Preparation method of uniform low stress cone shaped charge liner
A preparation method of a uniform low stress cone shaped charge liner includes the steps of multi-pass extrusion forming, vibration aging treatment, and cryogenic treatment. The step of multi-pass extrusion forming refers to 4 to 8 passes of extrusion deformation under the actions of a three-dimensional compressive stress and a deformation rate of 5 to 10 mm/s, having a deformation amount of 5 to 50% for each pass. The shaped charge liner prepared by the present invention has high dimensional accuracy, good geometric symmetry, low stress value, and excellent stability in the precise machining process and in use, which may significantly improve the penetration capability and stability of the shaped charge liner of high-explosive anti-tank warheads.
Packaging systems with sizing mandrels and related devices that can operate at reduced pressures suitable for low temperature explosives emulsions
Apparatus, systems, devices, methods with thin walled sizing mandrels that are capable of packaging low temperature explosives emulsions at high volumes and lower pressures. The packaging systems can include a rotating table having a vertical column comprising a plurality of circumferentially spaced apart clippers; a pump; and a tubular sizing mandrel in fluid communication with the pump. The tubular sizing mandrel has a downstream end segment that merges into a segment with a plurality of radially spaced apart, longitudinally extending flat outer surfaces, the flat surfaces can be bounded laterally (circumferentially) by chamfered edges.
