Embodiment Construction

[0038] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0039] A rock-breaking rod used to generate shock waves, such as Figure 1 to Figure 3 As shown, it includes a shell 1 , a metal wire 2 and an energetic material 3 .

[0040] The shell 1 is a hollow straight tube with both ends closed. The outer diameter of the shell 1 is 32 mm, the length is 200 mm, and the wall thickness is 1 mm. The shell 1 includes a straight tube 4 and an end cap 5 .

[0041] The straight pipe 4 is a tubular structure made of soluble aluminum-magnesium alloy; the high-strength aluminum-magnesium alloy can improve the compressive strength of the shell 1 . The outer surface of the straight pipe 4 is provided with multiple rows of groove assemblies along its axial direction, and each row of groove assemblies includes a plurality of rectangular grooves arranged along the circumference of the straight pipe 4, such as figure 2 As shown, th...

Abstract

The invention relates to a rock breaking rod used for generating shock waves and a manufacturing method of the rock breaking rod, and aims to solve the problem that mining of mineral resources is restricted due to the defect that the electric energy storage density is low when the mineral resources are mined through metal wire electric explosion. The rock breaking rod for generating the shock waves comprises a shell which is a hollow straight pipe with two closed ends; a metal wire is arranged along an axis of the shell, and two ends of the metal wire extend out of the shell and are fixed andmounted; an energetic material is filled between the metal wire and the shell, wherein the energetic material is solid, and comprises 70%-80% by mass of polytetrafluoroethylene and 20%-30% by mass ofaluminum powder; and a groove is formed in an outer surface of a straight pipe. The manufacturing method of the rock breaking rod for generating the shock waves comprises the steps of machining an endcover and the straight pipe, and machining a longitudinal groove and an annular groove in an outer surface of the straight pipe; fixing the metal wire to one end cover to penetrate through the straight pipe, and then firmly binding the end cover and the straight pipe; manufacturing the energetic material and filling the energetic material into the straight pipe; and mounting another end cover.

Description

technical field [0001] The invention belongs to the technical field of mining of mineral resources, and in particular relates to a rock-breaking rod for generating shock waves and a manufacturing method thereof. Background technique [0002] Mineral resources are an important material basis for economic and social development. At present, whether it is metallic minerals, non-metallic minerals or building stones, due to their high hardness, conventional tools have problems such as mining difficulties. Therefore, explosive blasting is mainly used in actual mining. Way. Although explosives and other pyrotechnic products have great technical advantages in rock breaking operations, explosive blasting and rock breaking not only pose a serious threat to the life safety of production personnel, but also have the disadvantage of poor environmental protection, which leads to the use of explosives for rock breaking mining. The regulations received are becoming more and more stringent,...
