| 184 | Stress free steel and rapid production of same | US10993096 | 2004-11-19 | US20050115646A1 | 2005-06-02 | Franklin Stebbing |
| A method of producing steel with reduced internal stress concentrations is disclosed. In an embodiment, hot steel is shaped by a rolling mill. The resultant steel product is bundled as soon as practicable and the bundle is allowed to cool. Vibration energy is applied to the bundle of steel product so that internal stress concentrations within the steel product are relieved. In an embodiment, a plurality of bundles are stored on a rack and the rack is vibrated, the vibrations being transmitted to the plurality of bundles so that undesired internal stress concentrations within the steel products are relieved. Thus, improved steel is produced as well as improved steel that can be produced more rapidly than known techniques. | ||||||
| 185 | Method and apparatus for distorting a workpiece | US10485646 | 2004-05-17 | US20040237622A1 | 2004-12-02 | Ole Runar Myhr; Borge Bjorneklett |
| The method of distorting a workpiece (8) comprises 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 AXnullB, 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 using high interior pressure to reshape structural section of continuously bounded overall cross-section, whereby the overall cross-section can be provided with extra walls or chambers and a stopper is forced radially against each end of the piece. The object is to reduce wear on the stopper while ensuring that any walls or chambers in addition to its overall cross section will buckle or bulge only at their ends. Either any walls (2 & 3) that partition the chambers (4, 5, & 6) and any independent wall (7) are provided with slots (17) at the ends of the piece that parallel the inner surface (18) and outer surface of the piece or the stopper (8) itself is provided with grooves (19) adjacent to and matching the shape of the walls. | ||||||
| 187 | Shaft straightening and hardening machine and workpiece holder therefor | US09541518 | 2000-04-03 | US06308547B1 | 2001-10-30 | Karl Heess; Karlheinz Schweikert |
| A shaft straightening and hardening machine, including a holder for a shaft-shaped workpiece, which can be pivoted around an axis which is essentially parallel to the axis of the workpiece. The machine includes a controllable rotary drive for the holder and a coolant bath through which the holder passes as a part of its path of rotation. The holder includes at least one straightening mechanism, which is mounted at a specified point over the length of the workpiece and which acts radially upon the workpiece and can be swung sideways from said workpiece for the purpose of loading and unloading the workpiece. The holder includes several parallel straightening shafts between which the workpiece can be inserted and from which it can be removed. The end face of each straightening shaft is held in a bearing bracket, and one of the straightening shafts can be swung radially sideways. The straightening shafts have radially protruding profiling that act as the straightening elements or mechanisms. | ||||||
| 188 | Binding structure for multiple small and thin pipes | US32772 | 1998-02-28 | US5943903A | 1999-08-31 | Shao-Chien Tseng |
| A binding structure for multiple pipes includes a plurality of disks with holes to receive the pipes. The holes are offset on alternating disks so that the pipes are securely held between the multiple disks. Latching pins are used to fix the disks in position after the desired placement of the pipes is achieved. | ||||||

| Method and apparatus for the surface working and for reworking, or reshaping, of elongated workpieces. A strike bolt strikes the inner side of the curvature of the workpiece at high frequency to apply a plurality of strikes to the workpiece. Measurement of the straightening of the curved workpiece occurs directly on the worktable, preferably by means of air-jet nozzles, which are connected to indicating tubes. | ||||||
| 190 | Planetary straightening machine | US669478 | 1976-03-23 | US4037447A | 1977-07-26 | Sheldon E. Sampson; Don A. Cargill |
| A planetary production workpiece processing machine having a rotatable annular drum with circumferentially extending planetary workpiece engaging tooling and opposed fixed reaction tooling providing a progressively variable relative radial tooling spacing for rolling and variably stressing the planetary workpiece beyond elastic limit as it progresses from an entrance to an exit portion of the machine. Processing operations may include straightening of linear workpieces with rapid and gradually reduced deflection or progressive reduction forming of the workpiece. Multiple diameters in a linear workpiece are accommodated through the use of free floating as well as power driven drum elements. | ||||||

| This disclosure shows a machine for bending and/or twisting a beam. The machine has a frame with a guide for the beam at each end. A twisting device in the form of a rotatable drum is supported on the frame and clamped to the beam and a calibrated scale is fixed to the frame to measure the amount of twist. A carriage is movably supported on the machine frame and can be clamped to the beam to advance the beam along the frame and to bend it.
