A pipe loading module and its cutting cable processing device based on 3D printing

Abstract

The invention discloses a tube loading module and a cutting cable processing device based on 3D printing. The cutting cable processing device comprises: a printing module for printing out an inner tube, and filling the inner cavity of the inner tube with a fatty explosive ; The reversing module is used to bend the inner tube to a horizontal state, so as to facilitate subsequent loading into the outer tube; the tube loading module is used to output and clamp the outer tubes one by one, so as to facilitate the loading of the inner tube. The invention uses 3D printing technology to print the inner tube and fill the inner tube with fat-like explosives, so that the cross-section of the inner tube tends to the design standard, and also solves the inconvenience caused by the current use of fan explosives and charge. At the same time, use the existing special-shaped tube processing technology to process the standard outer tube, then put the inner tube into the outer tube, and finally stretch the outer tube to make the cross section of the outer tube smaller to clamp the inner tube, so as to obtain a standard shape Cut cord shape. This method only requires a few stretches, and it is extremely efficient, and the final product is very standard.

Description

technical field [0001] The invention relates to the processing technology of energy-gathering cutting wires, in particular to a cutting wire processing device based on 3D printing. Background technique [0002] The energy-gathering cutting cable is a kind of energy-gathering effect (commonly referred to as "Monroe effect"), that is, after the explosion of the explosive, the detonation product is cut at high temperature and high pressure to cut the metal material, and the blasting fragments are basically along the normal direction of the explosive surface. flying outside. After the charge with grooves is detonated, there will be a converging flow of explosive products with high speed and pressure on the axis of the groove (energy gathering angle), which will cause the explosives to explode within a certain range. Can concentrate. [0003] In the applicant's previous Chinese invention patent application (application number 2020104732555), the impact of the energy gathering a...

Problems solved by technology

However, because the round tube is filled with explosives in advance, the existing special-shaped tube processing method cannot be used, which is one of the reasons why the cutting wire processing technology has been stagnant for decades.

Moreover, the current level of cutting wire processing in China is not as good as that achieved by NASA in the United States.
