不同挤压速度下冷挤压内螺纹振动信号研究
Research on Vibration Signals of Internal Thread Formed by Cold Extrusion under Different Extrusion Speeds
摘要
Abstract
The vibration signals of internal thread formed by cold extrusion under different extrusion speeds were researched.So the impacts of torque of internal thread formed by cold extrusion under different extrusion speeds can be explained by vibration signals.The results show that,as the extrusion speed increases,the frequencies of vibration signals move from low frequency to high frequency.The energy of vibration signals are mainly in the range of 625~1250Hz,and the more energy of this freguency range have,the more extrusion torque decrease.关键词
