A gas turbine nozzle can be refurbished to reduce downstream deflection. The outer shroud of the gas turbine nozzle is held in a fixture, and then the nozzle is heated. The heated nozzle is then reshaped by a force exerted upon the inner shroud of the gas turbine, reducing the downstream deflection of the nozzle. After the deformation of the nozzle, an aft hook of the nozzle that has been adjusted by previous refurbishment efforts can be rebuilt to remove the previous adjustments. |

The invention relates to a gripping head for grasping devices for manipulating a long workpiece in a horizontal arrangement. A gripping head with two clamping jaws which can be adjusted independently of one another can be used. In addition, a device for feeding long workpieces into a processing machine, and discharging them therefrom is proposed. At least one of the grasping devices may have a gripping head for gripping in a frictionally locking fashion one end of the workpiece which is conveyed here by the horizontal conveying means, and drive means for pulling the workpiece to be straightened into the processing section and for pushing the straightened workpiece out onto the at least one horizontal conveying means by means of the gripping head. |

The method of distorting a workpiece (8) includes selecting a desired configuration of the workpiece; determining distortions (14) to be applied to at least two regions of the workpiece to cause the workpiece to adopt the desired configuration; and using the determined distortions in accordance with predetermined information (12,13) relating heat treatments of the workpiece to resultant distortions, to obtain or generate heat control data (15) defining heat treatments to be applied to corresponding regions of the workpiece, which will cause the determined distortions in the workpiece (8). The heat control data and the determined distortions are related by the equation AX=B, where B is a vector describing the determined distortions according to the heat treatments, X is a vector representing the heat control data and A is a matrix of elements representing the predetermined information. The defined heat treatments are then applied (16) to the corresponding regions of the workpiece (8) to produce the determined distortions. |

A method for forming a metal product includes providing a counter stress feature in the metal product that is positioned to balance the stress in the metal product. The method includes providing a metal product having a neutral axis; providing a cutout in the metal product on a first side of the neutral axis; and providing a counter stress feature on a second side of the neutral axis. The position and size of the counter stress feature is predetermined such that the counter stress feature balances the stress introduced by the cutout. An extruded metal product includes a web having a neutral axis, at least one cutout in the web on a first side of the neutral axis, and at least one indentation in the web on a second side of the neutral axis. The at least one indentation is positioned to balance the stress introduced by the at least one cutout. |

A straightening apparatus for large diameter thick wall pipe has an expander head at one end of a beam inserted into the pipe and having a radially displaceable saddle positionable at any selected location along the beam. The saddle may be shifted along the beam by a linear actuator and the saddle applies a radial force to the inner wall of the pipe in a bending operation. |

Method for straightening drawn round stock and apparatus for the

The invention relates to a method and an apparatus for the straightening of drawn round stock. In conventional straightening methods, the round stock to be straightened is transported through the straightener with the entrance and exit in alignment, being thus straightened. With this procedure, large pieces at the beginning and end of the round stock to be straightened are straightened in an unsatisfactory manner and must therefore often be cut off before further fabrication of the round stock. To remedy this disadvantage it is proposed that for instance the deviation from the straight entry line forcibly obtained in the straightener arc by deflection, is maintained as the exit direction from the arc. To this end each round stock receiving device is oriented or can be oriented behind an exit die at least by its receiving elements in such a way that the round stock leaving the exit die enters such receiving elements or the next die series without appreciable changes of direction. |

A tubing sizer and straightener having a first lever and a second lever connected to one another by a linkage which causes the levers to move to and from a position in which the levers are substantially parallel and adjacent to one another. Longitudinally extending jaw parts, one of which is mounted on one of the levers and the other of which is mounted on the linkage, thus move against one another along a common plane when the levers are substantially parallel and adjacent to one another for sizing and/or straightening a length of tubing disposed between the jaw parts. |

A feed channel for elongated workpieces includes a plurality of adjustable workpiece receiving openings. Each opening is formed by a plurality of profiled segments including at least one movable segment. The movable segments are movable to expose the openings for lateral introduction thereinto of an elongated workpiece. The movable segments are then moved to reduce the size of the openings and engage the workpiece for at least partially straightening same. The movable segments are then moved to increase the size of the openings for providing longitudinal and rotational movement of the workpiece relative to the openings. |

SEULEN G; REINKE F |
An improvement in a method of hot straightening workpieces as described in U.S. Pat. Nos. 3,598,665 and 3,631,698 whereby a workpiece is inductively heated and, at the same time, the induction currents in the workpiece generate, together with the inductor current, a force thrusting the workpiece against stops advanced for that purpose. In order to avoid reduction in reverse bending and/or tortional strength, according to the method of this invention the stops are advanced into contact with the workpiece only after at least 75 percent and preferably 85 percent of the total energy required for heating the workpiece has already been supplied.

A metallurgical process for bending steel bars or rods to the desired finished curvature or straightness without the normally expected losses in strength properties by bending the steel to straighten, etc., while at a temperature within the range of 300*-900* F. and preferably 400*-700* F. Steels which respond to such treatment are of the type which precipitation harden in response to such bending.
