Abstract

Abstract:

Internal thread formation by cold extrusion based on low-frequency vibration can realize vibration extrusion by extruding tap. It can turn the process of dry friction into a more favorable state of boundary friction. Therefore it can overcome the defect of traditional cold extrusion that the coolant cannot easily enter the extrusion zone. The experimental study shows that: as the exciting frequency increases, so does the extrusion torque; as the exciting force increases, the extrusion torque decreases first, and then increases; as the exciting arm length increases, the extrusion torque also increases. Under the same conditions of the process parameters, the internal thread formation by cold extrusion based on low-frequency vibration exhibits a higher rate of thread teeth height and fewer defects of the teeth top than traditional methods, and the method can improve the fatigue strength and surface morphology of the thread so formed.

Key words: internal thread, cold extrusion, low-frequency vibration, extrusion torque, friction
