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.
