Multiple 28Khz Ultrasonic Spot Welding Machine for Auto Tail Fins

Description:

Robot soundproof spot welding, only requires one robot, one set of bottom mold tooling, and one set of ultrasonic components. The advantage of robotic soundproof cotton welding is that it can match multiple soundproof cotton products. It is only necessary to change the bottom mold tooling and robot program to improve the welding efficiency, and you can increase the robot, The disadvantage is that the one-time cost is relatively high.

Specifications:

The use of ultrasonic technology can replace past production of flux, adhesives, buckles or other mechanical fixation, thereby improving the production efficiency and reduce costs. Thus, the ultrasonic welding machine is suitable for auto mudguard welding.

Advantages and Disadvantages of Ultrasonic in Auto Industry.

Advantages:

• Application in riveting, forming and welding
• Light weight, easy to take, easy to operate (handheld)
• Equipped with welding timer
• Easty to set time welding
• Equipped with an overload protection circuit( Voltage, current, phase, temperature, output)
• FET power output
• Automatic resonance
• Maintain the amplitude function automatically
• Starting: achieving maximum power with 105msec

Disadvantages:
Limitation of measure, shape and material.(ultrasonic welding for PP, PC, ABS, PA, PS, AMMA plastic).

Different Applications in Plastic Welding

• Ultrasonic welding: ultrasonic vibration with ultrasonic welding mould, the ultrasonic welding energy conduction to the plastic surface, resulting in local temperature, so that the plastic surface melting. Under the pressure of the ultrasonic hand, so to weld plastic, beautiful, strong effect.
• Ultrasonic implants: the nut screws or other metal into plastic work piece. Ultrasonic energy through the ultrasound machine will be transmitted to the metal. The high-speed vibration and heat, the pressure in the ultrasound machine to make metal objects embedded directly into the plastic inside.
• Ultrasonic riveting: the nature of metal and plastic or two different plastic bonding together, can make use of ultrasonic riveting machine, so that the weldment hard brittle, beautiful, strong.

Principle of Soundproof Barriers Spot Welding:
When the ultrasonic role in the thermoplastic plastic contact surface, it will generate tens of thousands of times per second, high frequency vibration, this high-frequency vibration, ultrasonic energy through the ultrasonic wave transmitted to the mold to ultrasonic welding material surface, it will produce high-temperature materials. Plastic contact surface resulting in rapid melting, coupled with stress, it blend and

Components:

Components of Ultrasonic Spot Welding (Horn, Booster and Transducer)
They can amplify the amplitude at a particular ratio step by step. For example, the transducer amplitude is 6mm, the booster can amplify it triply to 18mm, and then the horn can make it to 36mm. However, the work life of horn would be shortened with the amplification of amplitude. The required amplitude differs with the welding material.
There are three common horn material:
Titanium
high price, excellent performance good toughness and low loss, difficult to be processed;
Its amplitude can reach to 60mm.
Aluminum
low price, fast loss, easy to be processed;
Its highest amplitude less than 300mm.
Steel
too hard to be made as horn;
its highest amplitude less than 25mm;
It is suitable for cutting but the blowpipe need to be added in for its cooling.

FAQ:

1. What is ultrasonic puncture welding?

Ultrasonic puncture welding is only one kind of ultrasonic welding. It belongs to energy welding or destructive welding. It is widely used in auto industry.

2.How to use ultrasonic puncture welding technology?

It was decided by product material, best of same material, or a mixture of materials and other materials. It depends on whether the ultrasonic wave of two kinds material can be fused. You can send the material to try to test.

3.How to design ultrasonic puncture welding?

Usually it is up and down welding. The characteristics of puncture welding, there will certainly be a scar on one side, the other side may not be seen. Many customers are concerned about material issues and also they care about how to design. There are some differences in the products of different ultrasonic puncture welding.

4.What is the ultrasonic welding machine of mud guard and soundproof cotton?

The ultrasonic welding machine of mud guard and Soundproof cotton, the ultrasonic technology is used to weld the two cotton with ultrasonic puncture technology, which is used to weld the auto wheel cover and replace the original binding process. The ultrasonic welding is stable, and the sound insulation effect of loading test meets the standard.Front and rear wheel covers also need ultrasonic welding, you can use a handheld ultrasonic welding machine for welding, also can use multi-head ultrasonic welding or robot welding if large quantity, compared to handheld ultrasonic welding machine, it is low cost and durable.

5.What is the ultrasonic hot riveting welding machine of car carpet soundproof cotton

The ultrasonic hot riveting welding machine of car carpet soundproof cotton is known as car carpet pedal plastic column hot melt welding equipment, it is an automatic welding equipment combining ultrasonic and hot riveting process. The cotton felt is welded by the ultrasonic technology, and the plastic column is riveted by hot riveting technology. The cotton felt is welded by the ultrasonic mother welding head, the cotton felt and the foot pedal are welded firmly, use the advanced ultrasonic generator, controlled by Siemens PLC and the touch screen, the SMC cylinder element and so on.
