Robotic Ultrasonic Riveting Auto Tuning Mudguard
Components of Ultrasonic Welding (Horn, Booster and Transducer)
They can amplify the amplitude at a particular ratio step by step. For example, the transducer amplitude is 6mm, the booster can amplify it triply to 18mm, and then the horn can make it to 36mm. However, the work life of horn would be shortened with the amplification of amplitude. The required amplitude differs with the welding material.
Ultrasonic welding, like butt welding, spot welding, penetrating welding, riveting, piercing is wildly applied in automotive interiors. Ultrasonic butt welding can be used in reflector and VSS(vehicle speed sensor). Ultrasonic spot welding in sound-proof cotton of engine cover, trunk and wheel casing, and hallstand felt. Ultrasonic penetrating welding in rear spoiler air-inlet grille and air flue of dashboard. Ultrasonic riveting in air outlet of air-conditioner, rear mirror, doorknob, handguard and so on. Ultrasonic piercing in bumper.
There are three common horn material:
high price, excellent performance good toughness and low loss, difficult to be processed;
Its amplitude can reach to 60mm.
low price, fast loss, easy to be processed;
Its highest amplitude less than 300mm.
too hard to be made as horn;
its highest amplitude less than 25mm;
It is suitable for cutting but the blowpipe need to be added in for its cooling.
