Title:
WOUND IRON CORE, AND WINDING PROCESS AND WINDING DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/021570
Kind Code:
A1
Abstract:
The present application discloses a winding process for a wound iron core, comprising the following steps: feeding, placing a material strip on a feeding apparatus for feeding and conveying; heating, heating the material strip using a heating apparatus, so that the material strip reaches an annealing temperature; winding, winding the heated material strip on an iron core mold, to obtain an iron core frame. The present application also discloses a wound iron core manufactured by applying the winding process for a wound iron core, and a winding device for performing the winding process for a wound iron core. By applying the winding process for a wound iron core of the present application, the material strip is first heated and annealed, so that the iron core material reaches the annealing temperature, the wound iron core material does not generate stress, and the obtained iron core has stable performance. In addition, the wound iron core does not need to undergo a conventional annealing process, so that a large amount of production time is conserved, and energy consumption is reduced.
