Research on Influencing Parameters of Ultrasonic Welding Quality of Car Wheel Eyebrow

Abstract

∗The main parameters that affect the quality of ultrasonic welding are welding time, holding pressure time, welding depth, trigger air pressure, welding air pressure, and the vibration frequency and amplitude of the ultrasonic generator. Ultrasonic vibration when the equipment is installed at a fixed point The frequency and vibration amplitude are fixed, and the ultrasonic trigger mode of the equipment used in this paper is delayed trigger, and only needs to delay until the set time to trigger the ultrasonic. Therefore, this article mainly studies the effects of holding pressure time, welding depth, and welding air pressure on the welding quality of car wheel eyebrows. Orthogonal experiments of welding parameters were carried out with drawing force and appearance as indicators to explore the relevant technical parameters that can achieve the best welding quality.
