40Khz Easy Operation Ultrasonic Spot Welding Machine With Automatic Resonance

Description:

Ultrasonic spot welding machine used in the plastics industry has become more and more popular all over the world. The working principle of ultrasonic spot welding machine is to use the high voltage and high frequency signals generated by the generator to convert into high frequency vibration through the energy conversion system and add it to the workpiece of plastic products. Above, the friction between the surface of the workpiece and the intrinsic molecules is generated by vibration at the interface. When the temperature reaches the melting point of the workpiece, the interface of the workpiece melts rapidly, and then the gap between the interfaces is filled. When the vibration stops, the workpiece is cooled under a certain pressure. , to achieve the perfect welding. Ultrasonic welding is an advanced process for joining plastic parts with its advantages of fastness, cleanliness and safety. This technology can replace the solvents, adhesives, fasteners or other mechanical fixing methods required in the past. This technology can improve production efficiency and reduce costs.

Specifications:

Two Types of Horn:

Gun type: in accordance with the shape design of human body engineering, ultrasonic start switch is located on the trigger, easy to grasp and use the welding operation, especially suitable for horizontal or vertical.

Cylinder type: for the appearance of design straight, ultrasonic start switch is located outside the cylinder, easy welding and hand carried, can also be installed between the on machine, welding operation for each direction.

Types of Ultrasonic 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 Ultrasonic Car Bumper Riveting Spot Welder:

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 coagulation, so that to achieve the purpose of ultrasonic welding.

Condition of Ultrasonic Welding:

Ultrasonic automotive plastics as the condition of ultrasonic welding, the most important is the time to apply welding energy (vibration, welding time) length and pressure, of course, other conditions are also very important. Welding temperature ultrasonic welding material viscosity flow temperature. Otherwise the material will not melt.

Three Common Horn Material:

1.Titanium

High price, excellent performance good toughness and low loss, difficult to be processed;

Its amplitude can reach to 60mm.

2. Aluminum

Low price, fast loss, easy to be processed;

Its highest amplitude less than 300mm.

3. 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.
