Abstract

The invention provides a magnesium alloy sheet preparation method and a device for implementing the method. The first aspect of the invention provides a magnesium alloy sheet preparation method whichcomprises the following steps of 1, carrying out extrusion treatment on a magnesium alloy blank to obtain an arc-shaped magnesium alloy sheet with the thickness ranging from 0.6 to 1.0 mm at the extrusion speed of 0.6 to 3.0 mm / s; and 2, flattening the arc-shaped magnesium alloy sheet to obtain a magnesium alloy sheet. According to the magnesium alloy sheet preparation method provided by the invention, waste of magnesium alloy materials caused in the rolling process is avoided, and the problems that in the prior art, the preparation cost is high, and the productivity is low are effectively solved.

Description

technical field [0001] The invention relates to a preparation method and device for a magnesium alloy thin plate, and relates to the technical field of material processing. Background technique [0002] Magnesium alloy has the characteristics of light weight, high strength, antimagnetic, shock resistance and high texture. It has become a business opportunity for 3C product development. With the gradual increase in the use of magnesium alloy sheet for 3C products, it also promotes the preparation process of magnesium alloy sheet Continuous development. [0003] Because the strength of existing extrusion dies cannot bear the high extrusion ratio brought by direct extrusion into thin plates, the existing preparation method is usually to extrude into magnesium alloy thick plates and then roll them into magnesium alloy thin plates. In the preparation process, the magnesium alloy thick plate needs to be rolled many times and repeatedly to obtain the magnesium alloy thin plate tha...
