Work Feeder Mounted On Tool Support Patents (Class 83/322)
  • Patent number: 9457488
    Abstract: A blade mount is attached or detached without bolts to save the time for the attaching and the detaching. Consequently, the operation efficiency of the rotary die cutter is enhanced, which is intended to achieve. Two fixing rings are freely fitted to a knife cylinder and the driving unit rotates the screw axis to move moving mounts. Thereby, yoke plates disposed on the moving mounts move the fixing rings to the end portion of a blade mount, and then an activated unit activates fixing units to fix the fixing rings to the outer circumference face of the knife cylinder, so that the blade mount is fixed. After the fixing rings are fixed, the yoke plates are separated from the fixing rings, so that abrasion of the yoke plates can be avoided.

  • Patent number: 5572917
    Abstract: An apparatus for perforating corrugated tubing is disclosed. The apparatus receives tubing to be perforated along an axial path coincident with the axis of the tubing. A plurality of feeder-cutter wheels drive the tubing through the apparatus and concurrently perforate the tubing in the valley of its corrugations. Each feeder-cutter wheel, and the drive shaft each wheel is mounted upon, is offset at an angle relative to the axial path, this angling facilitating uniform perforations at higher speeds. An alternate embodiment of the apparatus has six feeder-cutter wheels disposed within four distinct planes. This design permits the wheels to be interchangeable with different wheels, allowing the apparatus to perforate tubing of different diameters. The alternate embodiment also offsets the wheels at an angle to facilitate perforation at high speeds than previously known in perforating apparatus.

  • Patent number: 4494427
    Abstract: A rotating shear for cutting a rapidly moving wire has a pair of cutter heads rotatable about parallel axes and having respective blades. A drive synchronously counterrotates the heads about the respective axes with close juxtaposition of the blades on each revolution. Thus when the wire is between the heads level with the blades it is severed thereby. A guide tube surrounds the wire upstream of the heads and has a downstream end movable generally parallel to the axes and positioned adjacent and between the cutter heads. The wire exits from the guide tube in a direction generally perpendicular to the plane of the head axes. A guide head fixed to one of the cutter heads is formed with a generally helical guide groove centered on the respective axis. An axially and radially displaceable but angularly generally nondisplaceable follower can move between a position engaged in the groove and axially entrainable thereby and a position clear thereof. An actuator displaces the follower between the positions.

  • Patent number: 4483379
    Abstract: The machine automatically pivots itself into alignment with the orientation of a log being drawn into the machine, and/or pivots the log, and is vertically adjustable to conform to the inclination of a log in process. To cut off an end piece of the log, a shear blade first makes a partial stroke cutting less than entirely through the log. Then the shear blade frame moves away from the input end of the machine, pulling in another length of log. Then the first cut is completed and the shear blade and shear blade frame retract to starting positions for the next cut. This cycle is repeated in automatic operation. When splitting is desired, as for firewood, the shear blade is utilized as a ram to force each end piece of the log through a splitter at the output end of the machine.
