Description

The invention relates to the field of devices for testing weapons, specifically to devices for trapping small arms bullets in the preparation of bulletproof cartridges.

Known bullet trap [1], containing a cylindrical body filled with a medium that absorbs the kinetic energy of the bullet, made of separate sections with a bullet-reflecting screen of fibrous material with a damping pad, and the inner part of the body is filled with fibrous material.

The disadvantages of this bullet is a long period of time and the difficulty of determining the location of the bullet in the fibrous material, the elimination of the bullet channel and the subsequent assembly of the sections.

Closest to the claimed technical solution is the protector selected as a prototype [2], which is a container filled with water to absorb the kinetic energy of the bullet, the hole in the container is tightly closed by the material being pierced by the bullet.

The disadvantages of this bullet trap are the phenomenon of water hammer and the difficult extraction of the bullet.

An object of the invention is the creation of a technologically advanced, effective sample of a bullet catcher having high operational qualities, with the possibility of trapping bullets without deformation for compiling bulletproof cartridges.

The essence of the invention lies in the fact that the bullet catcher containing a cylindrical body filled with water absorbing the kinetic energy of the bullet is installed at an angle of 20 ... 30 ° to the floor, the body is covered with rubber from the inside, there are a number of holes on the upper flange and a cylindrical damper with radially located holes, which reduces the phenomenon of water hammer, provides a guaranteed hit of a bullet in the basket-ball collector, which reduces the time for its removal.

The drawing shows a General view of the bullet trap.

The bullet collector consists of a hollow cylindrical body 1, covered with rubber inside, half filled with water 2 and inclined mounted on the movable frame 3. The ends of the body 1 are closed by lower 4 and upper 5 flanges with gaskets and pulled together by threaded rods 6. A cylindrical damper passes through the bore of the upper flange 5 7, the central hole of which is closed by a removable plug 8 made of easily penetrated material, there are also a number of holes 16 on the upper flange 5. An airtight chute 9 is welded to the lower flange 4. on the bullet trap 10, in the lower part of the chute 9 there is a crane 11. Inside the housing 1 there is a scraper with a handle 12. On the upper part of the movable frame 3 there is a device for fixing arms 13 with an electric trigger 14 and a sleeve case 15, the inner surface of which is covered with rubber.

Bullet collector works as follows.

Set the tested weapon in the device 13, with the help of the electric trigger 14, one or more shots are remotely fired. The shot is made along the axial line of the bullet catcher. When fired, the bullet passes through the central hole of the absorber 7, closed by a removable plug 8 of easily penetrable material, while the kinetic energy of the bullet is absorbed by the liquid 2, and the angle of entry of the bullet into the liquid 2 allows you to reduce the phenomenon of water hammer and save the "pattern" on the surface of the bullet necessary drawing up a bulletproof library. After the shot, the powder gases exit the bullet-proof case 1 through the openings 16 in the upper flange 5. The bullet, having lost its initial velocity in the liquid 2, falls under its own weight into the lower part of the bullet-catcher and gets through the curly bore in the lower flange 4 into the bullet-basket 10. After of which the bullet basket 10 is removed from the groove 9 of the lower flange 4. If for some reason the bullet does not slide into the bullet basket 10, then it is possible to send it using a scraper 12, the handle of which is brought out through the hole in the upper flange 5. If a bullet gets under the bullet basket 10, it is possible to remove it from the housing 1 through the crane 11 in the lower part of the groove. Sleeves after shots fall into the sleeve 15, and the presence of a removable plug in the cylindrical damper 7 also protects the barrel from possible splashes of liquid.

As a result of the invention, a technologically advanced, efficient sample of a bullet catcher was created, which has high performance characteristics that make it possible to reduce the phenomenon of water hammer, which is important when compiling bullet-proof guns, reduce the time and facilitate the delivery of a bullet from the housing, and also select the optimal geometric parameters of the bullet catcher components and parts and the optimal configuration the latter, allowing to simplify the manufacture, operation and repair of the product as a whole.
