多工位冷镦螺帽穿孔冲头的主要失效形式为刃部磨损。选用适当的材料并经铬钒共渗表面强化处理可以显著提高冲头的使用寿命。铬钒共渗法的研究近年才开始。本文略述了共渗方法。
Multi-station cold heading nut perforation punch the main failure of the form of blade wear. Choosing the right material and chrome vanadate surface strengthening treatment can significantly improve the service life of the punch. Research on chromium vanadium co-infiltration has only begun in recent years. This article outlines percolation methods.
