Abstract

The invention relates to an integrated forming device and method for aluminum matrix composite thin-walled pieces. The device comprises a preparing-pouring tank (1) and a pressurization tank (6), wherein the preparing-pouring tank (1) and the pressurization tank (6) are used for preparing aluminum matrix composites. The preparing-pouring tank can be vacuumized through a vacuumizing device. The pressurization tank can be pressurized through a pressurization device. A gypsum mold can enter the preparing-pouring tank from the pressurization tank through a conveying window to conduct pouring. The stable-quality and integrally-formed aluminum matrix composite complex thin-walled pieces are obtained through the method of preparing and pouring the aluminum matrix composites under the vacuum condition and conducting solidification at high pressure. The interiors of the obtained castings are free of defects such as slag inclusion, shrinkage porosity and pores, and the castings are compact in structure, good in performance and capable of meeting production requirements. The device is easy to popularize, suitable for producing the aluminum alloy composite complex thin-walled pieces on a small scale and high in casting yield.

Description

technical field

[0001] The invention belongs to the field of forming and casting of composite materials, and in particular relates to an integrated forming device and method for thin-walled parts of aluminum-based composite materials. Background technique

[0002] The development of modern science and technology has put forward higher requirements on the performance of materials. It is expected that they will have good comprehensive performance and they will be able to serve under extreme environmental conditions such as high temperature, high pressure, high vacuum and radiation. Particle-reinforced aluminum matrix composites not only have the advantages of high toughness and high plasticity of metals, but also have the advantages of high hardness, high modulus, and high thermal stability of reinforcement particles. Widespread attention. American scholar Logsdon once proposed that the future development prospects of aluminum matrix composites mainly lie in non-long fiber re...
