Wire foil winding mechanism method for three-dimensional iron core

Abstract

The invention provides a wire foil winding mechanism and method for a three-dimensional iron core, wherein the wire foil winding mechanism at least comprises an iron core clamping device which is used for adjusting the angle of a target three-dimensional iron core, a driven winding device which sleeves a target core column, and a driving gear device, wherein the driving gear device is meshed with and drives the driven winding device to rotate around the target core column, and the driven winding device drives a wire foil to be wound on the target core column in the rotating process. The wire foil winding mechanism can meet the requirement for large tension required by thick-specification foil strips or coils, the winding process is stable, and no damage is generated to an iron core column. Meanwhile, the wire foil winding mechanism is rapid and convenient to disassemble, the winding specification of the coil is enlarged, the requirement for large tension of coil winding is met, and the winding efficiency of winding is greatly improved while the winding quality of the coil is improved.

Description

technical field [0001] The invention belongs to the field of three-dimensional iron core winding, and in particular relates to a wire foil winding mechanism and method for three-dimensional iron cores. Background technique [0002] As the energy-saving efficiency of the three-dimensional iron core in the transformer becomes more and more prominent, the three-dimensional iron core transformer has been widely used in the industry. The stacked iron core is pulled out of the yoke, and then the high and low voltage coils are placed on the side and center columns of the iron core in turn, and then packaged with the pulled out yoke. [0003] However, due to the special structure of the three-dimensional iron core, the amorphous three-dimensional iron core is a triangular closed three-dimensional type, which requires that when the coil is wound, the three-dimensional iron core needs to be supported horizontally, and the high and low voltage coils are directly wound on the formed thr...

AI Technical Summary

Problems solved by technology

[0004] At present, there are a few high-voltage and low-voltage coil winding equipment for three-dimensional iron cores on the market. Three-point positioning is used for positioning of the winding mold, and the three-point positioning adopts the line contact in the high-pair contact. During the manufacturing process, the winding mold will touch or squeeze the iron core column, and when it comes to the high tension requirement of the coil, the winding mold will seriously damage the surface of the iron core column, which will cause potential risks or harm to the performance of the transformer formed later. , which greatly affects the quality and performance of the product
