Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model; below in conjunction with accompanying drawing of the present utility model; the technical solution of the utility model is carried out clear, complete description; based on the embodiment in the application; other similar embodiment that those of ordinary skill in the art obtain under the premise not making creative work, all should belong to the scope of the application protection.
Embodiment one:
As depicted in figs. 1 and 2, a kind of metal solder honeycomb top board, top board includes crust 1, layer structure, bindiny mechanism 3 and bindiny mechanism 4, and bindiny mechanism 3 is positioned at one end of layered structure, and bindiny mechanism 4 is positioned at the other end of layered structure. Described bindiny mechanism 3 includes T-slot 31, and bindiny mechanism 3 is vertical with layer structure, and T-slot 31 is positioned at the side of top board. Bindiny mechanism 4 is arranged along the bottom surface of top board, bindiny mechanism 4 is provided with the groove that opening reduces, the effect of T-slot 31 is to install sealing joint strip, the effect of bindiny mechanism 4 is to be enclosed in inside sheet material by layer structure, the effect of the groove in bindiny mechanism 4 is to install sealing joint strip, makes intact the coordinating of mechanism 4 and car body.
The number of plies of layered structure is be more than or equal to 3, and layered structure includes sheet-metal layers and keriotheca, the outermost layer of layer structure and innermost layer respectively sheet-metal layers, and described sheet-metal layers welds with keriotheca, welds between described keriotheca.
As shown in figures 1 and 3, layer structure is 3 layers, being followed successively by: sheet-metal layers 21, welding keriotheca 22, sheet-metal layers 21, sheet-metal layers 21 passes through Welding with welding keriotheca 22, and honeycomb 221 cross section of welding keriotheca 22 is regular hexagon, this kind of layer structure light weight, bending resistance is good and isotropism, and firmly performance is good between layers, and security performance is high, suitability for secondary processing is good, has the effect that sound absorption is heat insulation.
As shown in Figure 2, layer structure is 5 layers, it is followed successively by: sheet-metal layers 21, punching press keriotheca 23, punching press keriotheca 23, punching press keriotheca 23 and sheet-metal layers 21, each through Welding between punching press keriotheca 23, between sheet-metal layers 21 and punching press keriotheca 23, the metallic plate of this kind of layer structure use is minimum, light weight, cost is low.
