摘要
本文从拉梅公式,莫尔强度理论出发,通过引入拉压强度极限比V、等强度系数β,导出了单镶套模具的设计公式;揭示了容许内压p随K、β、V、[σ]的变化规律;提出了予紧过盈量的最佳选择范围。通过算例说明合理选择配对材料和适当加火过盈量是提高模具寿命的有效途径。
In this paper, according to leme equations and mohr's theory, the new design formulas of single shrinking-on cold forming die arc deduced from introducing tension-compression specific intensity factor V and equal intensity factor β. it is important to show the allowance inner pressurc p as functions ofK. V. β.[σ] and put forward the best range of shrinking-on allowance. Reasonable selecting die material and increasing shrinking allowance arc interpreted as the effective measures for lasting die life.
