摘要
进行了穿孔顶头不同径壁比对顶头工作锥纵裂的影响试验。分析了顶头工作锥纵裂的条件。试验表明,适当减小径壁比可抑制顶头工作锥纵裂,延长顶头使用寿命。
The paper involves an introduction to the experiments on the relationship between the plug working taper longitudinal crack development and the variation of the plug O.D.-W.T. ratio and an analysis of the conditions for the said crack development. Based on the experiments, a conclusion can be made that proper reduction of the said ratio will bring about a better supression of the crack, thus a longer service life of the plug.
