  • Patent number: 8511131
    Abstract: A cable bending tool comprises a drive housing including a powered drive element. A jaw assembly comprises first and second jaws hingedly connected to one another. The drive element is selectively operated to cause the first and second jaws to move between a neutral and an actuated position. A bending shoe is secured to a distal end of the first jaw. An arm with opposite rollers is secured to a distal end of the second jaw and extends transversely to a path of movement of the jaws. The rollers support a cable with the bending shoe on an opposite side of the cable.

  • Patent number: 7658090
    Abstract: A grid bending machine is provided for bending a workpiece. The machine includes first and second guides having inner surfaces defining a cavity therebetween. A stationary anvil is mounted to the first and second guides. A first die is releaseably connected to the stationary anvil. A body is disposed in the cavity and is movable between a first position release position and a second bending position. A second die is releaseably connected to the body and is aligned with the first die. The second die is axially spaced from the first die with the body in the release position and is adjacent the first die with the body in the bending position.

  • Publication number: 20100024514
    Abstract: It is difficult to bend materials for forming beyond 180° in terms of bend angle due to the entrant nature of prior press forming arrangements including a press tool with a press recess of a static nature. By providing a press recess which is formed from actuators allowed to dynamically shift about a deflection member it is possible as a press tool engages and forces a material to be formed into the press recess to envelope the press tool and therefore achieve greater than 180° bending angles. The actuators are formed in a stack with alternate left right presentation of shaped receiving apertures which include an actuator surface 34 engaged by the material to be formed in order to cause the necessary deflections during the pressing process.

  • Patent number: 7624612
    Abstract: An angle adjuster for a golf club shaft includes a pressing part that can advance and retreat towards and away from a space between two pressing force receiving parts. The pressing force receiving parts include grooves configured to receive a golf club shaft. When the pressing part is advanced against the golf club shaft, a bending force is applied to the shaft at a bending location on the shaft that lies between the pressing force receiving parts. This occurs while the shaft is received in, the receiving grooves of the pressing force receiving parts.

  • Patent number: 7596982
    Abstract: An apparatus (100) or repairing dented bearing cages (50) comprises: a first contact surface (122) for contacting an outer diameter of the bearing cage (50); a second contact surface (126) for contacting an inner diameter of the bearing cage (50); a first handle (102); a second handle (104) operatively connected to the first handle (102) via a pivot mechanism (106); a retraction element (108) connected to the second contact surface (126); and an adjustment mechanism (116). The retraction element (108) retracts upon movement of the second handle (104) relative to the first handle (102) to move the second contact surface (126) towards the first contact surface (122) so as to impart a force against a dented region of the bearing cage (50) located between the second contact surface (126) and the first contact surface (122).

  • Publication number: 20090158806
    Abstract: Method for bending tubular articles with a relative ratio of the bending radius (R) and the outer diameter (D) of the finished pipe which is less than 3, comprising the following steps: forging an article made of material with a predefined composition depending on the final use and with a predefined length (L) in the longitudinal direction and an outer diameter (D); providing a die having an asymmetrical bottom die half with seat for the pipe; and a top die half with punch asymmetrically arranged in the longitudinal direction (X-X) with respect to the vertical centre axis of the die; heating the article in an oven to the required temperature for forging depending on the specific composition of the material; positioning the article inside the bottom die half in the longitudinal direction; closing of the two die halves so as to start bending of the article; opening the die; and extracting the bent article.
