Description

Technical Field

[0001] The present invention relates to the technical field of water cutting devices, in particular to an ultrasonic dynamic automatic water cutting device based on a resonance impedance model. Background Art

[0002] The ultrasonic dynamic automatic water cutting device is an intelligent device that uses ultrasonic energy to achieve efficient and precise water cutting. It is mainly used in the separation or cutting scenarios of liquid media in industrial production, such as water cutting and emulsion separation. Its core principle is to convert electrical energy into high-frequency mechanical vibrations through ultrasonic transducers, forming local high-intensity shear forces in the liquid, causing water molecules or droplets to quickly break and separate. The device is equipped with a dynamic control system that can monitor parameters such as liquid level and flow rate in real time, and automatically adjust the ultrasonic power and action time to ensure that the water cutting process is stable and efficient. The device has the characteristics of non-contact cutting, low energy consumption, high precision, and no thermal damage. It is suitable for sensitive materials or precision processes. Compared with traditional mechanical water cutting or hot cutting technology, the ultrasonic dynamic automatic water cutting device can significantly improve production efficiency and product quality, reduce consumables loss, and is an important equipment for modern industrial intelligent upgrades.

[0003] The resonant impedance model is an important tool for analyzing the coupling between the electrical and mechanical properties of a vibrating system in a resonant state. Based on electromechanical analogy theory, it equates a mechanical vibration system, such as mass, spring, and damping, to an RLC circuit. The system's frequency response is described through impedance characteristics. In the model, mechanical mass corresponds to inductance, elastic stiffness corresponds to the inverse of capacitance, the damping coefficient corresponds to resistance, and the resonant frequency is equivalent to the LC resonant frequency. This model can quantitatively analyze the system's impedance peak, bandwidth, and energy loss at resonance. It is widely used in acoustic device design, mechanical vibration control, structural health monitoring, and other fields. For example, in loudspeaker design, optimizing diaphragm parameters using the resonant impedance model can improve sound wave radiation efficiency. In bridge engineering, analyzing the resonant response through the model can mitigate the risk of structural resonance.

[0004] In the existing water cutting devices, such as an intelligent automatic water cutting device with application number 202120144685.2, its technical solution is: it includes a water diversion mechanism, the upper end of the water diversion mechanism is detachably connected to a sealing flange by bolts, the upper end of the sealing flange is fixedly connected to a pushing mechanism, and the lower end of the pushing mechanism is movably inserted and connected in the water diversion mechanism, the lower right part of the outer surface of the water diversion mechanism is fixedly inserted and connected with a liquid inlet pipe, the lower left part of the outer surface of the water diversion mechanism is fixedly inserted and connected with a liquid oil discharge pipe, the middle part of the lower end of the water diversion mechanism is fixedly connected with a fixed bin, the left side of the outer surface of the fixed bin is fixedly inserted and connected with a flow sensor, the lower end of the fixed bin is fixedly connected with a bending pipe, and the right end of the bending pipe is fixedly connected with a residual liquid processing device, but the cutting parameters of the traditional device are fixed, and it is difficult to adapt to changes in different liquid level heights, fluid viscosity or cutting amount. When the liquid level in the storage tank is low or the fluid viscosity is high, the mechanical cutting efficiency is significantly reduced, and even blockage or jamming occurs.
