全面深入地分析了冲床压塌块传统设计理论存在的问题，应用疲劳断裂理论和机械可靠性设计基本理论，深入分析了压塌块剪切破坏工作过程、失效机理及其剪切强度应具备的特性；明确指出压塌块保险系数的选择方法；建立了完整的压塌块机械可靠性设计理论，分析和明确指出提高压塌块工作可靠性和使用寿命的方法。
The problems existing in the traditional design theory of press collapse block are analyzed comprehensively and deeply. By applying the theory of fatigue fracture and the basic theory of mechanical reliability design, the working process, failure mechanism and shear strength of collapse are analyzed in depth The method of choosing the insurance coefficient of collapsing block is clearly pointed out and a complete design theory of mechanical reliability of collapsed block is established. The methods to improve the working reliability and service life of collapsed block are analyzed and specified.
