20k ultrasonic welder for plastic toys

The factors that affect the welding frequency of Ultrasonic Welding Machine is transducer and luffing rods, etc., and some simple changes in them will have a certain impact on the welding effect.
In the application of power ultrasonic technology, the main role of the amplitude rod is two: one is to displace the mechanical vibration or amplify the speed amplitude, or to concentrate the energy on a small radiation surface, that is, the energy gathering effect; Another role is to act as a converter of mechanical impedance, so that the ultrasonic energy is transmitted more efficiently to the load by the ultrasonic transducer.
Manufacturers of Plastic Ultrasonic Welding Machine will calculate and analyze some data to come up with some parts improvement solutions, and strive to produce better ultrasonic plastic molds. In the study of the vibration system of the welding machine, the manufacturer carries out a lot of design schemes, and below we have solved the design of the luffing rod of the Ultrasonic Plastic Welding Machine.
Manufacturers of 20K Ultrasonic Plastic Welder use PRO-E software to establish a three-dimensional model according to the size of the luffing rod, and use frequency analysis tools to analyze the frequency of the luffing rod. It is worth noting that when selecting the ultrasonic welding machine luffing rod material, it is necessary to choose a duralumin type of 2A01 material, the diameter of the small end of the luffing rod should be designed to be 20 mm, and the length should be 128 mm, so that the output end of the luffing rod can get a higher amplitude and vibration speed. By calculating the amplitude of the output of the transducer of the ultrasonic plastic welding machine, and then obtaining the amplification coefficient corresponding to the amplitude, the relationship between the power and amplitude of the ultrasonic wave is obtained through the calculation of the model. Different power requirements for amplitude are not the same, the size of the cross-sectional area of the amplitude rod is also different, and the quality of the ultrasonic plastic mold produced is also different. The frequency value is designed as 20,000 Hz, combined with the elastic modulus and Poisson ratio of the 2A01 material, and the ultrasonic plastic is used to determine whether the diameter and length of the small end of the luffing rod are reasonable.

The above is a description of the design of the ultrasonic plastic welding machine luffing rod, through the description we know that the experts mainly through the establishment of three-dimensional mode, the selection of 2A01 duralumin material, with frequency analysis tools, calculate whether the designed amplitude rod is reasonable. Through this research method, we can continuously test the design scheme of a variety of ultrasonic welding machine luffing rods, so that the vibration amplitude of the welding machine can be studied well, and a better ultrasonic plastic mold can be produced.
