à une découpe des rivets 6 à une longueur appropriée permettant le sertissage sur la coupelle mince 9.According to a first variant, the cup 9 and the body 2 will be secured together by crimping the ends 6b of the rivets 6 on the cup 9 (see the right rivet in FIG. 2). In this case, the rivets 6 will have been cut beforehand to an appropriate length allowing crimping on the thin cup 9.
L'épaisseur de la coupelle est de l'ordre de 1 mm, il est donc facile de raccourcir les rivets rencontrés habituellement (qui ont une longueur de l'ordre de 10mm) de façon à leur donner une dimension appropriée au sertissage. II est par contre nécessaire de prévoir dans le système d'amorçage 5 un dégagement 14 évitant toute interférence avec les queues 6b des rivets.The thickness of the cup is of the order of 1 mm, it is therefore easy to shorten the rivets usually encountered (which have a length of the order of 10 mm) so as to give them an appropriate dimension for crimping. It is however necessary to provide in the priming system 5 a clearance 14 avoiding any interference with the tails 6b of the rivets.
Suivant une deuxième variante (voir le rivet de gauche sur la figure 2) on pourra découper les rivets 6 de façon à ce que leur extrémité affleure au niveau de l'intérieur de la coupelle 9. On procédera ensuite à la fixation de la coupelle 9 par soudure, par exemple par laser, des extrémités des rivets sur la coupelle.According to a second variant (see the left rivet in FIG. 2), the rivets 6 can be cut so that their end is flush with the interior of the cup 9. We will then fix the cup 9 by welding, for example by laser, the ends of the rivets on the cup.
La soudure laser sera réalisée en provoquant un echauffement de la coupelle et du rivet le long de la ligne de contact circulaire du rivet 6 avec le trou 13 dans la coupelle 9.The laser welding will be carried out by causing the cup and the rivet to heat up along the circular contact line of the rivet 6 with the hole 13 in the cup 9.
Avec cette variante il n'y a plus d'interférences entre les tiges de rivets et le système d'amorçage. On voit qu'il est possible grâce au dispositif de fixation selon l'invention de remplacer un système d' amorçage tel que celui selon la figure 1 par un autre système d'amorçage. Les rivets sont réutilisés sans qu'il soit nécessaire de retirer l'explosif du corps de grenade. De plus la coupelle permet la fixation d'un système d'amorçage, de forme et structure quelconque, sur le corps de la grenade. Il permet également de fixer facilement un système d'amorçage dont la structure sera réalisée en matériaux très différents de ceux du corps de grenade par exemple en matière plastique ou en alliage de zinc/aluminium (alliages bien connus sous la marque zamak) . Le dispositif selon l'invention peut être également utilisé pour une grenade neuve. Il autorisera un remplacement ultérieur du système d'amorçage par un autre système. Il suffira de procéder au dessertissage du rebord 11 de la coupelle pour démonter le système d'amorçage. Un nouveau système pourra être remis en place et la coupelle sera re-sertie.With this variant there is no longer any interference between the rivet rods and the priming system. We see that it is possible thanks to the fixing device according to the invention to replace a priming system such as that according to Figure 1 by another priming system. The rivets are reused without the need to remove the explosive from the grenade body. In addition the cup allows the attachment of a priming system, of any shape and structure, on the body of the grenade. It also makes it easy to fix a priming system, the structure of which will be made in materials very different from those of the grenade body, for example plastic or zinc / aluminum alloy (alloys well known under the brand zamak). The device according to the invention can also be used for a new grenade. It will authorize a subsequent replacement of the boot system by another system. It will suffice to proceed with the desoldering of the rim 11 of the cup to dismantle the priming system. A new system can be replaced and the cup will be refilled.
A titre de variante on pourra réaliser une coupelle 9 dépourvue de trous 13 et qui sera rendue solidaire de la face supérieure 7 du corps 2 de grenade par collage ou bien par echauffement par points (soudure par arc électrique) .As a variant, it will be possible to produce a cup 9 devoid of holes 13 and which will be made integral with the upper face 7 of the body 2 of the grenade by gluing or else by spot heating (welding by electric arc).
La figure 3 montre un deuxième mode de réalisation d'un dispositif de fixation selon l'invention.Figure 3 shows a second embodiment of a fixing device according to the invention.
Suivant ce mode le support 9 est constitué par un tube qui est fixé par soudure au niveau d'une paroi externe du corps 2.According to this mode, the support 9 is constituted by a tube which is fixed by welding at an external wall of the body 2.
La figure 5b montre de façon agrandie l'extrémité du tube 9 qui est soudée au corps 2. Dans ce cas particulier la paroi externe 15 du corps 2 sur laquelle est fixé le tube 9 est arrondie. L'extrémité du tube 9 présente une partie évasée 16 et un chanfrein 17.FIG. 5b shows in an enlarged manner the end of the tube 9 which is welded to the body 2. In this particular case the external wall 15 of the body 2 on which the tube 9 is fixed is rounded. The end of the tube 9 has a flared part 16 and a chamfer 17.
L'évasement 16 du tube 9 sera réalisé à l'aide d'un outillage approprié, par exemple un mandrin ayant la forme souhaitée et sur lequel le tube sera appliqué avec un effort de compression suffisant permettant la déformation plastique du tube. L'évasement pourra être réalisé éventuellement directement sur le corps 2 de la grenade.The flaring 16 of the tube 9 will be carried out using an appropriate tool, for example a mandrel having the desired shape and on which the tube will be applied with a sufficient compression force allowing the plastic deformation of the tube. The flaring may possibly be carried out directly on the body 2 of the grenade.
Suivant un mode de réalisation avantageux la soudure entre le tube 9 et le corps 2 sera une soudure laser réalisée suivant une couronne circulaire et avec un orientation R du rayonnement telle que celui ci coupe l'extrémité du tube 9 de façon à réaliser à la fois la soudure et le chanfrein d'extrémité 17. Le chanfrein permet d'éviter les surépaisseurs à angles vifs sur le corps qui risqueraient de provoquer un arrachement du tube 9 lors de la dispersion des grenades hors de leur porteur (obus ou roquette) .According to an advantageous embodiment, the weld between the tube 9 and the body 2 will be a laser weld produced according to a circular crown and with an orientation R of the radiation such that it cuts the end of the tube 9 so as to produce both the weld and the end chamfer 17. The chamfer makes it possible to avoid excess thickness at sharp angles on the body which would risk causing the tube 9 to be torn off when the grenades are dispersed out of their carrier (shell or rocket).
Suivant une variante de réalisation (figure 5a) , la paroi externe du corps 2 de grenade comporte un épaulement 18 qui constitue une butée permettant un positionnement axial du tube 9. La fixation du tube sur le corps sera par exemple réalisée par une soudure laser réalisée suivant une couronne circulaire et avec une orientation R sensiblement perpendiculaire au tube et à la paroi externe du corps 2 de grenade.According to an alternative embodiment (FIG. 5a), the external wall of the grenade body 2 has a shoulder 18 which constitutes a stop allowing axial positioning of the tube 9. The tube is fixed to the body for example by laser welding. along a circular crown and with an orientation R substantially perpendicular to the tube and to the external wall of the body 2 of the grenade.
Après fixation du tube 9 sur le corps de grenade, on positionne le système d'amorçage 5 à l'intérieur du tube 9 et on sertit le rebord supérieur 11 sur le système d'amorçage 5.After fixing the tube 9 to the grenade body, the priming system 5 is positioned inside the tube 9 and the upper flange 11 is crimped onto the priming system 5.
La figure 4 résume les différentes étapes du procédé selon l'invention permettant la fixation d'un système d'amorçage sur un corps d'une grenade.Figure 4 summarizes the different steps of the method according to the invention allowing the attachment of a priming system on a body of a grenade.
Au cours d'une première étape A on découpe une portion 9 d'un tube métallique, par exemple en acier de 1 mm d' épaisseur.During a first step A, a portion 9 is cut from a metal tube, for example made of steel 1 mm thick.
A l'étape B, on coiffe avec cette portion de tube 9 une partie d'une surface externe d'un corps 2 de grenade et on fixe par soudure R la portion de tube 9 au corps 2 de la grenade. La soudure sera de préférence une soudure par laser.In step B, this portion of tube 9 is capped with part of an external surface of a body 2 of the grenade and the portion of tube 9 is fixed by welding R to the body 2 of the grenade. The welding will preferably be a laser welding.
Bien entendu, suivant les formes externes du corps 2 de la grenade, on procédera éventuellement à un évasement de l'extrémité du tube, comme décrit précédemment en référence à la figure 5b. Cet évasement sera réalisé entre l'étape A et l'étape B ou directement sur le corps 2 de la grenade.Of course, according to the external shapes of the body 2 of the grenade, one will possibly proceed to a widening of the end of the tube, as described previously with reference to FIG. 5b. This flaring will be carried out between stage A and stage B or directly on the body 2 of the grenade.
A l'étape C on dispose le système d'amorçage 5 à l'intérieur du tube 9.In step C, the priming system 5 is placed inside the tube 9.
Enfin on sertit à l'étape D le tube 9 sur le système d'amorçage 5. Suivant les contraintes de fabrication on pourra donner au tube 9 sa longueur définitive dès l'étape A ou bien procéder à une découpe du tube à sa longueur finale après sa soudure sur le corps (étape B) .Finally, in tube D, the tube 9 is crimped onto the priming system 5. Depending on the manufacturing constraints, the tube 9 may be given its final length from step A or else the tube may be cut to its final length after it has been welded to the body (step B).
Suivant un autre procédé de fixation proposé par l'invention, on pourra après l'étape A passer à une étape E au cours de laquelle on réalisera une collerette formant butée de sertissage 11 à une extrémité du tube 9. Cette collerette pourra être réalisée comme représenté ici après avoir disposé le tube autour du système d'amorçage 5.According to another fixing method proposed by the invention, it will be possible after step A to go to a step E during which a collar forming a crimping stop 11 will be produced at one end of the tube 9. This collar may be produced as shown here after placing the tube around the priming system 5.
Dans ce cas on prévoira un outillage support 19 qui comprendra une partie cylindrique recevant le tube 9 et ayant une hauteur correspondant à celle de la partie du corps de grenade qui recevra ultérieurement le tube 9.In this case, a support tool 19 will be provided which will include a cylindrical part receiving the tube 9 and having a height corresponding to that of the part of the grenade body which will subsequently receive the tube 9.
Il est possible alors de réaliser la collerette de sertissage 11 directement sur le système d'amorçage 5.It is then possible to produce the crimping collar 11 directly on the priming system 5.
A titre de variante on pourra réaliser cette collerette 11 à l'aide d'un outillage approprié distinct du système d'amorçage.As a variant, this flange 11 can be produced using an appropriate tool separate from the priming system.
A l'étape F on coiffe une partie d'une surface externe du corps 2 de grenade avec le tube 9 portant le système d'amorçage 5 et on fixe par soudure R la portion de tube 9 au corps 2 de grenade. La soudure sera là encore une soudure laser.In step F, a part of an external surface of the grenade body 2 is capped with the tube 9 carrying the priming system 5 and the portion of tube 9 is fixed by welding R to the grenade body 2. The welding will again be a laser welding.
Les procédés proposés par l'invention peuvent être mis en oeuvre pour fabriquer des grenades neuves.The methods proposed by the invention can be used to manufacture new grenades.
Ils peuvent avantageusement être utilisés pour fixer à des corps de grenade anciens, déjà chargés d'explosif, un nouveau système d'amorçage plus performant (par exemple doté d'un système d' autodestruction) .They can advantageously be used to attach to old grenade bodies, already loaded with explosive, a new, more efficient priming system (for example provided with a self-destruction system).
Dans ce cas on préparera les corps 2 de grenades en désolidarisant de ces derniers l'ancien système d'amorçage, par exemple par découpe des rivets de fixation. On procède ensuite à la fixation du nouveau système d'amorçage en mettant en oeuvre l'un ou l'autre des procédés selon l'invention. In this case, the bodies 2 of grenades will be prepared by separating from them the old priming system, for example by cutting the fixing rivets. The next step is to fix the new priming system using one or other of the methods according to the invention.
