FIELD: process engineering.
SUBSTANCE: invention relates to machine building and may be used for cutting sheet metal. Proposed device comprises first top knife cutting blade and second bottom knife cutting blade, drive with, at least, two revolving camshafts coupled via couplings with, at least, first cutting blade. At least, one coupling element allows adjustment of its length. Each coupling element incorporates mounting element to adjust its length made up of cylinder-piston unit made up of cylinder and piston. Sais element allows controlling sheet material cutting.
EFFECT: variable geometry of cutting different-thickness sheets.
