Magnesium alloy and aluminum alloy semi-solid slurry preparation structure

Abstract

The invention discloses a magnesium alloy and aluminum alloy semi-solid slurry preparation structure, which includes a melting material cylinder, and the other end of the melting material cylinder close to the discharge nozzle is fixed with a splitter cone. The splitter cone includes a splitter cone body and a The tapered feed end and the tapered discharge end at both ends of the cone body. The tapered feed end is provided with a number of feed diversion grooves extending to the splitter cone body starting from the cone tip. The tapered discharge end Starting from its cone tip, there are several discharge diversion grooves extending to the body of the diverter cone. A slit flow path is formed with the inner wall of the melting barrel. The magnesium alloy and aluminum alloy semi-solid slurry preparation structure can smoothly transform the molten material from dendrite to spherulite by adding a splitter cone in the melting material cylinder, which improves the conversion efficiency of the slurry and ensures the formation quality of the semi-solid slurry , so that finer products can be molded, and the molding quality and efficiency can be improved.

Description

technical field [0001] The invention relates to a semi-solid slurry preparation structure, in particular to a magnesium alloy and aluminum alloy semi-solid slurry preparation structure. Background technique [0002] In the 1970s, Flemigs of the Massachusetts Institute of Technology proposed metal semi-solid forming technology. The preparation and forming technology of semi-solid metal paste has attracted widespread attention from all over the world as a new technology. Semi-solid processing is a method of forming by using the characteristics of the metal during the transition from liquid to solid or from fixed to liquid (ie, liquid-solid coexistence). This new forming method combines the strengths of solidification processing and plastic processing. That is, the processing temperature is low, the molding temperature is low, the thermal impact force on the mold is small, and the deformation resistance is smaller than that of the solid state, which is conducive to forming more...

AI Technical Summary

Problems solved by technology

The advantages are simple structure and low manufacturing cost, but the supercooled melt condenses and hangs on the mixer and manipulator, and needs to be disassembled and cleaned after multiple preparations, and the equipment is heavy and difficult to disassemble. At the same time, it is easy to get involved in gas during the stirring process. Mixing into molding equipment greatly affects molding quality

If it is only heated and melted to form a semi-solid slurry, the peripheral slurry will also be easily affected by the external temperature to cool down when the manipulator is filling the material. Due to the low fluidity of the slurry, it will hang on the manipulator after repeated use, and it needs to be cleaned continuously. ,increase workload
