072392000 | BY RELATIVELY RECEDING WORK-ENGAGING TOOL-FACES (E.G., FOR STRETCHING) | 6 |
20100058828 | Cladding Method and Expansion Tool - A cladding method for sealing a leak in a casing, a pipeline, a borehole, or a well downhole using a liner having a tube with a first diameter, a plurality of circumferential grooves, and a plurality of seals in the grooves extending beyond the first diameter. The cladding method has at least the steps of fastening the liner in a fastening mechanism of an expansion tool, inserting the liner having a first part and a second part into the casing outside the leak, positioning an expansion mechanism of the expansion tool at the first part of the liner, expanding the first part of the liner until the seals in the grooves of the first part of the liner are pressed against the casing and fasten the first part to the casing, releasing the liner so that the liner is free of the tool and the liner is held in place by the seals in the first part of the liner, and expanding all the way through the liner by expanding also the second part of the liner to abut the casing for sealing the leak. | 03-11-2010 |
20100107720 | TITANIUM STRETCH FORMING APPARATUS AND METHOD - A stretch-forming apparatus includes a main frame which carries a die enclosure between jaw assemblies. An insulated die is mounted in the enclosure. A method of forming a component includes placing a workpiece in the enclosure, heating the workpiece to a working temperature using electrical resistance heating, and then stretching the workpiece against the die. The method is particularly useful for titanium workpieces. | 05-06-2010 |
20110296898 | MACHINE FOR DRAWING METAL SHEETS - An apparatus for drawing a metal sheet. In one implementation the apparatus includes a fixed head having a first window through which the metal sheet to be drawn may pass and a first holder for holding a first portion of the metal sheet within the first window during a drawing process. The apparatus also includes a moving head that is moveable relative to the fixed head, The moving head has a second window through which the metal sheet to be drawn may pass and a second holder for holding a second portion of the metal sheet within the second window during a drawing process. A support assembly is attached at one end to the fixed head and extends longitudinally through the second window of the moving head. The support assembly forms a part of an actuator assembly that is operable to situate the moving head in different and fixed longitudinal positions relative to the fixed head prior to a drawing process. | 12-08-2011 |
20140041434 | PIPE EXPANDING TOOL - A pipe expanding tool includes levers rotatably connected to each other through a rotary shaft, grips disposed on ends of the levers, jaws disposed on other ends of the levers, and mandrels disposed on the jaws. An adjustment screw for adjusting an angle of rotation of the levers, a lock nut for fixing the adjustment screw, and a stopper that restricts rotation of the levers are further provided. | 02-13-2014 |
072393000 | Embodying three or more tools (e.g., tube expander) | 2 |
20090113979 | EXPANSION TOOL FOR COLD EXPANSION OF HOLES | 05-07-2009 |
20160023262 | TUBE EXPANDER WITH POSITIONING STRUCTURE - A tube expander with positioning structure includes a base, a tube clamp, a positioning device, and an adjusting thread rod. Therein, the base has a body and a neck. The body has a guiding groove and the neck is inserted with a rotating thread rod capable of vertically moving. An expanding cone facing the guiding groove is on one end of the rotating thread rod. The tube clamp having tube bores is slidingly disposed in the guiding groove. The positioning device is on one side of the guiding groove, thereby engaging and positioning the tube clamp and positioning the tube bores under the expanding cone. The adjusting thread rod is pivotally disposed on the body for fastening the tube clamp. | 01-28-2016 |
