Abstract

The invention provides an ultrasonic vibration-assisted electromagnetic locking welding device and method, comprising: a lower mold, an ultrasonic auxiliary device is arranged in the lower mold, and a first metal plate and a second metal plate are placed on the top of the lower mold an upper mold, the upper mold is fixedly arranged above the lower mold, and the upper mold is arranged coaxially with the lower mold; a controller, the controller is arranged on the top of the upper mold. The electromagnetic locking welding device and method assisted by ultrasonic vibration provided by the present invention do not need to use rivets or pre-drilled holes, and use pulsed magnetic field force to process the plate, and through the assistance of ultrasonic vibration, the plasticity of the material in the connection process is enhanced Deformation ability, using electromagnetic pulse welding, avoids the cracking defect caused by the concentration of tensile stress on the neck of the joint, significantly improves the mechanical properties of the joint, high connection strength, easy to control, high efficiency, and simple operation.

Description

technical field [0001] The invention relates to the technical field of electromagnetic forming connection, in particular to an ultrasonic vibration-assisted electromagnetic locking welding device and method. Background technique [0002] With the development of aviation manufacturing and automobile manufacturing, the requirements for the connection of mechanical parts are getting higher and higher, and the requirements for riveting technology are also getting higher and higher. Electromagnetic riveting technology, as a new type of joining process, has been paid more and more attention by research institutions and manufacturing enterprises. Electromagnetic riveting is a riveting process that uses the eddy current repulsion generated between two-stage coils to make the rivet plastically deformed. Due to the high loading rate, large strain rate, uniform deformation of the rivet shaft, and effective prevention of composite material damage, it has been used for the connection of...
