Replacing Traditional Binding Process by Ultrasonic Technology for Auto Wheel Cover

Replacing Traditional Binding Process by Ultrasonic Technology for Auto Wheel Cover 

Description: 

Auto right front wheel cover outer plate assembly ultrasonic puncture welding machine also known as car front and rear door trim panel assembly ultrasonic welding tooling. It is the use of ultrasonic technology to weld the car wheel cover trim components, use PLC to control the touch screen display parameters, and use a multihead ultrasonic welding machine to weld once.

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. 

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 if thickness. Many customers are concerned about material issues and also they care about how to design. Here we share the actual ultrasonic puncture welding cases. There are some differences in the products of different ultrasonic puncture welding. The content is for reference only.

Specifications:

Gun and Cylinder Type 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.

Principle of Soundproof Barriers Spot Welding:

The ultrasonic puncture welding of the right front wheel cover outer plate assembly of the auto is divided into single point and multihead welding. Some welding a point, some welding two points at the same time, according to the design of the product to see whether each solder point can be soldered.

Components:

Components of Ultrasonic 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.

Applications In Automobile:

Ultrasonic Spot Welding is mainly used in automotive interior parts. Ultrasonic spot welding in sound-proof cotton of engine cover, trunk and wheel casing, and hallstand felt. Ultrasonic Riveting Welding can be used in automobile air-conditioning outlet welding, car rear view mirror, car door handles, hand car door and so on.

Automotive plastic parts are mostly welded in non-standard ultrasonic welding equipment, long multi-station design, with PCL program control and LCD operation, large automotive complex workpiece welding, including different directions of the welding surface, in multiple locations.
