The hot test of 300MN die forging hydraulic press developed by our institute was successful.
On the morning of June 9, 2023, the 300MN die forging hydraulic press was successfully tested in Beijing Iron and Steel Research Gaona Technology Co., Ltd. (Deyang forging base site), marking my country's progress towards the realization of large-scale die forging in the aviation and aviation fields. An important and solid step has been taken in the development and production.
300MN die forging hydraulic press
The 300MN die forging hydraulic press was developed by Tianjin High-end Equipment Research Institute of Tsinghua University. It is another heavy precision forging hydraulic press project after the 400MN aviation die forging hydraulic press and 300MN isothermal forging hydraulic press projects. The equipment has completely independent intellectual property rights and adopts the "wire prestressed winding split-kanghe" technology independently developed by Tsinghua University to solve the difficulties in the design of extra-large bearing frame and the design and manufacturing technology of ultra-high-high pressure and super-large tonnage servo master cylinder, it has the characteristics of high stiffness, high fatigue and high precision. The equipment adopts a single master cylinder 8 balance cylinder layout and a single load-bearing frame structure layout, which is one of the best layout structures for forging and forming aviation precision die forgings. Equipment control accuracy, forging accuracy and other indicators have reached the world-class level.
