Abstract

PURPOSE: To obtain the shearing force strong enough to cut a thick and long high- temperature steel piece such as continuous casting slab into a fixed size by adopting a screw system instead of a hydraulic system and thereby simplifying the structure in a down-and-up cut method.
CONSTITUTION: A pneumatic balance cylinder 15 is arranged in the front and rear on an upper frame 2, while the tip of a piston rod extending from the piston of the cylinder downward into a machine frame is fitted pivotally to the connection bar 17 of a C-shaped frame 16. And thus the weight of an upper blade slide 6 is supported in balance by the pneumatic force introduced in the cylinder 15. In the frame 2 a pressure screw 20 is arranged and screwed thereto. Moreover, a screw-system pressure device can give nonstaged fine adjustment to the required aperture between the slab S and an upper shearing blade 5 by lowering the slide 6 through the rotation of the screw 20, and also can support the entire shearing force acting on the slide 6 in up-cut shearing.
