Problems solved by technology

[0004] In order to overcome the problems of insufficient cutting ability and poor structural adaptability of commonly used wire cutting devices, this novel invention provides a special flexible energy-gathering wire cutter, which can perform shape adaptability according to the structural characteristics of the cut object. Adjust so that the bottom of the cutter's drug-shaped cover fits or is parallel to the cutting surface of the object to be cut, and under the action of high-energy explosives, the cutter uses the metal jet and shock wave formed by the cutter to quickly cut metal components

Embodiment 1

[0026] like figure 1 As shown, a flexible energy-concentrating wire cutter includes a housing 5 with a strip-shaped installation cavity, and the bottom of the housing 5 is recessed into the installation cavity to form an inverted V-shaped drug-shaped cover 1, such as figure 2 As shown, a number of opening slots 6 are opened from top to bottom along the radial direction of the casing 5 on the top of the casing 5 opposite to the explosive assembly.

[0027] The installation cavity is provided with an initiation component and an explosion component, and the explosion component includes a high-energy explosive 4, and the high-energy explosive 4 fills the installation cavity.

[0028] The detonation assembly includes a detonation charge 2, and a detonation hole 3 for placing a detonator is opened on the detonation charge 2. The explosive component is arranged in the installation cavity, and the detonating component for detonating the explosive component is arranged at one end of ...

Abstract

The invention discloses a flexible energy gathering line cutter, and belongs to the technical field of explosion cutting devices. The flexible energy-gathered wire cutter comprises a shell with a strip-shaped mounting cavity, wherein the bottom of the shell is provided with an inverted V-shaped explosive-shaped cover which is formed by sinking towards the interior of the mounting cavity, and the top, opposite to an explosion assembly, of the shell is provided with a plurality of open grooves from top to bottom in the radial direction of the shell; and a detonating assembly and the explosion assembly are arranged in the mounting cavity, the explosion assembly is arranged in the mounting cavity, and the detonating assembly used for detonating the explosion assembly is arranged at one end ofthe mounting cavity. The shape of the cutter can be adaptively adjusted according to the structural characteristics of a cut object, so that the bottom of the explosive-shaped cover of the cutter is attached to or parallel to the cut surface of the cut object, and under the action of high-energy explosives, and the cutter utilizes metal jet flow and shock waves formed by the cutter to quickly cuta metal component.

Description

technical field [0001] The invention relates to the technical field of explosive cutting devices, in particular to a flexible energy-gathering wire cutter. Background technique [0002] In some emergency rescue, anti-terrorism or combat assault processes, it is often necessary to quickly cut and remove some obstacles such as steel plates and steel pipes. Cutting with energy-concentrating wire cutters is a commonly used explosive cutting method. The charged metal wire cutter forms a metal jet, which cuts metal quickly under the action of the jet. [0003] However, the commonly used metal wire cutters have the following disadvantages: wire cutters with strong cutting ability have a large amount of charge and a fixed shape, and are generally only suitable for flat surfaces. It is suitable for cutting special-shaped structural parts; the shell of the cutting device with certain shape adaptability is generally made of lead-antimony alloy with less charge and weak cutting ability...
