The subject of “development and application of automatic wire-drawing equipment for aerospace composite components” passed the acceptance test.
This topic is aimed at the urgent need of advanced manufacturing technology and equipment for large complex surface composite components in China’s aerospace industry. It has solved a number of technical problems and developed the first large-scale dynamic beam type gantry automatic wire laying machine in China.
On June 13, 2018, the Ministry of Industry and Information Technology organized an expert on the development and application of the “automatic wire-drawing equipment for aerospace composite components” led by Baoding Standard Aircraft Co., Ltd. in Shijiazhuang Aircraft Industry Co., Ltd. (Question No. 2014ZX04001- 091) A review and acceptance was conducted. The review experts agreed that the subject mastered the core technology of automatic wire laying equipment, filled the gap in the domestic industry, broke the blockade of the automatic wire laying technology of composite materials in developed countries, and agreed to pass the acceptance.
The leader of the acceptance expert group is Vice President Wang Jianguo of China Heavy Machinery Research Institute, Yang Yulin, Vice President of Yanshan University, Qu Bo, Party Secretary of Beijing Machine Tool Research Institute, and Zhong Zhongde, Vice President of China Academy of Mechanical Science, and domestic composite materials. Members of the expert group such as Xiao Jun, Wang Junfeng, Yao Feng, Qiu Haipeng and Gao Dawei, who are well-known experts in the field of automatic wire laying, participated in the review. Baoding Standard Machine Tool Co., Ltd., Shijiazhuang Aircraft Industry Co., Ltd., Xi’an Jiaotong University, Harbin Institute of Technology and Hebei University of Science and Technology and other research units have reported.
High-performance composite materials are widely used in aerospace, rail transit and wind power blades, new energy vehicles and other fields, and are urgently needed new materials in China. This topic is aimed at the urgent need of advanced manufacturing technology and equipment for large complex surface composite components in China’s aerospace industry. It has solved a number of technical problems and developed the first large-scale dynamic beam type gantry automatic wire laying machine in China. The equipment can accurately control the process parameters of the composite material placement, ensure the repeated execution of the automatic placement manufacturing process, ensure the stability of the composite component quality, improve the manufacturing precision and manufacturing efficiency of the composite component, and accelerate the domestic advanced composite. The pace of engineering application of automatic wire laying equipment.
At the equipment acceptance site, the automatic wire-laying equipment was used for automatic wire-laying of the overall tail-end segment fuselage skin test piece of the Kitty Hawk 500 aircraft. Sun Fengqin, deputy chief engineer of Shijiazhuang Aircraft Industry Co., Ltd. said that it would take more than 20 people to complete the work. After using automatic wire laying equipment, only two operators can complete the composite products with high quality and high precision. The manufacture greatly improves the production efficiency and product qualification rate, reduces the labor intensity, and reduces the consumption of raw materials and auxiliary materials.
At present, the results of the project have entered the stage of industrial application. Subsequently, Baoding Standard Machine Tool Co., Ltd. will provide high-performance domestic automatic wire laying equipment and technology with independent intellectual property rights for AVIC Composite Materials Co., Ltd., Beijing Satellite Factory Co., Ltd. and Hubei Sanjiang Aerospace Hongyang Electromechanical Co., Ltd. With the wide application of the research results of the subject in China’s aerospace industry, it will certainly lay a solid foundation for promoting the rapid development of China’s composite materials industry.
