SYNCHRONICALLY MOVING HYDRAULIC SHEARS WITHOUT STAND Russian patent published in 2017 - IPC B23D15/06 B23D25/04 

FIELD: machine engineering.

SUBSTANCE: shears (1), in particular, cross cutting shears for cutting flat material, include a holder (2) of the upper blade and a holder (3) of the lower blade. And at the holder (2) of the upper blade and/or the holder (3) of the lower blade is guided to move up and down and adapted to move by means of at least one device (4, 5) relative to the other blade holder (3, 2).
