Technical Field
The invention relates to a pipe-pipe magnetic pulse welding centering device, and relates to the field of magnetic pulse welding.
Background
Under the multiple pressure of global climate change, energy crisis highlighting and environmental pollution aggravation, energy conservation and emission reduction are becoming the necessary way for realizing sustainable development of global automobile industry. Relevant research shows that the oil consumption is reduced by 6-8% when the automobile mass is reduced by 10%. The lightening of automobiles is one of the most effective measures to alleviate the above-mentioned stress. The aluminum alloy-high-strength steel composite welding structure is high in strength, corrosion-resistant and light in weight, can simultaneously exert the excellent performances of two metal materials, and is one of the structures which are considered preferentially for automobile light weight. However, the aluminum steel has significant differences in physical properties such as melting point, thermal conductivity, specific heat capacity and thermal expansion coefficient, and iron has extremely low solid solubility in aluminum, so that the weldability of dissimilar metals such as aluminum steel is extremely poor, defects such as shrinkage cavities and cracks and hard and brittle intermetallic compounds are easily generated in a welded joint, the mechanical properties of the joint are greatly reduced, and the application of an aluminum steel structure in the automobile field is limited.
Magnetic pulse welding is a novel high-energy forming technology, the forming speed is high, heating and no heat influence area are needed in the forming process, the dual advantages of high-speed forming and solid-phase connection are achieved, the strength of the obtained joint is higher than that of a weak base metal, and the problem caused by welding can be solved. The connection forms of the magnetic pulse welding include tube-tube, tube-rod, plate-plate and the like. When the pipe-pipe magnetic pulse welding is carried out, the coaxiality of the pipe, the pipe and the magnetic collector needs to be ensured, so that the stress of the pipe fitting is uniform, and the forming quality is ensured. However, in operation, it is difficult to determine whether the tube and the magnetic collector are coaxial.
