冷弯成型变形复杂，实验研究是冷弯成型研究中不可缺少的一部分。采用电阻应变片测量法和网格法对冷弯成型过程进行研究，并以直缝焊管为例，对带材的变形及弹复等进行综合测试，获得了许多有价值的实验数据，有助于工厂改进工艺，生产出高质量的产品。
Cold bending forming complex, experimental research is an indispensable part of cold forming research. The research of cold forming process is carried out by the method of resistance strain gage measurement and the grid method. Taking the straight seam welded pipe as an example, a comprehensive test is conducted on the deformation and the rebound of the strip, and many valuable experimental data are obtained, Improve the process in the factory, to produce high-quality products.
