首先分析了环件轧制过程中环件的数学模型。通过对环件的受力分析,确定了形位辊抱辊力计算公式以及极值范围,对环轧机形位辊系统中各构件受力情况进行了分析,得出形位辊油缸的推力公式,对轧环机的设计以及控制方法提供了理论依据和参考标准。
The mathematic model of the ring in roiling process has been estahiished.Based on the force analysis of rolling ring, the calculation expression and limitation of guide force have been derived.The analysis of the force conditions of components in guide roller system has led the establishment of the force expression of guide cylinder hence theoretical reference and criteria for design and control strategy of rolling machine.
