本文给出了计算钢管穿孔机轧制压力、导板力、轴向力、平均单位压力和金属与轧辊间接触面积的简单公式,这些公式是根据大量实际测定数据得出的。文中还讨论了计算轧制力矩的理论公式。用这种方法来计算穿孔机力能参数对于工程计算是很方便的,而且有足够的计算精确度。
In this paper, a simple formula for calculating the rolling pressure, the guide force, the axial force, the average unit pressure and the contact area between the metal and the roll of the steel pipe piercer is given. These formulas are based on a large number of actual measured data. The paper also discusses the theoretical formula for calculating the rolling torque. Using this method to calculate piercing machine energy parameters is very convenient for engineering calculation, and there is enough calculation precision.
