ABSTRACT:
A pendulum-type flying shear having a speed range of a high speed to a low speed for shearing a hot rolled material having a large cross section in which there are provided vertically movable upper and lower cutting blades within a frame mounted on a crank shaft and the blades are moved towards and away from each other to shear the material while the frame is oscillated. Particularly, while the crank shaft is rotated at a constant speed, the oscillating speed of the frame is synchronized with the speed of movement of the material to be sheared and speed synchronizing apparatus including a gear device and the like is interposed between the oscillating device and the driving device so that a good shearing performance can be obtained with a small capacity of the driving device.
