1. What is an ultrasonic welding head?
Horn is the generic name of all ultrasonic transmitters, and it is indispensable in ultrasonic welding equipment.
The part. Its function is to couple the ultrasonic wave generated by the transducer to the processed object, because it transmits the ultrasonic wave.
Therefore, the welded joint must work in the resonant state, that is, its natural resonant frequency should match the transducer. The second is the amplitude.
To be uniform, the shape of the end face of the welded joint should be adapted to the shape of the workpiece to be welded.
Material selection of ultrasonic welding head (titanium alloy, magnesium-aluminium alloy, powder metallurgical steel, etc.).
2. Design of ultrasonic welding head:
Ultrasound welding head (ultrasonic welding die), which is directly in contact with the welded object, is responsible for the transmission of ultrasonic vibration energy to the welded object. According to the different ultrasonic frequencies of the source, the welding head with suitable frequencies must be used, and different frequencies can not be mixed. In order to achieve the best welding effect, the welding head must be designed precisely so that it can transmit the vibration energy completely. In addition to choosing the appropriate material according to the characteristics and special requirements of the product, FEM analysis method is often used to assist in evaluating the design of the welding head, so as to improve the product yield and shorten the process for the designer.
The improper processing of welded joints or the use of non-tuned welded joints will damage the welding effect and bring expensive losses to production. Serious damage will directly lead to the damage of transducers or amplifiers.
3. Superiority of Lingke Ultrasound:
A. Welded joints in various forms can be designed and customized according to the appearance and requirements of the products.
B. Frequency is 15 kHz, 20 kHz, 35 kHz and so on.
C. Composite welding head can be made according to the special requirements of special product design.
D. Lingke Ultrasound adopts imported high-order weld joint detection instrument, which can accurately evaluate the quality of weld joint, and matching CNC processing equipment to improve the manufacturing ability of weld joint.
