AI Technical Summary

Technical Problem

The ultrasonic wave distribution in the metal molten pool in the existing ultrasonic melting and casting equipment is uneven, which affects the processing effect of metal castings.

Method used

The metal melt control system using phased array ultrasound obtains ultrasonic pretreatment information through the data acquisition module, which is converted into a voltage square wave signal by the main control module, and converted into a dynamic ultrasonic signal by the transducer amplitude module. The ultrasonic beam is then emitted to the metal melt pool in the form of an array to achieve uniform distribution of the dynamic ultrasonic signal.

Benefits of technology

It achieves uniform distribution of ultrasonic signals in the molten metal pool, improves the processing efficiency and quality of metal castings, breaks through the frequency limitation of a single sound source, and enhances the processing effect of cavitation effect on the metal melt.

Abstract

Embodiments of the present invention relate to a phased array ultrasonic metal melt control system, method, and device, the system comprising a data acquisition module, a main control module, a transducer and amplitude modulation module, and a metal melting module. The phased array ultrasonic metal melt control system obtains dynamic ultrasonic signals, which are used to control the metal melt pool in ultrasonic melting and casting equipment to melt processing components, through the data acquisition module, the main control module, and the transducer and amplitude modulation module. The dynamic ultrasonic signals can be transmitted to the metal melt pool in an array through the transducer and amplitude modulation module, so that the dynamic ultrasonic signals are evenly distributed in the metal melt pool, facilitating the processing of metal castings in the metal melt pool. Due to the array's good fault tolerance, the efficiency of metal processing using ultrasonic signals is greatly improved, resolving the technical problem of uneven ultrasonic distribution in the metal melt pool in existing ultrasonic melting and casting equipment, which is unfavorable for metal casting processing.
