摘要
研究内螺纹的振动挤压成形技术,通过实验分析了影响振动挤压攻丝扭矩的主要因素,基于实验结果揭示出各主要因素对攻丝扭矩的影响及其变化的基本规律。这些规律对减小扭矩、提高内螺纹质量和改善攻丝效果都有一定的理论和实践指导意义。
Researches the technique of vibration extrusion technology thread. The process of vibration extrusion tapping is simula- ted by using DEFORM-3D FEM software. Analyzed those factors to influence the torque of vibration extrusion tapping. Upon the results, the basis rules are analyzed. These rules are valuable to decrease the torque of vibration extrusion tapping, to improve the quality of tapping and promote the practise use of vibration extrusion tapping.
