Compression molding method for spatial distortion curved plate

The invention discloses a compression molding method for a spatial distorted curved plate. The technical problem that in the prior art, the whole spatial distorted curved plate with the large area cannot be subjected to compression molding at a time is solved. The curved surface of the spatial distortion curved plate is decomposed into a plurality of lines with different curvatures, the lines with the same slope on the spatial distortion curved plate serve as bending lines, the bending angles of the inner arc bending lines and the outer arc bending lines are drawn, and bending equipment with an upper die as a straight line is adopted for pressing the bending lines one by one, so that the planar raw material plate is distorted into the spatial distortion curved plate. The device is scientific and reasonable in design, can press and form the spatial distortion curved plate at one time, and is high in pressing speed, high in efficiency and accurate in curved surface degree control, so that the quality requiremen
