Continuous rapid preparing device of semi-solid slurry of automobile aluminum alloy wheels

Abstract

The invention discloses a continuous repaid repairing device of semi-solid slurry of automobile aluminum alloy wheels. The device is composed of a continuous melting refining purification furnace, a slurry rapid stirring device, a slurry transfer crucible and an intelligent assistance arm. The material continuous refining purification furnace, the slurry rapid stirring device and die-casting machines (or die forging machines) are distributed on the circumference of the circle with the intelligent assistance arm as the center; the slurry transfer crucible is mounted on the intelligent assistance arm and inputs the motion program of the intelligent assistance arm to a computer; according to the slurry transfer crucible, in a material taking chamber, a liquid face oxide thin film is put aside, a certain amount of molten aluminum is taken, and then is transferred to the position below a graphite pipe of the slurry rapid stirring device, the graphite pipe is inserted into slurry in the center area of the slurry transfer crucible, and an electromagnetic stirrer in the graphite pipe and an electromagnetic stirrer on the periphery of the slurry transfer crucible are started to carry out electromagnetic stirring; the slurry stirred to be qualified is rapidly transferred to the die-casting machines (or die forging machines) for production. According to the technical scheme, semi-solid slurry continuous and rapid preparing and transferring can be achieved, the slurry is stable in quality, and the device is of great significance in semi-solid production of the 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...
