<p>A pendulum shear for a continuous casting installation wherein the shear is provided with a mechanical drive for a pulse-like cutting operation, a knife or cutter rigidly connected with the pendulum and movable by a driven crank towards a second knife. Further, there is provided mechanism for accelerating the pendulum out of its rest position at approximately the maximum knife opening in the direction of travel of the strand, this mechanism, prior to the cutting operation, accelerating the pendulum at its cutting region to a speed approximately corresponding to the speed of travel of the strand. The mechanism for the acceleration of the pendulum consists of a guide arranged at the stand or housing and guides the pendulum along its path between the rest position and the start of the cutting operation, and the cooperation of this guide with the pendulum moved by the crank controls such acceleration.</p> |
