METHOD OF MANUFACTURE OF A RELIEF DETAIL WITH A ZIGZAG-SHAPED CHANNELED STRUCTURE (VERSIONS) Russian patent published in 2005 - IPC

FIELD: methods of manufacture of the channeled constructions with a buckle structure made out of sheet materials.

SUBSTANCE: the invention is pertaining to the methods of manufacture of the channeled constructions with a buckle structure made out of sheet materials. The method includes delivery of a blank in the area of the form-shaping and bending of a sheet blank on zigzag and saw-tooth lines according to the form of the cells of the zigzag structure. Manufacture of a relief detail is conducted a step-by-step in a cyclic mode, using which in the area of the form-shaping mold the combined buckle structure consisting of a zigzag corrugations and a triangular corrugations. Ribs of a triangular corrugation are oriented in a direction of delivery of a blank. A zigzag corrugation is conjugated with a triangular corrugation along the saw-tooth or zigzag lines oriented across a direction of the blank delivery. According to the first version during one cycle a relief detail is shaped, then the zigzag and triangular corrugations of the combined buckle structure are cyclically stretched up to a planar state and the blank is drawn into the area of the form-shaping by the given value for formation of a required length of the relief detail with the zigzag channeled structure. According to the second version to the form-shaping of the combined buckle structure may precede a local weakening of rigidity of the material along the zigzag line of the blank saliences and concaves from the different sides of the blank. The given engineering solution expands technological capabilities of manufacture of relief details.

EFFECT: the invention ensures expansion of the technological capabilities of the relief details manufacture.
