| 20090071221 | Mandrel Bar for High-Alloy Rolling, Method for Surface Treating a Mandrel Bar, Method for Producing Mandrel Bar, and Method for Operating Seamless Pipe Mill - A method for surface treating a mandrel bar used for hot rolling of high-alloy seamless steel pipe is provided. The method includes heat treating the mandrel bar to develop a scale, and after heat treatment, rolling ordinary steel comprising 8% or less of chromium for at least 50 passes. This achieves a mandrel bar for rolling high-alloy steel possessing both durability and superior resistance to seizure | 03-19-2009 |
| 20120000267 | MANDREL ASSEMBLY FOR TUBE BENDING - The various embodiments herein provide a mandrel assembly for tube bending. The mandrel assembly comprises a plurality of chains, a ring arranged between the plurality of chains links, a plurality of ball segments, a shank and a pin. The ring is placed between the set of chain links and the chain links are inserted into the one side of the ball segment and the other side of the ball segment is inserted with other set of chain links and the pin is held to hold the components firmly. The plurality of chains links are passed into a machined section of each of the plurality of ball segments and the pin is inserted into a groove of the ball segments to hold the plurality of chains and then connected to the shank thereby forming a mandrel joint. | 01-05-2012 |

The work support is arranged in the region of the die, and the spring force of the spring element is adjustable. | 04-16-2009 |
| 072466800 | Resilient material | 4 |
| 20080271513 | CURVED SURFACE FORMING APPARATUS, OPTICAL SCANNING APPARATUS, AND IMAGE FORMING APPARATUS - A curved surface forming apparatus includes a first member to be curved; a second member which is placed with a distance from the first member and holds the first member; and a pressurizing mechanism which pressurizes the first member and the second member to curve at least a part of the first member toward at least the second member. | 11-06-2008 |
| 20090071222 | METHOD OF BENDING PIPE MATERIAL - In a bending method of bending a pipe material of metal in pipe working, at first particles are fed into a flow passage of the pipe material, the particles being removable in a liquid phase. The pipe material with the particles is bent. The particles in an at least partially liquid phase are removed from the pipe material, to clean the flow passage. The particles are meltable, or soluble in dissolving liquid. Specifically, in the removing step, the dissolving liquid is supplied into the flow passage, the particles are dissolved in the dissolving liquid, and compressed air is blown in the flow passage to eject the fluid obtained by dissolving the particles in the dissolving liquid. The particles are granulated sugar, and the dissolving liquid is warmed water. | 03-19-2009 |
| 20090090162 | Driver plate for electromagnetic forming of sheet metal - A multi-layer driver plate is disclosed for use in electromagnetic sheet metal forming operations. In one embodiment, the driver plate comprises a first layer characterized by low electrical resistivity and thickness for inducement and application of a suitable electromagnetic forming force, a second layer comprising an elastomeric material for compressing a sheet metal workpiece against a die surface and then regaining its original pre-forming structure, and a third layer interposed between the first layer and the second layer to protect the EMF force providing layer and to provide overall strength and durability to the EMF driver plate. | 04-09-2009 |
| 20090293579 | NET-SHAPED DUCT FORMING APPARATUS AND METHOD - A duct-forming apparatus includes an apparatus frame, a forming piston assembly having a cylinder carried by the apparatus frame and a forming piston extendable from the cylinder. A duct-shaping assembly includes a form die having a form die interior and a forming surface provided in the form die interior; a forming assembly having a plurality of expandable forming sections provided in the form die adjacent to the forming surface; and a plurality of piston openings provided in the expandable forming sections, respectively, and adapted to receive the forming piston of the forming piston assembly. A duct-forming method is also disclosed. | 12-03-2009 |
