Definitions

  • An explosive is usually stored in a very stable container.
  • This container usually includes the actual, according to the amount of the explosive material sized container and a releasably attachable to the container closure member over which the container is firmly closed.
  • the explosive is dammed in the container.
  • a container in the sense of the invention is to understand any container in which an explosive is stored, so both packaging and transport containers, and ammunition, ie bullets, which naturally contain an explosive.
  • Such a projectile usually consists of a container body forming the projectile and an ignition containing, the closure member forming igniter, which are firmly bolted together.
  • the closure member forming igniter, which are firmly bolted together.
  • the igniter can be completely separated from the projectile body under internal pressure load before a detonation occurs.
  • these mechanisms often fail to ensure the desired degree of insensitivity.
  • the invention is therefore based on the problem to provide a container for storing an explosive, which is improved in contrast.
  • a container of the type mentioned that the container and the closure member via a connecting member consisting of two by means of a fusible bonding compound whose melting temperature is in the range between 80 ° C to 170 ° C, connected component halves , are interconnected.
  • the container and the closing component are coupled via a specifically designed connecting component which has a safety fuse.
  • the connecting component comprises two components, which are firmly connected to one another by means of a fusible connecting substance, so that the connecting component forms a solid, stable unit at the usual ambient temperature.
  • the melting point of the compound according to the invention is in the range between 80 ° C to 170 ° C, preferably between 100 ° C to 150 ° C.
  • the melting temperature range of 80 ° C to 170 ° C, in particular from 100 ° C to 150 ° C is selected taking into account on the one hand high ambient temperatures, on the other hand of conventional reaction or reaction temperatures used explosives.
  • the ambient temperature or the temperature, which is exposed to a projectile usually well below the lower melting temperature of 80 ° C or preferably 100 ° C.
  • the reaction or reaction temperature of the explosives is above 170 ° C., ie the upper melting temperature limit which, as described, is preferably 150 ° C. If, in the case of a fire, an increase in temperature occurs in the container, for example the projectile, and the temperature rises above the melting temperature of the connecting substance, ie the fuse, the connecting material melts and the formerly firm connection of the connecting component halves is no longer present. Due to pressure, the container now inevitably opens by the connecting component falling apart.
  • the connecting material is preferably a solder, ie a metal alloy, with which the two metal component halves are soldered.
  • a usable solder having a melting point in the specified melting temperature interval of 80 ° C to 170 ° C, preferably from 100 ° C to 150 ° C is, for example Sn42Bi58.
  • the melting point of this SnBi alloy solder is about 138 ° C, ie at a temperature that is neither reached by the usual ambient temperature, nor in the vicinity of the reaction temperature of an explosive. Instead of a solder, a fusible adhesive would be conceivable.
  • the container and the closure member itself are preferably rotationally symmetrical parts, wherein the connecting member is designed in this case as a connecting ring.
  • the formation of the corresponding elements as rotationally symmetrical parts makes their manufacture and assembly particularly simple.
  • Such a rotationally symmetrical container is particularly preferably embodied as a projectile, comprising a projectile body forming the container and an igniter containing the closing component forming igniter, which are connected to one another via the connecting ring.
  • the bullet can be of any kind, d. h., it may contain a head igniter or a bottom detonator, etc.
  • the connecting ring preferably consists of two halves of the ring forming the component halves, which engage axially and are connected to one another via the connecting material.
  • D. h. That the one half of the ring radially overlaps the other half of the ring outside.
  • the respective diameters are, of course, matched to one another, so that there is a largely play-free overgrip.
  • a stop edge is expediently provided on the inner circumference of the one half of the ring and on the outer circumference of the other half of the ring, wherein the stop edges abut each other when telescoping and limit the Einschiebeddling.
  • the assembly of the ring halves is simple on the one hand, on the other hand, the two ring halves are fixed to each other at edge stop, so that the connecting material, so preferably the solder, can be readily applied for connecting the ring halves.
  • the connecting material so preferably the solder
  • the front side of the connecting ring a limiting of both ring halves groove in which the compound is added.
  • this groove which is preferably V-shaped in cross section, a sufficiently large volume is created, in which the bonding material, so preferably the solder, can be introduced. Since the groove of both halves of the ring is limited, the compound wets both ring halves surfaces so that they are fixed. This also a sufficiently large wetting surface is realized, especially if the groove is V-shaped.
  • end-side threaded sections are provided on the two ring halves, which are screwed into corresponding threaded sections on the container and on the closing component. So it is a simple screw realized. It does not matter whether the connecting ring is first screwed to the container, so for example the projectile body, and then the closure member, so for example the igniter is screwed into the connecting ring, or vice versa.
  • Fig. 1 shows in the form of a schematic diagram of an inventive container 1 in the form of a projectile 2, comprising a designed as a hollow cylindrical, rotationally symmetric component projectile body 3, in which the explosive 4 is added.
  • a female threaded portion 5 is provided, in which a connecting ring 6, which has an external thread 7, is screwed.
  • the connecting ring 6 furthermore has an internal thread 8 provided on the other ring end.
  • an igniter 9 which usually has a non-illustrated ignition device in a chamber 10, with an external thread 11 is screwed.
  • the threaded portions 7 and 8 of the connecting ring 6 are in the FIGS. 2 and 3 to see in which the connecting ring 6 is shown in more detail.
  • the explosive 4 is ignited if necessary.
  • the connecting ring 6 consists of two ring halves 12 and 13, which engage with each other, wherein the ring half 12, the outer part and the ring half 13 is the inner part.
  • each stop edges 14, 15 are provided, which are formed via corresponding stages.
  • the insertion movement of the ring half 13 is limited in the ring half 12, so that a defined positioning of both ring halves is given to each other in an excellent end position.
  • the two ring halves 12, 13 are the same length when viewed axially, so that virtually a two-walled connecting ring 6 results.
  • the respective inner and outer diameters are coordinated accordingly, so that there is a largely play-free or minimal play having plug connection.
  • a running on the connecting ring 6 front-side groove 16 see Fig. 3 , in cross-section is V-shaped.
  • the groove 16 is bounded by two ring halves 12, 13 via corresponding groove surfaces 17, 18.
  • a fusible link 19 here taken in the form of a solder 20, that is, that the groove 16 is completely filled with the solder 20.
  • the solder is preferably a SnBi alloy, preferably Sn42Bi58. It is melted introduced into the groove 16 so that it the groove surfaces 17, 18 of this case if necessary also heated metal ring halves 12, 13 completely wetted. After curing of the solder 20, the ring halves 12, 13 are firmly connected.
  • the solder 20 has a melting point, which is preferably in the range between 100 ° C to 150 ° C. So if a temperature in the range of the solder is given, which is in this temperature range, the solder liquefies and the cohesive connection of the ring halves 12, 13 is released.
  • the melting point of the solder Sn42Bi58 is approx. 138 ° C. It is thus within the specified temperature interval and on the one hand significantly higher than the maximum possible ambient temperatures to which a projectile is exposed in use. But it is also significantly lower than the reaction or reaction temperature of the explosive 4 used.
  • the igniter 9 is thus loose on the projectile body 3. As a result, the explosive 4 is no longer dammed. If, due to the temperature, an outgassing of the explosive 4 occurs, then the igniter 9 can be moved slightly out of the projectile body 3 even at a minimal internal pressure, ie. h., That the inner ring half 13 moves slightly from the outer ring half 12, so that there is a narrow vent gap through which the low pressure is reduced. Upon further heating of the explosive, it can readily flow out of the projectile body 3 and burn off, a detonation under rupture of the projectile is thus excluded.
  • Fig. 4 shows an example of the projectile Fig. 1 after melting of the solder 20, wherein for reasons of clarity of the igniter 9 is relatively far out of the projectile body 3 moved out. It is apparent, however, in any case, that the two ring halves 12, 13 are no longer cohesively connected to each other, but are solved due to the melting of the solder 20, so that the igniter 9 together with screwed ring half 13 away from the projectile body 3 together with screwed ring half 12 has been.
