    Abstract: A table saw having a rotation structure includes a work table, a suspension rod, a swing seat, a rotation seat, a push lever, two torsion springs, and a threaded rod. When the threaded rod is rotated, the push lever is displaced horizontally to push the rotation seat to rotate, so that the circular blade is moved upward, thereby adjusting the cutting height of the circular blade. Thus, the push lever is urged by the elastic force of the two torsion springs, so that the push lever is closely and rigidly combined with the threaded rod, thereby eliminating the clearance between the push lever and the threaded rod, so that the cutting height of the circular blade is adjusted exactly and precisely, thereby enhancing the cutting efficiency of the table saw.

  • Patent number: 6692424
    Abstract: A rotary trimmer apparatus and signature trimming method are provided that enable operators to set a gap spacing between a rotating knife and an anvil at different predetermined sizes in an easy and accurate manner. The operator chooses the optimum knife/anvil spacing that produces a scissors-like cutting action on the particular type of signatures being trim cut and which does not cause premature knife dulling. The selected knife/anvil spacing is readily reproducable for future runs with the same operating conditions. This is true regardless of changes in the knife thickness as can be created by sharpening thereof, or knife replacement. For this purpose, a user operated control assembly including a control knob and calibrated indexer are provided. To keep the knife/anvil spacing at the set size during trim cutting operations, a temperature control system is employed that keeps axial expansion of the knife spindle shaft from reducing the gap size.

    Abstract: A wire chopper module for processing spent electrode emerging from an EDM system employs replaceable inserts that are also movable relative to the feed path of the electrode. Shifting the position of the inserts relative to the feed path of the electrode allows more than one portion of each cutting edge on the insert to be used. Each insert has more than one cutting edge and can be rotated and re-inserted to present a completely new cutting edge. Removable multi-edge inserts that are repositionable relative to the feed path of the spent electrode permit renewal of the cutting edges of the wire chopper module with increased frequency and reduced cost. The wire chopper module also incorporates a flywheel to increase the moment of inertia of the rotating cutting inserts as an aid in overcoming jams. Sharp cutting edges and increased rotational momentum improve the reliability of the inventive wire chopper module.

    Abstract: A machine tool has a work table which defines a working surface and has a cutting tool which is attached to and movable with respect to the work table. The position of the cutting tool with respect to the working surface is controlled by a mechanism which elevates the cutting tool with respect to the working surface and angulates the cutting tool with respect to the working surface. The cutting tool is mounted to a support plate which is pivotably attached to the work table. The elevating mechanism includes a threaded rod and a nut which engages a pivoting link. The pivoting link also engages the cutting tool. Rotation of the threaded rod pivots the link which in turn raises and lowers the cutting tool. A spring biases the cutting tool towards its lower position to remove play between the components. The angulating mechanism includes a lever, two cams and a locking rod. Rotation of the lever moves the locking rod longitudinally due to the action between the two cams.

  • Patent number: 6263775
    Abstract: One rotary knife carrier of a pair of carriers in a cross cutter for running webs of paper, cardboard or the like has longitudinally extending peripheral recesses for disposable elongated strip-shaped knives each of which has a first lateral surface abutting and slidable along a supporting surface of the carrier in the respective recess, and a second lateral surface contacted by a retaining surface of an elongated clamping member which is urged against the second lateral surface by the head(s) of one or more tensioning bolts having shanks extending with clearance through openings in the clamping member and into tapped bores in the carrier. The clamping member is in form-locking frictional and/or mechanical engagement with the knife and is shiftable relative to the carrier to adjust the knife, e.g.

  • Patent number: 6244151
    Abstract: An improved adjusting apparatus for a cutting bar received in an axial slot of a blade cylinder for cutting web material. The improvement enables an operator to adjust the tilt of the cutting bar relative to the axis of rotation of the blade cylinder to accommodate out-of-parallel conditions in the blade cylinder or mounting slot so that the cutting edge of the blade held by the cutting bar is parallel to the surface of an adjacent anvil cylinder, which supports the web being cut.
