Embodiment

[0026] In Fig. 1, 1 is a cylindrical shell, made of aluminum, with a smooth surface, no cracks and blisters, and its molding dimensions are: outer diameter 10mm, wall thickness 1mm, height 25mm. The shell is filled with secondary explosive 2, ignition powder 3 and fire transmission element 4 sequentially from bottom to top, secondary explosive 2 is RDX with a density of 1.0g / cm 3 , the filling height is 5mm. Ignition powder 3 is made up of combustible agent, oxidizer and binding agent, and filling height is 4mm, and wherein combustible agent is magnesium powder, and content is 20%, and oxidizer is red lead (Pb 3 o 4 ), the content is 80%, the adhesive is a shellac solution with a concentration of 4%, and the content is 2 times of the total content of the combustible agent and the oxidizing agent. The fire transmission element 4 is a cylinder made of lead metal, with an outer diameter of 9.2mm and a height of 16mm. Its outer cylindrical surface is in interference fit with th...

Abstract

The invention belongs to the technique field of detonating equipment, the invention mainly relates to exciting equipment of detonator and detonator made by the equipment. The exciting equipment Comprises an open shell which is like a barrel, the surface of the shell is interference fit with inwall of the shell. It is filled with high explosive, amorce, igniting primer or delayed element, the height of high explosive layer, amorce layer, igniting primer or delayed element is separately 0.5~2 times ,0.25~2 times and 1~6 times of the external diameter of the shell. Charge density of the high explosive layer is 0.4~1.2 g / cm3, and charge density of the amorce layer is 0.5~2.5 g / cm3. Igniting primer or delayed element compromises a piece of metal whose shape is like a column. The surface of the metal is interference fit with inwall of its exteriority, there is a through hole inside the metal, else fill delayed explosive. The invention regards the exciting equipment as an individual element. It benefits to concentrating on producing and to dispersal use, it also benefits to industrial production continuously, moreover, many kinds of high-safety detonator according to its different use.

Description

Technical field: [0001] The invention belongs to the technical field of explosive detonating materials, and in particular relates to an excitation device for a detonator and a detonator made using the device. Background technique: [0002] As the detonating body of insensitive explosives, detonators are widely used in military, high-tech fields and civil engineering. The detonators currently in use all use composite charge technology, and the typical structure is to use relatively insensitive high-power explosives as the secondary charge, use sensitive priming charges as the main charge, and use a variety of ignition devices as the first ignition energy. . First the priming charge is detonated, and the priming charge detonates the strong explosive again. All primary explosives are sensitive to various primary ignition energy sources, such as thermal energy, electrical energy, light energy, radiation energy, mechanical energy, etc. In the present composite charge detonator...
