Dumbbell Type 15Khz 1500w Ultrasonic Transducer for Welding Application
Description:
As we all know, ultrasonic transducers are the core components of
many ultrasonic devices such as ultrasonic shearing machines,
ultrasonic hot drilling machines, and ultrasonic masking machines.
Their main function is to generate ultrasonic waves and convert
them into mechanical vibration energy.
The main consideration for using ultrasonic transducers is the
matching with the input and output, followed by the mechanical
mounting and mating dimensions. The frequency of the transducer is
relatively straightforward. The frequency refers to a frequency
measured by a transmission line method using a frequency (function)
generator, a millivoltmeter, an oscilloscope, or the like, or a
frequency measured by a network impedance analyzer or the like.
Generally known as the small signal frequency. The customer
connects the ultrasonic transducer to the drive power supply via a
cable, and the actual operating frequency measured when the power
is applied after no load or load. Because the customer matching
circuits are different, the same ultrasonic transducers exhibit
different frequencies at different driving power sources. Such
frequencies cannot be used as a basis for discussion.

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.
