摘要
推导了外螺纹铜管拉伸延伸系数计算公式。通过理论计算与实验结果的比较,表明该公式有很高的计算精度,完全可以满足工艺计算要求。
The coefficient of elongation is an important parameter for drawing up technology before production . So this paper deduces the calculation formula for it of outer-spiral-fin copper tubes . The comparision between the theoretical calculation and the experimental result proves that the formula has high precision in calculation and is able to meet perfectly the demands of technological calculation .
