October 14, the reporter learned from Xi'an Yanliang National Aviation High-tech Industrial Base: the base enterprise Xi'an Xinghang Aviation Science and Technology Co., Ltd. (hereinafter referred to as 'Xinghang Aviation') independently developed the first domestic aircraft fasteners automatic sealing and gluing machine, the recent trial production success. Industry experts said that the successful trial production of the product will enhance China's civil aircraft manufacturing capacity, and promote the scale of production of domestic civil aircraft.
Industry experts, aircraft fasteners sealing and gluing is the aircraft assembly industry, especially large aircraft wing wall plate assembly in the indispensable key links. A C919 aircraft wing panels on the tens of thousands of fasteners need to be packaged glue sealing. Manual gluing faces high labour intensity, low efficiency, unstable quality, rework rate and other problems. In response to these problems, Xinghang aviation organisation R & D team, after three years of technical research and experimental verification, solved a large number of engineering and technical problems, and obtained the patent authorisation of the technology, and ultimately achieved the automatic sealing and gluing of aircraft fasteners. According to estimates, the successful application of automatic sealing and gluing technology can improve work efficiency by more than 50% and save more than 30% of glue materials, allowing domestic civil aircraft assembly to achieve high efficiency and low cost.
Xu Hong, general manager of Xinghang Aviation, told the reporter that the automatic sealing and gluing machine for aircraft fasteners has the functions of automatic positioning, automatic mould picking, automatic feeding and automatic gluing, etc. It can be widely used in the sealing and gluing of beams, frames, fuselage wall panels, wing wall panels and other fasteners of large transport aircraft, and it has won the unanimous praise of the users during the on-site test. The success of the trial production of the product highlights the strength of Shaanxi aviation manufacturing industry.
It is understood that the Xinghang aviation as a focus on large aircraft parts manufacturing technology enterprises, around the large aircraft parts manufacturing industry pain points, sustained high-intensity investment in research and development, and achieved a series of results. The company has solved the C919 aircraft spherical frame titanium alloy Y-shaped parts of the local substitution; overcome the C919 aircraft in the rear fuselage of the most complex four hyperbolic skin processing problems, to achieve the skin milling and cutting of low-cost, green and intelligent manufacturing, demonstrating the strength of Shaanxi's private enterprises in the field of aviation and bear.
