  • Patent number: 7918630
    Abstract: A material cutting machine has a tool mount support mounted for reciprocal movement and a tool mount supported by the tool mount support. A driver, such as a pneumatic cylinder, selectively advances and retracts the tool mount support. A control system is operatively coupled to the driver for setting the advancement force of the tool mount support when a tool supported by said tool mount contacts a workpiece, such as the edge or surface of a moving strip. In this way, the depth of cut of the tool is controlled by tool advancement force rather than by accurate positioning of the tool. In one embodiment, the tool mount support may have a head and a base and a resilient member resiliently coupling the head to the base to provide a damped resilience. With this embodiment, a transient spike in the reaction force which may result, for example, from a hard spot in the material, causes the tool to momentarily deflect.

  • Patent number: 4624164
    Abstract: A hydraulic shearing machine for cutting steel sheets and the like in which the lower blade is fixed between two vertical end-plates of the frame while the upper blade is carried by a movable apron. The support provided for the lower cutting blade consists of a hollow box which extends horizontally between the vertical end-plates of the shearing-machine frame and only the ends of which are attached to the frame. The lower blade is fixed against one of the side walls of the support box so as to be displaced with respect to the theoretical center of rotation of said support box about its own axis. In consequence, the vertical forces exerted on the lower blade at the time of utilization of the shearing machine tend to produce a twisting movement of the support box, thus providing compensation for the horizontal flexural displacement of the box under the action of the horizontal forces.

    Abstract: Web cutting apparatus employs a rotary knife cylinder with elongated, radially outwardly projecting knife blade assemblies spaced around its periphery. A rotary anvil cylinder spaced parallel to the knife cylinder carries a corresponding peripheral array of elongated anvils. When the two cylinders rotate, the knife blades bear against the anvils at the nip between the two cylinders. The knife blade assemblies are flexible and resilient so that each blade edge is biased against its anvil at the instant of interference, with a local force sufficient to cut web. Further, the natural frequency of the knife assemblies is selected to be considerably higher than those of the other machine parts so that the spacing between the knife blades and the anvils at the nip is substantially unaffected by vibrations of those parts. Also the apparatus efficiently removes trim strips produced by the web cuts.
