Abstract

The invention discloses a method for forming a foamed aluminum part with a complex curved surface. The foaming agent and stabilizer are evenly distributed between the metal plates, and the two stacked metal plates are welded for multiple times by friction stir welding to obtain a foamed aluminum prefabricated body; S3. Provide a heating mechanism or use a stamping die for heating The component heats and insulates the foamed aluminum prefabricated body in S2; S4, transfers the heated foamed aluminum prefabricated body to the stamping mold, closes the mold, stamps the foamed aluminum prefabricated body, opens the mold, and moves the punch to make a distance The concave mold is at a certain distance, and the heating component is started to heat the aluminum foam prefabricated body, so that it can complete the remaining foaming action, and the aluminum foam parts with complex curved surfaces can be obtained. The invention not only can mold any desired curved surface molded parts, but also has short duration and low cost of the whole process.

Description

technical field

[0001] The invention specifically relates to a forming method of a foamed aluminum part with a complex curved surface, which uses friction stir welding as a solid phase connection to prepare a foamed aluminum part with a complex curved surface. Background technique

[0002] As the lightweight development of automobiles is becoming more and more widespread, aluminum foam has gradually become one of the various lightweight materials with unique advantages. Aluminum foam has a unique pore structure that other lightweight materials do not have, and has many advantages such as low relative density, high specific strength, excellent mechanical response and good energy recovery ability, so it can be used in various parts of the vehicle that are vulnerable to impact. parts.

[0003] Simple aluminum foam sandwich panels cannot meet the requirements of daily automobile use, and various complex curved panels that meet the requirements must be obtained through forming t...
