Providing and Repair and Replace High Frequency 28Khz Ultrasonic Transducer Welding System

Description:

Generating regular vibration under the excitation of a suitable electric field by Ultrasonic Transducer, and its amplitude is generally about 8-10 μm. Such amplitude is not enough to directly complete the welding and processing steps. Therefore, the transducer links a properly designed ultrasonic horn, and the amplitude of the ultrasonic wave can be varied within a wide range, as long as the material strength is sufficient, the amplitude can exceed 100 μm.

The transducer is a precision device and should be handled with care. The transducer converts the ultrasonic frequency voltage from the generator into ultrasonic mechanical vibration of the same frequency by an inverse piezoelectric effect. It consists of a number of piezoceramic sheets sandwiched between two metal (usually titanium) blocks. A thin metal plate is formed between the sheet and the sheet to form an electrode. When a sinusoidal electrical signal is supplied to the transducer via the electrodes, the piezoelectric sheet expands and contracts, producing an axial peak-to-peak motion of 15-201 xm.

Ultrasonic transducer parts assembly precautions:

The main parts of the ultrasonic vibration system, such as transducers, horns, tool heads, etc., are connected by a central bolt.

1. Check that the contact surface should be smooth and free of scratches. If there are any scratches, use a metallographic paper with a number of zero or more to lightly polish. It is required to smooth the defect without damaging the flatness of the contact surface.

2. Clean the screws, screw holes and contact surfaces with a volatile, non-corrosive detergent.

3. Thoroughly clean the screws, screw holes and contact surfaces.

4. All connecting screw holes should be perpendicular to the contact surface.

5. Apply a thin layer of butter or Vaseline to the contact surface before tightening. Do not apply to the connecting screws and screw holes.

6. Carefully tighten the two parts. Adjust the appropriate tightening torque according to the specifications of the connecting screws. When possible, tighten it properly.

7. If you loosen the joint surface again, you should not see any scars.

8. The amplitude of the vibration system is evenly distributed by hand, no strange sound, no local severe fever.

9. After re-opening the joint surface after working for a period of time, there should be no signs of oxidation or ablation. Otherwise, the contact here is not good, and the ultrasonic energy is seriously lost here.
