2000W 20khz Pzt8 Ultrasonic Welding Transducer With Booster And Steel Horn

The piezoelectric ceramic transformer uses the Piezoelectricity of the polarized piezoelectric body to achieve voltage output. The input part is driven by a sinusoidal voltage signal, which generates vibration through the inverse Piezoelectricity. The vibration wave is mechanically coupled to the output part through the input and output parts, and the output part generates charges through the positive Piezoelectricity, realizing the twice transformation of electrical energy mechanical energy electrical energy of the piezoelectric body, and obtaining the output voltage at the resonant frequency of the piezoelectric transformer. Compared with electromagnetic transformers, this has the advantages of small size, light weight, high power density, high efficiency, resistance to breakdown, high temperature, no fear of combustion, no electromagnetic interference and noise, simple structure, easy production, and mass production. In some fields, it has become an ideal replacement component for electromagnetic transformers. This type of transformer is used for switch converters, laptops, neon light drivers, etc.

Design principle: the Ultrasonic welding transducer can offset the expansion stress of piezoelectric ceramics by applying prestress to achieve large amplitude high-frequency vibration. The welding transducer requires large instantaneous power, high requirements for materials and processes, and belongs to a large function ultrasonic super energy. Usually, a high power and large amplitude vibration system is formed through the amplitude horn and working head to complete ultrasonic welding of materials such as plastics, metals, textiles, etc. Ultrasonic welding generates high-frequency friction and heat on the contact gap surface of the welded object under pressure through the high-frequency vibration generated by the transducer, so as to achieve the purpose of hot-melt welding.

Ultrasonic welding transducer, also known as welding vibrator, is a high-power transducer working in gaps or pulses, and its power is generally calculated by instantaneous peak power.
