| 20080302775 | METAL FORMING APPARATUS AND PROCESS WITH RESISTANCE HEATING - An apparatus for forming a metal article includes a station which receives and supports a workpiece. The station has a source of electrical current and a source of a fluid. The station further includes a first and a second electrode clamp. Each clamp is in electrical communication with the source of current and in fluid communication with the source of fluid. The clamps engage a workpiece and deliver an electrical current and a fluid thereto. The system includes an actuator mechanically associated with at least one of the clamps. The actuator is operable in combination with a clamp to apply mechanical force to the workpiece. The system is operable to selectably control the temperature profile and/or ambient conditions of a workpiece during forming or processing steps. Disclosed are specific systems including modular systems. Also disclosed are methods for using the systems. | 12-11-2008 |
| 20090152256 | METHOD FOR MANUFACTURING A STAMPED/HEATED PART FROM A STEEL SHEET PLATED WITH ALUMINUM ALLOY - A method and related apparatus are disclosed for heating and stamping a processed part. A sheet of high-tensile steel is provided as a work part. The sheet is plated with a high-temperature-resistant material to improve formability. The temperature-resistant material can include oxidized aluminum or a high-temperature-resistant alloy of aluminum and/or zinc and/or steel. An electrical current is applied to the work part to provide heating to the work part through resistance heating. The plated sheet can be stamped while heating to form a stamped work part. The work part is quenched through cooling to increase metallurgical strength. | 06-18-2009 |
| 20140014639 | Method for Manufacturing a Part Having a Complex Shape by Flash Sintering, and Device for Implementing Such a Method - The invention relates to a method for manufacturing a metal, ceramic, or composite part (PF) by flash sintering, which comprises simultaneously applying, inside a die (M), a uniaxial pressure and an electric current to a device containing a powder constituent material, said uniaxial pressure being applied by means of at least two pistons (P | 01-16-2014 |
| 20140312024 | METHOD FOR PRODUCING STEEL SHEET FOR PRESS MOLDING, AND METHOD AND DEVICE FOR PRODUCING PRESS-MOLDED COMPONENT - [Problem] To provide a method for producing a non-rectangular steel sheet to be heated to the predetermined temperature, a method and apparatus for producing a press-molded article using the non-rectangular steel sheet for press molding that is produced by means of that method for producing the same. | 10-23-2014 |

| 20120298648 | CRIMPING METHOD AND CRIMPING SYSTEM - A crimping method including the steps of: holding a workpiece comprised of a main body disposed around an outer circumference of a tubular shell in a first die; placing a second die for wrap crimping at a position facing the first die across the workpiece and moving the second die towards the first die to press the rim of the shell and plastically deform the rim to form a wrap crimped part; and bringing hot crimping-use electrodes arranged at sides of the shell, in a state holding the workpiece between the first die and the second die, into contact with side surfaces of the shell to apply current between the electrodes and the first die and make a thin-walled part to generate heat by resistance heating to thereby form a hot crimped part. | 11-29-2012 |
| 20150060427 | BLANK FORMING DEVICE USING ELECTRIC DIRECT HEATING AND METHOD OF MANUFACTURING A BLANK - A method of manufacturing a blank which uses direct electric heating includes: pressing electrodes on both sides of the blank and heating the blank by applying current to the blank; hot-forming the heated blank; trimming the formed blank; and loading the trimmed blank. An apparatus for manufacturing the blank includes a pair of first electrode units on both surfaces of a side of the blank to press the surfaces, a pair of second electrode units on both surfaces of the other side of the blank, a pressing unit pressing the first electrode units or the second electrode units on the blank, a cooler cooling portions around the first electrode units or the second electrode units, and a power supply control unit heating the blank up to a predetermined temperature. | 03-05-2015 |
| 20150096967 | FEEDSTOCK BARRELS COATED WITH INSULATING FILMS FOR RAPID DISCHARGE FORMING OF METALLIC GLASSES - The present disclosure is directed to feedstock barrels comprising thermally and electrically insulating films configured to be adjacent to a feedstock sample when it is loaded in the barrel for the process of shaping metallic glasses by rapid capacitor discharge forming (RCDF) techniques. | 04-09-2015 |
| 20160136712 | HEATING METHOD, HEATING APPARATUS, AND HOT PRESS MOLDING METHOD FOR PLATE WORKPIECE - A heating method, a heating apparatus, and a hot press holding method for a plate workpiece are provided. The plate workpiece has a first region and a second region. A cross sectional area of the first region in a widthwise direction of the plate workpiece is substantially uniform along a longitudinal direction of the plate workpiece or is monotonically increased or decreased along the longitudinal direction. The second region is adjoining a portion of the first region in a monolithic manner. The method includes heating the second region, and heating at least the first region by direct resistance heating along the longitudinal direction. The second region is heated before heating the first region such that the first region and the second region are heated to be in a given temperature range. | 05-19-2016 |
