Description

technical field [0001] The invention relates to a rapid detection device for spatially continuous bent pipes. Background technique [0002] Metal pipe fittings are bent into shape by determining a reasonable fulcrum and stress point and applying a certain bending moment or bending force. During the bending and forming process of pipe fittings, the outer side of the bending deformation zone is subjected to tangential tensile stress, and the pipe wall is thinned, or even cracked; the inner side is subjected to tangential compressive stress, and the pipe wall is thickened, or even wrinkled; The inward compressive stress causes the section to flatten and distort, or even collapse. After unloading, due to the residual stress inside the elbow and the recovery of elastic deformation, springback occurs. It can be seen that problems such as cracking, wrinkling, section distortion and springback are prone to occur during the bending forming process of pipe fittings, which is a compl...
