The invention discloses an adjustable core mold of a wound core transformer. The adjustable core mold comprises a universal core mold body, a plurality of adjustable outer mold assemblies, tightening mechanisms and filling parts, wherein the adjustable outer mold assemblies are located on the periphery of the universal core mold, and at least one tightening mechanism corresponds to one adjustable outer mold assembly; each tightening mechanism comprises a tightening fixing part, a tightening part and a locking part, wherein the tightening fixing part is installed on the universal core mold, the tightening part is installed on the corresponding adjustable core mold assembly, one end of the locking part is fixedly connected with the tightening part, and the other end of the locking part is adjustably connected with the tightening fixing part; the portions between the universal core mold and the adjustable outer mold assemblies are filled with the filling parts. The adjustable core mold is applicable to manufacturing wound cores of various window heights and window widths, the universality and utilization rate are improved, and the manufacturing cost of the core mold is saved.
Description
technical field [0001] The invention relates to an adjustable mandrel for a wound core transformer. Background technique [0002] At present, conventional mandrels in the prior art are directly manufactured from a whole piece of steel plate according to the height and width of the iron core window. One mandrel can only be applied to one size of iron core, and iron cores of various sizes need to be prepared by oneself. A variety of suitable mandrels are not universal, and the manufacturing cost is relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide an adjustable mandrel for wound core transformers, which can be applied to the manufacture of wound cores with various window heights and window widths, and improve its versatility and utilization rate , save the manufacturing cost of the heart mold. [0004] In order to solve the above-mentioned technical proble...
