15KHZ HIGH POWER ULTRASONIC WELDING TRASNDUCER 70MM DIAMERTER
The invention utilizes the vibrational mode of the ultrasonic horn. An ultrasonic welding horn, as any rigid object, has a mode of vibration when excited at a given frequency. In such a mode, the horn is cyclically flexing. Some parts of the horn bend and move, while others move very little or not at all. Within stable limits, an object consistently vibrates in the same mode at a given frequency, and a selected nodal point will have consistent motion. Thus, a nodal point located on the horn at a position having little or no motion will behave consistently each time the horn is vibrated at the same frequency.
A welding horn utilizing the present invention comprises a source for generating vibration at an ultrasonic frequency, a rigid body connected to the source for being vibrated in a mode of vibration, an insert and a coupling means. The body has a nodal point that has relatively less vibration than the rest of the body when the body is vibrating in the mode. Also, the body has a welding edge. The insert is coupled to the body at the nodal point by the coupling means so that the insert is held proximal to the welding edge, but preferably not in contact with the body except by the coupling means.
Naming method:

Description:
The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.
15Khz transducer widely used in high power welding&sealing system.Piezoelectric transducer is the electric charge that accumulates in certain solid materials in response to applied mechanical stress. It is key point of all ultrasonic equipment.The transducer decide the property of the machine.We can supply transducer, also transducer with house and booster.
Strong packaging
