Embodiment Construction

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0027] like figure 1 As shown, the electromagnetic stirrer coil winding device includes an iron core mold 1, a flat copper wire coil support frame, an iron core mold driving mechanism and two sets of compression molding mechanisms. The two sides of the iron core mold 1 are parallel, and the two ends of the iron core mold 1 are in a convex circular arc structure.

[0028] The iron core mold driving mechanism includes a worktable 2, a motor 3, a base I22 and a support rod 23, such as figure 2 shown. The base I22 is arranged below the worktable 2, the worktable 2 is fixedly arranged above the base I22 through the four support rods 23 evenly distributed at the bottom, the motor 3 is fixedly arranged in the upper middle of the base I22, and the power output shaft of the motor 3 is vertical It goes up through the workbench 2 and rotates w...

Abstract

The invention discloses a coil winding device for an electromagnetic stirrer, comprising an iron core mold, an iron core mold driving mechanism and two sets of compression mold mechanisms. The pressure film block, the sliding pressure film block, the pressure spring and the guide rod, the sliding pressure film block is arranged between the fixed pressure film block and the iron core mold, and the guide rod passes through the middle of the fixed pressure film block. Guide through hole, the spherical end of the guide rod extends into the spherical concave hole of the sliding pressure dynamic film block and rotates with it; between the sliding pressure dynamic film block and the fixed pressure film block and close to the sliding pressure dynamic film block Pressure springs are respectively arranged on both sides, a magnet is fixed on the sliding pressure film block, and an electromagnetic coil is fixed on the fixed pressure film block. The invention adjusts the current of the electromagnetic coil by controlling the switch, so that the sliding pressure film block is pressed against the flat copper wire with an appropriate force, so that the flat copper wire wound on the iron core mold is close to one layer from the inside to the outside.

Description

technical field [0001] The invention relates to a crystallizer electromagnetic stirrer, in particular to a coil winding device of the electromagnetic stirrer. Background technique [0002] The essence of the electromagnetic stirrer is to strengthen the movement of molten steel by means of the electromagnetic force induced in the liquid phase cavity of the casting billet. Specifically, the alternating magnetic field excited by the stirrer penetrates into the molten steel of the casting billet, and a current is induced in it. The induced current interacts with the local magnetic field to generate an electromagnetic force. The electromagnetic force is a volume force and acts on the volume element of the molten steel. , so as to promote the movement of molten steel. [0003] The coil in the electromagnetic stirrer is an important part of the crystallizer electromagnetic stirrer. After the coil is made, it has an arc-shaped structure with convex ends. At present, the production...
