Embodiment 1

[0037] A kind of explosive method of composite plate subsection distributing explosives, such as Figure 4 shown, including the following steps:

[0038] 1) Base plate and cladding plate 5; the base plate is Q345R with a specification of 2460*5960*20mm; the cladding plate is TA10 (titanium) with a specification of 2500*6000*4mm. Both the base plate and the cladding plate are rectangular; the surface-treated base plate and the cladding plate are installed on the fort.

[0039] 2) Arranging the frame; installing a frame 6 for blocking explosives around the cladding plate; wherein the frame is made of wood or fiberboard.

[0040] 3) charge; such as Figure 4 As shown, the cladding plate 1 is divided into 5 regions symmetrically in the direction of the central axis with respect to the central axis in the length direction, and divided symmetrically on both sides into the central region-2 and the region-two symmetrical regions on both sides. Two (3a, 3b), two areas three (4a, 4b)...

Embodiment 2

[0046] The present invention also provides a method for exploding circular composite plates: as Figure 5 shown, including the following steps:

[0047] 1) Substrate and cladding plate 8; the substrate and cladding plate that have been surface-treated are installed on the fort, and the shape of the substrate and cladding plate is circular; the specification of the substrate is 4020 mm in diameter and 20 mm thick; the cladding plate is TA10 (titanium), The specification is 4000mm in diameter and 4mm in thickness.

[0048] 2) Arranging the frame; a frame 9 for blocking explosives is installed around the circumference of the cladding plate 8 .

[0049] 3) As shown in the figure, charges; the cladding plate is divided into a central circular area 10 along the circular direction, an annular area 11 surrounding the area 1, and an annular area extending from the enclosing area 2 to the boundary of the cladding plate The area three 12; the low detonation velocity explosive is loaded...

Embodiment 3

[0055] In the selection of the basic cladding plate, the substrate can also be other common alloy steel or carbon steel; the cladding plate can be one or more of aluminum, copper, titanium, zirconium, tantalum, niobium or stainless steel. Among them, if the cladding plate is rare metals such as zirconium, tantalum, and niobium, due to its high melting point, the two-layer plate is prone to disunity, and a thin buffer layer of titanium plate is added between the substrate and the cladding plate. The way of distributing explosives for explosive welding is as described in the above two embodiments and will not be repeated here.

[0056] In order to compare the influence of the uniform charge distribution and segmented charge distribution methods on the combined interface wave, a pair of composite panels with the same size and different charge distribution methods were sampled for test analysis in the embodiment, and the samples were selected at the same position with the detonatio...

Abstract

The invention provides a composite board segmented explosive-distribution blast method. According to large-area composite board explosive welding, explosives are distributed in different segments at different detonation velocities; blast loads at all points of a shroud board are controlled to be basically kept within a certain range; the situation that big wave combinations containing gaps, cavities and other defects are generated due to metal melting as a result of an excessively high detonation velocity is avoided; consequently, the speed of collision between a base board and the shroud board is controlled, the overall bonding strength and deformation of a composite board can be changed quite beneficially, the problem of tearing of the shroud board in the explosive welding process can be solved quite beneficially, the bonding strength and the edge bonding quality of the composite board are improved, and the ideal goal that the whole interface of the composite board is in a tiny wave bonding mode is achieved.

Description

technical field [0001] The invention relates to an explosive welding method, in particular to an explosive welding method for segmented charge distribution of a composite plate. Background technique [0002] In the previous process of explosively welding metal composite panels, the traditional uniform charge distribution method was often used, and the interface bonding wave of the obtained explosively welded composite panels changed from small waves to large waves along the detonation direction, and when it reached a stable detonation, The interface wave waveform is still slowly increasing. The result is weak joint strength in parts, unbonded edges, or tearing of the cladding. Especially for the composite plate welded by the center detonation method, non-bonding or cladding plate tearing often occurs at a position 1800mm-2200mm away from the central detonation point, and the length is 10-30mm; similar phenomena also occur at both ends of the plate. called the boundary effe...
