通过分析滚压钛合金紧固件饱满螺纹所产生的种种弊端,如容易产生滚压裂纹而降低紧固件的疲劳寿命、降低滚丝轮的使用寿命、造成检测麻烦、产生安装损伤等,在参照国外大径修正螺纹的基础上,提出了对钛合金紧固件螺纹大径进行修正的设想,进行了修正螺纹大径尺寸设计,制造了试验件并进行了试验。滚压螺纹试验及螺纹的机械性能试验表明,修正螺纹大径是可行的,可带来诸多好处。
By analyzing the disadvantages of full thread of rolling titanium alloy fasteners, such as easy to produce rolling cracks and reduce the fatigue life of fasteners, reduce the service life of the rolling wheel, resulting in the detection of trouble, resulting in installation damage, etc., in the On the basis of referring to the foreign large diameter correction thread, the idea of amending the large diameter thread of the titanium alloy fastener was put forward. The diameter modification of the thread was designed, the test piece was manufactured and the test was carried out. The rolling thread test and the mechanical test of the thread show that it is feasible to correct the large diameter thread, which can bring many benefits.
