Structure of energy-containing special-shaped hood cutter

Abstract

The invention provides an energy-containing special-shaped drug-shaped cover cutter structure, which includes a shell, an expansion charge column, an expansion charge chamber, a detonator, a wedge-shaped charge, an energy-gathering cover, a prefabricated cutting body, an energy-containing block, and a shell. It is a semi-closed rectangular structure, the upper part is closed, and the bottom is open downward. The energy collecting cover is assembled on the inner side wall of the shell, forming a cavity downward with the open part of the shell, and the prefabricated cutting body is arranged on the top of the energy collecting cover In the middle position, it is assembled with the energy-gathering cover by integral casting or fixed connection. It is in the shape of a sheet and faces the cavity, and the energy-containing block is filled between the energy-gathering cover and the prefabricated cutting body. The structural advantage of the present invention is that the prefabricated cutting body can significantly increase the penetration depth, and the embedded energy-containing block uses the energy-gathering cover as a buffer material, which significantly reduces the high-pressure impact of the detonation pressure of the explosive and reduces the formation of the energy-gathering cutting body. The loss of mass or energy in the process makes the shaped energy penetrating body of the cutter have both cutting and explosion damage capabilities.

Description

technical field

[0001] The invention belongs to the fields of engineering blasting and special blasting, and in particular relates to a cutter structure of an energy-containing special-shaped medicine-shaped cover. Background technique

[0002] Linear Shaped Charge Cutter (LSCC) refers to a kind of equipment that uses the energy-forming effect of the shaped charge and uses a wedge-shaped charge cover to perform relatively regular cuts on solid targets. Compared with traditional cutting methods such as mechanical cutting and gas cutting, the linear shaped energy explosive cutting technology has many advantages, such as high efficiency, fast speed, low cost, strong adaptability, easy operation, safety and reliability, less environmental impact, and wide application range. , has strong military and civilian value, and is widely used in aerospace, military, emergency rescue and civil blasting fields. At present, according to the different target properties of the focused cutter...
