Description
technical field [0001] The invention relates to the technical field of forming performance testing of metal plates under ultrasonic vibration, in particular to an ultrasonic vibration-assisted metal plate cupping test device and a method for using the test device. Background technique [0002] Ultrasonic vibration-assisted metal plastic forming process is a special plastic processing process in which ultrasonic vibration is applied to metal materials or molds in metal plastic forming. Studies have shown that applying vibration to the mold or workpiece during metal plastic forming can improve the plasticity of metal materials, reduce the deformation resistance of metal materials, and greatly improve the surface quality of metal plastic forming parts and the service life of the mold. The process can be applied to metal drawing, metal wire drawing, metal extrusion, metal welding and metal rolling, etc. However, the current theoretical research on ultrasonic vibration-assisted ...
