Automatic adjustment mechanism for shear blade side gap

Abstract

The application discloses a kind of shear blade side gap automatic adjusting mechanism, including rack, the rack is provided with lower shear blade mounting seat, lower shear blade mounting seat is installed with lower shear blade, lower shear blade upper side is provided with upper shear blade, and upper shear blade is fixed in upper shear blade mounting seat, and upper shear blade mounting seat is fixed on upper crossbeam, further including upper shear blade crossbeam, the upper shear blade crossbeam is arranged between upper crossbeam and upper shear blade mounting seat, and the upper shear blade crossbeam is inclined wedge structure;The upper shear blade crossbeam of the application is inclined wedge structure, can drive ball screw to rotate by servo motor, thereby by bearing seat upper shear blade crossbeam is moved, thereby adjust the gap between upper shear blade and lower shear blade, and servo motor adjustment precision is high, and ball screw repeat positioning precision is high, by the setting of vertical locking structure and lateral pressure hydraulic cylinder, upper shear blade crossbeam can be locked, and it is stable and reliable.
