Embodiment 1
[0021] Embodiment 1: 1) First, the carbon steel punching diamond mesh is formed by molding and folding technology to form the pyramid structure core 1, then the formed pyramid structure core 1 and the panel 2 are cleaned to remove oil stains and rust, and brazing is used to Pyramid structure core 1 and face plate 2 are welded to form a pyramid structure lattice metal sandwich panel, see figure 2 ;
[0022] 2) Then, according to the space size of the hole 4 in the pyramid structure core 1, a cutting machine is used to cut the block foamed pure aluminum into a triangular prism or a trapezoidal prism 5 that is compatible with the space size of the hole 4 in the pyramid structure core 1;
[0023] 3) Finally, a layer of casting glue is evenly coated on the contact surface of the triangular prism or trapezoidal prism 5 and the pyramid structure core 1, and then the triangular prism or trapezoidal prism 5 is inserted into the hole 4 of the pyramid structure lattice metal sandwich pl...
Embodiment 2
[0024] Example 2: 1) First, the flattened expanded metal mesh was formed by molding and folding technology to form a pyramid structure core 1, and then the formed pyramid structure core 1 and panel 2 were cleaned to remove oil stains and rust, and laser welding was used. Weld the pyramid structure core 1 and the face plate 2 to form a pyramid structure lattice metal sandwich panel, see figure 2 ,;
[0025] 2) Then, according to the space size of the hole 4 in the pyramid structure core 1, a cutting machine is used to cut the block foam aluminum alloy into a triangular prism or a trapezoidal prism 5 that is compatible with the space size of the hole 4 in the pyramid structure core 1;
[0026] 3) Finally, a layer of Loctite is evenly coated on the contact surface of the triangular prism or the trapezoidal prism 5 and the pyramid structure core 1, and then the triangular prism or the trapezoidal prism 5 is inserted into the hole 4 of the pyramid structure lattice metal sandwich ...
Embodiment 3
[0027] Example 3: 1) First, the flattened carbon steel plate is molded and folded to form a corrugated structure core 3, and then the formed corrugated structure core 3 and panel 2 are cleaned to remove oil stains and rust, and brazing or laser is used. Welding the corrugated core 3 and the face plate 2 to form a lattice metal sandwich panel with corrugated structure, see figure 1 ;
[0028] 2) Then, according to the space size of the hole 4 in the corrugated structure core 3, a cutting machine is used to cut the block-shaped foamed pure aluminum into a triangular prism or a trapezoidal prism 5 that is compatible with the space size of the hole 4 in the corrugated structure core 3;
[0029] 3) Finally, a layer of casting glue is evenly coated on the contact surface of the triangular prism or trapezoidal prism 5 and the corrugated structure core 3, and then the triangular prism or trapezoidal prism 5 is inserted into the hole 4 of the corrugated structure lattice metal sandwich...
