| 20090320544 | COILING FURNACE - A coiler furnace having a heat-insulated enclosure delimiting a furnace interior, a strip coiling device includes a coiler drum having a slotted receiving opening for the hot-rolled strip in the furnace interior. A controlled rotational drive for a coiler shaft is located outside the furnace interior. An inlet and outlet opening to the enclosure for a hot-rolled strip. A strip guiding device between a roller table and the coiler drum. In order to avoid any winding errors, a feeding shield extends through the enclosure of the coiler furnace and is coupled to a displacement drive arranged outside the furnace interior. The displacement drive can be displaced between an insertion position and a withdrawal position of the shield. The feeding shield, in the insertion position, interacts with the strip guiding device to form a feed funnel, mounted upstream the slotted receiving opening on the coiler drum for the hot-rolled strip together. | 12-31-2009 |
| 20100218577 | THREE-DIMENSIONALLY BENDING MACHINE, BENDING-EQUIPMENT LINE, AND BENT PRODUCT - A three-dimensionally bending machine comprises a supporting unit to support a workpiece and a feeding unit to feed the workpiece from an upstream side of the workpiece. A heating and cooling unit, provided around the outer circumference of a portion of the workpiece downstream of said supporting unit heats the portion of workpiece in a temperature range for plastic deformation and quenches and rapidly cools the deformed workpiece. A three-dimensionally movable unit, provided downstream of said heating and cooling unit, supports the metal material and controls the supporting position and/or the moving speed of the metal material to apply the bending moment in association with a feed amount, a heating amount, and a cooling amount of the workpiece. Even when a high-strength workpiece is bent, a workpiece having excellent shape fixability and uniform hardness distribution can be made, especially for application to sophisticated automobile parts. | 09-02-2010 |
| 20100300169 | DEVICE AND METHOD FOR BENDING PIPES - A device for bending a pipe includes a pipe feed device configured to continuously advance the pipe in a longitudinal direction of the pipe feed device; a bending arm pivotable about a rotation axis and having a pipe holding device securable on the bending arm in a first fixing position and in a second fixing position, the first fixing position disposed on the other side of a centre axis of the bending arm from the second fixing position, the pipe holding device configured to detachably secure the pipe, wherein the feed device and the bending arm are movable relative to one another such that the feed device and the rotation axis can be moved past one another; and a heating device disposed in a pipe feed direction and configured to heat an area of the pipe. | 12-02-2010 |
| 20120186317 | Finish-Rolling Device, As Well As Method For Manufacturing A Magnesium Strip In Such A Finish-Rolling Device - A finishing rolling device for manufacturing a thin magnesium strip based on a coil fed to the device includes a roll stand for accommodating at least two working rolls ( | 07-26-2012 |
| 20120198902 | METHOD AND DEVICE FOR COMPLEX FORMING A METAL SHEET BY MEANS OF BODIES OF REVOLUTION - A metal sheet is formed by passing it between a pair of closely spaced shaped bodies fixedly mounted on driving shafts by intermediate pieces which limit the angular portion of the circumferences of the shaped bodies with which the sheet comes into contact. The configuration of the surfaces of the shaped bodies define the respective top and bottom surface configurations imparted to the sheet by being passed between the rotating shaped bodies with pressure, and, optionally, heat. The direction of rotation of the shaped bodies is reversed, without the application of pressure to the sheet, to bring the sheet back to a starting position for each repeated pass of the sheet through the shaped bodies thereby to progressively change thickness and/or shape of the sheet. | 08-09-2012 |
| 20120227455 | MAGNESIUM ROLL MILL - A magnesium hot rolling mill system including a rolling mill having at least two work rolls for rolling of magnesium sheet or plate, a hot coiler positioned on either side of the rolling mill for heating and maintaining a desired temperature of the magnesium sheet or plate, active thermal roller tables, a mill drive system for independently driving the work rolls for asymmetrical rolling of the magnesium sheet and a warm coil loading and payoff station. | 09-13-2012 |
| 20140373587 | Portable Rotary Tube Straightener Apparatus - A portable rotary tubing straightener apparatus comprises a mobile console with spool mounting assembly. A motor is supported on the console and drives a shaft which mounts a drive roller. An adjustable tensioner assembly has a tension roller positionable opposite the drive roller. The drive and tension rollers are engageable at opposed locations of a continuous tubing. A rotary straightener assembly is disposed on the console. A motor carried by the console is activatable to rotate the rotary straightener assembly. A spool with metal tubing is mounted to the spool mounting assembly and passes tubing through the rotary assembly and between the rollers. Upon activating the motors, the tubing unwinds from the spool and exits in a continuous straightened condition from the drive and tension rollers. A rotary handle is employed for adjusting the tension in the tension roller. | 12-25-2014 |
