An apparatus for winding up a metal strip into a coil. A frame in which a second counter-bending roller is mounted in a rotatable manner. The frame is movable with the aid of a second setting device between a coiler shaft position and a roller bed position. In the roller bed position, the second counter-bending roller alongside a first counter-bending roller acts as the roller bed roller of a roller bed which is arranged above the coiling device.

The invention relates to a device (11) and a method for producing transformer cores (12), the device comprising a retaining system (19) having a stacking table (18) for collecting sheets of metal (16) from which a transformer core (12) is constructed and having at least two positioning aids for the sheets, the stacking table forming a positioning surface (26) for the positioning aids and being equipped with the positioning aids, the stacking table and the positioning aids being realized such that a free positioning and a location-independent fastening of the positioning aids within the positioning surface is possible, the device having a positioning system (25) by means of which the positioning aids can be disposed on and/or be removed from the stacking table.

A compact heat treatment line can include a short heating zone capable of rapidly bringing a metal strip to a suitable solutionizing temperature through the use of magnetic rotors, such as permanent magnet magnetic rotors. A fast and efficient soaking zone can be achieved as well, such as through the use of magnetic rotors to levitate the metal strip within a gas-filled chamber. Magnetic rotors can further levitate the metal strip through a quenching zone, and can optionally reheat the metal strip prior to final coiling. Magnetic rotors used to heat and/or levitate the metal strip can also provide tension control, can facilitate initial threading of the metal strip, and can cure coatings and/or promote uniformity of coatings/lubricants applied to the metal strip without overheating. Such a heat treatment line can provide continuous annealing and solution heat treating in a much more compacted space than traditional processing lines.

A non-contact heating apparatus uses a series of rotating magnets to heat, levitate, and/or move metal articles therethrough. A first series of rotating magnets heats the metal article to a desired temperature. A second series of rotating magnets levitates the metal article within the heating apparatus and maintains desired tension in the metal article, including urging the metal article through the heating apparatus. The heating apparatus can extend sufficiently far to soak the metal article at the desired temperature for a desired duration. The rotating magnets can be positioned outside of an electrically non-conductive, heat resistant chamber filled with an inert or mildly reactive gas, through which the metal article passes in the heating apparatus.

For a rolled metal strip, in particular a steel strip; a drive roller unit deflects the metal strip from a first transportation direction to a second transportation direction, and the strip is then fed to a coiler. The metal strip is coiled in the coiler to form a coil having a coil diameter. Plastic deformation of an end portion of the metal strip is caused such that the end portion in its uninfluenced state is curved at a curvature radius. The plastic deformation of the end portion (8) is at least partially caused by an asymmetric impingement with a cooling medium (21) on the sides of the end portion (8). The impingement of the end portion (8) with the cooling medium (21) is performed across a length of the end portion (8) that is longer than half the outermost coiling of the coil (6) but smaller than the outermost coiling of the coil (6).

The invention relates to a method and a robot system (23) for producing transformer cores (12), sheets of metal (16) from which a transformer core is constructed being received on at least two stacking tables (18) by means of a multiaxial robot (22) of the robot system, the sheets of metal being supplied to the robot and stacked adjacent to the robot in at least two storage positions (31) for different sheets of metal by means of a conveyor device (29), the robot and the conveyor device being controlled by a control device (17), sheets of metal being collected from the storage positions and being stacked on the stacking tables by means of the robot disposed between and above the stacking tables.

A wire handling device for a manufacturing device includes an elongate first wire guiding device having a first guiding section for a wire to be guided along the first guide section, and an elongate second wire guiding device having a second guiding section for a wire to be guided along the second guide section. The wire handling device includes a support device, and the first wire guiding device and the second wire guiding device are placed on the support device. The support device is rotatably mounted about the rotational axis, and the first wire guiding device and the second wire guiding device are mounted so that they can be moved with respect to each other.

A coiling device that includes a coiler (1) having a coiling mandrel (3) for coiling a metal strip, and a coiling swing arm (4) having front and a rear pressure rollers (5, 6) and a deflection plate (7). A swing arm drive (8) lines up the coiling swing arm (4) with the coiling mandrel (3) and is driven away from the coiling mandrel (3). An upper duct flap (9) upstream of the coiler (1) in the feed direction (x) guides the metal strip (2). A flap drive (10) positions the upper duct flap (9) such that, when the coiling swing arm (4) is lined up with the coiling mandrel (3), the upper duct flap is arranged between the coiling mandrel (3) and the front pressure roller (5) of the coiling swing arm (4) or is arranged upstream of the front pressure roller (5) of the coiling swing arm (4).

Systems and methods of hot forming a metal blank include receiving the metal blank at a heater and positioning the blank adjacent a magnetic rotor of the heater. The systems and methods also include heating the metal blank through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal blank such that the metal blank is heated.

Systems and methods of threading a metal substrate on a rolling mill include receiving a coil of the metal substrate. The method also includes uncoiling the metal substrate from the coil while the coil and guiding the metal substrate to a work stand of the rolling mill with a threading system.
