Abstract

The invention provides a novel efficient energy-gathering cutting device. The novel efficient energy-gathering cutting device comprises a charging housing, a shaped charge liner, an auxiliary structure and a charge. The charging housing is of a plate structure with an n-shaped section. The shaped charge liner comprises a shaped charge liner I and a shaped charge liner II. The shaped charge liner Iand the shaped charge liner II are of plate structures, the lower ends of the shaped charge liner I and the shaped charge liner II are connected to the front end of the inner wall of the charging housing, separately, and shaped charge liner connecting plates are arranged at the upper ends of the shaped charge liner I and the shaped charge liner II; the auxiliary structure is of a square plate structure and is arranged on the shaped charge liner connecting plates; and the charge is arranged in a cavity formed by the charging housing, the shaped charge liner and the auxiliary structure. By changing the angle between the shaped charge liner and the charging housing primarily and additionally mounting the auxiliary mechanism on the shaped charge liner, an enough explosive penetration abilitycan be obtained.

Description

technical field [0001] The invention relates to the technical field of blasting, in particular to a novel high-efficiency linear energy-gathering cutting device. Background technique [0002] Traditional shaped charges can be divided into the following three forms according to the form of metal jet formed after the detonation of the charge: the first type is shaped jet; the second type is explosively formed projectile (EFP); the third type is rod type jet. The head speed of the first type of shaped jet is generally higher, and the penetration depth is larger, but the utilization rate of the liner is low, and the penetration ability of the jet will be greatly reduced after the jet breaks. The second type of EFP is that after the detonation of the charge, the liner is deformed to form a high-speed projectile. The liner has a high utilization rate, is not sensitive to the explosion height, and has the advantages of a large penetration hole, but its penetration depth is relativ...
