高性能航空紧固件都要求在热处理后进行螺纹滚压，以保证螺纹具有对疲劳寿命有利的压应力状态。高强紧固件螺纹在冷滚压成形过程中易产生裂纹、折迭等缺陷。此外，工具寿命较低。主要论述了高强紧固件螺纹成形的技术难点，提出了采用温滚压成形工艺技术方法。通过温滚压温度参数试验、试验件的金相和性能试验，并与冷滚件进行了对比，温滚压成形在提高工件质量和滚压工具寿命方面具有无比的优越性。

The thread of high strength aero-space fasteners should be rolled after the heat treatment,this process keeps the thread having the press stress state ben-eifting to fatigue life.The high strength fasteners with cold rolling are easy to produce defects such as cracks and en-folds.In addition ,toll’s life is low. The thread forming dif-ifculties of the high strength fasteners are discussed, warm rolling technology method is put forward. Through warm rolling temperature parameters , metallurgical testing of test pieces and performance tests, and compared with cold rolling pieces, warm rolling in improving the quality of pieces and life of the toll has incomparable superiority.
