SHEARS KNIFE CLAMPING FIXTURE FOR CROSSWISE BAND SEPARATION Russian patent published in 2009 - IPC B26D7/26 

FIELD: mechanics.

SUBSTANCE: fixture includes a piston with pressure surface and piston rod, bevel-face clamp bar, which presses cutter against retaining bars and is connected to the piston rod, fastening device for the clamp bar, compression spring to move the clamp bar off the cutter with subsequent cutter release, and cover. The fixture is equipped with the second piston with the second pressure surface, which is located at a distance from the first piston, and the piston rod area is obtained between them. Both obtained pressure surfaced of the pistons are designed to compress the above compression spring, when they are loaded with process medium. This allows for knife movement within a longitudinal pick-up unit or complete knife removal for replacement or grinding.

EFFECT: increased knife release force and shears cutting effort.
