SUPPORTING DEVICE FOR SHEET MATERIAL CUTTING SHEARS Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: supporting device for shears has load-bearing bar, supporting member kinematically linked with power drive unit, and control system. Load-bearing bar is installed in zone of shears rear stops. Supporting member is made in the form of rigid frame having strips located between rear stops of shears and having downward bent L-shaped front edge. Supporting member is located on load-bearing rod for possible turning in vertical plane at reciprocal motion towards cutting member of shears between position of contacting L-shaped front edge of rigid frame with rear stops of shears at which space between cutting member of shears and rear stops of shears is free, and position at which L-shaped front edge of rigid frame is located in zone of cutting edge of shears lower blade and part of space between shears cutting member and rear stops of shears is limited, with possible fixing in preset position. Power drive unit is located on load-bearing bar at side which is opposite to cutting member of shears. EFFECT: high efficiency. 2 cl, 3 dwg
