Embodiment 1

[0053] Such as figure 1 with figure 2 As shown, the single sound source multi-directional power ultrasonic metal coagulation device of the present embodiment comprises a metal coagulation device body, and the metal coagulation device body includes a casting mold 4 poured from the top, a waveguide ring 8 sleeved on the periphery of the casting mold 4 and connecting On the waveguide ring 8 and press the multiple horns 5 on the outer wall of the mold 4 from multiple directions, one of the horns 5 is an active horn and is connected with an ultrasonic transducer 6, and the rest are not connected The horn 5 of the ultrasonic transducer 6 is a passive horn, and the distance between the connection points of two adjacent horns 5 on the waveguide ring 8 is an integer multiple of the half-wavelength of the vibration of the ultrasonic transducer 6 A master alloy pool 1 for heating molten alloy solid raw materials and pouring into the casting mold 4 is arranged above the casting mold 4 ....

Embodiment 2

[0078] The difference between this embodiment and Embodiment 1 is that the waveguide ring 8 is a circular waveguide ring, the casting mold 4 is a straight quadrangular prism, and the number of the horns 5 is four and evenly arranged in the waveguide. On the wave ring 8 , four horns 5 are respectively pressed against the four outer walls of the mold 4 . In step 602, the computer 10 drives the ultrasonic transducer motor 7 and each horn motor 12 to rotate through the motor driver 13, so that the ultrasonic transducer motor 7 and the horn motor 12 reach the optimal position, so that multiple horn motors The appropriate specific process for the compression force of the rod 5 to compress the outer wall of the mold 4 is:

[0079] Step 6021, the computer 10 drives the ultrasonic transducer motor 7 and the horn motor 12 opposite to the ultrasonic transducer motor 7 to rotate through the motor driver 13, and adjusts the ultrasonic transducer motor 7 and the horn motor 12 Two respectiv...

Abstract

The invention discloses a single sound source multi-directional power ultrasonic metal solidification device and method. The device includes a metal solidification device body, and the metal solidification device body includes a casting mold, a wave guide ring and a plurality of horns, one of which is It is an active horn and is connected with an ultrasonic transducer; the method includes steps: 1. Install alloy raw materials; 2. Install a metal solidification device body; 3. Install a sound pressure sensor; 4. Master alloy smelting; ; Six, single source multi-directional power ultrasonic metal solidification; seven, unloading castings. The invention can generate relatively uniform vibration in all directions of the casting mold, and solves the problems in the prior art that the phase difference of multiple vibrations varies randomly, the superposition effect of waves in the melt is unstable, and the vibration from the vibration source to the melt cannot be guaranteed. The problem of delivering effects.

Description

technical field [0001] The invention belongs to the field of advanced material preparation and processing, and in particular relates to a single sound source multidirectional power ultrasonic metal solidification device and method. Background technique [0002] Casting is the process of gradual solidification of metal melt in the cavity. It is one of the important metal forming technologies. Complex parts of the device. Specific materials involve aluminum alloys, magnesium alloys, copper alloys, nickel-based superalloys, and the like. Continuously improving the performance of castings is of great significance to the development of various industries. [0003] Studies have shown that applying an ultrasonic field during the metal solidification process can use a series of nonlinear effects such as cavitation and acoustic flow generated by ultrasonic waves in the liquid phase, which can significantly affect the nucleation, heat and solute transport of the metal melt, and can ...
