METHOD OF PRODUCTION OF A FILLER WITH A ZIGZAG CORRUGATED STRUCTURE Russian patent published in 2005 - IPC

FIELD: building industry; aircraft industry; transport mechanical engineering; methods of production of corrugated constructions with a folded structure.

SUBSTANCE: the invention is pertaining to the field of the methods of production of corrugated constructions with a folded structure used in the capacity of a filler of multilayered panels. The invention may be used in production of aircrafts, building industry and transport mechanical engineering. The invention provides, that the process of shaping a detail with a zigzag corrugated structure is preceded with a local slackening of a billet rigidity along the marking lines in the areas of a supposed bending by shaping of grooves along the zigzag lines of profile peaks determining a position of the peaks of the structure, and along the cuttings of the saw-type lines determining the peaks along these lines in the structure - on one side of the billet and along the zigzag lines of the pits of the structure - on the opposite side of the billet. On the all points of the lines intersection on the billet marking lines form pits. Slackening of rigidity of the billet may be conducted by a piercing of through holes of a small diameter along all the marking lines. After shaping of grooves and pits the billet may be given a slant relief according to the given zigzag corrugated structure. Then the shaping of the zigzag corrugated structure is realized by an additional pressure of the billet with the produced slant relief up to the structure with the given density of the relief. The method allows to receive with a high accuracy of a filler with the zigzag corrugated structure from the solid-sheet materials.

EFFECT: the invention ensures production with a high accuracy of a filler with the zigzag corrugated structure from the solid-sheet materials.
