Stretch bending forming is widely applied to manufacturing high-pressure containers, boiler drums, boiler tubes, steel plates and ribs of ship bodies, various vessels, instrument and instrument components, cabinet inlaid strips and the like, and when materials are stretched, stress states of all parts in deformation areas are different. The portion in the middle of the cross section that is not deformed is called the neutral layer. The metal other than the neutral layer is under tensile stress to generate elongation deformation. The metal within the neutral layer is subjected to compressive stress to cause compressive deformation. Because the stress and strain directions of the metals at the two sides of the neutral layer are opposite, when the load is removed, the elastic deformation recovery directions of the metals at the two sides of the neutral layer are opposite, and different degrees of spring recovery are caused.
