Problems solved by technology

Due to the small distance between the two doubler plates, it is difficult to lay the explosives, and the explosives will also cause the doubler plates to deform, which not only makes the thickness of the explosives uneven, but also affects the distance between the base and doubler plates.

Embodiment Construction

[0026] 1. The doubler plate is 5mm wider than the base plate, the groove depth of the fixed block is 5mm, and the groove width is 2mm.

[0027] 2. The double board is 10mm longer than the base plate, and 5mm is left on each side for drilling and fixing.

[0028] 3. Use 65# powder as the explosive, and the charge thickness is 4cm, so the distance between the two grooves is 4cm.

[0029] 4. The distance between the base plate and the base plate is 4mm, and the gap is made of stainless steel balls with a diameter of 4mm, which are spot welded on the base plate, so the distance between the two grooves and the two sides of the fixed block is 24mm.

[0030] The final explosive welding composite rate is 100%.

Abstract

The invention relates to a double-vertical explosive welding charging method of a large-area thin plate. Through comprehensively applying a critical proportion testing and determining technology of an explosive, a compound plate three-dimensional comprehensive fixing technology as well as a basal and compound plate integral installation technology, the invention not only solves the problems of deforming of a large-area thin compound plate and ensures the stability and accuracy of the double-vertical explosive welding charging parameters, but also greatly enhances the operation efficiency and the standardized operation degree.

Description

technical field [0001] The invention relates to a powder charging method for Shuangli explosive welding, and belongs to the technical field of explosive welding and metal composite materials. Background technique [0002] Explosive welding technology and explosive composite materials have been widely used in various fields such as petroleum, chemical industry, shipbuilding, electric power, aviation, aerospace, salt production, alkali production, metallurgy, atomic energy, mining, transportation, and machinery manufacturing. [0003] In the third issue of "Explosive Equipment" in 2007, a new method of double-vertical explosive welding was published, which can save 2 / 3 of explosives, and can reduce most of the impact of explosion shock waves on the surrounding environment. The promotion and application of this method will have a broad impact on the technical fields of explosive welding and metal composite materials. [0004] But because the double vertical explosion welding m...
