Modular exploding welding explosive charging unit and modular explosive charging splice-paving method

Abstract

The invention discloses a modular exploding welding explosive charging unit. The modular exploding welding explosive charging unit comprises cuboid grid type explosive charging units consisting of wall surfaces and bottom surfaces, wherein inner cavities of the grid type explosive charging units are divided into a plurality of explosive charging cavities in rows, and all grids of the inner cavities of the grid type explosive charging units are separated into structures communicating with each other by the hollowed wall surfaces. The invention further discloses a modular explosive charging splice-paving method of the modular exploding welding explosive charging unit. Structural materials of which the physical and chemical properties are matched with the exploding wave spreading properties of explosive are selected, a series of explosive charging units of which the length, width and height geometric sizes are modular are made, and an adhesive and the powdery explosive are mixed and poured in the explosive charging cavities so as to realize explosive charging solidification and form modular explosive charging. The exploding welding explosive is poured in the explosive charging units,so that the current field site explosive charging operation is changed into production line explosive charging, the manual explosive charging operation procedure is reduced, and the safety of exploding welding operation is improved.

Problems solved by technology

There are too many manual on-site field operations in the current laying method, which not only reduces the safety, but also generally has poor uniformity of charge thickness and density, which makes it difficult to guarantee the quality stability of the prepared metal composite materials. Limits the popularization and application of explosive composite metal materials

[0003] Chinese patent ZL 201310282589.4 discloses an explosive compound special structure explosive, which improves the charging method, can improve the thickness consistency of the explosive, and ensure the density and uniformity of the explosive, but the design of the charging cavity does not take into account the impact of the cavity wall material. Barrier Effects on Detonation Performance of Explosives

The cavity wall structure designed by this patent leads to the propagation of the detonation wave among the charge cavities through the explosive detonation. Compared with the natural propagation of the explosive detonation wave, it is equivalent to the introduction of interference factors, which are harmful to the explosive welding composite. The interface quality has a negative impact; and the thickness of the structural explosive developed by this patent is directly controlled by the height of the cavity. According to the size of the metal plate to be explosively welded, the pre-processed charge is formed, which is equivalent to customizing non-standard explosive products and cannot form quantitative products. Popularize and apply to explosive welding preparation of metal clad plates with different geometric sizes
