  • Publication number: 20040079212
    Abstract: A mandreled tube punch includes a cantilevered mandrel and an arbor housing for securing the cantilevered mandrel. The cantilevered mandrel has a bore longitudinally disposed therethrough and the mandrel is adapted to secure a workpiece, or tubular stock, to be punched. An evacuation apparatus in the form of a pushrod is disposed within the longitudinally disposed mandrel bore and is arranged for movement therein and removes punched material from the work area. The punching device further includes a punching means for punching the workpiece and includes a punch housing having an aperture that accepts the workpiece positioned on the mandrel. The punch assembly prevents the workpiece from becoming damaged as a result of punching operations and efficiently, effectively and safely removes punched material from the work area.

  • Patent number: 5699708
    Abstract: The invention provides a punch press capable of impressing a plurality of holes or other changes in a workpiece. The central core piece of the punch press receives the workpiece and expands until it touches the inner walls of the workpiece. This holds the workpiece in place and prevents any workpiece movement or distortions in the holes formed because of movement of the workpiece. Hydraulic cylinders impel the plurality of punches toward the workpiece at substantially the same pressure and time.
