Abstract: A method and apparatus achieve the intermittent feeding of raw material into a shearing station by exerting a drive torque on draw-in rollers in order to effect their rotation in one arcuate direction and hence the movement of the raw material toward the shearing station. A counteracting torque, which is less than the drive torque, is continuously exerted on the draw-in rollers. Thus, during intervals following a shearing operation when the drive torque is terminated, the counteracting torque functions to reverse the rotation of the draw-in rollers and hence retract the sheared end of the raw material away from the shearing station.

The described arrangement produces an elliptical loop movement of the movable die relative to the fixed die to cleanly shear the stock. Also disclosed is a novel mandrel assembly including a pair of plug members adapted to be positioned within tubular stock to be cut wherein one of the plug members is mounted for selective radial excursion during the shearing operation to accommodate the eccentric movement of the movable die.

Abstract: In shears for rod-form material, especially in connection to roll trains, the problem exists of a space-saving construction, especially in the sidewise direction, in view of the multiple arrangements, as well as increased safety (reliability) of operation for the high-pressure hydraulic system of the cutting drive.The shear provided with two knife holders (MT1, MT2) and a fluid drive element (ZK) as well as a respective pressure feeding device (DS), is so designed, for this purpose, that the pressure work chambers (DA1, DA2) of the drive element, such as a double-acting cylinder-piston arrangement, and the elements carrying pressure fluid (high-pressure pumps, etc.) of the pressure feeding device (DS) are designed to be movable in common with a knife holder (MT1) which is movable in relation to the machine frame or a conduction (SF) of material to be cut, and preferably fixed in space with this latter (MT1).

Abstract: A shear for cutting bar stock includes upper and lower cutting blade supports each having a cutting blade, and a hold-down member, all pivotally connected about a working bearing. This assembly is pivotally mounted about a second bearing or pivot axis on one end of a frame of the shear, and is height-adjustable by a lockable hydraulic actuator attached to the upper cutting blade support at the opposite end of the shear, to provide vertical adjustability of the cutting point with minimal horizontal or angular displacement thereof. Preferably, the two pivot axes and the cutting point are coplanar. The upper cutting blade support is pivoted relative to the lower one by a hydraulic actuator engaging the upper support at one upper part thereof which is not so coplanar, to provide both a relatively long lever arm and a relatively long cutting arm for minimizing arcuation of the cutting movement. One cutting blade is adjustable within its support for optimum positioning taking into account the shape of the stock.

Abstract: A method of shearing a workpiece, for example a metal billet or bar, and apparatus for carrying out that method. Before being subjected to linear shear, the billet is first subjected to substantial torque about an axis perpendicular to the plane of shear. The billet is held by two pivoting arms, the predominant torque of the first stage of the method is achieved by allowing the pivot points of the arms to slide as the arms turn, and the predominant shear of the second stage is then achieved by arresting that sliding movement by stops. The parts of the arms which grip the workpiece may bear against a fixed surface during the whole operation, so holding the axis of the workpiece to a constant location.

Abstract: An automatic capacitor winding machine has a retractable bifurcated arbor and vertically movable clamps to grasp the ends of the capacitor dielectric layers and carry those ends to a point below the retracted arbor. The bifurcated arbor is registered in its retracted state with its slot parallel to the dielectric layers. The arbor is then extended and grasps the dielectric layers between its tangs. The pressure grasping the dielectric layers is partially removed to allow the arbor to rotate and pull the dielectric layers from between the clamps. A stripper washer is provided to freely rotate on the arbor with limited movement parallel to the axis of the arbor and with a relatively small clearance between the washer's inside surface and the arbor's outside surface. Photoelectric means are provided to accurately detect the location of the first tab (terminal) to time the insertion of the other tabs. A reciprocating blade severs the dielectric layers after the capacitor is wound.
