I. principle of ultrasonic plastic welding machine:
Ultrasonic plastic welding machine through the ultrasonic generator 50/60 Hz current into high frequency electric 15KHZ, 20KHZ, 35KHZ kHz, high-frequency electrical energy by ultrasonic transducer was again converted into mechanical motion by equal frequency conversion, followed by a set of mechanical motion can change the amplitude modulation device to transmit ultrasonic horn. The welding head will receive ultrasonic vibration energy transfer to the junction of the workpiece to be welded. In this region, ultrasonic vibration energy is converted into heat energy by high speed friction method to melt the plastic. Ultrasonic plastic welding machine, the welding time and welding pressure can be adjusted, the amplitude is determined by the transducer and horn.
Two , classification of ultrasonic plastic welding machine:
A, ultrasonic plastic welding machine, referred to as ultrasonic machine, ultrasonic welding machine according to power and performance is mainly divided into:
1, small power, high frequency, such as: QO-2830 hand spot welding machine, hand held hot bead machine, etc.!
2, high-power, high-frequency machine, such as: high precision welding, 28K, 35K, 800W, 1000W desktop, split ultrasonic machine.
3, medium frequency and power of the commonly used models, such as the commonly used 20K, 1500W machines, 20K, 2000W split integral machine
4, low frequency, high power machines, such as 3200W. 4200W one machine, etc.!
B, according to the rack structure, mainly divided into hand-held ultrasonic machine, split ultrasonic plastic welder and an integrated ultrasonic welding machine and automatic turntable type ultrasonic welding machine, etc.
C, according to the mode of operation, the main breaking up type, manual and automatic ultrasonic machine.
Three, ultrasonic plastic welding machine features:
CNC machine tool processing, high precision
New improvement, better performance
The original piezoelectric ceramic transducer has a strong and stable output
Titanium alloy horn, durable
Frequency modulation and frequency automatic compensation circuit
Set up soft starting circuit to avoid damage to the mold
A full set of quality imported components, quality assurance
High welding efficiency, low rate of failure
Four, the use of ultrasonic welding machine:
Ultrasonic welding: ultrasonic vibration with ultrasonic welding mold, the ultrasonic energy transmission to the plastic surface welding, so produce local high temperature, make the plastic surface melting. Under the pressure of the ultrasonic welding machine, make two pieces of plastic to weld, beautiful and strong effect.
Ultrasonic implantation: to place nuts, screws, or other metals into plastic workpieces. The ultrasonic energy is transmitted to metal by an ultrasonic machine. After heat generation by high speed vibration, the metal is directly embedded into the plastic under the pressure of the ultrasonic machine.
Ultrasonic spot welding: welding using miniature ultrasonic machine, two pieces of plastic products into multiple spot welding, or welding the first row of dentate direct pressure on the two plastic parts, so as to achieve the effect of ultrasonic welding.
Ultrasonic riveting: the metal and plastic or two pieces of different nature of plastic joint, can use ultrasonic machine riveting method, make welding parts is not easy to brittle, beautiful and strong.
Ultrasonic molding: the ultrasonic machine is used to fuse plastic workpieces instantaneously. When the plastic is solidified, the metal or other materials can be firmly made of plastics.
Ultrasonic cutting: ultrasonic welding of the mold and the bottom of the special design methods, through ultrasonic transmission to achieve ultrasonic removal of cloth or plastic effect.
