  • Patent number: 7275403
    Abstract: A rain gutter roll forming machine wherein the final forming station has the exit drive rollers removed therefrom. The forming rollers for the lower front and back corners of the gutter are mounted for rotation about a single substantially horizontal axis and are supported by a camber adjustment plate. The camber adjustment plate is pivotable about a pivot point which is substantially within the plane of the bottom wall of the gutter. Accordingly, the relative pressures applied to the gutter by the corner forming rollers can be varied to compensate for longitudinal curvature of the gutter due to differential drag on the front and back gutter walls.

  • Patent number: 7269989
    Abstract: A method of using a tool for punching orifice that has wall surfaces extending at an angle relative to a generally planar surface of a workpiece. The method includes sequentially forming two spaced apart impressions formed in the workpiece between first and second generally planar surfaces spaced apart along a longitudinal axis of the workpiece. The two spaced apart impressions form a first orifice wall surface disposed at an obtuse angle with respect to the generally planar surface facing the tool and a second orifice wall surface disposed at an acute angle with respect to the generally planar surface, and coincidental with the punching process, a retention arrangement that secures the workpiece during the forming of the orifice.

  • Patent number: 7263866
    Abstract: The golf club hosel bending fixture immovably secures a golf club head therein in order to adjustably bend the hosel angle of the club head to “fine tune” the characteristics of the club. The fixture includes an angularly articulating crown jaw assembly, a relatively fixed lower jaw assembly generally opposite the crown jaw assembly, a longitudinally disposed back jaw assembly, and a club head face jaw disposed at the base of the crown jaw track in order to remain aligned with the crown jaw. The jaw clamp and base mechanisms are laterally symmetrical, in order to provide for both left- and right-hand club heads. Two orthogonal gauges are provided to check both loft and lie angles of the hosel relative to the club head and face. The gauges may be adjustably positioned to either side of the fixture, to check either left- or right-hand club heads.

  • Patent number: 7254974
    Abstract: The present invention is a bending machine for bending material such as steel to form cutting dies for products such as cloth, leather or the like. Coiled material is fed through a material washer, straightener and printer by a material feeder to a bending head. If required the material is forwarded through the bending head to a heating unit and retracted to the bending unit to aid in bending. A nicking tool is also provided ahead of the bending tool to nick the material. The nicks enable the cutting die to cut notches in the product being cut. A support surface at the output end of the machine supports the material as it is bent into the required form.

  • Patent number: 7251979
    Abstract: A method of producing a forged part includes holding a material by a jig, upsetting the material, held by the jig, to a predetermined length by a pair of upsetting dies disposed on both ends of the material, while pressing the upsetting dies on the material, so as to produce large-diameter portions at the respective axial ends of the material. Next, a bending operation and a forging operation are made to the upset material, in that order. When forging, a direction, in which the material is forged, is set, so that a burr generated on the material by upsetting is included in a burr generated on the material by forging. Next, a finish-machining operation is made to the forged material to remove the burr left on the outer periphery of the material after forging. Thereafter, the finish-machined material is drilled to form bush-mounting holes in the large-diameter portions.
