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.

A power tool includes an outer housing having a drive unit support portion and a handle portion, an inner housing positioned at least partially within the handle, and a drive unit positioned in the drive unit support portion. The drive unit includes an output shaft extending at least partially through the handle portion. The power tool also includes a ball screw mechanism having a nut supported at least partially within the inner housing and a screw coupled to the nut for relative axial displacement therewith in response to relative rotation between the screw and the nut. Torque from the output shaft is applied to one of the nut and the screw to cause the relative rotation. The handle portion exerts a reaction torque on the inner housing in response to the relative rotation between the nut and screw to prevent the inner housing from rotating relative to the outer housing.

Hydraulic two-side rolling-cut shears, including: a front transport roller device, a rear transport roller device, a shear body, and a roller carrier. The front transport roller device includes a laser scriber, a magnetic alignment device, and a pinch roller device. The rear transport roller device includes a vertical guide roller. The laser scriber is disposed on the front end of the front transport roller device. The magnetic alignment device is disposed in the middle part of the front transport roller device. The pinch roller device is disposed on the rear end of the front transport roller device in front of the shear body. The roller carrier is disposed longitudinally in the middle of the shear body. The vertical guide roller is disposed on the rear transport roller device and behind the shear body.

An apparatus for cutting off concrete, wooden, and/or metal piles, casing, conductor pipe and other metal tubulars, uses a metal frame and a metal blade linearly moveable within the frame, the blade being hydraulically and/or pneumatically driven to puncture and then slice and split through the metal being cut off, the cutting surface of the blade having a removable, centralized puncture point located essentially at the projected intersection between two concave cutting surfaces.

Method for cutting soft metals, comprising the use of a cutting tool capable of being set in motion by ultrasonic vibration. The method is employed for cutting components used in the manufacture of an electrochemical storage device, for example, a lithium battery. These components include the anodes, the cathodes, the solid electrolytes, the current collectors and the separators. The method is also employed in a system for manufacturing and/or characterizing an electrochemical storage device.
