摘要
介绍WD615型柴油机连杆螺栓孔挤压螺纹的工艺试验过程。通过试验证明,以挤压丝锥代替普通丝锥攻制螺纹,可提高螺栓孔的精度、螺纹强度,降低粗糙度。
This paper intreduces the development of an extrusion process of making the connecting rod bolt hole thread of WD615 Diesel engine. Test results prove that the threads formed by using the extruction taps instead of the commonly used taps are more accurate, with higher thread strengths and better surface finishes.
