Exothermic fusion welding device and process of metal rubber damping sandwich panel

Abstract

The invention relates to a metal rubber damping sandwich board heat-release fusion-welding device. The metal rubber damping sandwich board heat-release fusion-welding device comprises a machine table,wherein a metal rubber damping sandwich board is arranged on the machine table; the metal rubber damping sandwich board comprises a metal rubber damping board and a base board which are superposed; athermo-fusion welding agent is spread between the metal rubber damping board and the base board; an kindling agent is arranged at the outer side of the thermo-fusion welding agent; and a light groupfor heating the kindling agent to spontaneously combust is arranged beside the part, with the kindling agent, of the metal rubber damping sandwich board. The invention further relates to a metal rubber damping sandwich board heat-release fusion-welding process. The metal rubber damping sandwich board heat-release fusion-welding device is simple and reasonable in structural design, is easy to operate, is efficient and convenient, is high in safety, reduces damages, on the metal rubber damping sandwich board structure, of a heat-release fusion-welding way, is especially suitable for the fields such as aerospace, ships and cars, and has a wide application prospect.

Description

technical field [0001] The invention relates to an exothermic fusion welding device and process for metal rubber damping sandwich panels. Background technique [0002] With the increasing development of aerospace and cutting-edge military technology, traditional metal rubber is becoming more and more difficult to adapt to the technical requirements of extreme conditions such as vacuum, radiation and high / low temperature. And a new type of metal rubber material came into being. Its pure metal material is not afraid of the radiation environment, high / low temperature resistance, and has a long fatigue life. When subjected to alternating loads, the spatial network structure formed by the interlacing of metal wires inside the metal rubber can dissipate vibration energy through its own relative sliding, friction, extrusion, and deformation. In practical applications, flat metal rubber is often arranged as a damping layer, but its porous characteristics and extreme conditions make...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the size and self-weight limitations of metal rubber, the number and type of bolts need to change accordingly, which may bring inconvenience to installation and design;

[0005] (2) Bolt connection needs to make holes and other modifications to the base unit. In plate and shell structures such as foundations, the size and number of holes will have a certain impact on the natural frequency of the base structure and the distribution of power flow. It is difficult to judge and verify the degree of impact when the equipment is difficult to disassemble;

[0006] (3) When the surface area of ​​the base layer to cover the metal rubber area is large or there are ribs that need to be arranged with multiple pieces of metal rubber, if a large number of bolts are required to ensure a reliable connection between the metal rubber layer and the base layer, the amount of work is large, and holes must be drilled Inconvenient operation
