Abstract

The invention relates to a device for electromagnetic pulse welding of metal rubber damping sandwich pipes and a working method thereof. The device comprises a first electromagnetic pulse module and asecond electromagnetic pulse module; the first electromagnetic pulse module and the second electromagnetic pulse module both comprise alternating-current power supplies, transformers, capacitor sets,high-voltage switches and annular coils; input ends of the alternating-current power supplies are connected with input ends of primary windings of the transformers; and the high-voltage switches areconnected with the capacitor sets in parallel to output ends of secondary windings of the transformers after serial connection with the annular coils. Compared with the prior art, the device uses an electromagnetic pulse welding technology for finishing welding, achieves a certain meaning on research of vibration reduction, energy absorption and impact resistance of pipeline systems under complicated environments, and has the advantages of low damage to base pipes, large welding area, reliable welding, safe operation, energy conservation, environmental protection and the like.

Description

technical field [0001] The invention relates to the technical field of new metal material welding, in particular to an electromagnetic pulse welding device and working method for metal rubber damping sandwich tubes. Background technique [0002] With the development of industrial technologies such as aerospace, marine chemical industry and nuclear energy equipment, traditional rubber materials are difficult to meet the technical requirements of complex environments such as high and low temperature, and heavy load impact. A new type of metal rubber material emerges at the historic moment, which can meet the special needs of aerospace, space vehicles and civilian products, and solve the problems of damping, vibration reduction, filtration, sealing, Throttling, heat conduction and other issues. In practical applications, metal rubber is often arranged as a damping layer to reduce vibration and impact, but its porous characteristics and extreme conditions make connections diffi...
