Description
Fremgangsmåte til fremstilling av splinthylser. Method for the production of cotter sleeves.
Oppfinnelsen vedrører en fremgangsmåte for fremstilling av splinthylser ved anvendelse av prefabrikerte, fortrinnsvis kuleformede splinter. The invention relates to a method for producing cotter sleeves using prefabricated, preferably ball-shaped cotter pins.
Det er allerede kjent å forbehandle sprenglegemer ved langs- og tverrgående innsnitt, slik at de ved detonering av sprengladningen deles opp i adskilte splinter. Det er også kjent å tilveie-bringe denne virkning ved innlegg av en på forhånd utformet folie på sprengstoffoverflaten. Bortsett fra at den.effekt som kreves for opp-deling av slike sprenglegemer vesentlig reduserer splinteffekten, sik-rer de ovennevnte forholdsregler ikke at det dannes splinter av definert størrelse, gjennomslagseffekt og jevn spredning til alle sider. It is already known to pre-treat explosives by longitudinal and transverse incisions, so that when the explosive charge is detonated, they are split into separate splinters. It is also known to provide this effect by placing a preformed foil on the surface of the explosive. Apart from the fact that the power required for breaking up such explosives significantly reduces the splinter effect, the above-mentioned precautions do not ensure that splinters of a defined size, penetration effect and uniform spread to all sides are formed.
En bedre splintvirkning og -fordeling kan oppnås med prefabrikerte splinter som f. eks.-fylles i en form og leires i et herd-ende skjelett av betong, kunststoff eller lignende. Det er aåledes kjent å 'anordne prefabrikerte kulesplinter i ett eller flere lag på A better splinter effect and distribution can be achieved with prefabricated splinters which, for example, are filled in a mold and embedded in a hardening skeleton made of concrete, plastic or the like. It is therefore known to arrange prefabricated ball splinters in one or more layers on
et sprenglegeme. Kulene er derved forbundet med en støpeharpiks eller lignende og danner en mer eller mindre motstandsdyktig splinthylse. an explosive device. The balls are thereby connected with a casting resin or the like and form a more or less splinter-resistant sleeve.
Da denne sammenbakte splinthylse imidlertid bare er istand til å ta opp små aksiale krefter og så å si ingen radiale krefter, er anvend-elsen begrenset til kasteammunisjon og rotasjonsfattige rakettprosjek-tiler. Til bruk for prosjektiler kreves ikke bare et hylseskjelett, men dessuten også en ommantling som er istand til å oppta de opptred-ende .krefter. Dette 'betyr at det dels må medføres ekstra masse som ikke'bidrar til splintvirkningen, dels som ovenfor nevnt, at spreng-ladningens, effekt reduseres. Ved hjelp av prefabrikerte kulesplinter økes riktignok trefftettheten vesentlig hos splintprosjektiler med ekstra innleirede kulesplinter og ommantling, men gjennomslagseffekten reduseres på en uønsket måte. However, since this combined splinter sleeve is only able to take up small axial forces and virtually no radial forces, its use is limited to throw ammunition and low-rotation rocket projectiles. For use with projectiles, not only a sleeve skeleton is required, but also a casing that is able to absorb the acting forces. This means that extra mass must be carried which does not contribute to the splintering effect, and, as mentioned above, that the effect of the explosive charge is reduced. With the help of prefabricated bullet splinters, the hit density of splinter projectiles with extra embedded bullet splinters and sheathing is indeed increased significantly, but the impact effect is reduced in an undesirable way.
Foreliggende oppfinnelse går derfor ut på å utforme prefabrikerte splinter sammen med prosjektil-, resp. stridshodehylsen, slik at det oppstår en splintmantel som riktignok er istand til å overvinne de skyve- og rotasjonskrefter som opptrer ved utskyting, men som av sprengladningen uten større effekttap deles fullstendig opp i splinter av definert størrelse og antall og med stor gjennom-slagsef f ekt og fastsatt spredningsområde. The present invention therefore consists in designing prefabricated splinters together with projectile, resp. the warhead sleeve, so that a shrapnel jacket is created which is indeed able to overcome the thrust and rotation forces that occur during launch, but which is completely broken up by the explosive charge without major loss of effect into shrapnel of a defined size and number and with a high penetration effect and fixed distribution area.
Ifølge oppfinnelsen løses denne oppgave ved at det i en sylindrisk, svakt konisk forløpende, verktø<y>hulform med en indre diameter som svarer til den ytre diameter av splinthylsen som skal fremstilles, innføres et metallisk (prosjektil-) rørlegeme med passende ytre diameter, at det sentrisk i rørlegemet innføres et annet metallisk rørlegeme, hvis ytre diameter er så meget mindre enn den indre diameter av yttermantelrørlegemet at avstanden svarer til den dobbelte maksimale diameter av splintene, at splintfyllingen helles inn i det således dannede rørsylinderhulrom og at det indre rørlegeme i tilslutning ved høytrykkforming under fullstendig omslutning av splintene trykkes radialt'utad-og trykkes sammen med det. ytre rør til en rotasjonssymmetrisk splinthylse med splintmantel anordnet i rørenes grenseområde. According to the invention, this task is solved by introducing a metallic (projectile) tubular body with a suitable outer diameter into a cylindrical, slightly conical, tool hole shape with an inner diameter that corresponds to the outer diameter of the splinter sleeve to be produced, that another metallic tube body is introduced centrally in the tube body, whose outer diameter is so much smaller than the inner diameter of the outer casing tube body that the distance corresponds to twice the maximum diameter of the splinters, that the splinter filling is poured into the pipe cylinder cavity thus formed and that the inner tube body in connection by high-pressure forming under complete enclosing of the splines is pressed radially outwards-and pressed together with it. outer tube to a rotationally symmetrical spline sleeve with a spline jacket arranged in the border area of the tubes.
Derved kan det fremstilles en splintmantel i ett eller flere lag. Til fremstilling av splintlegemer i flere lag settes flere rør, som hvert er smalere enn det utenpåliggende rør, svarende til den dobbelte splintdiameter, sentrisk i hverandre. Rørsylinderhul-rommene fylles med splintlegemer, og rørene trykkes deretter mot hverandre under fullstendig innelukking av splintene, samt under samtidig forhåndsfragmentering av rørene i splintelementer med fastsatt størr-else og masse. Thereby, a splint mantle can be produced in one or more layers. For the production of splinter bodies in several layers, several tubes, each of which is narrower than the overlying tube, corresponding to twice the splinter diameter, are inserted centrally into each other. The tube cylinder cavities are filled with splinter bodies, and the tubes are then pressed against each other under complete containment of the splinters, as well as during simultaneous pre-fragmentation of the tubes into splinter elements of fixed size and mass.
Med fremgangsmåten ifølge oppfinnelsen oppnås splinthylser, som består av to eller flere rør som er presset mot hverandre og er prefragmentert av de innelukkede kulesplinter og omslutter ett eller flere lag av kulesplinter. Disse splinthylser holder stand mot de skyve- og sentrifugalkrefter som oppstår ved rotasjonsprosjektiler under avskytning. Da rørene ved høytrykkformingen blir innsnittsak- With the method according to the invention, splinter sleeves are obtained, which consist of two or more tubes that are pressed against each other and are pre-fragmented by the enclosed ball splinters and enclose one or more layers of ball splinters. These splinter sleeves withstand the thrust and centrifugal forces that occur with rotating projectiles during firing. As the pipes are cut during high-pressure forming
tig prefragmentert av de innpressede kulesplinter av hardt materiale, likesom blir forskjelligartet komprimert og dermed oppdelt i et sammenhengende gitter av splintelementer, oppnås at det ved detonering av sprengladningen ikke bare frigjøres kulesplinter, men at også røre- pre-fragmented by the pressed-in bullet splinters of hard material, as well as being variously compressed and thus divided into a continuous grid of splinter elements, it is achieved that upon detonation of the explosive charge not only are bullet splinters released, but also
ne deles opp i mange, jevne splinter med fastsatt størrelse, som spres over et begrenset område med definert gjennomslagseffekt. are divided into many, even splinters of a fixed size, which are spread over a limited area with a defined penetration effect.

The procedure will be described in more detail below with reference to the drawing. Fig. 1 is a side view of a rotary projectile, partially in section.
