Suspension cone bucket type semi-solid metal slurry preparation and conveyor device

Abstract

Disclosed is a suspending tapered bucket type semisolid metal slurry preparation and conveying apparatus, which belongs to the technique field semisolid metal machining. The apparatus comprises an adjustable speed motor 1, an elevating mechanism 2, an air pipe 3, a connecting device 4, a press-casting machine injection chamber 5, an air port 6, a transmission bevel gear 7, a mandrel 8, a coupling 9, an air pipe 10, a pony ladle 11, an inner tapered bucket 12, an outer tapered bucket 13, a heating and cooling element 14, a flanged disc 15 and the like. When in semisolid metal slurry preparation, according to the shearing deformation principle, the purpose of forming fine and even semisolid metal slurry can be achieved through the intense shearing function when the liquid state metal passes through gaps between the rotating inner tapered bucket and the outer tapered bucket which are inscribed with specific grooves, and the prepared semisolid metal slurry is conveyed to the press-casting machine injection chamber through the connecting device to realize the rheological die-casting molding. The invention has the advantages of: simple and compact equipment structure and light weight; high temperature control precision; convenient and reliable operation, and easy realization from semisolid metal slurry preparation, conveying to die-casting molding; and convenient maintenance and repair and industrialized continuous production.

Description

technical field [0001] The invention belongs to the technical field of semi-solid metal processing, and provides a suspended cone bucket type semi-solid metal slurry preparation and delivery device. Background technique [0002] Semi-solid metal processing technology is to perform strong shearing and stirring on the solidifying metal or alloy, or control the solid-liquid temperature range to obtain a solid-liquid mixed slurry in which a certain solid-phase component is evenly suspended in the liquid metal mother liquor Material (solid phase components can even reach 60%), the method of preparing and forming metal slurry that is neither completely liquid nor completely solid is called semi-solid metal processing technology. This technology breaks the traditional dendritic solidification mode. The metal slurry contains both a certain volume ratio of spherical primary solid phase and a certain ratio of liquid phase. Therefore, semi-solid metal forming has its unique and obvious...
