Metal plate double-curved surface processing technology and equipment

The invention discloses a metal plate double-curved-surface processing technology and metal plate double-curved-surface processing equipment. The technology comprises the following steps of rolling a metal plate to be processed by using a triaxial roll bending machine, and adjusting the distance among three rollers to obtain different unidirectional curvatures, wherein convex and concave shaft sleeves are sleeved on three rollers of the roll bending machine; and allowing the metal plate to be processed to pass through the roll bending machine sleeved with convex and concave shaft sleeves to obtain a double-curved-surface plate which has a required shape. In the technology, the shaft sleeves are coated by a strip, the axial curvatures of the shaft sleeves are adjusted, and the resilience capacity of the metal plate is adjusted in a matched way. The double-curved-surface roll bending machine is provided with three rollers and is sleeved with the convex and concave shaft sleeves of which the curvatures are match
