【発明の詳細な説明】 演習弾の自己破壊式発射体ヘッド 本発明は請求項１の前提部に記載の演習弾の自己破壊式発射体ヘッドに関するも のである。[Detailed description of the invention] Self-destructive projectile head for training ammunition The present invention also relates to a self-destructive projectile head of a practice ammunition according to the preamble of claim 1. It is.
ドイツ国特許第３６４２４１４号に記載の無反動砲用の演習弾の自己破壊式発射 体ヘッドは、圧縮金属粉末または焼結金属粉末によって作られたコア（芯）と、 金属またはプラスチック等で作られた上記コアを取り囲んでいる先端衝撃区域が 平坦な円錐形フード形とによって構成されている。Self-destructive firing of training ammunition for recoilless rifles as described in German Patent No. 3642414 The body head has a core made of compressed metal powder or sintered metal powder, A tip impact area surrounding the core made of metal or plastic etc. It consists of a flat conical hood shape.
この自己破壊ヘッドを有する演習弾が標的、一般には鉄板に当たると、フードが 破裂し、衝撃力によってコアがほぼ粉末の形まで破壊される。すなわち、標的に 当たった演習弾の自己破壊式発射体のエネルギーの最大の部分は上記コアの破壊 によって消費される。このコアの破壊によって標的が過度に損傷することが防止 されるとともに、演習弾の自己破壊式発射体が標的から跳ね返って、演習場にい る人間が負傷するという危険性が防止される。When a practice bullet with this self-destructing head hits a target, typically a steel plate, the hood will explode. It ruptures and the impact force destroys the core to almost powder form. i.e. to the target The largest part of the energy of the self-destructing projectile of the practice bullet that hits is the destruction of the core mentioned above. consumed by. Destruction of this core prevents excessive damage to the target. At the same time, the self-destructing projectile of the training munitions bounces off the target and enters the training range. The risk of injury to persons involved is prevented.
ドイツ国特許第２７５７６６６号に記載の演習弾の自己破壊式発射体のコアは脆 性のある材料で作られ且つ貫通孔を有しており、この貫通孔の中にはクサビが挿 入されている。このクサビは、発射体が標的に当たった時に、貫通孔中に押し込 まれてコアを破壊するようになっている。この発射体はクサビがコアを割るよう になっているので、」二記の自己破壊式発射体よりも標的に当たった際の破壊状 態が良くなる。しかし、この方法は最適なものではない。The core of the self-destructing projectile of the practice munitions described in German Patent No. 2757666 is fragile. It is made of a flexible material and has a through hole into which a wedge can be inserted. is included. This wedge is pushed into the hole when the projectile hits the target. It is designed to destroy the core. This projectile has a wedge that breaks the core. Therefore, the state of destruction when hitting the target is lower than that of the self-destructive projectile described in 2. Your condition will improve. However, this method is not optimal.
これら公知の自己破壊式発射体ヘッドは、破壊ヘッドが標的に角度を成して当た った時には確実に破壊しない場合があるということが知られている。こうした斜 め衝突は、演習弾の自己破壊式発射体の飛行方向が標的と一定の角度を成してい た場合だけでなく、発射体が真っ直ぐに発射された場合にも起こる。These known self-destructing projectile heads are designed so that the destructuring head hits the target at an angle. It is known that there are cases in which destruction does not occur reliably. This slope A collision occurs when the direction of flight of the self-destructing projectile of a practice munitions is at a certain angle with the target. This occurs not only when the projectile is fired straight, but also when the projectile is fired straight.
すなわち、重量が軽い演習弾の発射体は射撃方向にふらついているので、標的に 一定の角度を成して当たることがある。In other words, the light weight practice bullet projectile wanders in the firing direction, making it difficult to hit the target. It may hit at a certain angle.
本発明の課題は、単純な対策によって、発射体が万一標的に角度を成して当たっ た場合でも、確実に自己破壊して、跳ね返ることがないようにするこきにある。The problem of the present invention is to prevent the projectile from hitting the target at an angle by simple measures. This is to ensure that it self-destructs and does not bounce back even if it does.
この課題を解決するための本発明の手段は請求項１の特徴部分に記載されている 。The means of the invention for solving this problem are specified in the characterizing part of claim 1. .
すなわち、本発明では、自己破壊式発射体のフードとコアとの間に力伝達体とし て単にボールが挿入されるだけである。この構成はコアの破壊に対して最高の結 果を与える。この破壊結果は、前記のクサビ型力伝達体を用いたものや、コアと 対向した区域が半球形状で、フードと対向した区域がフード内壁に一致したピラ ミッド形状をした力伝達体を用いたものより大幅に優れている。力伝達体として のボールはフード内壁とコアのノツチの上側端縁部と当接し、演習用発射体が標 的に当たった際に、衝撃力が常にボールの中心を通り、全ての衝撃角度に対して ほぼ同じ破壊力が生じるという利点がある。従って、演習用発射体が極端な角度 で標的に当たった場合でも、コアが確実に破壊される。上記の凹部すなわちノツ チは例えば円筒形でもよいが、テーパー付きのノツチが非常に優れた結果を与え る。That is, in the present invention, a force transmitting body is provided between the hood and the core of the self-destructive projectile. The ball is simply inserted. This configuration provides the best results against core failure. give fruit. This fracture result is similar to the one using the wedge-shaped force transmitting body mentioned above or the one using the core. The opposing area is hemispherical, and the area facing the hood is a pillar that matches the inner wall of the hood. This is significantly superior to those using mid-shaped force transmitters. As a force transmitter The ball is in contact with the inner wall of the hood and the upper edge of the notch in the core, and the training projectile is When the ball hits the target, the impact force always passes through the center of the ball and for all impact angles. The advantage is that almost the same destructive force is generated. Therefore, the practice projectile is placed at an extreme angle. Even if it hits the target, the core will definitely be destroyed. The above recess or notch The tip may be cylindrical, for example, but a tapered notch gives very good results. Ru.
力伝達体としてボールを有する本発明の自己破壊式ヘッドの製造は非常に単純で 且つ安価である。ボールは大量失産品であり、コア、ボールおよびフードの組立 ては簡単にできる。The manufacture of the self-destructive head of the invention with balls as force transmitters is very simple. Moreover, it is inexpensive. The ball is a mass-produced product, and the assembly of the core, ball and hood is It's easy to do.
本発明のその他の実施態様は従属項に記載されている。Further embodiments of the invention are described in the dependent claims.
以下、添付図面を参照して本発明の３つの実施例を詳細に説明する。添付図面は 本発明の自己破壊式発射体ヘッドの各縦方向断面図である。Hereinafter, three embodiments of the present invention will be described in detail with reference to the accompanying drawings. The attached drawings are 1 is a longitudinal cross-sectional view of a self-destructing projectile head of the present invention; FIG.
本発明の自己破壊式ヘッド１は、図示していない演習用発射体に取り付けられる 基部２と、この基部２の上に乗っている円筒状のコア３と、上記基部２に結合さ れ且つｔ記コア３を覆っている薄いフード４とを有している。フード４は、上記 コア３を越えた区域がテーパー状になっており、先端５は平坦になっている。こ の自己破壊式ヘッド１の縦軸線Ａはコア３およびフード４の縦方向中心軸線でも ある。The self-destructive head 1 of the present invention is attached to a training projectile (not shown). A base 2, a cylindrical core 3 placed on the base 2, and a cylindrical core 3 connected to the base 2. and a thin hood 4 covering the core 3. Hood 4 is as above The area beyond the core 3 is tapered and the tip 5 is flat. child The longitudinal axis A of the self-destructive head 1 is also the longitudinal center axis of the core 3 and the hood 4. be.
自己破壊式ヘッドＩの上記先端５と向き合うコア３の上側表面には、上記軸線Ａ を中心とした下向きテーパー状の截頭円錐形状のノツチ６が形成されている。こ のノツチ６の内部にはボール７が収容されているが、このボール７は、ボール７ の中心がノツチ６の上側端縁部よりわずかに上方の位置となり且つノツチの上側 端縁部の区域でノツチがボール７とほぼ接線状に接するような状態で収容されて いる。一方、フード４側では、ボール７がフード４の内壁の先端５の区域と上記 のテーパ一部分とに当接している。The upper surface of the core 3 facing the tip 5 of the self-destructive head I has the axis A A truncated cone-shaped notch 6 is formed with a downward taper centered at . child A ball 7 is housed inside the notch 6 of the ball 7. The center of the notch 6 is located slightly above the upper edge of the notch 6, and The notch is accommodated in such a way that it is in approximately tangential contact with the ball 7 in the region of the edge. There is. On the other hand, on the hood 4 side, the ball 7 is connected to the area of the tip 5 of the inner wall of the hood 4 and above. A part of the taper of is in contact with.
ボール７の直径はコアの直径の約２／３であり、ノツチ６の深さはボールの直径 にほぼ対応している。従って、ノツチ底部での直径はコアの直径の約１／３であ る。The diameter of the ball 7 is approximately 2/3 of the diameter of the core, and the depth of the notch 6 is the diameter of the ball. It almost corresponds to Therefore, the diameter at the bottom of the notch is about 1/3 of the core diameter. Ru.
この自己破壊式ヘッド１が標的に当たると、ボール７がノツチ６の内部に押し込 まれる。従って、フード４が破裂した時にはコア３が衝撃力とほぼ同じ力で割ら れ、破壊される。When this self-destructive head 1 hits the target, the ball 7 is pushed into the notch 6. be caught. Therefore, when the hood 4 ruptures, the core 3 will be broken by approximately the same force as the impact force. destroyed.
第２図に示した実施例と第１図の実施例との違いは、ノツチ６′が円筒形である 点のみである。その他の設計も可能である。The difference between the embodiment shown in FIG. 2 and the embodiment shown in FIG. 1 is that the notch 6' is cylindrical. There are only points. Other designs are also possible.
この場合、ボール７の直径はノツチ６°の直径より大きい。In this case, the diameter of the ball 7 is larger than the diameter of the notch 6°.
第３図に示した実施例と第１図の実施例との違いは、ボール７′が複数の部分、 図示した例では２つの半球体ＢおよびＣで構成されており、これらの２つの部分 が例えば接着剤８で互いに弱く接着されている点である。この接着方法を用いる ことによって、自己破壊式ヘッドの組み立て時のボールの取り扱いが容易になる 。この場合には、各半球体が完全球のボールに比べて空気抵抗が高いため、コア ３が破壊した後にボールの半球体が互いに分離した際に、照準盤に当たって跳ね 返る跳ね返りが完全球のボールの場合に比べて小さくなる。２つの半球体の各中 心軸に対する分離用継ぎ目の位置は破壊とは無関係である。The difference between the embodiment shown in FIG. 3 and the embodiment shown in FIG. 1 is that the ball 7' has multiple parts, The illustrated example consists of two hemispheres B and C, and these two parts are weakly bonded to each other with adhesive 8, for example. Use this adhesive method This makes it easier to handle the ball when assembling the self-destructing head. . In this case, each hemisphere has a higher air resistance than a perfect ball, so the core When the hemispheres of the ball separate from each other after 3 is destroyed, it bounces off the aiming board. The bounce back is smaller than that of a perfect ball. Inside each of the two hemispheres The location of the separation seam relative to the mandrel is independent of failure.
第３図では分離用継ぎ目と」１記中心軸との間の角度を約４５°にしである。In FIG. 3, the angle between the separation seam and the central axis marked 1 is approximately 45°.
