ABSTRACT:
The flying shear is designed as a crank rocker shear for crosscutting metal strips continuously fed thereto, with the crank effecting entrainment of strip cutting knives in the direction of strip movement and return of the knives in the opposite direction, and with the crank radius being adjustable in accordance with different cutting lengths of the strip. A cylindrical drum is rotatably mounted in the shear frame, and the crank axle is mounted within the drum to extend parallel to the axis thereof and for adjustment radially of the drum. Cooperating wedge surfaces are provided on the inner surface of the drum and on the crank axle, and the wedges on the crank axle are adjustable by a threaded spindle, having right hand and left hand threads, threaded through the wedges and rotatable, to adjust the crank radius, by a hydraulic motor. Hydraulically operated piston-cylinder actuators are effective between the inner surface of the drum and the crank axle to maintain the cooperating wedges firmly engaged with each other, and the radius adjusting mechanism rotates as a unit with the cylindrical drum which constitutes a crank shaft. A hydraulically operated mechanical clamp is effective to lock the threaded shaft against movement after adjustment of the crank radius.
