超声波辅助铆接过程中将超声波能量施加到冲头上。先前的研究发现成形力降低[1]。目前的研究活动集中于在铆接过程中利用超声波软化机制的积极作用来连接高强度钢和铝的可能性。将功率为 1 kW 的超声波装置安装在 C 形铆接弓中，在铆接过程中叠加频率为 20 kHz 的振动。本文描述了超声波单元在铆接过程中的集成，并介绍了目前侧重于概念验证的研究成果。
Ultrasonic assisted clinching applies ultrasonic energy to the punch during the process. Prior studies detected a forming force reduction [1]. Current research activity focusses on the possibility to use the positive effects of ultrasonic softening mechanisms in clinching processes to join high-strength steel and aluminium. An ultrasonic unit with a power of 1 kW was installed into a c-shaped clinching bow to overlay a vibration with a frequency of 20 kHz onto the clinching process. This Paper describes the integration of the ultrasonic unit in the clinching process and presents current research results focusing on concept verification.
