Wide magnesium alloy ultra-thin plate continuous extrusion device and method

Abstract

The invention discloses a wide magnesium alloy ultra-thin plate continuous extrusion device, which comprises an extrusion device, a continuous rolling plate device and a leveling device, wherein the extrusion device comprises an extrusion barrel and a W-shaped extrusion female die; a W-shaped gap is formed on the W-shaped extrusion female die; the continuous rolling plate device consists of a plurality of groups of rolling plate transfer rollers; each group of rolling plate transfer rollers consist of an upper rolling plate roller and a lower rolling plate roller; a W-shaped protrusion is formed on the upper rolling plate roller; a W-shaped groove is formed on the lower rolling plate roller; the leveling device consists of a plurality of groups of leveling rollers; each group of leveling rollers consist of an upper leveling roller and a lower leveling roller; the upper leveling roller and the lower leveling roller are cylindrical; the continuous rolling plate device is positioned between the extrusion device and the leveling device; and rolling surface curves tend to be flat in turn. Due to a continuous extrusion, rolling plate, leveling or continuous extrusion, rolling plate, rolling, leveling and rolling process, a magnesium alloy ultra-thin plate is continuously deformed and molded at one time, and the plate has bright and clean surface and dense internal structure.
