Problems solved by technology

However, because the high-temperature metal tool head is eroded by the metal melt during the working process, it cannot work for a long time; although the ceramic tool head is not easily eroded by the metal melt, the bolt joint is prone to stress concentration under high-frequency vibration conditions. to crack
Therefore, the existing tool heads and connection methods cannot meet the long-term and continuous working conditions of ultrasonic equipment, making this technology always in the laboratory research stage or small-scale application stage, and cannot be applied to industrial production on a large scale

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] see Figure 1 to Figure 3 , a connection structure between the ultrasonic horn 11 and the tool head 12 of the present invention, including: the horn connecting step 111, the tool head connecting flange 121, the clamp 13, the threaded connector 14, the clamp 13 and the tool head connecting flange 121 are fixedly connected; the threaded connector 14 is used to connect the horn connecting step 111 and the clamp 13 .

[0039] The clamp 13 includes an upper clamping body 131. The upper clamping body 131 includes: a first shaft body 1311 that is generally cylindrical and a second shaft body 1312 that is generally cylindrical. The diameter of the first shaft body 1311 is larger than that of the second shaft body. 1312; the first shaft body 1311 is evenly distributed with a number of screw connection holes 13111 passing through it; the upper clamping bo...

Abstract

The invention provides an ultrasonic amplitude transformer-tool head connection structure which comprises an amplitude transformer connection step, a tool head connecting flange, a clamp and a threaded connecting piece, wherein the clamp is fixedly connected with the tool head connecting flange; and the threaded connecting piece is used for connecting the amplitude transformer connection step and the clamp. Compared with correlation techniques, the ceramic tool head is provided with the flange structure, and the steel clamp is used for clamping and fixation, so that the tool head can be directly closely attached to the end surface of the amplitude transformer. The ceramic tool head does not have the stress concentration position, and thus, can not crack due to the structural stress concentration in the working process. The connection structure can enable the ceramic tool head to satisfy the long-time continuous working conditions, so that the ultrasonic melt treatment technique can be industrialized.

Description

【Technical field】 [0001] The invention relates to the technical field of light metal smelting equipment, in particular to a connection structure between an ultrasonic horn and a tool head. 【Background technique】 [0002] In the smelting industry of light metals (such as aluminum alloys, magnesium alloys, etc.), by introducing high-energy ultrasonic waves into the metal melt, it can achieve the effect of degassing, slag removal, and improving the purity of the melt. Crystallization of the grains improves their processability and the quality of the final product. Among them, the tool head that introduces ultrasonic waves into the metal melt is an important part of the ultrasonic equipment. It is generally made of high-temperature metals (such as titanium alloys) or ceramic materials, and is connected to the ultrasonic horn through bolts. However, because the high-temperature metal tool head is eroded by the metal melt during the working process, it cannot work for a long time...
