利用上界法推导了冷拔内螺旋凸筋管拔制力计算式。实验表明,理论计算值与实测值较吻合,可为冷拔内螺旋凸筋管的拔制设备选型提供理论依据。
The upper bound method is used to derive the formula of drawing force of cold drawn internal spiral ribbed pipe. Experiments show that the calculated value is in good agreement with the measured value, which can provide a theoretical basis for the selection of drawing equipment of cold drawn internal spiral ribbed tubes.
