Swing stirring device for preparing semisolid slurry and rheoforming equipment

Abstract

The invention provides a swing stirring device for preparing semisolid slurry and rheoforming equipment, and belongs to the field of semisolid metal processing technology. The swing stirring device for preparing the semisolid slurry is composed of swing lifting rods, a swing power device, an alloy melt, fixed stirring rods, a supporting frame, a pony ladle, a stirring chamber, a small sprue, a crucible, heating elements, a die-casting machine, a pressing chamber of the die-casting machine, the semisolid slurry, an injection punch, an extruding machine, a pressing chamber of the extruding machine, an extruding punch and the like. Based on the principles of cooling and stirring, the alloy melt flows in the stirring chamber under the action of the swing stirring rods, the nucleation of the alloy melt is promoted to prepare the semisolid slurry under the stirring action of the fixed stirring rods, and the rheoforming equipment achieves rheoforming easily when matched with forming equipment, such as the die-casting machine, the extruding machine or a forging machine. The swing stirring device for preparing the semisolid slurry and the rheoforming equipment are simple in structure, small in investment, low in production cost, stable and reliable in continuous preparation work, and quite suitable for preparation and forming production of the semisolid metal slurry or blank.

Description

technical field [0001] The invention belongs to the technical field of semi-solid metal processing, and in particular provides a swing stirring device for preparing semi-solid slurry and rheological deformation equipment. Background technique [0002] Since the early 1970s, researchers such as M C Flemings of the Massachusetts Institute of Technology created the concept of metal semi-solid forming, and the preparation and forming technology of semi-solid metal paste has attracted widespread attention from all over the world as a new technology. According to the literature "Behavior of metal alloys in the semisolid state" (M C Flemings, Metall Trans, 1991, 22A: 957-981), "a suspension cone type semi-solid metal slurry preparation and delivery device" (Kang Yonglin, China Patent, 200810114097.3, 2008) and "Semi-solid Processing Theory and Technology of Metal Materials" (monograph: Kang Yonglin, Mao Weimin, Hu Zhuangqi, Science Press, 2004) reported that there are many methods ...

AI Technical Summary

Problems solved by technology

In the equipment of the above technologies, there is no special swing stirring device for preparing semi-solid slurries of light alloys such as magnesium and aluminum, that is, the swing stirring device is not used to cool and stir the alloy melt to promote nucleation
