摘要: 為了準確測量直角梯形鋼管幾何尺寸和預防拔制中截面扭曲,介紹了冷拔直角梯形鋼管底邊端點界定方法和截面形心等參數(shù)的計算。Abstract: The author introduces the definition of the end points on the bottom line of the cold-drawn right-angled trapezoidal steel tube and calculation of relevant parameters such as the cross-section center etc. thereof in order to get an accurate measurement of the said tube’s geometry and to prevent the tube from cross-sectional torsion during the course of drawing.
