    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.

  • Patent number: 4470330
    Abstract: A tooling assembly for use with a mechanical impact press includes a pair of die blocks which effect cutting of rods, bars and tubes by the rapid misalignment of aligned apertured tools. Realignment is achieved by a reciprocable cam which also limits the extent of misalignment. Means are provided for clamping or dragging the end of a workpiece stock upstream from the prospective cutting plane. A wedge shaped recess adjacent to the aperture of the movable tool or die block provides a high degree of uniformity in workpiece length as measured at various points of a given workpiece. Where the workpiece stock is tubular, a floating mandrel is disposed within the workpiece in the upstream tool or die block while a reciprocable mandrel supports, receives, resizes and discharges the tubular workpiece.

  • Patent number: 4302996
    Abstract: A method and apparatus for detecting the length of wire blanks in a wire cutting machine is disclosed, the machine including feed apparatus for feeding wire stock into the cutting machine, stop apparatus for engaging one end of the wire stock at a predetermined length in the cutting machine, and cutting apparatus for cutting wire blanks from the wire stock. When the leading end of the wire stock engages the stop apparatus with a predetermined pressure, the blank is at a proper length to be cut. The pressure causes the stop apparatus to expand radially. Strain gauges mounted about the stop apparatus detect the expansion by generating an electrical signal when connected in a bridge circuit. The strain gauges detect an over feed situation when the stop apparatus expands beyond a predetermined point. Similarly, an under feed situation is detected when little or no expansion of the stop apparatus is sensed.

  • Patent number: 4283974
    Abstract: A bar end dropper for forging machines or the like is disclosed which automatically operates to reject blanks cut from the end of the piece of stock which are of unsatisfactory length and to adjust the feed when necessary to ensure that the ends of pieces of stock being fed into the machine are a sufficient distance from the shear plane of the cutter to ensure a clean cutting operation. As sequential pieces of stock are fed to the machine, they are positioned in the measuring position and the measuring carriage moves in to position a sensor a distance from the shear plane determined by the length of the stock. This automatically positions the sensor.
