Abstract A device is provided for the high speed severing into lengths of an elongated material product issuing continuously at high speeds from refined steel mills or wire mills. The product may be rolled wire, for example, moving continuously from the mill through rotating guides. The invention incorporates cooperating radially movable shears directly into two cooperating rotating guides for the wire. The shears are connected to reversible pressure fluid piston and cylinder arrangements also incorporated into the cooperating rotating guides. Actuation of the shears from retracted to cutting positions and vice versa is through pressure fluid lines positioned in the axis of the rotating guides and connected to controls for coordinating the speed of the material to be cut and the speed of the rotating guides with the movement of the shears.
A shearing device for cutting rolled material, such as wire moving at high linear speeds into lengths comprising a pair of cooperating rotating guides for guiding said rolled material linearly, and a radially displaceable cutting blade in each said guide for cooperating movement into and out of the path of said rolled material, characterized by a. an hydraulic reversible fluid pressure piston and cylinder unit disposed in each said rotating guide and rotatable therewith; b. the piston of each said unit connected directly to said radially movable cutting blade in its respective rotating guide; c. servo-control means connected to each said piston and cylinder units for the cooperative actuation thereof to cut said rolled material into lengths; and d. said servo-control means for each said reversible piston and cylinder unit is mounted on said rotating guides adjacent their respective reversible unit.
