  • Patent number: 7637194
    Abstract: The invention relates to the field explosives technology and concerns a method and a device in which the explosive materials are removed from their casings. The object of the solution according to the invention is to disclose a method and a device with which explosives-containing bodies with non-uniform dimensions and also with internal attachments can be safely opened and dismantled. The object is attained through a method in which a strip of casing material is removed up to a residual wall thickness by means of machining tools, subsequently pressure is applied on the casing by means of a pressing tool and then the explosive material is removed from the casing by means of melting or by means of pressing. The object is further attained through a device comprising a device for removing a chip and a device for applying pressure on the explosives-containing bodies and devices for transporting the explosives-containing body.

  • Patent number: 6901835
    Abstract: An extractor and method for safely releasing an explosive and liner from a munition is disclosed. An exemplary extractor includes a support device connected to the casing of the munition and adapted to stabilize the munition as the explosive is released from the dome end of the munition casing and a fluid port adjacent the dome end of the casing and adapted to introduce a high pressure fluid through the dome end to the explosive to separate and release the explosive from the dome end. An exemplary method for releasing an explosive and liner from a dome end of a munition casing includes inserting a fluid port into a dome end of the casing and introducing a fluid through the fluid port to the explosive to release and separate the explosive from the dome end and to shear the mechanical coupling between the liner and the casing.

  • Patent number: 6212986
    Abstract: Provided is an automated case cutting device that may be remotely controlled to rotate and cut an outer case of an object. It can be applied to the disassembly and disposal, testing, or inspection of munitions. In one application, the device cradles a generally cylindrical munition of a length much greater than its diameter on two rollers attached to a bed or plate comprising a support frame. One of the rollers is rotated by a transmission mechanism powered by an electrical motor, while the other roller may also be turned by the same transmission mechanism via a sprocket and chain set. The munition may be further held in place by one or a set of holding rollers attached to a frame hinged to the support frame, so that the holding roller(s) swing onto the top of the munition after the munition is placed on the cradling rollers. The holding roller(s) may also be turned via a second sprocket and chain set, driven off the same drive shaft as the first roller.

  • Patent number: 5974937
    Abstract: A method for removing an explosive charge from a shaped charge munition is disclosed together with a system for carrying out the method. The preferred method for removing a charge from a stackable shaped charge munition, such as a M42 or M46 grenade, involves three punching stages using two hollow punch dies of different diameters and lengths to extract the metal cone-shaped liner and all of the explosive except a layer lining the inner side wall and dome end wall of the casing. The thin layer of explosive can be readily removed in an explosive waste incinerator. The system for carrying out the method includes a delivery conveyor, a rotatable indexing table having multiple gripping devices for holding grenades or other shaped charge munitions, multiple punching stations positioned in sequence around the perimeter of the indexing table, and a take-off conveyor for transporting processed grenades from the indexing table.

  • Patent number: 5714707
    Abstract: Small caliber primed cartridge cases are demilitarized by removing explosive primer mix from the cases. The cases are flushed with a chemical solution, preferably a sulfuric acid solution, to dissolve the binder material which holds the components of the explosive primer mix together. Upon dissolution of the binder material, e.g. gum arabic, the primer mix breaks apart into particles which flow forward through the flash hole(s) in the case and exit the open end of the case. The solution is agitated into a turbulent state so as to enter the open end of the hollow case and sufficiently contact the primer mix through the flash hole(s). The treated cases are chemically deprimed in that the explosive primer mix has been removed therefrom; additionally, any primer mix which might remain in the case is rendered inert by the acid solution. The deprimed cases may then be rinsed and dried and used for reloading applications or scrap recovery.

  • Patent number: 5295428
    Abstract: The present invention relates to a method of disassembling large-caliber combat cartridges, particularly armor-piercing cartridges, including a combustible casing jacket that conically widens in the direction of the projectile, a casing bottom and a casing cover to which is fastened a sub-caliber projectile equipped with a propelling sabot.To be able, on the one hand, to reduce expenditures for the disassembly of such combat cartridges and, on the other hand, to reuse a major portion of the original combat cartridges for the production of corresponding training cartridges, it is proposed to separate the casing jacket as well as the casing cover starting at their outer circumference, in regions having approximately the same, predetermined diameter D1. This diameter D1 here corresponds to the maximum diameter of the component of the new cartridge to be produced later from the disassembled components.

    Abstract: A method and device (A) for cutting a shotgun shell (14) for shooting in a shotgun chambered for shorter shotgun shells includes a base (10) and shell receiving tube (12). A shell (14) is held in tube (12) above a knife (32) in such a manner that a circumferential slit is formed in shell casing (20) around the inside edge (24) of crimp (22). The knife is carried on a movable knife blade holder (40) which moves toward base (10) to engage the knife in the crimped edge as the shell is rotated. Upon shooting of shell (14), the crimp material separates from casing (20) leaving the shell of a shorter length.
