薄壁弱刚性钛合金结构件制造工艺

随着新型材料冶金技术的发展与进步,钛合金作为“崛起的第三代金属”已完全替代了铝镁合金和钢构件,成为航天飞行器上应用范围最广的材料之一。从某新研制航天飞行器外部结构件用钛合金材料的特性及切削特点入手,针对薄壁弱刚性钛合金结构件在实际加工过程中遇到的诸多难点,提出了相应的解决办法,并重新设计了零件工装。结果表明,改进措施不仅保证了零件质量,而且提高了零件加工效率,使单件零件的生产周期缩短了近10h。

Machining Technology of Weakly Rigid Thin-walled Titanium Structral Member

With the progress of new material metallurgy technology,titanium alloy as the third-generation rising metal has completely replaced the aluminum magnesium alloy and steel members,and become one of the most widely used alloys in aerospace.The characteristics of titanium alloys used by one aircraft are studied,the corresponding solutions are put forward,the new product tooling is designed.The practical applications show that,the measures can ensure product quality and enhance production efficiency,and the single part production cycle time is reduced by about 10 hours.
