METHOD OF STRENGTHENING FLAT PIECES Russian patent published in 1994 - IPC

Abstract SU 1459048 A1

FIELD: working materials. SUBSTANCE: thrown plate is used for straightening of surface 2 of piece 1 by explosion energy. The thrown plate is made of a material whose ultimate strength is less than one of piece 1 to be straightened. Thickness of the thrown plate shall be less than thickness of the piece. Value of hanging out of the trowed plate over surface 2 of piece 1 exceeds thickness of explosive charge that is used for strengthening. This allows to provide cutting out of band 7 in strengthening. Band 7 that is cut out over perimeter of surface 2 absorbs a part of energy of rarefaction waves. EFFECT: enhanced efficiency. 4 dwg
