Shear system of extrusion press

Abstract

A shearing device for an extrusion press is adapted for cutting off from each other an extruded product and a discard which is the residue of a billet, the shearing device being configured so that the configuration thereof is simplified to reduce costs required for maintenance and production and so that the gap between the shear blade and an end surface of a die is automatically adjusted to improve the shearing accuracy, thereby providing a satisfactory cut surface. A shear cylinder (21) is mounted in a downward facing position to a frame (16) provided on the side of an end platen (11) which faces a container (10). A shear guide (18) is mounted to the frame (16) in a tiltable manner, the shear guide (18) having a shear blade (24) which is provided at the lower end thereof and guiding a shear slide (23). A tilt cylinder (19) for the shear guide (18) is mounted to the frame (16), the tilt cylinder (19) being capable of keeping the gap between the front face of a die stack (12) and the shear blade (24) constant by pressing the shear guide (18) against a horseshoe (26). The piston rod (22) of the shear cylinder (21) is mounted to the shear slide (23) so as to be capable of tilting and sliding.
