Abstract
A tool for severing or crimping a workpiece includes a rigid mainframe having an elongate grooved channel running through most of its length. A wedge-shaped upright rigid head forms the front portion of the mainframe. The rear portion of the mainframe has an integral shaft guideway and a mount for mounting a hydraulic cylinder and components. The head and hydraulic mount form a U-shaped jaws area. The upright head has an elongate vertical slot. A cutting or crimping blade can reciprocate along the grooved channel of the mainframe and enter the head so that the blade can fully sever a workpiece placed in the gap between the blade and head. The blade can be a pointed V-shaped cutting blade or a flat crimping blade having a blunt leading edge. The base of the blade has a flange for cooperating with the grooved channel for guiding the blade. The blade is manipulated by a hydraulic piston which is positioned in a hydraulic cylinder mounted at the rear portion of the mainframe. The hydraulic pressure causes the shaft to extend or retract with the cutting blade attached to it. Additional features include handles to allow the operator to manipulate the tool.
