A continuous and rapid preparation device for semi-solid slurry of automobile aluminum alloy wheels

Abstract

A device for continuous and rapid preparation of semi-solid slurry for aluminum alloy wheels of automobiles. Stirring equipment and die-casting machine (or die forging machine) are distributed around the circle centered on the intelligent power-assist arm. In the material chamber, take a certain amount of aluminum liquid by leaving aside the oxide film on the liquid surface, then transfer it to the bottom of the graphite tube of the slurry rapid stirring device, insert the graphite tube into the slurry in the central area of ​​the slurry transfer crucible, and turn on the electromagnetic stirrer in the graphite tube Electromagnetic stirring is performed with the electromagnetic stirrer on the periphery of the slurry transfer crucible, and the stirred slurry is quickly transferred to the die-casting machine (or die forging machine) for production. The technical solution can realize the continuous and rapid preparation and transfer of semi-solid slurry, and the quality of the slurry is stable, which is of great significance for the semi-solid production of automobile aluminum alloy wheels.

Description

technical field [0001] The invention relates to the technical field of semi-solid forming, in particular to a continuous and rapid preparation device for semi-solid slurry for aluminum alloy wheels of automobiles. Background technique [0002] In 2010, the annual demand for automobile wheels in the world has reached 600 million pieces, of which aluminum wheels account for about 65%. The most important link in the manufacture of aluminum wheels is the forming method. At present, the main forming methods include low-pressure casting, gravity casting, squeeze casting, differential pressure casting, forging, etc. More than 95% of my country's gravity casting and low-pressure casting. In the early 1970s, Professor M.C.Flemings and Dr. D.B.Spencer of the Massachusetts Institute of Technology first proposed a new method of metal forming, which is to process and prepare metals or alloys in the temperature range between solidus and liquidus. A new process for near-net forming, the m...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the factors such as improper solid-liquid ratio of the slurry, large size of solid particles in the slurry, uneven distribution of solid particles in the slurry, etc. The lack of loose castings, shrinkage cavities, cold scars, under-casting, cold shuts, etc., provides a continuous and rapid preparation device for semi-solid slurry for automotive aluminum alloy wheels
