Background
The metal pipe fitting is bent and formed by determining reasonable supporting points and stress points and applying certain bending moment or bending force. In the bending forming process of the pipe fitting, the outer side of the bending deformation area is subjected to tangential tensile stress, and the pipe wall is thinned and even cracked; the inner side is subjected to tangential compressive stress, the pipe wall is thickened, and even the pipe wall is unstably wrinkled; the resultant force of the two produces compressive stress inwards in radial direction, so that the cross section is flattened and distorted, and even collapses. After unloading, the rebound phenomenon is generated due to residual stress in the bent pipe and elastic deformation recovery. Therefore, the problems of stretch cracking, wrinkling, section distortion, rebound and the like easily occur in the pipe bending and forming process, and the pipe bending and forming process is a complex forming process with multiple forming defects.

After each metal pipe is bent and formed, the related forming performance index is measured.

Manual detection can also be adopted, but the measurement accuracy is low and the efficiency is low.
