I. The working principle of ultrasonic metal welding machine Ultrasonic metal welding machine is through the high frequency mechanical vibration of the non-ferromagnetic metal material workpiece welding. During the welding process, one workpiece is fixed and the other workpiece is vibrated at a frequency of 20/40kHz in a cyclic manner on its surface, while pressure is applied to the workpiece to form a solid bond between the workpieces, thus achieving the welding effect. The entire welding process can be precisely controlled without generating excess heat on the metal surface and with high welding fastness. The ultrasonic metal welding machine is powered by a crystal function device that converts the current electrical frequency of 50/60Hz into high frequency electrical energy of 20KHz or 40KHz, which is supplied to the ultrasonic welding machine converter. The converter converts the electrical energy into mechanical vibration energy for ultrasound, and the voltage regulator is responsible for transmitting the transformed mechanical energy to the welding head of the ultrasonic welding machine. The welding head of the ultrasonic metal welding machine is an acoustic device that transmits mechanical vibration energy directly to the product to be pressed together, the vibration is transmitted through the welding workpiece to the bonding surface to generate heat energy to melt the plastic, the vibration will stop when the molten material reaches its interface, and the pressure is maintained for a short time to allow the molten material to produce a strong molecular bond when the bonding surface is cured, the whole cycle is usually completed in less than a second, but its welding strength is close to a piece of connected material. Second, the application of ultrasonic welding method 1, fusion method: ultrasonic ultra-high frequency vibration of the welding head under moderate pressure, so that the two pieces of plastic bonding surface friction heat and instantaneous fusion bonding, welding strength can be comparable to the body, the use of suitable workpiece and reasonable interface design, can achieve watertight and airtight, and eliminate the use of auxiliary products brought about by the inconvenience, to achieve efficient and clean fusion. 2, riveting welding method: ultrasonic ultra-high frequency vibration of the welding head, pressing the plastic protruding tip, so that it instantly heats up and melts into the shape of rivets, so that materials of different materials are mechanically riveted together. 3、Embedding: By the transmission of the welding head and the appropriate pressure, the metal parts (such as nuts, screws, etc.) will be instantly squeezed into the reserved plastic holes, fixed in a certain depth, after completion of both tension, torque can be comparable to the strength of the traditional mold molding, can eliminate the injection mold damage and injection of slow disadvantages. 4, molding: This method is similar to the riveting method, the concave welding head pressed against the outer ring of plastic products, the welding head emits ultrasonic ultra-high-frequency vibration will be melted into plastic and wrapped in metal objects to make it fixed, and the appearance of smooth and beautiful, this method is mostly used in electronics, speakers, and cosmetics, such as the fixed lens. 5, spot welding: A, the two pieces of plastic point fusion without pre-designed welding line, to achieve the purpose of fusion. B, the relatively large workpiece, it is not easy to design the welding line of the workpiece for spot welding, and to achieve the fusion effect, can be spot welding more than one point at the same time. 6, cutting and sealing: the use of ultrasonic instantaneous vibration principle of work, the chemical fiber fabric cutting, the advantages of a clean cut without cracking, not pulling.
