Abstract
The utility model discloses an add foil sheet explosive welding device on pressure transmission layer includes base plate, clearance post, foil sheet, pressure transmission layer, explosive and detonator. The foil plate can be made of various metal materials. The pressure transfer layer can be made of a paper box for containing salt. The pressure transfer layer may be 1-10mm thick. The explosive can be low detonation velocity explosive. The method adds a pressure transfer layer between the explosive and the clad foil plate, which corresponds to the foil plate explosive welding problem in industrial production. The energy generated by explosion is transferred to the foil plate by the pressure transfer layer, so that the damage caused by direct contact of the sliding shock wave with the foil plate can be reduced. Meanwhile, salt crystals are adopted in the pressure transmission layer, so that the pressure transmission layer has better fluidity, more uniform thickness and easiness in installation. And under the high temperature that the explosion produced, salt gasification absorbs some heat, will effectively avoid the burning problem on foil plate surface. Compared with a metal protection plate, the cost of the salt is extremely low.

Background
Explosive welding is an excellent welding technology for connecting the same or different materials, and can be used for processing composite plates or pipes. It utilizes the explosive energy of explosive to produce high-speed collision between materials. The high temperature and high pressure generated by collision melt and diffuse the base and clad metals, and after cooling, a welding surface integrating the advantages of fusion welding, diffusion welding and pressure welding is formed on the interface.
The explosive for explosive welding has uniform thickness, and can generate sliding shock waves after being detonated by a detonator, so that the composite plate or the composite tube is accelerated to impact the substrate or the composite plate at high speed. However, the detonation gases generated by the detonation of the explosive are extremely hot and can burn surfaces when they contact the doubler plate. The foil plate is a plate with the thickness of less than 200 mu m, and the use amount of the clad plate metal can be effectively reduced by adopting the foil plate as the explosive welding clad plate. In the explosive welding of the foil plate as the composite plate, the burn phenomenon has more serious influence on the quality of the explosive welding composite plate. In addition, the thickness of the foil plate determines that the energy for resisting deformation is poor, and the acceleration action of the sliding shock wave easily causes the conditions of fracture, turnover and the like of the foil plate, so that the composite plate product is unqualified.
In order to solve the problems in the existing foil explosion welding technology, some solutions are proposed in the existing patent documents. The Chinese patent with the application number of 00266222.1 discloses an improved titanium-steel explosion welding composite tube plate, which aims to save the use amount of titanium materials or non-ferrous metal materials. The technology effectively reduces the requirement of the composite plate thickness by adding a layer of corrosion-resistant sealing ring. The technology provides improvement on the use of the explosion welding composite board in a multi-layer mode, but does not provide an effective solution for the production of the explosion welding composite board.

The technology provides an improvement on the traditional explosive welding device, and can effectively overcome the influence of the impact pressure and the boundary effect of the explosive welding on the foil composite plate. However, the technical device is complex and complex to operate, the production cost of the composite board is greatly increased, and the practicability of the technology is influenced.

However, the thickness of the composite titanium plate adopted by the technology is 3-6mm, and the technology cannot ensure the combination quality of the foil plate explosion welding composite plate relative to the thickness of the foil plate below 200 mu m.
The Chinese patent with the application number of 200710025051.X discloses an explosive welding method for ultrathin metal composite plates, and aims to realize the explosive welding of the ultrathin metal composite plates. The technology provides a layer of butter and soft paper with a certain thickness in the protection problem of the surface of the compound plate, and can protect the surface of the compound plate to a certain extent. However, this method is a technique commonly used in the industry, and butter and soft paper cannot completely and effectively protect foil plates in explosive welding of foil plates. For example, the grease and soft paper thickness are increased to provide effective protection, the viscosity of the grease determines the poor uniformity of the thickness of the grease, and finally the movement of the compound plate is influenced.
The Chinese patent with application number 200910262860.1 discloses a double-vertical explosive welding charging method for large-area thin plates, and aims to solve the problems of fixing of a composite plate, mounting of a base composite plate, arrangement of explosives and the like. The technology improves the efficiency and the standardized operation degree of explosive welding operation and can ensure the accuracy of double-vertical explosive welding charging parameters. The technology is more concerned with the explosive welding of large-area thin plates, and no effective solution is proposed in the field of explosive welding of foil plates.

The technology designs the pasty emulsion explosive for explosive welding of thin plates by changing the formula of the emulsion explosive. The designed explosive is easy to produce, stable in performance and good in fluidity. However, the technical innovation is in the direction of explosive welding, and the protection problem of the composite plate during the explosive welding of the foil plate is not considered.

In the technology, the foil plate is adhered to the lower bottom surface of the protection plate, and the protection plate is accelerated to impact the substrate after detonation, so that the foil plate and the substrate are welded. However, according to the empirical formula of the thickness of the molten metal jet between the matrix layers, the collision of the protective plate generates a metal jet with a thickness of 2% -4%, which affects the welding quality of the foil. Simultaneously, the protection shield thickness that the technique adopted is 5mm, and for the kinetic energy of foil plate self, kinetic energy that the protection shield has is higher, therefore it can cause the injury to the foil plate when striking. Meanwhile, the protection plate can deform after being used once and cannot be reused, so that the production cost is increased.

The technology is characterized in that auxiliary plates are added outside the foil plates, and the foil plates in the middle of the two auxiliary plates are welded through the impact between the two auxiliary plates. The technology adopts two auxiliary plates to assist welding, but the two plates can generate processing deformation after one explosion, and the two auxiliary plates can not provide assistance for a straight foil plate continuously in subsequent use. The non-recyclable two-plate material is costly and may result in increased production costs.
The chinese patent with application number 202011236548.8 discloses a tungsten foil explosive welding method, which aims to solve the explosive welding problem of brittle tungsten foil. The method can provide a solution for tungsten foil explosion welding, but the same also has the cost problem of protecting the plate. For explosive welding of other copper and aluminum materials which are easy to weld and have better ductility, a mode of adding a protection plate is not needed.
