Rotary vibration coupling stirring device for preparing semi-solid slurry

Abstract

The invention discloses a rotary vibration coupling stirring device for preparing semi-solid slurry. The rotary vibration coupling stirring device comprises a first power system, a stirring vibrationdevice, a stirring disc inner layer stirring device, a material barrel, a stirring rotary vibration device, a material barrel rotary vibration device, a second power system and a support. According tothe rotary vibration coupling stirring device for preparing the semi-solid slurry, the stirring vibration device can enable a stirring rod to realize reciprocating motion in the Y direction while stirring, so that axial shearing force is generated; when the stirring rotary vibration device is used for stirring slurry in the stirring rod, reciprocating motion is generated in the X direction to form radial shear force; the material barrel rotary vibration device can drive the material barrel to rotate and generate reciprocating motion in the X direction and the Y direction at the same time, sothat the whole slurry rotates and vibrates; and under the combined action of the three devices as well as the local and overall organic combination, the slurry is stirred more thoroughly, and the efficiency and quality of preparing the semi-solid slurry of the metal and the alloy are improved.

Description

technical field [0001] The invention belongs to the technical field of metal semi-solid processing and molding, and in particular relates to a rotational vibration coupling stirring device for preparing semi-solid slurry. Background technique [0002] After nearly 50 years of development and exploration, the semi-solid forming technology of new aluminum alloy slurry has entered the stage of industrial application from the era of theoretical exploration. However, in the semi-solid metal forming process, how to obtain a semi-solid metal slurry with uniform crystal grains and high sphericity has become a key issue in the semi-solid processing technology. The mechanical stirring method in the current preparation method of semi-solid metal materials has a simple device and can control process parameters, such as stirring temperature, stirring speed and cooling speed, but it also has corresponding limitations at the same time, and it is easy to produce defects such as air mixing. ...

AI Technical Summary

Problems solved by technology

The mechanical stirring method in the current preparation method of semi-solid metal materials has a simple device and can control process parameters, such as stirring temperature, stirring speed and cooling speed, but there are corresponding limitations at the same time, and it is easy to produce defects such as air mixing. The mixer is in direct contact with the alloy melt, which is prone to pollution, and there is a dead zone between the mixer and the container, which makes the mixing insufficient and affects the quality of the mixing
