The utility model belongs to the field of transformer part production, and discloses a single-frame iron core storage device which comprises a tray and a supporting piece fixedly arranged on the tray, three supporting faces evenly distributed in the circumferential direction of the tray are arranged on the supporting piece, and the included angle between any two adjacent supporting faces on a horizontal projection plane is 60 degrees. A limiting check block is fixedly arranged at the position, corresponding to the radial outer side of each supporting face, of the surface of the tray, and a clamping space used for containing the single-frame iron core is formed between each limiting check block and the corresponding supporting face; on the horizontal projection plane, the top edge of the supporting face is arranged close to the center of the tray, and the bottom edge of the supporting face is arranged close to the edge of the tray. According to the utility model, three single-frame iron cores with the same energy efficiency grade can be stably stored at one place; the centralized storage device is suitable for the transformer part production industry and used for centralized storage of the three single-frame iron cores before splicing.

The application provides a braiding device and a braiding method for manufacturing a double-head closed-loop dense net support. The braiding device comprises a rotating disc, a spindle assembly with a plurality of spindles, the spindle assembly being mounted on the rotating disc, the plurality of spindles being arranged in sequence along the circumference of the rotating disc, every two spindles being symmetrical about the center of the rotating disc, and any two symmetrical spindles being used for sleeving a braiding ring so that the centers of all the braiding rings intersect at the center of the rotating disc; and a braiding core rod coaxially arranged with the rotating disc, the braiding core rod being movable in the axial direction of the rotating disc, the braiding core rod penetrating the center intersection area of the braiding ring and making the center intersection area located at a braiding starting point of the braiding core rod, and the braiding core rod tensioning all the braiding rings at the braiding starting point. The braiding device can braiding the double-head closed-loop dense net support on the braiding core rod at one time through the movement of all the spindles along the circumference of the rotating disc and the movement of the braiding core rod along the axial direction of the rotating disc, thereby effectively reducing the manufacturing difficulty of the double-head closed-loop dense net support and improving the manufacturing yield.
