A certain type of standard titanium alloy high-locking bolt developed by China Aerospace 694 Factory passed the process review of the assessment team composed of aerospace and aviation system experts. This marks the successful completion of the development task of the titanium alloy high-lock bolts, which lasted more than three years, and made a major breakthrough in the localization of titanium alloy high-lock bolts.
The high-locking screw connection pair composed of high-lock bolt and high-lock nut has the characteristics of light weight, small volume, strong anti-loose ability, good anti-fatigue performance and high assembly efficiency, and can realize single-side tightening operation of maneuvering in aerospace. The field has a wide range of uses. Due to the complex structure, mechanical properties and strict requirements, the development of titanium alloy high-lock bolts is very difficult. In order to break the foreign technology monopoly and blockade of the high-lock fastener manufacturing industry and improve the technological level of China's standard parts manufacturing industry, in early 2004, the 694 plant began the trial production of titanium alloy high-lock fasteners.
In the past three years, scientific and technical personnel have made unremitting efforts to solve a series of technical problems, and have broken through a number of technical barriers. They have completed the development tasks of the first batch of titanium alloy high-lock bolts. After the appraisal and inspection, all performance indicators meet the requirements. The successful development of this topic has filled the gap in the domestic high-lock fastener manufacturing industry, breaking the monopoly of foreign high-lock fastener manufacturing, and laid a solid foundation for the realization of the high-lock fasteners.
