Problems solved by technology

[0002] Magnesium alloy has very low plasticity at room temperature, and its elongation is only about 4-5%, and it is easy to be brittle, so it is difficult to perform plastic processing at room temperature
At present, most of the magnesium alloy casings on the market are made of magnesium chips and magnesium ingots in a high-temperature molten state by casting film molding. Since the magnesium alloys are completely oxidized during production, the magnesium alloy casings have no metallic luster and metallic feel.

Embodiment Construction

[0008] The embodiment of the preparation process of the present invention is as follows:

[0009] First, perform the metal hot die stamping and forming process. The process steps of the metal hot die stamping and forming process are as follows: (1) Place the special forming die on the hydraulic press equipment, and heat the die to 150-280°C; (2) 1) Put the magnesium alloy material directly on the heated forming mold; (3) Press forming. Among them, the stamping process is a key process, and the technical difficulty is relatively high. The failure mode is the rupture at the dangerous end face during stretching.

[0010] The influencing factors of this process are as follows: molding pressure, molding speed, equipment working position, pressure holding time, mold gap, mold corner, mold temperature, material temperature, etc., and there are interactions among various factors. Its failure form is the rupture at the dangerous end face during hot die stamping and forming.

Abstract

The invention relates to a process for processing a magnesium alloy shell. The process is characterized in that the process comprises a metal hot die punch forming process which comprises the following steps: 1. a special forming die is placed on an oil pressure type punching machine, and the die is heated up to a temperature of between 150 and 280 DEG C; 2. the magnesium alloy material is directly placed on the heated forming die; and 3. the punch forming is performed. The process facilitates realization of punch processing production of the magnesium alloy shell so as to improve product quality and production efficiency; moreover, the process also has the advantages of original conception, reasonable design, and big popularization value.

Description

Technical field [0001] The invention relates to a processing technology of a magnesium alloy shell. technical background [0002] Magnesium alloys have very low plasticity at room temperature, and their elongation is only about 4 to 5%, and they are prone to embrittlement, so it is difficult to carry out plastic processing at room temperature. At present, most of the magnesium alloy shells on the market are produced by using magnesium shavings and magnesium ingots in a high-temperature molten state. The magnesium alloy is completely oxidized during the production, resulting in the magnesium alloy shells without metallic luster and metallic feeling. . Summary of the invention [0003] The purpose of the present invention is to provide a magnesium alloy shell processing technology, which is beneficial to realize the stamping processing and production of the magnesium alloy shell, thereby improving product quality and production efficiency. [0004] The method of the present invent...
