为加速我国旅游车制造工艺技术的进步,沈阳飞机制造公司使用结构合理的铸造模具及粘附度适宜的铸造涂料,制造出4种不同规格的球头节。这些铸造式球头节表面光滑,结构精巧,球头与壳体动配合间隙均匀,球头摆动灵活,经高温、低温、静力测试以及6万次加载摆动疲劳试验和装车使用证明,已达到国外同类产品的先进水平。这项制造技术填补了我国铸造工艺技术的一项空白,同时拓宽了我国铸造技术的加工领域。 In order to speed up the progress of China’s manufacturing technology of coaches, Shenyang Aircraft Manufacturing Co., Ltd. used 4 types of ball joints with reasonable structure and casting paint with proper adhesion. These casting ball head section smooth, compact structure, the ball head and the shell with a uniform movement of the ball swing swing flexible, high temperature, low temperature, static test and 60,000 load swing fatigue test and loading proved to have To reach the advanced level of similar foreign products. This manufacturing technology has filled a blank of China’s foundry technology and at the same time broadened the processing field of China’s foundry technology.
