Guangdong Maino Industrial Technology Co., Ltd., in collaboration with China Heavy Machinery Research Institute, Jilin University and other scientific research units, successfully developed the world's largest 1,230-ton skin stretching machine over three years, and recently passed the acceptance inspection.This equipment fills the domestic gap in this field, overcomes the "stuck neck" problem of long-term dependence on imports of key equipment in the aviation manufacturing field, and achieves effective transformation from the laboratory to the production line through digital technology, injecting strong impetus into the localization process of my country's aviation manufacturing, high-speed rail, high-precision construction and other industries.
This equipment introduces aerospace technology into the construction field for the first time, using digital modeling to achieve "one-click molding".The science and technology museum curved component project that used to take a year and a half can now be completed in just two months, with the construction period reduced by more than 70% and the cost reduced by 35%.
More importantly, its molding accuracy reaches 0.1 mm level, far exceeding the level of traditional equipment, marking that my country has achieved a leap from "following" to "leading" in the field of aircraft skin molding.
For a long time, China's aviation manufacturing industry has relied on imports for about 60% of its core components, especially key links such as aero engines and flight control systems.The successful acceptance of the 1,230-ton skin stretching machine is regarded as an important breakthrough in completing the "last piece of the puzzle" in aviation manufacturing, making China the first country in the world to master "dual-mold molding" technology.
Zhang Kangwu, deputy chief engineer of China Heavy Machinery Research Institute Co., Ltd., said: "The successful research and development of this project can be widely used in the aviation industry in the future. It will play an important role in the maintenance and support of C919 large aircraft, subsequent 929, Y-20, seaplanes and various types of fighter jets. It has effectively solved the country's 'stuck neck' problem in key manufacturing equipment, and is of great strategic significance."
Liu Chunguo, a professor at Jilin University, pointed out: "The currently successfully developed 1,230-ton skin stretching machine is the largest in the world. In addition, the supporting multi-point skin stretching equipment has also achieved digital control. Both sets of equipment have reached the world's leading level, fundamentally solving my country's technical bottleneck in aviation skin molding, making my country not only an international leader in this type of equipment, but also at the forefront globally."
