Analysis of Equal Tension Pre-Tightening of Steel Wire Winding Split Ultra-High Pressure Die

  • 摘要: 针对超高压装置大型化受限于大质量硬质合金加工困难等问题,设计了一种新型的钢丝缠绕剖分式两面顶超高压模具。该模具主要由内部的剖分式压缸和外部的预应力钢丝组成。对采用等张力钢丝缠绕模具进行了力学模型分析,并通过有限元软件对剖分式压缸和钢丝缠绕层进行研究。结果表明:加载后压缸腔体的最大等效应力出现在压缸腔体内壁;压缸腔体尺寸稳定性与钢丝缠绕层数及钢丝直径成正比;在缠绕层内部,钢丝轴向应力与钢丝直径成反比,与缠绕层数成正比。
