Abstract

The invention relates to a method for assembling components constituting a body by implementation of grooving leading to a connection akin to a weld.

Description

La présente invention concerne des corps, de forme adaptée à chacune des applications auxquelles ils s'adressent, qui ont la particularité d'être constitués de pièces dont la fragmentation recherchée pour leurs applications, est obtenue par un procédé "thermique", celui-ci ayant l'avantage de réaliser en même temps la liaison mécanique d'un certain nombre de ces pièces pour confectionner le corps. A titre d'exemple et de façon non limitative, de tels corps peuvent être utilisés comme charge militaire opérationnelle pour des munitions de type grenade. The present invention relates to bodies, of shape adapted to each of the applications to which they are addressed, which have the particularity of being made up of parts whose fragmentation sought for their applications, is obtained by a "thermal" process, the latter having the advantage of realizing at the same time the mechanical connection of a certain number of these parts to make up the body. By way of example and without limitation, such bodies can be used as an operational military charge for grenade-type ammunition.

Actuellement et à titre d'exemple, les charges militaires opérationnelles pour des munitions de type grenade sont réalisées:
- soit de façon monobloc dans lesquelles on insère l'explosif,
- soit par un matériau roulé comme un ressort à spires jointives dans lequel on insert l'explosif,
- soit par empilage de rondelles non reliées entre elles mécaniquement chemisant l'explosif et maintenues par ce dernier.Currently and by way of example, operational military charges for grenade-type ammunition are carried out:
- either in one piece in which the explosive is inserted,
- either by a rolled material such as a spring with contiguous turns in which the explosive is inserted,
- Either by stacking discs which are not mechanically linked together lining the explosive and maintained by the latter.

L'invention porte sur la réalisation de charges constituées de pièces reliées entre elles, grâce à une liaison qui s'apparente à une soudure découlant du rainurage de fragmentation réalisé par un "procédé thermique", comme celui qu'offre, à titre d'exemple, un procédé laser. The invention relates to the production of loads made up of parts linked together, by means of a connection which is similar to a weld resulting from the grooving of fragmentation carried out by a "thermal process", such as that offered by way of example, a laser process.

L'invention a donc pour objet, une pièce mécanique constituée d'éléments conduisant à une structure monolithique obtenue par une liaison pièce à pièce générée par l'usinage de rainures faites par un procédé thermique, et elle est caractérisée selon une première variante - FIGURE 1 - par un corps (1) constitué de pièces (2) distinctes étant accolées ou proches les unes des autres, - FIGURE 1 & FIGURE 2 - par au moins une rainure (3), commune à au moins deux pièces contigues, - FIGURE 1 - par la liaison (4), d'au moins deux pièces (2) contigues, obtenue au cours de l'opération de rainurage faite par un procédé thermique. The subject of the invention is therefore, a mechanical part made up of elements leading to a monolithic structure obtained by a part-to-part connection generated by the machining of grooves made by a thermal process, and it is characterized according to a first variant - FIGURE 1 - by a body (1) consisting of separate parts (2) being joined or close to each other, - FIGURE 1 & FIGURE 2 - by at least one groove (3), common to at least two adjoining parts, - FIGURE 1 - by the connection (4), at least two contiguous parts (2), obtained during the grooving operation made by a thermal process.

Selon une deuxième variante, la forme extérieure des pièces (2) FIGURE 1 peut être de forme quelconque. According to a second variant, the external shape of the parts (2) FIGURE 1 can be of any shape.

Selon une troisième variante, le profil d'une rainure peut être de forme quelconque. According to a third variant, the profile of a groove can be of any shape.

Selon une quatrième variante, au moins l'une des rainures peut être localisée soit sur une surface extérieure du corps (1), soit sur une surface intérieure du même corps.  According to a fourth variant, at least one of the grooves can be located either on an external surface of the body (1), or on an internal surface of the same body.

Claims (7)
