摘　　要：高速加工和新型材料的发展,对传统丝锥工具提出了更高的要求,硬质合金丝锥产品也得到了更多的重视。但硬质合金的脆性大,承受扭力的特性差,因此需要对螺纹的截形及结构的设计和制造进行研究。本研究从实际工程应用出发,提出一种精微整体硬质合金挤压丝锥工具,介绍了其设计与分析过程,并结合应用案例进行验证。High speed machining and new material has raised higher requirements on tap tools,including more recognized hard alloy taps.However,the hard alloy is brittle and sensitive to torsion,requiring further focus on the design and manufacturing of the profile and the structure of the thread in the tap.In this study,a mico-precision solid hard alloy extrusion tap is proposed based on engineering applications.The design and analysis process is introduced.The tap is validated through practical cases.
