Principle of Welding
The welding principle is: the use of an ultrasonic transducer to convert high-frequency electrical energy into mechanical vibration energy, and then transfer to the contact surface of the weldment through the ultrasonic welding mold. Mechanical vibration will generate high temperature, and when the melting point of the weldment is reached, the plastic part will melt. The ultrasonic welding head applies a certain pressure again, and when the mechanical vibration stops, the plastic parts are rapidly cooled and solidified, and the specific shape designed by the ultrasonic welding head and the bottom mold will be formed. And to achieve a perfect welding effect, the welding strength is the same as the raw material. Ultrasonic welding machine: Application in the automobile industry: manufacturing body plastic parts, automobile doors, automobile instruments, lights and mirrors, sun visors, interior parts, filters, reflective materials, reflective spikes, bumpers, cables , Plastic filters for motorcycles, radiators, brake fluid tanks, oil cups, water tanks, fuel tanks, air ducts, exhaust gas purifiers, tray filter plates, bicycle parts, bicycle tail lights, electric bicycle parts, etc.
1. Model: JL-1542
1.1 Ultrasonic power: rated power 4200W, high power 4600W
1.2, ultrasonic frequency 15KHZ
1.3. Power supply: AC220 V 50 HZ
2. Equipment operation description:
This machine is a single-head integrated ultrasonic welding machine, and the ultrasonic generator is connected with the host by a cable, which avoids malfunctions caused by vibration during work.
3. Basic principles and characteristics of ultrasonic welding:
The 15KHZ high-voltage and high-frequency electrical signal is generated by the ultrasonic generator, which is converted into the mechanical oscillation of the same frequency through the piezoelectric inverse effect of the transducer, and acts on the plastic product workpiece in the form of audio longitudinal wave, passing the surface of the workpiece and the inner molecule When the temperature reaches the melting point of the workpiece itself, the interface of the workpiece melts quickly, and then fills the gap between the interfaces. When the vibration stops, the workpiece is cooled and set under a certain pressure at the same time. Perfect welding.
Fourth, the main structure of the equipment and component brands:
4.1 Transduction system: It adopts Japanese original chip transducer and Japanese ace steel horn, which is strong in power, sturdy and wear-resistant, and its power is 20% higher than the equivalent domestic transducer system.
4.2 Pneumatic components: large-diameter cylinder Φ63*80MM-20, five-way solenoid valve, stable up and down operation, good cushioning effect, eliminating the impact force of the welding head on the workpiece and the recoil force on the transducer, which is more conducive to welding more precise Workpiece and effective protection of piezoelectric ceramics.
4.3 This machine is equipped with a precise fine-tuning mechanism, the fine-tuning distance can be as precise as 0.02mm, and there is an instrument indication. The height of the fuselage and the descending distance of the welding head have scale indications, with an accuracy of 1.0mm;
4.3 Frame: Unique rectangular column design, higher mechanical strength, effectively avoiding the phenomenon of backwards during work, frame sheet metal, etc. are all processed by laser cutting machine, CNC shearing and bending machine to ensure the whole machine The assembly is well-matched, the whole machine is all painted, with good adhesion, no falling off, and beautiful appearance.
4.4. Motion structure: The equipment adopts Taiwan famous brand linear slide, which has high precision (it can not be compared with traditional guide rod with linear bearing) and is strong and wear-resistant, so that the welding head can drop more smoothly without deviation., more Conducive to welding more precise products.
4.5 Balance mechanism: The transducer assembly can be rotated at will, and the transducer assembly is equipped with a horizontal adjustable structure, and the worktable is equipped with an adjustable structure. The two debugging structures make the debugging mold more convenient and quick, easy to operate, easy to learn and understand.
4.6 Electrical system: assembly of a full set of high-quality imported components, improved design of the power amplifier, and increased amplification components to share the load,
Reduce the temperature rise of the transistor and reduce the damage rate. There is no program control board design. The mechanical time dial switch is replaced by the Japanese OMRON time relay, and the time control is more accurate and reliable.
