FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used in fabricating modular metal panels consisting of sheets and ribs or sections, moulded or welded panels. First, lengthwise forces are applied along stiffness rubs to curve the panel along said ribs. Then, crosswise forces are applied, along with heating, to wedge-like panel sections located across stiffness ribs. Note here that wedge base width and spacing between said sections are selected in proportion to preset radii of curvature, while billet is heated through its height.
EFFECT: reduced labor input, higher efficiency.
