Description
7709768-1 2 Föreliggande uppfinning har som huvudändamål att framskapa en anordning och ett sätt som löser den i ovanstående förespegla-de problematiken. 7709768-1 2 The present invention has for its main object to provide a device and a method which solves it as predicted above the problem.
.Det som huvudsakligen kan anses vara känneteoknande för en anord- åning enligt uppfinningen är att i stridsdelen är införda smala- ímartensitstråk, utefter vilka stridsdelen brister vid sin sönder- asprängning. Ett sätt för att framställa en dylik stridsdel för ernående av förfragmentering av densamma går väsentligen ut på att i stridsdelens material inordnas smala martensitstråk. a Stridsdelen är därvid utformad i företrädesvis seg stâlkvalitet..What can mainly be considered as characteristic of a device according to the invention is that in the combat part narrow ímartensitstråk, along which the combat part fails in its disintegration blasting. A way to produce such a combat part for achieving pre-fragmentation of the same is essentially about that narrow martensite lanes are arranged in the material of the combat part. a The combat part is then designed in preferably tough steel quality.
Genom att martensitfasen är extremt spröd kommer den att spricka före grundmaterialet i stridsdelen när denna sönderspränges av aktuell sprängsats. Genom att martensitfasen är extremt spröd kommer en spricka att kunna utbildas och fortplanta sig innan .sprickbildningen i stridsdelens övriga material uppträder. Sprick- spetsens radie kan hållas mycket liten och materialspänningarna kring sprickan blir förhållandevis stora och ett styrt sprick- förlopp skapas. o En anordning och ett sätt enligt uppfinningen skall beskrivas i É nedanstående under samtidig hänvisning till bifogade ritningar där. figuren i sidovy visar en granat som förses med.martensit-I stråk medelst en värmekälla.Because the martensite phase is extremely brittle, it will crack before the base material in the combat unit when it explodes current blast kit. Because the martensite phase is extremely brittle a crack will be able to form and reproduce before .cracking in the other material of the combat part occurs. Cracked the radius of the tip can be kept very small and the material stresses around the crack will be relatively large and a controlled crack process is created. A device and a method according to the invention will be described in É below with simultaneous reference to the accompanying drawings therein. the figure in side view shows a grenade provided with.martensite-I strokes by means of a heat source.
I figuren är en granat angiven med 1 och en värmekälla i form av. en laser med 2. Granaten kan utgöras av en konventionell sådan som innefattar en sprängkropp och en sprängämnessats som vid sin ini- tiering sönderspränger sprängkroppen; Från lasern utgår en laser- strále 3 som reflekteras av en reflektor 4 mot granatens utsida som bildas av nämnda sprängkropp, vilken skall förfragmenteras i enlighet med uppfinningen. lReflektorn 4 är av i och för sig känt slag som medelst ej speciellt visade organ är vippbart anordnad kring punkten 5. Organen kan där- vid vara anordnade, på likaledes i och för sig känt sätt, att åstadkomma vipprörelser på reflektorn inte bara i figurplanet i de med pilarna 6 angivna riktningarna, utan även i en eller flera 7709768-1 3 riktningar i förhållande till nämnda plan. Projektilen är vrid- bart anordnad kring sin axel medelst likaledes ej speciellt visade organ. Roteringen av projektilen kan ske i den med pilen 8 angivna riktningen, den motsatta riktningen eller båda riktningarnaf Genom ett dylikt arrangemang kan laserstrâlen fås att följa av vippningen på reflektorn 4, roteringen på granaten 1 och/eller in- och urkoppling av värmekällan beroende banor eller stråk 9 på projektilens mantelyta. Dessa stråk kan görasfsammanhängande eller indelas i separata från varandra skilda stråk så att geometrier av önskat utseende ernås. Martensitstråken göres därvid så djupa som möjligt är med ifrågavarande metod.In the figure, a grenade is indicated by 1 and a heat source in the form of. a laser with 2. The grenade can be a conventional one such as comprises an explosive body and an explosive kit which at its ini- tiering explodes the explosive body; The laser emits a laser beam 3 which is reflected by a reflector 4 towards the outside of the grenade which is formed by said explosive body, which is to be pre-fragmented in in accordance with the invention. The reflector 4 is of a kind known per se which by means of no special The means shown are pivotally arranged around point 5. The means can then in the case of being arranged, in a manner known per se, that cause tilting movements on the reflector not only in the figure plane in the directions indicated by the arrows 6, but also in one or more 7709768-1 3 directions in relation to said plane. The projectile is rotatable arranged around its axis by means of likewise not specifically shown organ. The projectile can be rotated in the direction indicated by the arrow 8 the direction, the opposite direction or both directionsf Through such an arrangement, the laser beam can be made to follow the tilting of the reflector 4, the rotation of the grenade 1 and / or and disconnecting the heat source depending on paths or lanes 9 on projectile mantle surface. These lines can be made coherent or divided into separate stripes so that geometries of the desired appearance is achieved. The martensite strips are made so deep as possible with the method in question.
Nämnda stråk 9 kan anses bestå av ett antal punkter, av vilka en i figuren är angiven med 10. Laserstrålen upphettar materialet lokalt i respektive punkt till en temperatur som för det valda ståJ.materialet motsvarar martensittemperaturen. När strålen flyttas till nästa punkt i aktuellt stråk svalnar materialet i den förut uppvärmda punkten eller zonen snabbt på grund av att punktens eller zonens area är förhållandevis liten så att det punkten eller zonen omgivande materialet i sprängkroppen mycket snabbt kan absorbera värmet från punkten eller zonen. Härigenom erhålles en snabb härdning som gör att martensitfasen urskiljes och bibehålles. Genom att martensiten har lägre täthet än grund- materialet byggs tryokspänningar in i ytan, vilket i hög grad motverkar statisk sprickbildning. å Genom utnyttjandet av en laser såsom värmekälla kan man med det visade arrangemanget i princip välja det av stråken bildade mönstret godtyckligt samtidigt som arbetet kan utföras i luft.Said path 9 can be considered to consist of a number of points, one of which in the figure is indicated by 10. The laser beam heats the material locally at each point to a temperature as for the selected the standing material corresponds to the martensite temperature. When the beam moved to the next point in the current path, the material cools in the pre-heated point or zone quickly due to the area of the point or zone is relatively small so that the point or zone surrounding the material in the explosive body a lot can quickly absorb heat from the point or zone. Hereby a rapid cure is obtained which makes the martensite phase distinguishable and maintained. Because the martensite has a lower density than the basic the material builds compressive stresses into the surface, which to a large extent counteracts static cracking. å By using a laser as a heat source, you can do it showed the arrangement in principle choose the one formed by the strings the pattern arbitrarily while the work can be performed in air.
Det är aeek även möjligt ett aeteakemme merteneitetraken- medelst elektronstråle, varvid arbetet företrädesvis utföres i vakuum så att en tillräckligt sammanhållen elektronstråle kan erhållas för bildande av ett smalt stråk.It is aeek also possible a aeteakemme merteneitetraken- by means of electron beam, the work being preferably performed in vacuum so that a sufficiently coherent electron beam can be obtained to form a narrow lane.
I en utföringsform av ett sätt enligt uppfinningen utskiljes martensitfasen i respektive punkt av nämnda stråk genom upphett~ ning av materialet i punkten till aktuell temperatur medelst en Homes-ir längs stråken riktbar värmekälla eller reflektor och genom en härdning som.kommer till stånd efter värmekällans förflyttning från berörd punkt medelst snabb värmeavledníng i det punkten omr ïgivande materialet. íI figuren har med 11 angivits ett utrymme, i vilket inläggningen av martensitstråken utföres. Nämnda utrymme förutsättes stå under vakuum i fallet med elektronstrålkälla..In one embodiment of a method according to the invention is separated the martensite phase at each point of said strip by heating ~ the material at the point to the current temperature by means of a Homes-ir along the lanes directable heat source or reflector and through a hardening that occurs after the heat source has moved from the point concerned by means of rapid heat dissipation at the point omr ïgivende materialet. In the figure, 11 indicates a space in which the insert of the martensite lanes is performed. The said space is assumed to be below vacuum in the case of electron beam source ..
Uppfinningen är inte begränsad till den i ovanstående såsom exempel visade utföringsformen utan kan underkastas modifikationer inom ramen för efterföljande patentkrav.The invention is not limited to that of the above by way of example shown embodiment but may be subjected to modifications within the scope of the appended claims.
