Description

A reference positioning mechanism for rapid detection of elbows

technical field

The utility model relates to a reference positioning mechanism for rapid detection of bent pipes.

Background technique

Metal pipe fittings are bent and formed by determining a reasonable fulcrum and force point and applying a certain bending moment or bending force. During the bending and forming process of the pipe fitting, 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, the pipe wall is thickened, or even wrinkled; The inward compressive stress causes the section to be flattened and distorted, or even collapsed. After unloading, due to the residual stress inside the elbow and the recovery of elastic deformation, a rebound phenomenon occurs.
