[0002] Explosion ultra-high pressure bimetallic welding composite usually involves loosening the soil, then laying a substrate on the soil, laying steel balls on the upper side of the substrate and then laying a clad plate, laying explosives on the upper side of the clad plate, and setting a detonator at one end of the explosives. After the detonator ignites the explosives, the steel balls at the positioning intervals are extruded between the clad plate and the substrate, and the clad plate and the substrate are compound welded into one body to form a composite plate.

[0003] Chinese Patent Application for Invention CN105234548A discloses a double-sided explosion welding rigid and flexible comprehensive protection device and protection method, which respectively sets a substrate and a clad plate on both sides of the explosives, thus making full use of the energy generated by the explosion of the explosives and increasing the utilization rate of explosives by about 40%. The following technical problems exist in this technical solution: 1) It realizes the buffering of the explosion through a flexible protective wall. After the explosion is completed, the flexible protective wall will be damaged. When the metal plates are compounded next time, it is necessary to re-place the flexible protective wall, and the placement efficiency of the protective wall is low, which results in low production efficiency of the bimetallic plates and very inconvenient operation.

[0024] Hanging ears 6 are arranged on the outer wall of the upper box body 2 to facilitate the connection between the upper box body 2 and the bimetal composite soldering table. A buffer pressing plate 7 is arranged around the bottom of the lower box body 1 to facilitate the connection between the lower box body 1 and the bimetal composite soldering table.

[0025] A filler 3 is filled between the upper box body 2 and the lower box body 1. The filler 3 is compressible, so it can buffer between the upper box body 2 and the lower box body 1. The filler 3 is hard particles with a particle size of 0.5 - 5 mm. In this embodiment, the filler 3 is sand grains. The height of the filler 3 is 1 / 5 - 1 / 2 of the distance between the top of the upper box body 2 and the bottom of the lower box body 1. A filling hole 11 is opened at the top of the upper box body 2 to facilitate injecting the filler 3 into the lower box body 1.

[0028] Furthermore, a reinforcing plate 8 is arranged between the pressing plate 5 and the pressing column 10 to enhance the connection strength between the pressing plate 5 and the pressing column 10. The reinforcing plate 8 is welded to both the pressing plate 5 and the pressing column 10. In this embodiment, 3 - 6 reinforcing plates 8 are arranged at intervals around the pressing column 10.
