Abstract

The invention discloses an adjustable core mold for winding a transformer iron core. The adjustable core mold comprises a main plate and an ear plate which can conduct moving adjusting relative to the main plate, and the main plate and the ear plate are relatively fixed and are in detachable connection. When iron core single frames of different specifications are wound, the ear plate can be adjusted to enable the overall width and/or the overall length of the adjustable core mold for winding the transformer iron core to be larger or smaller, so that the universality of the core mold is greatly improved. The adjustable core mold for winding the transformer iron core is high in universality, suitable for winding iron core single frames of the different specifications, and capable of still being used for iron core winding after repeated heat treatment.

Description

technical field [0001] The invention relates to a wound core transformer core single-frame winding device, in particular to an adjustable mandrel for transformer core winding. Background technique [0002] Wound core transformer core single frame needs a mandrel of a certain size as support during winding. After the core is manufactured, the core and mandrel are annealed together. The mandrel after the annealing treatment will be deformed to a certain extent, and the mandrel after repeated annealing treatment will not be suitable for winding the single frame of the iron core when the mandrel has undergone repeated annealing treatment, and a new mandrel must be remade. [0003] In addition, in the prior art, a mandrel of one specification can only be applied to winding a single frame of wound core transformer core of one specification, that is, the length and width of the existing mandrel are fixed and can only be It is used to make a specific wound core transformer core sin...
