Ultrasonic Copper Wire Welding Machine

The four materials on the market for ultrasonic welding are gold, silver, copper and aluminum. The specific process of ultrasonic copper wire welding machine: the aluminum wire is placed under the indenter, and the indenter presses the copper wire on the connecting surface at a certain speed. When the contact pressure between the copper wire and the connecting surface is stable, the ultrasonic vibration is activated for about several hundred milliseconds. The ultrasonic vibration frequency of ultrasonic copper wire welding machine is in the range of 60kHz-100kHz. For aluminum wire, 60kHz is commonly used. The ultrasonic vibration is transmitted to the aluminum wire and the connecting surface through the indenter. Soften the contact surface between the two, under the action of pressure, the atoms share electrons to form a connection. In the whole process, the temperature does not exceed 80 or 100 ℃, which is cold welding (no melting stage), and no subsequent cleaning treatment is required.

Parameters

The material of ultrasonic welding horn of Ultrasonic Copper Wire Welding Machine

Current ultrasonic mold material:

1, Titanium alloy (7075, 2024, 6061-T651): 7075: generally used in vibration system and HORN manufacturing, with high hardness, strong thermal conductivity and good toughness. 2024: It is generally used in HORN manufacturing, with good toughness, strong thermal conductivity and moderate hardness. It is used for general welding plastic products. 6061: It is generally used for bottom mold manufacturing or HORN with low output, with good toughness and hardness ratio of 2024.

2, SCM8: It is generally used for embedding screws and metal insertion. It has excellent toughness, high hardness, and less heat conduction than 2024.

3, Titanium alloy: generally used for continuous vibration generation, with high toughness, good heat conduction, high hardness and high cost. Current bottom mold fixture material:

1, Aluminum alloy, aluminum titanium alloy: commonly used for metal or plastic products.

2, 45C medium carbon steel: suitable for PVC boxes, bubble shells and other tooth forming fixtures and other hard metals or nonmetals, such as plastic steel, PBT, etc.

3, SS41 iron material: applicable to general metal products or hard nonmetals.

4, Epoxy resin: suitable for plastic products with irregular shape.

5, PUT resin: It is suitable for plastic products that focus on appearance, have low output and short welding time.

6, Bakelite: suitable for general plane welding of plastic products, or ultrasonic vibration plate fixture.
