Heavy-duty forging hydraulic press is a strategic and basic equipment related to national security and economic development. Today's aviation powerhouses in the world have more than 45,000 tons of heavy-duty forging hydraulic presses. For example, the United States has two 45,000-ton heavy-duty forging hydraulic presses. Russia has two 75,000-ton heavy-duty forging hydraulic presses. France has a 65,000-ton heavy-duty forging hydraulic press. Today, in Beijing, through the expert committee to demonstrate the construction plan of the 80,000-ton die forging hydraulic machine major equipment project, the project will be officially launched in May this year.
It is understood that the 80,000-ton heavy-duty forging hydraulic press was designed and designed by Tsinghua University. The project creatively uses modern prestressing technology and wire-wound prestressed structure, which is a major equipment project with independent intellectual property rights in China. Yan Yongnian, a professor at Tsinghua University, said in response to a question from the reporter that before China had only 30,000 tons of die forging hydraulic presses, China had to develop its own heavy-duty forging hydraulic press to realize the independent development of large aircraft. After the completion of the 80,000-ton heavy-duty forging hydraulic press project, it will be the world's largest tonnage hydraulic press with the largest tonnage and the strongest pressing capacity. He emphasized that the prestressed wire winding technology and the prestressing technology are used in the heavy forging hydraulic press, which is the first in the world; the first time in the world, the technology of the frame is not moving and the heavy parts are wound by the robot.
According to Jin Gansheng, director of Xi'an Yanliang National Aviation Industry Base Management Committee, the project includes both Shaanxi Industrial Investment Company, Xi'an Yanliang National Aviation Industry Base, and state-owned enterprise China Airlines Hongyuan Aviation Forging Co., Ltd. The company Xi'an Triangle Aviation Technology Company and Tsinghua University participated in the system and the mechanism is flexible and advanced. The total investment of the project is 1 billion yuan. The 40,000-ton die forging hydraulic press of the first-stage project of 80,000 tons of die forging hydraulic press will be completed and put into production at the end of 2008; the 80,000-ton die forging hydraulic press of the second phase will be completed by the end of 2010. After the project is completed, it will surpass the tonnage level of forging equipment in Russia, the United States, France, Germany and other countries, laying a solid foundation for the take-off of large aircraft in China.
