Abstract
An extrusion press shearing device includes: a converter that converts rotational motion of a ball screw into linear motion of a shearing slide drive frame; a shearing slide attached to the leading end of the shearing slide drive frame; and hydraulic cylinders attached to the shearing slide drive frame, wherein the ball screw of the converter and the hydraulic cylinders are arranged in parallel, and the ball screw is rotated to move the shearing slide vertically so that a discard is cut off by the hydraulic cylinders.
