Problems solved by technology

During martyrdom, the explosives on the same doubler board explode almost at the same time, which is different from the non-simultaneous detonation of the central detonation method. However, if the martyrdom method is adopted, it will cost more and have higher requirements for operation and equipment
At present, there is no mature equipment to apply the explosion compounding method of sacrificial explosion.
[0006] In addition, metal plate explosion composite technology usually adopts the operation method of single plate open-air explosion, which will generate a lot of dust, cause great environmental pollution, low output, and poor economic benefits

Embodiment 1

[0043] Such as Figure 1-2 As shown, a device that can prepare multiple explosive composite metal sheets at the same time, including: explosive composite drum 1, base 2, transmission device 3 and motor 4;

[0044] The equipment capable of preparing a plurality of explosive composite metal sheets at the same time is a bottom-closed vertical drum, and its inner wall is uniformly provided with four explosive composite surfaces 5 parallel to the axis, the explosive composite surfaces 5 are planes, and the explosive composite surfaces Clamping devices 501 are provided at the four corners, and a shaft 101 is provided at the center of the bottom of the explosive composite drum 1; the clamping device 501 is a fastener with an angle steel, and the four corners of the composite metal plate are held tightly by the angle steel to achieve the purpose of fixing; The pre-plywood is attached to the explosive composite surface so that it can be stably stressed, and the pre-plywood is fixed by ...

Embodiment 2

[0052] A method for simultaneously preparing multiple explosive composite metal sheet devices, comprising the following steps:

[0053] S1. Surface polishing treatment: Surface polishing treatment is carried out on the base plate and double board respectively; if there is an interlayer metal plate, both sides of the interlayer metal plate are polished;

[0054] S2. Pre-assembly: Align the base plate with the doubler plate, weld and pre-fix at the four corners to make a pre-laminated plate; if the clamping position of the clamping device 501 exceeds the upper surface of the doubler plate during clamping, it may affect the explosive compounding In order to keep the plate firmly on the explosive composite surface 5 and make the clamping position of the clamping device below the double plate, the base plate and the double plate must be pre-assembled.

[0055] S3. Explosive distribution: Lay explosives on the compound board, the thickness of the explosives is 18mm;

[0056] S4. Inst...

Embodiment 3

[0066] Similar to Example 1, the difference lies in that the explosive composite surface is a curved surface, so as to prepare the explosive composite board with the base plate and doubler board as curved surfaces, and meanwhile, the explosive board should also be prefabricated into a suitable curved surface.

Abstract

This case involves a device that can prepare multiple explosive clad metal sheets at the same time, including an explosive clad drum, a base, a transmission device and a motor; On the surface, the four corners of the explosive composite surface are provided with clamping devices, and the center of the bottom of the explosive composite drum is provided with a shaft; The rod is rotatably connected to the base through the bearing arranged in the shaft groove; in the present invention, except for an explosive composite plate equipped with a detonating cap, the explosives on the other plates are all detonated by way of sacrificial detonation, which avoids the disadvantages of the central detonation method, Effectively eliminate or reduce the boundary effect, and detonate in the rotation, high product quality, suitable for the production of multiple large and medium-sized explosive composite panels, high production efficiency, and strong practicability.

Description

technical field [0001] The invention belongs to the field of explosive composite technology, and in particular relates to a device capable of simultaneously preparing a plurality of explosive composite metal plates and a method for using the same. Background technique [0002] Metal plate explosive composite technology is a composite material processing technology that uses the huge energy generated by explosives to instantly composite two or more similar or dissimilar materials together. [0003] Boundary effect is a common problem in metal explosion welding using central detonation method. The existence of boundary effect greatly reduces the bonding strength and recombination rate of the joint surface of metal explosive clad plate. 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...
