Embodiment 1

[0038] The target product of this embodiment is the connector of the magnesium alloy Gleeble thermal simulation sample. First, purchase the AZ31 magnesium alloy ingot, and use wire cutting to cut the original material into 2 cylinders of Φ10mm * 7.5mm (such as figure 2 5 and 6), and sanded and polished, then spliced ​​and preheated, then compressed and insulated. Specific steps are as follows:

[0039] The first step is to cut the original material according to the predetermined size, take the AZ31 magnesium alloy material with a thickness of 30mm, cut a Φ10mm cylinder with wire cutting, and then use a lathe to cut the cylinder to a height of 7.5mm, because the thermal simulation press used cannot The direction of travel of the cylinder is fixed, so it is necessary to ensure that the two sections of the lathe machined cylinder are parallel;

[0040] The second step is to grind the cylindrical surface of the cylinder (that is, the splicing surface, in the figure 2 8 and 9) ...

Abstract

The invention provides a magnesium alloy component warm heating forming method based on diffusion bonding, and belongs to the technical field of stamp forging forming. A magnesium alloy component is formed sequentially through preheating, compressing and heat preservation treatment after composition components are spliced. The preheating temperature is 350-400 DEG C, and the compressing temperature is consistent to the preheating temperature. The forming method can solve the problem that forming of magnesium alloy components with local small characters, special shapes and uneven wall thicknesses is difficult; and meanwhile, through the forming method, the production cost can be reduced, and the product quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of punching and forging, in particular to a diffusion bonding-based warm forming method for magnesium alloy parts. Background technique [0002] Metal magnesium and its alloys are the lightest structural metal materials used in engineering so far. Magnesium alloys characterized by light weight, good rigidity, good metallic luster, good electromagnetic shielding and easy recycling have become modern automobiles, electronics, The preferred material for communication and other industries. At present, magnesium alloy products are obtained by casting, and its disadvantages are low yield, more holes and looseness, low strength, poor ductility, and cannot meet the higher requirements of the product. The thickness should not be too thin, which cannot meet the light, thin and short requirements of magnesium alloy electronic products. [0003] Sheet metal stamping and forming processing methods have significant adva...
