Slurrying-forming separated aluminium alloy rheological forming method

Abstract

The invention relates to a pulping-shaping detachable aluminum alloy rheologic shaping method, wherein it also provides a quick prepare system of semi-solid alloy pulp. Said method comprises that: preparing heated liquid alloy; preheating mixing pot to 350-400Deg. C; filling heated flux into said semi-solid alloy pulp mixing pot; putting pot into electromagnetic mixer prepare room; starting the mixer to electromagnetically mix; when the mixing is end, taking out the pot, pouring the alloy pulp into the injection cylinder of casting machine; injecting and shaping at 220Deg. C of mould. In said invention, the mixer and shaping device are separated. And it has high efficiency.

Description

technical field [0001] The invention relates to a rheological forming method of an aluminum alloy separated from a rapid preparation system of a semi-solid alloy slurry and a workpiece forming system, and belongs to the technical field of semi-solid alloy forming methods. Background technique [0002] Semi-solid alloy forming technology is usually divided into rheological forming and thixoforming two categories. Due to the application process of semi-solid thixotropic forming technology, it is exposed that the process flow is long, the billet cost is high (the billet cost accounts for about 40% of the part cost), the energy consumption of remelting is high, the billet surface is severely oxidized, and the billet loss is serious during the heating process. (loss as high as 10%), production waste cannot be recycled at the production site and many other problems. Since the 1990s, rheological forming technology has gradually become the key development direction of semi-solid for...
