Application of sub-welding head in welding machine for automobile door panel
The application of ultrasonic riveting in automotive interior parts is very extensive. Such as car door panel welding machine, main body welding machine under instrument panel, instrument panel, glove box, central armrest, engine hood, air duct, column, ceiling, coat rack, left and right luggage compartment trim, bumper and other welding equipment will be used .
In riveting, generally one welding unit corresponds to one welding head. If the two solder joints are on the same plane, and the distance is not more than 5CM, then you can consider using the sub-mother welding head. What is the sub-mother welding head? The sub-head welding head is to connect N small welding heads under a large welding head, and the length of the small welding head is a multiple relationship with the large welding head. The application of sub-welding heads can improve welding efficiency and reduce the number of transducers and amplifiers. In the selection of materials, the parent welding head generally uses 7075 aluminum alloy, and the child welding head generally uses titanium alloy.
The design and production of ultrasonic sub-welding heads for automobile door panel welding machines are very important. You may often think that the design and production of ultrasonic molds must be very simple. Don't be misled. When using an improperly processed or untuned welding head, it will bring expensive losses to your production-it will destroy the welding effect, and even more serious will directly cause the transducer or Damage to the device. Therefore, the design of an ultrasonic mold is by no means as simple as its shape. On the contrary, it requires a lot of professional knowledge and skills-how to ensure that the welding head can work most economically? How to ensure that the welding head can effectively transmit the mechanical vibration energy converted by the transducer to the workpiece, forming a continuous and stable welding, our engineers have fully considered each link.
