Abstract

The invention relates to an integrated preparing and forming device for magnesium alloy thin-walled pieces. The forming device comprises a smelting-pouring tank and a protective atmosphere solidification tank, wherein the smelting-pouring tank and the protective atmosphere solidification tank are used for preparing a magnesium alloy. The smelting-pouring tank and the protective atmosphere solidification tank are both connected with a vacuumizing device and a protective gas injection device. By means of the integrated preparing and forming device, the magnesium alloy can be smelted under the vacuum condition, preparation is completed and pouring is conducted under the condition that the protective gas is injected, and pressurized solidification is conducted under the condition that the protective gas is injected in the protective atmosphere solidification tank. The integrated preparing and forming device is suitable for producing complex and thin-walled magnesium alloy castings, the production safety is high, the surfaces of the castings are free of oxidation defects, internal defects such as slag inclusion, shrinkage porosity and cold shut are basically solved, the structure is compact, performance is good, production requirements are met, the integrated preparing and forming device is easy to popularize, and the yield of the castings is high.

Description

technical field [0001] The invention relates to the field of alloy material preparation and forming casting, in particular to an integrated preparation and forming equipment for magnesium alloy thin-walled parts. Background technique [0002] Magnesium alloy has light specific gravity (similar to plastic), high specific strength, specific stiffness close to that of aluminum alloy, damping, thermal conductivity, machinability, good casting performance, strong electromagnetic shielding ability, stable size, rich resources, and easy recycling. And a series of advantages, it has a wide application space in the fields of automobile industry, communication electronics and aerospace. In recent years, with the lightweight of the automobile industry, the demand for environmental protection and the continuous progress of magnesium alloy research and development technology and recycling technology, the rapid development of magnesium alloy has been promoted. Due to the high activity of...
