Problems solved by technology

This product is designed for unidirectional linear energy-concentrating cutting. The existing similar products on the market have the characteristics of high cost, limited range of material sources, and inconvenient production. precious metals; and high-energy explosives are used as the charge, which greatly restricts the application and promotion of this technology

Embodiment Construction

[0008] The structure of this product is shown in the figure: 1 is the shell of the blasting cutting tube, 2 is the charge of the cutting tube, and 3 is the drug cover of the cutting tube. Shell 1 is mainly made of PVC pipes widely used in the market, and cartridge 2 is made of ordinary industrial explosives. Different explosives can be used according to different use environments. For example, colloidal emulsion explosives with strong water resistance can be used for underwater blasting and cutting. Powdered explosives can be used for cutting without water resistance requirements, and profile angle steel can be used for the liner cover 3 . The blasting tube is easy to make and can be made in real time according to the cutting site conditions. In the case of plane cutting, the length of the blasting tube can be made up to one meter; in the case of cutting curved steel parts, the blasting tube can be made It is short enough to ensure the blasting height of the cutting tube and e...

Abstract

The invention aims at providing a cumulative blasting coupe pipe and the manufacture method of the cumulative blasting coupe pipe. The cumulative blasting coupe pipe comprises a shell, a cartridge bag and a shaped charge liner. The shell is tube-shaped. The shaped charge liner is placed into the shell and then a shell lumen is isolated into a charge cavity and a energy concentration hole. The cartridge bag is packed into the charge cavity. The shell is polyvinyl chloride (PVC) pipe. The cartridge bag is packed with ordinary industrial explosives. The shaped charge liner is made of angle iron. The cumulative blasting coupe pipe can reduce the dismantling cost enormously, reduce the operation difficulty and improve the cutting efficiency.

Description

technical field [0001] The invention relates to a blasting cutting pipe, which is mainly used for cutting large metal parts such as large shipwrecks and metal blocks which are inconvenient to be cut by traditional methods. Background technique [0002] The energy-shaping effect was first used to deal with armor-piercing projectiles against tanks. Since the Second World War, the military application and research of energy-shaping charges have greatly promoted its development in the industrial field. At present, it has also been widely used in civil blasting. There are mainly four charging methods in the application of blasting: 1. Axisymmetric axial shaped charge for penetrating blasting; Axisymmetric radial shaped charges for surface blasting, pre-splitting blasting, cutting blasting, and blasting for correcting oil drilling deflection; 3. Used for shaking loose rocks, destroying hole walls, shearing core columns with a diameter of more than 1 m, Axisymmetric circumferentia...
