Description

Technical Field

[0001] The utility model belongs to the technical field of ammunition shell disassembly, and in particular relates to a device for disassembling arc-shaped shell parts of ammunition. Background Art

[0002] Scrap ammunition not only takes up inventory, but is also a major source of danger. The safe disposal and resource recycling of scrap ammunition is a realistic problem facing ammunition companies now and in the future. In the process of safe disposal and resource recycling of scrap ammunition, the ammunition needs to be subdivided and disassembled, and the functional and characteristic components need to be separated for recycling. Generally, ammunition disassembly is mainly done manually, using special wrenches, belt wrenches and other tools to disassemble the ammunition.

[0003] However, it is very difficult to disassemble some ammunition parts, such as extended-range ammunition, special ammunition, rocket engine parts, or curved shell parts such as tail cones and tail arcs. First, these curved shell parts may not have wrench grooves, which makes it impossible to use special wrenches. Second, due to the shape restrictions of these curved shell parts, tools such as belt wrenches and pipe pliers are prone to slipping on the curved surface when exerting force, thus failing to loosen the threaded connection. In addition, considering the recycling of parts, especially for those curved shell parts that are difficult to process and have characteristic markings, it is often necessary to avoid them from being damaged, and non-destructive disassembly is required.
