Description

Assembly and processing method of magnesium-lithium alloy components

technical field

The invention relates to an assembly and processing method, in particular to an assembly and processing method of a magnesium-lithium alloy component.

Background technique

At present, various manufacturers are actively developing towards thin and light design of notebook computers, so they usually choose lighter materials as raw materials for manufacturing casings, such as carbon fiber materials, magnesium alloy materials or plastic materials. etc., the above-mentioned materials are used to match the components designed to form the casing, and the characteristics of the selected materials also directly affect the structural strength of the casing of the notebook computer.

In order to meet the requirements of light weight and high-strength structure of notebook computers, as well as the environmental protection concept of recycling and reuse, there are related manufacturers who use magnesium alloy (magnesium alloy) materials to make notebook computer casings. The advantage of magnesium alloy is that it has the same strength and hardness as steel (steel), but its weight is close to that of plastic. Coupled with the advantages of metal ductility, the thickness of the casing made of magnesium alloy can be 0.06-0.08 mm (mm) or even thinner. Compared with the thickness of 0.1 mm (mm) of the plastic casing, the magnesium alloy casing Stronger and lighter. In addition, magnesium alloy also has good thermal conductivity and shielding of electromagnetic wave interference. Therefore, regardless of weight, thickness or use characteristics, magnesium alloy casings have gradually replaced traditional plastic casings.

However, the magnesium alloy sheet parts currently used in the stamping process are mainly AZ31 specifications, because the atomic structure of the magnesium alloy belongs to the hexagonal closest packed crystal structure (h.c.p.), and it is considered to lack formability. Therefore, the formability of magnesium alloys at room temperature is very poor, and they must be heated to above 200°C to have good formability. For example, when magnesium alloys are machined, press forming must be performed at a selected temperature (eg, 150° C. to 350° C.). Therefore, in the forming process of magnesium alloy materials, the operability, safety and manufacturing cost of the process must be considered.

In addition, it is also necessary to consider how to form the magnesium alloy material at room temperature, so as to quickly and stably combine multiple magnesium alloy plates together. For example, after each manufacturer adopts magnesium alloy to make the magnesium alloy case of notebook computers, and because the thickness and size of the case formulated by each manufacturer are different, it is necessary to combine two or two More than two magnesium-lithium alloy casings are combined with each other according to the size and thickness, so how to quickly combine two or more magnesium alloy casings at room temperature is an urgent problem to be solved in this industry.
