Breakthrough Of Forging Process For Key Parts Of Large Titanium Alloy And Aluminum Alloy In China

Breakthrough of forging process for key parts of large titanium alloy and aluminum alloy in China

Recently, as one of the important content of "high-end CNC machine tools and basic manufacturing equipment" of major national science and technology projects, undertaken by the heavy machine tool group, China's second "key large-scale forging technology research recently obtained the great progress.

Key issues surrounding the large aviation die forging forging near net shape forming technology, combining with construction of 800mn giant forging hydraulic press, the development of aviation complex precision forging of near net forming technology, to solve the large forging process of the general technology and key technical problems. Breaking the large titanium alloy, aluminum alloy forgings forming technology in aviation with typical titanium alloy, aluminum alloy, high strength steel based test data, forging forming process of meshless method simulation technology research, the typical structure of titanium alloy parts forming process lubrication protection technology research, forging process database / knowledge base research and development made remarkable achievements.

The research results of this project will be widely used in large, whole, fine, high quality, low cost, long life die forging products research and development, to provide the basis for the key parts of China's large aircraft manufacturing.

At present, the research for 800mn giant forging hydraulic press provides guidance for production process, to solve the large forging process based technology and key technical problems, near net shape forming technology has reached the international advanced level in our country. For the use of 800mn giant forging hydraulic press to create large, high-quality, large die forging lay good foundation.
