Abstract

The invention relates to the technical field of magnesium plate production, in particular to a method and mold device used for producing wide-width magnesium plates. The mold device used for producingthe wide-width magnesium plates at least comprises an inner barrel which is provided with a blank material machining cavity; the blank material machining cavity comprises a mold cavity, a forward extruding area, a multi-corner equal-diameter angle extruding area and a magnesium plate outlet which sequentially communicate with one another from top to bottom; the forward extruding area is of a big-end-up conical structure; and the multi-corner equal-diameter angle extruding area is provided with at least two corners. According to the method and mold device used for producing the wide-width magnesium plates, the two manners of forward extruding and multi-corner equal-diameter angle extruding are combined, wide-width magnesium alloy medium thick plates and thin plates with high plasticity canbe directly produced in one machining travel, the continuity production requirement of the magnesium plates is met, the production efficiency is improved, and the rate of finished products of the magnesium alloy plates and the finished product quality are improved.

Description

technical field [0001] The invention relates to the technical field of magnesium plate production, in particular to a method and a mold device for producing wide-width magnesium plates. Background technique [0002] Magnesium alloy is the lightest metal structural material in practical application. It has a series of advantages such as light specific gravity, high specific strength and specific stiffness, good damping, thermal conductivity, and electromagnetic shielding performance. Therefore, it is widely used in the automotive industry, communication electronics industry and aerospace industry. And other fields are being increasingly widely used, and it is recognized as the most promising new material industry in the 21st century. However, due to the hexagonal close-packed crystal structure of magnesium alloys, only basal plane slip and cone twinning can start plastic deformation below 200 °C, so magnesium alloys have poor room temperature plasticity. The commonly used pr...
