Description
Anything that vibrates will make a sound, and any sound is caused
by vibration. Human ears can only perceive sounds within a certain
range, and this range can be as high as 18000 (18K) Hz. Higher
frequency sound we call it ultrasound. Ultrasonic waves can
generate high-frequency vibrations. Using this vibration, we can
easily weld non-ferrous metals. Ultrasonic wire harness welding
machine is a derivative equipment of ultrasonic metal welding
machine. Mainly used in the welding of copper wire and aluminum
wire such as the welding of automobile wiring harness and
motorcycle wiring harness. So it is often called automobile wire
harness welding machine.
Ultrasonic metal welding uses high-frequency vibration waves to be
transmitted to two metal surfaces to be welded. Under pressure, the
two metal surfaces are rubbed against each other to form a fusion
between molecular layers. Its advantages are rapid, energy-saving,
and fusion. High strength, good electrical conductivity, no sparks,
close to cold processing; the disadvantage is that the welded metal
parts should not be too thick (generally less than or equal to
5mm), the solder joints should not be too large, and they need to
be pressurized. Ultrasonic metal welding was discovered by accident
in the 1830s. At that time, during the current spot welding
electrode plus ultrasonic vibration test, it was found that it
could be welded without current, so the ultrasonic metal cold
welding technology was developed. Although ultrasonic welding was
discovered earlier, its mechanism of action is still not very clear
so far. It is similar to friction welding, but there are
differences. Ultrasonic welding has a short time and the
temperature is lower than recrystallization; it is also different
from pressure welding because the static pressure applied is much
smaller than that of pressure welding. It is generally believed
that in the initial stage of the ultrasonic welding process, the
tangential vibration removes the oxides on the metal surface, and
the protruding part of the rough surface produces repeated
micro-welding and destruction, which increases the contact area and
increases the temperature of the welding zone. High, plastic
deformation occurs at the interface of the weldment. In this way,
under the action of contact pressure, when they approach each other
to the distance at which atomic gravity can act, a solder joint is
formed. The welding time is too long, or the ultrasonic amplitude
is too large, which will reduce the welding strength or even
destroy it.
Features
1. The two objects to be welded are overlapped and joined by
ultrasonic vibration and pressure to form a solid state, the
joining time is short, and the joining part does not produce cast
structure (rough surface) defects;
2. Compared with the method of ultrasonic welding and resistance
welding, the mold life is long, the mold repair and replacement
time is less, and it is easy to realize automation;
3. Ultrasonic welding can be carried out between the same kind of
metal and different kinds of metals, which consumes much less
energy than electric welding;
4. Compared with other pressure welding, ultrasonic welding
requires less pressure, and the deformation amount is less than
10%, while the deformation of the workpiece in cold pressure
welding is 40%-90%;
5. Ultrasonic welding does not require pre-treatment of the welded
surface and post-weld treatment like other welding;
6. Ultrasonic welding can minimize the temperature effect of the
material (the temperature of the welding zone does not exceed 50%
of the absolute melting temperature of the welded metal), so as not
to change the metal structure, so it is very suitable for welding
applications in the electronic field;
