RU2246094C2 - Method for automatic cropping of fixed rounds - Google Patents

Abstract

FIELD: salvaging ammunition.

SUBSTANCE: the method consists in successive loading of cartridges, extraction of the bullet from the cartridge case, pouring out of powder from the cartridge case, pinning out of the primer cap, removal of the cartridge case. The novelty is in the fact that all operations in cropping of rounds are performed at their motion in the trajectory of the cone generating line so that loading is carried out in the section close to the horizontal position of the round, powder is poured out from the cartridge case in the section close to the vertical position of the cartridge case, and the primer cap is pinned out in an inclined position of the cartridge case after pouring out of powder. To enhance the explosion-fire safety at salvaging of rounds, power is sprinkled with water.

EFFECT: simplified procedure and enhanced safety.

Description

The invention relates to the field of disposal of ammunition, in particular to methods for cutting unitary cartridges of small arms into components: bullet, gunpowder, sleeve.

A known method of automated cutting of cartridges (see patent No. 2122706, class F 42 B 33/06, publ. 11/27/98, adopted for the prototype and consisting in the fact that when performing cutting operations (loading cartridges, removing bullets, rash of gunpowder from the sleeve, pricking of the capsule, removal of the sleeve, etc.) the movement of the cartridges is carried out along the cylinder generatrix (in the drum sockets) with the bullet down.

The disadvantage of this method is the difficulty of performing certain operations, namely:

- loading requires a feed mechanism to move the cartridge in the lateral (horizontal) direction;

- orientation of the cartridges when feeding with support on the bullet is not always possible due to the presence of sensitive fuses;

- the pruning of the sleeve of the sleeve is complicated by the same direction (down) of the rash of powder and the ejection of flame from the sleeve when the capsule is ignited.

The present invention solves the problem of creating a high-performance technology for the disposal of cartridges of various calibers.

The technical result obtained from the invention is to simplify the method of cutting cartridges and increase the safety of work when using it.

The specified technical result is achieved in that in a method for automated cutting of unitary cartridges by sequentially performing operations on loading cartridges, removing a bullet from a cartridge case, pouring gunpowder out of the cartridge case, pricking the capsule, removing the cartridge case, it is new that when cutting, the orientation of each cartridge along the axis and their movement is carried out along the trajectory of the generatrix of the cone in such a way that loading is carried out in the area close to the horizontal position of the cartridge, powder is spilled from the sleeve in the area , close to the vertical position of the cartridge case, and the pricking of the capsule - with the inclined position of the cartridge case after the powder is spilled.

To increase the explosion and fire protection of the work when cutting cartridges, irrigation (wetting) of gunpowder is carried out with water.

Distinctive features of the claimed invention is that all operations for cutting unitary cartridges (loading cartridges, removing a bullet from a cartridge case, tipping the capsule, etc.) are performed when they move along the path of the generatrix of the cone, which ensures an optimal position in the space of the cartridge being disassembled at different stages of cutting . This reduces the number of mechanisms that ensure the spatial position of the disassembled cartridge, for example, the feeding mechanism for moving the cartridge in the lateral (horizontal) direction can be excluded. In addition, the safety of work is increased, as with the described method, the direction of the precipitation of gunpowder and the direction of the ejection of flame from the liner during ignition of the capsule do not match.

Based on the foregoing, we can conclude that the proposed technical solution has novelty and inventive step.

The invention is illustrated by drawings, where figure 1 shows a diagram of a device for implementing the proposed method for automated cutting of unitary cartridges of small arms; figure 2 is a sequence diagram of the operation of the device.

The device comprises a cone-shaped multiposition drum 1, on which are placed the lodgements 2 of the cartridge; carriages 3 with grippers 4 and rollers 5; trigger 6 with stops 7; gear 8.

The drum 1 is mounted rotatably on the axis 9.

To fix the cartridges in the drum 1, it is covered by a ring 10.

The device is equipped with a copier 11 for controlling the triggers 6 (cocking, holding, descent).

The management of the carriages 3 is made by a copy groove 12, made on the copier 13, which is placed motionless on the axis 9.

The basis for the device and the protective housing for the service personnel is table 14, which also houses:

- separator 15 (separator of bullets and gunpowder);

- reflector 16 bullets;

- nozzles 37 for supplying water;

- cartridge 18 for cartridges;

- engine and transmission 19 to drive the device;

- sleeve puller 20.

Other elements of the device are not shown as unprincipled.

The proposed method is implemented as follows.

Disposable cartridges 21 on the cartridge 18 are fed (including under the influence of their own weight) in the rotating drum 1, where they are fixed in the lodgment 2 ring 10.

The carriages 3, interacting with the rollers 5 with the copy groove 12, move to the cartridge 21 and vice versa and use the gripper 4 to extract the bullet 22 from the sleeve 23. The gripper 4 is not described as unprincipled.

From the sleeve 23, the powder is poured onto the separator 15 and removed from the table 14. The powder is poured out in the position of the sleeve 23 close to vertical (the most convenient for pouring powder).

The extracted bullet 22 is knocked out of the capture 4 by the reflector 16 and is removed using the separator 15 from the table 14.

The sleeve 23, moving with the rotation of the drum 1 in horizontal and vertical directions, turns away from the spilled powder, where the capsule is pricked with the trigger 6.

With further rotation of the drum 1, the trigger 6 at the stop 7 is removed by the copier 11 from the capsule of the sleeve 23, the sleeve 23 with the sleeve puller 20 is removed from the lodgement 2 and removed outside the device.

All operations for cutting the cartridge occur when it moves along the trajectory of the generatrix of the cone, which ensures the convenience of their carrying out (loading, pouring out powder, tipping the capsule, etc.), simplifies the design of the device and increases the safety of work.

To prevent the possibility of ignition of the powder, it is sufficiently wetted with water.

The device can also be equipped with a cartridge counter, a water supply sensor, fuses against bullet non-extraction, mechanical overload, etc.

The method of cutting cartridges was tested on prototypes when disposing of 12.7 mm and 14.5 mm cartridges and showed reliability, ease of implementation and the possibility of creating high-performance equipment for the disposal of cartridges of various calibers.
