Application of Paste Emulsion Explosive and Explosive Forming Device of Titanium-aluminum Composite Plate

Abstract

The invention belongs to the field of titanium composite materials, provides a titanium-aluminum composite plate explosive molding device available for compounding a titanium plate with the thickness of less than 1 mm on an aluminum plate through explosive molding, and particularly provides use of a paste emulsion explosive in a titanium-aluminum composite plate explosive molding process. The device comprises a base, wherein a substrate is laid on the base; a compound plate is laid above the substrate; the substrate is the aluminum plate; the compound plate is the titanium plate; a support member is arranged between the aluminum plate and the titanium plate, so that a gap L is formed between the aluminum plate and the titanium plate; an explosive layer is laid on the titanium plate; a detonator is placed on the explosive layer; the titanium plate has the thickness of not greater than 0.2 mm; the explosive layer is a plate-like explosive layer formed by laying the paste emulsion explosive. The paste emulsion explosive is used in the composite plate explosive molding process, while the paste emulsion explosive can be laid on the titanium plate to form a plate-like explosive layer, so that the piercing, damage, deformation and the like for the titanium plate with the thickness of less than 1 mm due to explosion can be avoided effectively; a thinner titanium-aluminum composite plate can be obtained.

Description

technical field [0001] The invention relates to the field of titanium composite materials, in particular to an explosive forming device for a titanium-aluminum composite plate and the use of a paste emulsion explosive in the explosive forming process of a titanium-aluminum composite plate. Background technique [0002] Explosion welding is a solid phase welding method, usually used for welding between dissimilar metals. Such as welding between metals such as titanium, copper, aluminum, steel, etc., and the welding of these metal materials with different chemical compositions and physical properties is difficult to achieve with other welding methods. The metal clad plate produced by explosive welding is mainly used to replace expensive stainless steel and non-ferrous metals, and is widely used in chemical industry, shipbuilding, vehicles, military industry, aerospace and other fields. Titanium plate has high strength and low density, good mechanical properties, good toughnes...

AI Technical Summary

Problems solved by technology

After the above-mentioned explosives are used, the thickness of the titanium plates used for the composite is greater than 1 mm, and when the titanium plates are less than 1 mm or even thinner, because the titanium plates are too thin, it will be easy to explode when the above-mentioned explosives are used. Therefore, the explosive forming welding of such ultra-thin titanium plates cannot be realized
