Embodiment 1

[0027] For the double-sided explosive welding of stainless steel and steel, a protective cover and charge structure were invented, in which the size of the base plate is 2000mm×2000mm×20mm; the size of the double plate is 2000mm×2000mm×5mm.

[0028] refer to figure 1 , The double-sided explosive welding restraint cover includes: a shell, a buffer layer and a restraint net. The shell material is iron, its inner diameter is 3000mm, the wall thickness is 20mm, and its shape is a "bow" structure composed of a cylindrical shell and a sub-hemispherical shell. The height of the cylindrical shell is 1000mm, and the height of the sub-hemispherical shell is 500mm; the buffer layer is filled with waste Tires; the restraint net is steel wire mesh.

[0029] refer to figure 2 , the double-sided explosive welding charge structure includes: a restraint box, a supporting shell and explosives. Here, the constraining box is selected as a paper box, and its side length is 2000mm for the side ...

Abstract

The invention discloses a protective cover based on double-sided explosive welding and a charging structure. The protective cover can be repeatedly used and mainly comprises an outer shell, a buffer layer and a constraint net. The protective cover provides a closed environment for explosive welding, can effectively prevent an upper-layer composite plate and fragments from flying apart, reduces noise pollution and dust pollution and provides a safe and comfortable working environment for explosive machining. The charging structure comprises a constraint box, supporting shells and an explosive. The supporting shells are columnar shells shaped like the Arabic number '8' and evenly distributed along the inner surface of the constraint box, achieve a supporting effect, and enhance detonation at the boundary, thereby reducing the boundary effect. The upper surface and the lower surface of the charging structure are in fit with the upper-layer composite plate and a lower-layer composite plate, and the explosive is in a constraint state in any direction. Accordingly, the explosive detonation critical thickness is reduced, and the energy utilization rate is improved.

Description

technical field [0001] The invention belongs to the technical field of explosive welding, and in particular relates to a protective cover and charge structure based on double-sided explosive welding. Background technique [0002] Explosive welding is to use the powerful working ability of explosive explosion to push the doubler board to move at high speed and hit the substrate. Under the strong impact pressure, the metal at the interface between the substrate and the doubler plate exhibits fluid properties, and the metal atoms flow and penetrate into each other, and after cooling, they occlude each other, thereby realizing metallurgical bonding. After decades of development, explosive recombination between almost any metal can be realized now. Because the explosive composite board combines the advantages of two or more metals, it has the characteristics of excellent performance and low price. And compared with other composite materials, explosive composite has simple opera...
