Repair Ultrasonic Converter 20Khz 2000w CJ20 for Branson Welding Machine

Description:

The converter is aptly named because it receives electrical energy from the power supply and converts it into mechanical vibrations. Branson CJ-20 converter (101-135-059) replacement used in all 20KHz 2000, 2000X and DCX series IW, actuator and assembly stand systems that delivers rugged quality and superior value.

Ultrasonic transducers are devices that convert electrical energy into mechanical energy ultrasonic waves. The most mature and reliable device that converts electrical energy and acoustic energy by piezoelectric effect is called piezoelectric transducer.

Influence of processing conditions of plastic parts on ultrasonic welding:

Different processing forms of plastic parts, such as injection molding, extrusion or blow molding, and different processing conditions will form factors that have an effect on ultrasonic welding.
A: Humidity defect: Humidity defects are generally formed during the process of making streaks or loose plastic parts. Humidity defects attenuate useful energy during welding, so that the sealing position seeps and lengthens the welding time, so the plastic parts with high humidity should be made before welding. Drying treatment. Such as polyoxymethylene.
B: The impact of the injection molding process:
Adjustments to the parameters of the injection molding process can cause the following defects:
1 Dimensional change (shrinkage, bending deformation)
2 weight change
3 surface damage
4 poor unity
C: Storage period: After plastic parts are injection-molded, they are usually placed for at least 24 hours before welding 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 plastic
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.
E: release agent and impurities
Release agents and impurities have a certain effect on ultrasonic welding. Although ultrasonic waves can shake off solvents, impurities, etc. on the machined surface, they should be removed as much as possible for sealing or high strength. In some cases, it is necessary to clean the plastic parts first.
