Description:
ÂÂ
Ultrasonic welding is
a local rapid heating and cooling process. The welding zone cannot
be freely expanded and contracted due to the restraint of the
surrounding workpiece body. After cooling, welding stress and
deformation occur in the weldment. Important products need to
eliminate welding stress after welding and correct welding
deformation. Modern welding techniques have been able to weld welds
with no internal or external defects and mechanical properties
equal to or even higher than the welded joints. The mutual position
of the welded body in space is called the welded joint, and the
strength of the joint is affected by the quality of the weld, and
also related to its geometry, size, stress and working conditions.
The basic form of the joint has docking, lap joint, T-joint
(orthogonal joint) and corner joints.
Ultrasonic plastic
welding machine requirements for welding workpiece materials:
Ultrasonic plastic welding machine has requirements for the
material to be welded. Not all materials can be welded. Some people
think that any material can be welded. This understanding is wrong.
Different materials can be welded directly, some are basic phase
fusion, and some are not phase fusion. The melting point between
the same material is the same, and the principle is that it can be
welded, but when the melting point of the workpiece to be welded is
greater than **0 ° C, it is not suitable for ultrasonic welding.
Because the ultrasonic is instantaneously melting the workpiece
molecules, the judgment is based on within 3 seconds, and the
welding cannot be performed well.
The selection of the output power of the ultrasonic plastic welding
machine: the size of the ultrasonic output power is determined by
the diameter and thickness of the piezoelectric ceramic piece, the
material and the design process. Once the transducer is shaped, the
maximum power is also fixed. Measuring the amount of output energy
is a complicated process. The larger the transducer, the more power
the circuit uses and the higher the output energy. It requires a
fairly complex amplitude meter to accurately measure its
amplitude.

Influence of
plastic parts on ultrasonic welding:
ÂÂ
1. Ultrasonic waves
propagate in plastic parts. Plastic parts absorb or attenuate
ultrasonic energy more or less, which has certain influence on
ultrasonic processing effect. Plastics generally have amorphous
materials, hard rubber and soft according to hardness. The
difference between the glue and the modulus is, in general, the
high-hardness, low-melting plastic ultrasonic processing
performance is superior to the low-hardness, high-melting plastic.
Therefore, this involves the near-far problem of ultrasonic
machining distance.
2. The influence of
the processing conditions of plastic parts on ultrasonic welding,
the different processing forms of plastic parts through injection
molding, extrusion or blow molding, and different processing
conditions will form factors that have certain influence on
ultrasonic welding.
A. Humidity Defect:
Humidity defects are generally formed during the process of making
streaks or loose plastic parts. Humidity defects attenuate energy
during welding, so that the sealing position seeps and lengthens
the welding time. Therefore, the plastic parts with high humidity
should be made before welding. Drying treatment. Such as
polyoxymethylene.
B. The influence of
the injection molding process: The adjustment of the parameters of
the injection molding process will lead to the following defects: 1
dimensional change (shrinkage, bending deformation) 2 weight change
3 surface damage 4 poor uniformity
C. Storage period:
After the plastic parts are injection-molded, they are generally
placed for at least *4 hours before welding, so as to eliminate the
stress and deformation of the plastic parts. Plastic parts that are
molded from amorphous plastics may not meet this
requirement.
D. Recycled plastics:
The strength of recycled plastics is relatively poor, and the
adaptability to ultrasonic welding is also poor. Therefore, if
recycled plastics are used, various design dimensions should be
considered as appropriate.
