AI Technical Summary
In existing power transformer component forming and processing equipment, the height of the limiting plate is relatively high, which requires operators to lift each silicon steel sheet sequentially and cross the height of the limiting plate, affecting installation efficiency. This is especially true when large-sized iron cores or stepped laminations are used, which can easily cause lamination misalignment or scratching of the insulation coating.
By employing a height limiting mechanism, a synchronous drive mechanism, and a synchronous lifting mechanism, and through the linkage of a motor and a gear rack, adaptive lifting of the limiting end is achieved, eliminating redundant actions of lifting across fixed limits, improving stacking efficiency, and avoiding edge deformation and coating damage of silicon steel sheets.
It achieves flush alignment between the limiting surface and the lamination layer during the iron core lamination process, improving lamination efficiency and avoiding edge deformation and coating damage to silicon steel sheets caused by excessively long lifting paths. It is particularly suitable for stacking large-size iron cores.

[0002] The power transformer is a kind of static electrical equipment based on electromagnetic induction principle, and the turns ratio of primary coil and secondary coil is used to realize voltage conversion and power transmission, and the core of the power transformer is formed by the high-permeability silicon steel sheet and the insulating winding, and the power transformer is widely used in power transmission and distribution system to improve voltage (reduce long-distance transmission loss) and reduce voltage (adapt to user demand), and the power transformer is a key device for efficient, safe and stable operation of power network.
