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.

A hydraulic tool includes a tool head and a moveable piston coupled to the tool head. The hydraulic tool head includes a plurality of jaws, which are operable to open and close for performing work on a workpiece. The hydraulic tool also includes a motor operable to drive the moveable piston to close the plurality of jaws to a closed position at which the work on the workpiece is completed. The hydraulic tool further includes a position sensor configured to detect when the plurality of jaws are at the closed position and responsively generate a sensor signal indicating that the plurality of jaws are at the closed position. Additionally, the hydraulic tool includes a controller configured to receive the sensor signal from the position sensor. The controller is configured to operate the motor based on the sensor signal that the controller receives from the position sensor.

A shearing apparatus includes a housing, a die within the housing, and a workpiece seat plate attached to the housing by a standoff. The die has a cutout which is positionable to align with a passageway through the housing. The workpiece seat plate is spaced from the housing by the standoff, and has a cutout which at least partially aligns with the passageway in the housing and the cutout in the die.

A table shear may include a clamp and a shearing mechanism, the shearing mechanism supported by the clamp. The shearing mechanism may include a fixed lower shear blade, a lower shear blade backup plate supporting the fixed lower shear blade, a moveable upper shear blade and a shear compression cylinder. The shear compression cylinder abuts the movable upper shear blade.

A tool head includes a first frame having a first arm and a second arm extending from a base to a distal end. The tool head may also include a first blade in the frame between the first arm and the second arm. The first blade is movable from the base toward the distal end. The tool head further includes a second frame hingedly coupled to the first arm. The second frame may include a second blade. The second frame is configured to rotate between a closed-frame position and an open-frame position. The tool head further includes a trip lever hingedly coupled to the first arm and configured to rotate between an open-lever position and a closed-lever position. The trip lever is in the open-lever position when the second frame is in the closed-frame position and the trip lever is in the closed-lever position when the second frame is in the open-frame position.

An assembly in accordance with some example embodiments includes a support structure, first and second plates coupled to the support structure, and a shearing apparatus operable to cut a workpiece between ends of the workpiece. The first plate engages and guides a first end of a workpiece, and the second plate engages and guides a second end of the workpiece. The shearing apparatus includes a stationary die and a movable die and coupled to the support structure between the first plate and the second plate.
