The world's largest heavy die forging hydraulic press project in Shaanxi, Xi'an, Yanliang, held a groundbreaking ceremony. Kang Kejun, vice president of Tsinghua University, a special trip to attend.

April 2, 2009, Tsinghua University and Shaanxi Province, the relevant units signed a 80000 tons of hydraulic machine major equipment project cooperation agreement. Such heavy die forging hydraulic press by Tsinghua University graduate design, mainly by prestressed bumpy ridge joining technology and steel wire winding prestressed structure, leading to the international level, China has independent intellectual property rights of major equipment items. After the project is completed, will be more than in the world has been forging equipment tonnage levels, to significant role in promoting, in gas turbine, ships, power plants, nuclear power, pressure vessels and other civilian large forging parts manufacturing on the broad application space for our country large-scale forging equipment and large scale plate parts, structural parts of the building, will also be large aircraft project, the development of national aviation industry of our country development lay the foundation. The project is located in Yanliang Xi'an aviation industry base, is expected to total investment of more than 1000000000 yuan, an area of 150 acres, will be implemented in three phases.

Hong Feng, vice governor of Shaanxi Province, Tsinghua University, Professor Yan Yongnian, Professor, as well as the Ministry of science and technology of Xi'an City, the relevant departments attended the groundbreaking ceremony. Jin Qin, director of the school science and technology development department, the Department of mechanical system director Ceng Pan, the party secretary of the country, also attended the ceremony. Ceremony held that dominated by the national Ministry of science and technology, Shaanxi Province, Xi'an, Yanliang aviation high-tech industrial base and Xi'an delta Aviation Technology Co., Ltd. aviation forging production base construction project officially started.

The project will in our country is in urgent need of aviation heavy die forging hydraulic press by Department of mechanical engineering, Tsinghua University proposed prestressed wire winding and cutting technology of bumpy ridge, set up to 8 million tons and 4 million tons of die forging hydraulic machine is core equipment of aviation forging production base. The project has been included in the national "five eleven" support program. Yanliang Xi'an region has focused on the development of a number of large aviation products, machine manufacturing and parts manufacturing enterprises, is China's only national aviation industry high technology base. 40000 tons, 80000 tons of heavy die forging hydraulic press, will meet the needs of large aviation die forgings, greatly enhancing the region and the country's aviation manufacturing capacity.

Since the 80s of last century, Department of mechanical engineering, Tsinghua University began to carry out the design and research of heavy die forging hydraulic press, the results "of 10MN prestressed steel wire winding multi cored forging hydraulic press" also won the second prize of Ministry of machinery industry science and technology progress. In recent years, research group led by Professor, Department of mechanical engineering, Yan Yongnian will prestressed wire winding technology further development, the prestressed section - bumpy ridge principle of structure design is proposed, to solve the problem of heavy parts processing, manufacturing, and transportation, laid an important technical foundation for the construction of heavy die forging hydraulic press
