Rotating and vibrating coupling stirring device for semisolid slurry

Abstract

The invention discloses a rotating and vibrating coupling stirring device for semisolid slurry. The rotating and vibrating coupling stirring device comprises a rack, a first power system, a bucket rotating and vibrating device, a bucket Y-direction vibrating device, a stirring rotating device, a second power system, a double worm gear and worm mechanism, a bucket and a stirring rod. According to the rotating and vibrating coupling stirring device for the semisolid slurry, the stirring rod can reciprocate in the Y direction through a stirring vibration device while stirring is carried out so asto generate axial shearing force; the stirring rod can reciprocate in the X direction through a stirring rotating and vibrating device while stirring is carried out in the slurry so as to generate radial shearing force; and the bucket rotating and vibrating device can reciprocate in the X direction and the Y direction while the bucket is driven to rotate so as to integrally rotate and vibrate theslurry. Under the combined action of the above three devices, the slurry is stirred more thoroughly under the local and integral organic combination, so that the efficiency and quality of preparing the semisolid slurry of metal and alloys 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 rotary vibration coupling stirring device for semi-solid slurry. Background technique [0002] The new aluminum alloy slurry semi-solid forming technology 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. The direct contact between the mixer and the alloy melt is prone to co...

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
